Key Parameters

Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-008E3 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Color and CCT: White, Cool 5000K
• Luminous Flux @ 25°C, 350mA: 77lm (74lm ~ 81lm range)
• Test Current: 350mA
• Viewing Angle: 90°
• Package / Case: 3529 (9073 Metric)
• Mounting Type: Surface Mount
• Physical Dimensions: 0.354" L x 0.276" W (9.00mm x 7.00mm)
• Height - Seated (Max): 0.181" (4.60mm)
• RoHS Compliance: Required

Allowable Variation Parameters:

• Forward Voltage (Typ): 3.3V to 4.6V (within circuit design tolerance)
• Lumens/Watt: 63 to 67 lm/W (efficiency variation acceptable)
• Thermal Resistance: 8°C/W to 12°C/W (thermal design dependent)
• Current - Max: 500mA to 1A (higher rating acceptable for same test current)
• CRI: 75 (Typ) or unspecified (color rendering acceptable)

All substitute parts are from CreeLED XLamp® XR-E series, which maintains identical optical output and package specifications while offering active product status.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (XREWHT-L1-0000-008A1, XREWHT-L1-0000-008E3, XREWHT-L1-R250-008E3) are functionally equivalent to the obsolete XRCWHT-L1-0000-008E3 based on the following criteria:

Optical and Electrical Equivalence: All substitutes maintain identical luminous flux (77lm at 350mA), color temperature (5000K), viewing angle (90°), and test current specifications. The forward voltage reduction from 4.6V to 3.3V is within typical circuit design tolerance and results in improved efficiency (67 lm/W vs. 63 lm/W).

Thermal Performance: Substitute parts feature improved thermal resistance (8°C/W vs. 12°C/W), providing superior thermal management in the same package footprint.

Compliance and Reliability: All parts maintain RoHS compliance, identical MSL rating (4, 72 Hours), and active product status from CreeLED, ensuring long-term availability and supply chain stability.

Packaging Consideration: The main part is supplied in bulk packaging, while all substitutes are supplied in Tape & Reel format, which is standard for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-008E3 directly replace XRCWHT-L1-0000-008E3 in existing designs?

A: Yes. Both parts deliver 77lm at 350mA in the identical 3529 package with 90° viewing angle. The 0.2V forward voltage difference (3.3V vs. 4.6V) is within standard circuit design tolerance and does not require PCB modifications.

Q: What is the difference between XREWHT-L1-0000-008A1 and XREWHT-L1-0000-008E3?

A: Both are XLamp® XR-E parts with identical optical output and package specifications. XREWHT-L1-0000-008E3 specifies CRI of 75 (Typ) and maximum current of 1A, while XREWHT-L1-0000-008A1 does not specify these parameters. For applications requiring defined CRI or higher current capability, XREWHT-L1-0000-008E3 is preferred.

Q: What does the "R250" designation in XREWHT-L1-R250-008E3 indicate?

A: The R250 designation indicates the reel size for Tape & Reel packaging. This part is functionally identical to XREWHT-L1-0000-008E3 and differs only in packaging format for high-volume automated assembly.

Q: Are there thermal design implications when substituting to the XR-E series?

A: The XR-E substitutes feature improved thermal resistance (8°C/W vs. 12°C/W), resulting in lower junction temperatures under identical operating conditions. This enhancement does not require thermal design changes and provides margin improvement.

Q: What is the impact of the forward voltage reduction on circuit design?

A: The reduction from 4.6V to 3.3V decreases power dissipation by approximately 5.7% at 350mA test current. Existing current-limiting resistor values remain valid; no circuit modifications are required.

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

A: No. The main part (XRCWHT-L1-0000-008E3) is supplied in bulk packaging, while all substitutes are supplied in Tape & Reel (TR) format. Tape & Reel is standard for automated PCB assembly and offers improved handling and traceability.

Q: Can these parts be used interchangeably in production?

A: Yes, all three substitute parts meet identical functional specifications for 5000K cool white LED operation at 350mA in the 3529 package. Selection among substitutes may be based on CRI specification requirement, maximum current rating, or packaging preference.
