Strong match with identical key electrical and mechanical specs; appears to be a pin-compatible XH-style header.
Find substitutes for the HANBO WAFER-HA254Z-4A, a 4-pin 2.54mm pitch straight header. This guide reviews pin-compatible and alternative options, highlighting key differences in electrical ratings and mechanical fit.
Several candidates have a lower current rating (2A vs 3A).
For straight-mount candidates, form factor is consistent. Right-angle parts were rejected.
This is a common connector type with multiple vendors available.
Yes, ZX-XH2.54-4PZZ-R from Megastar is a likely pin-to-pin replacement for WAFER-HA254Z-4A, matching pin count, pitch, orientation, and electrical ratings. Verification of the connector series compatibility is recommended.
The strongest candidate is ZX-XH2.54-4PZZ-R, which matches all key parameters. Other alternatives exist but have lower current ratings, posing a downgrade risk.
The main risk is using a substitute with a lower current rating, which could lead to overheating or failure if the application draws close to the original's 3A limit.
