What are the key features of SFM-103-02-SM-D-K-TR?
- 6-position dual-row high-reliability SMT socket strip at 1.27 mm (0.050") pitch for compact 12-contact mezzanine and module interconnects
- Keying (K) feature prevents incorrect mating orientation, protecting sensitive circuits on 3.3 V or 5 V signal lines in field-replaceable assemblies
- Tape-and-reel (TR) packaging with gold-plated contacts enables automated SMT assembly at up to 260°C for high-reliability production environments
What is SFM-103-02-SM-D-K-TR used for?
SFM-103-02-SM-D-K-TR is suited for small-format mezzanine board interconnects, sensor module interfaces, and compact daughter card connections in aerospace, defense, and industrial electronics requiring 12 high-reliability contacts at 1.27 mm pitch. Its keyed dual-row configuration prevents mis-mating in compact module assemblies where 6-position per row connectors carry critical power or control signals in space-constrained PCB designs. The tape-and-reel format supports automated SMT production lines used in high-reliability manufacturing for military and avionics applications.

Frequently Asked Questions
How many total contact positions does SFM-103-02-SM-D-K-TR provide, and what is its pitch?
SFM-103-02-SM-D-K-TR provides 3 positions per row in a dual-row layout, yielding 6 total high-reliability socket positions at 1.27 mm (0.050") pitch. Despite its compact 6-position count, the gold-plated contacts deliver the same contact reliability as larger SFM series connectors, making it suitable for critical low-pin-count signal interfaces in aerospace and defense modules.
What does the K (keying) option add to SFM-103-02-SM-D-K-TR for field-replaceable module designs?
The K (keying) option on SFM-103-02-SM-D-K-TR introduces a mechanical polarization feature that ensures the 6-position dual-row connector can only mate in one correct orientation. In field-replaceable module (FRM) applications common in avionics, military computing, and industrial instrumentation, this prevents reversed insertion of 3.3 V or 5 V power and signal connections, reducing maintenance errors and protecting expensive electronics.
When would SFM-103-02-SM-D-K-TR be chosen over a larger SFM series connector for a sensor interface design?
SFM-103-02-SM-D-K-TR is specifically chosen when the sensor interface requires only 6 contacts at 1.27 mm pitch, minimizing PCB footprint to under 8 mm row length while maintaining high-reliability gold-plated contact performance. Its SM (standard mating height) profile keeps the above-board height minimal, enabling low-clearance stacking between a host board and a compact sensor module in embedded instrumentation designs.
Is SFM-103-02-SM-D-K-TR compatible with standard lead-free reflow soldering, and what temperature limits apply?
Yes, SFM-103-02-SM-D-K-TR is compatible with lead-free reflow soldering processes. The SMT contacts and housing material are qualified for peak reflow temperatures up to 260°C per IPC/JEDEC J-STD-020 classification, and the connector maintains full performance across its -55°C to +125°C operating temperature range, meeting the requirements of most high-reliability industrial and aerospace production processes.
