What are the key features of SFM-149-02-L-D-A-K-TR?
- 98-position dual-row socket at 0.050" (1.27 mm) pitch delivers twice the density of standard 0.100" connectors in the same board area
- High-reliability contact design rated for repeated mating cycles, ideal for field-replaceable mezzanine modules
- Tape-and-reel (-TR) packaging with keying (-K) and alignment features (-A) ensures error-free automated placement and correct mating orientation
What is SFM-149-02-L-D-A-K-TR used for?
The SFM-149-02-L-D-A-K-TR is designed for ultra-high-density mezzanine and daughter-card interconnects in space-constrained embedded computing, communications, and defense electronics. Its 0.050" pitch accommodates 98 signals in a footprint roughly half the size of equivalent 0.100" connectors, enabling compact multi-board stacking in rugged or portable systems. The keying and alignment features (-A -K) prevent mis-mating, making it suitable for field-serviceable modules and test fixtures.

Frequently Asked Questions
What pitch and position count does the SFM-149-02-L-D-A-K-TR offer, and how does it compare to 0.100" alternatives?
The SFM-149-02-L-D-A-K-TR uses a 0.050" (1.27 mm) pitch with 98 total positions across 2 rows of 49. This half-pitch layout achieves the same signal count as a 0.100" dual-row connector in roughly 50% of the PCB footprint, making it ideal for space-constrained designs where board real estate is at a premium.
Which embedded or defense applications are best served by the high-reliability design of this SAMTEC socket strip?
Rugged embedded computing modules, software-defined radio platforms, and aerospace payload boards that require field-replaceable daughter cards are ideal candidates. The high-reliability contact system supports hundreds of mating cycles, and the 98-position count accommodates wide data buses or mixed signal-power rails in a single 0.050" pitch connector.
What do the -A and -K suffixes in SFM-149-02-L-D-A-K-TR indicate for procurement and assembly planning?
The -A suffix denotes an alignment post that mechanically locates the connector on the PCB during reflow soldering, reducing placement error to under 0.1 mm. The -K suffix indicates a polarization key that physically prevents incorrect mating orientation, which is critical for 98-position connectors where reversing insertion would damage up to 98 signal lines simultaneously.
