HCTL
A 4-pin, 1.25mm pitch straight through-hole header with matching electrical ratings. A strong candidate pending drawing verification.
Finding a substitute for the Yuandi WAFER-MX1.25-4PZZ, a 4-pin 1.25mm straight through-hole header, requires matching the mechanical footprint and electrical ratings. Several alternatives exist with similar specifications.
Requires user to verify PCB footprint and connector height from datasheet drawings.
Multiple candidates match the 1A, 125V rating.
This is a common connector style with alternatives from multiple manufacturers.
Direct replacement for WAFER-MX1.25-4PZZ should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Prioritize straight through-hole headers with 1.25mm pitch and 4 pins, such as HCTL HC-1.25-4AW or Megastar ZX-MX1.25-4PZZ.
Mechanical footprint mismatch is the primary risk when substituting this type of connector.
