HLMP47409MP8 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The HLMP47409MP8 is a quad green LED circuit board indicator manufactured by onsemi, featuring four 5mm diffused green LEDs in a single through-hole package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The part operates at 1.9V with a 2mA test current and provides 2.3 millicandela brightness at a 50° viewing angle. Substitutes must maintain compatibility with the quad configuration, green wavelength specification, and through-hole mounting requirement while accommodating modern active alternatives.

Substitute Part Grouping Explanation

Substitution logic for the HLMP47409MP8 is determined by the following critical parameters:

Primary Compatibility Criteria:

Color: Green wavelength in the 565-573nm range
Lens Type: Diffused optical characteristics
Lens Size: 5mm form factor (T-1 3/4)
Mounting Type: Through-hole configuration
Voltage Rating: Forward voltage between 1.9V and 5V
Current Rating: Test current between 2mA and 20mA

Configuration Consideration: The HLMP47409MP8 is a quad (4-wide) configuration. Single-LED substitutes from the HLMP-3507 series and other manufacturers provide functional equivalence when four units are used in parallel or series-parallel arrangements within the circuit design.

Substitutes are grouped into two categories:

Direct Quad Alternatives - Parts maintaining the multi-LED configuration
Single-LED Alternatives - Individual green LEDs that can replace the quad through circuit redesign

All listed substitutes maintain green color, diffused lens type, 5mm through-hole mounting, and operate within compatible voltage and current ranges.

Engineering Selection Recommendations

For Active Production Designs:

The HLMP-3507 series from Broadcom Limited represents the primary substitute path. HLMP-3507, HLMP-3507-D0001, and HLMP-3507-D0002 are functionally identical single-LED alternatives with active product status and ROHS3 compliance. These parts operate at 2.1V with 10mA test current and maintain the 565nm peak wavelength and 5mm T-1 3/4 form factor. Four units can be configured in series-parallel arrangements to replicate the quad functionality of the HLMP47409MP8.

The 4302H5-5V from Visual Communications Company provides an alternative at 5V operation with identical 5mm T-1 3/4 form factor and ROHS3 compliance. This option is suitable for 5V logic-level circuits.

The 151051VS04000 from Würth Elektronik offers higher brightness (140mcd) at 2.1V operation with active status and ROHS3 compliance, though the lens diameter is slightly reduced to 4.90mm.

For Voltage-Specific Applications:

The HLMP-3680 operates at 5V with lower brightness (1.6mcd), suitable for applications requiring higher supply voltage with reduced luminous intensity.

The 4302H5-12V accommodates 12V supply circuits with 8mcd brightness and active product status.

Compliance Considerations:

All recommended substitutes maintain MSL 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status, matching the original part's environmental specifications. ROHS3 compliance is standard across active alternatives.

Frequently Asked Questions (FAQ)

Q: Can a single HLMP-3507 directly replace the HLMP47409MP8?

A: No. The HLMP47409MP8 is a quad configuration (four LEDs in one package), while HLMP-3507 is a single LED. Four HLMP-3507 units must be integrated into the circuit design using series-parallel configuration to achieve equivalent functionality. Circuit redesign is required.

Q: What is the primary difference between HLMP-3507 variants (D0001, D0002, D00B1, D00B2)?

A: The variants differ in packaging format and mounting orientation. HLMP-3507 and HLMP-3507-D0001 are standard radial through-hole. HLMP-3507-D0002 is cut tape packaging. HLMP-3507-D00B1 and HLMP-3507-D00B2 feature right-angle mounting. All maintain identical electrical specifications (2.1V, 10mA, 4.2mcd, 565nm).

Q: Is the 151051VS04000 compatible with the same circuit as HLMP47409MP8?

A: The 151051VS04000 maintains green color, diffused lens, 5mm form factor, and through-hole mounting. However, it operates at 2.1V with 20mA test current and delivers significantly higher brightness (140mcd). Circuit current-limiting resistor values must be recalculated. The lens diameter is 4.90mm versus the original 5mm specification.

Q: Why is HLMP-3507-EF000 listed if it is obsolete?

A: HLMP-3507-EF000 is included for reference as a historical variant within the HLMP-3507 base product family. It offers higher brightness (13.9mcd) but shares obsolete status with the original HLMP47409MP8. Active alternatives are recommended for new designs.

Q: What voltage should I select for my replacement LED?

A: Select based on your circuit supply voltage. For 1.9V-2.1V circuits, use HLMP-3507 series. For 5V circuits, use HLMP-3680 or 4302H5-5V. For 12V circuits, use 4302H5-12V. Verify that your current-limiting resistor design accommodates the selected forward voltage and test current specifications.

Q: Are all substitutes ROHS3 compliant?

A: All active-status substitutes listed are ROHS3 compliant. HLMP-3507-EF000 is obsolete and ROHS3 compliant. The original HLMP47409MP8 RoHS status is not specified in available documentation.

Q: Can I use the right-angle mounting variants (D00B1, D00B2) as direct replacements?

A: Right-angle variants (HLMP-3507-D00B1, HLMP-3507-D00B2) have different mechanical mounting orientation compared to standard radial through-hole. They are electrically equivalent but require PCB layout modification. Use only if your design accommodates right-angle LED mounting.
