Frequently Asked Questions
How many positions does the SFM-149-L2-F-D-A-P-TR have, and what is its row pitch configuration?
The SFM-149-L2-F-D-A-P-TR has 98 total positions arranged in 2 rows of 49, with a 0.050" (1.27 mm) centerline pitch between adjacent contacts. This dual-row layout at fine pitch allows engineers to pack 98 signal or power lines into a compact SMT footprint. The 1.27 mm pitch is half the spacing of standard 0.100" connectors, enabling significantly denser PCB interconnects in space-critical designs.
What current and temperature specifications make the SFM-149-L2-F-D-A-P-TR suitable for industrial and defense boards?
Each contact of the SFM-149-L2-F-D-A-P-TR is rated for 1 A continuous current, sufficient for signal lines and light power distribution. The connector is specified for an operating temperature range of -55°C to +125°C, covering MIL-spec temperature zones for defense avionics and harsh industrial environments. Gold-plated contacts maintain consistent electrical performance even after extended thermal cycling across this full temperature range.
Does the SFM-149-L2-F-D-A-P-TR support automated SMT assembly, and what does its TR suffix mean for production?
Yes, the TR suffix designates tape-and-reel packaging, making the SFM-149-L2-F-D-A-P-TR directly compatible with automated pick-and-place SMT assembly equipment. Each reel holds multiple connectors in sequence for uninterrupted feeder operation during high-volume PCB production runs. The surface mount termination style supports standard reflow soldering, eliminating manual insertion and reducing placement errors for this 98-pin dual-row connector.
What Samtec mating plug series pairs with SFM-149-L2-F-D-A-P-TR for a complete 0.050" pitch dual-row board-to-board interconnect?
The SFM series socket strips mate with Samtec's corresponding 0.050" pitch dual-row plug headers such as the TSM or SMM series, completing a 98-position board-to-board stack at 1.27 mm pitch. Stack height depends on the specific mating header selected and can range from approximately 4 mm to over 20 mm, giving designers flexibility for varying PCB separation requirements. Both connector halves are available in tape-and-reel packaging to support fully automated assembly on both mating boards.
