Substitute Part Grouping Explanation
Substitution for the HLMP47009MP8 is determined by the following critical parameters:
Primary Compatibility Criteria:
- Color: Red
- Lens Type: Diffused
- Lens Size: 5mm, T-1 3/4
- Mounting Type: Through Hole
- Wavelength - Peak: 635nm (±15nm tolerance acceptable)
- Voltage Rating: 1.8V to 2.1V forward voltage
- Current: 2mA to 20mA test current
- Viewing Angle: 50° to 60°
The substitute parts listed are single-LED alternatives to the quad configuration of the main part. Each substitute operates as an individual LED indicator with compatible electrical and mechanical specifications. Substitution requires circuit redesign to accommodate single LEDs instead of the integrated quad package, but electrical performance remains within acceptable parameters for standard indicator applications.

Engineering Selection Recommendations
Closest Electrical Match: HLMP-3301-D0000 and HLMP-3301-D0002 provide the closest electrical substitution with 1.9V forward voltage, 2.1mcd brightness, and 10mA test current. Both are active products with ROHS3 compliance and MSL 1 rating. The primary difference is packaging: HLMP-3301-D0000 is supplied in bulk, while HLMP-3301-D0002 is cut tape format.
Alternative with Higher Brightness: HLMP-3301-F0002 offers 5.4mcd brightness at identical 1.9V and 10mA specifications, suitable for applications requiring increased visibility while maintaining electrical compatibility.
Higher Voltage Options: 4302H1-5V operates at 5V with 8mcd brightness and 10mA current, appropriate for 5V logic-level circuits. 4302H1-12V operates at 12V with 13mA current for 12V system integration.
All substitute parts are active products with current manufacturing status and ROHS3 compliance, ensuring long-term availability and regulatory compliance for new designs.
Frequently Asked Questions (FAQ)
Q: Can I directly replace the HLMP47009MP8 quad LED with a single substitute LED?
A: No. The HLMP47009MP8 contains four integrated LEDs in one package, while all substitutes are single LEDs. Circuit redesign is required to accommodate four individual LED packages or alternative quad configurations. Electrical parameters remain compatible, but physical layout and PCB routing must be modified.
Q: Which substitute offers the closest brightness match?
A: HLMP-3301-D0000 and HLMP-3301-D0002 deliver 2.1mcd, closest to the original 2mcd specification. HLMP-3301-F0002 provides 5.4mcd for applications requiring higher visibility.
Q: Are all substitutes RoHS compliant?
A: All listed substitutes are ROHS3 compliant. The original HLMP47009MP8 RoHS status is not specified in available documentation.
Q: What is the difference between HLMP-3301-D0000 and HLMP-3301-D0002?
A: Both parts are electrically identical (1.9V, 2.1mcd, 10mA). The difference is packaging: HLMP-3301-D0000 is bulk packaging, while HLMP-3301-D0002 is cut tape format. Select based on assembly process requirements.
Q: Can I use 4302H1-5V or 4302H1-12V as substitutes?
A: These parts are mechanically and optically compatible but operate at different voltages (5V and 12V respectively). Use only if your circuit design accommodates these voltage levels. They are not suitable for 1.8V to 2.1V circuits without additional voltage regulation.
Q: What is the viewing angle difference between the main part and substitutes?
A: The HLMP47009MP8 has a 50° viewing angle, while all substitutes have 60° viewing angles. The wider angle provides better visibility across a broader range but may affect optical performance in applications requiring narrow-angle indication.
Q: Are moisture sensitivity levels identical across all parts?
A: Yes. All parts, including the original and all substitutes, have MSL 1 (Unlimited) rating, indicating no moisture sensitivity concerns for storage and handling.
