What are the key features of SFM-102-02-H-D-A-P?
- 4-position dual-row socket at 0.050 inch (1.27 mm) pitch provides a compact, high-density interface in the smallest possible footprint for minimalist power or control signal connections
- High-reliability contact design supports extended mating cycles and stringent contact force specifications, meeting requirements for aerospace, defense, and industrial embedded systems
- Surface-mount termination enables standard SMT reflow assembly, eliminating through-hole drilling and simplifying double-sided PCB manufacturing
- Dual-row layout places 2 contacts per row, allowing differential pair or power-plus-signal configurations within a single compact 4-pin connector body at 0.050 inch pitch
What is SFM-102-02-H-D-A-P used for?
The SFM-102-02-H-D-A-P is designed for compact board-to-board and mezzanine interconnects in high-reliability embedded systems, avionics modules, and small-form-factor compute cards where minimal pin count and tiny PCB footprint are required. Its 4-position dual-row socket at 0.050 inch pitch is commonly used for differential pair interfaces, power rails, or dedicated control signal connections on FMC mezzanine cards and VITA-compliant embedded computing modules. The high-reliability construction suits applications in military electronics, space-adjacent instrumentation, and industrial safety systems that demand verified connector performance over extended service life.

Frequently Asked Questions
How many positions does SFM-102-02-H-D-A-P provide and what pitch does it use?
The SFM-102-02-H-D-A-P provides 4 positions in a dual-row layout at 0.050 inch (1.27 mm) pitch, yielding 2 contacts per row in one of the most compact socket footprints available in the SAMTEC SFM series. This minimal pin count at 0.050 inch pitch is suited for space-constrained interfaces such as differential signal pairs, isolated power connections, or dedicated control lines on small embedded modules and mezzanine daughtercards.
Why choose SFM-102-02-H-D-A-P over a standard commercial socket for aerospace or defense designs?
The high-reliability (HR) designation indicates the SFM-102-02-H-D-A-P is built to tighter contact retention, normal force, and plating uniformity specifications than standard commercial connectors, supporting more mating cycles and reliable operation under vibration and thermal stress. For avionics line-replaceable modules and military embedded computing boards that must survive harsh environments and extended service intervals, the HR rating provides traceable manufacturing controls and higher confidence in contact integrity at 0.050 inch pitch over the product's operational life.
What soldering process is required for SFM-102-02-H-D-A-P and can it be used with lead-free solder?
The SFM-102-02-H-D-A-P uses surface-mount (SMT) termination pads that are compatible with standard lead-free reflow soldering at peak temperatures up to 260 °C per IPC J-STD-020, making it fully compliant with RoHS manufacturing requirements. The 4-position footprint at 0.050 inch pitch is small enough to be placed with standard nozzle diameters on automated pick-and-place machines, and the low contact count allows rapid visual or automated optical inspection after reflow.
How does the dual-row arrangement of SFM-102-02-H-D-A-P benefit a differential pair or power-signal interface?
With 2 contacts per row in a dual-row configuration at 0.050 inch pitch, the SFM-102-02-H-D-A-P naturally groups a differential pair (D+ and D-) in one row and a ground or power pair in the other, keeping critical signal pairs geometrically close to minimize skew and maintain matched impedance on high-speed interfaces. This layout also allows one row to carry a supply voltage (e.g., 3.3 V) while the adjacent row carries complementary signals, combining power delivery and control signaling in a single 4-pin 0.050 inch connector rather than two separate connectors.
