Key Parameters

Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-009F5 is based on the following criteria:

Mandatory Matching Parameters:

• Color: White, Neutral
• CCT: 4300K
• Package / Case: 3529 (9073 Metric)
• Viewing Angle: 90°
• Mounting Type: Surface Mount
• Luminous Flux @ 25°C, 350mA: 84lm (81lm ~ 87lm)
• CRI: 75 (Typ)
• RoHS Compliance: RoHS Compliant

Allowable Variations:

• Forward Voltage (Vf): 3.3V to 4.6V (within typical operating range)
• Current - Max: 500mA to 700mA (higher maximum rating acceptable)
• Thermal Resistance: 8°C/W to 12°C/W (lower thermal resistance acceptable)
• Series: XLamp® XR-C to XLamp® XR-E (same product family)
• Product Status: Obsolete to Active (Active status preferred for availability)

All substitute parts listed are from CreeLED, Inc., maintaining manufacturer consistency and design compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Exact CCT Match): XREWHT-L1-0000-009F5 and XREWHT-L1-R250-009F5 are direct functional equivalents with 4300K CCT matching the original part. Both are Active status products, ensuring long-term availability. The XLamp® XR-E series provides improved thermal performance (8°C/W vs. 12°C/W) and higher maximum current rating (700mA vs. 500mA). Forward voltage reduction from 4.6V to 3.3V is within acceptable operating margins for neutral white LED applications.

Secondary Substitute (Adjacent CCT): XREWHT-L1-0000-009E5 and XREWHT-L1-R250-009E5 operate at 4000K CCT, a 300K shift toward cooler white. These parts maintain identical luminous flux, CRI, and mechanical compatibility. Selection of 4000K variants is appropriate when CCT tolerance permits or when cooler color temperature is acceptable for the application.

Packaging Consideration: All substitute parts are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. The original part packaging designation is not specified; verify reel compatibility with existing pick-and-place equipment.

Compliance: All substitute parts maintain RoHS compliance and REACH unaffected status, consistent with the original part's regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-009F5 directly replace XRCWHT-L1-0000-009F5 in existing designs? A: Yes. Both parts share identical CCT (4300K), luminous flux (84lm), viewing angle (90°), and 3529 package dimensions. The 0.2V forward voltage reduction (4.6V to 3.3V) is within normal operating tolerance for LED driver circuits. The improved thermal resistance (8°C/W) is beneficial for thermal management.

Q: What is the difference between XREWHT-L1-0000-009F5 and XREWHT-L1-R250-009F5? A: Both parts are electrically and optically identical. The designation difference (R250) indicates reel configuration or packaging variant. Verify reel specifications with your supplier for compatibility with assembly equipment.

Q: Can I use 4000K variants (XREWHT-L1-0000-009E5 or XREWHT-L1-R250-009E5) instead of 4300K? A: Yes, if your application permits a 300K color temperature shift toward cooler white. Luminous flux, CRI, and all mechanical parameters remain identical. Confirm color temperature tolerance in your design specifications before substitution.

Q: Why is the original part obsolete? A: The XRCWHT-L1-0000-009F5 (XLamp® XR-C series) has been superseded by the XLamp® XR-E series, which offers improved efficiency (73 lm/W vs. 69 lm/W), better thermal performance, and higher maximum current rating. CreeLED has transitioned production to the newer XR-E platform.

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's packaging format is not specified in available data. Confirm packaging compatibility with your assembly process requirements.

Q: What is the impact of lower forward voltage on circuit design? A: The 0.2V reduction (4.6V to 3.3V) decreases power dissipation in series resistors and improves overall circuit efficiency. LED driver circuits designed for 4.6V operation will function correctly at 3.3V with slightly reduced current limiting. No circuit redesign is required for standard applications.
