Adafruit Industries LLC 2554 Addressable LED Serial RGB 3M

Part Overview

The Adafruit 2554 is an addressable lighting strip featuring 144 LEDs with serial Red, Green, Blue (RGB) control over a 3000mm length. This product is classified as Obsolete, making identification of suitable alternatives necessary for ongoing system design and component procurement.

The 2554 provides individual LED addressability through a serial interface, enabling dynamic color and brightness control across the entire strip. Its extended 3-meter length and high LED density make it suitable for applications requiring distributed RGB lighting control.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2554 is determined by the following critical parameters:

• Color specification: Red, Green, Blue (RGB) addressable control
• Interface type: Serial communication protocol
• LED count and density: Functional equivalence based on total addressable LEDs
• Physical form factor: Configuration as a continuous strip or coil
• Compliance and certifications: Moisture sensitivity level and regulatory classifications

The identified substitute, Adafruit 1948, shares the core functional characteristics of RGB serial addressability and identical compliance ratings. However, differences in LED count (48 vs. 144) and physical length (1000mm vs. 3000mm) represent trade-offs in application scope rather than functional incompatibility.

Parameter Comparison

Engineering Selection Recommendations

The Adafruit 1948 is an active product with identical compliance certifications (MSL 1, EAR99, HTSUS 8541.41.0000) and matching RGB serial interface architecture. Its Active product status provides ongoing availability and support compared to the Obsolete 2554.

Selection between these parts depends on application-specific requirements:

• LED count requirement: The 1948 provides 48 addressable LEDs versus 144 in the 2554, representing a 67% reduction in total LED count.
• Physical length requirement: The 1948 spans 1000mm compared to the 2554's 3000mm, representing a 67% reduction in strip length.
• Compliance alignment: Both parts maintain identical regulatory classifications and moisture sensitivity ratings, ensuring equivalent environmental performance.

Frequently Asked Questions (FAQ)

Q: Can the 1948 directly replace the 2554 in existing designs?

A: Both parts share identical RGB serial interface specifications and compliance ratings. However, the 1948 contains one-third the LED count and physical length of the 2554. Direct replacement is possible only if the application can accommodate reduced LED density and shorter physical coverage.

Q: Are there differences in serial communication protocols between these parts?

A: Both parts utilize serial interface architecture for RGB addressability. No protocol differences are specified in the provided technical parameters.

Q: What is the significance of the Active versus Obsolete product status?

A: The 2554 is classified as Obsolete, indicating discontinued manufacturing and limited future availability. The 1948 maintains Active status, ensuring ongoing supply and support from Adafruit Industries LLC.

Q: Do both parts have identical moisture sensitivity ratings?

A: Yes. Both the 2554 and 1948 are rated MSL 1 (Unlimited), indicating equivalent moisture handling and storage requirements.

Q: What packaging differences exist between these parts?

A: The 1948 is specified as Bulk packaging. The 2554 packaging specification is not provided in the available technical data.
