DF3-2S-2DSA(25)

Headers, Receptacles, Female Sockets Overview

The DF3-2S-2DSA(25) is a 2-position socket connector from the Hirose DF3 series, designed for board-to-board or cable applications. It features a 2.00mm pitch and utilizes through-hole solder termination. The housing is constructed from black polyamide (PA) nylon with UL94 V-0 flammability rating. Contacts are made of phosphor bronze with square shape and tin plating, providing a 2.00µm thickness. Rated at 3A current and 30VAC voltage, it operates within a temperature range of -30°C to 85°C. The friction lock style ensures secure mating.

Headers, Receptacles, Female Sockets Feature Summary

• Friction lock mechanism provides secure connection without additional hardware
• Tin-plated phosphor bronze contacts ensure reliable signal transmission
• Black polyamide insulation offers high thermal stability and flame resistance

Headers, Receptacles, Female Sockets Applications

• Board-to-board interconnections in compact electronic modules
• Cable-to-board connections requiring through-hole mounting
• Industrial control systems utilizing standard signal interfaces

Headers, Receptacles, Female Sockets Procurement Notes

Verify that the specific suffix (25) matches the required stacking height specifications for your assembly. Confirm that the through-hole pin dimensions align with your PCB drill patterns. Ensure compatibility with the corresponding DF3 series male header for proper mating engagement. Check material certifications if required by your industry standards.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a low-profile, 2-position socket is needed for direct PCB mounting. The 2.00mm pitch allows for dense circuit layouts while maintaining adequate spacing. The tin finish supports standard lead-free soldering processes. Consider the 30VAC rating for low-voltage signal applications rather than high-power distribution.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the DF3 series, a line of connectors known for small size and high reliability. The series includes various positions and termination styles. The DF3-2S variant specifically denotes a 2-position female receptacle. The DSA suffix typically indicates specific packaging or tape-and-reel configurations in some contexts, though tube packaging is also listed.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes include other 2-position, 2.00mm pitch sockets from the same manufacturer. Verify mechanical dimensions and electrical ratings before swapping. Generic equivalents may lack the specific friction lock feature or UL certification. Cross-reference with Hirose's official replacement guide for discontinued variants.
