Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HLMP0301 are identified based on strict alignment with the following critical parameters:

Primary Substitution Criteria:

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

Secondary Compatibility Parameters:

• Voltage - Forward (Vf) Typical: Range 1.9V to 2.1V (acceptable operating range)
• Viewing Angle: 80° to 110° (functional tolerance)
• Wavelength - Peak: 632nm to 635nm (red spectrum consistency)

The three substitute parts listed below meet these criteria and are available from active product lines, providing direct functional replacement capability for the obsolete HLMP0301.

Parameter Comparison

Engineering Selection Recommendations

HLMP-0301 (Broadcom Limited) is the primary substitute for the obsolete Everlight HLMP0301. This part maintains identical mechanical dimensions (8.00mm height, 7.31mm x 2.35mm lens size) and electrical characteristics (1.9V forward voltage, 20mA test current, 100° viewing angle, 635nm peak wavelength). The Broadcom variant is currently in active production status with ROHS3 compliance certification and 7,659 units available in inventory. The forward voltage differential of 0.2V is within acceptable operating tolerance for standard LED indication circuits.

SSL-LX25783ID (Lumex Opto/Components Inc.) provides an alternative substitute with compatible mechanical and electrical parameters. This part maintains the 8.00mm maximum height and operates at 2.0V forward voltage with 20mA test current. The lens dimensions (7.00mm x 2.30mm) are closely matched to the original HLMP0301. The 80° viewing angle represents a narrower field compared to the original 100°, which may affect application suitability depending on circuit design requirements. This part is ROHS3 compliant and currently active with 2,100 units in inventory.

EALP03RRARA0 (Everlight Electronics Co Ltd) is available as a substitute from the original manufacturer. This part operates at 2.0V forward voltage and maintains the same 20mA test current and radial through-hole package configuration. The lens dimensions (5.71mm x 3.17mm) and height (7.41mm) differ from the original HLMP0301, which may require mechanical re-evaluation for PCB layout compatibility. The 50mcd millicandela rating is significantly higher than the original 5mcd, which may necessitate circuit current limiting adjustments. This part is ROHS3 compliant and currently active with 927 units in inventory.

Frequently Asked Questions (FAQ)

Q: Can the HLMP-0301 from Broadcom be used as a direct replacement for the Everlight HLMP0301?

A: Yes. The Broadcom HLMP-0301 maintains identical mechanical dimensions (8.00mm height, rectangular lens 7.31mm x 2.35mm), identical mounting type (through-hole radial), and compatible electrical characteristics (1.9V forward voltage versus 2.1V original, 20mA test current, 100° viewing angle, 635nm peak wavelength). The 0.2V forward voltage difference is within standard LED circuit tolerance ranges.

Q: What is the primary difference between the three substitute options?

A: The Broadcom HLMP-0301 provides the closest mechanical match with nearly identical lens dimensions. The Lumex SSL-LX25783ID offers a narrower viewing angle (80° versus 100°) but maintains compatible dimensions and electrical operation. The Everlight EALP03RRARA0 differs in lens size and height, and delivers significantly higher luminous intensity (50mcd versus 5mcd), requiring circuit evaluation for brightness compatibility.

Q: Are all substitute parts through-hole mounted?

A: Yes. All three substitute parts are through-hole mounted with radial package configuration, maintaining compatibility with existing PCB designs that accommodate the original HLMP0301.

Q: Do the substitute parts meet environmental compliance requirements?

A: All substitute parts carry ROHS3 compliance certification and REACH Unaffected status, matching the environmental compliance profile of the original HLMP0301. All parts have Moisture Sensitivity Level 1 (Unlimited).

Q: What forward voltage range should be considered for circuit design compatibility?

A: The substitute parts operate within a 1.9V to 2.1V forward voltage range at 20mA test current. Standard LED indication circuits designed for the original 2.1V specification will operate within acceptable tolerance with the 1.9V to 2.0V substitute parts. Circuit current limiting resistor values may require minor adjustment based on specific power supply voltage and desired brightness levels.

Q: How do the millicandela ratings affect substitution decisions?

A: The original HLMP0301 delivers 5mcd. The Broadcom HLMP-0301 delivers 2.1mcd (lower brightness), the Lumex SSL-LX25783ID delivers 9mcd (moderate increase), and the Everlight EALP03RRARA0 delivers 50mcd (significant increase). Application brightness requirements determine which substitute is appropriate. Lower brightness may require circuit evaluation for visibility; higher brightness may require current limiting adjustment.

Q: Are there mechanical constraints with the EALP03RRARA0 substitute?

A: Yes. The EALP03RRARA0 has a maximum height of 7.41mm (versus 8.00mm original) and lens dimensions of 5.71mm x 3.17mm (versus 7.24mm x 2.42mm original). These dimensional differences require verification against PCB layout, component spacing, and mechanical clearance requirements before implementation.

Q: What is the viewing angle significance for these LED substitutes?

A: The original HLMP0301 has a 100° viewing angle. The Broadcom HLMP-0301 maintains 100°, the Lumex SSL-LX25783ID has 80° (narrower), and the Everlight EALP03RRARA0 has 110° (wider). Viewing angle affects the angular range over which the LED maintains specified brightness. Applications requiring wide-angle visibility should avoid the Lumex option; applications with directional viewing requirements may benefit from the narrower Lumex angle.
