Is there a pin-compatible replacement for WJ103-5.0-03P-14-00A?

There are no automatically verified pin-compatible replacements. However, parts like XY2500V-B-5.00-3P share the same pitch and position count, making them strong candidates for a pin-compatible match after you verify the mechanical drawing in the datasheet.

What risks should I check before replacing WJ103-5.0-03P-14-00A?

Before replacing, you must verify the mechanical dimensions and pinout from the candidate's datasheet to ensure it fits your PCB layout. Also, check for any differences in wire gauge range or material specifications that could affect your application.
