Frequently Asked Questions (FAQ)

Q: Are DF14-25S-1.25C and DF14-25S-1.25C(10) electrically identical?

A: Yes. Both parts are 25-position receptacle housings with identical pitch (1.25mm), contact type (female socket), termination method (crimp), and operating temperature range (-35°C to 85°C).

Q: What does the "(10)" designation indicate in DF14-25S-1.25C(10)?

A: The "(10)" suffix indicates a product revision or variant within the DF14 series. In this case, it represents an active production version with updated compliance certifications (ROHS3).

Q: Can I use DF14-25S-1.25C(10) as a direct replacement in existing assemblies?

A: Yes. The substitute part maintains identical mechanical and electrical specifications, including housing dimensions, contact configuration, and mounting type. No PCB or assembly modifications are required.

Q: What is the difference in packaging between the two parts?

A: The original DF14-25S-1.25C uses standard packaging, while DF14-25S-1.25C(10) is available in bulk packaging. Bulk packaging is suitable for high-volume manufacturing environments.

Q: Are there any compliance differences I should consider?

A: DF14-25S-1.25C(10) carries ROHS3 certification, which supersedes the RoHS Compliant status of the original part. Both meet environmental and regulatory requirements for their respective product lifecycles.

Q: Why is the original DF14-25S-1.25C marked as obsolete?

A: Product obsolescence typically occurs when a manufacturer transitions to newer product revisions or variants. DF14-25S-1.25C(10) represents the active continuation of this connector housing line.
