Product details

8-Position IDC Receptacle for Discrete Wire Harnesses

The 0.098" (2.50mm) pitch is standard across the HR family, keeping the footprint consistent whether you use a 2- or 16-position housing. The black housing and closed-end design prevent wire push-through on the last cavity.

Wiring and Termination — IDC Fit

This works reliably only with the specified 24 AWG wire; a different gauge will either not cut through the insulation or will damage the contact beam. The Tin-Lead contact finish is typical of older JST IDC parts; if your build requires RoHS compliance, check the material declaration for this date code.

Mating and Cross-Reference

The detent lock on the receptacle engages a matching notch on the header. No direct second-source cross is listed; the HR series is JST-proprietary in its IDC variant, so the build locks to the JST header.

Frequently asked questions

What is the mating connector for 08HR-4K?

The 08HR-4K mates with a JST HR series pin header of the same 8-position count and 0.098" (2.50mm) pitch. The header part number shares the 08HR base code with a different suffix.

Is JST 08HR-4K RoHS compliant?

The 08HR-4K carries Tin-Lead contact finish, which typically does not meet RoHS exemption limits for lead. Verify the specific date code against JST's material declaration before specifying for a RoHS-required build.

What wire gauge is compatible with 08HR-4K?

The IDC termination is designed for 24 AWG discrete wire only. Using a different gauge may cause unreliable insulation displacement or contact damage.
