Is there a pin-compatible replacement for XDZ254-1-04-Z-2.5-G1?

No candidate has been confirmed as a direct pin-compatible replacement. MTP125-1104S1 and 640456-4 share the same 1x4 pinout and 2.54mm pitch, but full mechanical dimensions and plating must be verified from their datasheets to ensure true pin-to-pin compatibility.

What risks should I check before replacing XDZ254-1-04-Z-2.5-G1?

Before replacing, you must verify: 1) Mechanical Dimensions: Ensure pin length, post height, and insulator dimensions fit your PCB and mating connector. 2) Contact Plating: The target uses Gold; a Tin-plated substitute may have different performance. 3) Current Rating: Ensure the substitute meets or exceeds the 3.0A rating of the original part.

XDZ254-1-04-Z-2.5-G1 Alternatives, Datasheet & Cross Reference | XUNDA

XDZ254-1-04-Z-2.5-G1 is a standard 4-pin, single-row, 2.54mm pitch straight male header. While several alternatives with the same basic configuration exist, they require careful review of mechanical dimensions and contact materials to ensure suitability.

AI replacement insight

Package riskhigh

While pitch and pin count match, other mechanical dimensions are unverified and can prevent proper assembly or mating.

Electrical riskmedium

Contact plating differences (Tin vs. Gold) and unconfirmed current ratings require careful evaluation for application suitability.

Can it be replaced directly?

No direct drop-in replacement has been verified. MTP125-1104S1 and 640456-4 are potential functional alternatives that require engineering review before use.

Best replacement path

Verify MINTRON MTP125-1104S1 for mechanical dimensions and plating. If tin plating is acceptable, TE Connectivity 640456-4 is a strong candidate once its current rating is confirmed.

Main risk

The primary risks are mechanical incompatibility due to different pin lengths or insulator heights, and performance degradation from different contact plating (e.g., Tin vs. Gold).

Recommended alternatives

A potential functional alternative with matching pitch, pin count, and current rating, but requires mechanical and material verification.
