Frequently Asked Questions
For a connector with 78 pins, what footprint details should engineers verify before using TFM-139-02-SM-D-RA?
Engineers should confirm the 78 pins layout, mating height, orientation, and PCB land pattern against the SAMTEC drawing before releasing TFM-139-02-SM-D-RA for assembly.
Can TFM-139-02-SM-D-RA support board-to-board signal routing when the design needs 78 pins?
Yes, it is a practical connector choice when the documented 78 pins arrangement matches the mating connector, enclosure clearance, and required signal-routing density.
When replacing TFM-139-02-SM-D-RA, which 78 pins configuration details must purchasing keep unchanged?
Purchasing should preserve the exact 78 pins configuration, SAMTEC suffix, plating or termination option, and date-code traceability so alternates remain mechanically compatible.
