What are the key features of SEAF-20-05.0-S-06-2-A-K-TR?

20-position single-row board stacking plug with precisely controlled 5.0mm stack height for accurate PCB-to-PCB spacing
Gold (30µin) over nickel (50µin) mating contact finish ensures low-resistance, corrosion-resistant connections through thousands of mating cycles
Peg board mounting option provides additional PCB retention during reflow soldering and in high-vibration end-use environments

What is SEAF-20-05.0-S-06-2-A-K-TR used for?

The SEAF-20-05.0-S-06-2-A-K-TR board stacking plug is used in mezzanine card assemblies, SBC expansion modules, and embedded computing platforms where a controlled 5.0mm stack height between PCBs is required. Its 20-position single-row layout supports moderate signal counts in compact stacking configurations for telecommunications, industrial control, and data acquisition systems. The tape-and-reel packaging facilitates high-volume automated assembly on SMT lines.

Frequently Asked Questions

What does the 5.0mm stack height specification mean for PCB designs using the SEAF-20-05.0-S-06-2-A-K-TR?

The 5.0mm stack height defines the precise distance between the two PCB surfaces after mating, accommodating through-hole components, heatsinks, or other features in that 5.0mm gap. Designers can rely on this controlled dimension to plan component placement on both boards without clearance conflicts.

How does the peg board mounting option benefit the SEAF-20-05.0-S-06-2-A-K-TR in reflow soldering?

The peg mounting feature adds mechanical anchors that insert into PCB holes, holding the 20-position connector body in position during conveyor reflow soldering at temperatures up to 260°C. This prevents shifting or floating of the connector on the solder paste before joints solidify, improving first-pass yield on automated SMT lines.

For which signal density requirements is the 20-position single-row SEAF connector a suitable mezzanine solution?

The 20-position single-row layout supports up to 20 signal or power lines across a 1.229-inch body length at the standard SAMTEC pitch. It suits medium-density mezzanine interfaces such as SPI, I2C, UART, GPIO buses, and mixed signal-power combinations in embedded modules where a compact single-row footprint is preferred over bulkier dual-row alternatives.
