Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete XRCWHT-L1-0000-00702 is determined by the following critical parameters:

Mechanical Compatibility:

• Identical package type: 3529 (9073 Metric)
• Identical footprint dimensions: 0.354" L x 0.276" W (9.00mm x 7.00mm)
• Identical maximum seated height: 0.181" (4.60mm)
• Surface mount mounting type

Optical Compatibility:

• Cool white color category maintained
• Identical viewing angle: 90°
• Identical flux output @ 25°C, 350mA test current: 71lm (67lm ~ 74lm range)
• Identical CRI: 75 (Typ)

Electrical Compatibility:

• Test current: 350mA (identical)
• Forward voltage tolerance: 3.3V to 4.6V acceptable range
• Maximum current rating: ≥500mA

Compliance & Environmental:

• RoHS Compliant status maintained
• MSL Rating 4 (72 Hours) maintained
• REACH Unaffected status maintained

All three substitute parts (XREWHT-L1-0000-00702, XREWHT-L1-0000-00703, XREWHT-L1-0000-007E3) meet these criteria. The primary difference among substitutes is correlated color temperature (CCT) variation within the cool white spectrum.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: XREWHT-L1-0000-00702

This part provides the closest match to the original XRCWHT-L1-0000-00702. It maintains identical CCT (6350K), identical optical flux output, and identical test current specifications. The XLamp® XR-E series is active and in production, ensuring long-term availability. The forward voltage is 0.2V lower (3.3V vs 4.6V), which is within acceptable tolerance for most circuit designs. The improved thermal resistance (8°C/W vs 12°C/W) and higher maximum current rating (1A vs 500mA) provide enhanced performance margins. RoHS compliance and MSL rating are maintained.

Secondary Substitutes: XREWHT-L1-0000-00703 and XREWHT-L1-0000-007E3

These parts are suitable when CCT variation is acceptable within the cool white spectrum. XREWHT-L1-0000-00703 operates at 6000K (350K lower than original), and XREWHT-L1-0000-007E3 operates at 5000K (1350K lower than original). Both maintain identical flux output, test current, CRI, and mechanical compatibility. Selection between these options depends on application-specific color temperature requirements. All three XLamp® XR-E substitutes are active products with superior thermal and current handling characteristics compared to the obsolete XR-C series.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-00702 be used as a direct replacement for XRCWHT-L1-0000-00702?

A: Yes. Both parts share identical package dimensions (3529 metric), footprint (9.00mm x 7.00mm), seated height (4.60mm), optical flux (71lm @ 350mA), CCT (6350K), CRI (75), and viewing angle (90°). The forward voltage difference (3.3V vs 4.6V) is within normal design tolerance. The XR-E substitute offers improved thermal resistance and higher maximum current rating.

Q: What is the difference between the three substitute parts?

A: All three substitutes are mechanically and electrically identical. The primary difference is correlated color temperature: XREWHT-L1-0000-00702 matches the original at 6350K, XREWHT-L1-0000-00703 is 6000K, and XREWHT-L1-0000-007E3 is 5000K. All maintain 71lm flux output and 75 CRI. Selection depends on whether the application requires exact CCT matching or can tolerate cool white variation.

Q: Are all substitute parts in active production?

A: Yes. All three XREWHT substitutes are classified as Active products from the XLamp® XR-E series, ensuring ongoing availability and supply chain stability compared to the obsolete XRCWHT original.

Q: What are the packaging differences?

A: The original XRCWHT-L1-0000-00702 packaging is listed as "-" (unspecified). All three XLamp® XR-E substitutes are supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly.

Q: Is the forward voltage difference significant?

A: The substitute parts operate at 3.3V typical forward voltage compared to 4.6V for the original. This 0.2V difference is within standard LED tolerance and acceptable for most circuit designs. Verify that your current-limiting circuit can accommodate this variation.

Q: Do the substitute parts maintain compliance certifications?

A: Yes. All substitute parts maintain RoHS Compliance, MSL Rating 4 (72 Hours), and REACH Unaffected status identical to the original part.

Q: What is the thermal resistance improvement?

A: The XLamp® XR-E substitutes feature 8°C/W thermal resistance compared to 12°C/W for the original XR-C part. This 33% improvement in thermal performance allows for better heat dissipation and more stable operation under sustained current conditions.
