Engineering Selection Recommendations

The MLEROY-A1-0000-000403 is the direct substitute for the obsolete MLCROY-A1-0000-000203. Selection is based on the following engineering criteria:

Product Status: The substitute part carries Active product status, ensuring long-term availability and continued manufacturer support, whereas the main part is classified as Obsolete.

Compliance & Certifications: The substitute part is RoHS Compliant, providing regulatory advantage for applications subject to environmental compliance requirements. Both parts maintain identical REACH Unaffected and ECCN EAR99 classifications.

Electrical Performance: The substitute part provides enhanced electrical characteristics with increased test current (150mA vs. 100mA), higher maximum current rating (350mA vs. 250mA), and proportionally increased luminous flux output (161mW vs. 111mW). Forward voltage remains identical at 3.2V, ensuring direct circuit compatibility.

Thermal Performance: The substitute part demonstrates improved thermal characteristics with reduced thermal resistance (11°C/W vs. 13°C/W), supporting higher power dissipation and extended operational reliability.

Physical & Mechanical Compatibility: Both parts maintain identical package configuration, footprint dimensions, and mounting characteristics, enabling direct PCB-level substitution without layout modification.

Packaging Format: The substitute part is supplied in Tape & Reel (TR) format, standard for high-volume production environments.

Frequently Asked Questions (FAQ)

Q: Can MLEROY-A1-0000-000403 be used as a direct replacement for MLCROY-A1-0000-000203 on existing PCBs?

A: Yes. Both parts share identical package configuration (4-SMD, J-Lead Exposed Pad), footprint dimensions (4.60mm × 3.15mm), and mounting height (1.33mm maximum). PCB layout modification is not required.

Q: What are the key differences between these parts?

A: The substitute part provides enhanced electrical performance (higher test current and maximum current ratings), improved thermal characteristics (lower thermal resistance), active product status, and RoHS compliance. Forward voltage and wavelength specifications remain identical.

Q: Is the increased luminous flux output of the substitute part compatible with existing circuit designs?

A: The substitute part operates at identical forward voltage (3.2V) and maintains the same wavelength specification (460nm, 455nm–465nm). Circuit designs using current-limiting resistors or constant-current drivers will function correctly. Applications with fixed-voltage supplies should verify that the increased luminous flux output is acceptable for the intended application.

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

A: Lower thermal resistance (11°C/W vs. 13°C/W) indicates more efficient heat dissipation from the LED junction to the PCB. This characteristic supports higher sustained power levels and extended operational life in thermally constrained environments.

Q: Are both parts subject to the same moisture sensitivity requirements?

A: Yes. Both parts carry identical Moisture Sensitivity Level (MSL) rating of 2A (4 Weeks), requiring identical storage and handling protocols.

Q: What is the advantage of RoHS compliance in the substitute part?

A: RoHS compliance ensures the part meets regulatory requirements for hazardous substance restrictions in electrical and electronic equipment, particularly for applications subject to EU RoHS Directive or equivalent regional regulations.

Q: Can the substitute part be used in applications originally designed for the main part if the circuit operates at lower current levels?

A: Yes. The substitute part is backward compatible. Applications operating at or below the original test current (100mA) will function identically. The enhanced maximum current rating provides design flexibility for future applications without requiring component substitution.
