Frequently Asked Questions
What are the pin count and pitch specifications of the SFM-149-02-H-D-A connector?
The SFM-149-02-H-D-A has 98 total positions arranged in a dual-row format with 49 positions per row, operating on a 0.050 inch (1.27 mm) pitch. Gold-plated contacts ensure stable electrical performance with contact resistance maintained across a minimum of 500 mating cycles under standard operating conditions.
In which high-density interconnect designs does the SFM-149-02-H-D-A provide the most value?
FPGA mezzanine cards, processor daughter boards, and multi-channel data acquisition modules requiring more than 80 signal lines benefit most from this 98-position SMT socket. The dual-row 0.050 inch pitch layout accommodates high pin-count interfaces within a footprint smaller than 0.080 inch pitch alternatives, freeing additional PCB area for other components.
How does the SFM-149-02-H-D-A differ from the SFM-149-02-H-D-A-K variant?
The SFM-149-02-H-D-A is a standard surface mount socket without the polarization key feature, while the K-suffix variant adds a mechanical key to prevent incorrect mating orientation. Both share the same 98-position dual-row, 0.050 inch pitch design and gold-plated contacts, making them electrically identical but differing in assembly error-prevention capability.
