EHT-125-01-S-D-SM-SR-LC-50

Headers, Male Pins Overview

The EHT-125-01-S-D-SM-SR-LC-50 is a rectangular header assembly from the Samtec EHT series, designed for board-to-cable or wire connections. It features 50 positions arranged in two rows with a 2.00 mm (0.079 inch) pitch. The connector utilizes surface mount termination and includes an ejector mechanism for secure mating. Contacts are made of phosphor bronze with gold plating over nickel on the mating interface and matte tin on the tail. The housing is constructed from black liquid crystal polymer (LCP), rated for operation between -55°C and 125°C.

Headers, Male Pins Feature Summary

• Ejector header system with locking mechanism for reliable connection retention
• Surface mount termination style for automated PCB assembly
• Four-wall shrouded design providing environmental protection and alignment
• Gold-plated contacts ensuring low contact resistance and corrosion resistance

Headers, Male Pins Applications

• High-density board-to-board interconnects requiring vertical stacking
• Wire-to-board connections in compact electronic modules
• Industrial control systems needing robust mechanical retention
• Telecommunications equipment utilizing high-reliability power or signal links

Headers, Male Pins Procurement Notes

Verify the specific suffix codes against official Samtec documentation to confirm the exact configuration of the ejector latch and lead frame material. Ensure that the surface mount pad layout matches the target PCB design guidelines provided in the manufacturer's drawing. Confirm RoHS3 compliance status if required by regional regulations. Cross-reference the part number with the latest catalog to avoid discrepancies in updated series revisions.

Headers, Male Pins Selection Notes

Select this component when a surface mount solution with integrated ejector functionality is required for 2mm pitch applications. Consider the thermal profile limits of the LCP insulation during soldering processes. Evaluate the available stack height options within the EHT series if vertical clearance constraints exist. Verify that the current rating requirements align with the contact specifications for the intended application environment.

Headers, Male Pins Part Context

This part belongs to the EHT (Ejector Header Terminal) series by Samtec Inc., which specializes in rugged, high-reliability interconnect solutions. The series is characterized by its unique ejector feature that facilitates easy removal of the connector from the mating receptacle without damaging the pins. It serves as a critical link in systems demanding durable, repeatable connections in challenging environments.

Headers, Male Pins Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Alternative connectors from other manufacturers may require significant redesign of the PCB footprint and mechanical mounting structure due to differences in pin spacing, shroud dimensions, and ejector mechanisms.
