Likely pin-compatible 4-pin header with matching pitch and explicit single-row configuration.
HCZZ0126-4 is a standard 4-pin, 2.5mm pitch straight male header. Numerous cross-vendor alternatives are available, making it easy to source replacements, provided mechanical dimensions are carefully checked.
Must verify datasheet for pin length, shroud dimensions, and single-row configuration.
Most XH series parts share the same 3A/250V rating, but this should be confirmed.
This is a very common connector type with many manufacturers and high availability.
Direct replacement for HCZZ0126-4 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Use a cross-vendor XH-series equivalent like DEALON XHB-D-4A, after verifying the mechanical drawing.
The primary risk is mechanical mismatch in pin length, shroud size, or mounting orientation (straight vs. right-angle).

Verified drop-in options for HCZZ0126-4 are limited in the current batch. Review candidates marked Strong match or Datasheet verified, and validate package, pinout, and electrical limits before committing a BOM change.
