MV8341 LED Yellow Clear T-1 3/4 Through Hole Equivalent & Substitute Parts

Part Overview

The onsemi MV8341 is a yellow LED indication component in T-1 3/4 through-hole package format, rated at 240 millicandela with a 2.1V forward voltage and 45° viewing angle. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. Substitute components must maintain compatibility with the original electrical specifications, mechanical form factor, and mounting requirements while meeting current product availability and compliance standards.

Substitute Part Grouping Explanation

Substitution logic for the MV8341 is based on the following critical parameters:

Primary Compatibility Criteria:

Color: Yellow (exact match required for indication function)
Lens Size: 5mm, T-1 3/4 (mechanical fit in PCB through-hole mounting)
Mounting Type: Through Hole (assembly compatibility)
Package / Case: Radial (lead configuration)
Lens Transparency: Clear (optical performance)

Secondary Electrical Criteria:

Voltage - Forward (Vf): 2.1V nominal (circuit design tolerance typically ±0.2V)
Current - Test: 20mA (standard test condition)
Wavelength - Peak: 590nm (yellow spectrum range)

Acceptable Variation Parameters:

Millicandela Rating: Brightness variation acceptable within application requirements
Viewing Angle: Variation acceptable based on circuit board layout and visibility requirements
Height (Max): Minor variations acceptable if within PCB clearance envelope

The substitute part 5219466F (Dialight) meets primary compatibility criteria but differs in color (yellow maintained), brightness (140mcd vs 240mcd), and viewing angle (24° vs 45°). This part is suitable only for applications where reduced brightness and narrower viewing angle are acceptable.

All Broadcom HLMP-EJ series parts listed are orange LEDs (605nm wavelength), not yellow. These parts do not meet the primary color requirement and are not valid substitutes for yellow indication applications.

Engineering Selection Recommendations

Valid Substitute:

The Dialight 5219466F is the only part in the provided list that meets the primary color requirement for yellow LED indication. This part maintains yellow color specification, through-hole radial mounting, and 20mA test current compatibility. The 5219466F is currently in active production status with ROHS3 compliance, addressing the obsolescence of the MV8341. Forward voltage is 2.2V (0.1V higher than MV8341), which falls within typical circuit design tolerance. Brightness is reduced to 140mcd from 240mcd, and viewing angle narrows to 24° from 45°. Selection of the 5219466F requires confirmation that reduced brightness and narrower viewing angle are acceptable for the intended application.

Invalid Substitutes:

All Broadcom HLMP-EJ series parts listed (HLMP-EJ08-WZ000, HLMP-EJ08-X1000, HLMP-EJ08-Y2000, HLMP-EJ10-XZ0DD, HLMP-EJ15-PS000, HLMP-EJ15-SV000, HLMP-EJ15-SV0DD, HLMP-EJ17-SV000, HLMP-EJ24-QT000) are orange LEDs with 605nm peak wavelength. These parts do not meet the color specification requirement and are not suitable substitutes for yellow indication applications.

Frequently Asked Questions (FAQ)

Q: Why is the MV8341 listed as obsolete?

A: The MV8341 is classified as obsolete by onsemi, indicating it is no longer in active production. Replacement parts must be sourced from remaining inventory or equivalent alternatives.

Q: Can I use an orange LED instead of yellow?

A: No. Orange and yellow LEDs have different peak wavelengths (605nm vs 590nm) and produce visually distinct colors. Substitution requires matching the color specification for proper indication function.

Q: What is the impact of using the 5219466F with lower brightness (140mcd vs 240mcd)?

A: Brightness reduction affects visibility distance and intensity. The 5219466F is suitable only if the application can tolerate reduced brightness. Verify visibility requirements under intended lighting conditions.

Q: Does the narrower viewing angle of the 5219466F (24° vs 45°) affect compatibility?

A: Viewing angle determines the cone of visibility from different angles. The 5219466F has a narrower viewing angle, which may limit visibility from off-axis positions. Confirm that the narrower angle is acceptable for the circuit board layout and intended viewing positions.

Q: Are the Broadcom HLMP-EJ parts compatible with the MV8341?

A: No. All listed Broadcom HLMP-EJ parts are orange LEDs, not yellow. They do not meet the color requirement and are not valid substitutes.

Q: What is the forward voltage difference between MV8341 and 5219466F?

A: The MV8341 has a typical forward voltage of 2.1V, while the 5219466F is 2.2V. This 0.1V difference is within standard circuit design tolerance for LED applications and does not prevent substitution.

Q: Are there packaging differences between MV8341 and 5219466F?

A: The MV8341 is supplied in standard packaging, while the 5219466F is supplied in bulk packaging. Both use radial through-hole configuration compatible with standard PCB mounting.

Q: Is the 5219466F RoHS compliant?

A: Yes. The 5219466F is ROHS3 compliant, meeting current environmental and material restriction standards.
