Key Parameters

Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-002F7 is determined by the following critical parameters:

• Color and CCT Match: Warm white at 3200K (identical to main part)
• Package Compatibility: 3529 (9073 Metric) surface mount package (identical footprint and mounting)
• Viewing Angle: 90° (identical)
• CRI: 80 typical (identical)
• Test Current: 350mA nominal operation (identical)
• Compliance: RoHS compliant, MSL 4 rating (identical)

The substitute part XREWHT-L1-0000-004F7 meets all these criteria while representing an active product from the same manufacturer. Although it belongs to the XLamp® XR-E series rather than XR-C, it maintains electrical and mechanical compatibility within the specified parameters.

Parameter Comparison

Engineering Selection Recommendations

The XREWHT-L1-0000-004F7 is a direct substitute for the obsolete XRCWHT-L1-0000-002F7 based on the following factors:

• Product Status: The substitute is active, ensuring continued availability and supply chain stability.
• Compliance: Both parts maintain RoHS compliance and identical MSL ratings, satisfying regulatory requirements.
• Mechanical Compatibility: Identical package dimensions (3529 / 9073 Metric) and mounting type ensure drop-in replacement capability on existing PCB layouts.
• Electrical Compatibility: Both parts operate at 350mA test current with matching color temperature (3200K) and CRI (80). The substitute operates at a lower forward voltage (3.3V vs. 4.6V) and delivers higher luminous flux (54 lm vs. 43 lm) at the same test current, representing improved performance characteristics.
• Thermal Performance: The substitute exhibits superior thermal resistance (8°C/W vs. 12°C/W), enabling better heat dissipation in thermal-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can the XREWHT-L1-0000-004F7 be used as a direct replacement for the XRCWHT-L1-0000-002F7?

A: Yes. Both parts share identical package geometry (3529 / 9073 Metric), mounting type (surface mount), color temperature (3200K), CRI (80), and test current (350mA). The substitute is mechanically and electrically compatible for PCB-level replacement.

Q: What are the key differences between these two parts?

A: The substitute (XR-E series) delivers higher luminous flux (54 lm vs. 43 lm) and efficiency (47 lm/W vs. 35 lm/W) at identical test current. It operates at a lower forward voltage (3.3V vs. 4.6V) and has superior thermal resistance (8°C/W vs. 12°C/W). The substitute supports higher maximum current (700mA vs. 500mA).

Q: Are there any compliance or certification differences?

A: No. Both parts are RoHS compliant with identical MSL ratings (4, 72 Hours). Regulatory compliance is maintained across the substitution.

Q: Does the lower forward voltage of the substitute affect circuit design?

A: The 0.2V difference (4.6V to 3.3V) is within typical design margins for LED driver circuits. Existing current-limiting designs will continue to function; however, power dissipation will be slightly reduced due to the lower voltage drop.

Q: What is the impact of improved thermal resistance in the substitute?

A: The lower thermal resistance (8°C/W vs. 12°C/W) of the substitute allows more efficient heat transfer from the LED junction to the PCB. This results in lower junction temperatures under identical operating conditions, potentially extending component life and improving reliability in thermally constrained applications.

Q: Are there packaging format differences?

A: The main part is supplied in bulk packaging, while the substitute is available in Tape & Reel (TR) format. Both formats are compatible with standard assembly processes; TR format is standard for high-volume production.
