Key Features
- 72-position dual-row 1.27 mm pitch SMT socket provides very high pin-count fine-pitch board-to-board interconnect in a compact surface-mount footprint
- High-reliability rating with gold-plated contacts supporting 500 mating cycles and contact resistance below 30 mΩ for demanding repeated-swap environments
- Low-profile SMT design enables tight PCB stack heights for layered mezzanine module assemblies in space-constrained systems
Applications
The SFM-136-T2-S-D-A-K is used in FPGA mezzanine carrier boards, high-speed SerDes interface modules, and multi-processor embedded computing platforms where a 72-position 1.27 mm pitch dual-row socket provides the high pin-count connectivity needed for parallel data buses, power distribution, and control signals in a single fine-pitch connector. It is also found in military and aerospace avionics test assemblies requiring 500-cycle-rated gold contacts operating across -55°C to 125°C for long service life.

Frequently Asked Questions
How many pins does SFM-136-T2-S-D-A-K have, and how are they arranged?
The SFM-136-T2-S-D-A-K provides 72 pins in a dual-row (2×36) configuration with 1.27 mm (0.050 inch) pitch, spanning approximately 46.99 mm in length and 2.54 mm in width, making it one of the higher pin-count options in the SFM series for demanding FPGA and data-routing mezzanine applications.
What mating cycle rating does SFM-136-T2-S-D-A-K achieve, and how does that compare to standard connectors?
The SFM-136-T2-S-D-A-K is rated for 500 mating cycles while maintaining contact resistance below 30 mΩ, which is significantly higher than standard 50-cycle-rated economy connectors and supports applications like field-replaceable FPGA modules, rotating daughterboard test fixtures, and modular radar signal processors that require frequent board removal and reinsertion.
Which SAMTEC header series mates with SFM-136-T2-S-D-A-K for a controlled-impedance backplane design?
The SFM-136-T2-S-D-A-K mates with SAMTEC SHF and SFM dual-row headers sharing the 1.27 mm pitch, and designers can select stack heights from 4 mm to over 20 mm to accommodate component clearance on both PCBs, with certain SHF variants offering controlled 50 Ω or 100 Ω differential impedance for high-speed LVDS or PCIe signals up to several gigabits per second.
Can SFM-136-T2-S-D-A-K survive the temperature extremes seen in military avionics applications?
Yes, the SFM-136-T2-S-D-A-K is rated from -55°C to 125°C, which covers MIL-STD-810 temperature cycling requirements, making it suitable for airborne electronics boxes, shipboard instrument panels, and ground-vehicle embedded computers that experience -40°C cold-soak at altitude and 85°C to 125°C peak junction temperatures during sustained high-power operation.
