FYI, neither one is correct for DuPont pins: SN-28B is for 2.8mm spade (Faston) connectors, SN-48B is for 4.8mm spade connectors. All but two cheap “DuPont” crimpers I have ever seen on eBay/Ali do DuPont wrong: these pins are designed for a round, non-piercing insulation crimp, which is why on a tool like these which makes the m-shape insulation crimp, it spreads wrong and won’t go in the housing. I’ve just ordered one, we shall see if it actually gets DuPont crimps right!!!
That sounds reasonable. To be honest, when i was doing this i had difficulties to even determine how exactly "DuPont" was specified. But they get the job done, at least well enough for my amateur level of precision. People really hate this video =D Anyway, thx for the feedback. Have a good one.
@@comalab2387 Oh man, no kidding about it being tough to figure out what "Dupont" pins actually are!!!! I spent many, many hours researching it until I found tech.mattmillman.com/info/crimpconnectors/ It is an invaluable resource, and even it isn't 100% complete. Up to now, I've been muddling along with an SN-28B. Like you said, it does the job. But it really makes the job harder than needed, and it isn't compatible with all the "dupont" contacts I ordered. (In particular the female ones, as some types are shorter than others, and the short ones are nearly impossible to do reliably in the SN-28B since you're working totally blind. The longer ones work OK.) And of course it also depends on whether the contacts are made for thinner or thicker wire, which the eBay/Ali vendors never specify, or even seem to care about. The ones for thicker wire tend to work far more predictably in an SN-28B. FYI, the new crimper I ordered on Ali is called an SN-4228B. I'm anxious to see how it fares. The listing is, at least, quite specific about which jaw opening is for which connector type, and it covers all the small connectors I want to do. P.S. FWIW, I did not downvote your video!
@@tookitogo That's good to hear! Maybe it evens out to 50:50 some day, i'd take that as a win. Anyway, I checked the link you kindly provided and it does seem to offer valuable additional info. I pinned your comment, perhaps it will help another poor soul to explore the world of crimping. Cheers!
@@blogJM FYI, 5557 appears to be Molex Mini-Fit Jr. I don’t have any experience with those myself, but the SN-4228B’s compatibility specs (which have proven to be actually accurate) claim 5557 compatibility. A quick look at the 5557 contact drawings makes me think it should work. It’s got symmetrical insulation wings (already making it much less fickle than DuPont), and eyeballing the drawing, the total crimp area seems to be around 4mm wide, matching the 4mm jaw thickness of the SN-4228B. As far as cheap crimpers go, I’ve found it to be a very versatile tool, so I’d give that a shot.
It's just the die that's different, they support separate diameter size/gauge ranges, they are interchangeable and there's many more available for different connectors also.
@@lkutomochi Well, generally speaking, the e.g. SN-28B model number refers to the whole tool (dies and handle), whereas the dies will be just "28B". Some tool manufacturers have various versions of the handles, so you might have SN-28B for one handle, DN-28B for another handle, etc, but all using the same 28B dies. (For the larger type of handles, you'll often see the dies sold under "Axxx", with standard handles as "HS-xxx" or "LY-xxx", e.g. A03B and HS-03B for uninsulated spade terminals.)

Are there specific model would you recommend for 5557 pins that are typically used in power supply connectors?

The ending was extra helpful. 🤣

yup, explains the screw i guess.
loved the ending, the do look like dinosaurs...
Ya I'd have more subscribers if i made the channel about tools getting intimate. ;)
the music also helps ;)
It would be good if you could mention the names of the crimpers instead of saying "this one".
SN-28B good. SN-48B not so good. For that specific task that is.
Do you know you could put other crimping pliers into the SN-48B?
Can't say I do.
As I understand the crimpers itself are the same, but jaws are different. SN28B and SN48B are the jaws, not crimpers' model.

title "SN-28B vs. SN-48B Crimp-Off" conclusion "this one".
Which one? You never said.
"get this one, not this one", LOL, which?
the big one. giggitty.
They are the exact same but with a different head?
It got a little weird at the end. 😂
Sad
