Key Features
- 40-position dual-row polarized female socket with tall mating height (H variant) providing additional board clearance for components on mating boards
- Polarized housing ensuring error-free mating orientation for the 40-position dual-row 1.27 mm pitch connector in complex multi-board assemblies
- Gold with nickel barrier termination contact finish delivering excellent solderability and long-term solder joint reliability during reflow assembly
- Tape-and-reel (TR) packaging supporting automated pick-and-place SMT assembly for high-volume production of board-to-board interconnect applications
Applications
The SFM-120-02-H-D-P-TR is used in high-density board-to-board and daughter-card socket applications where a 40-position dual-row 1.27 mm pitch polarized female connector with tall mating height is needed to accommodate components on the mating header board. It is commonly deployed in embedded computing modules, industrial control cards, and test and measurement equipment where the polarization feature prevents mis-mating damage during assembly or field service. The tape-and-reel format makes it well suited for automated high-volume SMT production of FPGA expansion boards, signal conditioning modules, and communication interface cards requiring reliable 40-position mezzanine connectivity.

Frequently Asked Questions
What is the contact pitch, pin count, and row configuration of the SFM-120-02-H-D-P-TR?
The SFM-120-02-H-D-P-TR has 40 positions in a dual-row configuration with a 0.050-inch (1.27 mm) pitch, providing 40 female contacts for board-to-board mating in a surface-mount polarized socket that prevents incorrect insertion orientation during PCB assembly and field maintenance.
Why does the SFM-120-02-H-D-P-TR use a tall (H) mating height variant and when is this needed?
The tall mating height (H) variant provides additional vertical clearance between the two mated PCBs, accommodating taller SMD components such as electrolytic capacitors, transformers, or heat sinks on the surface of the mating header board. This prevents mechanical interference in designs where 40-position dual-row connectors must mate across boards with tall on-board components within a limited enclosure height.
How does the polarization feature of the SFM-120-02-H-D-P-TR improve assembly reliability?
The polarization feature uses a keyed housing that physically blocks incorrect mating of the 40-position dual-row connector, ensuring that the mating header can only be inserted in the correct orientation. This prevents reversed connections that could damage ICs or signal lines, which is particularly valuable in multi-connector backplane assemblies or high-density rack systems where visual identification of orientation is difficult.
Is the SFM-120-02-H-D-P-TR compatible with standard reflow soldering and what is the typical lead time?
Yes, the SFM-120-02-H-D-P-TR uses surface-mount termination with gold-over-nickel barrier contacts that are compatible with standard SMT reflow soldering processes up to 260°C peak temperature, and the tape-and-reel packaging supports automated pick-and-place assembly. The typical factory lead time is 3 weeks, which should be factored into procurement planning for production builds.
