PIDG Terminal Part Numbers

I am likely overthinking this, but i am trying to put together a ready reference of part numbers from Digikey to aid in ordering electrical components - but it is HARDER THAN I REALIZED!

Take a standard #10 Stud, red, 16-22 AWG terminal.
Here it is from Spruce - PN 36154
https://www.aircraftspruce.com/catalog/elpages/insulterms.php

and the same thing at Digikey https://www.digikey.com.au/product-detail/en/te-connectivity-amp-connectors/36154/A1062-ND/20551

However, looking at the datasheet for this connector it shows the diameter of the insulation as being 0.105-0.140, and they are $0.44, BUT -> Googling around, i find that 22 gauge tefzel has a diameter of 0.052".


Doesn't this mean that for 22 AWG there would be no strain relief on this connector? Why not just use automotive connectors instead? Should i use the PIDG ones and use some heatshrink?

Just wondering what everyone uses and if anyone had a ready reference of part numbers for PIDG terminals that they use.

As an aside, searching around a bit more, you can but PIDG terminals that match the insulation diameter - for example, instead of 36154, there is 2-36153-3 (red with green stripe) - they run at $0.99 (double the price) - the datasheet for these lists the insulation diameter for 22AWG as 0.038" - 0.110" - within the range for a 0.052" tefzel insualtion.
Here is the digikey link https://www.digikey.com.au/product-...ity-amp-connectors/2-36153-3/A27337-ND/298779

Here is a digikey link for all connectors what have a 0.038-0.110" insulation diameter - https://www.digikey.com.au/products...ColumnSort=1000011&page=1&stock=1&pageSize=25

Should i be paying twice as much and buying connectors for each specific wire diameter?? :confused::confused::confused:

Stein and B&C have connector kits but they don't list the specific part numbers for the connectors in their kit.

Thanks - likely overthinking this but want to make sure i do the right thing.

I found these from Zoro, they are very high quality nylon double crimp terminals and the low price is great.

Don't use automotive connectors. The problem with TE Connectivity is they have TOO MANY CHOICES! I printed out their catalog pages from their website
https://www.te.com/usa-en/home.html
Then I went through it and highlighted the wire sizes I was going to use, the stud size I was going to use, the part numbers that were available as loose pieces (as opposed to tape mounted) and finally if they were qualified to MS25036. The latter mainly as a filter, but I think another level of traceability if not quality. Finally whether they were available from DigiKey

Here's my list:
Ring Tongue Terminals
Wire size Stud Size P/N
22-16 #6 36149
22-16 #8 320551
22-16 #10 36153
22-16 1/4 320571
22-16 5/16 320572
16-14 #6 51864
16-14 #8 51864-1
16-14 #10 51864-2
16-14 1/4 320563
16-14 5/16 320575
12-10 #6 320567
12-10 #8 320568
12-10 #10 36161
12-10 1/4 320569
12-10 5/16 320576
12-10 3/8 35112

Also needed are the 0.250 series FASTON terminals for 1/4" male tabs
Wire size P/N
22-18 640903-1
16-14 640905-1
14-12 42844-1
12-10 640907-1

Hope this helps.
 
Hi Terry,

You are not wrong about the number of choices! Thanks for sharing your info.

For example
Here's my list:
Ring Tongue Terminals
Wire size Stud Size P/N
22-16 #6 36149
22-16 #8 320551

Just picking the top two I your list:
36149 & 320551 - according to the data sheets these are both for 0.080" ~ 0.125“ insulation diameter - or in tefzel that’s 16-12AWG. Would we ever have a 16AWG into a #6 stud? (Like on a switch?)

Then in place of 320551 there is 31890 - seemingly the same product until you go to the data sheet, and 31890 insulation diameter is 0.105" ~ 0.140" (even bigger - 12-10 AWG. This is the part number listed on spruce.

I am thinking I should just buy the red with a green stripe terminals as they allow a diameter of 0.038-0.110” which allows for 22-14 tefzel insulation diameters. Or am I wasting my money?

Having used the terminals you have listed, did you feel they crimped onto the insulation ok?

ARGH!

This appears to be the manufacturer's website:
http://www.quickcable.com/products.php?pageId=85

The connectors appear to be comparable to PIDG connectors but a lot less expensive. Some of the fully insulated connectors on digikey are going for over a buck a piece and that's just getting out of hand. I use this type of crimp terminal only, even if its going on something like a lawn mower.
 
I ordered a package of these from zero after finding them and also looked up the manufacturers website, I figured they were cheap enough to buy some just to get my hands on them and see if they were any good, I was very happy to see how high quality they were when the test package showed up. I ordered more afterwards and have used them exclusively since. Very good connectors. Like you Bob, I wouldn’t use the cheap vinyl automotive type connectors on anything, I throw them away.

Quickcable is the US seller/distributor, they are manufactured by KS Taiwan, If you look closely at the photo I posted earlier you can see the KS/part number/wire size stamped on each connector.

I've used some but not all of the terminals, still have a lot of wiring left to do. I was lucky enough to have retained a genuine AMP terminal tool from a previous project/employer, so I only had to buy new genuine dies for the above terminals. I think this is the key to good wire terminations: quality terminals applied with the manufacturer's recommended tool. The cost of terminal tools or dies has given me pause when ordering them, but I've never regretted buying quality tools (tools that will last for the rest of my life :D). The manufacturer's recommended tools/dies do a good job of crimping onto the wire as well as the insulation.
 
Stein has a good selection of terminals in his terminal kit - I think I would spend more than $85 in time thinking about it and manually ordering! - this worked out well for my -10 - ended up using 2 of them, with not many left over.

Thanks - Stein is great but the shipping is prohibitive to Australia - $55 USD minimum. I can get everything from Digikey and the shipping is free - just have to have the manufacturers part numbers. Unfortunately stein doesn?t list part numbers, nor any data sheets on what terminals they sell.

Thanks for all the replies, and links to alternate products, but I?m not seeing any concerns around the recommended insulator diameters, which is the real issue here for me. I know there are thousands of stein panels in service - but maybe they all won?t make 1000 hours before terminals start falling off because the terminals were not crimped onto the insulation properly?

Maybe I?ll email stein or b&c and ask about what insulation diameters their terminals are designed for? Hoping someone before me may have already come across this and have an answer tho! :cool:
 
Aussie suppliers

Trent, I sent you a PM with info on a local supplier that I've used for electrical (and other) parts for my -9 build. It might help, it might not.
 
Hi Geoff,
Can you please send me a PM with the details also. I am wiring and have to buy more terminals.
Thanks,
Joe
 
Hi Trent,

RE: your original post; I suspect that you are overthinking it a bit. Note that, for instance, the TE-AMP 36154 you linked is spec'd as having a wire gauge of 22-18 in milspec, and 22-16 in commercial use. Consider that even with the milpsec size range, there is a *huge* variation in insulation diameter across those three sizes, even if you restrict your wire selection to one insulation type (there are numerous milspec insulations; you can likely still find a milspec for PVC). The military seems ok with a 3-gauge-range, both in wire gauge and insulation diameter. All you really need from the insulation 'grabber' in the connector is that it stabilize the wire outside the electrical crimp area, without cutting completely through the insulation. The insulation crimp exists to prevent the wire from flexing at the electrical crimp point, which is a stress riser, just like a solder joint.

It pays to remember that what we're doing isn't rocket surgery. :) If that wide range of sizes in on connector is good enough for milspec, it's plenty good enough for me.

I am sure you are right.

Thanks Geoff. You are right - i am better to buy local than overseas, much quicker i think (even though digikey is pretty quick). I think i will just go for the listed part numbers in the AAE catalogue.

Wayne Wire

Trent, I get all my PIDG terminals from Waytek Wire here in the USA. I generally buy the terminals in packs of 100. Generally pay $0.20 a piece or less for them. Not sure what their shipping policy to Australia is? Their shipping to points in the USA is very reasonable.
