Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the XRCWHT-L1-0000-006E4 is determined by the following critical parameters:

Mechanical Compatibility:

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

Electrical Compatibility:

• Color: White, Neutral
• Flux output @ 25°C, 350mA test current: 65lm (62lm ~ 67lm)
• Test current: 350mA
• CRI: 75 (Typ)
• Viewing angle: 90°

Compliance & Certification:

• RoHS Compliant
• MSL 4 (72 Hours)
• REACH Unaffected
• ECCN: EAR99

The substitute parts listed below meet all mechanical and electrical compatibility requirements. Variations in forward voltage (Vf), maximum current rating, thermal resistance, and correlated color temperature (CCT) within the neutral white spectrum are permitted where the primary electrical output (flux) and test current specifications remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (XREWHT-L1-0000-006E4, XREWHT-L1-0000-006E5, XREWHT-L1-0000-006F5) are classified as active products with current manufacturing status, providing supply chain continuity for the obsolete XRCWHT-L1-0000-006E4.

Primary Substitute: XREWHT-L1-0000-006E4

This part maintains the closest CCT specification (4500K) to the original part. It provides identical flux output (65lm at 350mA) and CRI (75 Typ) while offering improved thermal performance (8°C/W versus 12°C/W) and higher maximum current rating (700mA versus 500mA). Forward voltage is reduced from 4.6V to 3.3V, which may require circuit verification in voltage-sensitive applications.

Secondary Substitutes: XREWHT-L1-0000-006E5 and XREWHT-L1-0000-006F5

These parts provide equivalent electrical performance with CCT variations (4000K and 4300K respectively). Selection between these options depends on application-specific color temperature requirements. Both maintain identical flux output, CRI, and mechanical compatibility.

All substitute parts comply with RoHS, REACH, and MSL 4 specifications, ensuring regulatory and environmental compatibility with the original part.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-006E4 be used as a direct replacement for XRCWHT-L1-0000-006E4?

A: Yes. Both parts share identical mechanical dimensions (3529 package, 9.00mm x 7.00mm x 4.60mm max height), identical flux output (65lm at 350mA), identical CRI (75 Typ), and identical viewing angle (90°). The forward voltage differs by 0.2V (4.6V to 3.3V), which must be verified in circuit design to ensure proper current limiting and voltage regulation.

Q: What is the difference between the three substitute parts?

A: The primary difference is correlated color temperature (CCT): XREWHT-L1-0000-006E4 is 4500K (closest to original), XREWHT-L1-0000-006F5 is 4300K, and XREWHT-L1-0000-006E5 is 4000K. All three maintain identical flux output, CRI, and electrical test current specifications. Selection depends on application color temperature requirements.

Q: Are there packaging differences between the main part and substitutes?

A: The original XRCWHT-L1-0000-006E4 packaging is listed as "-" (unspecified). All three substitute parts are supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly. This does not affect electrical or mechanical compatibility.

Q: What is the thermal resistance improvement in the substitute parts?

A: The substitute parts (XLamp® XR-E series) have thermal resistance of 8°C/W compared to 12°C/W in the original part (XLamp® XR-C series). This 33% improvement in thermal performance allows for better heat dissipation and potentially higher operating reliability in thermally constrained applications.

Q: Are all substitute parts RoHS and REACH compliant?

A: Yes. All substitute parts are RoHS Compliant, REACH Unaffected, and carry MSL 4 (72 Hours) moisture sensitivity rating, matching the compliance profile of the original part.

Q: Can I use XREWHT-L1-0000-006E5 (4000K) instead of XREWHT-L1-0000-006E4 (4500K)?

A: Substitution is possible from an electrical and mechanical standpoint, as both parts maintain identical flux output (65lm), CRI (75 Typ), and package specifications. However, the 500K difference in CCT will produce a visually warmer light output. Application-specific color temperature requirements must be evaluated before selection.
