Key Parameters

Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-00703 is determined by the following critical parameters:

Mechanical Compatibility: Package type (3529/9073 Metric), physical dimensions (9.00mm x 7.00mm), and height (4.60mm max) must remain identical for PCB layout and assembly compatibility.

Electrical Compatibility: Forward voltage, test current (350mA), and maximum current ratings must support the existing circuit design. Flux output at the test current must remain within acceptable ranges for the application.

Optical Compatibility: Color temperature (6000K Cool White) and viewing angle (90°) define the functional performance requirements.

Regulatory Compliance: RoHS compliance and MSL rating must be maintained.

The two substitute parts listed below are from the XLamp® XR-E series, which shares identical mechanical packaging and optical specifications with the XR-C series while offering improved electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

XREWHT-L1-0000-00703 (Primary Substitute): This part is the direct equivalent for the XRCWHT-L1-0000-00703. It maintains identical color temperature (6000K), flux output (71lm at 350mA), viewing angle (90°), and mechanical packaging. The XLamp® XR-E series offers improved thermal resistance (8°C/W vs. 12°C/W) and extended maximum current rating (1A vs. 500mA). Forward voltage is 3.3V (vs. 4.6V), which represents a 0.2V reduction and may require circuit verification for constant-current driver compatibility. Product status is Active, ensuring long-term availability and supply chain stability.

XREWHT-L1-0000-007E3 (Secondary Substitute): This part is functionally equivalent with one exception: color temperature is 5000K (Neutral White) rather than 6000K (Cool White). All other parameters—flux output, viewing angle, mechanical packaging, thermal resistance, and maximum current—are identical to the primary substitute. This option is suitable only if the application can accommodate a shift from Cool White to Neutral White color temperature. Product status is Active.

Both substitutes are RoHS Compliant and carry identical MSL ratings (4, 72 Hours), maintaining regulatory compliance and moisture handling requirements.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-00703 be used as a direct replacement for XRCWHT-L1-0000-00703?

A: Yes. Both parts share identical mechanical packaging (3529/9073 Metric), optical specifications (6000K, 90° viewing angle), and flux output (71lm at 350mA test current). The forward voltage differs by 0.2V (3.3V vs. 4.6V), which must be verified against the circuit's constant-current driver specifications to ensure proper operation.

Q: What is the difference between the two substitute parts?

A: XREWHT-L1-0000-00703 maintains the original 6000K color temperature, while XREWHT-L1-0000-007E3 operates at 5000K. All other electrical and mechanical parameters are identical. Selection depends on whether the application requires Cool White (6000K) or can accept Neutral White (5000K) color temperature.

Q: Why does the thermal resistance differ between the main part and substitutes?

A: The XLamp® XR-E series (substitutes) features improved thermal design with 8°C/W thermal resistance compared to 12°C/W for the XLamp® XR-C series (main part). This represents a design improvement in the newer series and does not affect substitution compatibility.

Q: Are there any compliance or packaging differences?

A: No. All three parts are RoHS Compliant with identical MSL ratings (4, 72 Hours). The main part is supplied in standard packaging, while both substitutes are supplied in Tape & Reel (TR) format. This packaging difference does not affect electrical or mechanical compatibility.

Q: What is the impact of the maximum current rating increase from 500mA to 1A?

A: The XLamp® XR-E series supports higher maximum current (1A vs. 500mA), providing design flexibility for future applications. At the standard test current of 350mA, both parts operate identically. The increased maximum current rating does not affect substitution compatibility for existing designs.

Q: Is the 0.2V forward voltage difference significant?

A: The forward voltage difference (3.3V vs. 4.6V) must be evaluated against the circuit's constant-current driver design. If the driver is designed with sufficient headroom, this difference is not problematic. Verification with the circuit design is required before implementation.
