Key Parameters

Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-005F6 is determined by the following critical parameters:

• Color Temperature Match: 3700K warm white specification must be maintained
• Optical Output: Luminous flux of 59 lm at 350 mA test current (57–62 lm acceptable range)
• Electrical Compatibility: Forward voltage and maximum current ratings must support existing circuit designs
• Package Compatibility: 3529 (9073 Metric) SMD package ensures mechanical and thermal fit
• Viewing Angle: 90° beam angle for consistent light distribution
• Compliance: RoHS compliance and MSL rating (4) for manufacturing processes

The XREWHT-L1-0000-005F6 meets all substitution criteria within these parameters.

Engineering Selection Recommendations

The XREWHT-L1-0000-005F6 is the direct substitute for the obsolete XRCWHT-L1-0000-005F6. Selection is based on the following factors:

• Active Product Status: The substitute part is currently in active production, ensuring long-term availability and supply chain continuity
• Identical Optical Performance: Both parts deliver 59 lm at 350 mA with matching 3700K color temperature and 75 CRI
• Mechanical Compatibility: Identical 3529 package dimensions and SMD mounting type enable direct board-level replacement
• Compliance Alignment: Both parts maintain RoHS compliance and identical MSL ratings, supporting existing manufacturing processes
• Improved Thermal Performance: The substitute exhibits lower thermal resistance (8°C/W vs. 12°C/W), providing enhanced thermal management
• Enhanced Current Capability: Maximum current rating of 700 mA (vs. 500 mA) provides design flexibility for future applications

Frequently Asked Questions (FAQ)

Q: Can the XREWHT-L1-0000-005F6 be used as a direct replacement for the XRCWHT-L1-0000-005F6?

A: Yes. Both parts share identical optical output (59 lm at 350 mA), color temperature (3700K), viewing angle (90°), and package dimensions (3529 SMD). The substitute is mechanically and optically compatible for direct board-level substitution.

Q: What is the difference in forward voltage between these parts?

A: The main part (XRCWHT) operates at 4.6V, while the substitute (XREWHT) operates at 3.3V. This 0.2V difference must be evaluated in circuit designs with tight voltage tolerances. Most LED driver circuits accommodate this variation within standard operating ranges.

Q: Are there any thermal considerations when switching to the substitute part?

A: The substitute part features improved thermal resistance (8°C/W vs. 12°C/W), resulting in lower junction temperatures under identical operating conditions. This enhancement supports higher reliability and extended operational life.

Q: Do both parts meet the same compliance and manufacturing standards?

A: Yes. Both parts are RoHS compliant, carry identical MSL ratings (4, 72 hours), and share the same REACH and ECCN classifications, ensuring compatibility with existing manufacturing and quality processes.

Q: What is the significance of the higher maximum current rating on the substitute part?

A: The substitute part supports 700 mA maximum current compared to 500 mA on the main part. This provides additional design margin and flexibility for future applications, though both parts are tested and specified at 350 mA.
