Strongest candidate with matching electricals and through-hole mounting, but requires footprint verification.
HC-1.25-6A is a 6-pin, 1.25mm pitch through-hole header. Finding a direct pin-compatible replacement requires careful verification of mechanical drawings, as several functional alternatives exist with different mounting types.
PCB footprint for through-hole headers is not standardized and requires datasheet verification.
Key electrical ratings (1A, 125V) are common and easily matched by alternatives.
Direct replacement for HC-1.25-6A should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Verify the footprint of ZX-MX1.25-6PZZ for a potential drop-in, or redesign the PCB for a more available SMT alternative like HC-1.25-6PWT.
Mechanical footprint mismatch is the primary risk. Even with the same pitch and pin count, body dimensions and pin locations can vary.

| Feature / factor | HC-1.25-6A | ZX-MX1.25-6PZZ | HC-1.25-6PWT | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | Through Hole Header | Through Hole | - | Surface Mount (SMT) — Candidate is SMT right-angle, target is through-hole straight. Requires PCB redesign. | |
| Current | 1 A | 1.0 A | - | 2 A — Higher current rating is an upgrade. | |
| Voltage | 125 V AC/DC | 125 V AC/DC | - | 250 V — Higher voltage rating is an upgrade. | |
| Temperature | Not specified | -25°C to +85°C | - | -25°C to +85°C — Operating temperature range is standard. |
Verified drop-in options for HC-1.25-6A 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.
