A3963 3.96 mm wire-to-board connectors combine housings, board headers and crimp terminals for compact harness assemblies. The formats cover 2–15 circuits and 26–18 AWG wire. Electrical ratings vary by component role, so the selected housing, header and terminal must be checked separately.
| Component | Selection point |
|---|---|
| H housings | Nylon 66 single-row housings for the required circuit count |
| Board headers | Brass-contact board interfaces by orientation and footprint |
| Crimp terminal | Phosphor bronze contact for 26–18 AWG wire |
| Centerline | 3.96 mm |
|---|---|
| Positions | 2–15 |
| Rows | Single row |
| Operating temperature | -25 °C to 105 °C |
| UL file | E364711 |
| Maximum current per contact | 10 A / 3 A (model-dependent options) |
| Maximum voltage | 250 VAC/DC |
| Contact plating | Tin Plating |
| Housing resin / flammability | Nylon 66 UL94V-0 |
Match the housing and header by circuit count and board geometry, then select the terminal for the conductor size. Confirm the current and voltage values on the applicable component drawing.
