HLMP0301 Equivalent & Substitute Parts

Part Overview

The HLMP0301 is a red diffused rectangular through-hole LED manufactured by onsemi, designed for indication applications requiring discrete 2.1V operation. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The HLMP0301 delivers 5mcd brightness with a 100° viewing angle in a compact rectangular lens format (7.24mm × 2.42mm) suitable for panel-mount indicator circuits.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HLMP0301 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Color: Red
• Lens Transparency: Diffused
• Lens Style: Rectangle with Flat Top
• Mounting Type: Through Hole
• Package / Case: Radial
• Height (Max): 8.00mm
• Current - Test: 20mA
• Viewing Angle: 100°

Allowable Variation Parameters:

• Voltage - Forward (Vf) (Typ): ±0.3V tolerance acceptable for indication circuits
• Millicandela Rating: Brightness variation acceptable within application requirements
• Lens Size: Minor dimensional variation (±0.1mm) acceptable for rectangular format
• Wavelength - Peak: Red spectrum variation (626nm–645nm) acceptable for visual indication

The three substitute parts (HLMP-0301, HLMP-0301-C0000, and HLMP-R100) all manufactured by Broadcom Limited maintain identical mechanical form factors, mounting characteristics, and optical properties while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

HLMP-0301 (Broadcom Limited) is the primary substitute for HLMP0301. This part maintains identical mechanical and optical specifications while offering active product status and ROHS3 compliance. Forward voltage reduction from 2.1V to 1.9V requires circuit-level current limiting adjustment but does not affect form factor compatibility. Brightness output of 2.1mcd is suitable for standard indication applications.

HLMP-0301-C0000 (Broadcom Limited) provides an alternative with identical mechanical compatibility and ROHS3 compliance. The reduced brightness rating of 1.3mcd is appropriate for applications where lower luminous intensity is acceptable or preferred. Forward voltage of 1.9V matches the primary HLMP-0301 substitute.

HLMP-R100 (Broadcom Limited) offers the lowest forward voltage at 1.8V with 2.1mcd brightness output. Peak wavelength extends to 645nm within the red spectrum range. This part is suitable for applications requiring minimal power consumption while maintaining adequate visual indication.

All three Broadcom substitutes provide ROHS3 compliance and REACH Unaffected status, meeting modern regulatory requirements. Active product status ensures long-term availability and supply chain stability compared to the obsolete HLMP0301.

Frequently Asked Questions (FAQ)

Q: Can HLMP-0301 (Broadcom) directly replace HLMP0301 (onsemi) without circuit modification?

A: Mechanical and optical compatibility is direct. Forward voltage differs by 0.2V (2.1V to 1.9V), requiring adjustment of series current-limiting resistor values to maintain 20mA test current. Lens dimensions vary by approximately 0.1mm, which is negligible for standard panel-mount applications.

Q: What is the brightness difference between HLMP0301 and its substitutes?

A: HLMP0301 delivers 5mcd. HLMP-0301 and HLMP-R100 both provide 2.1mcd, while HLMP-0301-C0000 provides 1.3mcd. For standard indication circuits, 2.1mcd output is sufficient. Applications requiring higher brightness should evaluate circuit design or alternative LED families.

Q: Are all substitutes RoHS compliant?

A: Yes. All three Broadcom substitutes (HLMP-0301, HLMP-0301-C0000, HLMP-R100) are ROHS3 compliant. The original HLMP0301 does not specify RoHS status.

Q: Which substitute offers the best power efficiency?

A: HLMP-R100 operates at the lowest forward voltage (1.8V) at 20mA test current, resulting in the lowest power dissipation. This part is optimal for battery-powered or power-constrained applications.

Q: Do all substitutes maintain the same viewing angle?

A: Yes. All parts maintain a 100° viewing angle, ensuring identical optical performance in indication circuits.

Q: What is the wavelength difference between substitutes?

A: HLMP-0301 and HLMP-0301-C0000 peak at 635nm. HLMP-R100 peaks at 645nm. Both wavelengths fall within the red spectrum and are visually indistinguishable for indication applications.

Q: Are there inventory considerations for part selection?

A: HLMP-0301 (Broadcom) has 7,659 units in stock. HLMP-0301-C0000 has 852 units. HLMP-R100 has 858 units. Availability should be confirmed for production volume requirements.
