Brand ULO - ULO |
Model HC502 - 19-contact HDMI SMT socket |
Colour B - Black |
Shell Plating 6 - Tin |
Contact Plating 0 - Selective gold flash |
ULO-HC502 and ULO-HC503 are 19-contact HDMI female sockets with SMT signal tails and four through-board shell-retention tabs. HC502 is the socket configuration without an upright bracket; HC503 adds an upright bracket with an M3×0.5 threaded hole.

Working voltage, current rating and reflow profile are unspecified. HDMI version, bandwidth and supported video formats are unspecified.
The ordering sequence for each model is insulator colour, shell plating and contact plating.
| Field | Code | Option |
|---|---|---|
| Insulator colour | B | Black |
| Shell plating | 6 / N | Tin / nickel |
| Contact plating | 0 | Selective gold flash |
| Contact plating | C | Selective 3µin gold |
| Contact plating | 1 | Selective 10µin gold |
Both model drawings specify the same pad and shell-slot dimensions below. The signal pads are surface-mounted; the four elongated slots receive the shell tabs. Dimension values are in millimetres.

| Shell-slot centre span across the board | 14.5 |
| Shell-slot width | 0.9, four slots |
| Rear / front slot lengths | 2.7 / 2.1 |
| Rear-to-front slot-centre spacing | 5.96 |
| Board-edge-to-rear-slot-centre reference | 9.55 |
| Pad-end-to-rear-slot-centre reference | 2.06 |
| PCB layout tolerance | ±0.05 |
HC502 has a 15mm overall width, 12.15mm body-depth reference and 6.23mm side-profile height. Its front drawing gives 14mm and 10.8mm nested width references, a 4.55mm opening-height reference, and 9mm and 8mm contact-row spans. Individual tail width is 0.2mm, compared with the recommended 0.28mm PCB pad width. Shell-foot section widths are 1mm and 2mm, with 4.59mm and 5.96mm longitudinal references.
HC503 retains the four-slot PCB pattern and adds an upright mounting bracket. The overall width is 15mm; the top-view body-depth reference is 12.16mm. Side-profile references are 15.61mm including the bracket and 6.22mm at the socket. The threaded-hole centre is 9.97mm above the indicated front-view reference line. The front view also gives a 14.5mm shell-foot span and 4.55mm opening-height reference; longitudinal shell-foot references are 4.59mm and 5.96mm.
