Equivalent & Substitute Parts for MV8331 Yellow LED T-1 3/4 Through Hole

Part Overview

The MV8331 is an active yellow LED indicator manufactured by Everlight Electronics Co Ltd, designed for discrete indication applications in through-hole mounting configurations. This T-1 3/4 form factor LED features a clear, domed lens and operates at a forward voltage of 2.1V with a test current of 20mA. The component is ROHS3 compliant and maintains unlimited moisture sensitivity rating (MSL 1), making it suitable for standard industrial and commercial applications. Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable or when inventory requirements necessitate component alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MV8331 are identified based on strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Color: Yellow (visual function requirement)
• Lens Transparency: Clear (optical performance)
• Mounting Type: Through Hole (assembly compatibility)
• Package / Case: Radial (lead configuration)
• RoHS Status: ROHS3 Compliant (regulatory compliance)

Allowable Parameter Variations:

• Lens Size: Minor dimensional variations within standard T-1 3/4 and 5mm specifications are acceptable provided mechanical fit is maintained
• Voltage - Forward (Vf): Variations within ±0.2V are permissible when circuit design includes appropriate current-limiting resistors
• Millicandela Rating: Variations in brightness are acceptable if application requirements do not specify exact luminous intensity
• Viewing Angle: Variations are acceptable based on application field-of-view requirements
• Wavelength - Peak: Minor shifts within yellow spectrum range (580-595nm) are acceptable for indication applications

The substitute part 5219466F from Dialight meets all mandatory matching criteria and falls within allowable variation ranges for secondary parameters.

Parameter Comparison

Engineering Selection Recommendations

The 5219466F from Dialight is a valid substitute for the MV8331 based on the following engineering criteria:

Regulatory and Compliance Alignment: Both components maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with standard industrial and commercial application requirements.

Electrical Compatibility: The forward voltage difference of 0.1V (2.1V vs 2.2V) is within acceptable tolerance for circuits designed with standard current-limiting resistor networks. Both components operate at the same 20mA test current specification.

Mechanical and Optical Compatibility: Both components feature identical through-hole radial package configurations with round domed-top clear lenses. Physical dimensions are compatible, with height variation of 0.08mm being negligible for standard PCB assembly.

Application-Dependent Considerations: The 5219466F exhibits lower millicandela rating (140mcd vs 630mcd) and narrower viewing angle (24° vs 30°). Selection between these components depends on specific application requirements for brightness and field-of-view. For applications requiring the full brightness and viewing angle specifications of the MV8331, the substitute may not be suitable. For standard indication applications with less stringent brightness requirements, the 5219466F provides equivalent functionality.

Frequently Asked Questions (FAQ)

Q: Can the 5219466F directly replace the MV8331 in all applications?

A: The 5219466F is mechanically and electrically compatible for through-hole PCB assembly. However, the substitute exhibits lower brightness (140mcd vs 630mcd) and narrower viewing angle (24° vs 30°). Applications requiring the full brightness and viewing specifications of the MV8331 should not use this substitute. Standard indication applications with less stringent optical requirements can use the 5219466F.

Q: What is the significance of the 0.1V forward voltage difference?

A: The forward voltage difference of 0.1V between the MV8331 (2.1V) and 5219466F (2.2V) is within standard circuit design tolerance. Circuits using current-limiting resistors will accommodate this variation without performance degradation. No circuit redesign is required for substitution.

Q: Are both components RoHS compliant?

A: Yes, both the MV8331 and 5219466F are ROHS3 compliant and maintain unlimited moisture sensitivity rating (MSL 1), meeting standard regulatory requirements for industrial and commercial applications.

Q: What are the physical dimension differences?

A: The MV8331 has a maximum height of 8.89mm, while the 5219466F has a maximum height of 8.81mm. The lens diameter of the 5219466F is specified as 4.83mm compared to the standard 5mm T-1 3/4 specification. These variations are within acceptable mechanical tolerance for standard through-hole PCB assembly.

Q: How do the optical specifications compare?

A: The MV8331 provides 630mcd brightness with a 30° viewing angle, while the 5219466F provides 140mcd with a 24° viewing angle. Both operate in the yellow spectrum (590nm vs 583nm peak wavelength). The choice between components depends on application requirements for brightness and field-of-view coverage.

Q: What packaging formats are available?

A: The MV8331 is supplied in standard packaging format. The 5219466F is supplied in bulk packaging. Both are through-hole radial configuration components suitable for standard PCB assembly processes.
