Handler Implementation Notes
Mounting Type Detection
The handler includes a getMountingType() helper method:
// Through-hole components
"333-?" prefix -> "Through-hole"
"IR333", "IR908" -> "Through-hole"
"PT333", "PT908" -> "Through-hole"
// SMD components
"XX-XX" pattern -> "SMD"
"ELSH-", "EL-SSD", "SHWO", "EASP" -> "SMD"
"ALS-PT", "PT19-21" -> "SMD"
// DIP for optocouplers
"EL817", etc. without S1/S2/G -> "DIP"
"EL817S1" with S1/S2/G -> "SMD"
Product Category Detection
The handler includes a getProductCategory() helper:
| Pattern | Category |
|---------|----------|
| XX-XXX.*RGB.* | RGB LED |
| XX-XX[A-Z].* | SMD LED |
| 333-?[A-Z].* | Through-hole LED |
| ELSH-.* | High-power SMD LED |
| SHWO.*, EASP.* | High-power LED |
| IR[0-9]{3}.* | Infrared LED |
| PT[0-9]{2,3}.* | Phototransistor |
| EL[0-9]{3,4}.* | Optocoupler |
| ALS-PT.* | Light Sensor |
| ELS-.* | Seven-segment Display |
Color Extraction
The handler extracts LED colors from MPNs:
"RGB" in MPN -> "RGB"
"SURC", "SRC", "URC", "-R" -> "Red"
"SUGC", "SGC", "UGC", "-G" -> "Green"
"SUBC", "SBC", "UBC", "-B" -> "Blue"
"SUYC", "SYC", "UYC", "-Y" -> "Yellow"
"SUOC", "SOC", "UOC", "-O" -> "Orange"
"SUWC", "SWC", "UWC", "-W" -> "White"

Learnings & Quirks
General Notes
- No manufacturer-specific ComponentTypes: Unlike TI/ST, Everlight uses generic
LEDandICtypes - OPTOCOUPLER_TOSHIBA reuse: Everlight optocouplers use the Toshiba optocoupler type since a generic optocoupler type doesn't exist
- Size code pattern: Everlight uses XX-XX format (e.g., 17-21) for SMD packages which maps to standard sizes
- Phototransistors dual-typed: Registered under both
LEDandICcomponent types
MPN Parsing
- Slash separators: Everlight MPNs use
/to separate sections (size/color/brightness/packing) - Color in MPN: Color code appears directly after size code, not as a suffix
- Brightness bins: The S530, C530 codes after color indicate brightness binning
- Color bins: A3, A4 codes after brightness indicate color temperature binning
Package Extraction
- SMD size code mapping: Must handle the Everlight-specific size codes (17-21 -> 0603)
- Through-hole sizes: IR/PT 333 = 3mm, 908 = 5mm (note: 908 is larger despite number)
- Optocoupler default: Without SMD indicator (S1/S2), assume DIP-4
Series Extraction
- Phototransistor SMD normalization: PT19-21 extracts as "PT1921" (dash removed)
- RGB LED series: Uses the 3-digit format (19-337) not 2-digit
Replacement Logic
- Same series required:
isOfficialReplacement()requires matching series - Color matching for LEDs: If both parts have identifiable colors, they must match
- Optocouplers/sensors: Same series alone is sufficient for replacement
