Handler Implementation Notes

Package Code Extraction

// Through-hole: Map size code to package name
// WP7113ID -> 7113 -> T-1-3/4 (5mm)
// WP3114SGC -> 3114 -> T-1 (3mm)

// SMD: Convert metric to imperial
// KP-2012CGCK -> 2012 -> 0805
// APTD3216SRCPRV -> 3216 -> 1206
// AA3528SURSK -> 3528 -> 1411 (PLCC)

Series Extraction

// Through-hole: WP + size code
// WP7113ID -> WP7113
// WP3114SGC -> WP3114

// SMD: Prefix + size code
// KP-2012CGCK -> KP-2012
// APTD3216SRCPRV -> APTD3216
// AA3528SURSK -> AA3528

Color Extraction

// Look for standard color code patterns
// *SRC*, *SURSK* = Red
// *SGC*, *CGC*, *GC* = Green
// *SBC*, *BC* = Blue
// *SEC*, *YGC* = Yellow
// *WC*, *SWC* = White
// *RGB* = RGB multi-color

Learnings & Edge Cases

• WP replaced L prefix - Old Kingbright LEDs used "L" prefix (L7113ID), new lead-free versions use "WP" (WP7113ID)
• KP with/without dash - Both KP-2012 and KP2012 formats exist; handler should match both
• APTD vs APT - Both are right-angle LEDs; APTD is a newer/different variant designation
• Metric sizes in MPN - Unlike most manufacturers, Kingbright uses metric sizes (2012 not 0805) in part numbers
• Color codes are substring-matched - Position varies; "SRCPRV" contains "SRC" for red
• PRV suffix - Indicates Pb-free/RoHS compliant (most modern parts have this)
• K suffix - Often indicates Kelvin color temperature variant for white LEDs
• SK suffix - Often appears on AA series as bin code identifier
• Same series = replaceable - LEDs from same series (e.g., WP7113) but different colors are considered replaceable (same footprint)
