Right-Angle Board Lock Header for Dynamic D-3200
The 1-178138-2: It uses a 5.08 mm pitch, which gives the board footprint room for higher voltage (rated 600 V) and keeps the per-contact current path well within the housing's thermal limits. The shrouded 4-wall housing and detent lock provide alignment and vibration resistance during mating.
Sourced through independent distribution; quantities and lead time confirmed at RFQ against your BOM line.
Peer Header Comparison
Compared to the 1-1871673-2, a 4-position dual-row header with 2.50 mm pitch and tin mating finish, this 1-178138-2 offers a wider 5.08 mm pitch and gold contacts — a better fit for higher-voltage or higher-cycle applications where the tin sibling would fret over time. The 1376779-2 is a 3-position header with gold mating contacts but 8.00 µinch thickness — thinner than the 15.0 µinch on this part, meaning fewer mating cycles before wear-through.
