Is there a pin-compatible replacement for WAFER-XH2.54-3PJK?

Several parts like HANBO's WAFER-XH254Z-3AM and Megastar's ZX-XH2.54-3PZZ-R are likely pin-compatible as they share the same pin count, pitch, and mounting style. However, a datasheet review of mechanical dimensions is required to confirm a true drop-in fit.

What risks should I check before replacing WAFER-XH2.54-3PJK?

The main risks are mechanical incompatibility and electrical downgrades. Ensure the substitute's shroud design and pin dimensions match your layout. Also, verify the current rating is at least 3A, as some alternatives offer lower ratings.
