HLMP47009MP6 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The HLMP47009MP6 is a red diffused LED circuit board indicator manufactured by onsemi, designed for through-hole, right-angle mounting in 5mm T-1 3/4 form factor. This component operates at 1.8V with 2mA current and delivers 2mcd brightness. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain compatibility with the original electrical specifications, mechanical form factor, and mounting configuration.

Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on electrical and mechanical compatibility with the HLMP47009MP6:

Direct Manufacturer Substitutes (onsemi): Parts sharing identical base product number (HLMP47), voltage rating (1.8V), current specification (2mA), lens size (5mm T-1 3/4), mounting type (through hole, right angle), and diffused red lens configuration. These parts are interchangeable at the circuit level with minimal or no design modification.

Similar Manufacturer Substitutes (Alternative Manufacturers): Parts from Broadcom Limited, Würth Elektronik, and Visual Communications Company that maintain compatibility across critical parameters: red color, diffused lens, 5mm T-1 3/4 form factor, through-hole mounting, and voltage/current operating ranges suitable for low-power indicator applications. These substitutes may require circuit-level verification due to variations in forward voltage, brightness output, or viewing angle.

Key parameters determining substitution eligibility:

Lens size and form factor (5mm T-1 3/4)
Mounting type (through hole, right angle)
Color and lens transparency (red, diffused)
Voltage and current compatibility
Mechanical dimensions and pin configuration

Engineering Selection Recommendations

Direct Substitution (onsemi HLMP47009MP7): This part maintains identical electrical specifications (1.8V, 2mA, 2mcd) and mechanical configuration (5mm T-1 3/4, right-angle through-hole) as the HLMP47009MP6. Both parts are obsolete but remain ROHS3 compliant. Selection of HLMP47009MP7 requires no circuit modification and provides pin-for-pin compatibility.

Broadcom HLMP-3301 Series (D0000, D0001, D0002, F0002): These parts operate at 1.9V forward voltage with 10mA test current and deliver 2.1mcd to 5.4mcd brightness depending on variant. The 0.1V voltage increase and 8mA current increase from the original specification require circuit-level evaluation. All variants maintain 5mm T-1 3/4 form factor and through-hole mounting. Packaging options include bulk, tape & reel, and cut tape. These parts are active products with ROHS3 compliance.

Würth Elektronik 151051RS11000: This part operates at 2.1V with 20mA test current and delivers 30mcd brightness. The significantly higher brightness output and current requirement necessitate circuit redesign. Lens diameter is 4.90mm, slightly smaller than the 5mm standard. Suitable only for applications where increased brightness is acceptable and circuit modifications are feasible.

Visual Communications Company 4302H1-5V and 4302H1-12V: The 5V variant (4302H1-5V) operates at 5V forward voltage with 10mA test current and 8mcd brightness. The 12V variant (4302H1-12V) operates at 12V with 13mA test current. Both require significant circuit modification due to voltage incompatibility with the original 1.8V specification. These parts are suitable only for applications with different power supply architectures.

Selection priority based on product status and compliance:

HLMP47009MP7 for direct replacement in existing designs
Broadcom HLMP-3301 series for new designs requiring active product status
Alternative manufacturers only when specific brightness or voltage requirements differ from original specification

Frequently Asked Questions (FAQ)

Q: Can HLMP47009MP7 be used as a direct replacement for HLMP47009MP6? A: Yes. Both parts share identical electrical specifications (1.8V, 2mA, 2mcd), mechanical form factor (5mm T-1 3/4), and mounting configuration (through-hole, right-angle). No circuit modification is required. Both parts are obsolete but ROHS3 compliant.

Q: What is the primary difference between HLMP47009MP6 and Broadcom HLMP-3301 series? A: The Broadcom parts operate at 1.9V forward voltage (0.1V higher) with 10mA test current (8mA higher than the original 2mA specification). Brightness ranges from 2.1mcd to 5.4mcd depending on variant. Circuit-level evaluation is required before substitution. Broadcom parts are active products, whereas the original is obsolete.

Q: Are the Broadcom HLMP-3301-D0001 and HLMP-3301-D0002 interchangeable? A: Both parts have identical electrical specifications (1.9V, 10mA, 2.1mcd) and mechanical dimensions. The difference is packaging: D0001 is supplied in tape & reel format, while D0002 is supplied in cut tape format. Selection depends on assembly process requirements, not electrical compatibility.

Q: Why do the Würth Elektronik and VCC parts require circuit modification? A: Würth Elektronik 151051RS11000 operates at 2.1V with 20mA current and delivers 30mcd brightness—significantly higher than the original 1.8V, 2mA, 2mcd specification. VCC 4302H1-5V and 4302H1-12V operate at 5V and 12V respectively, incompatible with the original 1.8V design. These parts are suitable only for applications with different power supply and brightness requirements.

Q: What packaging options are available for Broadcom HLMP-3301 series? A: Broadcom offers HLMP-3301-D0000 in bulk packaging, HLMP-3301-D0001 in tape & reel, and HLMP-3301-D0002 in cut tape. HLMP-3301-F0002 is also available in cut tape with 5.4mcd brightness. Selection depends on production volume and assembly automation requirements.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All substitute parts listed—onsemi HLMP47009MP7, Broadcom HLMP-3301 series, Würth Elektronik 151051RS11000, and VCC 4302H1 series—are ROHS3 compliant with MSL rating of 1 (unlimited moisture sensitivity level).

Q: Can HLMP-3301-D00B2 be used as a substitute? A: HLMP-3301-D00B2 is a right-angle circuit board indicator variant with 1.9V, 10mA, and 2.1mcd specifications. While it shares the right-angle mounting configuration with the original, it is classified as a circuit board indicator rather than a standard through-hole LED. Mechanical compatibility requires verification before substitution.

Q: What is the viewing angle difference between the original and substitute parts? A: The original HLMP47009MP6 has a 45° viewing angle. Most substitute parts (Broadcom, Würth Elektronik, VCC) have 60° viewing angles. The wider viewing angle may affect application-specific visibility requirements in narrow-angle indicator applications.
