Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MV54154 are qualified based on the following substitution criteria:

Critical Compatibility Parameters:

• Lens Size: 5mm, T-1 3/4 (physical form factor)
• Mounting Type: Through Hole (assembly compatibility)
• Color: Green (functional requirement)
• Package / Case: Radial (electrical connection configuration)
• RoHS Status: ROHS3 Compliant (regulatory requirement)

Electrical Compatibility Parameters:

• Voltage - Forward (Vf) (Typ): 2.1V to 2.2V range (circuit design tolerance)
• Current - Test: 10mA (standard operating condition)

Optical Performance Parameters:

• Wavelength - Peak: 565nm (green spectrum)
• Millicandela Rating: 6.7mcd to 12mcd (brightness range)
• Viewing Angle: 40° to 50° (optical coverage)
• Lens Transparency: Diffused or Clear (optical diffusion characteristic)

The identified substitutes HLMP-3554 and HLMP-3568 (both Broadcom Limited) meet all critical compatibility parameters. Variations in millicandela rating, viewing angle, and lens transparency represent acceptable performance trade-offs within the green LED indication category.

Parameter Comparison

Engineering Selection Recommendations

HLMP-3554 Selection Criteria: HLMP-3554 is suitable for applications where the MV54154 is unavailable and lower brightness output is acceptable. This substitute maintains diffused lens transparency identical to the main part, ensuring consistent optical diffusion characteristics. Forward voltage is 0.1V lower (2.1V vs 2.2V), which is within typical circuit design tolerance for LED indication circuits. Millicandela rating of 6.7mcd represents a 44% reduction in brightness compared to the MV54154. Viewing angle remains at 50°, matching the main part specification. ROHS3 compliance and MSL 1 rating are identical. This substitute is appropriate for non-critical indication applications where brightness reduction does not impact functional requirements.

HLMP-3568 Selection Criteria: HLMP-3568 is suitable for applications requiring higher brightness output than HLMP-3554 while accepting optical transparency differences. This substitute features clear lens transparency instead of diffused, resulting in more concentrated light output. Millicandela rating of 10.6mcd is 12% lower than the MV54154 but 58% higher than HLMP-3554. Viewing angle is reduced to 40° compared to the main part's 50°, indicating more directional light emission. Forward voltage is 2.1V, identical to HLMP-3554. ROHS3 compliance and MSL 1 rating are maintained. This substitute is appropriate for applications where directional indication with moderate brightness is required and the narrower viewing angle does not compromise visibility requirements.

Compliance Verification: All identified substitutes maintain ROHS3 compliance and MSL 1 (Unlimited) rating, ensuring regulatory and environmental compatibility with the original MV54154 specification.

Frequently Asked Questions (FAQ)

Q: Can HLMP-3554 be used as a direct replacement for MV54154 in all applications?

A: HLMP-3554 is physically and electrically compatible with MV54154 in through-hole PCB assemblies. However, the 44% reduction in brightness (6.7mcd vs 12mcd) must be evaluated against application visibility requirements. Both parts maintain identical 50° viewing angle and diffused lens transparency. Forward voltage difference of 0.1V is within standard circuit design tolerance for LED indication circuits.

Q: What is the primary difference between HLMP-3554 and HLMP-3568?

A: The primary differences are lens transparency and brightness output. HLMP-3554 features diffused transparency with 6.7mcd brightness and 50° viewing angle. HLMP-3568 features clear transparency with 10.6mcd brightness and 40° viewing angle. Both operate at 2.1V forward voltage. Selection depends on whether diffused or directional light output is required for the application.

Q: Are all three parts (MV54154, HLMP-3554, HLMP-3568) compatible with the same PCB footprint?

A: Yes. All three parts share identical physical specifications: 5mm T-1 3/4 lens size, 6.35mm maximum height, radial package configuration, and through-hole mounting type. PCB footprint compatibility is confirmed across all three parts.

Q: What is the forward voltage tolerance consideration when substituting these parts?

A: MV54154 operates at 2.2V typical forward voltage, while both HLMP-3554 and HLMP-3568 operate at 2.1V typical forward voltage. This 0.1V difference is within standard LED circuit design tolerance and does not require circuit modification for typical indication applications operating at 10mA test current.

Q: Do all substitute parts maintain the same regulatory compliance as MV54154?

A: Yes. MV54154, HLMP-3554, and HLMP-3568 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Regulatory and environmental compliance is maintained across all three parts.

Q: Which substitute part should be selected for maximum brightness retention?

A: HLMP-3568 provides the highest brightness among substitutes at 10.6mcd, representing 88% of the MV54154's 12mcd rating. However, HLMP-3568 features clear lens transparency and 40° viewing angle instead of the diffused transparency and 50° viewing angle of MV54154. Application requirements for optical diffusion and viewing angle must be evaluated before selection.

Q: Can HLMP-3568 be used in applications requiring diffused light output?

A: HLMP-3568 features clear lens transparency, which produces more concentrated, directional light output compared to diffused lenses. Applications specifically requiring diffused light characteristics should use HLMP-3554, which maintains the diffused transparency of the original MV54154.
