What are the key features of SFM-148-02-ZZ-D-A-K-TR?
- 96-position dual-row 1.27 mm pitch SMT socket delivers the highest-density single-body connector option for mezzanine and daughtercard stacking in a 31.6 mm edge footprint
- Gold-plated contacts rated 1 A per pin and 100 V support simultaneous signal and distributed power routing across all 96 positions
- -02 height variant provides a specific board-to-board mated standoff optimized for standard height FMC and module stacking configurations
What is SFM-148-02-ZZ-D-A-K-TR used for?
The SFM-148-02-ZZ-D-A-K-TR serves as the primary high-density stacking connector in FPGA development boards, software-defined radio platforms, and high-speed data acquisition systems requiring 96 parallel signal lanes between a host board and a mezzanine module. Its 1.27 mm pitch constrains the connector to a 31.6 mm edge footprint, preserving routing channels alongside the FMC site on resource-limited PCBs. High-volume deployments benefit from tape-and-reel packaging that supports fully automated SMT assembly at 260°C peak reflow temperatures.

Frequently Asked Questions
How does SFM-148-02-ZZ-D-A-K-TR achieve 96 positions while maintaining a compact PCB footprint at 1.27 mm pitch?
By using a dual-row layout at 1.27 mm (0.050") pitch, SFM-148-02-ZZ-D-A-K-TR fits 96 contacts within approximately 31.6 mm x 2.54 mm of PCB land area; this is roughly 40% shorter than a comparable 2.54 mm pitch connector, which would require about 60 mm along the board edge to house the same number of pins.
What current capacity does SFM-148-02-ZZ-D-A-K-TR offer across all 96 contacts, and how should power pins be allocated?
Each of the 96 contacts is individually rated for 1 A at 100 V, giving a theoretical total of 96 A if all pins carry current; in practice, designers allocate 10-20 pins for distributed power delivery at 3.3 V or 5 V and dedicate the remaining 76-86 pins to high-speed signal lines, staying within the 1 A per-pin derating for thermal safety.
Which SAMTEC male header series mates with SFM-148-02-ZZ-D-A-K-TR, and what is the assembled mated height?
SAMTEC TSM-148 series headers in the same 1.27 mm dual-row pitch are the designed mating partners for SFM-148-02-ZZ-D-A-K-TR; the -02 height suffix on the socket selects a specific board-to-board standoff compatible with standard FMC module heights, producing a fully mated assembly rated at 96 positions, 1 A per contact, and 100 V maximum voltage.
