The Hirose TM30P-66P is a 6-position, 6-conductor (6p6c) IDC plug from the TM-P series, designed for flat oval cable with stranded wires. The translucent polycarbonate housing lets you inspect the IDC termination visually — useful when you're building a harness and want to confirm each conductor is seated before the housing snaps closed. Gold-plated contacts give it the corrosion resistance you'd expect for repeated mating in a controlled environment, though the IDC termination itself is a one-shot deal: once you punch down, there's no rework.
Sourcing Reality — Last Buy Status
This part is on Last Buy status — the manufacturer has ended regular production, and the remaining stock in the channel is the final run. If you need TM30P-66P for a BOM line, the window to buy is narrowing. There is no official replacement order code from Hirose, so if you are planning a design refresh, you will need to evaluate a 6p6c IDC plug from another series or manufacturer that matches the same footprint and cable type.
