Headers, Receptacles, Female Sockets Overview

The Preci-Dip 310-87-121-01-754101 is a single-row socket connector featuring 21 positions with a 0.100 inch (2.54mm) mating pitch. Designed for through-hole mounting, it utilizes copper beryllium contacts with flash gold plating on the mating surface and tin on the tail. The housing is constructed from glass-filled PCT polyester in black, rated UL94 V-0. It supports a current rating of 3A and operates within a temperature range of -55°C to 125°C.

Headers, Receptacles, Female Sockets Feature Summary

• Flash gold contact plating ensures reliable signal transmission
• Glass-filled PCT insulation provides high thermal stability

Headers, Receptacles, Female Sockets Applications

• Industrial control system circuit boards
• Consumer electronics internal connections
• Communication equipment backplanes

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific pin count matches the '121' code in the part number to ensure correct positioning. Confirm that the flash gold plating thickness meets the application's wear requirements. Check that the through-hole solder tail configuration aligns with the PCB fabrication capabilities. Ensure the operating environment temperature remains within the specified -55°C to 125°C range for optimal performance.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a single-row 2.54mm pitch socket is required for high-reliability applications. The copper beryllium alloy offers superior spring properties compared to standard brass. The UL94 V-0 rated insulation is suitable for environments requiring flame resistance. Consider the 3A current rating against the total load of the connected circuitry to prevent overheating during continuous operation.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the Preci-Dip 310 series of SIP sockets. It is designed as a complementary counterpart to header connectors within the same series. The standardized dimensions allow for consistent assembly across various product lines. The series is known for robust mechanical retention and stable electrical characteristics in dense packaging scenarios.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes include other 21-position, 2.54mm pitch single-row sockets with identical mounting styles. Verify that alternative parts maintain the same flash gold plating specification and UL94 V-0 insulation rating. Cross-reference the overall height and standoff dimensions to ensure compatibility with existing enclosure constraints.
