EHT-125-01-L-D-SM-SR-P

Headers, Male Pins Overview

The EHT-125-01-L-D-SM-SR-P is a 50-position board connector from the Samtec EHT series. It features a dual row of male pins with a 0.079-inch (2.00mm) pitch. Designed for surface mount installation, it utilizes a latch and eject mechanism for secure mating. The contacts are made of phosphor bronze with gold plating over nickel in the contact area and matte tin on the tails. The insulator is black liquid crystal polymer (LCP).

Headers, Male Pins Feature Summary

• Features a four-wall shrouded design to ensure precise alignment during board-to-cable or wire connections.
• Incorporates a latch and eject system that allows for quick and secure engagement and disengagement without tools.
• Constructed with liquid crystal polymer insulation to provide high thermal stability and flame resistance.
• Utilizes square pin sockets to maintain consistent contact pressure and reliable signal transmission.

Headers, Male Pins Applications

• Board-to-cable interconnections requiring robust mechanical retention.
• Wire-to-board assemblies where space constraints necessitate a low-profile surface mount header.
• Industrial control systems demanding high reliability under varying environmental conditions.
• Consumer electronics manufacturing utilizing automated pick-and-place assembly processes.

Headers, Male Pins Procurement Notes

Verify the specific suffix codes against official Samtec documentation to confirm exact plating specifications and reel packaging requirements. Ensure compatibility with mating cable assemblies regarding pitch and housing dimensions. Confirm RoHS compliance status and moisture sensitivity level ratings prior to integration into production lines to prevent soldering defects.

Headers, Male Pins Selection Notes

Select this component when a surface mount solution with integrated latching is required for 2.00mm pitch applications. Consider the mechanical strength of the latch mechanism for repeated insertion cycles. Evaluate the thermal profile capabilities of the LCP material against peak reflow temperatures. Compare physical envelope dimensions against available PCB real estate to ensure proper fitment alongside adjacent components.

Headers, Male Pins Part Context

This part belongs to the EHT series of shrouded headers designed for high-reliability interconnects. The series offers various mounting styles and contact configurations to support diverse board-to-cable needs. The EHT-125-01-L-D-SM-SR-P specifically addresses applications needing surface mount convenience combined with secure mechanical locking features for vibration-prone environments.

Headers, Male Pins Replacement Considerations

Direct substitutes may include other Samtec EHT series variants with matching pitch and position counts. Verify equivalent latch mechanisms and shroud heights when cross-referencing with competitor products. Ensure alternative parts meet the same UL recognition and environmental compliance standards.
