PZ254-1-05-Z-8.5
HCTL
Needs validationlow risk
A 5-pin, 2.54mm pitch straight header from HCTL. Appears to be a strong form-fit-function match.
Best Alternatives to 640456-5
TE Connectivity's 640456-5 is a standard 5-position, 2.54mm pitch straight male header. While many manufacturers produce similar connectors, finding a suitable replacement requires careful verification of mechanical dimensions like pin length to ensure a proper fit.
AI replacement insight
Package riskhigh
Pin lengths and housing dimensions are not standardized and must be verified from datasheets to ensure fit.
Electrical risklow
Most similar headers have comparable voltage and current ratings, but should be confirmed for the specific application.
Can it be replaced directly?
No drop-in replacement has been verified. However, several parts like HCTL's PZ254-1-05-Z-8.5 are strong candidates that require mechanical verification via datasheet comparison.
Best replacement path
Source a 1x5 single-row male header with 2.54mm pitch and straight, through-hole pins. Compare datasheets to match pin lengths and housing dimensions.
Main risk
The primary risk is mechanical incompatibility. Different pin lengths can affect mating connection height, and housing size variations can cause interference on the PCB.
