HLMP1503 Equivalent & Substitute Parts Reference

Part Overview

The HLMP1503 is a green diffused LED indicator in T-1 (3mm) through-hole package manufactured by Everlight Electronics Co Ltd. This component is designed for discrete green LED indication applications with a forward voltage of 2.2V and a brightness rating of 5mcd. The part is currently in active production status with 1006 units available in inventory.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit operation within the electrical and mechanical tolerances of alternative manufacturers' offerings. The HLMP1503 has documented equivalent and similar parts available from onsemi and Broadcom Limited.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HLMP1503 is determined by strict alignment with the following critical parameters:

Primary Substitution Criteria:

• Color: Green
• Lens Transparency: Diffused
• Lens Size: 3mm, T-1
• Mounting Type: Through Hole
• Package / Case: Radial
• Wavelength - Peak: 562nm (±tolerance)

Secondary Electrical Parameters:

• Voltage - Forward (Vf) Typical: 2.2V (±tolerance)
• Current - Test: 20mA (±tolerance)
• Millicandela Rating: 5mcd (±tolerance)
• Viewing Angle: 90°

Parts are classified as Parametric Equivalent when all primary criteria and secondary electrical parameters align within acceptable engineering tolerances. Parts are classified as Similar when one or more secondary parameters deviate while primary criteria remain satisfied.

Engineering Selection Recommendations

HLMP1503 (Everlight Electronics Co Ltd) - Primary Selection

The HLMP1503 remains the recommended primary component. It is in active production status, ROHS3 compliant, and available in bulk packaging with 1006 units in stock. All electrical and mechanical parameters are fully specified and meet standard green LED indication requirements.

MV54643 (onsemi) - Parametric Equivalent

The MV54643 is a parametric equivalent with identical electrical specifications (2.2V forward voltage, 20mA test current, 5mcd brightness, 90° viewing angle) and mechanical compatibility (3mm T-1 radial package, 6.30mm height). However, this part is classified as obsolete. Selection of MV54643 is appropriate only when HLMP1503 supply is unavailable and long-term availability is not a design constraint. Inventory of 1891 units is currently available.

HLMP-1503-C0002 (Broadcom Limited) - Similar Part

The HLMP-1503-C0002 is classified as a similar part due to deviations in secondary electrical parameters. Key differences include: forward voltage of 2.1V (versus 2.2V), test current of 10mA (versus 20mA), brightness of 2.6mcd (versus 5mcd), and viewing angle of 60° (versus 90°). Wavelength peak is 565nm (versus 562nm). This part is in active production status and ROHS3 compliant. Selection is appropriate only when circuit design accommodates the reduced brightness and narrower viewing angle. Packaging is cut tape (CT) rather than bulk.

Frequently Asked Questions (FAQ)

Q: Can MV54643 be used as a direct replacement for HLMP1503?

A: MV54643 is a parametric equivalent with identical electrical and mechanical specifications. Direct substitution is electrically valid. However, MV54643 is classified as obsolete, which may present long-term supply and availability risks. Use only when HLMP1503 is unavailable and project timeline does not require extended component availability.

Q: What are the key differences between HLMP-1503-C0002 and HLMP1503?

A: HLMP-1503-C0002 differs in four secondary parameters: forward voltage (2.1V vs. 2.2V), test current (10mA vs. 20mA), brightness (2.6mcd vs. 5mcd), and viewing angle (60° vs. 90°). Wavelength peak also differs slightly (565nm vs. 562nm). These differences require circuit-level evaluation before substitution.

Q: Is HLMP-1503-C0002 suitable for applications requiring 5mcd brightness?

A: No. HLMP-1503-C0002 provides 2.6mcd brightness, which is approximately 48% of the HLMP1503 specification. Applications requiring 5mcd brightness cannot use this part without circuit redesign or acceptance of reduced indicator visibility.

Q: What is the viewing angle difference between HLMP1503 and HLMP-1503-C0002?

A: HLMP1503 has a 90° viewing angle, while HLMP-1503-C0002 has a 60° viewing angle. The 30° reduction in viewing angle narrows the cone of visibility and may affect indicator visibility from off-axis positions.

Q: Are all three parts RoHS3 compliant?

A: HLMP1503 and HLMP-1503-C0002 are both ROHS3 compliant. RoHS status for MV54643 is not specified in available documentation.

Q: What packaging formats are available?

A: HLMP1503 is supplied in bulk packaging. HLMP-1503-C0002 is supplied in cut tape (CT) format. MV54643 packaging format is not specified. Packaging selection depends on assembly process requirements and order quantity.

Q: Can these parts be used interchangeably in PCB assembly?

A: All three parts use identical through-hole radial package (T-1, 3mm). Physical PCB footprint compatibility is confirmed. Electrical interchangeability depends on circuit tolerance for the parameter variations listed in the comparison table.

Q: Which part should be selected for new designs?

A: HLMP1503 is the recommended selection for new designs. It is in active production, fully specified, ROHS3 compliant, and available in adequate inventory. MV54643 and HLMP-1503-C0002 are appropriate only for legacy design support or when specific parameter deviations are acceptable.
