Engineering Selection Recommendations

Both the DF3-11P-2DSA(01) and DF3A-11P-2DSA are Active status products manufactured by Hirose Electric Co Ltd and are RoHS Compliant with UL94 V-0 flammability certification. Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no special handling requirements during storage or assembly.

The primary difference between these parts is the contact finish specification. The DF3-11P-2DSA features gold plating (8.00µin thickness), while the DF3A-11P-2DSA uses tin plating (39.4µin thickness). Both finishes provide adequate corrosion resistance and electrical conductivity for the 3A current rating and -55°C to 105°C operating temperature range.

Selection between these parts should be based on application-specific requirements regarding contact finish performance, cost considerations, and existing inventory availability. Both parts are functionally equivalent for board-to-board and cable connector applications requiring 11-position, 2.00mm pitch through-hole headers with push-pull fastening.

Frequently Asked Questions (FAQ)

Q: Can DF3A-11P-2DSA be used as a direct replacement for DF3-11P-2DSA(01)?

A: Yes. Both parts share identical mechanical dimensions, electrical ratings, and connector interface specifications. The contact finish difference (gold versus tin) does not affect mating compatibility or mechanical fit.

Q: What is the significance of the contact finish difference between these parts?

A: Contact finish affects corrosion resistance and long-term contact reliability under specific environmental conditions. Gold plating provides superior corrosion resistance in harsh environments, while tin plating is suitable for standard industrial applications. Both finishes meet the 3A current rating and operating temperature range specified for this connector series.

Q: Are both parts suitable for the same PCB footprint?

A: Yes. Both the DF3-11P-2DSA(01) and DF3A-11P-2DSA have identical through-hole mounting dimensions, insulation height, and contact positioning. They are mechanically interchangeable on the same PCB layout.

Q: Do these parts require different handling or storage procedures?

A: No. Both parts carry Moisture Sensitivity Level 1 (Unlimited), meaning they do not require special moisture control during storage, handling, or assembly.

Q: What is the mating connector for these header parts?

A: These are header connectors designed for board-to-board or cable applications. The mating connector must be a receptacle connector compatible with the DF3 series, featuring 11 positions and 2.00mm pitch.
