Frequently Asked Questions

What stacking height and pin count does SEAF-20-05.0-L-08-2-A-K-TR provide for board-to-board designs?

SEAF-20-05.0-L-08-2-A-K-TR provides a 20-position interface with an 8.00 mm mated stacking height, giving designers precise board spacing and 20 signal channels on a 5.00 mm column pitch footprint.

How does the contact plating on SEAF-20-05.0-L-08-2-A-K-TR contribute to long-term connector reliability?

The mating contacts feature 10 µin gold over 50 µin nickel plating, which minimizes contact resistance and resists corrosion over hundreds of insertion cycles, while the nickel barrier on tin terminations prevents tin whisker growth at solder joints.

Is SEAF-20-05.0-L-08-2-A-K-TR designed for automated SMT assembly and tape-and-reel feeding?

Yes. The TR suffix confirms tape and reel packaging compatible with standard pick-and-place machines, and the SMT termination style supports standard reflow profiles up to 260°C for high-volume manufacturing.

What procurement lead time and RoHS status apply to SEAF-20-05.0-L-08-2-A-K-TR?

According to distributor data, SEAF-20-05.0-L-08-2-A-K-TR carries a 1-week factory lead time and is RoHS-compliant (Pb-free code: Yes), making it a fast-turn and globally compliant choice for new PCB designs needing 20-position stacking connectivity.
