Substitute Part Grouping Explanation

Substitution of MLCROY-A1-0000-000201 is determined by the following critical parameters:

• Manufacturer and Series: Both parts must be CreeLED XLamp® ML-E series to ensure optical and thermal characteristics alignment
• Color and Wavelength: Blue color with 458nm dominant wavelength within acceptable tolerance bands
• Package and Mechanical Compatibility: Identical 4-SMD J-Lead Exposed Pad configuration with matching footprint dimensions (4.60mm x 3.15mm) and height (1.33mm maximum)
• Electrical Characteristics: Forward voltage (Vf) of 3.2V typical and viewing angle of 125° must be maintained
• Thermal Performance: Thermal resistance within acceptable range for thermal management design

The substitute part MLEROY-A1-0000-000405 meets all these criteria while offering improved performance characteristics and active product status.

Engineering Selection Recommendations

MLEROY-A1-0000-000405 is the direct substitute for MLCROY-A1-0000-000201. Selection is based on the following engineering factors:

• Product Status: The original part is Obsolete, while the substitute is Active. Active product status ensures continued availability, manufacturing support, and compliance with current regulatory standards.
• Regulatory Compliance: The substitute is RoHS Compliant, whereas the original part carries REACH Unaffected status. RoHS compliance is a requirement for many applications and markets.
• Mechanical and Electrical Compatibility: Both parts share identical package configuration, footprint dimensions, height, forward voltage, and viewing angle, ensuring direct PCB-level compatibility without design modification.
• Thermal Performance: The substitute offers improved thermal resistance (11°C/W versus 13°C/W), providing better heat dissipation characteristics in thermal-constrained applications.
• Performance Enhancement: The substitute supports higher maximum current (350mA versus 250mA) and delivers increased luminous flux (161mW versus 111mW at respective test currents), enabling improved optical output when required.

Frequently Asked Questions (FAQ)

Q: Can MLEROY-A1-0000-000405 be used as a direct replacement for MLCROY-A1-0000-000201 without PCB modifications?

A: Yes. Both parts use identical 4-SMD J-Lead Exposed Pad packaging with matching footprint dimensions (4.60mm x 3.15mm) and height (1.33mm). No PCB layout changes are required for mechanical compatibility.

Q: What are the key differences between these two parts?

A: The substitute offers improved performance and compliance: higher maximum current rating (350mA versus 250mA), increased luminous flux output (161mW versus 111mW at respective test currents), better thermal resistance (11°C/W versus 13°C/W), and RoHS compliance. Both maintain identical forward voltage (3.2V) and viewing angle (125°).

Q: Why is the original part classified as Obsolete?

A: Product obsolescence indicates that the manufacturer has discontinued production. MLEROY-A1-0000-000405 is the active equivalent, ensuring continued supply and manufacturing support.

Q: Are the wavelength specifications compatible?

A: Yes. The original part specifies 458nm (450nm ~ 465nm), while the substitute specifies 458nm (455nm ~ 460nm). The substitute's tighter tolerance band falls entirely within the original specification range, ensuring optical compatibility.

Q: What is the impact of the improved thermal resistance in the substitute?

A: Lower thermal resistance (11°C/W versus 13°C/W) means the substitute dissipates heat more efficiently. This reduces junction temperature rise under the same operating conditions, improving reliability and potentially extending operational life in thermally constrained designs.

Q: Does the higher maximum current rating of the substitute affect circuit design?

A: The substitute's higher maximum current rating (350mA versus 250mA) provides additional design margin and operational flexibility. Existing circuits designed for the original part will operate within safe limits on the substitute. Higher current capability does not require circuit modification unless increased optical output is desired.

Q: Are moisture sensitivity levels identical?

A: Yes. Both parts carry MSL 2A (4 Weeks) rating, requiring identical moisture control and handling procedures during storage and assembly.
