FTSH-125-04-L-DH

Headers, Male Pins Overview

The FTSH-125-04-L-DH is a high-reliability header strip manufactured by Samtec Inc., designed for board-to-board interconnections. This component features a dual-row configuration with 50 contacts arranged in a 2x25 layout. It utilizes a 0.050-inch (1.27mm) pitch and employs surface mount right-angle termination technology. The connector is constructed with phosphor bronze contacts finished with selective gold plating on the mating area and matte tin on the tails, ensuring durability and reliable electrical performance.

Headers, Male Pins Procurement Notes

Verify the specific suffix codes against official Samtec documentation to confirm exact termination style, plating thickness, and packaging format. Ensure the selected variant matches the required mechanical orientation and contact count for the target PCB footprint. Cross-reference the RoHS compliance status and material specifications with current regulatory requirements before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when high mating cycle endurance and strict adherence to military-grade testing standards are required. Evaluate the need for polarized configurations to ensure correct assembly alignment. Consider the surface mount right-angle form factor for space-constrained vertical stacking applications. Confirm that the 1.27mm pitch aligns with the system's density requirements and signal integrity needs.

Headers, Male Pins Part Context

This part belongs to the FTSH series of high-reliability header strips from Samtec. The series offers extensive configurability, including various post heights, row orientations, and termination technologies. It is engineered for demanding environments, providing solutions that meet or exceed MIL-DTL-55302 standards while supporting high-speed data transmission protocols.

Headers, Male Pins Replacement Considerations

Direct substitutes within the FTSH series include variants with different contact counts or termination styles, such as FTSH-125-04-L-DH-TR for tape-and-reel packaging. Verify mechanical compatibility and pinout definitions before substituting. Generic connectors may not offer the same level of mating cycle durability or environmental qualification.
