MV64520 Equivalent & Substitute Parts Reference

Part Overview

The MV64520 is a green LED indicator manufactured by Everlight Electronics Co Ltd, designed for through-hole mounting applications. This T-1 3/4 (5mm) radial LED operates at a forward voltage of 2.2V with a test current of 20mA, delivering 25 millicandela of luminous intensity with a clear lens and 35° viewing angle. The component is currently in active production status and maintains full ROHS3 compliance with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are necessary when the MV64520 reaches end-of-life status, when inventory constraints occur, or when design requirements necessitate alternative electrical characteristics such as different forward voltages or luminous intensity ratings.

Substitute Part Grouping Explanation

Substitute parts for the MV64520 are classified into two categories based on parametric alignment:

Parametric Equivalent (Full Compatibility): The MV5452 manufactured by onsemi matches all critical electrical and mechanical parameters of the MV64520: identical forward voltage (2.2V), test current (20mA), millicandela rating (25mcd), viewing angle (35°), peak wavelength (562nm), lens transparency (clear), lens size (T-1 3/4), and mounting type (through hole). The primary distinction is product status: MV5452 is classified as obsolete, whereas MV64520 remains active. Both components share identical height specifications (8.89mm maximum) and radial package configuration.

Similar Parts (Conditional Compatibility): The 4302H5-5V and 4302H5-12V manufactured by Visual Communications Company (VCC) share the same physical form factor (T-1 3/4 radial, through-hole mounting) and green color specification. However, these parts differ in three critical electrical parameters:

Lens Transparency: Diffused (versus clear on MV64520)
Millicandela Rating: 8mcd (versus 25mcd on MV64520)
Viewing Angle: 60° (versus 35° on MV64520)
Height: 10.08mm maximum (versus 8.89mm on MV64520)

The 4302H5-5V operates at 5V forward voltage with 12mA test current. The 4302H5-12V operates at 12V forward voltage with 13mA test current. These parts are suitable only when circuit design accommodates the specified voltage and current requirements, and when the reduced luminous intensity and wider viewing angle are acceptable for the application.

Engineering Selection Recommendations

For Direct Replacement (Electrical and Mechanical Equivalence):

The MV5452 from onsemi provides complete parametric equivalence to the MV64520. Both components operate identically across all specified electrical parameters (2.2V forward voltage, 20mA test current, 25mcd luminous intensity, 35° viewing angle, 562nm peak wavelength) and share identical mechanical specifications (T-1 3/4 form factor, 8.89mm maximum height, radial through-hole mounting). The MV5452 is suitable for direct substitution in existing circuit designs without modification to current-limiting resistor values or circuit topology. However, the MV5452 carries obsolete product status, indicating limited future availability. Both components maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

For Conditional Substitution (Voltage-Specific Applications):

The 4302H5-5V and 4302H5-12V from VCC are suitable substitutes only when the circuit design specifically requires the stated forward voltage (5V or 12V respectively) and can accommodate the reduced luminous intensity (8mcd versus 25mcd) and wider viewing angle (60° versus 35°). These parts are active products with ROHS3 compliance and unlimited MSL rating. The 4302H5-5V operates at 12mA test current; the 4302H5-12V operates at 13mA test current. Both feature diffused lens transparency, which produces a broader light distribution compared to the clear lens of the MV64520. The increased maximum height (10.08mm versus 8.89mm) must be verified against PCB layout constraints and mechanical clearance requirements.

Frequently Asked Questions (FAQ)

Q: Can the MV5452 replace the MV64520 without circuit modification?

A: Yes. The MV5452 is a parametric equivalent with identical forward voltage (2.2V), test current (20mA), luminous intensity (25mcd), viewing angle (35°), and mechanical form factor (T-1 3/4 radial, 8.89mm height). No changes to current-limiting resistor values or circuit topology are required. The primary consideration is product status: MV5452 is obsolete, whereas MV64520 is active.

Q: What are the key differences between the MV64520 and the 4302H5-5V?

A: The 4302H5-5V differs in four critical parameters: forward voltage (5V versus 2.2V), test current (12mA versus 20mA), luminous intensity (8mcd versus 25mcd), lens transparency (diffused versus clear), viewing angle (60° versus 35°), and maximum height (10.08mm versus 8.89mm). Substitution requires circuit redesign to accommodate the 5V forward voltage and acceptance of reduced brightness and wider light distribution.

Q: Can the 4302H5-12V be used in a circuit designed for the MV64520?

A: No, not without circuit modification. The 4302H5-12V operates at 12V forward voltage, compared to 2.2V for the MV64520. Direct substitution would result in incorrect LED operation or component failure. The circuit must be redesigned to accommodate the 12V forward voltage and 13mA test current. Additionally, the reduced luminous intensity (8mcd versus 25mcd) and diffused lens transparency will alter the visual appearance and brightness of the indicator.

Q: Are all substitute parts ROHS3 compliant?

A: The MV64520, 4302H5-5V, and 4302H5-12V are confirmed ROHS3 compliant. The MV5452 compliance status is not specified in the provided data.

Q: What is the impact of lens transparency differences?

A: The MV64520 features a clear lens, which produces a focused, bright point of light with a 35° viewing angle. The 4302H5-5V and 4302H5-12V feature diffused lenses, which scatter light over a wider 60° viewing angle but reduce peak brightness. Clear lenses are suitable for applications requiring high brightness and directional indication; diffused lenses are suitable for applications requiring broad visibility from multiple angles.

Q: Do all parts have the same moisture sensitivity rating?

A: The MV64520, MV5452, 4302H5-5V, and 4302H5-12V all carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints during storage or handling.

Q: What is the significance of the 0.19mm height difference between MV64520 and the VCC parts?

A: The MV64520 has a maximum height of 8.89mm, while the 4302H5-5V and 4302H5-12V have a maximum height of 10.08mm. This 1.19mm difference must be verified against PCB layout constraints, component clearance requirements, and mechanical enclosure specifications. In applications with tight vertical space limitations, this difference may prevent substitution.
