BXCONN
A strong alternative with matching orientation and electrical ratings; verify footprint.
HCZZ0039-2 is a 2-pin, 1.0mm pitch vertical SMT header. Several alternative connectors are available with matching electrical ratings, but require careful verification of mechanical drawings to ensure PCB footprint compatibility.
Several candidates match the 50V/1A rating.
Requires verification of the mechanical drawing and PCB footprint before substitution.
No drop-in replacement is confirmed. WF-1E100A2P is a strong candidate that requires a mechanical drawing review to ensure it fits your PCB layout.
Use a vertical 1.0mm 2-pin header like WF-1E100A2P after verifying its PCB footprint against your design.
The primary risk is a mismatch in the PCB solder pad layout (footprint), which is common even among dimensionally similar connectors.
