I am looking for a 1.27mm shorting jumper and when I look at the datasheet the drawing shows what I assume is a range of dimensions for different size pitches for the two pin package, like for example 1.0 over 2.54. Am I correct in assuming that this is a generic drawing for components ranging from pitch 0.1mm to 2.54mm. Sorry for the basic question but I have to start somewhere Thanks

 

No I'm afraid you're not correct. I think you are referring to the pitch of 0.1/2.54, that's 0.1 inch/2.54 mm. Only one pitch size on this drawing.

 

Thanks pwdixon. What I find confusing is that the first link in my question is for a part of 1.27mm pitch and the datasheet for that product, of that pitch leads to my second link with this ambiguous information. I see what you are saying and it makes sense, but did you look at the first link and see what I am saying please.

 

hi,
There is some ambiguity between the Data sheet, which shows a 2.54mm pin pitch with a 0.100mm tolerance and the suppliers data clip which shows a 1.27mm pin pitch.

Is this what you are asking.?
E

 

Yes ericgibbs sort of thanks So you are saying that the 0.1/2.54 is a 0.1mm tolerance whereas pwdixon is saying that the 0.1 in 0.1/2.54 is the imperial equivalent of 2.54mm. Unfortunately now I am even more confused with two completely different explanations or am I misunderstanding one or both of you

 

Those two numbers are definitely the imperial and metric values.

The two datasheets (one via Mouser and one given directly by you) are the same, probably the Mouser summary of 1.27mm is wrong.

 

hi pedro,
As you know 2.54 mm equals 0.1 inch and 1.27 mm equals 0.05 inch
Some drawings do use a similar method of showing the tolerances of the main dimension.

What is the point which is causing you concern.?

E

BTW: I am not disputing what 'pwd' is posting, my concern was the difference between the suppliers 1.27mm and the datasheet showing 2.54mm

 

It doesn't help that molex have changed the part number for that particular connector series.

 

Thanks to both of you. I just wanted to try and confirm that the part in the first link of my initial question had a pitch of 1.27mm. I thought that the best means of confirming this was to look at the datasheet but this is when I became confused. You electronics guys are certainly up against it with ambiguous information like this being provided I will assume that the initial product description is correct

 

This is not a 1.27mm part.

 

I am more confused than I was two hours ago Why does this link say pitch 1.27mm please See here

Because Mouser made a mistake.

 

Look at Digikey
http://www.digikey.co.uk/product-search/en?FV=ffec2ba4

and
http://www.molex.com/pdm_docs/sd/015291024_sd.pdf

 

So the Digikey link goes to a 2.54m pitch component that I do not want - Thanks dxdixon

surely you know what the mating part is, so you should easily be able to identify the matching connector

 

It connects to a 2 pin header strip to bridge it hence the name "shorting jumper" Look this is just going around in circles so thanks for your help and have a nice day

 

hi pedro,
Is it possible to measure the actual distance between the two pins that the jumper is going to link.?
Most jumpers I have used are 2.54mm [ 0.1inch]
Many scrap PC, PCB's have loads of such jumpers you could recycle

Thanks Eric. Yes it is definitely 1.27mm. It is on a very small radio controlled flight control circuit and that stuff is tiny I managed to find what I need at Digikey. Thanks for your suggestion you are a true gent
