Product details

Board Fit and Routing: 0.100" Pitch, 3-Position Breakaway

The 4-103747-0-03: This is a 3-position, single-row unshrouded breakaway header from TE's AMPMODU Mod II series. The breakaway construction means the strip can be snapped to length, but this part ships as a fixed 3-position piece. The post finish is tin-lead (100 µinch), which wets well during wave solder. The 0.090" insulation height leaves clearance for trace routing under the header body on the top layer.

Mating and Mounting: Unshrouded Push-Pull Interface

No locking latch means the connection relies on friction from the receptacle contacts; for vibration-prone environments, a shrouded header or a secondary retention method is recommended. Through-hole termination with solder posts 0.090" long — the board hole pattern should match the 0.100" row spacing.
