Engineering Selection Recommendations

Direct Substitutes (Preferred for Pin-Compatible Replacement):

The Dialight 5520911803F and 5520911F are direct functional equivalents to the HLMP47009MP97. Both maintain identical dual-level configuration, 635nm wavelength, 1.8V voltage rating, 2mA current, 2mcd brightness, and 50° viewing angle. Both parts are active products with ROHS3 compliance and REACH unaffected status, ensuring long-term availability and regulatory alignment. The 5520911F offers higher inventory availability (1416 pcs) compared to 5520911803F (1089 pcs).

Similar Substitutes (Application-Dependent Selection):

The Broadcom HLMP-3301-D0000 provides a compatible alternative with nearly identical specifications (1.9V forward voltage, 635nm wavelength, 60° viewing angle, 2.1mcd). This part is active with ROHS3 compliance and substantial inventory (34,884 pcs). The slightly higher forward voltage (1.9V vs. 1.8V) and increased viewing angle (60° vs. 50°) require circuit verification but are acceptable for most circuit board indicator applications.

The Visual Communications Company 4302H1-5V operates at 5V with 10mA current and 8mcd brightness, suitable only for applications where higher voltage and current are available. The Würth Elektronik 151051RS11000 operates at 2.1V with 20mA current and 30mcd brightness, requiring circuit redesign for higher power applications.

All substitute parts maintain through-hole, right-angle mounting compatibility and diffused lens characteristics. Product status verification confirms all recommended substitutes are active, ensuring procurement continuity.

Frequently Asked Questions (FAQ)

Q: Can I use the Dialight 5520911F as a direct replacement for HLMP47009MP97?

A: Yes. The 5520911F is electrically and mechanically identical to the HLMP47009MP97. Both are dual-level red LEDs with 635nm wavelength, 1.8V rating, 2mA current, 2mcd brightness, 50° viewing angle, and 5mm right-angle through-hole mounting. No circuit modifications are required.

Q: What is the difference between the Dialight 5520911803F and 5520911F?

A: Both parts are functionally identical. The difference is packaging and inventory availability. The 5520911F has higher stock (1416 pcs vs. 1089 pcs). Verify packaging requirements (Bulk for both) against your procurement specifications.

Q: Can I substitute the Broadcom HLMP-3301-D0000 for the HLMP47009MP97?

A: The HLMP-3301-D0000 is compatible for most circuit board indicator applications. Key differences are forward voltage (1.9V vs. 1.8V) and viewing angle (60° vs. 50°). The slightly higher voltage and wider viewing angle are acceptable for standard indicator circuits but require verification in your specific application. Brightness (2.1mcd) is nearly identical.

Q: Why are some substitutes listed as "Similar" rather than "Direct"?

A: Direct substitutes maintain all critical parameters: dual-level configuration, 635nm wavelength, 1.8V voltage, 2mA current, 2mcd brightness, and 50° viewing angle. Similar substitutes vary in one or more parameters (voltage, current, brightness, viewing angle, or configuration) but remain compatible for circuit board indicator applications. Application-specific circuit analysis is required for similar substitutes.

Q: Are all substitute parts RoHS compliant?

A: Yes. All recommended substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The original HLMP47009MP97 RoHS status is not specified in available documentation.

Q: What is the impact of the 60° viewing angle on the Broadcom HLMP-3301-D0000 compared to the 50° angle of the original part?

A: A wider viewing angle (60° vs. 50°) means the LED light is distributed over a broader area, potentially appearing less bright when viewed directly but more visible from off-axis angles. For circuit board indicator applications, this is typically acceptable. Verify against your specific visibility requirements.

Q: Can I use the VCC 4302H1-5V or Würth Elektronik 151051RS11000 as substitutes?

A: These parts are compatible only if your circuit can accommodate higher voltage and current. The 4302H1-5V requires 5V and 10mA (vs. 1.8V and 2mA). The 151051RS11000 requires 2.1V and 20mA with higher brightness (30mcd). Circuit redesign is necessary for these substitutes. Use only if your application supports these electrical parameters.

Q: What packaging options are available for substitute parts?

A: Dialight 5520911803F and 5520911F are supplied in Bulk packaging. Broadcom HLMP-3301 variants are available in Bulk, Tape & Reel (TR), and Cut Tape (CT) packaging. Verify packaging compatibility with your assembly process before procurement.
