3-position RAST 5 header — board-to-wire with a latch
The 4-1971895-3: This is a TE Connectivity AMP Connectors RAST 5 header, 3 positions, single row, 5.00 mm pitch, designed for board-to-cable/wire applications. 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.
