Key Features
- 94-position dual-row socket strip on a compact 0.050" (1.27mm) pitch achieves high signal density for mezzanine and board-to-board stacking in space-constrained designs
- High-reliability construction with gold-plated contacts ensures consistent electrical performance over thousands of mating cycles in vibration-prone industrial and military environments
- Surface mount termination enables single-process reflow assembly without through-hole drilling, reducing PCB manufacturing cost and maintaining a clean solder side
Applications
The SFM-147-02-FM-D-A is designed for high-density mezzanine card and daughterboard interconnect applications in military electronics, aerospace avionics, and high-performance computing where 0.050" pitch and 94-pin capacity are required on a surface mount footprint. Its gold-plated contacts and high-reliability construction make it suitable for test and measurement equipment that demands stable electrical contact over repeated insertions. Industrial robotics and medical instrumentation systems also use this socket strip to connect daughterboards carrying signal processing or sensor interface circuitry.

Frequently Asked Questions
How many contact positions does the SFM-147-02-FM-D-A provide, and what pitch separates adjacent pins?
The SFM-147-02-FM-D-A provides 94 positions arranged in a dual-row configuration at 0.050" (1.27mm) pitch. This fine pitch allows 47 contacts per row in a compact footprint, enabling high pin-count board-to-board connections in space-limited mezzanine card and module designs.
What current rating does each contact carry in the SFM-147-02-FM-D-A, and how does this support mixed signal and power routing?
Each contact in the SFM-147-02-FM-D-A is rated at 1A, which is standard for 0.050" pitch socket connectors. Designers can bundle 5 or 10 contacts in parallel for a 5A or 10A power rail while routing signal lines on the remaining pins, giving full flexibility for mixed power-and-signal mezzanine card designs.
Why would an engineer choose SFM-147-02-FM-D-A over a 0.100" pitch socket strip for a high-density daughterboard design?
At 0.050" (1.27mm) pitch, the SFM-147-02-FM-D-A requires approximately half the linear board space of a 0.100" pitch alternative to achieve the same 94-pin count. This allows engineers to fit more signals across a narrower board edge, leaving room for components on both PCBs in a stacked mezzanine assembly with a standoff height as low as 5mm.
How does the surface mount design of SFM-147-02-FM-D-A simplify PCB manufacturing compared to through-hole socket strips?
As a surface mount component, the SFM-147-02-FM-D-A is placed and soldered during the standard SMT reflow pass, eliminating the separate wave-solder or hand-soldering step required for through-hole connectors. This reduces manufacturing lead time and is particularly valuable in automated high-volume assembly lines producing military or aerospace boards where process control is critical.
