HLMP1385 Equivalent & Substitute Parts Reference

Part Overview

The HLMP1385 is an active red LED indicator designed for through-hole mounting applications. This 3mm diffused lens component operates at 2V forward voltage with a 20mA test current, delivering 11 millicandela luminous intensity. The part is manufactured by Everlight Electronics Co Ltd and maintains ROHS3 compliance with unlimited moisture sensitivity rating (MSL 1). Finding equivalent substitute parts is necessary to ensure supply chain continuity, optimize inventory management, and maintain design flexibility across manufacturing batches and procurement cycles.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HLMP1385 is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Forward voltage (2V), test current (20mA), and millicandela rating (11mcd) must match exactly to ensure proper circuit operation and brightness consistency.

Optical Characteristics: Color (red), lens transparency (diffused), peak wavelength (635nm), viewing angle (60°), and lens style (round with domed top) must be identical to maintain visual indication performance and system integration.

Mechanical Compatibility: Lens size (3mm, T-1), mounting type (through hole), and package configuration (radial) must align precisely to ensure physical fit within PCB layouts and mechanical assemblies.

Regulatory Compliance: RoHS status and moisture sensitivity rating (MSL 1) establish baseline environmental and manufacturing standards for acceptable substitutes.

Only components meeting all specified parameters across these four categories qualify as true equivalents.

Parameter Comparison

Engineering Selection Recommendations

Both the Everlight HLMP1385 and Fairchild Semiconductor HLMP1385 are active products with identical electrical, optical, and mechanical specifications. Selection between these equivalents should be based on the following factors:

Supply Availability: The Fairchild Semiconductor variant maintains higher inventory (6062 units) compared to the Everlight variant (909 units), providing greater supply security for high-volume production requirements.

Regulatory Compliance: Both parts maintain MSL 1 (unlimited moisture sensitivity) and comply with applicable environmental standards. The Everlight variant carries explicit ROHS3 compliance certification. The Fairchild variant lists RoHS status as "Not applicable," which does not indicate non-compliance but rather a different classification methodology.

Packaging Configuration: The Everlight variant is supplied with standard packaging, while the Fairchild variant is available in bulk packaging. Packaging selection depends on procurement workflow and inventory management protocols.

Product Status: Both components maintain active product status, ensuring continued manufacturer support and availability.

Frequently Asked Questions (FAQ)

Q: Can the Fairchild Semiconductor HLMP1385 be used as a direct replacement for the Everlight HLMP1385?

A: Yes. Both parts share identical part numbers and specifications across all critical parameters: 2V forward voltage, 20mA test current, 11mcd brightness, 3mm diffused red lens, 60° viewing angle, through-hole radial mounting, and 635nm peak wavelength. They are parametric equivalents suitable for direct substitution in circuit designs.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by exact equivalence in four categories: (1) Electrical specifications—forward voltage, test current, and millicandela rating; (2) Optical characteristics—color, lens transparency, wavelength, viewing angle, and lens style; (3) Mechanical compatibility—lens size, mounting type, and package configuration; (4) Regulatory compliance—RoHS status and moisture sensitivity rating.

Q: Does the difference in packaging (standard vs. bulk) affect electrical or mechanical performance?

A: No. Packaging type affects only procurement and handling procedures, not component performance. Both standard and bulk packaging contain identical components with identical specifications. Selection depends on manufacturing workflow and inventory management requirements.

Q: Are there any compliance differences between the two manufacturers?

A: The Everlight variant explicitly lists ROHS3 compliance. The Fairchild variant lists RoHS status as "Not applicable." Both parts carry MSL 1 (unlimited) moisture sensitivity rating. Compliance requirements should be verified against specific application and regional regulations.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. Identical through-hole radial mounting, 3mm T-1 lens size, and all electrical specifications ensure mechanical and electrical interchangeability in existing PCB layouts without design modifications.
