Adafruit 2555 Addressable LED Serial RGB 2M - Equivalent & Substitute Parts

Part Overview

The Adafruit 2555 is an addressable lighting strip featuring 96 LEDs in a serial Red, Green, Blue (RGB) configuration with a total length of 2000mm. This component is classified as obsolete, making identification of compatible substitute parts essential for ongoing system design and maintenance. The serial interface architecture and RGB color capability define the functional requirements for equivalent components.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Adafruit 2555 is determined by the following core parameters:

• Interface Type: Serial protocol compatibility is mandatory for direct substitution
• Color Configuration: RGB (Red, Green, Blue) capability must be maintained
• Manufacturer Consistency: Adafruit Industries LLC components ensure protocol and pinout alignment
• Moisture Sensitivity Level: MSL 1 rating provides equivalent environmental tolerance

The identified substitute part (Adafruit 1948) shares the same interface protocol, RGB color architecture, and manufacturer origin. However, the 1948 differs in LED count (48 vs. 96) and physical length (1000mm vs. 2000mm), classifying it as a functionally compatible but dimensionally scaled alternative rather than a direct 1:1 replacement.

Parameter Comparison

Engineering Selection Recommendations

The Adafruit 1948 is the identified substitute for the obsolete Adafruit 2555. Both components maintain serial interface protocol compatibility and RGB color capability, ensuring functional interoperability at the control level.

Product Status Consideration: The 2555 is obsolete while the 1948 is active, making the 1948 the preferred selection for new designs and ongoing procurement.

Compliance Alignment: Both parts carry identical Moisture Sensitivity Level (MSL) ratings and ECCN/HTSUS classifications, ensuring equivalent environmental and regulatory compliance.

Dimensional Scaling: The 1948 provides 50% of the LED count and physical length of the 2555. System designs requiring the full 96-LED, 2000mm configuration must account for this reduction through multiple unit deployment or alternative sourcing strategies.

Frequently Asked Questions (FAQ)

Q: Can the Adafruit 1948 directly replace the Adafruit 2555 in existing designs?

A: The 1948 is functionally compatible at the protocol level due to shared serial interface and RGB architecture. However, it provides 50% of the LED count and physical length, requiring design modification if full 2000mm coverage is required.

Q: What are the critical parameters for substitution between these parts?

A: Serial interface type, RGB color configuration, and Adafruit Industries LLC manufacturer origin are the determining factors. Both parts meet these criteria.

Q: Are there packaging differences between the 2555 and 1948?

A: The 2555 is specified as user-defined packaging, while the 1948 is supplied in bulk packaging. This distinction affects handling and integration procedures but does not impact electrical or protocol compatibility.

Q: Do both parts have the same environmental tolerance?

A: Yes. Both the 2555 and 1948 carry MSL 1 (Unlimited) ratings, indicating equivalent moisture sensitivity and environmental performance characteristics.

Q: Why is the 2555 listed as obsolete?

A: Obsolescence status indicates the part is no longer in active production. The 1948 represents the current active alternative within the Adafruit addressable LED product line.
