2250506-1 Part Audit

View Document
The part is the Bel / TRP 2250506-1, cross-referenced by Bel as 0826-1X1T-HS-F. It is an active, single-port, tab-up RJ45 MagJack integrated...

flux

Audit complete. The official Bel datasheet URL is set; the 22-terminal count and main transformer pin mapping are valid. Key issues are unnamed LED pins 17–20, ambiguous VC1–VC4 labels, missing pin descriptions, and footprint drill dimensions requiring drawing-level verification.

Fix the VC labels, LED pin names, shield labels, and add pin descriptions.

flux

I’ll correct the VC1–VC4, LED, and shield terminal names from the official Bel drawing, add descriptions to all terminals, then verify the complete 22-pin mapping.

flux

The VC, shield, and description updates are complete. The four LED terminals share an autogenerated placeholder name, so I’m applying a targeted rename using their unique terminal identifiers and then rechecking the symbol.

flux

Updated and verified:
  • VC terminals renamed VC1–VC4
  • Shields renamed SHIELD_S1 / SHIELD_S2
  • Datasheet-backed descriptions added to all 22 terminals
  • Pin numbers, positions, types, and footprint mappings preserved
Open item
  • LED pins 17–20 now have correct polarity/color descriptions, but their shared ~ labels could not be individually renamed due to a terminal-renaming limitation. Intended names are LED1_YELLOW_K, LED1_YELLOW_A, LED2_ORANGE_A_GREEN_K, and LED2_ORANGE_K_GREEN_A.
