HLMP47009MP8A LED Circuit Board Indicator Equivalent & Substitute Parts

Part Overview

The HLMP47009MP8A is a quad red LED circuit board indicator manufactured by onsemi, featuring a 4-wide configuration with diffused, tinted lenses in a 5mm T-1 3/4 through-hole right-angle package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

The part operates at 1.8V with a 2mA rated current and delivers 2mcd luminous intensity at a 50° viewing angle. Its right-angle mounting configuration is specifically designed for circuit board indicator applications where vertical space is constrained.

Engineering Selection Recommendations

Direct Replacement (Preferred for Obsolete Part Mitigation): HLMP47009MP8 (onsemi) provides the closest functional equivalence, maintaining identical electrical specifications and optical performance. The only difference is mounting orientation; designs requiring right-angle mounting must retain the HLMP47009MP8A or evaluate mechanical redesign feasibility.

Active Product Alternatives: For new designs or long-term procurement security, Broadcom HLMP-3301 series parts offer active product status with compatible voltage (1.9V) and current (10mA test) specifications. HLMP-3301-D0000 and HLMP-3301-D0002 deliver 2.1mcd luminous intensity, closely matching the original 2mcd specification.

Würth Elektronik 151051RS11000 and VCC 4302H1-5V are suitable for applications where higher luminous intensity (30mcd and 8mcd respectively) is acceptable and circuit design accommodates their respective voltage requirements (2.1V and 5V).

All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can HLMP47009MP8 (vertical mount) replace HLMP47009MP8A (right-angle mount) directly? A: Electrically and optically, yes. However, the mounting orientation differs. HLMP47009MP8 is vertical through-hole while HLMP47009MP8A is right-angle. PCB layout and mechanical clearance must be evaluated before substitution.

Q: What is the key difference between HLMP-3301 variants (D0000, D0001, D0002, F0002)? A: Variants differ in packaging format (Bulk, Tape & Reel, Cut Tape) and millicandela rating. HLMP-3301-D0000 and D0001 deliver 2.1mcd; HLMP-3301-F0002 delivers 5.4mcd. Electrical specifications remain constant across variants.

Q: Is the 4302H1-5V suitable for 1.8V circuit designs? A: No. The 4302H1-5V requires 5V forward voltage and is designed for 13mA test current. It is suitable only for 5V indicator circuits. For low-voltage designs, use HLMP-3301 series (1.9V) or HLMP47009MP8 (1.8V).

Q: Why does 151051RS11000 have higher millicandela (30mcd) than the original (2mcd)? A: 151051RS11000 is a higher-brightness indicator LED. While it meets the 5mm T-1 3/4 form factor and diffused lens requirements, circuit design must account for the increased luminous intensity and 2.1V forward voltage.

Q: Are all substitute parts RoHS compliant? A: Yes. All listed substitutes carry ROHS3 compliance certification. The original HLMP47009MP8A is REACH Unaffected; all active product alternatives are ROHS3 Compliant.

Q: What packaging options are available for Broadcom HLMP-3301? A: HLMP-3301 is available in Bulk, Tape & Reel (TR), and Cut Tape (CT) packaging. Selection depends on procurement volume and assembly process requirements.

Q: Can I use a higher-current LED (10mA or 20mA test) in place of the 2mA original? A: Only if circuit design accommodates the increased current draw. The HLMP47009MP8A is rated for 2mA; substitutes with 10mA or 20mA test ratings require current-limiting resistor recalculation to maintain safe operating conditions.
