What are the key features of SFM-136-02-ZZ-D-A-K-TR?
- 72 pins in a dual-row 1.27 mm pitch SMT socket strip providing high density interconnect in a compact 23 mm strip length
- High-reliability socket contacts rated for repeated mating cycles, suitable for removable module and test fixture applications
- Tape-and-reel (TR) packaging compatible with automated pick-and-place machines for high-volume SMT production
What is SFM-136-02-ZZ-D-A-K-TR used for?
The SFM-136-02-ZZ-D-A-K-TR is used in board-to-board stacking applications such as processor daughter cards, wireless communication modules, and expansion boards where 72 signals must be routed between PCBs with minimal footprint. Its 1.27 mm pitch allows a strip length of approximately 23 mm for 36 pins per row, making it well suited for compact stackable designs in embedded computing, industrial controllers, and network appliances. The surface-mount construction enables reflow soldering alongside other SMT components, reducing assembly complexity.

Frequently Asked Questions
How many positions does the SFM-136-02-ZZ-D-A-K-TR provide, and at what pin pitch?
The SFM-136-02-ZZ-D-A-K-TR provides 72 positions in a dual-row layout with 1.27 mm (0.050 inch) pitch. With 36 pins per row, it can simultaneously route 24 data lines plus control, address, and power signals, making it suitable for parallel-bus daughter card connections in microcontroller and DSP development platforms.
How does the SFM-136-02-ZZ-D-A-K-TR compare to SFM-149-T2-ZZ-D-A-K-TR in terms of pin count and board space?
The SFM-136-02-ZZ-D-A-K-TR has 72 positions while the SFM-149 has 98 positions, both at 1.27 mm pitch. The 136-series strip spans approximately 23 mm versus approximately 31 mm for the 149-series, so designs that need fewer than 72 pins gain roughly 8 mm of PCB space per connector without switching pitch or series, easing routing in constrained layouts.
Is SFM-136-02-ZZ-D-A-K-TR compatible with standard reflow soldering and pick-and-place assembly?
Yes, the SFM-136-02-ZZ-D-A-K-TR is designed for lead-free SMT reflow soldering with peak oven temperatures up to 260°C per J-STD-020. The TR suffix confirms tape-and-reel packaging on 8 mm carrier tape, allowing automated pick-and-place placement of this 72-pin socket onto solder paste without manual handling, which reduces placement errors in high-volume production runs.
What header series mates with SFM-136-02-ZZ-D-A-K-TR for a complete board-to-board stack?
The SFM series mates with Samtec TSM, SHF, or FTE dual-row header connectors at 1.27 mm pitch with 36 pins per row (72 total). The final mated stack height depends on the header's post length above the board surface — standard options range from 3.5 mm to 11 mm — enabling designers to select the stack height that fits within the mechanical envelope of their enclosure or module housing.
