A potential alternative with matching pitch, position count, and current rating, but requires mechanical verification.
PHOENIX CONTACT 1803277 is a widely used 2-position, 3.81mm pitch vertical PCB header for board-to-wire connections. This page explores functional alternatives and provides guidance for selecting a suitable replacement.
PCB footprint, height, and mating interface are not verified and may differ.
Most candidates meet or exceed voltage/current ratings, but one has a lower IEC current rating.
Direct replacement for 1803277 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
XY2500V-E-3.81-2P and MX15EDGVC-3.81-02P-GN01-Cu-A are the most promising alternatives as they match key electrical ratings and orientation. However, you must verify their mechanical drawings.
The primary risk is mechanical incompatibility. This includes the PCB footprint, connector height, and the dimensions of the shroud, which could prevent mating with existing plugs.
