Applications
The SFM-142-T2-FM-D is designed for high-density board-to-board socket connections in telecommunications equipment, networking infrastructure, and industrial embedded computing systems. Its 84-position, 0.050" pitch SMT design enables mezzanine card attachment, daughter-board stacking, and backplane socket interfaces where high signal count and compact footprint are both required. Defense electronics and data acquisition systems also use this socket strip for its high-reliability contact design and repeatable mating performance.

Frequently Asked Questions
What is the position count, pitch, and mounting style of the SFM-142-T2-FM-D socket strip?
The SFM-142-T2-FM-D is an 84-position dual-row socket strip with a 0.050" (1.27 mm) pitch and a surface-mount (SMT) footprint. The dual-row layout distributes 84 contacts across two parallel rows, which reduces the connector's overall board length compared to a single-row design and allows for high-density signal routing in compact PCB layouts found in telecom and embedded computing platforms.
How does the SFM-142-T2-FM-D achieve high reliability across repeated mating cycles?
The SFM-142-T2-FM-D uses precision-formed contacts with gold plating and a spring-beam design engineered to maintain consistent normal force over thousands of insertions and extractions. This keeps contact resistance below 20 milliohms throughout the connector's service life and prevents intermittent opens caused by contact wear or oxidation. The high-reliability rating makes it suitable for field-replaceable modules and hot-swappable boards in networking and industrial applications.
Which PCB assembly process supports the SFM-142-T2-FM-D, and what reflow temperature does it tolerate?
The SFM-142-T2-FM-D is a surface-mount component compatible with standard SMT reflow soldering up to 260°C per IPC-J-STD-020. It can be placed using automated pick-and-place equipment and soldered in a single reflow pass alongside other SMT devices, simplifying board assembly. This compatibility with high-volume SMT processes makes it cost-effective for large production runs in telecom and computing hardware manufacturing.
What header connector family mates with the SFM-142-T2-FM-D in a board-to-board stack?
The SFM-142-T2-FM-D is designed to mate with SAMTEC's matching SFM-series headers or compatible 0.050" pitch dual-row pin headers, creating a reliable 84-position board-to-board interconnect with a mated height determined by the header stack height selection. This pairing supports stack heights from approximately 1.5 mm to over 15 mm, allowing system designers to set board separation based on component clearance requirements in multi-board enclosures and mezzanine card assemblies.
