Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SML-020MLTT86 are classified based on the following substitution criteria:

Direct Manufacturer Equivalent: Parts from the same manufacturer (Rohm Semiconductor) with identical or near-identical electrical and mechanical specifications, including forward voltage, test current, wavelength, package dimensions, and color configuration.

Parametric Equivalent: Parts with matching electrical parameters (forward voltage, test current, wavelength range) and identical package geometry, but potentially different product status or MSL rating.

Similar Substitute: Parts from alternative manufacturers with compatible electrical characteristics (forward voltage within tolerance, test current matching, wavelength in acceptable range) and equivalent package footprint, allowing direct PCB substitution with functional equivalence.

Key parameters determining substitution eligibility:

• Color configuration (Green/Red independent)
• Forward voltage (Vf): 2.2V Green, 1.75V Red ±0.25V tolerance
• Test current: 20mA
• Package footprint: 1210 (3225 Metric) or 4-SMD equivalent
• Lens transparency: Clear
• Mounting type: Surface Mount
• Wavelength range: 570nm Green, 660nm Red ±10nm

Parameter Comparison

Engineering Selection Recommendations

S7L-020MLTT86NN (Rohm Semiconductor): Direct manufacturer equivalent with Active product status. Offers improved MSL rating (3 vs. 4) and extended moisture protection window (168 hours vs. 72 hours). Recommended for new production runs and long-term supply continuity. Detailed electrical specifications not provided in available documentation; verification with manufacturer datasheet required before implementation.

SML-020MLTT87 (Rohm Semiconductor): Parametric equivalent within the same SML-020 series. Maintains identical electrical characteristics (2.2V Green, 1.75V Red, 20mA test current, 20mcd/16mcd brightness) and package geometry. Carries "Not For New Designs" status matching the primary part. MSL rating improved to 3 (168 hours). Direct pin-compatible replacement for existing designs.

5977701507F (Dialight): Alternative manufacturer substitute with Active product status and ROHS3 compliance. Maintains compatible forward voltage (2.2V Green, 2.0V Red within tolerance), test current (20mA), and package footprint (3.00mm x 2.50mm). Red wavelength (650nm) differs slightly from primary part (660nm). Height reduced to 1.30mm. Viewing angle specification (100°) provided. Suitable for applications where brightness tolerance and wavelength variation are acceptable.

5977721507F (Dialight): Alternative manufacturer substitute with Active product status. Green/Yellow color configuration differs from primary Green/Red specification. Forward voltage for yellow element (2.1V) differs from red (1.75V). Brightness ratings (21mcd Green, 10mcd Yellow) vary from primary part. Not recommended for direct substitution in applications requiring red indication; suitable only for designs where yellow indication is functionally equivalent.

7016X1/5 (Visual Communications Company - VCC): Alternative manufacturer substitute with Active product status and superior MSL rating (2, 1 Year). Maintains Green/Red color configuration with compatible forward voltage (2.2V Green, 1.75V Red) and test current (20mA). Brightness ratings lower than primary part (14.5mcd Green, 12.5mcd Red). Height reduced to 1.30mm. Viewing angle (110°) exceeds primary part specification. Suitable for applications with relaxed brightness requirements and extended moisture protection needs.

Frequently Asked Questions (FAQ)

Q: Can SML-020MLTT87 be used as a direct replacement for SML-020MLTT86?

A: Yes. Both parts are from the same SML-020 series manufactured by Rohm Semiconductor with identical electrical parameters (2.2V Green, 1.75V Red, 20mA test current, 20mcd/16mcd brightness) and package geometry (1210, 3.00mm x 2.50mm x 1.50mm). Pin configuration and PCB footprint are compatible. The primary difference is improved MSL rating (3 vs. 4).

Q: Are Dialight 5977701507F and 5977721507F interchangeable with the primary part?

A: 5977701507F maintains Green/Red color configuration and is functionally compatible with matching forward voltage (2.2V Green, 2.0V Red) and test current (20mA). However, red wavelength differs (650nm vs. 660nm) and brightness is lower (16mcd/6.3mcd vs. 20mcd/16mcd). 5977721507F uses Green/Yellow configuration and is not suitable for applications requiring red indication.

Q: What is the impact of different package heights on PCB assembly?

A: The primary part SML-020MLTT86 has maximum height of 1.50mm. Alternative substitutes from Dialight (5977701507F, 5977721507F) and VCC (7016X1/5) have reduced height of 1.30mm. This 0.20mm difference may affect solder reflow profiles and clearance calculations in high-density assemblies. Verify PCB design clearances before substitution.

Q: Does MSL rating affect part selection?

A: Yes. The primary part carries MSL 4 (72-hour protection window), while most substitutes offer MSL 3 (168 hours). VCC 7016X1/5 provides MSL 2 (1-year protection). Higher MSL ratings provide extended moisture protection and reduce risk of moisture-induced failures during storage and assembly. Selection depends on storage conditions, assembly timeline, and manufacturing environment.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (S7L-020MLTT86NN, SML-020MLTT87, 5977701507F, 5977721507F, 7016X1/5) carry ROHS3 Compliant certification, matching the primary part SML-020MLTT86. All parts are REACH Unaffected and classified as EAR99 for export control purposes.

Q: What is the significance of "Not For New Designs" product status?

A: This status indicates the part is in mature/end-of-life phase and is not recommended for new product development. However, it remains available for existing production support. For new designs, prioritize Active status alternatives such as S7L-020MLTT86NN, 5977701507F, 5977721507F, or 7016X1/5.

Q: How do brightness ratings (millicandela) affect visual indication performance?

A: The primary part provides 20mcd Green and 16mcd Red brightness. Substitutes vary: SML-020MLTT87 matches exactly; 5977701507F provides 16mcd/6.3mcd (lower red brightness); 5977721507F provides 21mcd/10mcd (yellow instead of red); 7016X1/5 provides 14.5mcd/12.5mcd (lower overall). Lower brightness may reduce visibility in high ambient light conditions. Verify application requirements before selecting lower-brightness alternatives.
