Frequently Asked Questions
How does SQT-139-03-H-D fit a 78-pin board-to-board interconnect layout?
SQT-139-03-H-D provides 78 pins on a standard-pitch pitch terminal-strip format, so it suits mezzanine links, programming headers, and signal breakout boards that need repeatable SMT assembly.
Which assembly choice supports 78 pins on a horizontal SMT layout for SQT-139-03-H-D?
The surface-mount horizontal configuration keeps the connector profile predictable while giving 78 pins for signal routing, board stacking, or test access in compact PCB layouts.
What should buyers verify before substituting a 78-pin SAMTEC TSM variant?
Confirm 78 pins, the same 78-position count, standard-pitch pitch, plating suffix, tail style, and tape-and-reel or tube packaging before replacing SQT-139-03-H-D in an approved BOM.
