Frequently Asked Questions
How many contacts does the S2M-120-01-L-D provide and what is the row arrangement?
The S2M-120-01-L-D provides 40 contacts arranged in a dual-row configuration at .100" (2.54 mm) pitch, with a body length of 1.589 inches. Each row contains 20 female sockets, making it compatible with standard 40-pin dual-row male header strips used across development boards, daughter cards, and embedded computing platforms.
In which embedded computing or prototyping boards does the S2M-120-01-L-D see the most use?
The S2M-120-01-L-D sees wide use in Arduino Mega-compatible shields and carrier boards, Raspberry Pi HAT connectors, and 40-pin bus connectors on single-board computers. Its .100" dual-row female socket format matches the industry-standard expansion headers found on microcontroller development kits, making it a go-to component for stackable module designs requiring 40 signal and power pins.
How does the through-hole mounting of S2M-120-01-L-D compare to surface mount socket strips for mechanical strength?
Through-hole mounting used on the S2M-120-01-L-D provides superior pull-out strength compared to surface mount alternatives because the pins are anchored through the PCB and soldered on the opposite side. This is advantageous in applications subject to repeated mating cycles, mechanical stress, or board handling, where surface mount sockets can delaminate under shear forces. Engineers typically specify through-hole sockets when mating cycles exceed 100 insertions.
Can the S2M-120-01-L-D be used as a drop-in replacement for other 40-pin dual-row .100" female headers?
Yes. The S2M-120-01-L-D follows the industry-standard .100" (2.54 mm) dual-row 40-position layout, meaning it is mechanically and electrically compatible with generic 40-pin dual-row female headers from most connector manufacturers. Designers should verify the pin length, insulator height, and contact current rating—typically 3 A per pin for this class—before substituting to confirm form and fit compatibility in their specific board stack.
