FTSH-125-01-F-DV-EJ-K-A

Headers, Male Pins Overview

The FTSH-125-01-F-DV-EJ-K-A is a high-reliability header strip from the Samtec FTSH series, designed for board-to-board interconnections. It features a 1.27mm (0.050 inch) pitch with 50 positions arranged in two rows. The connector utilizes surface mount termination and includes latch lock/eject hooks for secure fastening. Contact materials consist of phosphor bronze with gold plating on mating surfaces and tin on tails. Rated at 3.4A per contact, it operates within a temperature range of -55°C to +125°C. The housing is made of black liquid crystal polymer (LCP) with UL94 V-0 flammability rating.

Headers, Male Pins Feature Summary

• Configurable micro header design supporting various post heights and termination technologies including surface mount and through-hole options.
• Integrated latch lock and eject hook mechanism ensures secure connection and facilitates easy removal during maintenance or replacement.
• Capable of meeting or exceeding MIL-DTL-55302 testing standards, suitable for high mating cycle applications and severe environments.

Headers, Male Pins Applications

• High reliability board-to-board interconnections requiring robust mechanical retention
• Applications subject to severe environmental conditions and high mating cycles
• Systems requiring polarized or keyed installation to prevent incorrect insertion

Headers, Male Pins Procurement Notes

Verify that the specific ordering suffix matches the required termination type, orientation, and contact plating thickness. Confirm that the package quantity aligns with production needs without referencing prohibited terms. Ensure compatibility with mating socket specifications regarding height and keying features before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when board-to-board connections demand high durability and reliable signal integrity under harsh conditions. The surface mount configuration suits automated assembly processes. Consider the eject hook feature if frequent maintenance access is required. Validate thermal performance against system operating temperatures and ensure PCB layout accommodates the specified tail dimensions.

Headers, Male Pins Part Context

This part belongs to the FTSH series of high-reliability header strips manufactured by Samtec Inc. The series offers extensive configurability, allowing for mixed technology terminations and various row configurations. It is engineered for demanding applications where standard connectors may fail due to vibration, thermal cycling, or repeated mating stress.

Headers, Male Pins Replacement Considerations

Direct substitutes within the same family include FTSH-125-01-F-DV-EJ-K-P-TR and FTSH-125-01-L-DV-EJ-K-A-TR. Verify that alternative parts match the exact pin count, pitch, and mounting style. Cross-reference mechanical drawings to ensure footprint compatibility and confirm electrical ratings are equivalent for safe operation.
