What does the dot behind a part number mean?

Perhaps if we knew what catalog those clips were from... Never mind, google finds those are Farnell stock numbers.

Since this occurs in part numbers from two different sources of two different series, my initial reaction would be that it represents some distinction in the catalog house's system. Such things as whether they are lead free or not often get noted in part numbers.

SInce the alternative parts seem to link to the same data sheets from the manufacturers, I am led to guess the dot has to do with alternative sources for the same part.


A quick query to Farnell ought to answer this.

he, if you read it all, its obvious they have problemes with typing

looks funny, eh

even if same type and code number, still different parts number.....maybe thats what dot indicates

I suspect error comes from software error due to communication error
like if two identical parts are stored with different explanations a software "think" they are different
just two different people typing different about the same part
dot is manually placed at the important number, by which they are sorted by software, and alike
 
In case of the 2604 one is a tube of 50 pieces, the other is a single chip.
edit: and with the 4562 the one is US stocked and the other is local stock.


I can see why they would need two exactly the same parts but with different order codes due to these differences. They probalby have some technical reason why the mfg. part number cannot be exactly the same so they add the dot to differentiate.

I can see that this is obviously a critical issue so I contacted Technical support at Farnell and requested an answer.
After all they only have nearly half a million product lines.
This is Farnell's reply.....

I'm sorry but the truth is a little less interesting than the theories.
When we've got the same manufacturer's part number but changed something (eg it's now a RoHS compliant number) they stick the extra "." on the end so that the new stock number comes up first on any search.
You'll find the older stock has the full stop (or two) on the end of the part number.

Maybe we can draw a full stop to this conversation now:D
 
In addition to MACE1337’s answer there are also other reasons why you could possibly see this. In any industry that utilizes electric power with the exception of third world countries, the design plans for electrical components generally are inspected and a certain number are stress tested and the approved for distribution.

Here in the US we deal with UL (Underwriters Laboratories) and other countries generally have their own regulatory group or groups. In 19 years of doing IBM Mid-Range (AIX/UNIX) administration and hardware support (first micro-channel and then P-series), I have seen cases where the same exact part has been released under 5-10 different part numbers. One number for the first release, then second number for a release with a different micro-code (binary card instructions) or a card that is only authorized (designed and tested) for releaswe in a specific country, in one case that was Brazil.

I agree the syntax is begging for misunderstandings on the part of the customer and overworked warehouse staff while pulling pick tickets.
