Frequently Asked Questions
Which design checks matter most when selecting SQT-128-01-LM-D for board-to-board interconnects?
SQT-128-01-LM-D is suited to mezzanine boards, industrial controllers, instrumentation modules, communications equipment, and rugged embedded hardware when the design needs 56 pins. Confirm 56 pins, 2.00mm pitch, -55°C to 125°C against the manufacturer drawing before PCB release.
Which receiving checks help confirm SQT-128-01-LM-D against the approved drawing?
Procurement should verify lifecycle status, datasheet revision, approved manufacturer, and 56 pins against the BOM. This keeps substitutions controlled before allocation, inspection, or worldwide shipping.
How can a buyer judge whether SQT-128-01-LM-D is a drop-in candidate?
Compare nearby SAMTEC variants by footprint, electrical limits, mating geometry, and 56 pins. Choose SQT-128-01-LM-D only when 56 pins, 2.00mm pitch, -55°C to 125°C matches the approved assembly process.
