Engineering Selection Recommendations
Primary Substitutes (Exact Flux Match): XREWHT-L1-0000-005B6, XREWHT-L1-0000-005B7, XREWHT-L1-0000-005B8, XREWHT-L1-0000-005B9, XREWHT-L1-R250-005B6, XREWHT-L1-R250-005B7, XREWHT-L1-R250-005B8, and XREWHT-L1-R250-005B9 all deliver 59 lm at 350mA test current, matching the original part's luminous flux specification. All are RoHS Compliant with MSL 4 rating. These parts are active products with robust inventory levels.
Secondary Substitute (Enhanced Performance): XREWHT-L1-0000-006E5 delivers 65 lm at 350mA, representing a 10% flux increase over the original specification. This part operates at 4000K color temperature (neutral white) with CRI 75 typical. It is suitable for applications where increased brightness is acceptable or beneficial. This part is also RoHS Compliant with MSL 4 rating and carries the highest inventory level (2132 Pcs).
Compliance & Certification: All substitute parts maintain RoHS Compliance and REACH Unaffected status consistent with the original part. All carry identical MSL 4 (72 Hours) moisture sensitivity classification. ECCN and HTSUS codes remain unchanged across the product family.
Thermal Consideration: XLamp® XR-E substitutes feature improved thermal resistance (8°C/W) compared to the original XLamp® XR-C (12°C/W), resulting in lower junction temperatures at equivalent power dissipation.
Frequently Asked Questions (FAQ)
Q: Can XREWHT-L1-0000-006E5 be used as a direct replacement for XRCWHT-L1-0000-005B2?
A: XREWHT-L1-0000-006E5 is mechanically and electrically compatible. It shares the same 3529 package, 90° viewing angle, and 350mA test current. The primary difference is higher luminous flux (65 lm vs. 59 lm) and specified color temperature of 4000K. Applications requiring exact flux matching should use XREWHT-L1-0000-005B6, 005B7, 005B8, or 005B9 instead.
Q: What is the difference between XREWHT-L1-0000-005B6/7/8/9 and XREWHT-L1-R250-005B6/7/8/9?
A: The primary difference is packaging format. Parts without "R250" designation are supplied in Tape & Reel (TR) format. Parts with "R250" designation also use Tape & Reel format. Both groups are mechanically and electrically identical. Maximum current specification is not provided for R250 variants in available data.
Q: Are there any forward voltage considerations when substituting?
A: The original part operates at 4.6V typical forward voltage. All XLamp® XR-E substitutes operate at 3.3V typical. This 0.2V reduction is within normal white LED operating range and does not require circuit redesign for standard current-limiting applications. Verify that your current-limiting circuit accommodates this voltage difference if operating near supply voltage limits.
Q: Do all substitute parts maintain the same thermal characteristics?
A: No. The original XRCWHT-L1-0000-005B2 has thermal resistance of 12°C/W. All XLamp® XR-E substitutes feature improved thermal resistance of 8°C/W. This improvement results in lower junction temperatures at equivalent power dissipation, which is beneficial for reliability and long-term performance.
Q: Is moisture sensitivity level identical across all parts?
A: Yes. The original part and all eight substitute parts carry MSL 4 (72 Hours) classification. Handling, storage, and reflow procedures remain unchanged.
Q: Which substitute offers the best inventory availability?
A: XREWHT-L1-0000-006E5 carries the highest inventory level at 2132 Pcs. If exact flux matching is required, XREWHT-L1-0000-005B7 offers strong availability at 989 Pcs.
