Key Parameters

Substitute Part Grouping Explanation

Substitute parts are qualified based on the following critical parameters that determine functional equivalence:

Mechanical Compatibility:

• Package / Case: 3529 (9073 Metric)
• Size / Dimension: 0.354" L x 0.276" W (9.00mm x 7.00mm)
• Height - Seated (Max): 0.181" (4.60mm)
• Mounting Type: Surface Mount
• Viewing Angle: 90°

Optical Compatibility:

• Color: White, Warm
• Flux @ 25°C, 350mA: 59lm (57lm ~ 62lm)
• CRI (Color Rendering Index): 80 (Typ)

Electrical Compatibility:

• Current - Test: 350mA
• Voltage - Forward (Vf) Typ: 3.3V to 4.6V (within acceptable operating range)
• Current - Max: 500mA or higher

Regulatory Compliance:

• RoHS Status: RoHS Compliant
• REACH Status: REACH Unaffected
• Moisture Sensitivity Level (MSL): 4 (72 Hours)

All substitute parts are from the CreeLED XLamp® XR-E series (active product status) and maintain identical mechanical footprint, optical output, and electrical test current specifications. Variations in color temperature (2700K, 2900K, 3000K) and forward voltage (3.3V vs 4.6V) are within acceptable substitution parameters for warm white LED applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Exact Match): XREWHT-L1-R250-005E7 is the direct equivalent for XRCWHT-L1-R250-005E7. Both parts operate at 3000K color temperature with identical optical output (59lm @ 350mA), mechanical footprint, and viewing angle. The XR-E variant offers improved thermal performance (8°C/W vs 12°C/W) and higher maximum current rating (700mA vs 500mA). This part maintains active product status with RoHS compliance and REACH unaffected certification.

Alternative Substitutes (Color Temperature Variants): XREWHT-L1-R250-005E8 (2700K) and XREWHT-L1-R250-005F8 (2900K) are functionally equivalent with identical electrical and mechanical specifications. Selection between 2700K, 2900K, and 3000K depends on application color temperature requirements. All three variants are active products with equivalent compliance certifications.

Tape & Reel Packaging Options: XREWHT-L1-0000-005E7, XREWHT-L1-0000-005E8, and XREWHT-L1-0000-005F8 provide identical electrical and optical performance in Tape & Reel packaging. These parts are suitable for high-volume production environments where reel packaging is preferred over cut tape.

Compliance Assurance: All substitute parts maintain RoHS compliance, REACH unaffected status, and MSL 4 (72 Hours) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-R250-005E7 directly replace XRCWHT-L1-R250-005E7 in existing designs?

A: Yes. Both parts share identical mechanical footprint (3529 package, 9.00mm x 7.00mm), optical output (59lm @ 350mA, 3000K, 90° viewing angle), and electrical test current (350mA). The forward voltage difference (3.3V vs 4.6V) is within acceptable operating range for warm white LED applications. The XR-E variant provides superior thermal performance and higher maximum current rating.

Q: What is the difference between 2700K, 2900K, and 3000K variants?

A: Color temperature (CCT) determines the perceived warmth of the light output. 2700K produces the warmest tone, 2900K is intermediate, and 3000K is slightly cooler. All three variants deliver identical luminous flux (59lm @ 350mA) and CRI (80 Typ). Selection depends on application color temperature specification.

Q: Are Cut Tape and Tape & Reel packaging electrically equivalent?

A: Yes. Packaging format (Cut Tape vs Tape & Reel) does not affect electrical, optical, or thermal performance. Selection is based on production volume and assembly equipment compatibility. Cut Tape is suitable for lower volumes; Tape & Reel is optimized for automated high-volume production.

Q: What is the impact of the 0.2V forward voltage difference between XR-C and XR-E?

A: The 0.2V difference (4.6V vs 3.3V) results in lower power dissipation with XR-E parts. For a 350mA test current, this represents approximately 70mW reduction in power consumption. Circuit designs with current-limiting resistors or constant-current drivers accommodate this variation without performance degradation.

Q: Why is thermal resistance lower in XR-E (8°C/W) compared to XR-C (12°C/W)?

A: Improved thermal resistance in the XR-E series reflects enhanced package design and die attachment. Lower thermal resistance improves heat dissipation efficiency, reducing junction temperature at equivalent power levels. This provides better reliability margin and supports higher maximum current ratings (700mA vs 500mA).

Q: Are all substitute parts RoHS compliant and REACH unaffected?

A: Yes. All listed substitute parts maintain RoHS compliance and REACH unaffected status, ensuring compatibility with regulatory requirements for electronics manufacturing and distribution.

Q: What is MSL 4 (72 Hours) and how does it affect handling?

A: Moisture Sensitivity Level 4 indicates the component requires controlled storage conditions. MSL 4 (72 Hours) means the part can be exposed to ambient conditions (23°C, 50% relative humidity) for up to 72 hours before soldering. Extended exposure requires dry-pack storage with desiccant. Standard manufacturing protocols accommodate this specification.
