Engineering Selection Recommendations

The DF13C-11P-1.25V(21) is the direct substitute for the obsolete DF13B-11P-1.25V(21). Both parts maintain identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: DF13B is obsolete while DF13C is active, with significantly higher inventory availability (2496 units versus 701 units). Both parts carry RoHS compliance and UL94 V-0 flammability certification. The DF13C is supplied in Tape & Reel packaging, which is standard for production environments. Selection of DF13C-11P-1.25V(21) ensures long-term supply chain continuity and compliance with current component lifecycle management practices.

Frequently Asked Questions (FAQ)

Q: Are DF13B-11P-1.25V(21) and DF13C-11P-1.25V(21) electrically interchangeable?

A: Yes. Both parts share identical electrical ratings: 1A current rating, 150V voltage rating, and -35°C to 85°C operating temperature range. Mating pitch, contact material, and contact finish specifications are identical.

Q: Are these parts mechanically interchangeable?

A: Yes. Both parts feature identical mechanical specifications: 11-position header, 1.25mm pitch, surface mount configuration, shrouded 3-wall design, solder termination, and 5.8mm mated stacking height. PCB footprints and mating interface dimensions are identical.

Q: What is the difference between DF13B and DF13C?

A: The primary difference is product status. DF13B is obsolete, while DF13C is active. DF13C includes solder retention feature specification, while DF13B lists both board guide and solder retention. Both parts are functionally equivalent for connector applications.

Q: Why should I use DF13C instead of DF13B?

A: DF13C is the active product with superior inventory availability (2496 units in stock). Using the active part ensures design longevity and eliminates obsolescence risk. DF13C is supplied in standard Tape & Reel packaging suitable for automated assembly.

Q: Are there any compliance differences between these parts?

A: No. Both parts are RoHS compliant, carry UL94 V-0 flammability rating, and share identical ECCN (EAR99) and HTSUS classifications. Moisture sensitivity level is 1 (Unlimited) for both parts.

Q: Can I use these connectors in high-temperature applications?

A: Both parts operate within -35°C to 85°C. Applications requiring operation outside this range require alternative connector selection.
