Use when refactoring, cleaning up, or enhancing the lib-electronic-components codebase. Provides guidance on architecture patterns, known issues, duplication hotspots, and recommended improvements.
Base skill for working with electronic components in this library. Use when adding new component types, manufacturer handlers, or working with MPN (Manufacturer Part Number) operations, BOM entries, or component classification.
Use this skill BEFORE creating a PR to ensure all documentation, skills, and learnings are updated. Critical for preserving institutional knowledge and preventing documentation drift.

OSRAM Opto Semiconductors (now part of ams OSRAM) is a leading manufacturer of:
OSRAM LEDs follow a structured naming convention:

The handler extracts series using these rules:
Standard/SMD LEDs (LS, LW, LA, LY, LB, LR, LG prefix):
LWE6SG-G4 -> LWE6High-Power LEDs (OSLON, DURIS):
OSLON SSL 80 -> OSLONDURIS E5 -> DURISRGB LEDs (LRTB, LBCW):
LRTB G6SG -> LRTBThe handler extracts package codes based on prefix:
LS prefix (Standard): Returns THT
SMD LEDs (LW, LA, LY, LB, LR, LG):
High-Power LEDs (OSLON, DURIS):
isOfficialReplacement() returns true when:
// Same color, same series = replacement
"LR E6SP-G4" vs "LR E6SP-G6" // Both red, same series -> true
"LW E6SG-G4" vs "LR E6SG-G4" // Different colors -> false
// High-power same family
"OSLON SSL 80" vs "OSLON SSL 150" // Both OSLON SSL -> true

HashSet in getSupportedTypes(): Uses mutable HashSet instead of Set.of()
Set.of() for immutabilityPackage extraction for high-power LEDs:
replaceAll("^[A-Z0-9]+", "") which may not correctly isolate suffixNo optocoupler patterns:
SFH.* for optocouplersColor temperature not extracted:
For SMD LEDs, the regex ^[A-Z0-9]+ is used to strip the prefix:
String suffix = mpn.replaceAll("^[A-Z0-9]+", "");
This removes ALL leading alphanumerics, leaving only the package suffix if separated by a hyphen or if it starts with a non-alphanumeric. For MPNs like LWE6SG-G4, the hyphen separates the suffix properly.
