Key Parameters

Substitute Part Grouping Explanation

Substitute parts are qualified based on the following criteria:

Mechanical Compatibility:

• Identical package type: 3529 (9073 Metric) surface mount
• Identical physical dimensions: 0.354" L x 0.276" W (9.00mm x 7.00mm)
• Identical seated height: 0.181" (4.60mm)
• Surface mount mounting type

Optical Compatibility:

• Identical color: White, Neutral
• Identical CCT: 4750K (for direct CCT-matched substitutes)
• Identical flux output: 91lm at 25°C, 350mA test current
• Identical viewing angle: 90°

Electrical Compatibility:

• Identical test current: 350mA
• Forward voltage tolerance: 3.3V to 4.6V range acceptable for circuit design
• Identical MSL rating: 4 (72 Hours)

Regulatory Compliance:

• RoHS Compliant status maintained
• REACH Unaffected status maintained
• Identical ECCN and HTSUS classifications

The XLamp® XR-E series substitutes (XREWHT base product number) are active production parts offering superior thermal performance (8°C/W vs. 12°C/W) and higher efficiency (79 lm/W vs. 74 lm/W) while maintaining full mechanical and optical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct CCT Match (4750K): XREWHT-L1-R250-00AA2 and XREWHT-L1-0000-00AA2 are primary substitutes for XRCWHT-L1-R250-00AA2. Both maintain identical color temperature, flux output, and mechanical compatibility. The XR-E series offers improved thermal performance (8°C/W vs. 12°C/W) and higher luminous efficacy (79 lm/W vs. 74 lm/W). Forward voltage difference (3.3V vs. 4.6V) is within acceptable design tolerance for most LED driver circuits.

Alternative CCT Options: XREWHT-L1-R250-00AA3 / XREWHT-L1-0000-00AA3 (4300K) and XREWHT-L1-R250-00AA4 / XREWHT-L1-0000-00AA4 (4000K) provide substitution for applications where CCT adjustment is acceptable. All maintain identical flux, current, viewing angle, and mechanical specifications.

Packaging Consideration: Tape & Reel (TR) packaging is standard for active production parts. Bulk packaging availability is limited to the obsolete XRCWHT-L1-R250-00AA2.

Compliance Status: All substitute parts maintain RoHS Compliance and REACH Unaffected status, ensuring regulatory continuity for existing designs.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-R250-00AA2 directly replace XRCWHT-L1-R250-00AA2 in existing designs?

A: Yes. Both parts share identical package (3529), dimensions (9.00mm x 7.00mm), flux output (91lm), test current (350mA), viewing angle (90°), and color temperature (4750K). Forward voltage differs by 0.2V (3.3V vs. 4.6V), which is within typical LED driver tolerance. The XR-E substitute offers superior thermal performance and efficiency.

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

A: Both are 4750K neutral white XLamp® XR-E LEDs with identical electrical and optical specifications. The difference is packaging format: R250 indicates Tape & Reel with 250-unit reels, while 0000 indicates standard Tape & Reel packaging. Electrical and thermal performance are identical.

Q: Can I use XREWHT-L1-R250-00AA4 (4000K) instead of XRCWHT-L1-R250-00AA2 (4750K)?

A: Mechanically and electrically, yes. Both share identical package, dimensions, flux, current, and thermal specifications. However, CCT differs by 750K. Use only if application design permits color temperature adjustment or if neutral white 4000K is acceptable for the end application.

Q: What is the thermal resistance improvement in XR-E substitutes?

A: XR-E series parts feature 8°C/W thermal resistance compared to 12°C/W in the XR-C series. This 33% improvement reduces junction temperature rise, extending LED lifespan and enabling higher current operation in thermally constrained designs.

Q: Are all substitute parts RoHS compliant?

A: Yes. XRCWHT-L1-R250-00AA2 and all listed XREWHT substitutes are RoHS Compliant and REACH Unaffected, maintaining regulatory compliance for EU and global markets.

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

A: All parts carry MSL 4 (72 Hours) rating. This indicates moisture sensitivity level requiring storage at ≤30% relative humidity and limiting floor life to 72 hours after moisture barrier bag opening. Proper handling per IPC-A-610 standards is required.
