Substitute Part Grouping Explanation

Substitution for the HLMP47009MP7 is determined by the following critical parameters:

Lens Size & Mounting: 5mm T-1 3/4 through-hole configuration
Color & Lens Type: Red diffused lens
Electrical Characteristics: Forward voltage (1.8V–2.1V range), current rating (2mA–20mA), and brightness (2mcd–30mcd)
Viewing Angle: 45°–60° acceptable range
Mechanical Compatibility: Round domed top lens style, through-hole radial or right-angle mounting
Compliance: RoHS3 compliance and MSL 1 rating

Substitute parts are grouped into two categories: direct electrical equivalents with similar voltage and current ratings, and functional alternatives with compatible mechanical form factors but different electrical specifications requiring circuit design consideration.

Engineering Selection Recommendations

Primary Substitutes (Closest Electrical Match):

HLMP-3301-D0000, HLMP-3301-D0001, and HLMP-3301-D0002 from Broadcom Limited are the closest functional equivalents. These parts maintain the 5mm T-1 3/4 form factor, operate at 1.9V (within 0.1V of the original), and deliver 2.1mcd brightness matching the original specification. All variants are active products with ROHS3 compliance and MSL 1 rating. The primary difference is packaging format (bulk, tape & reel, or cut tape). HLMP-3301-D00B2 offers right-angle mounting identical to the original but lacks specified viewing angle data.

Secondary Substitutes (Voltage-Compatible, Higher Brightness):

HLMP-3301 and HLMP-3301-F0001 operate at 1.9V with 5.4mcd brightness, suitable for applications requiring increased visibility. These maintain mechanical compatibility but deliver higher luminous intensity.

Alternative Substitutes (Different Voltage Ratings):

4302H1-5V and 4302H1-12V from VCC provide 5mm T-1 3/4 form factors with 8mcd brightness but require circuit redesign due to different forward voltage ratings (5V and 12V respectively). These are suitable only when power supply voltage can be adjusted.

Mechanical Alternative:

151051RS11000 from Würth Elektronik offers a 4.90mm diameter lens with higher brightness (30mcd) and 2.1V forward voltage. The slightly smaller lens diameter may affect visual appearance in existing assemblies.

All recommended substitutes carry ROHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory and environmental compatibility.

Frequently Asked Questions (FAQ)

Q: Can HLMP-3301-D0000 directly replace HLMP47009MP7 without circuit modification?

A: Yes. Both parts operate at approximately 1.9V–1.8V forward voltage with 2mA–10mA current ratings and deliver comparable brightness (2.1mcd vs. 2mcd). The 5mm T-1 3/4 through-hole form factor is identical. No circuit redesign is required for standard indicator applications.

Q: What is the difference between HLMP-3301-D0000, HLMP-3301-D0001, and HLMP-3301-D0002?

A: These three parts are electrically and functionally identical. The differences are packaging formats only: D0000 is bulk, D0001 is tape & reel, and D0002 is cut tape. Select based on procurement and assembly requirements.

Q: Why does HLMP-3301-D00B2 have a right-angle mounting like the original but different specifications?

A: HLMP-3301-D00B2 is a circuit board indicator variant with right-angle mounting. While mechanically similar, it is specified as a 10mA component without detailed viewing angle data. Verify mechanical fit and electrical requirements before substitution.

Q: Can I use 4302H1-5V or 4302H1-12V as substitutes?

A: These parts are mechanically compatible (5mm T-1 3/4 form factor) but require circuit modification. The 4302H1-5V operates at 5V and 4302H1-12V at 12V, differing significantly from the original 1.8V rating. Use only if your power supply voltage matches and circuit design allows for the different forward voltage.

Q: Is the 151051RS11000 from Würth Elektronik a suitable substitute?

A: The 151051RS11000 is mechanically and electrically compatible with 2.1V forward voltage and 30mcd brightness. However, the lens diameter is 4.90mm versus the standard 5mm, which may affect visual appearance in existing assemblies. Verify mechanical fit in your application before use.

Q: Are all substitute parts RoHS compliant?

A: Yes. All recommended substitutes carry ROHS3 compliance and MSL 1 (unlimited) moisture sensitivity rating, ensuring regulatory and environmental compatibility with the original HLMP47009MP7.

Q: What viewing angle should I consider when selecting a substitute?

A: The original HLMP47009MP7 specifies 45° viewing angle. Most substitutes offer 60° viewing angle, providing wider visibility. If your application requires the narrower 45° angle, verify the substitute's viewing angle specification before selection.
