DF3-3S-2DSA(20)

Headers, Receptacles, Female Sockets Overview

The DF3-3S-2DSA(20) is a 3-position socket connector from the Hirose DF3 series, designed for board-to-board or cable applications. It features a 2.00mm (0.079 inch) mating pitch and utilizes through-hole mounting with solder pin termination. The contacts are made of phosphor bronze with tin plating on both the mating interface and posts. Rated for 3A current and 30VAC voltage, it operates within a temperature range of -30°C to 85°C. The housing is black polyamide (PA/nylon) with UL94 V-0 flammability rating. Mated stacking heights are specified at 6.6mm and 7.5mm.

Headers, Receptacles, Female Sockets Procurement Notes

Verify component authenticity against official Hirose documentation due to potential counterfeit risks. Confirm that the specific suffix (20) matches required specifications, as variations exist within the DF3 series. Check for end-of-life status or obsolescence notices prior to procurement. Ensure compatibility with corresponding male headers such as DF3-3P variants. Validate environmental ratings against application requirements.

Headers, Receptacles, Female Sockets Selection Notes

Select this model when a 3-position female receptacle with 2mm pitch is required for through-hole mounting. Consider the 6.6mm or 7.5mm stacking height depending on board thickness. Verify that the tin-plated contacts meet corrosion resistance needs. Ensure the 3A current rating suffices for the circuit load. Compare against alternative positions if more circuits are needed.
