What are the key features of SFM-144-02-LM-D-K-TR?
- 88-pin dual-row configuration on 1.27 mm (0.050 inch) pitch for high-density board-to-board surface mount connections
- Polarization keying post (K suffix) prevents misoriented mating and protects all 88 contacts during field installation
- Tape-and-reel (TR) packaging enables seamless integration with automated SMT pick-and-place production lines
What is SFM-144-02-LM-D-K-TR used for?
The SFM-144-02-LM-D-K-TR is designed for high-density board-to-board applications such as processor module sockets, FPGA mezzanine interfaces, and memory expansion boards requiring 88 contacts at 1.27 mm pitch. Its surface mount termination and tape-and-reel packaging support high-volume automated assembly on commercial and industrial PCBs. The keyed design prevents damage from misaligned mating, making it especially valuable in field-replaceable module systems and test-and-measurement backplanes.

Frequently Asked Questions
How many pins does SFM-144-02-LM-D-K-TR provide and what contact pitch does it use?
The SFM-144-02-LM-D-K-TR has 88 pins arranged in a dual-row surface mount configuration on a 1.27 mm (0.050 inch) pitch. This combination of pin count and pitch makes it suitable for wide parallel bus interfaces and high-channel-count signal routing between adjacent PCBs in a stacked board assembly.
What role does the keying post (K suffix) play in SFM-144-02-LM-D-K-TR multi-board assemblies?
The keying post in SFM-144-02-LM-D-K-TR prevents incorrect orientation during mating, protecting all 88 pins from damage caused by misaligned insertion in multi-board assemblies. This is critical in field-replaceable module systems where the 1.27 mm pitch layout must align precisely and carry up to 1.5 A per contact without mechanical or electrical damage.
What advantages does tape-and-reel (TR) packaging provide for SFM-144-02-LM-D-K-TR in high-volume SMT production?
Tape-and-reel packaging for SFM-144-02-LM-D-K-TR enables automated pick-and-place machines to place the 88-pin dual-row connector directly onto PCB pads with consistent repeatability, eliminating manual handling and orientation errors. This is especially beneficial in embedded computing and consumer electronics manufacturing where production volumes and solder joint quality across all 88 pins directly impact per-unit assembly cost.
