Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMLE12EC6TT86 is determined by the following critical parameters:

• Package Compatibility: 0603 (1608 Metric) surface mount package with identical footprint dimensions (1.60mm L x 0.80mm W)
• Electrical Compatibility: 3V forward voltage and 5mA test current operation
• Optical Characteristics: Green color emission within the visible spectrum
• Mechanical Fit: Maximum height constraint of 0.46mm or less to ensure PCB assembly compatibility
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The SMLEN3EC8TT86 meets all substitution criteria as an active product from the same manufacturer and series, maintaining identical package geometry, electrical operating parameters, and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

The SMLEN3EC8TT86 is the direct substitute for the obsolete SMLE12EC6TT86. Both components share identical package geometry, electrical operating parameters (3V forward voltage, 5mA test current), and regulatory compliance certifications (ROHS3 Compliant, REACH Unaffected). The substitute part maintains active product status with Rohm Semiconductor, ensuring long-term availability and supply chain continuity.

The SMLEN3EC8TT86 delivers increased luminous intensity (140mcd versus 85mcd) while maintaining the same forward voltage and test current specifications. The substitute part exhibits a lower maximum height (0.40mm versus 0.46mm), providing improved PCB assembly clearance. The MSL rating difference (MSL 3 versus MSL 1) requires standard moisture control during storage and handling but does not affect functional compatibility in typical operating environments.

Frequently Asked Questions (FAQ)

Q: Can SMLEN3EC8TT86 be used as a direct replacement for SMLE12EC6TT86 in existing designs?

A: Yes. Both parts share identical 0603 (1608 Metric) package dimensions, 3V forward voltage, and 5mA test current specifications. PCB footprints and circuit designs require no modification.

Q: What is the difference in brightness between these two parts?

A: The SMLEN3EC8TT86 produces 140mcd compared to 85mcd for the SMLE12EC6TT86. This increased luminous intensity may affect visual perception in the application. Circuit current limiting resistor values should be verified to ensure the design accommodates the higher brightness output.

Q: Are there any height compatibility concerns?

A: The SMLEN3EC8TT86 has a maximum height of 0.40mm versus 0.46mm for the SMLE12EC6TT86. The substitute part is 0.06mm shorter, providing additional clearance for PCB assembly and component stacking.

Q: What is the significance of the different MSL ratings?

A: SMLE12EC6TT86 carries MSL 1 (Unlimited moisture exposure tolerance), while SMLEN3EC8TT86 carries MSL 3 (168-hour moisture exposure limit). Standard moisture control during storage and handling is required for the substitute part. This does not affect functional performance in normal operating conditions.

Q: Are both parts RoHS compliant?

A: Yes. Both SMLE12EC6TT86 and SMLEN3EC8TT86 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: Why is the original part obsolete?

A: The SMLE12EC6TT86 is classified as obsolete by Rohm Semiconductor. The SMLEN3EC8TT86 represents the active product continuation within the EXCELED™ series, offering improved specifications and guaranteed long-term availability.
