What are the key features of SFM-136-T2-SM-D-A-P-TR?
- 72 dual-row positions at 1.27 mm (0.050 inch) pitch delivering 144 total contacts for very-high-density mezzanine assemblies
- Solderable peg (SM) and polarization feature (P) ensuring precise, secure mechanical registration on the PCB
- High-reliability T2 contacts rated at 1.5 A each, suitable for aerospace, defense, and industrial environments
What is SFM-136-T2-SM-D-A-P-TR used for?
SFM-136-T2-SM-D-A-P-TR is designed for very-high-count board-to-board mezzanine stacking in high-reliability applications such as FPGA carrier boards, space-grade electronics, and military embedded computing. Its 144 contacts at 1.27 mm pitch enable simultaneous routing of high-speed digital buses, power rails, and analog signals across a single compact connector footprint. The solderable peg provides additional mechanical retention critical in vibration-intensive deployment environments.

Frequently Asked Questions
How many total contacts does SFM-136-T2-SM-D-A-P-TR provide, and what per-contact current can each carry?
SFM-136-T2-SM-D-A-P-TR has 72 positions in a dual-row configuration at 1.27 mm (0.050 inch) pitch, providing 144 total contact positions rated at 1.5 A each. This combination allows routing of both multiple power domains and high-speed digital buses across a single connector occupying approximately 92 mm of row length.
What mechanical advantage does the solderable peg (SM) add to SFM-136-T2-SM-D-A-P-TR in vibration-intensive environments?
The SM suffix indicates a solderable polarization peg that anchors the connector body to the PCB pad in addition to the 144 signal contact tails. In vibration-intensive environments such as airborne equipment and industrial machinery exceeding 10 g vibration loads, the peg distributes mechanical stress away from individual signal contacts, reducing the risk of solder joint fatigue at 1.27 mm pitch.
When is SFM-136-T2-SM-D-A-P-TR a better choice than two separate 36-position SFM connectors for the same signal count?
Using one SFM-136-T2-SM-D-A-P-TR instead of multiple smaller connectors reduces PCB keep-out area and eliminates alignment variability between separate connector centerlines. For signal counts reaching 144 pins, a single 72-position dual-row connector at 1.27 mm pitch maintains a continuous polarization reference, simplifying board layout and reducing assembly steps compared to placing four 36-contact parts individually.
