Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SML-020PDTT87 is determined by the following critical parameters:

Primary Substitution Criteria:

• Surface mount mounting type
• Dual independent color configuration
• Forward voltage compatibility (2.0V to 2.2V range)
• Test current of 20mA per color
• Clear lens transparency
• Physical dimensions within 3.00mm L x 2.50mm W footprint
• RoHS3 compliance
• REACH unaffected status

Substitute Categories:

Direct Equivalent: S7L-020PDTT87JM (Rohm Semiconductor) - Same manufacturer, same base product series, active production status, identical electrical specifications.

Similar Substitutes: Parts from Dialight (5977701502F, 5977701507F, 5977721502F, 5977721507F) and Rohm Semiconductor (SML-522MU8WT86) meet the core electrical and mechanical compatibility requirements, though with variations in color combinations, millicandela ratings, and package designations.

Parameter Comparison

Engineering Selection Recommendations

S7L-020PDTT87JM is the primary recommended substitute. It is manufactured by Rohm Semiconductor, the same original manufacturer, maintains active production status, and carries identical RoHS3 compliance and REACH unaffected certifications. This part provides the highest assurance of functional and electrical compatibility.

Dialight 597 Series parts (5977701502F, 5977701507F, 5977721502F, 5977721507F) are secondary alternatives. All maintain RoHS3 compliance and REACH unaffected status with active production. These parts meet the core electrical parameters (forward voltage and test current) and physical footprint requirements. Color variations (red/yellow substitution for orange) and millicandela rating differences must be evaluated against specific application requirements.

SML-522MU8WT86 is a tertiary option from Rohm Semiconductor with active production status and full compliance certifications. This part features significantly higher millicandela ratings (40mcd green, 63mcd red) and a smaller physical footprint (1.50mm L x 1.30mm W, 0.70mm height), making it suitable only for applications where increased brightness and reduced board space are acceptable design modifications.

Frequently Asked Questions (FAQ)

Q: Can S7L-020PDTT87JM be used as a direct replacement for SML-020PDTT87?

A: Yes. S7L-020PDTT87JM is the direct equivalent from the same manufacturer with identical base product series designation and active production status. Both parts maintain RoHS3 compliance and REACH unaffected certifications.

Q: What are the key differences between the main part and Dialight substitutes?

A: Dialight parts maintain compatible forward voltage (2.0V to 2.2V), test current (20mA), and physical dimensions (3.00mm L x 2.50mm W). Primary differences include color combinations (red or yellow instead of orange), millicandela ratings (6.3mcd to 21mcd versus 4mcd to 10mcd), and packaging format (strip or tape & reel).

Q: Is SML-522MU8WT86 suitable for direct PCB replacement?

A: No. SML-522MU8WT86 has significantly different physical dimensions (1.50mm L x 1.30mm W versus 3.00mm L x 2.50mm W) and height (0.70mm versus 1.50mm). PCB layout modifications are required. This part is suitable only when board space reduction and increased brightness are design objectives.

Q: Do all substitute parts meet compliance requirements?

A: Yes. All listed substitute parts are RoHS3 compliant and REACH unaffected, matching the original part's regulatory status.

Q: What is the impact of color substitution (orange to red or yellow)?

A: Color substitution affects visual indication functionality. Applications requiring specific orange wavelength output must use parts with orange color specification. Red (653nm) and yellow (589nm) alternatives have different dominant wavelengths and may not provide equivalent visual indication in the target application.

Q: Which substitute offers the best long-term availability?

A: SML-522MU8WT86 has the highest current inventory (163,519 pieces) with active production status, providing the strongest long-term supply assurance. However, physical footprint differences require design modification.
