Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MV6353 are categorized based on alignment with critical and important parameters. Substitution logic follows these criteria:

Parametric Equivalents maintain identical or near-identical electrical and optical characteristics across all critical parameters: yellow color, diffused lens transparency, 5mm T-1 3/4 form factor, through-hole mounting, and comparable forward voltage (2.0V to 2.2V range), current rating (20mA), and brightness (12mcd to 20mcd range).

Similar Parts share the same mounting type and general form factor but deviate in one or more important parameters such as lens transparency (clear vs. diffused), brightness rating, viewing angle, or forward voltage. These parts require circuit design verification before substitution.

Color Variants (such as 5219327F - green) differ fundamentally in color specification and are listed only for reference in applications where color flexibility exists.

The following parameters determine substitution eligibility:

• Color (Yellow required for direct substitution)
• Lens Transparency (Diffused preferred for equivalent performance)
• Lens Size (5mm T-1 3/4 for mechanical compatibility)
• Mounting Type (Through Hole required)
• Forward Voltage Range (1.9V to 2.2V acceptable with circuit adjustment)
• Brightness Range (1.8mcd to 140mcd depending on application requirements)

Parameter Comparison

Engineering Selection Recommendations

MV5353 (onsemi) - Parametric Equivalent

The MV5353 provides direct electrical and optical equivalence to the MV6353 with identical forward voltage (2.1V), test current (20mA), brightness (15mcd), viewing angle (65°), and physical dimensions (5mm T-1 3/4, 8.89mm height). Both components feature diffused yellow lenses and through-hole radial mounting. However, the MV5353 carries obsolete product status, indicating limited future availability. This part is suitable for replacement applications where existing inventory exists but not recommended for new designs requiring long-term supply assurance.

4308H7 (Visual Communications Company - VCC) - Similar Part with Optical Differences

The 4308H7 maintains mechanical compatibility (5mm T-1 3/4 through-hole mounting) and operates within acceptable forward voltage range (2.2V vs. 2.1V). However, this part features a clear lens rather than diffused, resulting in significantly higher brightness (140mcd vs. 15mcd) and narrower viewing angle (24° vs. 65°). The 4308H7 is suitable for applications requiring higher intensity indication or focused beam characteristics. Circuit design remains compatible due to similar forward voltage and current rating. RoHS3 compliance and active product status support long-term availability.

5219321F (Dialight Series 521) - Similar Part with Reduced Brightness and Current

The 5219321F shares yellow diffused lens characteristics and through-hole mounting but operates at reduced forward voltage (1.9V), significantly lower test current (2mA vs. 20mA), and substantially lower brightness (1.8mcd vs. 15mcd). The lens size is slightly smaller (4.83mm vs. 5mm nominal). This part is suitable for low-power indicator applications or designs with strict current budget constraints. Circuit design modification is required to accommodate the 2mA operating point. Viewing angle (50°) is narrower than the MV6353 (65°).

5219322F (Dialight Series 521) - Similar Part with Different Form Factor and Voltage

The 5219322F features a 3mm lens diameter (significantly smaller than 5mm), operates at substantially higher forward voltage (7.5V vs. 2.1V), and reduced test current (10mA vs. 20mA). Brightness (12.6mcd) is comparable to the MV6353. This part requires significant circuit redesign due to voltage incompatibility and is suitable only for applications where 3mm form factor and 7.5V operating point are acceptable. Mechanical fit in existing 5mm mounting holes is not compatible.

5219327F (Dialight Series 521) - Color Variant Reference Only

The 5219327F is a green LED with identical electrical characteristics to the 5219321F (1.8V, 2mA, 1.8mcd). This part is listed for reference only and is not a direct substitute for yellow indication applications. Use only in applications where green color indication is functionally acceptable.

Frequently Asked Questions (FAQ)

Q: Can the MV5353 directly replace the MV6353 in existing designs?

A: Yes, the MV5353 provides direct parametric equivalence with identical forward voltage (2.1V), test current (20mA), brightness (15mcd), viewing angle (65°), and physical dimensions. However, the MV5353 is obsolete, limiting future availability. For new designs, the MV6353 is preferred.

Q: Is the 4308H7 a suitable substitute if brightness is not critical?

A: The 4308H7 is mechanically compatible (5mm T-1 3/4 through-hole) and electrically compatible (2.2V forward voltage, 20mA current). However, the clear lens produces 140mcd brightness versus 15mcd for the MV6353, and the viewing angle is narrower (24° vs. 65°). Substitution is acceptable only if the application tolerates higher brightness and narrower beam angle.

Q: Why is the 5219322F not recommended as a direct substitute?

A: The 5219322F operates at 7.5V forward voltage compared to 2.1V for the MV6353, requiring complete circuit redesign. Additionally, the 3mm lens diameter is incompatible with 5mm mounting holes. This part is suitable only for new designs specifically requiring 3mm form factor and 7.5V operation.

Q: Can the 5219321F be used in applications requiring 15mcd brightness?

A: No. The 5219321F produces only 1.8mcd brightness, approximately 8% of the MV6353 output. This part is suitable only for low-intensity indicator applications. Circuit design must also accommodate 2mA test current instead of 20mA.

Q: What are the mechanical compatibility requirements for substitution?

A: Direct mechanical compatibility requires through-hole radial mounting and 5mm lens diameter (T-1 3/4 form factor). The 5219321F and 5219327F use 4.83mm diameter lenses, which may fit standard 5mm holes with slight clearance but are not precision-matched. The 5219322F uses 3mm diameter and is not mechanically compatible with 5mm mounting holes.

Q: Are all substitute parts RoHS3 compliant?

A: The MV6353, 4308H7, 5219321F, 5219322F, and 5219327F are all RoHS3 compliant. The MV5353 RoHS status is not specified in available documentation.

Q: What is the impact of viewing angle differences on substitution?

A: The MV6353 provides 65° viewing angle, suitable for wide-area indication. The 4308H7 (24°) provides focused indication, and the 5219321F (50°) provides intermediate coverage. Substitution with narrower viewing angle parts may reduce visibility in applications requiring wide-angle indication.

Q: Can forward voltage differences affect circuit design?

A: Yes. The MV6353 operates at 2.1V. The 4308H7 (2.2V) and 5219321F (1.9V) are within acceptable tolerance for most series-resistor designs. The 5219322F (7.5V) requires complete circuit redesign and is not compatible with existing 2.1V designs without modification.
