HLMP1520 Green LED T-1 Through Hole Equivalent & Substitute Parts

Part Overview

The HLMP1520 is an active green LED indicator manufactured by Everlight Electronics Co Ltd, designed for discrete indication applications in through-hole mounting configurations. This T-1 form factor LED operates at 2.1V forward voltage with a 12mcd brightness rating and 565nm peak wavelength. The component is ROHS3 compliant and carries unlimited moisture sensitivity rating (MSL 1), making it suitable for standard industrial and commercial applications. Equivalent and substitute parts are identified to support design flexibility, inventory management, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HLMP1520 are qualified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Color: Green
• Lens Transparency: Clear
• Mounting Type: Through Hole
• Voltage - Forward (Vf) Typical: 2.1V
• Viewing Angle: 45°
• Wavelength - Peak: 565nm
• Package / Case: Radial
• Lens Style: Round with Domed Top
• Product Status: Active
• RoHS Status: ROHS3 Compliant

Secondary Variation Parameters (Allowable Differences):

• Millicandela Rating: Brightness variations within the green LED category
• Current - Test: Operating current differences
• Lens Size: Minor dimensional variations (2.90mm to 3mm)
• Height Maximum: Acceptable height tolerance range
• Manufacturer: Different qualified manufacturers

The substitute parts 5219430F and HLMP-1521 maintain all primary compatibility criteria while exhibiting variations in brightness rating and test current, which are acceptable substitution parameters for this product category.

Parameter Comparison

Engineering Selection Recommendations

HLMP1520 (Everlight Electronics Co Ltd) Primary specification for applications requiring 12mcd brightness at 20mA test current. Active product status with ROHS3 compliance and unlimited moisture sensitivity rating. Suitable for standard green LED indication circuits with specified brightness requirements.

5219430F (Dialight, Series 521) Higher brightness alternative at 50mcd with reduced test current of 10mA. Lens size 2.90mm represents minor dimensional variation from standard 3mm T-1 form factor. Height maximum of 5.89mm provides compact profile option. Active product status with ROHS3 compliance and REACH unaffected designation. Selection appropriate for applications requiring increased brightness output or lower operating current.

HLMP-1521 (Broadcom Limited, Series HLMP-152x) Intermediate brightness option at 22mcd with 10mA test current. Maintains standard 3mm T-1 lens size and 6.35mm height maximum. Wavelength dominant specification of 569nm with 565nm peak wavelength. Active product status with ROHS3 compliance and REACH unaffected designation. Selection appropriate for applications requiring moderate brightness increase with reduced operating current.

All three parts maintain identical forward voltage (2.1V), viewing angle (45°), and peak wavelength (565nm) specifications, confirming electrical and optical compatibility within the green LED indication category.

Frequently Asked Questions (FAQ)

Q: Can HLMP1520 be directly replaced with 5219430F? A: Direct replacement is supported from an electrical and optical standpoint. Both parts operate at 2.1V forward voltage with 45° viewing angle and 565nm peak wavelength. The 5219430F provides higher brightness (50mcd vs 12mcd) and operates at lower test current (10mA vs 20mA). Lens size difference (2.90mm vs 3mm) and height difference (5.89mm vs 6.30mm) must be evaluated for mechanical fit in the specific application.

Q: What is the brightness difference between substitute parts? A: HLMP1520 provides 12mcd, HLMP-1521 provides 22mcd, and 5219430F provides 50mcd. Selection depends on application visibility requirements. Higher brightness ratings do not affect electrical compatibility but may alter visual perception in the end application.

Q: Are all substitute parts ROHS3 compliant? A: Yes. HLMP1520, 5219430F, and HLMP-1521 are all ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating, confirming environmental and regulatory compatibility.

Q: Does the test current difference affect circuit design? A: HLMP1520 specifies 20mA test current, while 5219430F and HLMP-1521 specify 10mA test current. These are characterization parameters. Actual circuit design must be based on application requirements and forward voltage specification (2.1V for all parts). Current-limiting resistor selection should be based on desired operating point, not test current specification.

Q: Can lens size variation affect mechanical compatibility? A: Lens size differences (2.90mm for 5219430F vs 3mm for HLMP1520 and HLMP-1521) may affect fit in lens holders, bezels, or mechanical assemblies designed for specific T-1 dimensions. Height variations (5.89mm to 6.35mm) must be evaluated for PCB clearance and mechanical constraints in the target application.

Q: Are all parts available in active production status? A: Yes. HLMP1520, 5219430F, and HLMP-1521 are all listed as active products, confirming ongoing manufacturing and supply availability.
