What are the key features of SFM-123-02-L-D-A-P-TR?
- 46-position dual-row socket on 0.050 inch (1.27 mm) pitch provides 92 contacts in a compact footprint suited for FPGA and processor mezzanine interfaces
- Polarized housing (P) prevents incorrect connector mating orientation, eliminating assembly errors and protecting sensitive signal lines during board insertion
- Tape-and-reel (TR) packaging with 2 mm tail (02) ensures precise SMT placement compatibility for automated high-volume production assembly
What is SFM-123-02-L-D-A-P-TR used for?
The SFM-123-02-L-D-A-P-TR is used in compact embedded computing modules, FPGA expansion cards, and instrumentation daughter boards where a medium-density mezzanine connection is required with orientation protection. Its 0.050-inch pitch dual-row layout supports up to 46 differential pairs or a mix of power and single-ended signals in a footprint approximately 60 mm long. The polarized design and tape-and-reel packaging make it an efficient choice for production environments requiring error-free automated assembly.

Frequently Asked Questions
What is the total contact count and pitch of the SFM-123-02-L-D-A-P-TR, and how does polarization protect the circuit?
The SFM-123-02-L-D-A-P-TR provides 92 total contacts across 46 dual-row positions on a 0.050 inch (1.27 mm) pitch, and the polarized housing (P) includes a mechanical key that prevents reverse mating, protecting differential pair assignments and power pins from 180-degree misconnection that could damage FPGA I/O banks or burn out power supply traces.
How does the 2 mm tail length (02) of the SFM-123-02-L-D-A-P-TR affect solder joint quality during SMT reflow?
The 2 mm tail length provides a balanced solder fillet height that accommodates board-level warpage during reflow and ensures that all 92 SMT contacts maintain contact with the PCB pad throughout the 260°C peak temperature solder profile, achieving joint strength consistent with IPC-A-610 Class 2 or Class 3 requirements.
In a dual-module FPGA design, how many differential pairs can the SFM-123-02-L-D-A-P-TR route between stacked boards?
The SFM-123-02-L-D-A-P-TR provides 92 contacts, which when allocated as differential pairs with ground shielding, can accommodate up to 46 differential pairs in a single connector body, supporting high-speed interfaces such as 46-lane LVDS buses, 23-channel SERDES operating at rates up to 10 Gbps per pair, or mixed signal and power arrangements across a 0.050 inch pitch dual-row footprint.
What is the operating temperature range of the SFM-123-02-L-D-A-P-TR, and can it be used in extended industrial environments?
SAMTEC SFM series connectors are rated for an operating temperature range of -55°C to +125°C, covering both standard commercial and extended industrial temperature profiles, making the SFM-123-02-L-D-A-P-TR suitable for outdoor industrial control equipment, railway electronics, and military-grade embedded modules that must operate reliably across a 180°C temperature span.
