MV3450 Equivalent & Substitute Parts Reference

Part Overview

The MV3450 is a green LED indicator manufactured by Everlight Electronics Co Ltd, designed for through-hole applications in T-1 3/4 (5mm) form factor. This component operates at 2.2V forward voltage with 150mcd brightness and features a clear lens for direct light emission. The part is currently in active production status with 937 units in stock.

Substitute parts become necessary when the primary MV3450 is unavailable, when alternative manufacturers are required for supply chain diversification, or when application-specific requirements demand different electrical characteristics such as voltage rating or brightness level.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MV3450 are classified into two categories based on electrical and optical compatibility:

Parametric Equivalents share identical or near-identical electrical and optical characteristics:

• Forward voltage (Vf): 2.2V
• Test current: 20mA
• Millicandela rating: 150mcd
• Lens transparency: Clear
• Viewing angle: 24°
• Wavelength peak: 565nm
• Physical form factor: T-1 3/4 (5mm) through-hole radial

Similar Parts maintain the same physical form factor and color but differ in one or more electrical parameters (voltage rating, brightness, lens transparency, or viewing angle). These parts are suitable only when application requirements permit deviation from the original specifications.

The following parameters are critical for determining substitutability:

• Lens size and form factor (T-1 3/4 / 5mm)
• Mounting type (through-hole radial)
• Color (green)
• Forward voltage rating
• Brightness (millicandela)
• Lens transparency (clear vs. diffused)

Parameter Comparison

Engineering Selection Recommendations

Direct Parametric Equivalents (Recommended for Direct Substitution):

HLMP-C523 (Broadcom Limited) is the preferred parametric equivalent. It maintains identical forward voltage (2.2V), test current (20mA), clear lens transparency, and comparable brightness (170mcd vs. 150mcd). The part is in active production status with ROHS3 compliance. Inventory availability is 5,850 units.

MV3450B4R0 (Fairchild Semiconductor) provides identical electrical and optical specifications to the MV3450. This part is in active production status with 63,566 units in stock, offering superior availability. RoHS status is not applicable; verify compliance requirements for your application.

HLMP3950A (Fairchild Semiconductor) matches all critical parameters but carries obsolete product status. Use only when no active alternatives are available and long-term supply is not required.

Conditional Substitutes (Application-Dependent):

HLMP-3507 (Broadcom Limited) differs significantly in brightness (4.2mcd vs. 150mcd), viewing angle (60° vs. 24°), and lens transparency (diffused vs. clear). Suitable only for applications where reduced brightness and wider viewing angle are acceptable.

4302H5-5V and 4302H5-12V (Visual Communications Company - VCC) are diffused-lens variants with substantially lower brightness (8mcd) and higher voltage ratings (5V and 12V respectively). These parts are suitable only for applications with different voltage supply requirements and where reduced brightness is acceptable.

Frequently Asked Questions (FAQ)

Q: Can HLMP-C523 replace MV3450 in all applications?

A: HLMP-C523 is a parametric equivalent with identical forward voltage (2.2V), test current (20mA), and clear lens transparency. The brightness difference (170mcd vs. 150mcd) and viewing angle (25° vs. 24°) are within typical manufacturing tolerances. Substitution is valid for applications where these minor variations are acceptable. Verify circuit design does not depend on exact brightness specifications.

Q: What is the difference between clear and diffused lens options?

A: Clear lens LEDs (MV3450, HLMP-C523, HLMP3950A) emit concentrated light in a narrow viewing angle (24-25°), suitable for direct indication. Diffused lens LEDs (HLMP-3507, 4302H5 series) scatter light across a wider viewing angle (60°), suitable for applications requiring visibility from multiple angles. These are not interchangeable without circuit redesign.

Q: Why do 4302H5-5V and 4302H5-12V have different voltage ratings?

A: These parts are designed for different supply voltage systems. The 4302H5-5V operates at 5V forward voltage with 12mA test current, while 4302H5-12V operates at 12V with 13mA test current. Selection depends on your circuit's power supply voltage. Direct substitution requires matching the voltage rating to your application.

Q: Is MV3450B4R0 suitable for RoHS-compliant applications?

A: MV3450B4R0 carries "Not applicable" RoHS status. Verify with your compliance requirements and the manufacturer before using in applications requiring explicit ROHS3 certification. HLMP-C523 and HLMP-3507 are confirmed ROHS3 compliant alternatives.

Q: What does "obsolete" product status mean for HLMP3950A?

A: Obsolete status indicates the manufacturer has discontinued production. While 19,308 units are currently in stock, long-term availability cannot be guaranteed. Use HLMP3950A only when active alternatives are exhausted or for short-term requirements. Prefer active-status parts (HLMP-C523, MV3450B4R0) for new designs.

Q: Can I use HLMP-3507 as a direct replacement?

A: HLMP-3507 shares the same physical form factor and green color but differs in multiple electrical parameters: forward voltage (2.1V vs. 2.2V), test current (10mA vs. 20mA), brightness (4.2mcd vs. 150mcd), viewing angle (60° vs. 24°), and lens transparency (diffused vs. clear). This part is suitable only when application requirements explicitly permit these deviations. Circuit redesign may be necessary.

Q: Are all substitute parts available in the same packaging?

A: All listed parts use T-1 3/4 (5mm) through-hole radial packaging. Physical dimensions vary slightly: MV3450 height is 8.89mm, HLMP-C523 is 8.91mm, HLMP-3507 is 9.19mm, and 4302H5 series is 10.08mm. Verify PCB hole spacing and component clearance before substitution.
