Frequently Asked Questions
What is the total position count and row arrangement of the SFM-149-T2-SM-D-A-K, and what pitch does it use?
The SFM-149-T2-SM-D-A-K provides 98 positions arranged in a dual-row configuration with 49 pins per row at a 0.050" (1.27 mm) pitch. This high-density pitch packs twice the signal count of standard 0.100" connectors in the same board length, making it highly efficient for FPGA I/O expansion, high-speed parallel bus routing, and mezzanine card interfaces where board space is limited.
How does the 0.050" pitch of the SFM-149-T2-SM-D-A-K compare to standard 0.100" connectors for PCB routing density?
The 0.050" (1.27 mm) pitch of the SFM-149-T2-SM-D-A-K provides double the pin density of standard 0.100" (2.54 mm) pitch connectors, allowing 98 circuits in approximately the same PCB length as a 49-position 0.100" connector. This enables a 2× increase in signal routing density, which is critical for FPGA expansion boards, high-speed data acquisition modules, and mezzanine interfaces requiring more than 64 signals in a compact interconnect footprint.
For a defense electronics mezzanine application, what mating connector family is compatible with the SFM-149-T2-SM-D-A-K?
The SFM-149-T2-SM-D-A-K is designed to mate with SAMTEC's corresponding TSM or SHF series 0.050" pitch header strips in a 98-position dual-row configuration. The gold-plated contact system achieves contact resistance below 20 milliohms and supports insertion forces well within acceptable limits for field-replaceable modules used in defense electronics, where connector durability across 100+ mating cycles is a standard reliability requirement.
What reflow soldering specifications apply to the SFM-149-T2-SM-D-A-K during PCB assembly?
The SFM-149-T2-SM-D-A-K is designed for surface mount reflow soldering with a peak temperature tolerance of up to 260°C, compatible with standard lead-free solder profiles (SAC305 alloy). Its 0.050" (1.27 mm) pitch SMT pads require a precision stencil with approximately 0.5 mm apertures and a stencil thickness of 0.12–0.15 mm to achieve proper solder paste volume for reliable joint formation on all 98 positions during automated assembly.
