EJH-120-02-F-D-SM-LC-25

Headers, Male Pins Overview

Samtec EJH-120-02-F-D-SM-LC-25 is a surface mount header from the EJH series, featuring a 0.100 inch (2.54 mm) pitch and double-row configuration with 40 positions. It utilizes phosphor bronze contacts with gold flash over nickel plating for mating surfaces and tin termination finishes. The connector employs liquid crystal polymer insulation and includes a polarization notch for orientation. Designed for IDC applications, it supports right-angle or straight mounting styles and offers rugged retention features suitable for board-to-cable interconnections.

Headers, Male Pins Procurement Notes

Verify the specific suffix LC-25 against official Samtec documentation to confirm length and packaging variations. Ensure compatibility with mating IDC sockets such as IDSD or HCSD series. Confirm RoHS compliance status and moisture sensitivity level requirements for your manufacturing process before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a shrouded, polarized surface mount header with IDC capabilities is required. The double-row layout maximizes pin density while maintaining standard 2.54 mm spacing. Consider the rugged retention features if vibration resistance is critical. Verify that the mating cable assembly matches the specified pitch and row count for proper engagement.

Headers, Male Pins Part Context

The EJH series represents Samtec's .100 inch shrouded IDC ejector headers. This model belongs to a family offering various mounting styles including through-hole and surface mount options. The EJH-120 variant specifically denotes a 40-position double-row configuration within the broader product line designed for robust electronic interconnects.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other Samtec EJH series headers with matching pitch and position counts. Mating components such as IDSD slim body double-row IDC socket assemblies are officially documented partners. Verify mechanical dimensions and electrical ratings before substituting with generic equivalents.
