Key Parameters

Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-007A6 is based on the following critical parameters that must remain constant across all equivalent parts:

• Color: White, Warm
• Flux @ 25°C, 350mA: 71lm (67lm ~ 74lm)
• Test Current: 350mA
• Viewing Angle: 90°
• Package / Case: 3529 (9073 Metric)
• Mounting Type: Surface Mount
• Size / Dimension: 0.354" L x 0.276" W (9.00mm x 7.00mm)
• Height - Seated (Max): 0.181" (4.60mm)
• RoHS Status: RoHS Compliant
• Moisture Sensitivity Level (MSL): 4 (72 Hours)
• REACH Status: REACH Unaffected

The XLamp® XR-E series substitutes maintain identical mechanical compatibility, optical performance, and regulatory compliance. Variations in CCT (2700K, 2850K, 3000K, 3250K, 3500K) and packaging format (Tape & Reel) are available to support different application requirements while preserving core electrical and thermal characteristics.

Parameter Comparison

Engineering Selection Recommendations

All XLamp® XR-E substitutes listed maintain RoHS Compliance, REACH Unaffected status, and MSL 4 (72 Hours) rating, ensuring regulatory and environmental compliance equivalent to the original XRCWHT-L1-0000-007A6.

The XLamp® XR-E series offers active product status, providing long-term supply chain security and manufacturing continuity. These parts deliver improved thermal performance (8°C/W versus 12°C/W) and higher luminous efficacy (61 lm/W versus 58 lm/W) while maintaining identical optical output and mechanical form factor.

For applications requiring the exact 3500K color temperature of the original part, XREWHT-L1-0000-007A6 and XREWHT-L1-R250-007A6 are direct functional equivalents. Alternative CCT options (2700K, 2850K, 3000K, 3250K) are available within the same series for designs permitting color temperature flexibility.

Forward voltage reduction from 4.6V to 3.3V in XR-E variants requires circuit verification to confirm compatibility with existing current-limiting designs. Thermal resistance improvement enables higher power density applications or enhanced thermal management in space-constrained designs.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-007A6 directly replace XRCWHT-L1-0000-007A6 in existing designs?

A: Yes. Both parts share identical optical output (71lm at 350mA), viewing angle (90°), package dimensions (3529/9073 Metric), and regulatory compliance. The 0.2V forward voltage reduction (4.6V to 3.3V) must be verified in the circuit design to confirm current-limiting resistor or driver compatibility.

Q: What is the difference between XREWHT-L1-0000-007A6 and XREWHT-L1-R250-007A6?

A: Both parts are electrically and optically identical. The difference is packaging format: XREWHT-L1-0000-007A6 is supplied in Tape & Reel format, while XREWHT-L1-R250-007A6 is also Tape & Reel. Consult the specific part number suffix for exact packaging configuration and reel specifications.

Q: Can I substitute a 2700K part (XREWHT-L1-0000-007AA) for the 3500K original?

A: Mechanical and electrical compatibility is maintained across all CCT variants within the XLamp® XR-E series. However, color temperature change from 3500K to 2700K will alter the visual appearance of the light output. This substitution is valid only if the application permits color temperature variation.

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

A: Improved thermal resistance in the XR-E series reflects enhanced package design and die attachment. This provides better heat dissipation and enables higher power density operation. Existing designs will benefit from improved thermal performance without circuit modification.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed XLamp® XR-E substitutes maintain RoHS Compliance and REACH Unaffected status, matching the regulatory profile of the original XRCWHT-L1-0000-007A6.

Q: What inventory levels are available for these substitute parts?

A: Inventory availability varies by part number. XREWHT-L1-0000-007A8 (3000K) and XREWHT-L1-0000-007AA (2700K) show the highest stock levels (1066 and 1097 units respectively), while XREWHT-L1-R250-007A7 (3250K) shows 675 units. Consult current inventory for real-time availability.
