What are the key features of SFM-137-L2-ZZ-D-A-K-TR?
- 74-position dual-row (2x37) socket strip with 0.050" (1.27 mm) pitch enabling very high contact density in SMT board-to-board stacking
- Tape-and-reel (TR) packaging supporting automated high-volume pick-and-place assembly with precise placement on 1.27 mm pitch SMT pads
- High reliability SAMTEC SFM series construction rated for demanding mating cycles in aerospace, defense, and industrial electronics applications
What is SFM-137-L2-ZZ-D-A-K-TR used for?
The SFM-137-L2-ZZ-D-A-K-TR is designed for high-density board-to-board and mezzanine connector applications in FPGA modules, embedded computing platforms, and DSP boards requiring 74 simultaneous signal connections at 0.050" pitch. Its surface mount configuration and tape-and-reel packaging make it well-suited to high-volume automated production of telecommunications line cards and industrial data acquisition modules. Defense and aerospace electronics engineers also specify this socket strip for avionics and radar systems where compactness and reliability over temperature cycles from -55°C to +125°C are essential.

Frequently Asked Questions
What is the total contact count and row configuration of the SFM-137-L2-ZZ-D-A-K-TR socket strip?
The SFM-137-L2-ZZ-D-A-K-TR is a 74-position dual-row (2x37) socket strip with a 0.050" (1.27 mm) pitch, providing 74 individual contacts in a compact surface mount package. This high-density configuration supports simultaneous connection of up to 74 signals between mated boards, making it suitable for FPGA mezzanine modules, high-speed data buses, and complex processor interface boards.
How does the 0.050" pitch of SFM-137-L2-ZZ-D-A-K-TR compare to standard 0.100" pitch connectors for high-speed signal integrity?
At 0.050" (1.27 mm) pitch, the SFM-137-L2-ZZ-D-A-K-TR provides twice the contact density of a standard 0.100" (2.54 mm) pitch connector in the same board length, supporting routing of high-speed differential pairs and parallel buses in approximately half the footprint. This reduced pitch is critical for FPGA I/O expansion cards and DSP interfaces operating at signal frequencies exceeding 500 MHz where minimizing stub length and trace length matching within 74-contact arrays is essential.
For a radar or avionics board procurement, what qualifications or operating specifications does the SFM-137-L2-ZZ-D-A-K-TR meet?
SAMTEC SFM series connectors including the SFM-137-L2-ZZ-D-A-K-TR are designed for high reliability applications with gold-plated contacts and rated operating temperatures of -55°C to +125°C, meeting requirements for aerospace and defense programs subject to MIL-spec environmental conditions. The high-cycle mating durability exceeds 200 insertion/withdrawal cycles, and the RoHS-compliant construction supports modern defense procurement requirements for lead-free assemblies in avionics and radar signal processing boards.
