Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete XRCWHT-L1-0000-008A3 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Package / Case: 3529 (9073 Metric) — identical footprint and height
• Mounting Type: Surface Mount — same assembly process
• Color: White, Neutral — consistent color output
• Viewing Angle: 90° — identical optical characteristics
• Current - Test: 350mA — standard operating current
• Flux @ 25°C: 77lm (74lm ~ 81lm) — luminous output range
• Lumens/Watt: maintained at 67 lm/W for XR-E series
• RoHS Status: RoHS Compliant — regulatory alignment
• MSL: 4 (72 Hours) — identical moisture handling
• REACH Status: REACH Unaffected — compliance consistency

Allowable Variation Parameters:

• Voltage - Forward (Vf): 3.3V (XR-E) vs. 4.6V (XR-C) — within acceptable circuit design tolerance
• Thermal Resistance: 8°C/W (XR-E) vs. 12°C/W (XR-C) — improved thermal performance
• CCT (K): 4300K or 4000K — neutral white range options
• Series: XLamp® XR-E (active) replaces XLamp® XR-C (obsolete)

All substitute parts are from the active XLamp® XR-E series and maintain identical mechanical fit and electrical performance within standard design margins.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (4300K Match): XREWHT-L1-0000-008A3 and XREWHT-L1-R250-008A3 are direct functional equivalents for applications requiring 4300K color temperature. Both parts are active products with identical optical and thermal specifications. The forward voltage reduction from 4.6V to 3.3V results in improved power efficiency (67 lm/W vs. 63 lm/W) and reduced thermal resistance (8°C/W vs. 12°C/W), providing enhanced performance margins in existing circuit designs.

Alternative Substitute (4000K Option): XREWHT-L1-0000-008A4 and XREWHT-L1-R250-008A4 provide substitution for applications where 4000K color temperature is acceptable. These parts maintain identical luminous output, current rating, and mechanical compatibility while offering the same efficiency and thermal improvements as the 4300K variants.

Compliance & Regulatory: All substitute parts maintain RoHS Compliance, REACH Unaffected status, and MSL 4 (72 Hours) moisture sensitivity, ensuring regulatory and supply chain continuity. The transition from obsolete XLamp® XR-C to active XLamp® XR-E series ensures long-term component availability and manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-008A3 directly replace XRCWHT-L1-0000-008A3 without circuit modification?

A: Yes. Both parts operate at 350mA test current with identical 77lm luminous output and 90° viewing angle in the same 3529 package. The 0.2V forward voltage difference (3.3V vs. 4.6V) is within standard design tolerance for LED driver circuits and typically requires no modification.

Q: What is the difference between XREWHT-L1-0000-008A3 and XREWHT-L1-R250-008A3?

A: Both parts are electrically and optically identical. The designation difference (0000 vs. R250) reflects internal manufacturing or packaging variants. Selection between these parts depends on supplier availability and inventory status.

Q: Should I select 4300K or 4000K substitute parts?

A: Selection depends on application color temperature requirements. XREWHT-L1-0000-008A3 and XREWHT-L1-R250-008A3 maintain the original 4300K specification. XREWHT-L1-0000-008A4 and XREWHT-L1-R250-008A4 provide 4000K output. Both color temperatures are neutral white and maintain identical luminous output.

Q: Are there thermal performance differences between the main part and substitutes?

A: Yes. The XLamp® XR-E substitutes feature 8°C/W thermal resistance compared to 12°C/W for the obsolete XLamp® XR-C. This represents improved thermal performance and allows for higher ambient temperature operation or reduced thermal management requirements.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All substitute parts maintain MSL 4 (72 Hours) classification, identical to the main part. Storage and handling procedures remain unchanged.

Q: Is the 3529 package footprint identical across 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 (0.181", 4.60mm). PCB layout and assembly processes require no modification.
