EJH-120-01-F-D-SM-LC-01

Headers, Male Pins Overview

The Samtec EJH-120-01-F-D-SM-LC-01 is a surface mount header connector featuring a 0.100 inch (2.54 mm) pitch and two rows of contacts, totaling 40 positions. It utilizes phosphor bronze terminals with selective gold plating on the mating interface and tin termination surfaces. The housing is constructed from black liquid crystal polymer (LCP), providing a robust insulation height of 0.500 inches. Designed for board-to-cable or wire applications, this component includes an integrated latch and eject mechanism for secure retention. It operates within a temperature range of -55°C to 125°C and carries a current rating of 3A per contact.

Headers, Male Pins Feature Summary

• Integrates a rugged latch and eject mechanism for secure board retention and simplified removal.
• Features selective gold plating on mating contacts to ensure reliable signal transmission.
• Constructed with liquid crystal polymer insulation for high thermal stability and mechanical strength.
• Includes polarization notches to prevent incorrect insertion during assembly.

Headers, Male Pins Applications

• Board-to-cable interconnections in industrial control systems
• High-density signal routing in telecommunications equipment
• Surface mount integration in automotive electronic modules
• Ruggedized connections for aerospace and defense instrumentation

Headers, Male Pins Procurement Notes

Verify that the specific suffix LC indicates the inclusion of board lock features, as configuration codes define functional variations. Confirm RoHS compliance status and moisture sensitivity level requirements against project specifications. Ensure mating connectors match the 0.100-inch pitch and double-row configuration. Validate surface mount footprint dimensions against the official CAD model prior to PCB layout finalization.

Headers, Male Pins Selection Notes

Select this component when surface mount technology is required for high-reliability interconnects. The dual-row arrangement supports higher pin counts within a compact footprint compared to single-row alternatives. The ejector feature is critical for maintenance-heavy environments requiring frequent connector replacement. Ensure the application environment stays within the specified operating temperature range for optimal performance.

Headers, Male Pins Part Context

This part belongs to the EJH series of .100" shrouded IDC ejector headers manufactured by Samtec Inc. The series offers various mounting styles including through-hole, right-angle, and surface mount options. Common pin counts range from 10 to 50, allowing for flexible design configurations across different industry standards and application densities.

Headers, Male Pins Replacement Considerations

Direct substitutes include other EJH series variants with matching pitch and row count. Verify equivalent latch mechanisms and plating specifications before substitution. Cross-reference mating connectors to ensure compatibility with the 0.100-inch square post terminal strip.
