Mechanical Compatibility:

• Package type: 3529 (9073 Metric) surface mount
• Physical dimensions: 0.354" L × 0.276" W (9.00 mm × 7.00 mm)
• Maximum seated height: 0.181" (4.60 mm)
• Mounting type: Surface Mount

Electrical Compatibility:

• Color specification: White, Cool
• Color temperature range: 5000K – 10000K
• Viewing angle: 90°
• Test current: 350 mA
• Forward voltage range: Compatible with 3.3V to 4.6V typical operation

Regulatory & Environmental:

• RoHS Compliance: Required
• REACH Status: Unaffected
• Moisture Sensitivity Level: MSL 4 (72 Hours)

The XREWHT-L1-0000-00601 qualifies as a direct substitute based on identical mechanical packaging, matching color and CCT specifications, compatible electrical parameters at the 350 mA test current, and equivalent regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

The XREWHT-L1-0000-00601 is qualified as a direct substitute for the obsolete XRCWHT-L1-0000-00501 based on the following engineering criteria:

Mechanical Interchangeability: Both parts share identical 3529 (9073 Metric) surface mount packaging, physical dimensions (9.00 mm × 7.00 mm), and maximum seated height (4.60 mm). PCB footprints and assembly processes require no modification.

Electrical Compatibility: Both parts operate at 350 mA test current with matching cool white color temperature (5000K – 10000K) and identical 90° viewing angle. The substitute's 3.3V typical forward voltage is within acceptable operating range for circuits designed for the original 4.6V specification. The substitute's higher maximum current rating (1 A vs. 500 mA) provides additional design margin without compromising compatibility.

Regulatory Compliance: Both parts maintain RoHS Compliance, REACH Unaffected status, and identical MSL 4 (72 Hours) moisture sensitivity classification, ensuring equivalent handling, storage, and environmental compliance requirements.

Product Status: The substitute is Active in production, ensuring long-term availability and supply chain continuity compared to the Obsolete status of the original part.

Performance Enhancement: The substitute delivers measurable improvements in luminous flux (65 lm vs. 59 lm at 350 mA) and efficiency (56 lm/W vs. 48 lm/W), along with superior thermal resistance (8°C/W vs. 12°C/W), providing operational benefits without design modification.

Frequently Asked Questions (FAQ)

Q: Can the XREWHT-L1-0000-00601 be used as a direct replacement without PCB modifications?

A: Yes. Both parts use identical 3529 (9073 Metric) surface mount packaging with matching physical dimensions and footprints. No PCB layout changes are required.

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

A: The original XRCWHT-L1-0000-00501 operates at 4.6V typical, while the substitute XREWHT-L1-0000-00601 operates at 3.3V typical. Both are compatible with standard LED driver circuits designed for cool white LEDs in this package class. The 0.2V difference is within normal operating tolerance for most applications.

Q: Does the substitute provide better performance?

A: The XREWHT-L1-0000-00601 delivers higher luminous flux (65 lm vs. 59 lm at 350 mA test current), improved efficiency (56 lm/W vs. 48 lm/W), and better thermal characteristics (8°C/W vs. 12°C/W). These represent performance enhancements over the original part.

Q: Are the color specifications identical?

A: Yes. Both parts are specified as White, Cool with identical CCT range of 5000K – 10000K and CRI of 75 (Typ). Color performance is equivalent.

Q: What is the maximum current difference, and does it affect compatibility?

A: The original part supports 500 mA maximum current, while the substitute supports 1 A maximum current. This difference does not affect compatibility; the substitute simply provides additional current headroom for circuit design flexibility.

Q: Are moisture sensitivity and handling requirements the same?

A: Yes. Both parts are classified as MSL 4 (72 Hours), requiring identical moisture control, storage, and handling procedures during assembly and deployment.

Q: Is the substitute currently available?

A: Yes. The XREWHT-L1-0000-00601 is classified as Active in production status, ensuring reliable supply chain availability compared to the Obsolete original part.
