What are the key features of SFM-120-02-F-D-A-P-TR?
- 40-position dual-row layout at 1.27 mm (0.050") pitch providing 40 signal contacts in a compact SMT connector body
- Through-hole assist posts (A option) anchoring the connector to the PCB for improved mechanical stability during mating and vibration
- Polarization peg (P option) preventing reverse insertion of the 40-pin dual-row connector to avoid wiring damage
- Flat lead (F) contact style with tape-and-reel (TR) packaging enabling fully automated high-volume SMT assembly
What is SFM-120-02-F-D-A-P-TR used for?
The SFM-120-02-F-D-A-P-TR is suited for high-density mezzanine and daughter-card interfaces in embedded computing, FPGA carrier boards, and telecommunications infrastructure where 40-pin dual-row board-to-board connections at 1.27 mm pitch are needed. The combination of through-hole assist posts and polarization peg ensures reliable assembly and mechanical retention in industrial or aerospace equipment subject to shock and vibration. Tape-and-reel packaging supports automated pick-and-place manufacturing at production volumes requiring consistent 1.27 mm pitch placement accuracy.

Frequently Asked Questions
What is the position count and pitch of the SFM-120-02-F-D-A-P-TR, and how does it support high-density routing?
The SFM-120-02-F-D-A-P-TR has 40 positions in a dual-row configuration with 1.27 mm (0.050 inch) pitch, providing 20 contacts per row. This high-density 1.27 mm pitch packs 40 signal lines into a board footprint of approximately 25.4 mm in length, making it ideal for FPGA expansion buses, DDR memory interfaces, and other wide parallel buses on compact mezzanine boards.
How do the through-hole assist posts (A option) on the SFM-120-02-F-D-A-P-TR improve connector reliability in high-vibration environments?
The through-hole assist posts anchor the SMT connector body into PCB drill holes, distributing mating forces across the board rather than relying solely on solder pads. In vibration-intensive applications such as industrial machinery or aerospace electronics rated for 5 G to 20 G sustained vibration, the assist posts prevent solder joint fatigue on the 40-pin dual-row 1.27 mm pitch connector, extending mean time between failure significantly compared to SMT-only mounting.
For a compact FPGA carrier board with limited PCB area, how does the SFM-120-02-F-D-A-P-TR compare to a 2.54 mm pitch 40-pin connector?
At 1.27 mm pitch, the SFM-120-02-F-D-A-P-TR requires a board footprint roughly half the length of a 2.54 mm pitch 40-pin dual-row connector, saving approximately 25 mm of PCB length. For FPGA carrier boards where the expansion connector zone is constrained to a 30 mm × 10 mm area, the 1.27 mm pitch 40-position connector fits comfortably while the 2.54 mm pitch alternative would overflow the available space.
What role does the polarization peg (P option) play in preventing assembly errors with the SFM-120-02-F-D-A-P-TR?
The polarization peg is a physical asymmetric feature that mates only with a corresponding keyway on the mating header, ensuring the 40-pin dual-row connector can only be installed in the correct orientation. Without this peg, a 40-position connector at 1.27 mm pitch could be inserted 180 degrees reversed, applying voltages to wrong pins and potentially damaging ICs on boards running at 3.3V or 5V logic levels.
