XRCROY-L1-0000-00702 Equivalent & Substitute Parts

Part Overview

The XRCROY-L1-0000-00702 is an XLamp® XR-C Blue LED operating at 455nm wavelength in a 3529 (9073 Metric) surface mount package. This part is classified as obsolete, making identification of suitable substitute components essential for ongoing production and design requirements. The XR-C series has been superseded by newer XLamp® generations, necessitating alternative part selection for new designs and inventory replenishment.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the XRCROY-L1-0000-00702 is determined by the following critical parameters:

Color and Wavelength Compatibility: The substitute must emit blue light within the 450nm to 465nm range to maintain optical performance in the target application.

Electrical Characteristics: The substitute must operate at the same test current (350mA) with forward voltage and maximum current ratings compatible with existing circuit designs.

Luminous Flux Performance: The substitute must deliver comparable light output at the specified test conditions to ensure functional equivalence.

Mounting and Package Considerations: Surface mount technology is required. While the original uses a 3529 package, substitutes in smaller packages (such as 0606) are acceptable provided the PCB layout can accommodate the dimensional change.

Compliance and Regulatory Status: The substitute must maintain equivalent REACH and ECCN classifications to ensure regulatory compliance.

The XQEROY-00-0000-000000L01 meets these substitution criteria through compatible wavelength, electrical operation at the same test current, superior luminous flux output, and active product status with full compliance documentation.

Parameter Comparison

Engineering Selection Recommendations

The XQEROY-00-0000-000000L01 is the designated substitute for the obsolete XRCROY-L1-0000-00702. Selection is based on the following engineering factors:

Product Status: The XQEROY operates as an active product with ongoing manufacturer support, whereas the XRCROY is obsolete and subject to discontinuation.

Regulatory Compliance: Both parts maintain REACH Unaffected and EAR99 classifications. The XQEROY additionally carries RoHS Compliance certification, meeting stricter environmental standards for new designs.

Electrical Compatibility: Both parts operate at identical test current (350mA). The XQEROY exhibits lower forward voltage (3.1V vs. 4.6V) and higher maximum current rating (1A vs. 500mA), providing improved circuit flexibility.

Optical Performance: The XQEROY delivers 513mW luminous flux compared to 275mW in the original, representing an 86% increase in light output at equivalent test conditions. Wavelength remains within the specified blue range (458nm vs. 455nm).

Thermal Characteristics: The XQEROY features superior thermal resistance (6°C/W vs. 12°C/W), enabling better heat dissipation in high-power applications.

Package Transition: The XQEROY uses a 0606 (1616 Metric) package, significantly smaller than the original 3529 package. PCB layout modification is required to accommodate this dimensional change.

Frequently Asked Questions (FAQ)

Q: Can the XQEROY-00-0000-000000L01 directly replace the XRCROY-L1-0000-00702 without circuit modification?

A: Electrical substitution is possible due to identical test current operation and compatible forward voltage characteristics. However, the package size reduction from 3529 to 0606 requires PCB layout redesign. The lower forward voltage of the XQEROY may require minor current-limiting resistor adjustment depending on circuit topology.

Q: What are the key differences in optical performance between these parts?

A: The XQEROY delivers 513mW luminous flux versus 275mW in the XRCROY at the same 350mA test current, representing significantly higher light output. Wavelength separation is minimal (458nm vs. 455nm), both within the blue spectrum range. Viewing angle increases from 100° to 125°, providing wider light distribution.

Q: Are there compliance or regulatory differences between the original and substitute?

A: Both parts maintain identical REACH Unaffected and EAR99 classifications. The XQEROY additionally carries RoHS Compliance certification, making it suitable for applications with stricter environmental requirements. No regulatory barriers exist to substitution.

Q: What thermal considerations apply to this substitution?

A: The XQEROY exhibits superior thermal resistance (6°C/W vs. 12°C/W), meaning it dissipates heat more efficiently. This improvement allows operation at higher ambient temperatures or higher drive currents without exceeding thermal limits.

Q: Is the package size change from 3529 to 0606 a significant design constraint?

A: Yes. The XQEROY is substantially smaller (1.60mm x 1.60mm vs. 9.00mm x 7.00mm), requiring PCB footprint redesign. Assembly equipment compatibility must be verified for the smaller 0606 package. This change is not suitable for direct board-level substitution without layout modification.

Q: Can the XQEROY operate at higher currents than the original part?

A: Yes. The XQEROY maximum current rating is 1A compared to 500mA in the XRCROY. However, operation above 350mA test current requires thermal management verification and may affect luminous flux output characteristics.
