Key Parameters

Substitute Part Grouping Explanation

Substitute parts are grouped by correlated electrical and mechanical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Color: White, Neutral (maintained across all substitutes)
• Package / Case: 3529 (9073 Metric) (identical mechanical footprint)
• Viewing Angle: 90° (identical optical characteristics)
• Test Current: 350mA (standard operating point)
• Flux @ 25°C, 350mA: 91lm (87lm ~ 94lm) (identical luminous output)
• Mounting Type: Surface Mount (identical assembly compatibility)
• Size / Dimension: 0.354" L x 0.276" W (9.00mm x 7.00mm) (identical PCB footprint)
• Height - Seated (Max): 0.181" (4.60mm) (identical clearance requirements)
• RoHS Status: RoHS Compliant (maintained compliance)
• MSL Rating: 4 (72 Hours) (identical moisture handling)

Secondary Variation Parameters:

• CCT (K): Available in 4000K, 4300K, and 4750K options
• Forward Voltage (Vf): XR-E series operates at 3.3V (vs. 4.6V for XR-C)
• Lumens/Watt: XR-E series achieves 79 lm/W (vs. 74 lm/W for XR-C)
• Thermal Resistance: XR-E series 8°C/W (vs. 12°C/W for XR-C)
• Packaging Format: Available in Tape & Reel (TR) configuration
• Product Status: All XR-E substitutes are Active

Parameter Comparison

Engineering Selection Recommendations

All XLamp® XR-E substitutes maintain identical mechanical compatibility and optical performance with the obsolete XRCWHT-L1-0000-00AA2. Selection among substitute parts depends on correlated temperature and efficiency requirements:

For 4750K Color Temperature Requirement: XREWHT-L1-0000-00AA2 or XREWHT-L1-R250-00AA2 provide direct CCT matching. The R250 variant offers Tape & Reel packaging for automated assembly. Both deliver 79 lm/W efficiency and 8°C/W thermal resistance.

For Alternative Color Temperatures: XREWHT-L1-0000-00AA3 and XREWHT-L1-R250-00AA3 (4300K) or XREWHT-L1-0000-00AA4 and XREWHT-L1-R250-00AA4 (4000K) are available when warmer color points are acceptable. All maintain identical luminous output and thermal performance.

Packaging Consideration: Tape & Reel (TR) variants (R250 designation) are recommended for high-volume production requiring automated pick-and-place assembly. Bulk packaging is suitable for manual assembly or lower-volume applications.

Compliance and Supply: All substitute parts maintain RoHS compliance and MSL 4 rating. Active product status ensures continued manufacturing support and supply availability, eliminating obsolescence risk associated with the original XR-C part.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-00AA2 directly replace XRCWHT-L1-0000-00AA2 on existing PCBs?

A: Yes. Both parts share identical 3529 package dimensions (9.00mm x 7.00mm), height (4.60mm), and 90° viewing angle. PCB footprints and assembly clearances are fully compatible. Forward voltage differs by 0.2V (3.3V vs. 4.6V), requiring circuit verification for current-limiting designs.

Q: What is the difference between XREWHT-L1-0000-00AA2 and XREWHT-L1-R250-00AA2?

A: Both parts are electrically and optically identical. The R250 designation indicates Tape & Reel packaging format suitable for automated assembly equipment. The non-R250 variant uses bulk packaging. Select based on assembly process requirements.

Q: Why do XR-E substitutes show 79 lm/W efficiency versus 74 lm/W for the original XR-C?

A: The XR-E series represents a newer generation with improved die efficiency and thermal management (8°C/W vs. 12°C/W). This results in higher lumens-per-watt performance at identical test current and luminous output.

Q: Are all substitute parts RoHS compliant?

A: Yes. All XLamp® XR-E substitutes maintain RoHS compliance status identical to the original XRCWHT-L1-0000-00AA2.

Q: Can I use 4300K or 4000K substitutes if my design specifies 4750K?

A: CCT selection depends on application requirements. If 4750K is specified for color matching or lighting quality, use XREWHT-L1-0000-00AA2 or XREWHT-L1-R250-00AA2. Alternative CCT options are available only if design specifications permit warmer color points.

Q: What is the MSL rating and why does it matter?

A: MSL 4 (72 Hours) indicates moisture sensitivity level. Parts must be stored in dry conditions and used within 72 hours of moisture barrier bag opening. All substitutes share this rating with the original part.
