Key Parameters

Substitute Part Grouping Explanation

The XREWHT-L1-0000-005A7 qualifies as a direct substitute based on the following alignment criteria:

• Color Temperature Match: Both parts deliver 3250K warm white output, ensuring identical color rendering in end applications
• Package Compatibility: Identical 3529 (9073 Metric) surface mount package enables direct PCB footprint compatibility
• Viewing Angle Alignment: Both parts specify 90° viewing angle, maintaining optical performance characteristics
• Test Current Compatibility: Both parts are rated at 350mA nominal test current, allowing circuit design continuity
• Compliance Equivalence: Both parts maintain RoHS compliance and MSL 4 moisture sensitivity rating
• Thermal Package: Both utilize identical thermal resistance package specifications (12°C/W for XR-C; 8°C/W for XR-E)

The primary distinction lies in the XR-E series offering improved luminous efficiency and higher maximum current rating, representing a performance upgrade path from the obsolete XR-C generation.

Parameter Comparison

Engineering Selection Recommendations

The XREWHT-L1-0000-005A7 is the designated substitute for the obsolete XRCWHT-L1-0000-002A7. Selection is supported by:

• Active Product Status: The XR-E variant maintains current manufacturing and supply chain availability, eliminating obsolescence risk
• Regulatory Compliance: Both parts maintain identical RoHS and REACH compliance posture, ensuring regulatory continuity
• Mechanical Interchangeability: Identical package dimensions and mounting specifications enable direct PCB layout reuse without redesign
• Thermal Performance Enhancement: The XR-E series provides improved thermal resistance (8°C/W vs. 12°C/W), reducing junction temperature in equivalent operating conditions
• Performance Improvement: The XR-E delivers 37% higher luminous flux (59lm vs. 43lm) and 46% improved efficiency (51 lm/W vs. 35 lm/W) at identical test current

Circuit designs operating the XR-C at 350mA will experience direct functional compatibility with the XR-E. Designs utilizing the full 500mA capability of the XR-C may operate the XR-E at higher current levels (up to 700mA maximum) for enhanced output if thermal management permits.

Frequently Asked Questions (FAQ)

Q: Can the XREWHT-L1-0000-005A7 be used as a direct replacement on existing PCBs designed for XRCWHT-L1-0000-002A7?

A: Yes. Both parts utilize identical 3529 surface mount package dimensions (9.00mm x 7.00mm) and seated height (4.60mm maximum). PCB footprints, solder pad layouts, and mechanical clearances require no modification.

Q: What are the electrical compatibility considerations?

A: The XR-E forward voltage is 0.2V lower (3.3V vs. 4.6V typical). Circuits designed with current-limiting resistors for the XR-C will deliver slightly higher current to the XR-E at identical supply voltage. For 350mA test current operation, this difference is within normal design tolerance. Verify current-limiting circuit design if operating near maximum current ratings.

Q: Are there thermal management differences?

A: The XR-E provides superior thermal performance with 8°C/W package resistance compared to 12°C/W for the XR-C. This represents a 33% improvement in thermal efficiency, resulting in lower junction temperatures under identical power dissipation conditions.

Q: Do both parts share identical color temperature output?

A: Yes. Both parts are specified at 3250K warm white color temperature, ensuring identical color rendering and chromaticity in end applications.

Q: What is the packaging difference between these parts?

A: The XRCWHT-L1-0000-002A7 is supplied in standard packaging, while the XREWHT-L1-0000-005A7 is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes and does not affect component performance or compatibility.

Q: Are moisture sensitivity and compliance ratings identical?

A: Yes. Both parts maintain MSL 4 (72 Hours) moisture sensitivity rating, RoHS compliance, and REACH unaffected status. Storage and handling requirements are equivalent.
