Adafruit Industries LLC Part 315 - RGB LED Equivalent & Substitute Parts

Part Overview

The Adafruit Part 315 is a common anode RGB LED with a 5mm round diffused lens, designed for through-hole mounting in electronic assemblies requiring red, green, and blue light indication. This component features a square lens with domed top and operates at forward voltages of 2.1V (red), 3.8V (green), and 2.7V (blue) with a test current of 20mA across all color channels.

The Part 315 carries an obsolete product status. Identifying equivalent substitute parts ensures design continuity and maintains supply chain reliability for applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Part 315 is determined by the following critical parameters:

• Color Configuration: Must be Red, Green, Blue (RGB)
• Configuration Type: Must be Common Anode
• Package / Case: Must be 4-DIP (0.200", 5.08mm)
• Mounting Type: Must be Through Hole
• Lens Size: Must be 5.00mm
• Lens Transparency: Must be Diffused
• RoHS Compliance: Must maintain ROHS3 Compliant status

The substitute part must maintain electrical compatibility within the forward voltage and test current specifications while preserving the mechanical form factor and mounting interface. Variations in millicandela ratings, lens style geometry, and wavelength characteristics are permissible provided the core functional parameters remain within acceptable operating ranges.

Parameter Comparison

Engineering Selection Recommendations

Part 1451 qualifies as a direct substitute for Part 315 based on matching core electrical and mechanical parameters. Both components maintain ROHS3 compliance, identical package configuration (4-DIP 0.200"), and equivalent test current specifications (20mA across all color channels).

Part 1451 carries an active product status, ensuring ongoing availability and supply chain continuity compared to the obsolete Part 315. The forward voltage specifications for Part 1451 are lower across all color channels (1.8V red vs. 2.1V, 3V green vs. 3.8V, 3V blue vs. 2.7V), which may reduce power consumption in existing circuit designs without requiring circuit modification due to the common anode configuration and standard current-limiting resistor approach.

The substitute part exhibits a wider viewing angle (90° versus 80°) and increased millicandela ratings (800mcd red, 1500mcd green, 700mcd blue versus 400mcd red, 1200mcd green, 400mcd blue), providing enhanced brightness and visibility characteristics. The reduced maximum height (5.20mm versus 10.10mm) may affect mechanical clearance in space-constrained applications.

Both components maintain identical moisture sensitivity levels and export classification codes, supporting seamless integration into existing supply chain and compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can Part 1451 be used as a direct replacement for Part 315 in existing designs?

A: Yes. Part 1451 maintains the same common anode configuration, 4-DIP package, 5mm lens size, and 20mA test current specifications. The electrical interface remains compatible with existing circuit designs utilizing current-limiting resistors for each color channel.

Q: What are the key differences between Part 315 and Part 1451?

A: The primary differences are forward voltage specifications (lower on Part 1451), millicandela ratings (higher on Part 1451), viewing angle (90° versus 80°), and maximum height (5.20mm versus 10.10mm). Part 1451 carries an active product status while Part 315 is obsolete.

Q: Will the lower forward voltages of Part 1451 affect circuit operation?

A: No. The lower forward voltages reduce power consumption but do not affect circuit compatibility. Standard current-limiting resistor calculations will yield slightly lower resistor values for equivalent brightness, but existing resistor values will continue to operate within acceptable parameters.

Q: Are there mechanical clearance considerations when substituting Part 1451 for Part 315?

A: Yes. Part 1451 has a maximum height of 5.20mm compared to Part 315 at 10.10mm. Verify that the reduced height does not create mechanical interference or visibility issues in the target application. The horizontal dimensions (7.62mm L x 7.62mm W) remain identical.

Q: Do both parts maintain the same compliance certifications?

A: Yes. Both Part 315 and Part 1451 are ROHS3 compliant, carry MSL Level 1 (Unlimited), and share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.
