Frequently Asked Questions
How does the 86-position count of the TFM-143-02-H-D-LC compare to lower-count TFM variants for signal-dense designs?
The TFM-143-02-H-D-LC provides 86 contacts on a 0.050-inch (1.27 mm) pitch dual-row footprint, making it one of the higher-density options in the TFM series. Compared to 12- or 31-position variants, the 86-pin version consolidates more signal lines into a single connector, reducing PCB connector count and simplifying harness routing in data-intensive embedded designs.
What current and voltage rating applies per contact in the TFM-143-02-H-D-LC and what does this mean for power distribution?
Each of the 86 contacts in the TFM-143-02-H-D-LC is rated for 3A and 125V AC/DC. While primarily intended for signal connections, this per-pin rating permits selective use of contact pairs for low-power distribution alongside signal lines in a single 0.050-inch pitch connector without exceeding thermal derating limits.
Which procurement considerations apply when sourcing the TFM-143-02-H-D-LC for a production build?
When ordering the TFM-143-02-H-D-LC, buyers should confirm SMT reel availability for automated assembly and verify PCB land pattern compatibility with the 0.050-inch (1.27 mm) pitch dual-row, 86-pin footprint. Lead time and minimum order quantities from authorized SAMTEC distributors typically vary, so confirming stock levels and alternate configurations like tape-and-reel packaging is advisable for volume procurement.
