Substitute Part Grouping Explanation
Substitution eligibility for the HLMP47409MP94 is determined by the following critical parameters:
Primary Matching Criteria:
- Color: Green
- Wavelength - Peak: 565nm (±tolerance)
- Lens Type: Diffused
- Lens Size: 5mm, T-1 3/4
- Mounting Type: Through Hole
- Forward Voltage (Vf): 1.9V to 2.1V range
- Forward Current: 2mA to 20mA range
- Viewing Angle: 40° to 60°
- Millicandela Rating: 2.3mcd minimum

Engineering Selection Recommendations
HLMP-3507-D00B2 (Broadcom Limited) is the primary substitute for the HLMP47409MP94. This part maintains active product status, ROHS3 compliance, and MSL 1 rating. The forward voltage of 2.1V is within acceptable tolerance of the original 1.9V specification. The 10mA forward current and 4.2mcd brightness exceed the original part's 2mA and 2.3mcd ratings, providing improved performance margin. The right-angle through-hole mounting configuration matches the original design. This part is available in bulk packaging with 1,460 units in stock.
HLMP-3507 (Broadcom Limited) serves as an alternative with identical electrical characteristics to HLMP-3507-D00B2 but features standard radial mounting instead of right-angle configuration. This part is suitable for applications where mounting orientation can be adapted. Active product status and full compliance certifications apply.
151051VS04000 (Würth Elektronik) provides a high-brightness alternative at 140mcd with 2.1V forward voltage and 20mA current rating. The 40° viewing angle is narrower than the original 50°, and the 4.90mm lens diameter represents a minor dimensional variation. This part is recommended only for applications requiring significantly higher brightness output.
4302H5-5V (Visual Communications Company - VCC) operates at 5V forward voltage, requiring circuit redesign for integration. The 8mcd brightness and 60° viewing angle provide moderate performance. This part is suitable only when 5V operation is mandated by system architecture.
All substitute parts maintain ROHS3 compliance and MSL 1 ratings, ensuring compatibility with standard manufacturing and storage requirements.
Frequently Asked Questions (FAQ)
Q: Can HLMP-3507-D00B2 directly replace HLMP47409MP94 without circuit modification?
A: Yes. The 2.1V forward voltage of HLMP-3507-D00B2 is compatible with circuits designed for the original 1.9V part. The higher current rating (10mA vs. 2mA) requires verification that the driving circuit can supply this current, but the part will operate correctly at lower currents if the circuit is current-limited. The right-angle mounting configuration matches the original design.
Q: What is the significance of the wavelength difference between 565nm and 573nm?
A: Both wavelengths fall within the green spectrum and are visually indistinguishable to the human eye. The 565nm peak wavelength is the standard green LED specification. The 573nm variant from Würth Elektronik (151051VS04000) represents a minor shift within acceptable green LED parameters and is functionally equivalent for indicator applications.
Q: Why does HLMP47409MP94 have a "2 High" configuration while most substitutes are "Single"?
A: The HLMP47409MP94 contains two LED elements in series within a single package, resulting in the dual-level designation. Most substitute parts are single-element designs. For applications requiring dual-element functionality, HLMP-3507-D00B2 and HLMP-3507 provide single-element alternatives that can be implemented in parallel or series configurations depending on circuit design.
Q: Is the 4.90mm lens diameter of 151051VS04000 compatible with 5mm mounting holes?
A: The 4.90mm diameter is slightly smaller than the standard 5mm T-1 3/4 specification. This part is mechanically compatible with standard 5mm mounting holes but may require mechanical retention verification. Use this part only when brightness requirements justify the dimensional variation.
Q: What packaging options are available for substitute parts?
A: HLMP-3507-D00B2 is available in bulk packaging. HLMP-3507 is available in both bulk and tape & reel (TR) formats. HLMP-3507-D0002 is available in cut tape (CT) format. 151051VS04000 and 4302H5-5V are available in bulk packaging. Select packaging based on production volume and assembly process requirements.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings, ensuring compatibility with standard manufacturing processes and storage conditions.
