Frequently Asked Questions
Before committing TFM-139-04-L-D-LC, which mechanical values must match the PCB?
TFM-139-04-L-D-LC is a high-reliability tiger eye terminal strips, .050" pitch from SAMTEC for production PCB assemblies. Key specs include 78 pins, 0.050 inch pitch and active lifecycle support. Request current stock, quoted pricing, and worldwide shipping through FindMyChip. Review the assembly at 23 °C and match position count, pitch, row layout, mounting orientation, and mated height to the released PCB and connector drawings.
Which first-article checks are useful for TFM-139-04-L-D-LC deliveries?
At 23 °C, compare TFM-139-04-L-D-LC marking and full suffix with the purchase order, then inspect contacts, coplanarity, housing keys, packaging, and continuity before lot acceptance.
Can a nearby TFM-139-04-L-D-LC ordering suffix be substituted without validation?
No; mate a TFM-139-04-L-D-LC prototype pair at 23 °C and confirm termination style, plating option, polarization, retention, clearance, and electrical continuity before approving any substitution.
