Title: How to find a replacement ribbon cable
Post by: Yamin on July 22, 2019, 10:32:30 am
Hi, I have a busted ribbon cable. I have been searching online with numbers and letters written on the cable with no luck. I have attached a picture of the cable. Thanks in advance for the help.

P.s - It would be great if you could explain to me all the writing on the cable.

They're very common. Length, pitch and number of contacts matter of course, they're available from China in many variations.
It's also possible with some precision to use one with too many contacts, if no perfect match can be found.. just cut away the outer contacts.

This is the company that made that one: http://www.bew.co.jp/products/03.html (http://www.bew.co.jp/products/03.html)
But as the poster above says, it's just a ribbon cable. Any of the huge number of manufacturers out there will be able to make an equivalent, given the specifications.

Seems to me that searching on AWM 20624 should get you results.  AWM is a standardized means for marking component/appliance wires.    I don't know whether type 20624 already specifies the pitch.  If it does, you'd still have to find a source with the right length and number of contacts/wires.

80C is the temperature rating of the cable material, or 80 degrees C.  60V is the voltage rating of the cable material, or 60 volts. VW-1 is the flammability rating of the jacket material.   The reversed RU is a variation of an Underwriters Laboratory marking.  Bando - SH is likely some form of brand marking, but that doesn't mean you can always find them or buy from them as an end customer.

This type of cable is called FFC cable and large variety of length & pin count are available from Aliexpress.

you need to know the ffc / fpc  pitch   take a caliper    ex:  0.5 or 1 and the numbers of pins,  they are usually not expensive,  and to know  if you have a straight cable on a reversed ending 

Check if the pins are on the same side, or one is under and the other on top ...

The pitch of the contacts/pins. The distance from the center of one pin to the center of the pins on either side.

If measuring by ruler and eye, it's usually best to measure from first to last pin and divide by the number of pins-1.
