MV8333 Yellow LED T-1 3/4 Through Hole - Equivalent & Substitute Parts

Part Overview

The MV8333 is an active yellow LED indication component manufactured by Everlight Electronics Co Ltd, designed for through-hole mounting applications. This discrete 2.1V radial LED features a 5mm T-1 3/4 clear domed lens with 1500mcd brightness rating, suitable for standard indicator applications requiring yellow light output at 590nm peak wavelength. The component is ROHS3 compliant and maintains unlimited moisture sensitivity rating (MSL 1), making it suitable for general industrial and commercial electronic assemblies. Substitute parts are identified when equivalent functional performance can be achieved within the allowed electrical and mechanical parameter ranges for yellow LED indication components.

Engineering Selection Recommendations

Primary Application - MV8333 (Everlight): The MV8333 is the specified component for applications requiring 1500mcd brightness output with 30° viewing angle. This component is active, in stock (978 pcs), and ROHS3 compliant. Use this part when the full brightness specification and wider viewing angle are circuit requirements.

Substitute Application - 5219466F (Dialight): The Dialight 5219466F is a valid substitute when circuit design permits reduced brightness output (140mcd vs 1500mcd) and narrower viewing angle (24° vs 30°). This component is active, in stock (1273 pcs), and ROHS3 compliant. The forward voltage difference of 0.1V (2.2V vs 2.1V) is within standard tolerance for series resistor adjustment in indicator circuits. Mechanical fit is compatible with standard 5mm LED mounting holes.

Compliance Status: Both components maintain ROHS3 compliance and MSL 1 rating, suitable for standard industrial and commercial applications without additional environmental controls.

Frequently Asked Questions (FAQ)

Q: Can the 5219466F directly replace the MV8333 in all applications?

A: The 5219466F is mechanically and electrically compatible for through-hole mounting. However, the 1360mcd brightness reduction (140mcd vs 1500mcd) and 6° narrower viewing angle (24° vs 30°) must be evaluated against specific circuit requirements. Applications requiring the full 1500mcd brightness specification should use the MV8333.

Q: What is the forward voltage difference impact?

A: The 5219466F operates at 2.2V typical forward voltage compared to 2.1V for the MV8333. This 0.1V difference is within standard tolerance for LED indicator circuits and can be accommodated through series resistor adjustment without circuit redesign.

Q: Are the physical dimensions compatible?

A: Yes. The 5219466F lens diameter is 4.83mm (MV8333 is 5mm nominal), a 0.17mm difference within standard 5mm LED mounting hole tolerance. Maximum heights are 8.81mm (5219466F) and 8.89mm (MV8333), a 0.08mm difference that does not affect PCB clearance in standard applications.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the MV8333 and 5219466F are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating. Both carry EAR99 ECCN classification and HTSUS 8541.41.0000 tariff code.

Q: What is the wavelength difference between these parts?

A: The MV8333 has 590nm peak wavelength while the 5219466F has 583nm peak wavelength. Both fall within the yellow LED spectrum range and produce visually equivalent yellow light output for standard indication applications.

Q: Which part should be selected for new designs?

A: For new designs, specify the MV8333 when full 1500mcd brightness and 30° viewing angle are required. The 5219466F is appropriate for applications where reduced brightness and narrower viewing angle are acceptable, or when Dialight component qualification is required.
