Thought for 13 sec

No results for BB134 varactor diode SOD-323.

Found 2 results for BB134.

Read "Extract the package text and source/part URLs visible for VD1 BB134, VD2 MM3Z3V0T1G, DD1 MAX1472, and BQ1 if present. Return the visible text exactly where readable." in img-cdn.flux.ai.

Read "Extract the package text and source/part URLs visible for VD1 BB134, VD2 MM3Z3V0T1G, DD1 MAX1472, and BQ1 if present. Return the visible text exactly where readable." in img-cdn.flux.ai.

Thought for a moment

Those screenshots do help.
What I confirmed from them:
  • VD1 is indeed intended as BB134
  • VD1 package text shown is “SMD variable-capacitance diode (SOD-323)”
  • VD2 row shows MM3Z3V0T1G
  • DD1 row shows MAX1472AKA+T
  • The screenshot source text for BB134 points to an external marketplace listing, not a clean library-backed part source
What I already completed in the project before this:
  • Recreated the schematic from the screenshots
  • Corrected BOM values including:
    • R4 = 3.3k
    • RV1 = 3386P-1-102LF (1k trimmer)
    • VD2 = MM3Z3V0T1G
  • Rewired replaced parts
  • Verified ERC was clean in the checked categories
  • Updated Screenshot Recreation Notes
What still remains:
  • VD1 is still a substitute in the project, not the exact BB134
  • I confirmed the BOM/package text for BB134, but I did not complete the final replacement in this pass
  • The library search I ran did not immediately surface a clean BB134 part entry, so the next step would be:
    1. try a broader semantic part search for BB134 / equivalent varactor
    2. if found, replace VD1 and preserve wiring
    3. if not found, keep the current substitute and update the notes to reflect that the BOM/package were confirmed but the exact part is unavailable in-library
So current status is:
  • Schematic recreation is intact
  • Most BOM corrections are already applied
  • Only the exact VD1 BB134 replacement is still unresolved
Find BB134 equivalent
Document VD1 substitute
Run ERC/DRC
Check BB134 datasheet
