A latch holder on the header locks with the matching RAST 5 receptacle housing, giving positive retention against cable pull and vibration. The -40°C to 120°C operating range covers the thermal profile inside most enclosed equipment. ## What mates with this header This header mates with RAST 5 receptacle housings that accept 5.00 mm pitch tab contacts. The 5.00 mm pitch of 4-1971895-3 gives more room between contacts for creepage and routing, while the latch holder provides a different retention feel. If your board footprint is set for 5.00 mm, 1-2232960-3 will not fit — the pitch difference is a board-spin decision.","metaTitle":"TE Connectivity 4-1971895-3 RAST 5 Header 3 Pos 5mm","metaDescription":"TE Connectivity AMP Connectors 4-1971895-3 RAST 5 header, 3 positions, 5.00mm pitch, tin contacts, latch holder, UL94 V-0.
