What are the key features of SFM-149-02-ZZ-D-A-K-TR?
- 98-position dual-row fine-pitch socket strip with 1.27 mm (0.050 inch) pitch enabling ultra-high-density SMT board-to-board connections with 49 pins per row
- High reliability surface mount construction with SMT solder retention for secure attachment in demanding industrial and computing applications
- Dual-row socket design compatible with SAMTEC SFM series mating headers for versatile high-density connector system configurations
What is SFM-149-02-ZZ-D-A-K-TR used for?
The SFM-149-02-ZZ-D-A-K-TR 98-position socket strip is designed for ultra-high-density board-to-board interconnect in FPGA development boards, high-speed data acquisition systems, and compute module carrier boards that require a large number of fine-pitch signal connections in a compact SMT footprint. Its 1.27 mm pitch dual-row configuration supports dense GPIO, memory bus, and high-speed serial signal routing across mezzanine board stacking configurations. This connector is commonly specified in telecommunications line cards, network processing units, and test and measurement platforms where 98-pin fine-pitch connectivity is required.

Frequently Asked Questions
How many total contacts and what pitch does the SFM-149-02-ZZ-D-A-K-TR provide for high-density interconnect?
The SFM-149-02-ZZ-D-A-K-TR provides 98 total positions in a dual-row configuration at 1.27 mm (0.050 inch) pitch, with 49 pins per row. This fine-pitch layout achieves more than twice the pin density of standard 2.54 mm pitch connectors, enabling 98 signal contacts in a PCB footprint approximately equal to a 49-position 2.54 mm pitch single-row connector.
For an FPGA mezzanine board design, why is the SFM-149-02-ZZ-D-A-K-TR preferred over multiple smaller socket strips?
FPGA mezzanine boards with high I/O counts benefit from a single 98-position SFM-149-02-ZZ-D-A-K-TR because it provides 98 signal contacts at 1.27 mm pitch in one housing, eliminating the mechanical misalignment risk and additional PCB area associated with multiple smaller connectors. A single 98-position strip also simplifies BOM management and ensures consistent mating force across all 98 pins compared to using 2 or more separate 49-position sockets.
In what procurement scenarios should engineers specify the tape-and-reel packaged SFM-149-02-ZZ-D-A-K-TR versus tray packaging?
The tape-and-reel (TR suffix) SFM-149-02-ZZ-D-A-K-TR is the preferred procurement format for automated SMT production lines handling volumes of 1000 or more units, as standard pick-and-place machines require 1.27 mm pitch SMT connectors in reel format for consistent feeder loading. For low-volume prototyping or manual assembly of fewer than 100 units, a tray-packaged variant may reduce handling costs, but the TR format provides the best cost-per-unit pricing at high volume.
