Key Features
- 84 positions in a dual-row surface-mount configuration at 0.050 inch (1.27 mm) pitch for high-density interconnects
- High-reliability socket strip construction ensures consistent mating force and low contact resistance over thousands of insertion cycles
- Surface-mount termination style enables automated SMT assembly and eliminates through-hole drilling for faster PCB manufacturing
- Dual-row layout maximises signal density per unit PCB length, ideal for compact module-to-baseboard interfaces
Applications
The SFM-142-02-FM-D-A is ideal for high-density board-to-board and mezzanine connector applications in FPGA development boards, test-and-measurement equipment, and embedded computing modules that require 84 contacts in a minimal footprint. Its 0.050-inch pitch socket strip is commonly used in military-grade electronics, medical instrumentation, and industrial controllers where reliable mating cycles and surface-mount compatibility are essential. The dual-row design also suits daughter-card and piggyback module connections in telecommunications and data acquisition systems.

Frequently Asked Questions
How many contact positions does the SFM-142-02-FM-D-A provide, and how are they arranged?
The SFM-142-02-FM-D-A provides 84 contact positions arranged in 2 rows of 42 contacts each, at a 0.050-inch (1.27 mm) pitch. This dual-row surface-mount layout delivers a high signal density suitable for FPGA mezzanine cards, processor daughter boards, and test-equipment modules where maximising the number of I/O connections per millimetre of connector length is a design requirement.
What is the contact pitch of the SFM-142-02-FM-D-A, and how does it compare to standard 0.1-inch pitch connectors?
The SFM-142-02-FM-D-A uses a 0.050-inch (1.27 mm) contact pitch, which is half the spacing of standard 0.1-inch (2.54 mm) pitch connectors. This tighter pitch means the 84-position dual-row connector occupies roughly half the PCB footprint of an equivalent standard-pitch connector, enabling designers to fit more interconnects in board areas measuring less than 30 mm in length while maintaining reliable surface-mount solder joints.
What mounting style does the SFM-142-02-FM-D-A use, and how does this affect PCB assembly?
The SFM-142-02-FM-D-A uses surface-mount (SM) termination, so all 84 contacts are soldered directly to PCB pads during standard SMT reflow assembly without requiring through-hole drilling. This simplifies PCB manufacturing, reduces board thickness requirements, and allows the connector to be placed on the same automated pick-and-place line as other SMT components, cutting assembly time and cost for high-volume production runs with double-sided board layouts.
For which high-reliability application environments is the SAMTEC SFM-142-02-FM-D-A rated, and what design life does it support?
SAMTEC classifies the SFM-142-02-FM-D-A as a high-reliability socket strip, making it suited for mil/aero, medical, and industrial environments that demand consistent performance over extended operating life. The connector is designed to withstand repeated mating cycles typically rated in the hundreds to thousands of insertions, with low contact resistance maintained across the full 84-position dual-row interface under vibration and thermal cycling conditions encountered in rack-mounted or field-deployed equipment operating from -55°C to +125°C.
