MV5374C Equivalent & Substitute Parts

Part Overview

The MV5374C is a yellow diffused LED indicator manufactured by Everlight Electronics Co Ltd, designed for through-hole mounting applications. This T-1 (3mm) radial LED operates at 2.1V forward voltage with a 9mcd brightness rating and 90° viewing angle. The component is classified as Active product status and is RoHS3 compliant.

Substitute parts are necessary when the primary component becomes unavailable, when design requirements demand alternative brightness levels or viewing angles, or when sourcing from alternative manufacturers is required for supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MV5374C is determined by the following critical parameters:

Primary Compatibility Criteria:

• Color: Yellow
• Lens Transparency: Diffused
• Mounting Type: Through Hole
• Package Type: Radial, T-1 (3mm)
• Voltage - Forward (Vf): 2.1V (±0.1V tolerance acceptable)
• Wavelength Range: 585nm–590nm (yellow spectrum)

Secondary Compatibility Criteria:

• Millicandela Rating: 3mcd–15mcd (brightness variation acceptable based on application requirements)
• Viewing Angle: 60°–100° (application-dependent)
• Current - Test: 10mA–20mA (design-dependent)
• Height (Max): 4.60mm–6.00mm (PCB clearance-dependent)

Parts meeting all primary criteria are classified as direct substitutes. Parts meeting primary criteria with variations in secondary parameters are classified as functional equivalents with noted trade-offs.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Preferred):

SLR-332YY3F (Rohm Semiconductor) meets all primary compatibility criteria with identical forward voltage (2.1V) and yellow diffused lens specification. This part is Active product status and RoHS3 compliant. The 10mA test current and 6.3mcd brightness represent lower power consumption and reduced brightness compared to the main part. The 85° viewing angle is marginally narrower than the 90° specification. Height of 4.60mm provides additional PCB clearance margin. This substitute is suitable for applications where reduced brightness and lower current draw are acceptable.

WP3A10YD (Kingbright) meets all primary compatibility criteria with identical forward voltage (2.1V), 3mm T-1 lens size, and yellow diffused specification. This part is Active product status and RoHS3 compliant. The 20mA test current matches the main part specification. The 15mcd brightness rating exceeds the main part by 67%, providing enhanced visibility. The 60° viewing angle is narrower, concentrating light output in a more focused beam. Height of 5.00mm is within acceptable range. This substitute is suitable for applications requiring increased brightness with directional light output.

WP424YDT (Kingbright) meets all primary compatibility criteria with identical forward voltage (2.1V) and yellow diffused lens specification. This part is Active product status and RoHS3 compliant. The 20mA test current matches the main part. The 3mcd brightness rating is significantly lower (67% reduction), suitable for low-intensity indicator applications. The 100° viewing angle provides the widest light distribution. Height of 6.00mm is the maximum acceptable dimension. This substitute is suitable for applications requiring minimal brightness with wide viewing angle.

Secondary Substitute (Limited Compatibility):

SLR-332DU3F (Rohm Semiconductor) is an orange diffused LED with 605nm wavelength, differing from the yellow specification of the main part. This part is Not For New Designs product status, indicating discontinued or obsolete classification. While it shares T-1 through-hole radial package characteristics and RoHS3 compliance, the color mismatch disqualifies it as a functional equivalent for yellow indicator applications. This part should not be selected for new designs.

All substitute parts listed are RoHS3 compliant and suitable for applications requiring environmental compliance. Product status verification confirms that SLR-332YY3F, WP3A10YD, and WP424YDT are Active, supporting long-term availability and design continuity.

Frequently Asked Questions (FAQ)

Q: Can WP3A10YD replace MV5374C in all applications?

A: WP3A10YD is a direct substitute meeting all primary compatibility criteria. However, the 60° viewing angle is narrower than the 90° specification of MV5374C. Applications requiring wide-angle light distribution should evaluate this parameter against specific design requirements.

Q: What is the brightness difference between MV5374C and its substitutes?

A: MV5374C operates at 9mcd. SLR-332YY3F provides 6.3mcd (30% reduction), WP3A10YD provides 15mcd (67% increase), and WP424YDT provides 3mcd (67% reduction). Brightness selection depends on application visibility requirements and power budget constraints.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. MV5374C, SLR-332YY3F, WP3A10YD, and WP424YDT are all RoHS3 compliant. SLR-332DU3F is also RoHS3 compliant but is Not For New Designs and should not be selected.

Q: What is the difference between test current and operating current?

A: Test current (20mA for MV5374C, 10mA for SLR-332YY3F, 20mA for WP3A10YD and WP424YDT) is the standardized measurement condition for brightness rating. Actual operating current in circuit design may differ based on series resistor selection and supply voltage. Forward voltage (2.1V) remains constant across all yellow substitutes.

Q: Can I use WP424YDT if my application requires 9mcd brightness?

A: No. WP424YDT provides 3mcd brightness, which is insufficient for applications requiring 9mcd output. WP3A10YD at 15mcd or SLR-332YY3F at 6.3mcd are more appropriate selections depending on whether increased or slightly reduced brightness is acceptable.

Q: What is the significance of wavelength specifications?

A: Wavelength indicates the color spectrum. MV5374C peak wavelength is 585nm (yellow). Substitutes SLR-332YY3F (587nm dominant), WP3A10YD (588nm dominant, 590nm peak), and WP424YDT (588nm dominant, 590nm peak) all fall within the yellow spectrum range (585nm–590nm), ensuring color consistency across substitutions.

Q: Are there height restrictions for PCB mounting?

A: Yes. MV5374C maximum height is 5.83mm. Substitutes range from 4.60mm (SLR-332YY3F) to 6.00mm (WP424YDT). Applications with tight PCB clearance constraints should verify height compatibility. SLR-332YY3F provides the most clearance margin.

Q: Why is SLR-332DU3F listed as a substitute if it is orange?

A: SLR-332DU3F is listed in the provided substitute data but is not recommended for MV5374C replacement due to color mismatch (orange vs. yellow) and Not For New Designs product status. It should be excluded from component selection for new designs.

Q: What is the viewing angle impact on application design?

A: Viewing angle determines the cone of light distribution. MV5374C at 90° provides moderate light spread. WP3A10YD at 60° concentrates light in a narrower beam (higher intensity in direct viewing direction). WP424YDT at 100° provides the widest distribution (lower intensity per direction). Selection depends on indicator placement and observer position requirements.
