Adafruit Industries LLC 1379 Addressable LED Discrete Serial RGB

Part Overview

The Adafruit 1379 is an addressable lighting component featuring 10 discrete LEDs with serial (shift register) control interface, supporting Red, Green, Blue (RGB) color output. This component utilizes WS2812 LED technology in a 5.00mm × 5.00mm surface mount package with MSL 1 rating.

The 1379 is classified as Obsolete. Locating equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs and ongoing support.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Adafruit 1379 are identified based on the following critical parameters that determine functional and mechanical compatibility:

• LED Count: 10 LEDs (exact match required)
• Color Output: Red, Green, Blue (RGB) (exact match required)
• Interface Type: Serial (Shift Register) (exact match required)
• Configuration: Discrete (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Physical Dimensions: 5.00mm L × 5.00mm W (exact match required)
• LED Technology: WS2812 or compatible alternatives (SK6812 acceptable)

The Adafruit 1655 meets all substitution criteria as an active product with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The Adafruit 1655 is the direct substitute for the obsolete Adafruit 1379. Both components share identical electrical and mechanical specifications: 10 discrete RGB LEDs, serial shift register interface, 5.00mm × 5.00mm surface mount package, and WS2812 LED technology.

The 1655 is classified as Active product status, ensuring ongoing availability and supply chain continuity. The 1655 carries ROHS3 compliance certification, meeting current environmental and regulatory requirements. The MSL rating difference (1 versus 5A) reflects updated moisture handling specifications for the active product line but does not affect functional compatibility in standard operating environments.

Both components share identical ECCN classification (EAR99), confirming equivalent export control status.

Frequently Asked Questions (FAQ)

Q: Can the Adafruit 1655 directly replace the Adafruit 1379 in existing designs?

A: Yes. The 1655 provides direct functional and mechanical substitution. Both components feature 10 discrete RGB LEDs with serial shift register interface in identical 5.00mm × 5.00mm surface mount packages. Pin configuration and electrical interface remain unchanged.

Q: What is the difference in LED technology between the two parts?

A: The 1379 utilizes WS2812 LEDs. The 1655 supports both SK6812 and WS2812 LED variants. This flexibility in the 1655 does not affect compatibility with existing firmware or control logic designed for WS2812 operation.

Q: Why does the MSL rating differ between the two parts?

A: The 1379 carries MSL 1 (Unlimited moisture exposure tolerance), while the 1655 carries MSL 5A (24-hour moisture exposure tolerance). This reflects updated manufacturing and storage specifications for the active product line. Standard PCB assembly and storage practices remain compatible with both ratings.

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

A: The 1655 carries ROHS3 compliance certification. Both components share identical ECCN classification (EAR99). The 1655 represents the current compliant product offering for new designs and production.

Q: What packaging format is the 1655 supplied in?

A: The 1655 is supplied in Strip packaging, compared to the 1379 which used standard packaging. Strip packaging maintains component integrity and facilitates automated assembly processes.
