Frequently Asked Questions
How does TST-128-02-L-D fit dense board-to-board signal routing?
TST-128-02-L-D provides 56 positions in a SEARAY open-pin-field connector, giving designers a compact .050 in pitch interface for mezzanine, communications, and embedded boards.
Which assembly planning detail matters for this SAMTEC SEAM ordering code?
The production ordering configuration helps buyers plan SMT production, while the 56-position connector format supports feeder setup, placement review, and board-level interconnect count.
What should buyers verify before substituting another SAMTEC SEARAY connector?
Check the required 56 positions, .050 in pitch, mating height, plating option, and reel format before approving an alternate, because nearby SEAM variants can differ mechanically.
