SML-P12YTT86 Yellow LED 0402 SMD Equivalent & Substitute Parts

Part Overview

The SML-P12YTT86 is a yellow 590nm LED indicator in 0402 (1006 Metric) surface mount package manufactured by Rohm Semiconductor under the PicoLED™ series. This component is rated at 100mcd with a forward voltage of 2.1V at 20mA test current and features a square lens with flat top in a clear colorless configuration.

The SML-P12YTT86 carries a "Not For New Designs" product status, indicating it has been superseded in Rohm's current product portfolio. For new design implementations and long-term supply chain stability, identifying active equivalent alternatives is essential for production continuity and component availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SML-P12YTT86 is determined by strict parametric matching across the following critical criteria:

Mandatory Matching Parameters:

• Color: Yellow
• Wavelength - Dominant: 590nm
• Millicandela Rating: 100mcd
• Voltage - Forward (Vf) Typical: 2.1V
• Current - Test: 20mA
• Package / Case: 0402 (1006 Metric)
• Lens Style: Square with Flat Top
• Lens Color: Colorless
• Lens Transparency: Clear
• Mounting Type: Surface Mount
• Physical Dimensions: 1.00mm L x 0.60mm W
• Height (Max): 0.25mm
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 3 (168 Hours)

All substitute parts must match these parameters without deviation to ensure direct functional and mechanical compatibility in existing PCB designs and assembly processes.

Parameter Comparison

Engineering Selection Recommendations

The SML-P12YTT86R is the direct parametric equivalent and recommended substitute for the SML-P12YTT86. Both components are manufactured by Rohm Semiconductor within the PicoLED™ series and share identical electrical and mechanical specifications.

The primary distinction is product lifecycle status: SML-P12YTT86 is designated "Not For New Designs," while SML-P12YTT86R maintains "Active" status. This designation indicates that SML-P12YTT86R represents the current production alternative with assured long-term availability and supply chain support.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and consumer applications. The identical MSL rating of 3 (168 Hours) ensures equivalent moisture handling and storage requirements.

For new product designs and production transitions, SML-P12YTT86R is the appropriate selection. For existing inventory management of legacy designs using SML-P12YTT86, the SML-P12YTT86R provides direct drop-in compatibility without circuit or PCB modifications.

Frequently Asked Questions (FAQ)

Q: Can SML-P12YTT86R be used as a direct replacement for SML-P12YTT86 in existing designs?

A: Yes. The SML-P12YTT86R is a parametric equivalent with identical electrical characteristics (2.1V forward voltage, 20mA test current, 100mcd brightness), optical properties (590nm yellow wavelength, clear square lens), and mechanical specifications (0402 package, 1.00mm x 0.60mm x 0.25mm height). No circuit modifications or PCB layout changes are required.

Q: What is the significance of the "Not For New Designs" status on SML-P12YTT86?

A: This designation indicates the part has been superseded in Rohm's current product portfolio. While existing inventory may remain available, the manufacturer recommends using SML-P12YTT86R for new product development to ensure long-term supply chain continuity and access to manufacturing support.

Q: Are there any differences in packaging or handling between these two parts?

A: Both parts are supplied in Tape & Reel (TR) packaging with identical MSL rating of 3 (168 Hours). Storage, handling, and moisture control requirements are equivalent.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both SML-P12YTT86 and SML-P12YTT86R are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for industrial and consumer electronics applications.

Q: What is the base product number for these components?

A: Both parts share the base product number SML-P12, with the suffix designating specific optical and packaging configurations within the PicoLED™ series.
