Substitute Part Grouping Explanation

Substitution of the MV6154A is determined by the following critical parameters:

Color: Orange wavelength range (600nm to 635nm peak wavelength)
Lens Size & Form Factor: 5mm T-1 3/4 through-hole configuration
Lens Transparency: Diffused lens type
Voltage - Forward (Vf): 2V nominal operation
Mounting Type: Through-hole radial package
Brightness & Current: Millicandela rating and test current compatibility

Substitute parts are grouped into two categories based on these parameters:

Category 1 - Direct Orange LED Substitutes (Same Color, Similar Vf) Parts maintaining orange color, 2V forward voltage, and T-1 3/4 form factor with diffused lens.

Category 2 - Alternative Voltage Orange LED Substitutes Orange LED parts with different forward voltage ratings but compatible form factor and lens type, suitable for circuits with voltage adjustment capability.

Engineering Selection Recommendations

Primary Substitute: HLMP-D401 (Broadcom Limited)

The HLMP-D401 is the closest functional equivalent to the MV6154A. Both parts share orange color, T-1 3/4 form factor, diffused lens type, and through-hole radial mounting. The HLMP-D401 operates at 1.9V forward voltage (0.1V lower than MV6154A) and 10mA test current (half the MV6154A rating). The HLMP-D401 is active product status with ROHS3 compliance and REACH unaffected certification, ensuring long-term availability and regulatory compliance.

Secondary Substitute: 5219704F (Dialight)

The 5219704F provides orange LED indication with 1.9V forward voltage and diffused lens in a through-hole configuration. This part is active status with ROHS3 compliance. The lens diameter is 4.83mm (slightly smaller than standard 5mm), which may require mechanical verification in existing PCB layouts.

Alternative Voltage Options:

Yellow LED substitutes (HLMP-3401, HLMP-3650, HLMP-3651, HLMP-4719 series) are available from Broadcom Limited with different forward voltage ratings (1.8V, 2V, 5V, 12V). These parts maintain T-1 3/4 form factor and through-hole mounting but differ in color (yellow vs. orange) and brightness characteristics. Selection of yellow alternatives requires circuit design review and visual indication acceptance.

All recommended substitutes carry active product status and ROHS3 compliance, ensuring regulatory alignment and procurement continuity.

Frequently Asked Questions (FAQ)

Q: Can HLMP-D401 directly replace MV6154A without circuit modification?

A: The HLMP-D401 operates at 1.9V forward voltage compared to MV6154A's 2V, a 0.1V difference within typical LED tolerance ranges. Test current differs (10mA vs. 20mA), requiring series resistor adjustment in the circuit. Mechanical fit is compatible due to identical T-1 3/4 form factor and through-hole radial package.

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

A: Both parts are identical in electrical specifications (2V, 10mA, 5.7mcd yellow LED). The difference is packaging: HLMP-3401 is supplied in bulk, while HLMP-3401-E0002 is supplied in cut tape format. Functional performance is equivalent.

Q: Why are yellow LED options listed as substitutes for an orange LED?

A: Yellow LED parts (HLMP-3401, HLMP-3650, HLMP-3651, HLMP-4719 series) share identical mechanical form factors (5mm T-1 3/4 through-hole) and mounting compatibility with the MV6154A. These are listed as alternatives for applications where color change is acceptable or where specific voltage requirements (5V, 12V) match circuit design better than orange options.

Q: What is the significance of product status (Active vs. Obsolete)?

A: Active product status indicates current manufacturing and long-term availability. The MV6154A is obsolete, meaning onsemi no longer manufactures this part. Active substitutes from Broadcom Limited and Dialight ensure reliable procurement and design continuity for new production runs.

Q: Are all listed substitutes ROHS3 compliant?

A: All substitute parts listed carry ROHS3 compliance certification. The original MV6154A does not specify RoHS status. All substitutes are REACH unaffected, meeting current environmental and regulatory requirements.

Q: How do viewing angles affect LED substitution?

A: The MV6154A has a 24° viewing angle (narrow, directional). Most substitutes (HLMP-D401, HLMP-3401 series) have 60° viewing angles (wider, more diffuse). This affects light distribution in the application. Narrow-angle applications may require optical design review when switching to wider-angle substitutes.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in bulk and cut tape formats. HLMP-3401-E0002 and HLMP-4719-A0002 are supplied in cut tape for automated assembly. Bulk packaging is standard for manual assembly or lower-volume applications. Packaging selection depends on manufacturing process requirements.
