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.","metaTitle":"JST 08HR-4K HR Series Receptacle, 8 Pos, 2.50mm, IDC","metaDescription":"JST 08HR-4K HR series 8-position IDC receptacle, 0.098\" (2.50mm) pitch, 24 AWG, Tin-Lead contacts, detent lock.
