What are the key features of SFM-103-L2-LM-D-A-P?
- 6-position dual-row socket on 1.27 mm (0.050 inch) pitch for compact high-density PCB mezzanine interconnects
- Alignment post (A-P) feature ensures precise 1.27 mm pitch mating connector registration, preventing misalignment during assembly
- High-reliability gold-plated contacts with LM (longer mating length) variant rated for extended insertion cycles in demanding applications
What is SFM-103-L2-LM-D-A-P used for?
The SFM-103-L2-LM-D-A-P is designed for compact mezzanine and daughter card stacking applications in portable instruments, medical devices, and embedded system modules where a low 6-position footprint is needed. The LM (longer mating length) contact option increases mechanical engagement length, improving robustness in vibration-prone or field-removable daughter board applications. Alignment posts enable repeatable blind-mate assembly without visual alignment, speeding up module integration in box-build environments.

Frequently Asked Questions
What does the LM suffix indicate in the SFM-103-L2-LM-D-A-P part number and why does it matter?
The LM suffix denotes longer mating length contacts compared to standard SFM variants. Longer mating engagement typically increases the contact overlap by several tenths of a millimeter on the 1.27 mm pitch socket, improving mechanical retention and maintaining stable low-resistance connections in environments with vibration or repeated module swaps, such as industrial field instruments or removable compute modules.
For what PCB application would a 6-position 1.27 mm pitch dual-row socket like SFM-103-L2-LM-D-A-P be selected over a larger connector?
A 6-position dual-row socket at 1.27 mm pitch is ideal for compact sub-modules such as sensor breakout boards, clock distribution daughter cards, or small power conditioning mezzanines where only 6 signal or power pins are required. The small 1.27 mm pitch body occupies minimal PCB area compared to 2.54 mm pitch alternatives carrying the same 6-pin count, making it the preferred choice in size-constrained portable or wearable device designs.
How does the alignment post (A-P) option on the SFM-103-L2-LM-D-A-P simplify PCB assembly?
The A-P alignment post inserts through a dedicated PCB hole and locks the socket into precise position before reflow soldering, preventing lateral shift across the 1.27 mm pitch pads during the thermal cycle. This mechanical pre-registration is especially valuable in automated SMT lines processing boards with multiple fine-pitch connectors, ensuring every 6-position socket lands accurately on its copper pads without manual touch-up.
