What are the key features of SFM-124-T2-H-D-A-P-TR?
- 48-position dual-row socket at 0.050 inch (1.27 mm) pitch providing 96 total mated contacts in a compact SMT footprint for high-density FPGA and SoC mezzanine interfaces
- High-profile (H) mating height increases board-to-board clearance to accommodate taller components in the inter-board space of stacked PCB assemblies
- High-reliability SFM contact system engineered for extended mating cycle life and stable impedance, suitable for aerospace, defense, and industrial applications requiring repeated board exchanges
What is SFM-124-T2-H-D-A-P-TR used for?
The SFM-124-T2-H-D-A-P-TR is used in high-density mezzanine card assemblies, FPGA daughter boards, and rugged embedded computing modules that require 48 signal positions at 0.050 inch pitch with additional vertical clearance between stacked PCBs. Its high-profile housing accommodates tall passive components, heat spreaders, or flex cables routed in the inter-board gap, making it well suited for radar signal processors, communications baseband modules, and industrial machine vision cards. The tape-and-reel packaging supports efficient automated SMT integration in high-volume production.

Frequently Asked Questions
What does the H (high-profile) suffix indicate on SFM-124-T2-H-D-A-P-TR, and when is this height variant necessary?
The H suffix on SFM-124-T2-H-D-A-P-TR designates a high-profile mating height, which increases the board-to-board separation beyond the standard profile of the SFM series—typically by several millimeters. This extra clearance is necessary when components such as electrolytic capacitors taller than 5 mm, inductors, or heat sinks are placed on the host board directly beneath the stacked daughter card. Without the high-profile option, these components would collide with the underside of the daughter board during assembly.
For a dual-channel 6 Gbps serial interface on an FPGA mezzanine card, can SFM-124-T2-H-D-A-P-TR meet the signal integrity requirements?
SAMTEC SFM-series socket strips at 0.050 inch (1.27 mm) pitch are characterized for multi-Gbps differential signal transmission, with insertion loss and return loss performance commonly documented for data rates up to 6 Gbps and beyond in SAMTEC's EDGE Rate and SFM signal integrity reports. For a 6 Gbps dual-channel interface, the 1.27 mm contact spacing provides sufficient room to route 100-ohm differential pairs between adjacent contacts, and the controlled-impedance SMT footprint maintains signal integrity when implemented with SAMTEC's recommended PCB stackup and via recommendations.
How does SFM-124-T2-H-D-A-P-TR's 48-position count compare to SFM-123-02-FM-D-A-P-TR's 46 positions, and when does the extra 2 positions matter?
SFM-124-T2-H-D-A-P-TR provides 48 positions versus 46 on SFM-123-02-FM-D-A-P-TR, a difference of 2 contacts or 4 total mated contacts in the dual-row configuration. Those 2 additional positions matter when the interface protocol requires a contact count that is a multiple of 4 or 8—for example, a 48-bit parallel data bus or 24 differential pairs—where the 46-position variant would leave the bus incomplete. The 48-position option also provides 2 spare contacts for dedicated ground shielding or inter-pair ground stitching at 0.050 inch pitch.
Does the -P suffix on SFM-124-T2-H-D-A-P-TR indicate a specific packaging format, and what does it mean for procurement lead time?
The -P suffix in SAMTEC SFM part numbers typically designates a specific packaging or plating option within the series, while the -TR suffix at the end confirms tape-and-reel delivery. Tape-and-reel parts are generally stocked in larger reel quantities—often 500 to 1000 units per reel—and are prioritized for automated SMT production, which can influence minimum order quantities and stocking strategies. For prototype or low-volume orders requiring fewer than one reel, buyers should confirm tray or cut-tape availability with the distributor, as TR-suffix parts may carry a minimum reel quantity requirement that affects small-batch procurement lead times.
