Model UC499 - Through-hole four-contact PCB socket |
Housing Colour B - Black |
Shell Plating N - Nickel |
Contact Plating 0 - Selective gold flash |
UC499 and UC500 are metal-shelled female PCB sockets with a keyed rectangular mating opening and four contacts. UC499 uses through-hole contacts and four shell mounting slots. UC500 has surface-mount contact tails and four flat shell tabs. Choose the mounting arrangement and current rating for the intended assembly, then compare the mating profile and dimensional references.
| Characteristic | UC499 | UC500 |
|---|---|---|
| Contacts | 4 | 4 |
| PCB mounting | Through-hole | SMT |
| Rated current | 1.5A | 0.5A |
| Rated voltage | 30V; AC/DC designation unspecified | 30V; AC/DC designation unspecified |
| Contact resistance | ≤50mΩ | ≤50mΩ |
| Insulation resistance | 100MΩ; minimum/maximum designation unspecified | 100MΩ; minimum/maximum designation unspecified |
| Dielectric withstand test | 100VAC for 1 minute | 100VAC for 1 minute |
| Insulator | PA66; material group I; UL94V-0 | PA66; material group I; UL94V-0 |
| Contact material | Copper alloy | Copper alloy |
The current rating is model-specific. No USB generation, data rate or protocol compatibility is specified for these sockets. The 100VAC value is a dielectric test condition, separate from the 30V rating.
The three fields after UC499 or UC500 are housing colour, shell plating and contact plating. Mounting is determined by the selected model.
| Field | Code | Selection |
|---|---|---|
| Housing colour | B | Black |
| Shell plating | N / 6 | Nickel / tin |
| Contact plating | 0 / C | Selective gold flash / selective gold 3µin |
The contact tails are on 0.80mm centres before forming. The PCB signal holes use a staggered two-column pattern; the 2mm column spacing is a different dimension from the tail pitch.
| Reference | Dimension |
|---|---|
| Longitudinal outline reference | 12.60mm |
| Front outer width | 8.50mm |
| Mating-profile references | 5.45mm width; 3.02mm and 3.55mm vertical references |
| Side height reference | 5.94mm |
| Contact tail pitch / total span | 0.80mm / 2.40mm |
| Additional front references | 1.15mm contact-level offset; 8mm lower-body width |
| Side tail and retention references | 3mm and 2.60mm |
| PCB signal holes | Four Ø0.70mm holes, +0.05mm diameter tolerance |
| Signal-hole arrangement | 2mm between columns; 1.60mm between holes in each column; 0.80mm stagger between columns |
| Shell mounting slots | Four 2.50×1mm slots |
| Shell-slot pad envelope | 4×3.20mm |
| Shell-slot centre pattern | 4.70×8mm |
| Lateral PCB references | 3.50mm from PCB-edge reference to first slot centre; 4.35mm from first slot centre to first signal column |
| PCB layout tolerance | ±0.05mm |

| Front outer width | 8.50mm |
| Mating-profile references | 5.45mm width; 3.02mm and 3.55mm vertical references |
| Front contact-level offset | 1.15mm |
| Contact tail pitch / total span | 0.80mm / 2.40mm |
| Side height reference | 5.80mm |
| Front projection reference | 2mm |
| Side terminal reference | 6mm |
A complete recommended SMT pad pattern is unspecified for UC500. Its flat shell tabs and formed contact tails require a different footprint from the UC499 through-hole pattern.
