Frequently Asked Questions
How many contacts does the SFM-138-02-L-D-A-K provide and in what arrangement?
The SFM-138-02-L-D-A-K provides 76 contacts arranged in a dual-row, surface-mount configuration at a 0.050" (1.27 mm) pitch. This layout is typical in FPGA and processor module stacking where maximizing signal count within a constrained board area is essential.
In which environments is the SFM-138-02-L-D-A-K's high-reliability rating most beneficial?
Its high-reliability rating is most valuable in industrial automation, defense electronics, and embedded computing applications subject to vibration, thermal cycling between -55°C and +125°C, and repeated mating cycles. The gold-plated contacts maintain low contact resistance even after hundreds of insertion and extraction events.
Can the SFM-138-02-L-D-A-K replace a through-hole connector in an existing board redesign?
Replacing a through-hole connector with the SFM-138-02-L-D-A-K requires a PCB land-pattern update to accommodate its SMT pads at 0.050" (1.27 mm) pitch, but the 76-pin dual-row format offers a lower board height and enables automated reflow assembly, reducing overall production cost in moderate-to-high volume runs.
