• Identical MSL rating and environmental classification

Frequently Asked Questions (FAQ)

Q: Can 1618464 be used as a direct replacement for 1618254 in existing designs?

A: Yes. Both parts share identical contact size (1.0mm), termination method (crimp), series designation (ST), and MSL rating. The substitute part's expanded wire gauge range is backward compatible with the original specification.

Q: What is the difference in contact material specification?

A: The original part specifies Copper Zinc Alloy material. The substitute part does not list material specification in the provided data. Verification of material compatibility should be conducted through Phoenix Contact technical documentation if material composition is critical to the application.

Q: Does the packaging difference affect compatibility?

A: Packaging format (bulk versus unspecified) does not affect electrical or mechanical compatibility. Packaging selection depends on procurement and inventory management requirements.

Q: Are there compliance differences between the two parts?

A: The substitute part carries ROHS3 compliance, which exceeds the original RoHS Compliant designation. The substitute also indicates REACH Affected status. Both parts maintain identical ECCN and HTSUS classifications.

Q: Is the expanded wire gauge range of 1618464 a concern?

A: No. The substitute part supports 0.25 ~ 1.0mm², which fully encompasses the original 0.5 ~ 1.0mm² range. This expansion provides additional application flexibility without compromising compatibility with existing designs.
