Key Parameters

Substitute Part Grouping Explanation

The XQEROY-00-0000-000000L01 qualifies as a functional substitute based on the following alignment of critical parameters:

Matching Parameters:

• Wavelength: 458nm (450nm ~ 465nm) — identical spectral output
• Color: Blue — same color classification
• Current - Test: 350mA — identical test current
• Mounting Type: Surface Mount — compatible assembly process
• REACH Status: REACH Unaffected — equivalent regulatory compliance

Substitution Logic: The XQ-E series maintains the same blue wavelength specification and test current as the XR-C series, enabling direct functional replacement in applications requiring 458nm blue LED output at 350mA operation. Both parts are surface mount devices suitable for automated assembly. The substitute part operates within the same wavelength tolerance band and supports the same test conditions.

Parameter Comparison

Engineering Selection Recommendations

The XQEROY-00-0000-000000L01 is the designated substitute for the obsolete XRCROY-L1-0000-00701. Selection of the XQ-E variant is supported by:

• Product Status: The substitute is active and in production, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: Both parts maintain REACH Unaffected status, satisfying equivalent environmental compliance requirements.
• Spectral Compatibility: Identical wavelength specification (458nm) and tolerance band (450nm ~ 465nm) ensure color-matched output.
• Operational Compatibility: Matching test current (350mA) and wavelength enable direct functional replacement in existing circuit designs.

Design Considerations:

The substitute part operates at a lower forward voltage (3.1V vs. 4.6V) and delivers higher luminous flux (513mW vs. 275mW) at the same test current. The XQ-E package is significantly smaller (0606 vs. 3529) with improved thermal characteristics (6°C/W vs. 12°C/W). PCB layout modifications are required to accommodate the smaller package footprint. The higher maximum current rating (1A vs. 500mA) provides additional operational headroom for applications requiring increased drive current.

Frequently Asked Questions (FAQ)

Q: Can the XQEROY-00-0000-000000L01 directly replace the XRCROY-L1-0000-00701 without circuit modification?

A: The substitute maintains identical wavelength and test current specifications, enabling functional replacement. However, the lower forward voltage and smaller package require PCB layout redesign. Circuit current-limiting resistor values may require adjustment to account for the 0.4V forward voltage difference.

Q: What are the package compatibility implications?

A: The main part uses a 3529 (9073 Metric) package, while the substitute uses a 0606 (1616 Metric) package. These are physically incompatible footprints. PCB redesign is necessary to accommodate the smaller XQ-E package. The substitute's reduced height (1.73mm vs. 4.60mm) may provide assembly clearance advantages in space-constrained applications.

Q: Are there wavelength differences between the two parts?

A: Both parts operate at 458nm with identical tolerance bands (450nm ~ 465nm). No wavelength adjustment is required for color-matched applications.

Q: What is the impact of the higher luminous flux in the substitute?

A: The XQEROY-00-0000-000000L01 delivers 513mW compared to 275mW in the main part at the same 350mA test current. This represents improved efficiency and brightness. Applications requiring specific luminous output levels must account for this performance increase through circuit design adjustments.

Q: How do thermal characteristics differ?

A: The substitute exhibits superior thermal performance with a thermal resistance of 6°C/W versus 12°C/W in the main part. This allows more efficient heat dissipation and supports higher operational reliability in thermally constrained environments.

Q: Is RoHS compliance status relevant for substitution?

A: The substitute is RoHS Compliant, while the main part does not specify RoHS status. Both parts maintain REACH Unaffected status. For applications requiring RoHS compliance, the substitute provides explicit certification.
