Key Features
- 74-position dual-row SMT socket strip at 0.050" (1.27 mm) pitch for very high-density board-to-board module connections
- High-reliability construction with gold contact finish for low contact resistance and extended mating cycle life
- Tape-and-reel (TR) format for fully automated SMT pick-and-place assembly in volume production environments
Applications
The SFM-137-02-FM-D-A-P-TR is engineered for high-reliability, high-density surface mount interconnects in FPGA mezzanine modules, embedded computing daughter cards, and advanced instrumentation platforms. Its 74-position dual-row socket strip at 0.050" pitch accommodates 148 total contacts in a fine-pitch SMT footprint, enabling complex signal routing in space-constrained designs. The gold contact finish and high-reliability rating make this connector suitable for mil-aero, medical, and industrial applications where connection integrity is critical.

Frequently Asked Questions
What is the total contact count and pitch of the SFM-137-02-FM-D-A-P-TR socket strip?
The SFM-137-02-FM-D-A-P-TR provides 148 total contacts in a 74-position dual-row configuration at 0.050" (1.27 mm) pitch. This fine pitch allows designers to route 148 signals through a surface mount socket in a footprint far smaller than standard 0.100" pitch connectors, making it essential for compact FPGA mezzanine and module-to-board applications.
How does the SFM-137-02-FM-D-A-P-TR perform in high-reliability applications such as industrial or aerospace designs?
Rated as a high-reliability connector, the SFM-137-02-FM-D-A-P-TR uses gold-plated contacts to ensure stable contact resistance below 20 milliohms across its 148-contact array, even under temperature cycling from -55°C to +125°C. The gold finish resists oxidation and fretting corrosion, maintaining electrical continuity over hundreds of mating cycles in demanding industrial, aerospace, and high-cycle-life applications.
Can the SFM-137-02-FM-D-A-P-TR be used as a socket for SAMTEC SFM-series pin headers, and what pitch compatibility is required?
Yes, the SFM-137-02-FM-D-A-P-TR mates with SAMTEC SFM-series and compatible 0.050" pitch dual-row pin headers. The mating connector must also be a 0.050" (1.27 mm) pitch dual-row male header with 74 positions to match the 148-contact socket array. Mismatched pitch, such as 0.100" headers, will not physically engage the fine-pitch contacts and should be avoided.
