What are the key features of SFM-138-T2-ZZ-D-A-K-TR?
- 76-position dual-row 1.27 mm pitch layout provides 76 independent 1 A contacts in a 24.6 mm x 2.54 mm SMT footprint for high-density mezzanine interconnects
- Gold-plated contact finish rated for 200+ mating cycles ensures consistent sub-20 mΩ contact resistance across the full 76-pin interface
- Tape-and-reel packaging and SMT termination enable automated pick-and-place assembly with standard 260°C peak reflow profiles
What is SFM-138-T2-ZZ-D-A-K-TR used for?
The SFM-138-T2-ZZ-D-A-K-TR is used in FPGA mezzanine cards, high-speed data acquisition boards, and multi-processor embedded platforms that require 76 or more signal lanes between stacked PCBs at 1.27 mm pitch. Its high-reliability gold contacts maintain electrical continuity across repeated board-swap cycles in test and measurement systems where daughterboards are frequently exchanged. The compact dual-row format keeps the connector within a narrow board-edge zone, maximizing usable PCB area on the host module.

Frequently Asked Questions
How many signal lines does SFM-138-T2-ZZ-D-A-K-TR provide and what is the maximum current per contact?
SFM-138-T2-ZZ-D-A-K-TR provides 76 individual signal contacts arranged in 2 rows at 1.27 mm pitch, each rated for 1 A continuous current at up to 100 V; the cumulative connector capacity is 76 A when all pins carry current, which is sufficient for mixed signal and distributed power delivery on large FPGA boards.
For a 76-signal FPGA mezzanine card design, how does SFM-138-T2-ZZ-D-A-K-TR compare to a 2.54 mm pitch alternative?
At 1.27 mm pitch, SFM-138-T2-ZZ-D-A-K-TR spans approximately 24.6 mm along the board edge compared to roughly 48 mm for an equivalent 2.54 mm pitch 76-pin strip; this 50% reduction in connector length frees board area for decoupling capacitors or routing channels alongside the FMC site on constrained PCBs.
What mating header is designed to pair with SFM-138-T2-ZZ-D-A-K-TR in a stacked PCB assembly?
SAMTEC TSM-138 series headers in the matching 1.27 mm pitch dual-row format are the intended mating partners; the TSM-138 plus SFM-138 assembly delivers a 76-position 1.27 mm stacked interface with a defined mated height of 4.57 mm and a per-contact rating of 1 A at 100 V, fully compatible with standard pick-and-place SMT assembly.
