Is there a pin-compatible replacement for 640456-6?

While several parts share the same 6-pin, 2.54mm pitch layout, a pin-to-pin replacement has not been verified. Critical dimensions and contact plating must be checked against the datasheet before substitution.

What risks should I check before replacing 640456-6?

First, ensure the replacement is an unshrouded header, not a shrouded type (like XH series). Second, verify all mechanical dimensions from the datasheet. Third, consider the impact of different contact platings (e.g., gold vs. tin) on your mating connector.

640456-6 Alternatives, Datasheet & Cross Reference | TE Connectivity

TE Connectivity's 640456-6 is a common 6-pin, 2.54mm pitch unshrouded header. Alternatives exist but require careful review of contact plating and mechanical dimensions to ensure compatibility.

AI replacement insight

Package riskmedium

Critical to verify header is unshrouded and all dimensions match datasheet.

Electrical risklow

Most alternatives offer equivalent or better electrical ratings.

Application riskmedium

Plating differences (Gold vs. Tin) require checking mating connector to avoid corrosion.

Can it be replaced directly?

No verified direct drop-in replacement has been identified. Several functional alternatives exist but require engineering review of mechanical drawings and contact plating.

Best replacement path

Consider generic 2.54mm headers like HCTL PZ254-1-06-Z-8.5, but verify mechanical drawings and the impact of gold plating.

Main risk

The primary risk is mechanical incompatibility. Many similar-looking parts are from specific, non-interchangeable connector families (e.g., JST XH).

Recommended alternatives

A 6-pin, 2.54mm pitch straight header with upgraded gold plating and high-temperature housing.
