MV8303 Equivalent & Substitute Parts

Part Overview

The MV8303 is a yellow LED indication component manufactured by Everlight Electronics Co Ltd, designed for through-hole mounting applications. This T-1 3/4 radial LED operates at a forward voltage of 2.1V with a test current of 20mA and delivers 940 millicandela of luminous intensity. The component is classified as Active product status and maintains full ROHS3 compliance with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified to provide equivalent or enhanced performance characteristics for applications requiring yellow LED indication with comparable electrical and mechanical specifications. Alternatives are selected based on matching or exceeding critical parameters including forward voltage, test current, lens configuration, mounting type, and physical dimensions.

Substitute Part Grouping Explanation

Substitute parts are grouped into two categories based on substitution compatibility with the MV8303:

Category A: Direct Substitutes (Yellow LED, 2.0V-2.2V Forward Voltage)

These parts maintain the same color (yellow), similar forward voltage range (2.0V to 2.2V), identical test current (20mA), matching lens configuration (round domed top, clear), through-hole mounting, and T-1 3/4 or 5mm package format. Parts in this category are electrically and mechanically compatible with the MV8303 in standard indication applications.

Key matching parameters:

Color: Yellow
Forward Voltage (Vf): 2.0V to 2.2V
Test Current: 20mA
Lens Style: Round with Domed Top
Lens Transparency: Clear
Mounting Type: Through Hole
Package: T-1 3/4 or 5mm equivalent
RoHS3 Compliance: Required

Category B: Functional Alternatives (Different Color - Orange LED)

These parts differ in color (orange instead of yellow) and operate at lower forward voltages (1.9V to 1.98V). These components are not direct substitutes but serve as functional alternatives when color-specific requirements do not apply. They maintain identical mounting type, lens configuration, and package format.

Frequently Asked Questions (FAQ)

Q: Can I use an orange LED substitute in place of the MV8303 yellow LED?

A: Orange LED substitutes (SLI-570DT3F, HLMP-EJ30-NR0DD) are mechanically and electrically compatible with the MV8303 but differ in color output. Use orange alternatives only when color-specific indication is not required by the application specification.

Q: What is the significance of forward voltage (Vf) matching?

A: Forward voltage determines the voltage drop across the LED during operation. The MV8303 operates at 2.1V. Substitutes with forward voltages between 2.0V and 2.2V are compatible with standard circuit designs. Orange alternatives operate at 1.9V to 1.98V and require circuit verification to ensure adequate current limiting.

Q: How does viewing angle affect LED selection?

A: Viewing angle determines the cone of light emission. The MV8303 has a 20° viewing angle. Substitutes with wider angles (30°, 45°) provide broader visibility but may appear dimmer at off-axis positions. Narrower angles concentrate light intensity in a specific direction. Select based on application visibility requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance consistent with the MV8303, meeting regulatory requirements for hazardous substance restrictions.

Q: What is the difference between T-1 3/4 and 5mm package designations?

A: T-1 3/4 and 5mm refer to the same physical package size (5mm diameter lens). Both designations describe through-hole radial LEDs with identical mechanical compatibility. Terminology varies by manufacturer convention.

Q: Can I substitute a higher millicandela LED for the MV8303?

A: Yes. Higher millicandela ratings (brightness) are acceptable substitutes provided all other parameters match (color, forward voltage, test current, mounting type, package format). Verify that increased brightness does not create glare or exceed application requirements.

Q: What does MSL 1 (Unlimited) mean?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All listed substitutes maintain this rating, ensuring equivalent storage and handling requirements.

Q: Are there inventory considerations for substitute selection?

A: Inventory availability varies by substitute part. OVLGY0C9B9 (79595 units), OVLFY3C7 (41918 units), and LTL2R3KSK (15591 units) offer highest availability. Verify supplier stock status for production requirements.

Q: How do I verify electrical compatibility in my circuit?

A: Confirm that your current-limiting resistor is designed for the substitute part's forward voltage. For parts with forward voltage within 0.1V of the MV8303 (2.0V to 2.2V), existing resistor values remain valid. Orange alternatives at 1.9V require circuit recalculation.
