Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5219284F is determined by the following critical parameters:

Primary Substitution Criteria:

• Color: Yellow (all substitutes must be yellow)
• Lens Transparency: Diffused (optical diffusion characteristic)
• Mounting Type: Through Hole Radial (mechanical compatibility)
• Wavelength - Peak: 583nm nominal (yellow spectrum alignment)

Secondary Compatibility Parameters:

• Voltage - Forward (Vf): Acceptable range 1.8V to 10V (circuit design dependent)
• Current - Test: Acceptable range 2mA to 20mA (driver capability dependent)
• Millicandela Rating: 2.1mcd to 140mcd (brightness application dependent)
• Viewing Angle: 24° to 70° (optical coverage dependent)
• Height (Max): 8.60mm to 9.95mm (mechanical clearance dependent)

The following parts meet the primary substitution criteria and are listed as acceptable alternatives based on the provided substitute list for the 5219284F:

• MV5353 (onsemi) - Obsolete status
• MV6353 (onsemi) - Obsolete status
• WP7113YD5V (Kingbright) - Active status
• HLMP-4719 (Broadcom Limited) - Active status
• 4308H7 (Visual Communications Company - VCC) - Active status

Parameter Comparison

Engineering Selection Recommendations

Active Status Parts (Recommended for New Designs):

• HLMP-4719 (Broadcom Limited): Active product with ROHS3 compliance. Diffused lens matches optical characteristics. Forward voltage of 1.8V and test current of 2mA require circuit redesign from the 5219284F baseline. Brightness of 2.1mcd is significantly lower. Viewing angle of 50° is narrower than the original 60°.

• WP7113YD5V (Kingbright): Active product with ROHS3 compliance. Diffused lens matches optical characteristics. Forward voltage of 5V is intermediate between the original 10V and lower-voltage alternatives. Test current of 13mA and brightness of 22mcd provide moderate performance. Viewing angle of 30° is narrower than the original 60°.

• 4308H7 (Visual Communications Company - VCC): Active product with ROHS3 compliance. Clear lens differs from the diffused specification of the 5219284F. Forward voltage of 2.2V and test current of 20mA require circuit redesign. Brightness of 140mcd is significantly higher. Viewing angle of 24° is narrower than the original 60°.

Obsolete Status Parts (Not Recommended for New Designs):

• MV5353 (onsemi): Obsolete product. Diffused lens matches optical characteristics. Forward voltage of 2.1V and test current of 20mA require circuit redesign. Brightness of 15mcd and viewing angle of 65° are comparable to the original specifications.

• MV6353 (onsemi): Obsolete product. Diffused lens matches optical characteristics. Forward voltage of 2.1V and test current of 20mA require circuit redesign. Brightness of 15mcd and viewing angle of 65° are comparable to the original specifications.

All substitute parts maintain ROHS3 compliance and through-hole radial mounting compatibility. Circuit redesign is required for all substitutes due to significant differences in forward voltage and test current specifications.

Frequently Asked Questions (FAQ)

Q: Can I directly replace the 5219284F with any of these substitute parts without circuit modification?

A: No. All listed substitute parts have different forward voltage (Vf) specifications ranging from 1.8V to 10V compared to the original 5219284F at 10V. Circuit redesign is required to accommodate the different voltage and current requirements of each substitute.

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

A: Diffused lenses scatter light over a wider area with reduced intensity, while clear lenses provide more focused, directional light output. The 5219284F specifies a diffused lens. The 4308H7 substitute features a clear lens, which will produce different optical characteristics in the application.

Q: Are the T-1 3/4 package substitutes mechanically compatible with the 5mm package of the 5219284F?

A: Both T-1 3/4 and 5mm refer to through-hole radial LED packages with similar mechanical form factors. The height differences (8.60mm to 9.95mm maximum) are within typical PCB design tolerances. Verify mechanical clearance in your specific application before substitution.

Q: Why are MV5353 and MV6353 listed as substitutes if they are obsolete?

A: Obsolete parts are included in the substitute list for reference and legacy system support. For new designs, active status parts (HLMP-4719, WP7113YD5V, 4308H7) are recommended to ensure long-term supply chain availability and continued manufacturer support.

Q: What is the significance of the wavelength peak specification?

A: Wavelength peak (583nm to 590nm) defines the dominant color emission within the yellow spectrum. All listed substitutes emit in the yellow range. Minor wavelength variations may produce slight color perception differences but remain within the yellow LED category.

Q: How do brightness ratings (millicandela) affect substitution decisions?

A: Brightness ratings range from 2.1mcd (HLMP-4719) to 140mcd (4308H7). The 5219284F operates at 8mcd. Higher brightness substitutes may require optical diffusion or reduced drive current to match the original application brightness. Lower brightness substitutes may require increased drive current or optical concentration.

Q: What viewing angle considerations apply to these substitutes?

A: Viewing angle ranges from 24° (4308H7) to 70° (MV6351 reference). The 5219284F specifies 60°. Narrower viewing angles concentrate light output, while wider angles distribute it. Application requirements determine acceptable viewing angle ranges for visual indication purposes.
