MV6353 Yellow LED T-1 3/4 Through Hole Equivalent & Substitute Parts

Part Overview

The MV6353 is a yellow diffused LED in T-1 3/4 (5mm) through-hole package manufactured by onsemi. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The MV6353 delivers 15mcd brightness at 2.1V forward voltage with 20mA test current, designed for yellow indication applications in discrete LED circuits.

Substitute Part Grouping Explanation

Substitution of the MV6353 is determined by the following critical parameters:

Primary Compatibility Criteria:

Color: Yellow
Lens Transparency: Diffused
Lens Size: 5mm, T-1 3/4
Mounting Type: Through Hole
Package / Case: Radial

Secondary Electrical Criteria:

Voltage - Forward (Vf) Typical: 2.0V to 2.2V range
Current - Test: 10mA to 20mA range
Wavelength - Peak: 583nm to 585nm range
Viewing Angle: 50° to 65° range

Substitute parts are grouped into two categories based on lens transparency and electrical characteristics. Primary substitutes maintain diffused lens transparency with compatible forward voltage and current ratings. Secondary substitutes may vary in brightness (millicandela rating) or viewing angle while maintaining the core yellow diffused 5mm through-hole form factor.

Engineering Selection Recommendations

Primary Substitutes (Recommended for Direct Replacement):

HLMP-3401 and HLMP-3401-E0002 are the closest functional equivalents to the MV6353. Both maintain yellow diffused 5mm T-1 3/4 through-hole configuration with active product status and ROHS3 compliance. Forward voltage (2.0V) and wavelength (583nm) are within acceptable tolerance of the MV6353 specification. The primary difference is reduced brightness (5.7mcd versus 15mcd) and lower test current (10mA versus 20mA), which may require circuit design adjustment but maintains compatibility with standard through-hole PCB layouts.

Secondary Substitutes (Application-Dependent):

HLMP-3650 provides active product status and ROHS3 compliance in the same 5mm T-1 3/4 form factor but operates at 5V forward voltage. This part is suitable only for applications designed for higher voltage operation. The reduced brightness (2.2mcd) requires verification against application requirements.

Dialight 5219321F and 5219284F maintain yellow diffused lens transparency and through-hole mounting but use 4.83mm lens diameter (not standard T-1 3/4). These parts are suitable only if mechanical clearance permits non-standard lens size. 5219321F operates at 1.9V with minimal current (2mA), while 5219284F requires 10V operation.

Not Recommended for Direct Substitution:

4308H7 features clear (not diffused) lens transparency and significantly higher brightness (140mcd) with narrow viewing angle (24°). This part is suitable only for applications requiring high-intensity directional indication, not diffused general-purpose indication.

5219322F uses 3mm lens diameter, incompatible with standard 5mm through-hole PCB layouts.

5219327F is green, not yellow, and unsuitable for yellow indication applications.

Frequently Asked Questions (FAQ)

Q: Can HLMP-3401 directly replace MV6353 without circuit modification?

A: HLMP-3401 maintains compatible forward voltage (2.0V versus 2.1V) and wavelength (583nm versus 585nm) in the same 5mm T-1 3/4 through-hole package. However, reduced brightness (5.7mcd versus 15mcd) and lower test current (10mA versus 20mA) may require circuit resistor adjustment to achieve equivalent visual indication. Verify application brightness requirements before substitution.

Q: Why is 4308H7 not recommended despite yellow color and 5mm size?

A: 4308H7 uses clear lens transparency instead of diffused. This produces high-intensity directional light (140mcd, 24° viewing angle) suitable for focused indication, not the diffused general-purpose indication of MV6353 (15mcd, 65° viewing angle). Lens transparency fundamentally changes light distribution characteristics and is not interchangeable.

Q: Are Dialight 5219 series parts compatible with MV6353 PCB layouts?

A: Dialight 5219321F and 5219284F use 4.83mm lens diameter instead of standard 5mm T-1 3/4. While through-hole mounting is maintained, mechanical clearance and PCB hole sizing may differ. Verify PCB layout compatibility before substitution. 5219322F uses 3mm diameter and is not compatible with standard 5mm through-hole layouts.

Q: What is the voltage range for acceptable MV6353 substitutes?

A: Primary substitutes operate within 2.0V to 2.2V forward voltage range. HLMP-3650 operates at 5.0V and is suitable only for applications designed for higher voltage operation. Dialight 5219284F requires 10V and 5219321F operates at 1.9V. Verify circuit design voltage compatibility before substitution.

Q: Do all substitute parts meet ROHS3 compliance?

A: HLMP-3401, HLMP-3401-E0002, HLMP-3650, and all Dialight 5219 series parts are ROHS3 compliant. The original MV6353 does not specify RoHS status. Verify compliance requirements for your application before substitution.

Q: What is the difference between HLMP-3401 and HLMP-3401-E0002?

A: Both parts are electrically and functionally identical. HLMP-3401-E0002 is supplied in Cut Tape (CT) packaging with significantly higher inventory (35,845 pcs) compared to HLMP-3401 in Bulk packaging (2,300 pcs). Electrical specifications, brightness, and performance are equivalent.
