Frequently Asked Questions
Which designs should use TSM-139-04-TL-DV-P-TR when 78 pins is required?
TSM-139-04-TL-DV-P-TR is useful when the BOM needs a Connector matching the approved board-to-board or cable-to-board interconnect design. The available part context includes 78 pins, giving engineers a concrete parameter for datasheet and substitution checks.
How should layout teams verify 78 pins before approving TSM-139-04-TL-DV-P-TR alternates?
For layout review, compare the approved Other footprint, assembly method, and manufacturer documentation before substituting. Keeping 78 pins visible helps avoid alternates that change routing, mating fit, or assembly qualification evidence.
What RFQ checks keep TSM-139-04-TL-DV-P-TR aligned with the 78 pins requirement?
For RFQs, quote the exact TSM-139-04-TL-DV-P-TR, SAMTEC manufacturer name, lifecycle expectations, and traceability needs. Supplier responses should preserve 78 pins or clearly explain any proposed alternate before purchase approval.
