A 4-pin, 1.25mm pitch header with superior voltage (250V) and current (3A) ratings.
ZX-MX1.25-4PJK is a 4-pin, 1.25mm pitch straight through-hole header. Several cross-vendor alternatives with matching form, fit, and electrical ratings are available.
Candidates have equal or better ratings.
Pin-to-pin compatibility requires user to verify datasheet drawings.
Direct replacement for ZX-MX1.25-4PJK should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Start with Datasheet verified or Strong match candidates for ZX-MX1.25-4PJK, then review parametric alternatives for package and electrical fit.
Mechanical fit. While datasheets suggest compatibility, physical verification of the footprint is crucial.
