Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-003F5 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Color and CCT: White, Neutral 4300K (exact match required)
• Package / Case: 3529 (9073 Metric) surface mount (physical and electrical interface)
• Viewing Angle: 90° (optical performance specification)
• Mounting Type: Surface Mount (assembly compatibility)
• CRI: 75 (color rendering consistency)

Allowable Variation Parameters:

• Forward Voltage (Vf): 3.3V to 4.6V range (within typical LED tolerance and circuit design margins)
• Test Current: 350mA nominal (standard test condition)
• Maximum Current: 500mA to 700mA (higher ratings provide design flexibility)
• Flux Output: Variation acceptable within performance envelope
• Lumens/Watt: Higher efficiency acceptable (improved performance)
• Thermal Resistance: Lower values acceptable (improved thermal management)

The XREWHT-L1-0000-005F5 qualifies as a direct substitute based on matching all mandatory criteria while offering improved electrical and thermal characteristics.

Engineering Selection Recommendations

The XREWHT-L1-0000-005F5 is the qualified substitute for XRCWHT-L1-0000-003F5 based on the following engineering factors:

Product Status Alignment: The main part is obsolete while the substitute is active production, ensuring long-term supply availability and manufacturing support.

Regulatory Compliance: Both parts maintain identical RoHS compliance, MSL rating (4), and REACH status, satisfying regulatory requirements without modification to assembly or handling procedures.

Electrical Compatibility: The 0.2V reduction in forward voltage (4.6V to 3.3V) falls within standard LED tolerance ranges and typical circuit design margins. Existing current-limiting circuits designed for the main part will operate within specification with the substitute.

Performance Enhancement: The substitute delivers 20% higher luminous flux and 27.5% improved efficiency at the same test current, providing measurable performance gains without circuit redesign.

Thermal Improvement: The 33% reduction in thermal resistance (12°C/W to 8°C/W) enhances thermal management, reducing junction temperature under identical operating conditions.

Physical Compatibility: Identical package dimensions, mounting type, and height ensure direct mechanical and electrical interchangeability without PCB modification.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-005F5 be used as a direct replacement without circuit modification?

A: Yes. The substitute maintains identical package, mounting type, viewing angle, and color specification. The 0.2V lower forward voltage is within standard LED operating tolerance and will not require circuit redesign for typical current-limiting applications.

Q: What is the impact of the higher maximum current rating (700mA vs 500mA)?

A: The higher maximum current rating of the substitute provides additional design margin and does not affect operation at the standard 350mA test current. Existing circuits will operate identically.

Q: Are there any thermal management differences?

A: The substitute has superior thermal characteristics (8°C/W vs 12°C/W). This results in lower junction temperature under identical operating conditions, improving reliability and potentially extending operational life.

Q: Does the 20% higher flux output require any circuit adjustment?

A: No. The higher luminous flux is an inherent performance improvement of the newer XLamp® XR-E generation. Existing circuits will deliver proportionally brighter output without modification.

Q: Are packaging and handling procedures identical?

A: Yes. Both parts share identical MSL rating (4, 72 Hours), RoHS compliance, and REACH status. Existing procurement, storage, and assembly procedures apply without change.

Q: Is the substitute available in the same packaging format?

A: The substitute is supplied in Tape & Reel (TR) format. Confirm packaging requirements for your application; reel specifications may differ from the main part's original packaging.
