What are the key features of SFM-119-L2-L-D-A-P-TR?
- 38-position dual-row socket strip with 0.050" (1.27 mm) pitch enabling high-density mezzanine and board-to-board signal routing
- Long post (L) option accommodates larger board-to-board stack heights or provides pass-through connectivity to a third board
- Polarization (P) keying prevents incorrect connector mating orientation, improving assembly reliability in production
- Tape-and-reel (TR) packaging supports automated pick-and-place SMT assembly for high-volume PCB production runs
What is SFM-119-L2-L-D-A-P-TR used for?
The SFM-119-L2-L-D-A-P-TR is used in multi-board stacking and mezzanine interconnect designs where 38 signal positions at 0.050" pitch are needed with extended stack height capability. Its long post option makes it suitable for three-board sandwich configurations in embedded computing and modular RF designs. The tape-and-reel format supports automated SMT production in high-volume runs of thousands of units for industrial, telecommunications, and defense electronics.

Frequently Asked Questions
What does the long post (L) designation mean for board stacking with the SFM-119-L2-L-D-A-P-TR?
The long post (L) designation means the connector posts extend further than the standard length, enabling a greater board-to-board stack height typically exceeding 8 mm, which accommodates taller components on the intermediate board or allows a third board to be stacked using a pass-through pin configuration in multi-tier embedded module designs.
How many signal positions per row does the SFM-119-L2-L-D-A-P-TR provide at 0.050" pitch?
The SFM-119-L2-L-D-A-P-TR has 38 total positions in a dual-row arrangement with 19 contacts per row and a 0.050" (1.27 mm) center-to-center pitch, providing a high-density signal interface suitable for FPGA module connections, RF front-end boards, and data acquisition mezzanine cards.
Why is polarization (P) important on a 38-position dual-row connector like the SFM-119-L2-L-D-A-P-TR?
On a 38-position, 0.050" pitch dual-row connector, incorrect mating can short power to signal pins across 38 contact pairs, potentially damaging the connected PCB or components; the polarization (P) feature adds a mechanical key that physically prevents reverse insertion, reducing costly repair of boards running at 3.3 V or 5 V logic levels.
Is the SFM-119-L2-L-D-A-P-TR available in a format suitable for automated high-volume PCB assembly lines?
Yes, the TR suffix designates tape-and-reel packaging, which feeds directly into standard pick-and-place equipment for automated SMT placement; the tape pitch and cavity dimensions comply with EIA-481 standards, allowing smooth integration into reflow solder assembly lines processing thousands of boards per shift.
