XRCWHT-L1-0000-007E5 Equivalent & Substitute Parts

Part Overview

The XRCWHT-L1-0000-007E5 is a CreeLED XLamp® XR-C neutral white LED (4000K) in 3529 SMD package, rated for 350mA operation at 4.6V forward voltage with 71lm luminous flux at 25°C. 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 The XLamp® XR-C series has been superseded by the XLamp® XR-E series, which offers improved thermal characteristics and higher maximum current ratings while maintaining compatible package dimensions and optical performance.

Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-007E5 is determined by the following critical parameters:

• Color and CCT: All substitutes must be neutral white 4000K to maintain color consistency in lighting applications
• Luminous Flux: Substitutes must deliver 71lm (67lm ~ 74lm) at 350mA test current to ensure equivalent brightness
• Package Compatibility: All substitutes use the 3529 (9073 Metric) SMD package with identical footprint and height specifications
• Viewing Angle: 90° viewing angle must be maintained for optical performance equivalence
• Compliance: RoHS compliance and MSL 4 rating are required for manufacturing and storage compatibility

The three substitute parts listed below are all from the XLamp® XR-E series, which represents the active product line replacement for the obsolete XR-C series. These parts meet all critical substitution criteria while offering improved thermal performance.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are from the active XLamp® XR-E product line and are suitable replacements for the obsolete XRCWHT-L1-0000-007E5. Selection among the three XR-E variants should be based on the following factors:

XREWHT-L1-0000-007A4: This part is the baseline XR-E equivalent. It maintains identical luminous flux and test current specifications. The forward voltage is reduced to 3.3V (compared to 4.6V in the main part), resulting in improved efficiency at 61 lm/W. Maximum current rating is not specified for this variant. This part is suitable for applications where CRI specification is not critical.

XREWHT-L1-0000-007E5: This variant includes a specified CRI of 75 (Typ), matching the main part's color rendering performance. Maximum current rating is 700mA, providing higher operational headroom. This part is recommended for applications requiring documented color rendering index performance.

XREWHT-L1-R250-007E5: This part is functionally identical to XREWHT-L1-0000-007E5, with the same CRI specification and 700mA maximum current rating. The designation difference (R250 vs. 0000) indicates a different tape reel configuration. Selection between these two should be based on tape reel specifications required by assembly equipment.

All substitutes offer improved thermal resistance (8°C/W versus 12°C/W), enhanced efficiency, and active product status. RoHS compliance and MSL 4 rating are maintained across all options.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-007E5 be used as a direct drop-in replacement for XRCWHT-L1-0000-007E5?

A: Yes. Both parts share identical package dimensions (3529 SMD), footprint, height, viewing angle, and luminous flux specifications at the 350mA test current. The 0.2V reduction in forward voltage (4.6V to 3.3V) is within typical circuit design tolerances for LED applications and does not prevent direct substitution in most designs.

Q: What is the difference between XREWHT-L1-0000-007E5 and XREWHT-L1-R250-007E5?

A: These parts are electrically and optically identical. The designation difference indicates different tape reel configurations. Selection should be based on the specific tape reel format required by your assembly equipment. Both are active products with equivalent availability.

Q: Why does XREWHT-L1-0000-007A4 not specify a maximum current rating?

A: The maximum current specification is not provided in the available data for this part variant. For applications requiring operation above 350mA, XREWHT-L1-0000-007E5 or XREWHT-L1-R250-007E5 are recommended, as both specify 700mA maximum current.

Q: Is CRI specification important for my application?

A: CRI (Color Rendering Index) of 75 indicates the accuracy of color representation under the LED's light. If your application requires consistent color rendering performance, select XREWHT-L1-0000-007E5 or XREWHT-L1-R250-007E5, both of which specify CRI 75 (Typ). XREWHT-L1-0000-007A4 does not provide a CRI specification.

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

A: The XR-E substitutes offer 8°C/W thermal resistance compared to 12°C/W in the original XR-C part. Lower thermal resistance improves heat dissipation from the LED junction, resulting in lower operating temperatures and potentially extended component life under sustained operation.

Q: Are all substitutes available in the same packaging format?

A: The main part (XRCWHT-L1-0000-007E5) is supplied in bulk packaging. All three XR-E substitutes are supplied in Tape & Reel (TR) format. Verify that your assembly process is compatible with tape and reel packaging before selection.

Q: What compliance certifications apply to these parts?

A: All parts listed are RoHS Compliant, REACH Unaffected, and carry MSL 4 (72 Hours) moisture sensitivity rating. ECCN classification is EAR99 and HTSUS code is 8541.41.0000 for all variants.
