Series Extraction Logic

The handler extracts series using these rules:

•
Standard/SMD LEDs (LS, LW, LA, LY, LB, LR, LG prefix):
- •Extract first 3-4 alphanumeric characters
- •Example: LWE6SG-G4 -> LWE6
•
High-Power LEDs (OSLON, DURIS):
- •Extract up to first space
- •Example: OSLON SSL 80 -> OSLON
- •Example: DURIS E5 -> DURIS
•
RGB LEDs (LRTB, LBCW):
- •Extract first 4 characters
- •Example: LRTB G6SG -> LRTB

Package Code Extraction Logic

The handler extracts package codes based on prefix:

•
LS prefix (Standard): Returns THT
•
SMD LEDs (LW, LA, LY, LB, LR, LG):
- •Strips leading alphanumerics to find suffix
- •Maps suffix to package name using switch statement
•
High-Power LEDs (OSLON, DURIS):
- •Strips series name to find suffix
- •Maps to package (SX, SSL, S5, P3)

Replacement Logic

isOfficialReplacement() returns true when:

•Same series - Both MPNs have the same extracted series
•Color LEDs - Same color code (second character matches for L-prefix)
•OSLON/DURIS - Same series family

java

// 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

Handler Implementation Notes

Known Bugs/Limitations

•
HashSet in getSupportedTypes(): Uses mutable HashSet instead of Set.of()
- •Should be fixed to use Set.of() for immutability
•
Package extraction for high-power LEDs:
- •Uses replaceAll("^[A-Z0-9]+", "") which may not correctly isolate suffix
- •Works for named series (OSLON, DURIS) but may need refinement
•
No optocoupler patterns:
- •OSRAM makes optocouplers but handler only covers LEDs
- •Could add patterns like SFH.* for optocouplers
•
Color temperature not extracted:
- •White LEDs (LW) have CCT variants not currently parsed

Package Code Extraction Quirk

For SMD LEDs, the regex ^[A-Z0-9]+ is used to strip the prefix:

java

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.

Learnings & Quirks

MPN Format Variations

•Some OSRAM MPNs include spaces (e.g., OSLON SSL 80, LR E6SP)
•Handler uses space-aware extraction for series names

Color Code Position

•Second character of L-prefix MPNs indicates color
•Same position used for replacement compatibility check

Package Code Dependencies

•PLCC-6 (G6) typically used for RGB LEDs (needs 6 pads for R, G, B + common)
•PLCC-4 (G4) for single-color SMD LEDs

ams OSRAM Merger

•OSRAM Opto Semiconductors merged with ams in 2021
•Legacy OSRAM part numbers remain valid
•New products may use different naming conventions

No Automotive-Specific Patterns

•Handler doesn't distinguish automotive-grade LEDs
•OSRAM has significant automotive LED portfolio (OSLON Black, Synios)
