Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete XRCWHT-L1-0000-00A02 is determined by the following critical parameters:

Mechanical Compatibility:

• Package / Case: 3529 (9073 Metric)
• Mounting Type: Surface Mount
• Size / Dimension: 0.354" L x 0.276" W (9.00mm x 7.00mm)
• Height - Seated (Max): 0.181" (4.60mm)

Optical & Electrical Compatibility:

• Color: White, Cool
• CCT (K): 6350K (primary match) or adjacent color temperatures (6000K, 5000K)
• Flux @ 25°C, 350mA: 91lm (87lm ~ 94lm)
• Current - Test: 350mA
• Viewing Angle: 90°
• CRI: 75 (Typ)

Regulatory & Environmental:

• RoHS Compliant
• REACH Unaffected
• Moisture Sensitivity Level (MSL): 4 (72 Hours)

All substitute parts are from the active XLamp® XR-E series, which maintains identical mechanical footprint, optical output, and regulatory compliance while offering improved electrical efficiency and higher maximum current rating.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Exact Match): XREWHT-L1-0000-00A02 and XREWHT-L1-R250-00A02 are direct functional equivalents, both maintaining 6350K color temperature. The difference between these two is packaging format: standard packaging versus Tape & Reel (TR). Both are active products with RoHS compliance and REACH unaffected status.

Secondary Substitutes (Color Temperature Variants): XREWHT-L1-0000-00A03 and XREWHT-L1-R250-00A03 (6000K) and XREWHT-L1-0000-00AE3 and XREWHT-L1-R250-00AE3 (5000K) are suitable where color temperature flexibility is acceptable. All maintain identical optical output (91lm), CRI (75), and mechanical compatibility.

Performance Improvements in XLamp® XR-E Series: All substitute parts offer improved thermal performance (8°C/W versus 12°C/W) and higher maximum current rating (1A versus 500mA), enabling enhanced design flexibility while maintaining backward compatibility at the 350mA test current.

Compliance & Supply: All substitute parts maintain RoHS compliance, REACH unaffected status, and MSL 4 (72 Hours) rating, ensuring regulatory continuity. Active product status guarantees long-term supply availability.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-00A02 directly replace XRCWHT-L1-0000-00A02 on existing PCBs? A: Yes. Both parts use identical 3529 (9073 Metric) package with matching footprint dimensions (0.354" L x 0.276" W, 4.60mm max height). No PCB redesign is required.

Q: What is the difference between XREWHT-L1-0000-00A02 and XREWHT-L1-R250-00A02? A: Both are electrically and optically identical. The difference is packaging format: XREWHT-L1-0000-00A02 is standard packaging, while XREWHT-L1-R250-00A02 is supplied in Tape & Reel (TR) format for automated assembly.

Q: Can I use XREWHT-L1-0000-00A03 (6000K) instead of XREWHT-L1-0000-00A02 (6350K)? A: Yes, if color temperature variation is acceptable for your application. Both maintain identical luminous flux (91lm), CRI (75), and electrical characteristics at 350mA test current. The 350K difference in CCT represents a minor shift toward neutral white.

Q: What is the impact of the 0.2V lower forward voltage in XLamp® XR-E parts? A: The XR-E series operates at 3.3V typical versus 4.6V for the XR-C. This 0.2V reduction improves power efficiency and reduces thermal load. Existing current-limiting circuits will function correctly; no recalculation is required for standard 350mA operation.

Q: Are all substitute parts RoHS compliant? A: Yes. All XLamp® XR-E substitute parts are RoHS compliant and REACH unaffected, maintaining regulatory equivalence with the original XRCWHT-L1-0000-00A02.

Q: What is the advantage of the improved thermal resistance (8°C/W vs 12°C/W)? A: Lower thermal resistance improves heat dissipation from the LED junction to the PCB, enabling higher current operation and better thermal stability. At standard 350mA operation, this provides design margin for thermal management.

Q: Can I use the higher 1A maximum current rating of XLamp® XR-E parts? A: The 1A maximum rating provides design flexibility for future applications. However, operation at 350mA test current maintains identical performance to the original part. Higher current operation requires thermal analysis and may alter optical and lifetime characteristics.
