What are the key features of SFM-150-T2-STL-D-A-P?

  • 100-position dual-row layout on a 0.050" (1.27 mm) pitch providing a very high contact density for multi-channel signal and power routing between stacked PCBs
  • Solderable tail lock (STL suffix) feature mechanically anchors the connector body to the PCB during reflow soldering, preventing float or tilt that could cause open solder joints on the 100 contacts
  • High-reliability SFM-series contact design with gold-plated mating surfaces supporting extended mating cycle life exceeding 200 cycles and low contact resistance for sensitive signal lines

What is SFM-150-T2-STL-D-A-P used for?

The SFM-150-T2-STL-D-A-P is used in high-density FPGA mezzanine cards, embedded computing carrier boards, and multi-processor communication modules where 100 signal and power connections must pass between two PCBs through a compact 0.050-inch pitch SMT socket. Its tail lock feature and high-reliability contact system also make it well suited for aerospace data acquisition modules, industrial automation controllers, and medical imaging boards where joint integrity and signal continuity across thermal cycling are essential.

Frequently Asked Questions

What does the STL suffix mean on the SFM-150-T2-STL-D-A-P, and why is it important for reflow assembly?

The STL suffix indicates a solderable tail lock, which is an additional mechanical anchor that solders to the PCB alongside the 100 signal contacts. During reflow soldering, the tail lock prevents the connector body from floating or tilting on the molten solder, ensuring all 100 contacts on the 0.050-inch pitch land correctly and form reliable solder joints without manual fixturing.

How many positions and rows does the SFM-150-T2-STL-D-A-P provide, and what board-to-board pitch does it support?

The SFM-150-T2-STL-D-A-P is a 100-position dual-row socket strip, arranged as 2 rows of 50 contacts each, on a 0.050-inch (1.27 mm) pitch. This configuration routes 100 independent signal or power lines in a footprint approximately 2.5 inches long, making it one of the higher-density options in SAMTEC's SFM high-reliability socket strip family.

For a high-speed FPGA mezzanine design, how does the SFM-150-T2-STL-D-A-P's contact reliability compare to standard 0.100-inch pitch sockets?

The SFM-150-T2-STL-D-A-P uses high-reliability SFM-series contacts with gold-plated mating surfaces rated for over 200 mating cycles and contact resistance well below 20 milliohms. Compared to standard 0.100-inch pitch sockets, the 0.050-inch pitch halves the footprint for the same 100 connections, and the gold contacts support high-frequency signal integrity better than tin-plated alternatives at data rates common in FPGA interconnects.

What current rating per contact should designers use when routing mixed signal and power lines through the SFM-150-T2-STL-D-A-P?

SAMTEC SFM-series 0.050-inch pitch contacts are typically rated for 1 A per contact. For the 100-position SFM-150-T2-STL-D-A-P, individual contacts carrying 3.3 V or 5 V power rails can each supply up to 1 A, while signal contacts can share the same connector for LVDS, LVCMOS, and low-speed control lines without derating, provided total thermal dissipation across the connector stays within the rated limits.
