QTLP630C2TR Red LED 0805 SMD Equivalent & Substitute Parts

Part Overview

The QTLP630C2TR is a red LED indicator manufactured by Everlight Electronics Co Ltd, designed for discrete indication applications in 0805 (2012 Metric) surface mount packages. This component operates at 2V forward voltage with a 630nm dominant wavelength and 10mcd brightness rating. The product is currently Active and widely available with 1051 pieces in stock.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit alternative specifications within acceptable electrical and mechanical tolerances. The SML-210VTT86 from Rohm Semiconductor is identified as a direct substitute option, though it carries a Not For New Designs status that must be evaluated against project requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QTLP630C2TR is determined by strict alignment of the following parameters:

Mandatory Matching Parameters:

• Package / Case: 0805 (2012 Metric)
• Voltage - Forward (Vf) (Typ): 2V
• Current - Test: 20mA
• Mounting Type: Surface Mount
• Color: Red
• Lens Transparency: Clear
• Size / Dimension: 2.00mm L x 1.25mm W
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 3 (168 Hours)

Variable Parameters Permitting Substitution:

• Millicandela Rating: Brightness may vary within application tolerance
• Wavelength - Dominant: Red spectrum variations acceptable for indication applications
• Wavelength - Peak: Peak wavelength may differ while maintaining red color specification
• Viewing Angle: May vary based on lens design
• Height (Max): Physical height variation within 0805 package envelope
• Lens Size: Lens dimensions may vary within package constraints
• Lens Style: Rectangle with Flat Top maintained across substitutes

The SML-210VTT86 meets all mandatory matching parameters and qualifies as a direct substitute based on electrical and mechanical compatibility.

Engineering Selection Recommendations

Primary Component Selection: The QTLP630C2TR is the recommended choice for new design implementations. It carries Active product status, ensuring long-term availability and manufacturer support. The component is ROHS3 compliant and maintains full compliance with current regulatory requirements. Current inventory of 1051 pieces supports immediate procurement needs.

Substitute Component Consideration: The SML-210VTT86 qualifies as an electrical and mechanical substitute based on matching package, voltage, current, and compliance specifications. However, the following factors must be evaluated:

• Product Status: SML-210VTT86 carries Not For New Designs designation, limiting its suitability for new product development
• Brightness Differential: SML-210VTT86 provides 4mcd versus QTLP630C2TR's 10mcd, representing a 60% reduction in brightness
• Physical Height: SML-210VTT86 maximum height of 0.90mm versus QTLP630C2TR's 1.20mm may provide advantages in space-constrained applications
• Wavelength Variation: Peak wavelength difference (650nm vs 635nm) remains within red spectrum for indication applications

Application-Specific Guidance: Use SML-210VTT86 only when QTLP630C2TR supply is unavailable and brightness reduction is acceptable for the intended indication function. Verify circuit design accommodates the lower luminous intensity. For new designs, maintain QTLP630C2TR as the primary component specification.

Frequently Asked Questions (FAQ)

Q: Can SML-210VTT86 be used as a direct drop-in replacement for QTLP630C2TR?

A: SML-210VTT86 is mechanically and electrically compatible for PCB assembly and circuit operation. Both components share identical package dimensions (2.00mm L x 1.25mm W), forward voltage (2V), and test current (20mA). However, the 60% brightness reduction (4mcd vs 10mcd) may affect visual indication performance depending on application requirements. Evaluate brightness adequacy before substitution.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Brightness - QTLP630C2TR provides 10mcd versus SML-210VTT86's 4mcd; (2) Physical height - SML-210VTT86 is 0.90mm maximum versus QTLP630C2TR's 1.20mm; (3) Peak wavelength - 635nm versus 650nm; (4) Product status - QTLP630C2TR is Active while SML-210VTT86 is Not For New Designs. All other electrical and mechanical parameters are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both QTLP630C2TR and SML-210VTT86 are ROHS3 compliant and meet current environmental regulations. Both components also share identical Moisture Sensitivity Level (MSL) rating of 3 (168 Hours), requiring equivalent storage and handling protocols.

Q: Which part should be specified for new product designs?

A: QTLP630C2TR is the specified component for new designs. It maintains Active product status, ensuring manufacturer support and long-term availability. SML-210VTT86's Not For New Designs status indicates Rohm Semiconductor is not recommending this component for new applications.

Q: Can the lower brightness of SML-210VTT86 affect circuit performance?

A: The 4mcd brightness of SML-210VTT86 is sufficient for indication applications where visual perception is the primary function. However, applications requiring high brightness visibility in bright ambient light conditions may experience reduced performance. Evaluate specific application lighting conditions and visibility requirements before substitution.

Q: Are the package dimensions truly identical?

A: Yes. Both components use 0805 (2012 Metric) packages with identical length (2.00mm) and width (1.25mm) dimensions. The maximum height differs (1.20mm vs 0.90mm), but both fit within standard 0805 package envelope specifications. PCB footprints are identical and interchangeable.

Q: What is the significance of the wavelength difference?

A: QTLP630C2TR has a dominant wavelength of 630nm with peak at 635nm, while SML-210VTT86 has peak wavelength of 650nm. Both wavelengths fall within the red spectrum and produce visually identical red indication. The wavelength difference does not affect functional compatibility for indication applications.
