Key Parameters

Substitute Part Grouping Explanation

Substitution of XRCWHT-L1-0000-008A2 is based on the following critical parameters that must remain constant or compatible:

• Package / Case: 3529 (9073 Metric) — identical mechanical footprint and mounting interface
• Color & CCT: White, Neutral — all substitutes maintain 4000K to 4750K color temperature range
• Flux Output: 77lm (74lm ~ 81lm) @ 25°C, 350mA — all substitutes deliver equivalent luminous output
• Current - Test: 350mA — standard operating current maintained across all substitutes
• Viewing Angle: 90° — identical optical characteristics
• Mounting Type: Surface Mount — compatible with existing PCB assembly processes
• Compliance: RoHS Compliant, REACH Unaffected, MSL 4 — regulatory and environmental requirements met

The XLamp® XR-E series substitutes differ in forward voltage (3.3V vs. 4.6V) and thermal resistance (8°C/W vs. 12°C/W), representing improved performance characteristics. All substitutes are active products with confirmed inventory availability.

Parameter Comparison

Engineering Selection Recommendations

All XLamp® XR-E substitutes (XREWHT-L1 series) are active products with full RoHS compliance and REACH unaffected status, meeting current regulatory requirements. The primary selection criterion is color temperature (CCT) requirement:

• XREWHT-L1-0000-008A2 or XREWHT-L1-R250-008A2: Select for 4750K neutral white applications matching the original XRCWHT-L1-0000-008A2 specification
• XREWHT-L1-0000-008A3 or XREWHT-L1-R250-008A3: Select for 4300K neutral white applications
• XREWHT-L1-0000-008A4 or XREWHT-L1-R250-008A4: Select for 4000K neutral white applications

Packaging format selection (standard Tape & Reel vs. R250 variant) depends on assembly line equipment compatibility. All substitutes deliver identical luminous flux (77lm) and maintain the same 350mA test current and 90° viewing angle. The XR-E series offers improved efficiency (67 lm/W vs. 63 lm/W) and superior thermal performance (8°C/W vs. 12°C/W).

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-008A2 directly replace XRCWHT-L1-0000-008A2 in existing designs?

A: Yes. Both parts share identical package (3529), footprint (9.00mm x 7.00mm), height (4.60mm), color temperature (4750K), and luminous output (77lm @ 350mA). The forward voltage difference (3.3V vs. 4.6V) requires circuit verification to confirm driver compatibility, but the 200mV reduction typically improves efficiency without affecting optical performance.

Q: What is the difference between XREWHT-L1-0000-008A2 and XREWHT-L1-R250-008A2?

A: Both parts are electrically and optically identical. The difference is packaging format: standard Tape & Reel (0000) versus R250 variant (R250). Selection depends on your assembly equipment specifications. Verify your pick-and-place system compatibility before ordering.

Q: Why do the substitute parts have lower forward voltage (3.3V vs. 4.6V)?

A: The XLamp® XR-E series represents a newer generation with improved semiconductor design. The 200mV reduction in forward voltage is a characteristic of the improved die technology and does not affect optical output or color temperature. Circuit design must accommodate this voltage difference.

Q: Are all substitute parts RoHS compliant?

A: Yes. All XREWHT-L1 series parts are RoHS Compliant and REACH Unaffected, meeting current regulatory requirements for electronic components.

Q: What is the significance of the thermal resistance difference (8°C/W vs. 12°C/W)?

A: The XLamp® XR-E series (8°C/W) provides superior thermal performance compared to the obsolete XR-C series (12°C/W). This means the LED junction operates at a lower temperature under identical power dissipation, extending operational life and maintaining color stability.

Q: Can I mix different CCT variants (4000K, 4300K, 4750K) in the same application?

A: No. Color temperature must be consistent across all LEDs in a luminaire or display to maintain uniform color appearance. Select all parts from a single CCT specification based on your design requirement.

Q: What is the Moisture Sensitivity Level (MSL) 4 requirement?

A: MSL 4 indicates the component requires controlled humidity storage and handling. Parts must be stored in dry conditions and have a 72-hour floor life after opening the moisture barrier bag. Follow standard SMD component handling procedures.
