SML-020MDTT86 Equivalent & Substitute Parts

Part Overview

The SML-020MDTT86 is an active, surface-mount LED indicator from Rohm Semiconductor featuring independent green and orange light outputs in a 1210 (3225 Metric) package. This dual-color LED is designed for discrete indication applications requiring separate green (2.2V, 20mcd) and orange (2V, 10mcd) signal outputs with clear lens optics. Finding equivalent or substitute parts may be necessary due to inventory constraints, design optimization requirements, or application-specific performance needs while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SML-020MDTT86 is determined by the following critical parameters:

• Color configuration (Green and Orange independent outputs)
• Forward voltage compatibility (2.2V Green, 2V Orange nominal)
• Test current rating (20mA for both colors)
• Surface mount technology and mounting compatibility
• RoHS3 compliance and regulatory status
• Active product status from the same manufacturer

The substitute part SML-522MD8WT86 shares the same color configuration, forward voltage specifications, test current ratings, and regulatory compliance. However, it differs in package size (0605 vs. 1210), lens transparency (diffused vs. clear), millicandela ratings, and physical dimensions. These differences establish it as a functional equivalent for applications where package miniaturization and increased brightness are acceptable trade-offs.

Parameter Comparison

Engineering Selection Recommendations

Both the SML-020MDTT86 and SML-522MD8WT86 maintain active product status from Rohm Semiconductor and comply with ROHS3 and REACH requirements. Selection between these parts should be based on:

• PCB space constraints: The SML-522MD8WT86 occupies significantly less board area (0605 package vs. 1210 package) and lower profile (0.70mm vs. 1.50mm maximum height).
• Optical requirements: The SML-020MDTT86 provides clear lens optics suitable for focused light output, while the SML-522MD8WT86 offers diffused lens characteristics for wider light distribution.
• Brightness requirements: The SML-522MD8WT86 delivers higher millicandela ratings (25mcd green, 100mcd orange) compared to the SML-020MDTT86 (20mcd green, 10mcd orange).
• Forward voltage: The SML-522MD8WT86 orange output operates at 2.2V versus 2V for the main part, requiring circuit verification for voltage-sensitive applications.

Both parts share identical test current specifications (20mA) and green forward voltage (2.2V), supporting direct electrical substitution in most indicator applications.

Frequently Asked Questions (FAQ)

Q: Can the SML-522MD8WT86 directly replace the SML-020MDTT86 in existing designs?

A: Electrical substitution is feasible due to matching color configuration, test current ratings, and green forward voltage. However, PCB layout modifications are required due to different package sizes (0605 vs. 1210). The orange forward voltage difference (2.2V vs. 2V) must be verified against circuit design specifications.

Q: What are the key differences affecting substitution?

A: The primary differences are package size, lens transparency, brightness levels, and orange forward voltage. The SML-522MD8WT86 is smaller, brighter, and features diffused optics, making it suitable for space-constrained applications requiring higher visibility.

Q: Are both parts RoHS compliant?

A: Yes, both the SML-020MDTT86 and SML-522MD8WT86 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: Which part should be selected for high-brightness indicator applications?

A: The SML-522MD8WT86 provides superior brightness with 25mcd green and 100mcd orange outputs, compared to 20mcd green and 10mcd orange for the SML-020MDTT86.

Q: Does package size affect electrical performance?

A: Package size does not affect electrical performance characteristics. Both parts operate at identical test currents and comparable forward voltages. Package selection is driven by PCB layout constraints and thermal management requirements.
