311-83-139-41-001101

Headers, Receptacles, Female Sockets Overview

The Preci-Dip 311-83-139-41-001101 is a board-to-board and mezzanine connector designed for high-density electronic interconnections. This specific component features 39 positions arranged in a single row with a 0.100-inch (2.54mm) mating pitch. It utilizes female socket contacts made of beryllium copper, finished with gold plating on the mating interface and tin on the solder tail. The connector employs a push-pull locking mechanism to ensure secure attachment between boards. Designed for through-hole mounting, it operates within a temperature range of -55°C to 125°C and meets UL94 V-0 flammability standards.

Headers, Receptacles, Female Sockets Feature Summary

• Push-pull locking system for secure board-to-board retention
• Gold-plated beryllium copper female sockets for reliable signal transmission
• Single-row straight configuration optimized for space-constrained layouts

Headers, Receptacles, Female Sockets Applications

• High-density server backplane interconnects
• Industrial control module stacking
• Telecommunications equipment internal connections

Headers, Receptacles, Female Sockets Procurement Notes

Verify the exact contact count matches the '139' series designation during procurement. Confirm that the push-pull latching style aligns with the mechanical constraints of the assembly enclosure. Ensure the supplier provides documentation confirming RoHS compliance and material traceability for the beryllium copper contacts prior to finalizing orders.

Headers, Receptacles, Female Sockets Selection Notes

Select this model when a single-row, 2.54mm pitch female connector with positive locking is required. Compare against the 316 series if a non-locking variant is acceptable, or the 323 series if different insulation heights are needed. Verify that the 39-position length fits the available PCB real estate without obstructing adjacent components.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the Preci-Dip 311 series, which specializes in board-to-board connectors featuring push-pull latching mechanisms. The series is characterized by its robust mechanical retention and use of beryllium copper contacts. The 311-83-139-41-001101 represents a specific configuration within this family, distinguished by its 39-contact count and standard through-hole termination style.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes include other 39-position, 2.54mm pitch female connectors from Preci-Dip's 311 series with identical latching mechanisms. Cross-referencing with the 316 series may be possible if locking features are not strictly required, provided mechanical dimensions and electrical ratings remain compatible.
