Is there a pin-compatible replacement for WAFER-GH1.25-5PLB?

A direct pin-compatible replacement has not been verified. Candidates like HC-1.25-5PLT match key specs but require a datasheet comparison to confirm the SMT footprint and housing dimensions are identical.

What risks should I check before replacing WAFER-GH1.25-5PLB?

The main risk is mechanical incompatibility. Ensure the substitute's PCB footprint, height, and mating interface match the original. Also, verify the contact material is acceptable for your application's lifecycle requirements.

WAFER-GH1.25-5PLB Alternatives, Datasheet & Cross Reference | XUNPU

Finding a replacement for the XUNPU WAFER-GH1.25-5PLB 1.25mm pitch header involves matching the 5-pin SMT footprint and GH-series mating interface. Alternatives exist with similar or better electrical ratings.

AI replacement insight

Package riskhigh

Footprint and mating interface are not guaranteed to be compatible across different '1.25mm header' families.

Electrical risklow

The primary candidate offers superior voltage and current ratings.

Sourcing risklow

1.25mm pitch headers are a common component type with multiple manufacturers.

Can it be replaced directly?

No verified direct drop-in replacement is available. HC-1.25-5PLT is a strong candidate that requires mechanical verification.

Best replacement path

Search for JST GH series or Molex PicoBlade compatible 1.25mm pitch, 5-pin vertical SMT headers. Prioritize candidates with mechanical drawings.

Main risk

Mechanical mismatch. The PCB footprint or mating connector may not fit, potentially requiring a board redesign.

Recommended alternatives

A 5-pin, 1.25mm pitch SMT header with higher voltage/current ratings. Mechanical fit requires verification.
