SML-020MLTT87 Equivalent & Substitute Parts

Part Overview

The SML-020MLTT87 is a dual-color surface mount LED indicator from Rohm Semiconductor, combining independent green and red LED elements in a 1210 (3225 Metric) package. This component provides discrete color indication with green emission at 570nm and red emission at 660nm. The part is classified as Not For New Designs, necessitating identification of equivalent and substitute components for ongoing production requirements and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SML-020MLTT87 are identified based on the following critical parameters that determine functional compatibility:

Direct Equivalent Criteria:

• Dual-color green and red LED configuration
• Independent color operation
• Surface mount technology
• RoHS3 compliance and MSL 3 rating
• Rohm Semiconductor manufacturer

Allowed Variation Parameters:

• Package size (different 1210 variants or smaller packages acceptable with circuit redesign)
• Lens transparency (clear or diffused acceptable depending on application)
• Forward voltage within operational range (2.2V Green acceptable; Red voltage 1.75V to 2.2V acceptable)
• Millicandela rating (brightness variation acceptable if minimum visibility requirements met)
• Wavelength peak (green 570-572nm acceptable; red 620-660nm acceptable)

Non-Negotiable Parameters:

• Dual independent color configuration
• Surface mount technology
• RoHS3 and MSL 3 compliance
• Rohm Semiconductor source

Engineering Selection Recommendations

S7L-020MLTT87MM (Direct Equivalent): This part maintains active product status with Rohm Semiconductor and carries identical RoHS3 and MSL 3 compliance. The S7L-020MLTT87MM represents the direct successor to the SML-020MLTT87, with equivalent package and functional characteristics. Selection of this part eliminates obsolescence risk while maintaining design compatibility.

SML-522MU8WT86 (Similar Substitute): This part provides functional substitution with the following considerations: the 0605 (1513 Metric) package is significantly smaller than the 1210 package, requiring PCB layout and circuit redesign. The diffused lens provides light diffusion compared to the clear lens of the original part. Forward voltage for red increases to 2.2V (from 1.75V), requiring circuit current-limiting adjustment. Millicandela ratings are higher (40mcd green, 63mcd red versus 20mcd and 16mcd), providing increased brightness. Wavelength peak for red shifts to 620nm (from 660nm). This part is suitable only when PCB space constraints justify redesign effort and the higher brightness and diffused lens characteristics align with application requirements.

Frequently Asked Questions (FAQ)

Q: Can the S7L-020MLTT87MM be used as a direct drop-in replacement for the SML-020MLTT87?

A: The S7L-020MLTT87MM is designed as the direct equivalent with matching package and functional specifications. Verification of PCB footprint compatibility is required before implementation.

Q: What are the key differences between the SML-522MU8WT86 and the original SML-020MLTT87?

A: The SML-522MU8WT86 differs in three critical areas: package size (0605 versus 1210, requiring PCB redesign), lens type (diffused versus clear, affecting light distribution), and electrical parameters (red forward voltage 2.2V versus 1.75V, requiring circuit adjustment). Brightness is higher with 40mcd green and 63mcd red compared to 20mcd and 16mcd.

Q: Is the SML-522MU8WT86 suitable for new designs?

A: The SML-522MU8WT86 carries active product status and is suitable for new designs. However, the smaller package and diffused lens require that application requirements specifically accommodate these characteristics.

Q: What compliance certifications apply to all substitute parts?

A: All parts listed maintain RoHS3 compliance and MSL 3 (168 Hours) moisture sensitivity rating, meeting current regulatory requirements for electronic component manufacturing and assembly.

Q: Does package size affect electrical performance?

A: Package size does not affect electrical performance characteristics. However, smaller packages may present thermal management considerations in high-current applications. The SML-522MU8WT86 operates at identical test current (20mA) as the original part.

Q: Can the SML-522MU8WT86 be used in applications requiring a clear lens?

A: The SML-522MU8WT86 features a diffused lens, which scatters light differently than a clear lens. Applications requiring specific light distribution patterns or clear lens characteristics should use the S7L-020MLTT87MM instead.
