• Test Current: Both parts are rated at 20mA test current, maintaining consistent electrical operating conditions
• Lens Configuration: Both parts feature a diffused rectangular lens with identical 7.31mm x 2.35mm dimensions and flat-top styling
• Mounting Type: Both parts use through-hole radial mounting, ensuring mechanical compatibility with existing PCB layouts
• Physical Height: Both parts have a maximum height of 8.00mm, maintaining form factor consistency
• Package Type: Both parts use radial packaging suitable for through-hole applications

The HLMP-0401-B0000 is classified as active product status, providing ongoing availability and supply chain continuity compared to the obsolete HLMP-0405.

Parameter Comparison

Engineering Selection Recommendations

The HLMP-0401-B0000 is the designated substitute for the obsolete HLMP-0405. Selection of this substitute is supported by the following factors:

• Product Status: The HLMP-0401-B0000 maintains active product status with ongoing manufacturer support, whereas the HLMP-0405 is obsolete and subject to discontinuation
• Regulatory Compliance: The HLMP-0401-B0000 is ROHS3 compliant, meeting current environmental and regulatory requirements for electronic components
• Electrical Compatibility: Identical forward voltage (2.1V) and test current (20mA) specifications ensure direct circuit compatibility without design modification
• Optical Compatibility: Matching dominant wavelength (585nm), lens configuration, and diffused transparency maintain functional equivalence in indication applications
• Mechanical Compatibility: Identical lens dimensions (7.31mm x 2.35mm), mounting type (through-hole radial), and maximum height (8.00mm) ensure PCB layout compatibility

The HLMP-0401-B0000 is suitable for new designs and replacement applications where the HLMP-0405 is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the HLMP-0401-B0000 be used as a direct replacement for the HLMP-0405 in existing designs?

A: Yes. Both parts share identical forward voltage (2.1V), test current (20mA), lens dimensions (7.31mm x 2.35mm), mounting type (through-hole radial), and physical height (8.00mm). No circuit or PCB modifications are required.

Q: What are the differences between the HLMP-0405 and HLMP-0401-B0000?

A: The primary differences are product status (obsolete vs. active), millicandela rating (3.6mcd vs. 1.4mcd), viewing angle (70°/35° vs. 100°), peak wavelength (585nm vs. 583nm), and regulatory compliance (ROHS3 compliant for the substitute). The dominant wavelength remains 585nm for both parts.

Q: Does the lower millicandela rating of the HLMP-0401-B0000 affect compatibility?

A: The millicandela rating difference reflects brightness intensity. The HLMP-0401-B0000 produces lower brightness (1.4mcd) compared to the HLMP-0405 (3.6mcd). Application suitability depends on specific brightness requirements in the target circuit.

Q: Are there packaging differences between these parts?

A: The HLMP-0405 packaging is listed as standard, while the HLMP-0401-B0000 is supplied in bulk packaging. Both use radial through-hole packages suitable for PCB mounting.

Q: What is the viewing angle difference, and does it matter?

A: The HLMP-0405 has a viewing angle of 70° and 35°, while the HLMP-0401-B0000 has a 100° viewing angle. The wider viewing angle of the substitute may affect visibility characteristics in applications where directional indication is critical.

Q: Are both parts compliant with current environmental regulations?

A: The HLMP-0401-B0000 is ROHS3 compliant. Both parts are REACH unaffected and classified as EAR99 for export control purposes.
