Substitute Part Grouping Explanation

Substitute parts for the HLMP47409MP94 are identified through strict parameter matching across the following critical dimensions:

Form Factor & Mounting Compatibility: All substitute parts maintain the 5mm T-1 3/4 lens size and through-hole mounting configuration, ensuring mechanical compatibility with existing PCB layouts and component footprints.

Optical Characteristics: Substitute parts are grouped by color (green) and peak wavelength (565nm), ensuring consistent visual appearance and spectral output within the green indicator spectrum.

Electrical Parameters: Substitutes are differentiated by forward voltage (Vf) and test current specifications. The HLMP47409MP94 operates at 1.9V/2mA. Substitute parts with different voltage ratings (5V, 12V) represent alternative circuit implementations and are not direct pin-compatible substitutes but rather functional equivalents for different power supply architectures.

Regulatory Compliance: All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring environmental and moisture sensitivity equivalence.

Brightness & Viewing Angle: The HLMP47409MP94 specifies 2.3mcd at 50° viewing angle. Substitute parts with higher brightness ratings (8mcd) and wider viewing angles (60°) provide enhanced visibility but represent performance upgrades rather than direct equivalents.

Engineering Selection Recommendations

Direct Electrical Equivalent: The HLMP-4740 manufactured by Broadcom Limited is the closest direct substitute for the HLMP47409MP94. Both parts share identical electrical specifications (1.9V forward voltage, 2mA test current, 2.3mcd brightness) and optical characteristics (565nm peak wavelength, 50° viewing angle, diffused lens). Both maintain Active product status and ROHS3 compliance. The HLMP-4740 is suitable for direct replacement in existing circuit designs without modification to current-limiting resistor values or power supply architecture. Inventory availability is significantly higher at 16,205 pieces.

Functional Equivalents with Voltage Adaptation: The 4302H5-5V and 4302H5-12V parts from Visual Communications Company represent functional equivalents requiring circuit redesign. These parts operate at higher forward voltages (5V and 12V respectively) and higher test currents (12-13mA), necessitating recalculation of series resistor values and verification of power supply compatibility. These parts offer enhanced brightness (8mcd) and wider viewing angle (60°) compared to the original specification. Selection of these parts is appropriate only when circuit architecture supports the higher voltage and current requirements.

Compliance & Regulatory Alignment: All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring regulatory equivalence for environmental and moisture sensitivity requirements. All parts carry EAR99 ECCN classification and 8541.41.0000 HTSUS code, maintaining consistent export and tariff classification.

Frequently Asked Questions (FAQ)

Q: Can the HLMP-4740 be used as a direct replacement for the HLMP47409MP94 without circuit modification?

A: Yes. The HLMP-4740 shares identical electrical parameters (1.9V, 2mA) and optical characteristics (2.3mcd, 50° viewing angle, 565nm peak wavelength). No changes to current-limiting resistors or power supply configuration are required. Both parts are ROHS3 compliant with MSL 1 rating.

Q: What is the key difference between the HLMP47409MP94 and the VCC 4302H5 series?

A: The primary differences are forward voltage and brightness. The HLMP47409MP94 operates at 1.9V with 2.3mcd output, while the 4302H5-5V operates at 5V with 8mcd output, and the 4302H5-12V operates at 12V with 8mcd output. These VCC parts require different circuit designs and are not pin-compatible substitutes without resistor recalculation.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts use 5mm T-1 3/4 through-hole form factor with round domed top lens and diffused transparency. The HLMP-4740 has a maximum height of 9.19mm, while the VCC 4302H5 series has a maximum height of 10.08mm. Both dimensions are within standard T-1 3/4 specifications and compatible with typical PCB layouts.

Q: Do the substitute parts maintain the same wavelength specification?

A: Yes. All substitute parts specify 565nm peak wavelength, ensuring consistent green color output across the green spectrum. The HLMP-4740 additionally specifies 569nm dominant wavelength, which falls within the green indicator range.

Q: What is the inventory status of substitute parts?

A: The HLMP-4740 (Broadcom) has 16,205 pieces in stock. The 4302H5-5V (VCC) has 2,739 pieces in stock. The 4302H5-12V (VCC) has 1,847 pieces in stock. The original HLMP47409MP94 (Everlight) has 921 pieces in stock.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring regulatory equivalence for environmental and reliability requirements.

Q: Can the 4302H5-5V and 4302H5-12V parts be used interchangeably?

A: No. These parts have different forward voltage specifications (5V vs. 12V) and require different circuit designs. Selection depends on the available power supply voltage in the target application. Both parts share identical brightness (8mcd), viewing angle (60°), and form factor specifications.
