MV8411 Equivalent & Substitute Parts

Part Overview

The onsemi MV8411 is a green LED indicator in T-1 3/4 through-hole radial package, rated at 2.1V forward voltage with 370mcd brightness. This part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The MV8411 provides green indication in discrete LED applications requiring clear lens optics and standard configuration mounting.

Substitute Part Grouping Explanation

Substitution eligibility for the MV8411 is determined by the following critical parameters:

Color: Green (all substitutes must be green)
Lens Transparency: Clear (optical clarity requirement)
Mounting Type: Through Hole radial configuration
Lens Size: 5mm, T-1 3/4 form factor
Wavelength - Peak: 565nm (green spectrum alignment)
Package / Case: Radial

Substitutes are grouped into two categories based on forward voltage compatibility:

Category A - Direct Voltage Substitutes (2.1V to 3.2V range): Parts with forward voltages within the operational envelope of the original design, allowing direct circuit substitution with minimal or no resistor adjustment.

Category B - Voltage-Adapted Substitutes (5V to 12V): Parts requiring series resistor recalculation due to higher forward voltage ratings. These are suitable only when circuit design permits resistor modification.

Engineering Selection Recommendations

Primary Substitutes (Direct Replacement - Minimal Circuit Modification)

The Dialight 5219465F is the closest electrical equivalent, with forward voltage of 2.3V compared to the MV8411's 2.1V. Both operate at 20mA test current and share identical wavelength characteristics at 565nm. Physical dimensions are nearly identical (8.81mm vs 8.89mm height). The 5219465F is active product status with RoHS3 compliance, providing long-term availability assurance.

Secondary Substitutes (Voltage-Compatible Range - Minor Resistor Adjustment)

The Broadcom HLMP-CM series parts (HLMP-CM1G-350DD, HLMP-CM1A-560DD, HLMP-CM2A-230DD, HLMP-CM3A-Z10DD, HLMP-CM3A-Z1CDD, HLMP-CM3B-Z10DD, HLMP-CM3G-Y10DD) operate at 3.1V to 3.2V forward voltage. These require series resistor recalculation due to the 1.0V to 1.1V voltage differential. All Broadcom parts maintain 20mA test current, 5mm T-1 3/4 form factor, and active product status with RoHS3 compliance. Height specifications range from 8.90mm to 12.25mm, with the HLMP-CM3B-Z10DD exceeding original dimensions.

Alternative Substitutes (Voltage-Adapted - Significant Circuit Modification Required)

The VCC 4302H5-5V and 4302H5-12V parts feature diffused lens transparency rather than clear, and operate at 5V and 12V respectively. These require substantial series resistor redesign and are suitable only when optical diffusion is acceptable and circuit topology permits voltage adaptation. Both maintain active product status and RoHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can the Dialight 5219465F directly replace the MV8411 without circuit modification?

A: The 5219465F is electrically compatible with minimal adjustment. The 0.2V forward voltage difference (2.3V vs 2.1V) is within typical circuit tolerance for LED indicator applications. Verify existing series resistor value accommodates this variance; most designs will function without modification.

Q: What is the primary difference between Broadcom HLMP-CM1, HLMP-CM2, and HLMP-CM3 series?

A: The series differ in millicandela rating and viewing angle. HLMP-CM1 provides 60500mcd at 15° viewing angle. HLMP-CM2 provides 28000mcd at 23° viewing angle. HLMP-CM3 provides 16500mcd at 30° viewing angle. All operate at 3.1V to 3.2V forward voltage and 20mA test current.

Q: Why do VCC 4302H5 parts have diffused lenses instead of clear?

A: The 4302H5 series is designed for applications requiring light diffusion. Diffused lenses scatter light over a wider viewing angle (60° vs 12-30°) but reduce peak brightness. These are suitable only when optical diffusion meets application requirements.

Q: What is the impact of the 1.1V forward voltage increase when using Broadcom HLMP-CM parts?

A: The higher forward voltage requires series resistor recalculation to maintain 20mA test current. For a given supply voltage, the resistor value must increase proportionally. Consult circuit design specifications and perform resistor calculations before implementation.

Q: Are all substitute parts RoHS3 compliant?

A: All active substitute parts listed are RoHS3 compliant. The MV8411 is obsolete and does not carry RoHS certification. Broadcom and VCC parts provide long-term compliance assurance for new designs and production runs.

Q: Can HLMP-CM3B-Z10DD be used in space-constrained applications?

A: The HLMP-CM3B-Z10DD has a maximum height of 12.25mm, exceeding the MV8411's 8.89mm specification. This part is unsuitable for applications with height restrictions. Use HLMP-CM3A-Z10DD (8.90mm) or HLMP-CM3G-Y10DD (8.90mm) for space-constrained designs.

Q: What wavelength differences exist between MV8411 and Broadcom substitutes?

A: The MV8411 operates at 565nm peak wavelength. Broadcom HLMP-CM parts operate at 516-517nm peak wavelength, representing a shift toward shorter wavelengths within the green spectrum. Both wavelengths are within standard green LED specifications and visually indistinguishable in most applications.
