MV8303 Yellow LED T-1 3/4 Through Hole - Equivalent & Substitute Parts

Part Overview

The onsemi MV8303 is a yellow LED indication component in T-1 3/4 (5mm) through-hole radial package, rated at 2.1V forward voltage with 940mcd brightness. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. Substitute parts must maintain compatibility across electrical characteristics, mechanical form factor, and mounting requirements while meeting current product availability and compliance standards.

Substitute Part Grouping Explanation

Substitution logic for the MV8303 is based on the following critical parameters:

Color Match: Yellow LED indication function
Package Compatibility: T-1 3/4 (5mm) through-hole radial form factor
Electrical Compatibility: Forward voltage within acceptable range (1.9V to 2.2V at 20mA test current)
Mechanical Fit: Height and lens dimensions compatible with PCB layout
Optical Performance: Wavelength in the yellow spectrum (583nm to 592nm peak wavelength)
Regulatory Compliance: REACH and RoHS status for current procurement

Substitute parts are grouped into two categories:

Category 1 - Direct Yellow LED Substitutes: Parts maintaining yellow color, similar forward voltage (2.1V to 2.2V), and T-1 3/4 package form factor.

Category 2 - Alternative Color Substitutes: Amber and orange LED parts with compatible electrical and mechanical parameters. These are functional alternatives where color shift is acceptable in the application.

Engineering Selection Recommendations

Primary Substitutes (Yellow LED, Active Status)

The Würth Elektronik 151053YS04500 and Dialight 5219466F are direct functional replacements for the MV8303. Both maintain yellow color indication, T-1 3/4 through-hole radial package compatibility, and forward voltage within the acceptable operating range. Both parts are active products with ROHS3 compliance, ensuring long-term procurement availability and regulatory alignment.

The 151053YS04500 offers higher brightness (1500mcd vs. 940mcd) with a wider viewing angle (45° vs. 20°), suitable for applications requiring increased visibility. The 5219466F provides lower brightness (140mcd) with a narrower viewing angle (24°), appropriate for applications with tighter brightness constraints.

Alternative Substitutes (Amber/Orange LED, Active Status)

Broadcom Limited amber and orange LED parts (HLMP series) provide functional alternatives where color shift is acceptable. All Broadcom parts maintain T-1 3/4 package compatibility and forward voltage within 1.9V to 1.98V, requiring minimal circuit redesign. All listed Broadcom parts are active products with ROHS3 compliance.

Amber parts (HLMP-C225-O0000, HLMP-C225-O00DD) operate at 1.9V with 800mcd brightness and 25° viewing angle. Orange parts vary in brightness (1690mcd to 18150mcd) and viewing angle (8° to 15°), providing options for specific optical requirements.

Compliance Consideration

All substitute parts listed carry ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic component procurement. The MV8303 product status as obsolete necessitates transition to active alternatives for new designs and ongoing production support.

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 151053YS04500 directly replace the MV8303 without circuit modification?

A: Yes. Both parts operate at 2.1V forward voltage with 20mA test current and maintain identical T-1 3/4 through-hole radial package form factor. The 151053YS04500 provides higher brightness (1500mcd vs. 940mcd) and wider viewing angle (45° vs. 20°), which are compatible with the MV8303 application space without requiring circuit changes.

Q: What is the key difference between the Dialight 5219466F and the Würth Elektronik 151053YS04500?

A: Both are yellow LEDs in T-1 3/4 packages with compatible forward voltage. The primary differences are brightness (140mcd vs. 1500mcd) and viewing angle (24° vs. 45°). Selection depends on application brightness requirements and desired light distribution pattern.

Q: Can amber or orange LEDs from the Broadcom HLMP series replace the yellow MV8303?

A: Amber and orange LEDs are functional alternatives where color shift is acceptable. All Broadcom parts maintain T-1 3/4 package compatibility and operate at forward voltages (1.9V to 1.98V) close to the MV8303 (2.1V). Circuit redesign is minimal. Color change must be evaluated against application requirements.

Q: What is the difference between HLMP-EJ08 and HLMP-EJ15 orange LED variants?

A: Both are orange LEDs in T-1 3/4 packages with identical forward voltage (1.98V) and peak wavelength (609nm). The primary difference is viewing angle: HLMP-EJ08 provides 8° narrow angle, while HLMP-EJ15 provides 15° wider angle. Brightness varies within each series based on suffix designation.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification. The MV8303 does not specify RoHS status, but all active alternatives meet current regulatory requirements for new designs and procurement.

Q: Does the HLMP-EJ10-XZ0DD fit the same PCB layout as the MV8303?

A: The HLMP-EJ10-XZ0DD has a maximum height of 12.62mm compared to the MV8303 at 8.89mm. This 3.73mm height difference may require PCB layout verification. Other HLMP-EJ series parts maintain heights within 8.85mm to 8.91mm, compatible with MV8303 layout.

Q: What viewing angle should I select for my application?

A: Viewing angle selection depends on light distribution requirements. The MV8303 provides 20° viewing angle. Narrower angles (8° to 15°) concentrate light intensity in a specific direction. Wider angles (24° to 45°) distribute light across a broader area. Select based on application visibility requirements.
