What are the key features of SFM-123-02-H-D-LC?
- 46-position dual-row layout at 0.050 inch (1.27 mm) pitch for high-density SMT board-to-board mating
- High-reliability socket construction with low contact resistance ensuring consistent signal integrity over thousands of mating cycles
- Surface-mount termination compatible with standard reflow soldering processes for automated PCB assembly
- Latching contact design (LC variant) providing positive retention force to resist accidental unmating in vibration-prone environments
What is SFM-123-02-H-D-LC used for?
SFM-123-02-H-D-LC is widely used in high-density PCB stacking applications such as FPGA mezzanine cards, memory expansion modules, and industrial compute modules requiring reliable 46-position dual-row connectivity at 1.27 mm pitch. Its surface-mount profile suits backplane interconnects and test-fixture board designs where low-profile connectors and automated assembly are critical. The latching variant is particularly valued in aerospace, military, and ruggedized industrial electronics where vibration resistance is a priority.

Frequently Asked Questions
What is the pin pitch and total contact count of SFM-123-02-H-D-LC, and how does it compare to standard 0.100-inch connectors?
SFM-123-02-H-D-LC features a 0.050 inch (1.27 mm) pitch with 46 positions arranged in a dual-row configuration, offering roughly half the board footprint of traditional 0.100-inch pitch connectors while maintaining the same number of signals in a more compact surface-mount package.
In which high-reliability application environments is SFM-123-02-H-D-LC typically deployed?
This connector is used in aerospace avionics, military rugged electronics, and industrial control boards where its latching contact mechanism provides secure retention across vibration levels up to 20 G and temperature ranges from -55°C to +125°C, ensuring connection integrity under harsh conditions.
Is SFM-123-02-H-D-LC compatible with automated SMT reflow assembly and what solder profile is recommended?
Yes, SFM-123-02-H-D-LC is surface-mount compatible and rated for standard lead-free reflow profiles peaking at 260°C, making it suitable for automated pick-and-place assembly with 0402 and 0603 component coplanarity tolerances on 1.27 mm pitch pads.
What mating connector in the SAMTEC SFM series pairs with SFM-123-02-H-D-LC for dual-row board-to-board stacking?
SFM-123-02-H-D-LC mates with SAMTEC TSM and SSM series 0.050-inch pitch dual-row headers, where the 46-position dual-row socket accepts a matching 46-pin (23 per row) 1.27 mm pitch header pin to complete the board-to-board interconnect with full 46-circuit continuity.
