LN38GP Equivalent & Substitute Parts

Part Overview

The LN38GP is a green diffused 3mm through-hole LED manufactured by Panasonic Electronic Components, designed for green LED indication applications in discrete 2.2V radial configurations. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. The LN38GP operates at a forward voltage of 2.2V with a test current of 20mA and delivers 3 millicandela of luminous intensity through its diffused round domed lens.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LN38GP is determined by the following critical parameters:

• Color and Wavelength: Green color with peak wavelength of 565nm
• Lens Configuration: 3mm T-1 diffused round domed lens
• Mounting Type: Through-hole radial package
• Electrical Compatibility: Forward voltage range and test current of 20mA
• Physical Dimensions: Maximum height and radial package footprint

The SSL-LX3052GD from Lumex Opto/Components Inc. qualifies as a substitute based on matching color, lens size, lens transparency, mounting type, wavelength, and radial package configuration. Both components operate at compatible forward voltages (2.2V vs. 2V) and identical test current (20mA), with physical dimensions within acceptable tolerance (5.20mm vs. 5.25mm maximum height).

Parameter Comparison

Engineering Selection Recommendations

The SSL-LX3052GD is suitable as a substitute for the LN38GP based on the following factors:

Product Status: The LN38GP is obsolete, while the SSL-LX3052GD is active and maintains current production availability with 8104 units in stock.

Compliance: The SSL-LX3052GD is ROHS3 compliant and REACH unaffected, providing regulatory advantages over the RoHS non-compliant LN38GP for new designs and applications subject to environmental regulations.

Electrical Compatibility: Both components operate at compatible forward voltages (2.2V vs. 2V) and identical test current specifications (20mA), ensuring circuit-level compatibility with existing designs.

Physical and Optical Compatibility: Identical lens size (3mm T-1), lens transparency (diffused), color (green), wavelength (565nm), and mounting type (through-hole radial) ensure mechanical and optical interchangeability. Maximum height difference of 0.05mm is within standard PCB layout tolerances.

Luminous Intensity: The SSL-LX3052GD provides 15mcd compared to the LN38GP's 3mcd, delivering increased brightness while maintaining all other functional parameters.

Frequently Asked Questions (FAQ)

Q: Can the SSL-LX3052GD directly replace the LN38GP in existing designs?

A: Yes. Both components share identical lens size (3mm T-1), lens transparency (diffused), color (green), wavelength (565nm), mounting type (through-hole radial), and test current (20mA). Forward voltage compatibility (2.2V vs. 2V) and maximum height tolerance (5.20mm vs. 5.25mm) support direct substitution in circuit designs.

Q: What is the primary difference between these two parts?

A: The SSL-LX3052GD provides higher luminous intensity (15mcd vs. 3mcd) and is ROHS3 compliant with active production status, whereas the LN38GP is obsolete and RoHS non-compliant.

Q: Are there any circuit design considerations when switching from LN38GP to SSL-LX3052GD?

A: The forward voltage difference of 0.2V (2.2V vs. 2V) is negligible for most indicator applications and does not require circuit redesign. The increased brightness of the SSL-LX3052GD may require current-limiting resistor adjustment if visual consistency is critical.

Q: What is the viewing angle of the SSL-LX3052GD?

A: The SSL-LX3052GD has a viewing angle of 80°. The LN38GP viewing angle is not specified in available documentation.

Q: Are both components available in the same packaging?

A: Both components use radial through-hole packages. The LN38GP is supplied in bulk packaging, while the SSL-LX3052GD is also supplied in bulk packaging, ensuring consistent handling and assembly compatibility.
