Key Parameters

Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-003A8 is determined by the following critical parameters:

• Color and correlated color temperature (CCT): Warm white 3000K
• Package format: 3529 (9073 Metric) surface mount
• Mechanical footprint: 9.00mm x 7.00mm x 4.60mm maximum height
• Electrical operating range: 350mA test current, forward voltage compatibility
• Viewing angle: 90°
• Compliance certifications: RoHS Compliant, REACH Unaffected

The substitute XREWHT-L1-0000-004E7 maintains identical package geometry, color specification, and viewing angle. Both parts operate at 350mA test current and share the same 3529 package footprint, enabling direct mechanical and thermal compatibility. Electrical parameters show minor variations within acceptable operating ranges for warm white LED applications.

Parameter Comparison

Engineering Selection Recommendations

The XREWHT-L1-0000-004E7 is a direct substitute for the obsolete XRCWHT-L1-0000-003A8 based on the following factors:

• Both parts maintain identical package geometry and surface mount footprint, ensuring PCB compatibility without layout modifications.
• Both parts are RoHS Compliant and REACH Unaffected, meeting regulatory requirements for the same application environments.
• The substitute part carries Active product status, ensuring long-term availability and supply chain continuity.
• Electrical parameters are compatible: the 0.2V reduction in forward voltage (4.6V to 3.3V) and increased flux output (49lm to 54lm) represent performance improvements within the warm white 3000K specification.
• Thermal resistance improvement (12°C/W to 8°C/W) in the substitute part provides enhanced thermal management.
• Both parts share identical MSL ratings and moisture sensitivity classifications.

Frequently Asked Questions (FAQ)

Q: Can the XREWHT-L1-0000-004E7 be used as a direct replacement without circuit modifications?

A: Yes. Both parts share identical package dimensions (9.00mm x 7.00mm x 4.60mm), mounting type (surface mount 3529), and test current (350mA). No PCB layout changes are required. The forward voltage difference (4.6V to 3.3V) is within typical LED operating tolerances and does not require circuit redesign for standard applications.

Q: What is the impact of the flux difference between the two parts?

A: The substitute part delivers 54lm versus 49lm at 350mA test current, representing approximately 10% higher luminous output. This improvement is due to the XR-E series advancement over the XR-C series. Applications requiring specific lumen output should account for this increase in brightness calculations.

Q: Are there any compliance or certification differences?

A: No. Both parts are RoHS Compliant, REACH Unaffected, and carry identical MSL ratings (4, 72 Hours). They meet the same regulatory and environmental standards.

Q: Why does the substitute part have a lower maximum current rating?

A: The substitute part (XREWHT-L1-0000-004E7) has a maximum current of 700mA compared to 500mA for the main part. This represents an increase in maximum rated current, providing greater operational headroom for the substitute part.

Q: Is the CRI specification important for substitution?

A: The substitute part specifies CRI 80 (Typ), while the main part does not provide a CRI value. For applications where color rendering index is critical, the substitute part's specified CRI 80 ensures consistent color quality. For general warm white lighting applications, this difference is not a limiting factor.
