What are the key features of SFM-123-T2-F-D-A-P-TR?
- 46-position dual-row surface mount socket with 1.27 mm (0.050 inch) pitch provides high pin-density fine-pitch board-to-board interconnection
- T2 high-reliability contact rating and gold-plated (A) finish ensure low contact resistance and reliable mating over hundreds of insertion cycles
- Tape-and-reel (TR) and pick-and-place (P) compatible packaging support automated SMT assembly for high-volume production
What is SFM-123-T2-F-D-A-P-TR used for?
SFM-123-T2-F-D-A-P-TR serves as a mezzanine socket in aerospace avionics, defense electronics, and high-reliability industrial modules requiring 46-position fine-pitch 1.27 mm board-to-board connections. The gold-plated contacts and T2 reliability rating ensure consistent electrical performance in humid, vibrating, or thermally cycled environments found in ruggedized embedded systems. Tape-and-reel packaging and pick-and-place compatibility make it suitable for high-volume automated SMT assembly lines.

Frequently Asked Questions
What is the contact pitch and position count of SFM-123-T2-F-D-A-P-TR for fine-pitch mezzanine applications?
SFM-123-T2-F-D-A-P-TR has a 1.27 mm (0.050 inch) pitch with 46 total positions in a dual-row arrangement, providing 23 contacts per row. This fine pitch enables high-density board-to-board connections in compact mezzanine stacks where a 2.54 mm pitch connector would require twice the footprint area for the same pin count, benefiting space-constrained aerospace and defense PCB designs.
How does the gold-plated (A) contact finish of SFM-123-T2-F-D-A-P-TR benefit long-term connector reliability?
The gold-plated (A) contact finish on SFM-123-T2-F-D-A-P-TR provides excellent corrosion resistance and maintains contact resistance below 20 milliohms even after hundreds of mating cycles in humid or thermally cycled environments. Gold finish is preferred over tin in high-reliability aerospace and defense interconnect applications where connector failure could cause critical system faults and where typical tin-plated contacts might form oxide layers that increase contact resistance over time.
When should a designer choose SFM-123-T2-F-D-A-P-TR over a 2.54 mm pitch socket strip for a new board design?
A designer should choose SFM-123-T2-F-D-A-P-TR over a 2.54 mm pitch socket when the PCB layout budget is under 30 mm width for a 46-pin dual-row connector, since the 1.27 mm pitch occupies roughly half the board space of an equivalent 2.54 mm design. The T2 high-reliability rating and gold contacts are additionally justified when the application requires over 200 mating cycles, temperatures exceeding 85°C, or exposure to condensation and vibration typical of ruggedized military or industrial hardware.
