Engineering Selection Recommendations

The DF14-5P-1.25H(35) is the direct equivalent for the obsolete DF14-5P-1.25H(24). Both parts share identical electrical ratings, mechanical dimensions, and functional specifications within the DF14 series. The primary distinction is product status: the DF14-5P-1.25H(24) is obsolete, while the DF14-5P-1.25H(35) maintains active production status.

The DF14-5P-1.25H(35) carries ROHS3 compliance, which supersedes the RoHS compliance designation of the original part, providing enhanced regulatory alignment for current manufacturing standards. Contact finish specifications differ slightly (Tin versus Tin-Copper), but both finishes meet the same electrical and mechanical performance requirements for this connector class.

For new designs and production continuity, the DF14-5P-1.25H(35) is the appropriate selection. Existing inventory of the DF14-5P-1.25H(24) may be utilized in current production without functional impact, provided supply chain transition planning is implemented.

Frequently Asked Questions (FAQ)

Q: Can the DF14-5P-1.25H(35) be used as a direct replacement for the DF14-5P-1.25H(24) in existing designs?

A: Yes. Both parts are mechanically and electrically identical across all critical parameters including pitch, position count, mounting type, electrical ratings, and operating temperature range. PCB layouts and mating connector specifications require no modification.

Q: What is the significance of the different contact finish specifications?

A: The DF14-5P-1.25H(24) features Tin-Copper contact finish, while the DF14-5P-1.25H(35) uses Tin finish. Both finishes provide equivalent electrical conductivity and corrosion resistance for this connector application. The finish thickness remains identical at 39.4µin (1.00µm) for both parts.

Q: Why is the DF14-5P-1.25H(24) classified as obsolete?

A: Obsolescence typically reflects manufacturer discontinuation of production. The DF14-5P-1.25H(35) represents the active continuation of this connector family within the DF14 series.
