LN482YPX Equivalent & Substitute Parts

Part Overview

The LN482YPX is an amber LED indicator manufactured by Panasonic Electronic Components, designed for through-hole mounting applications. This 2mm radial LED operates at 2.2V forward voltage with a 20mA test current and delivers 2mcd luminous intensity at a peak wavelength of 590nm. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing design support, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LN482YPX are identified based on the following critical parameters that determine functional compatibility:

• Color and Wavelength: Amber color with 590nm peak wavelength ensures consistent optical performance and visual indication matching
• Forward Voltage (Vf): 2.2V typical operating voltage maintains circuit compatibility without requiring redesign
• Test Current: 20mA test current establishes the baseline for luminous intensity specifications
• Mounting Type: Through-hole radial configuration ensures mechanical compatibility with existing PCB layouts
• Package Classification: Radial package type preserves footprint and lead configuration

The LN438YPH qualifies as a substitute based on matching these core parameters while offering an active product status alternative.

Parameter Comparison

Engineering Selection Recommendations

The LN438YPH serves as the primary substitute for the obsolete LN482YPX based on electrical parameter alignment and active product status. Both components share identical forward voltage (2.2V), test current (20mA), and peak wavelength (590nm), ensuring direct circuit compatibility without modification.

The LN438YPH is currently in active production with RoHS compliance certification, providing long-term supply chain stability compared to the obsolete LN482YPX. The increased millicandela rating (3mcd versus 2mcd) and larger lens size (3mm T-1 versus 2mm) represent design improvements that enhance visibility while maintaining the same electrical operating parameters.

Physical form factor differences require verification: the LN438YPH maximum height of 10.85mm exceeds the LN482YPX height of 7.90mm by 2.95mm. PCB layout clearance must be confirmed before implementation to ensure no mechanical interference with adjacent components or enclosure constraints.

Frequently Asked Questions (FAQ)

Q: Can the LN438YPH be used as a direct replacement for the LN482YPX without circuit modification?

A: Yes. Both components operate at identical forward voltage (2.2V) and test current (20mA), eliminating the need for circuit redesign. The electrical interface remains unchanged.

Q: What are the key differences between these two parts?

A: The primary differences are physical form factor and luminous intensity. The LN438YPH features a larger 3mm lens (versus 2mm), higher brightness at 3mcd (versus 2mcd), and greater maximum height at 10.85mm (versus 7.90mm). Electrical parameters remain identical.

Q: Does the larger lens size of the LN438YPH affect compatibility?

A: The larger lens size may impact PCB layout compatibility. The increased height of 2.95mm must be verified against available clearance in the application. If space constraints exist, alternative solutions may be required.

Q: Is the LN438YPH RoHS compliant?

A: Yes, the LN438YPH is RoHS compliant. The LN482YPX RoHS status is not specified in available documentation.

Q: Why is the LN482YPX obsolete?

A: The LN482YPX is classified as obsolete by Panasonic Electronic Components. The LN438YPH represents the active product line continuation with improved specifications and compliance certifications.

Q: Can I use the LN438YPH in applications requiring the exact 2mm lens size?

A: No. The LN438YPH uses a 3mm T-1 lens form factor. If the 2mm lens size is a critical design requirement, alternative amber LED options from the Panasonic product line must be evaluated.
