Key Features
- 88-position dual-row design on 1.27 mm (0.050-inch) pitch for dense board-to-board signal routing in compact SMT assemblies
- Gold-plated high-reliability micro-terminal contacts rated for 200+ mate-unmate cycles with stable sub-20 milliohm contact resistance
- SMT termination compatible with standard lead-free reflow up to 260°C, enabling high-volume automated assembly without through-hole drilling
Applications
The SFM-144-02-H-D-A-K suits high-density board-to-board interconnect applications in telecommunications line cards, FPGA mezzanine modules, and industrial backplane systems where 88 signals must transfer across a 1.27 mm pitch interface with minimal footprint. Its surface-mount design integrates seamlessly into automated SMT production lines, reducing assembly steps compared to through-hole alternatives. The high-reliability gold contacts also make it appropriate for rugged embedded computing platforms subject to vibration and thermal cycling.

Frequently Asked Questions
What are the key electrical specifications of the SFM-144-02-H-D-A-K, including contact resistance and current rating?
The SFM-144-02-H-D-A-K provides 88 contacts on a 1.27 mm pitch with gold-plated terminals offering contact resistance below 20 milliohms. Each contact is rated to carry up to 1 A continuous current, making it suitable for mixed signal and power distribution across board-to-board interfaces in compact electronic assemblies.
How does the 88-position dual-row SFM-144-02-H-D-A-K compare to a 94-position SFM-147 variant when selecting for a specific application?
The SFM-144-02-H-D-A-K offers 88 pins versus the 94 pins of the SFM-147 series, making it the preferred choice when the signal count fits within 88 positions and a slightly shorter connector length is needed. The 6-position reduction trims roughly 3.8 mm off the connector body at 1.27 mm pitch, which can matter in ultra-compact mezzanine card designs.
Is the SFM-144-02-H-D-A-K suitable for use in FPGA mezzanine card applications operating at high data rates?
Yes, the SFM-144-02-H-D-A-K is commonly used in FPGA mezzanine and FMC-compatible card designs where 88 signals at 1.27 mm pitch provide adequate density for multi-gigabit differential pairs. The controlled-impedance SMT footprint supports signal frequencies exceeding 3 GHz per differential pair when the PCB stack-up is properly designed with 100-ohm differential trace routing.
What reflow soldering conditions does the SFM-144-02-H-D-A-K support, and how many reflow passes can it withstand?
The SFM-144-02-H-D-A-K is rated for lead-free reflow soldering at peak temperatures up to 260°C, conforming to IPC/JEDEC J-STD-020 MSL requirements. The connector body withstands up to 3 reflow passes without mechanical distortion, giving manufacturers flexibility for double-sided SMT assembly processes common in high-density board production.
