A: The Terminal Position Assurance (TPA) slot is designed for an optional retainer that acts as a secondary lock. The retainer cannot be fully inserted if the female crimp terminal is only partially loaded. This structure ensures that assembly operators seat the terminal completely into the housing, preventing terminal back-outs in high-vibration environments.

A: Yes. Although the Nano-Fit series is engineered for high current density (up to 6.5A per circuit), its 2.5 mm pitch layout allows it to function as a dense hybrid interface. Engineers frequently utilize this 16-circuit configuration to route both low-frequency control signals and low-voltage power lines within a single wire harness.

A: Suzhou Suqin provides comprehensive B2B component support. Beyond supplying the original 105308-1216 housings, we source matching female crimp contacts, TPA retainers, and headers. We maintain steady warehouse stock profiles to support scheduled production releases and offer complete custom wire harness manufacturing services based on customer drawings.
