Key Parameters

Substitute Part Grouping Explanation

Substitution of XRCWHT-L1-0000-005F8 is determined by the following critical parameters:

Primary Substitution Criteria:

• Color temperature: 2900K warm white
• Flux output: 59lm at 350mA test current
• CRI: 80 (Typ)
• Package: 3529 (9073 Metric)
• Viewing angle: 90°
• Mounting type: Surface Mount
• Test current: 350mA
• Compliance: RoHS Compliant, REACH Unaffected

Acceptable Parameter Variations:

• Forward voltage: 3.3V to 4.6V (XR-E series operates at 3.3V vs. XR-C at 4.6V)
• Maximum current: 500mA to 700mA (higher rating in XR-E series)
• Thermal resistance: 8°C/W to 12°C/W (improved in XR-E series)
• Lumens/Watt: 48 to 51 lm/W (efficiency improvement in XR-E series)
• Packaging format: Bulk or Tape & Reel (TR)

All four substitute parts belong to the active XLamp® XR-E series and maintain identical optical, thermal, and mechanical compatibility with the obsolete XR-C part.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: XREWHT-L1-0000-005F8

This part is the direct functional equivalent for 2900K applications. It maintains identical color temperature, flux output, and CRI specifications. The XR-E series offers improved thermal performance (8°C/W vs. 12°C/W) and higher maximum current rating (700mA vs. 500mA), providing enhanced reliability and design margin. Product status is active with full supply availability.

Secondary Recommendation: XREWHT-L1-R250-005F8

Identical electrical and optical specifications to XREWHT-L1-0000-005F8, differentiated only by packaging format (Tape & Reel with 250-unit reel configuration). Select this variant for high-volume production environments requiring automated assembly.

Alternative for 2700K Applications: XREWHT-L1-0000-005E8 or XREWHT-L1-R250-005E8

These parts operate at 2700K color temperature instead of 2900K. Use only when design specifications explicitly permit 2700K warm white operation. All other electrical, optical, and mechanical parameters remain equivalent to the 2900K variants.

All substitute parts carry RoHS Compliant and REACH Unaffected certifications, maintaining regulatory compliance with the original part.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-005E8 (2700K) be used as a direct replacement for XRCWHT-L1-0000-005F8 (2900K)?

A: No. While both parts are mechanically and electrically compatible, they differ in color temperature. XREWHT-L1-0000-005E8 operates at 2700K versus the original 2900K. Use this part only if your application design permits 2700K warm white operation.

Q: What is the difference between XREWHT-L1-0000-005F8 and XREWHT-L1-R250-005F8?

A: Both parts are electrically and optically identical. The difference is packaging format: XREWHT-L1-0000-005F8 is supplied in bulk, while XREWHT-L1-R250-005F8 is supplied in Tape & Reel format with 250-unit reels. Select based on your assembly process requirements.

Q: Why does the XR-E series show lower thermal resistance (8°C/W) than the XR-C (12°C/W)?

A: Lower thermal resistance indicates improved heat dissipation performance. The XR-E series represents a newer generation with enhanced thermal design, providing better temperature management during operation.

Q: Are all substitute parts RoHS compliant?

A: Yes. All four substitute parts (XREWHT-L1-0000-005E8, XREWHT-L1-0000-005F8, XREWHT-L1-R250-005E8, XREWHT-L1-R250-005F8) are RoHS Compliant and REACH Unaffected, maintaining regulatory compliance with the original XRCWHT-L1-0000-005F8.

Q: Can I use a substitute part with higher maximum current rating (700mA vs. 500mA)?

A: Yes. The XR-E series maximum current rating of 700mA is higher than the original 500mA specification. This provides additional design margin and does not create compatibility issues. Operate the part at your original design current (350mA test current) for equivalent performance.

Q: What is the impact of the 0.2V forward voltage difference (3.3V vs. 4.6V)?

A: The XR-E series operates at 3.3V typical forward voltage versus the XR-C at 4.6V. This 0.2V difference is within normal LED manufacturing tolerance and requires circuit evaluation. For series-connected LED strings, recalculate total voltage drop. For current-regulated designs, this difference has minimal impact.

Q: Are the mechanical dimensions identical between all parts?

A: Yes. All parts use the 3529 (9073 Metric) package with identical dimensions: 0.354" L x 0.276" W (9.00mm x 7.00mm) and maximum seated height of 0.181" (4.60mm). PCB footprints and assembly processes remain unchanged.
