LED LUXEON T Blue 453nm (LXH1-FWRB) Equivalent & Substitute Parts

Part Overview

The LXH1-FWRB is a LUXEON T series blue LED operating at 453nm (445nm–460nm wavelength range) in a 1515 (3838 Metric) surface mount package. This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The part delivers 1040mW typical luminous flux at 700mA test current with a forward voltage of 2.8V and 120° viewing angle. Finding suitable alternatives ensures design continuity and supply chain reliability for applications requiring blue LED performance in this wavelength and package class.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LXH1-FWRB is determined by the following critical parameters:

• Wavelength Compatibility: Blue LED color range 445nm–460nm ensures optical performance alignment
• Forward Voltage (Vf): Typical value 2.8V allows direct circuit integration without redesign
• Current Ratings: Test current 700mA and maximum current 1.05A define safe operating envelope
• Package Classification: Surface mount technology in 1515 (3838 Metric) or compatible footprint
• Thermal Characteristics: Thermal resistance and test temperature stability at 85°C
• Compliance Standards: RoHS3 and REACH compliance for regulatory continuity
• Luminous Flux Output: Performance level approximately 1040mW at specified test conditions

The XTEARY-00-0000-000000N02 (CreeLED XLamp XT-E Blue 455nm) qualifies as a manufacturer-recommended substitute based on wavelength overlap (450nm–460nm range), compatible forward voltage (2.85V), surface mount configuration (1414/3535 Metric package), and active product status with full compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The LXH1-FWRB is obsolete, while the XTEARY-00-0000-000000N02 maintains active status with ongoing manufacturer support and availability. This transition ensures long-term supply chain stability.

Compliance Alignment: Both parts meet RoHS and REACH regulatory requirements. The substitute carries RoHS Compliant certification (versus ROHS3 for the main part), maintaining environmental and safety compliance standards across jurisdictions.

Optical Performance: Wavelength ranges overlap significantly (445–460nm for LXH1-FWRB; 450–460nm for XTEARY-00-0000-000000N02), with center wavelengths separated by only 2nm (453nm vs. 455nm). Forward voltage compatibility (2.8V vs. 2.85V) permits direct circuit substitution without voltage regulation modifications.

Thermal and Electrical Characteristics: The substitute exhibits higher maximum current rating (1.5A vs. 1.05A) and wider viewing angle (140° vs. 120°), providing design flexibility. Thermal resistance difference (5°C/W vs. 3°C/W) requires thermal management evaluation in high-power continuous-duty applications.

Package Footprint: The substitute uses a smaller 1414 (3535 Metric) package versus the main part's 1515 (3838 Metric). PCB layout verification is required to confirm mechanical compatibility, though both are standard surface mount configurations.

Frequently Asked Questions (FAQ)

Q: Can the XTEARY-00-0000-000000N02 be used as a direct drop-in replacement for the LXH1-FWRB?

A: Electrical substitution is viable due to wavelength overlap (450–460nm range), matching forward voltage (2.8V vs. 2.85V), and compatible current ratings. However, the package footprint differs (1414 vs. 1515 Metric), requiring PCB layout verification. Thermal resistance is higher (5°C/W vs. 3°C/W), necessitating thermal analysis for high-current applications.

Q: What are the key wavelength compatibility criteria?

A: Both parts operate within the blue LED spectrum (445–460nm range). The LXH1-FWRB center wavelength is 453nm; the substitute is 455nm. This 2nm difference is within typical manufacturing tolerance and produces no perceptible color shift in most applications.

Q: How do the luminous flux outputs compare?

A: The LXH1-FWRB delivers 1040mW at 700mA test current. The XTEARY-00-0000-000000N02 delivers 563mW at 350mA test current. Direct output comparison requires normalization to equivalent current levels; the substitute's higher maximum current rating (1.5A) allows operation at higher power levels if thermal design permits.

Q: Are there package compatibility concerns?

A: The main part uses 1515 (3838 Metric) packaging; the substitute uses 1414 (3535 Metric). Both are standard surface mount configurations. PCB footprint, solder pad layout, and pick-and-place equipment compatibility must be verified before production transition.

Q: Do compliance certifications differ between the parts?

A: Both parts are RoHS and REACH compliant. The main part carries ROHS3 certification; the substitute carries RoHS Compliant status. Both meet EAR99 export classification and 8541.41.0000 HTSUS coding. Compliance requirements for your application determine if this distinction is material.

Q: What thermal considerations apply to substitution?

A: The LXH1-FWRB has 3°C/W thermal resistance; the XTEARY-00-0000-000000N02 has 5°C/W. In high-current or continuous-duty applications, the substitute generates higher junction temperature rise per watt dissipated. Thermal modeling and PCB thermal design review are recommended for applications operating near maximum current ratings.
