Handler Implementation Notes ### Package Code Extraction ```java // 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 ```java // Through-hole: WP + size code // WP7113ID -> WP7113 // WP3114SGC -> WP3114 // SMD: Prefix + size code // KP-2012CGCK -> KP-2012 // APTD3216SRCPRV -> APTD3216 // AA3528SURSK -> AA3528 ``` ### Color Extraction ```java // 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) <!-- Add new learnings above this line -->
