XRCWHT-L1-0000-009A3 Equivalent & Substitute Parts

Part Overview

The XRCWHT-L1-0000-009A3 is a CreeLED XLamp® XR-C neutral white LED (4300K) in 3529 surface mount package, rated for 350mA operation at 4.6V forward voltage. This part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The XLamp® XR-C series has been superseded by the XLamp® XR-E series, which maintains compatible electrical and mechanical specifications while offering improved thermal performance and active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of XRCWHT-L1-0000-009A3 is determined by the following critical parameters:

Electrical Compatibility:

• Color and CCT (4300K neutral white)
• Flux output at 25°C and 350mA test current (84lm nominal range)
• Test current rating (350mA)
• Viewing angle (90°)

Mechanical Compatibility:

• Package type (3529 / 9073 Metric)
• Physical dimensions (9.00mm x 7.00mm footprint, 4.60mm max height)
• Surface mount configuration

Regulatory & Environmental:

• RoHS compliance
• MSL rating (4)
• REACH status

The substitute parts are drawn from the XLamp® XR-E series, which maintains identical mechanical footprint, flux output, test current, and viewing angle specifications. Forward voltage differs slightly (3.3V vs. 4.6V), and thermal resistance improves (8°C/W vs. 12°C/W). All substitutes are active products with current manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts from the XLamp® XR-E series are qualified replacements for XRCWHT-L1-0000-009A3 based on electrical and mechanical compatibility. Selection between substitutes depends on correlated color temperature (CCT) requirements:

For 4300K CCT applications: XREWHT-L1-0000-009A3 or XREWHT-L1-R250-009A3 maintain the original color specification. Both are active products with identical electrical and mechanical parameters.

For 4000K CCT applications: XREWHT-L1-0000-009A4 or XREWHT-L1-R250-009A4 provide a cooler white tone while maintaining all other specifications.

All substitutes offer improved thermal performance (8°C/W vs. 12°C/W) and higher luminous efficacy (73 lm/W vs. 69 lm/W). Forward voltage is reduced from 4.6V to 3.3V, which may require minor circuit adjustments in current-limiting designs. All substitutes maintain RoHS compliance, MSL 4 rating, and REACH unaffected status, ensuring regulatory continuity.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-009A3 be used as a direct replacement for XRCWHT-L1-0000-009A3?

A: Yes. Both parts share identical flux output (84lm at 350mA), viewing angle (90°), package type (3529), physical dimensions (9.00mm x 7.00mm), and color temperature (4300K). The forward voltage difference (3.3V vs. 4.6V) is within typical circuit tolerance for LED applications using current-limiting designs.

Q: What is the difference between XREWHT-L1-0000-009A3 and XREWHT-L1-R250-009A3?

A: Both parts are electrically and mechanically identical. The difference is in packaging designation: "-0000-" indicates standard tape and reel packaging, while "-R250-" indicates an alternative reel configuration. Selection depends on assembly equipment compatibility and supply chain requirements.

Q: Why do the substitute parts have lower forward voltage (3.3V vs. 4.6V)?

A: The XLamp® XR-E series represents an improved generation of the XLamp® XR-C. The reduced forward voltage reflects improved semiconductor design while maintaining identical flux output and efficiency. Circuits using current-limiting resistors or constant-current drivers will accommodate this variation automatically.

Q: Are there CCT options available for substitution?

A: Yes. XREWHT-L1-0000-009A4 and XREWHT-L1-R250-009A4 provide 4000K (cooler white) as an alternative to the original 4300K specification. All other electrical and mechanical parameters remain identical.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All substitute parts are RoHS compliant, carry MSL 4 rating (72 hours), and maintain REACH unaffected status, matching the original part's regulatory profile.
