SML-110PTT86 Equivalent & Substitute Parts

Part Overview

The SML-110PTT86 is a green LED indicator (560nm wavelength) manufactured by Rohm Semiconductor in a 1208 (3020 Metric) surface mount package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and production continuity. The part delivers 6.3mcd luminous intensity at 20mA test current with a forward voltage of 2.2V, suitable for standard indication applications requiring discrete LED solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SML-110PTT86 is determined by the following critical parameters:

• Color and Wavelength: Green 560nm wavelength must be maintained for optical compatibility
• Electrical Characteristics: Forward voltage (2.2V) and test current (20mA) define circuit compatibility
• Luminous Intensity: 6.3mcd rating establishes brightness performance requirements
• Mounting Type: Surface mount configuration required for PCB assembly compatibility
• Lens Properties: Colorless, clear lens maintains optical transmission characteristics
• Compliance: RoHS3 compliance and REACH unaffected status required for regulatory alignment

The substitute part SML-A12P8TT86 meets these core substitution criteria while differing in package form factor and mounting orientation.

Parameter Comparison

Engineering Selection Recommendations

The SML-A12P8TT86 serves as an active substitute for the obsolete SML-110PTT86. Both components maintain identical electrical performance (2.2V forward voltage, 20mA test current, 6.3mcd luminous intensity) and optical specifications (560nm green wavelength, colorless clear lens). Both achieve ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements.

The primary design consideration is the package form factor change: the substitute transitions from a standard 1208 (3020 Metric) package to a 1611 (0605) 2-SMD, No Lead configuration with right-angle mounting orientation. This requires PCB layout modification to accommodate the smaller footprint (1.60mm L x 1.15mm W versus 3.00mm L x 2.00mm W) and different mounting geometry. The substitute part is currently in active production status, ensuring long-term availability.

Frequently Asked Questions (FAQ)

Q: Can SML-A12P8TT86 directly replace SML-110PTT86 without circuit modification?

A: Electrical circuit compatibility is maintained (identical 2.2V forward voltage and 20mA test current). However, PCB layout modification is required due to package form factor differences and right-angle mounting orientation of the substitute.

Q: Are the optical characteristics identical between these parts?

A: Yes. Both components deliver 6.3mcd luminous intensity at 560nm dominant wavelength with colorless, clear lens properties. Optical performance is equivalent.

Q: What is the primary reason for substitution?

A: The SML-110PTT86 is classified as obsolete. The SML-A12P8TT86 is an active production part from the same manufacturer, ensuring supply continuity and long-term availability.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant and REACH unaffected, satisfying equivalent regulatory requirements.

Q: What are the key package differences?

A: The main part uses a 1208 (3020 Metric) standard surface mount package (3.00mm L x 2.00mm W x 2.20mm H). The substitute uses a smaller 1611 (0605) 2-SMD, No Lead package (1.60mm L x 1.15mm W x 0.65mm H) with right-angle mounting orientation.

Q: Is the substitute part readily available?

A: Yes. The SML-A12P8TT86 is in active production status with 20,986 pieces in stock, compared to the obsolete SML-110PTT86 with 874 pieces remaining.
