Model UC488 - Upright six-contact interface with through-hole PCB mounting |
Housing Colour B - Black |
Shell Plating N - Nickel |
Contact Plating C - Selective gold 3µin |
UC488 and UC489 are six-contact IEEE 1394 female PCB connectors with through-hole signal contacts. UC488 places the mating interface upright in a narrow outline; UC489 places it horizontally in a wider, lower outline. Both provide a right-angle mating direction relative to the PCB. Select the footprint and current rating by model.
| Characteristic | UC488 | UC489 |
|---|---|---|
| Interface | IEEE 1394; 6 contacts; female | |
| Mating-face orientation | Upright | Horizontal |
| Rated current | 1.5A | 0.5A |
| Rated voltage | 30V; AC/DC designation unspecified | |
| Contact resistance | ≤50mΩ | |
| Insulation resistance | 100MΩ; minimum/maximum designation unspecified | |
| Dielectric withstand test | 100VAC for 1 minute | |

The dielectric test condition is separate from the rated voltage. The interface designation does not specify a supported data rate or protocol revision.
Three fields follow each model code: housing colour, shell plating and contact plating.
| Selection | Code | UC488 and UC489 |
|---|---|---|
| Housing colour | B | Black |
| Shell plating | N | Nickel |
| 6 | Tin | |
| Contact plating | C | Selective 3µin gold |
Dimensions are in millimetres. The front view shows the six mating contacts in two columns of three. The dimensional drawing gives the formed terminal arrangement but does not provide a separate recommended PCB drilling pattern.
