Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Package / Case: All substitutes must use 3529 (9073 Metric) surface mount package
• Mounting Type: Surface mount compatibility required
• Physical Dimensions: 0.354" L x 0.276" W (9.00mm x 7.00mm) footprint and 0.181" (4.60mm) maximum seated height
• Viewing Angle: 90° optical characteristic
• Current - Test: 350mA nominal operation
• Color / CCT: White, Neutral spectrum (4300K or 4000K acceptable within neutral white range)
• Flux Output: 71lm (67lm ~ 74lm) at 25°C, 350mA
• Lumens/Watt Efficiency: Minimum 61 lm/W
• Compliance: RoHS Compliant, MSL 4 (72 Hours)

The XLamp® XR-E series substitutes meet all mechanical and electrical compatibility criteria. Forward voltage variation (3.3V vs. 4.6V) is within acceptable design tolerance for LED circuit operation. The XR-E series offers improved thermal resistance (8°C/W vs. 12°C/W) and active product status.

Parameter Comparison

Engineering Selection Recommendations

All four XLamp® XR-E substitutes are active products with RoHS compliance and identical MSL ratings, providing long-term supply continuity compared to the obsolete XR-C main part.

For 4300K CCT requirement: Select XREWHT-L1-0000-007A3 or XREWHT-L1-R250-007A3. Both maintain the original 4300K color temperature specification. The difference between these two is packaging format: standard packaging versus Tape & Reel (TR) for automated assembly.

For 4000K CCT alternative: XREWHT-L1-0000-007A4 and XREWHT-L1-R250-007A4 provide 4000K neutral white, acceptable within the neutral white spectrum for applications where slight color temperature shift is permissible.

Forward voltage consideration: The 0.2V reduction (4.6V to 3.3V) in XR-E series requires circuit verification to confirm LED driver or current-limiting resistor compatibility. This is a minor variation within typical LED circuit design tolerance.

Thermal performance: XR-E series offers superior thermal resistance (8°C/W vs. 12°C/W), resulting in lower junction temperature operation and extended LED lifespan under identical current conditions.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-007A3 directly replace XRCWHT-L1-0000-007A3 without circuit modification?

A: Mechanical and optical compatibility is direct. The 0.2V forward voltage difference (4.6V to 3.3V) requires verification of the LED driver or current-limiting circuit. Most standard LED circuits accommodate this variation without modification, but circuit-specific validation is necessary.

Q: What is the difference between XREWHT-L1-0000-007A3 and XREWHT-L1-R250-007A3?

A: Both parts are electrically and mechanically identical. The difference is packaging format: XREWHT-L1-0000-007A3 is standard packaging, while XREWHT-L1-R250-007A3 is supplied in Tape & Reel (TR) format for automated pick-and-place assembly. Select based on assembly process requirements.

Q: Is the 4000K version (XREWHT-L1-0000-007A4) suitable as a substitute for the 4300K main part?

A: Both are neutral white LEDs within the acceptable range. The 300K color temperature difference may be perceptible in color-critical applications. Substitution is valid for general illumination where neutral white spectrum is specified without strict CCT tolerance.

Q: Why does the XR-E series have lower thermal resistance than the XR-C?

A: Thermal resistance (8°C/W vs. 12°C/W) reflects improved thermal design in the XR-E package. This is a performance advantage, resulting in cooler LED operation at identical current levels.

Q: Are all substitute parts RoHS compliant and MSL rated identically?

A: Yes. All substitute parts carry RoHS Compliant status and MSL 4 (72 Hours) rating, matching the main part's compliance profile.
