Key Parameters

Substitute Part Grouping Explanation

Substitution of the OVS5MGBCR4 is determined by the following critical parameters:

Package Compatibility: The substitute must use the 1414 (3535 Metric) surface mount package to ensure mechanical fit and thermal interface compatibility with existing PCB layouts and assembly processes.

Wavelength Range: The substitute must operate within the green spectrum. The OVS5MGBCR4 operates at 528nm (520nm ~ 535nm). Acceptable substitutes must maintain wavelength compatibility within the visible green range (520nm ~ 540nm).

Electrical Performance: The substitute must support operation at or near the test current of 150mA with forward voltage characteristics compatible with existing circuit designs. Maximum current ratings must not fall below the application requirements.

Mounting and Thermal Characteristics: Surface mount configuration and thermal resistance must be compatible with the application's thermal management design.

Compliance and Status: The substitute must maintain RoHS3 compliance and REACH unaffected status to meet regulatory requirements.

The L135-G525003500000 (Lumileds LUXEON 3535L) meets all substitution criteria through identical package geometry, compatible wavelength specification (530nm, 520nm ~ 540nm), surface mount configuration, and equivalent regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The L135-G525003500000 is the qualified substitute for the obsolete OVS5MGBCR4. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and production continuity.

The substitute operates at a lower test current (100mA versus 150mA) with a reduced maximum current rating (125mA versus 180mA). Circuit designs must be evaluated to confirm that the substitute's current characteristics are compatible with existing current-limiting resistor values and power supply specifications.

The substitute exhibits lower thermal resistance (42°C/W versus 5°C/W), which may affect thermal management calculations in high-power applications. The reduced seated height (0.90mm versus 1.40mm) is compatible with standard PCB assembly processes and does not present mechanical interference concerns.

The wavelength specifications overlap within the green spectrum (528nm versus 530nm), with both parts operating within acceptable ranges for general green LED applications. The substitute delivers higher luminous efficiency (69 lm/W versus 47 lm/W) at its rated test current.

Frequently Asked Questions (FAQ)

Q: Can the L135-G525003500000 be used as a direct replacement for the OVS5MGBCR4 without circuit modification?

A: The L135-G525003500000 is mechanically and electrically compatible in terms of package geometry and wavelength. However, the substitute operates at lower maximum current (125mA versus 180mA). Circuit designs using the OVS5MGBCR4 at currents above 125mA require current adjustment through resistor value changes or power supply reconfiguration.

Q: What are the key differences in electrical performance?

A: The substitute operates at 100mA test current compared to the main part's 150mA. Forward voltage is slightly lower (3.2V versus 3.4V). Luminous flux at the substitute's rated current is 22lm versus 24lm at the main part's rated current. The substitute delivers superior efficiency (69 lm/W versus 47 lm/W).

Q: Are there package compatibility concerns?

A: Both components use the 1414 (3535 Metric) surface mount package. Dimensional differences are minimal (width 3.40mm versus 4.60mm, height 0.90mm versus 1.40mm). These variations are within standard PCB assembly tolerances and do not require layout modifications.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the OVS5MGBCR4 and L135-G525003500000 are ROHS3 compliant and REACH unaffected, satisfying current regulatory requirements for electronic component use.

Q: What is the impact of the different thermal resistance values?

A: The substitute has higher thermal resistance (42°C/W versus 5°C/W). In applications with continuous high-current operation, thermal management calculations must be recalculated. For typical indicator and general lighting applications, this difference does not present practical thermal concerns.

Q: How do the viewing angles compare?

A: The main part provides 120° viewing angle while the substitute provides 115°. This 5° difference is negligible for most applications and does not affect optical performance in standard indicator or general lighting configurations.
