Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the XRCWHT-L1-0000-004F7 are selected from the active XLamp® XR-E series based on the following compatibility criteria:

Mechanical Compatibility:

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

Electrical Compatibility:

• Identical test current: 350mA
• Identical flux output @ 25°C, 350mA: 54 lm (52–57 lm range)
• Identical CRI: 80 (Typ)
• Identical viewing angle: 90°
• Forward voltage within acceptable range: 3.3V (XR-E series) vs. 4.6V (XR-C original)
• Higher maximum current rating in XR-E series (700mA vs. 500mA original)

Compliance & Status:

• All substitute parts are Active product status
• All substitute parts maintain RoHS Compliance
• All substitute parts maintain REACH Unaffected status
• All substitute parts use identical MSL rating: 4 (72 Hours)

Color Temperature Options: Substitutes are available across the warm white spectrum (2700K, 2900K, 3000K, 3200K), allowing selection based on application requirements while maintaining all other electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts from the XLamp® XR-E series are direct functional equivalents to the obsolete XRCWHT-L1-0000-004F7. Selection among substitutes is determined by color temperature requirement:

XREWHT-L1-0000-004F7 (3200K): Exact color temperature match to the original part. Recommended for applications where 3200K warm white output is specified.

XREWHT-L1-0000-004E7 (3000K): Suitable for applications tolerating 200K color temperature shift toward neutral white.

XREWHT-L1-0000-004F8 (2900K): Suitable for applications tolerating 300K color temperature shift toward deeper warm white.

XREWHT-L1-0000-004E8 (2700K): Suitable for applications tolerating 500K color temperature shift toward deepest warm white.

All substitute parts maintain identical electrical performance at the 350mA test current, identical mechanical fit in 3529 package footprints, and identical compliance certifications. The XR-E series offers improved thermal performance (8°C/W vs. 12°C/W) and higher maximum current rating (700mA vs. 500mA), providing enhanced operational margin. All parts are Active status with full supply availability.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-004F7 be used as a direct replacement for XRCWHT-L1-0000-004F7?

A: Yes. Both parts share identical color temperature (3200K), identical flux output (54 lm @ 350mA), identical package dimensions (3529 / 9.00 mm × 7.00 mm), and identical viewing angle (90°). The forward voltage difference (3.3V vs. 4.6V) is within acceptable design margin for most applications. The XR-E substitute offers improved thermal performance and higher current rating.

Q: What is the impact of the 0.2V forward voltage difference between the original and substitute parts?

A: The XREWHT series operates at 3.3V typical versus the original 4.6V typical. This 0.2V reduction results in lower power dissipation and improved efficiency. For series-connected LED strings, the voltage difference must be accounted for in current-limiting circuit design. For individual LED applications with current regulation, the voltage difference has minimal impact on performance.

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

A: All substitute parts are supplied in Tape & Reel (TR) format. The original XRCWHT-L1-0000-004F7 packaging format is not specified in the provided data. Confirm packaging compatibility with your procurement requirements.

Q: Can I substitute a 2700K part (XREWHT-L1-0000-004E8) for the 3200K original?

A: Electrical and mechanical compatibility is confirmed. The 500K color temperature shift (3200K to 2700K) represents a perceptible change in light appearance, shifting from warm white toward deeper warm white. This substitution is valid only if the application tolerates this color temperature change.

Q: What is the significance of the improved thermal resistance in the XR-E series?

A: The XR-E series thermal resistance is 8°C/W compared to 12°C/W in the original XR-C series. This 33% improvement in thermal performance allows for better heat dissipation at equivalent power levels, enabling higher operational reliability and extended component life in thermally constrained applications.

Q: Are all substitute parts RoHS and REACH compliant?

A: Yes. All substitute parts maintain RoHS Compliance and REACH Unaffected status, identical to the original part. All parts carry MSL rating 4 (72 Hours), requiring identical moisture control during storage and handling.
