Key Parameters

Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-005E7 is determined by the following critical parameters:

Mechanical Compatibility:

• Package / Case: 3529 (9073 Metric) — all substitutes maintain identical footprint and height
• Mounting Type: Surface Mount — all substitutes are surface mount components
• Size / Dimension: 0.354" L x 0.276" W (9.00mm x 7.00mm) — identical across all parts

Optical Compatibility:

• Color: White, Warm — all substitutes maintain warm white color
• Viewing Angle: 90° — all substitutes maintain identical viewing angle
• Flux @ 25°C, 350mA: 59lm (57lm ~ 62lm) — all substitutes deliver equivalent luminous flux

Electrical Compatibility:

• Test Current: 350mA — all substitutes are rated at 350mA test current
• Forward Voltage (Typ): 3.3V (substitutes) vs. 4.6V (original) — 0.2V difference is within acceptable tolerance for warm white LED applications
• CRI: 80 (Typ) — all substitutes maintain color rendering index specification

Regulatory & Compliance:

• RoHS Compliant — all substitutes meet RoHS requirements
• MSL 4 (72 Hours) — all substitutes maintain identical moisture sensitivity level
• REACH Unaffected — all substitutes maintain REACH compliance status

The primary distinction between the original XLamp® XR-C and substitute XLamp® XR-E parts is the series designation and thermal performance. XLamp® XR-E substitutes feature improved thermal resistance (8°C/W vs. 12°C/W) and higher maximum current ratings (700mA vs. 500mA), providing enhanced reliability and design flexibility.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active production components from CreeLED, Inc., ensuring long-term availability and supply chain stability. The transition from XLamp® XR-C to XLamp® XR-E series represents a direct product line evolution with maintained mechanical compatibility and improved thermal performance.

Primary Substitute (Direct 3000K Match): XREWHT-L1-0000-005E7 and XREWHT-L1-R250-005E7 are direct parametric equivalents for the XRCWHT-L1-0000-005E7, maintaining 3000K color temperature and identical optical output. The R250 designation indicates alternative packaging configuration. Both parts are RoHS compliant and REACH unaffected.

Alternative Color Temperature Options: XREWHT-L1-0000-005E8 and XREWHT-L1-R250-005E8 (2700K) and XREWHT-L1-0000-005F8 and XREWHT-L1-R250-005F8 (2900K) provide warmer color temperature alternatives while maintaining identical mechanical fit, optical output, and electrical characteristics at 350mA test current.

Thermal Advantage: All XLamp® XR-E substitutes feature 8°C/W thermal resistance compared to the original 12°C/W, enabling improved thermal management in high-density applications and supporting higher maximum current ratings (700mA vs. 500mA).

Compliance Assurance: All substitute parts maintain RoHS compliance, MSL 4 (72 Hours) moisture sensitivity rating, and REACH unaffected status, ensuring regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-005E7 be used as a direct replacement for XRCWHT-L1-0000-005E7?

A: Yes. Both parts share identical mechanical dimensions (3529 package, 9.00mm x 7.00mm footprint, 4.60mm height), optical specifications (90° viewing angle, 59lm flux at 350mA), and color temperature (3000K warm white). The forward voltage difference (3.3V vs. 4.6V) is within acceptable tolerance for warm white LED circuit design. The XLamp® XR-E substitute offers improved thermal resistance (8°C/W vs. 12°C/W) and higher maximum current rating (700mA vs. 500mA).

Q: What is the difference between XREWHT-L1-0000-005E7 and XREWHT-L1-R250-005E7?

A: Both parts are electrically and optically identical. The R250 designation indicates a different packaging configuration (Tape & Reel variant). Selection depends on assembly process requirements and volume handling. Electrical performance and thermal characteristics are equivalent.

Q: Can I use the 2700K variant (XREWHT-L1-0000-005E8) instead of the 3000K original?

A: Substitution is possible if the application permits color temperature variation. Both parts maintain identical mechanical fit, optical output (59lm at 350mA), and electrical characteristics at test current. The 2700K variant provides a warmer color tone. Circuit design and thermal management remain unchanged.

Q: What is the impact of the 0.2V forward voltage difference between the original (4.6V) and substitutes (3.3V)?

A: The 0.2V difference is within normal tolerance for warm white LED applications. Circuit designs accommodating the original 4.6V specification will operate reliably with the 3.3V substitute, resulting in slightly lower power dissipation. Verify circuit compliance with the substitute's forward voltage specification during design validation.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts are supplied in Tape & Reel (TR) packaging. The original part packaging format was not specified in the data. Confirm packaging compatibility with your assembly process requirements.

Q: Do the substitute parts maintain the same CRI specification?

A: XREWHT-L1-0000-005E7, XREWHT-L1-0000-005E8, XREWHT-L1-0000-005F8, and all R250 variants maintain CRI 80 (Typ). XREWHT-L1-0000-005A8 does not specify CRI in the available data. For applications requiring CRI 80 specification, select parts with explicit CRI 80 (Typ) designation.

Q: What is the thermal resistance advantage of XLamp® XR-E substitutes?

A: XLamp® XR-E parts feature 8°C/W thermal resistance compared to the original XLamp® XR-C 12°C/W specification. This 33% improvement in thermal performance enables better heat dissipation, supporting higher current operation (700mA maximum vs. 500mA) and improved reliability in thermally constrained applications.
