Cree LED MPN encoding patterns, suffix decoding, and handler guidance. Use when working with high-power LEDs, XLamp series, and SiC power devices.
Cree, Inc. (now Wolfspeed for SiC/power and branded as Cree LED after the 2021 spin-off) is known for:
Note: Cree LED was acquired by SMART Global Holdings in 2021 and continues to operate as Cree LED. The Wolfspeed brand focuses on SiC power devices.
Cree LED MPNs follow this general structure:
CLV[SERIES][VARIANT]-[COLOR][BIN]
│ │ │ │ │
│ │ │ │ └── Bin code (brightness/color bin): A, B, C, etc.
│ │ │ └── Color code: FK=warm white, WK=cool white
│ │ └── Variant letter: A, B, etc.
│ └── Series number: 1, 2, 6, etc.
└── CLV = Cree LED Vertical series
<!-- Add new learnings above this line -->CLVBA-[COLOR][BIN]
│ │ │
│ │ └── Bin code: A, B, C (brightness bin within color)
│ └── Color family: FK=warm white, WK=cool white
└── CLVBA = Cree LED Vertical Bin-coded A series
CLV1A-FKA
│ ││ │ │
│ ││ │ └── A = Brightness bin code
│ ││ └── FK = Warm white (typically 2700-3000K)
│ │└── A = Variant A
│ └── 1 = Series 1 (size/power category)
└── CLV = Cree LED Vertical
CLVBA-FKB
│ │ │
│ │ └── B = Brightness bin B (slightly different from A)
│ └── FK = Warm white color family
└── CLVBA = Cree LED Vertical Bin-coded A series
CLV6A-WKA
│ ││ │ │
│ ││ │ └── A = Brightness bin
│ ││ └── WK = Cool white (typically 5000-6500K)
│ │└── A = Variant A
│ └── 6 = Series 6 (larger/higher power)
└── CLV = Cree LED Vertical
| Prefix | Type | Description |
|---|---|---|
| CLV | High-power LED | Vertical structure LED, general lighting |
| CLVBA | Bin-coded LED | Specific brightness/color bin coding |
| XLamp | XLamp series | Professional lighting LEDs (XP, XM, XHP series) |
| Code | Color Temperature | Description |
|---|---|---|
| FK | 2700K-3000K | Warm white, residential lighting |
| WK | 5000K-6500K | Cool white, commercial/daylight |
Note: The current CreeHandler only implements CLV and CLVBA series. XLamp series (XP-E, XM-L, XHP) patterns are not yet registered.
| Suffix | Meaning |
|---|---|
| A | Standard brightness bin |
| B | Slightly different brightness (within tolerance) |
| C | Another brightness bin |
LEDs with the same series but different bin codes (e.g., CLVBA-FKA vs CLVBA-FKB) are considered interchangeable/replacements as they have the same color temperature and similar brightness.
// For CLVBA series, returns "SMD" (Surface Mount Device)
// CLVBA-FKA -> "SMD"
// CLVBA-WKB -> "SMD"
// For other CLV series, returns empty string
// CLV1A-FKA -> ""
Current Limitation: Package code extraction only handles CLVBA series. Other series return empty string.
// For CLVBA series: returns everything except last character (bin code)
// CLVBA-FKA -> "CLVBA-FK"
// CLVBA-WKB -> "CLVBA-WK"
// For other CLV series: returns part before dash
// CLV1A-FKA -> "CLV1A"
// CLV2B-WKA -> "CLV2B"
// LEDs with same series are considered official replacements
// (same footprint, similar brightness, same color)
isOfficialReplacement("CLVBA-FKA", "CLVBA-FKB") -> true // Same series (CLVBA-FK)
isOfficialReplacement("CLVBA-FKA", "CLVBA-WKA") -> false // Different series (FK vs WK)
