Is there a pin-compatible replacement for PZ254-1-04-Z-2.5-G1?

No pin-compatible replacement has been verified. While several candidates like ZX-XH2.54-4PZZ-R share the same physical footprint (4-pin, 2.54mm pitch, straight), they differ in critical electrical properties like contact plating or current rating. Engineering validation is required.

What risks should I check before replacing PZ254-1-04-Z-2.5-G1?

The main risks are electrical and reliability-related. Check if a lower current rating (e.g., 2A vs 3A) is acceptable. Also, verify if substituting gold plating with tin plating meets your product's requirements for contact resistance, corrosion, and mating cycles.

AI replacement insight

Electrical riskmedium

Some candidates have lower current ratings. Plating change affects contact resistance.

Package risklow

Several candidates match the 4-pin, 2.54mm straight header footprint.

Sourcing risklow

Alternatives are available from multiple manufacturers.

Can it be replaced directly?

No direct drop-in replacement was found. All candidates have different contact plating or lower electrical ratings, requiring careful engineering review before substitution.

Best replacement path

ZX-XH2.54-4PZZ-R offers the same current rating and footprint but uses tin plating instead of gold, which requires application review.

Main risk

The primary risk is the contact plating downgrade from gold to tin, which can affect long-term reliability, corrosion resistance, and mating cycles.

Recommended alternatives

Matches form factor and current rating, but has tin plating instead of gold, requiring review.
