Adafruit 2556 Addressable LED Serial RGB 1M - Equivalent & Substitute Parts

Part Overview

The Adafruit 2556 is an addressable lighting component featuring 48 LEDs in a serial Red, Green, Blue (RGB) configuration with a 1000mm length. This product is classified as Obsolete, making identification of suitable substitute components essential for ongoing system design and procurement.

The 2556 provides serial interface control for individual LED addressing across its 48-unit array. Due to its obsolete status, equivalent alternatives must maintain functional parity in LED count, color configuration, interface protocol, and physical dimensions to ensure direct system compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Adafruit 2556 is determined by the following critical parameters:

• LED Count: 48 LEDs (exact match required)
• Color Configuration: Red, Green, Blue (RGB) (exact match required)
• Interface Protocol: Serial (exact match required)
• Physical Length: 1000.00mm (exact match required)
• Manufacturer: Adafruit Industries LLC (same manufacturer preferred for consistency)

The substitute part Adafruit 1948 meets all mandatory substitution criteria. The primary distinction is the Configuration designation (Strip vs. unspecified in the original), which represents a form factor clarification rather than a functional deviation. Both components deliver identical electrical and optical performance characteristics.

Engineering Selection Recommendations

The Adafruit 1948 is the direct substitute for the Adafruit 2556. Selection of the 1948 is supported by:

• Product Status Alignment: The 1948 maintains Active status, ensuring continued availability and manufacturing support, whereas the 2556 is Obsolete.
• Regulatory Compliance: Both components share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, confirming equivalent export and tariff treatment.
• RoHS Certification: The 1948 carries explicit ROHS3 Compliant certification, providing enhanced environmental compliance documentation.
• Functional Equivalence: All critical electrical and mechanical parameters are identical, enabling direct substitution without circuit redesign or system reconfiguration.

Frequently Asked Questions (FAQ)

Q: Can the Adafruit 1948 replace the 2556 in existing designs?

A: Yes. The 1948 is functionally equivalent across all critical parameters: 48 LEDs, RGB color configuration, serial interface, and 1000mm length. No design modifications are required.

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

A: The 2556 is classified as Obsolete, while the 1948 is Active. The 1948 also explicitly documents ROHS3 Compliant status. Both deliver identical performance.

Q: Are there any packaging differences?

A: The 1948 is specified with Bulk packaging, whereas the 2556 packaging is listed as unspecified. This represents a procurement and handling distinction only, not a functional difference.

Q: Do both parts use the same serial interface protocol?

A: Yes. Both the 2556 and 1948 utilize serial interface control for LED addressing. No protocol conversion or firmware modification is necessary.

Q: Is the 1948 available in inventory?

A: Yes. The 1948 has 957 pieces listed as New Original In Stock, providing immediate procurement availability.
