Adafruit 3054 Addressable LED Matrix - Equivalent & Substitute Parts

Part Overview

The Adafruit 3054 is a 512-LED (16 x 32) addressable matrix with SPI interface, featuring green and red color output. This product is classified as obsolete, making identification of suitable substitute components essential for ongoing design requirements or production continuity. The matrix configuration and SPI control interface define the primary functional parameters for substitution evaluation.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Adafruit 3054 is evaluated based on the following critical parameters:

• Matrix Configuration: Both main and substitute parts must maintain a matrix-based LED arrangement
• LED Count: 512 LEDs in 16 x 32 configuration
• Color Capability: The substitute must support the required color output
• Mounting Type: User-defined mounting compatibility
• Regulatory Compliance: ECCN and HTSUS classification alignment
• Moisture Sensitivity: MSL 1 rating for storage and handling

The Adafruit 420 qualifies as a substitute based on matching matrix configuration, identical LED count (512 / 16 x 32), user-defined mounting type, and equivalent regulatory classification. The primary difference is expanded color capability (RGB versus green/red) and alternative controller implementation (74HC595 versus HT1632).

Parameter Comparison

Engineering Selection Recommendations

The Adafruit 420 is the identified substitute for the obsolete Adafruit 3054. Selection is based on:

• Product Status: The 420 maintains active production status, ensuring availability and supply chain continuity
• Regulatory Alignment: Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications
• Compliance: The 420 carries ROHS3 certification, meeting current environmental compliance requirements
• Functional Equivalence: Identical matrix configuration and LED count (512 / 16 x 32) with user-defined mounting compatibility

The controller type difference (HT1632 to 74HC595) and expanded color capability (RGB versus green/red) represent design variations that require interface and firmware evaluation during implementation.

Frequently Asked Questions (FAQ)

Q: Can the Adafruit 420 directly replace the 3054 without design modifications?

A: The 420 matches the critical matrix parameters (512 LEDs, 16 x 32 configuration, user-defined mounting). However, the controller type change (HT1632 to 74HC595) and interface differences require firmware and control circuit evaluation.

Q: What is the primary reason for substitution?

A: The Adafruit 3054 is classified as obsolete. The 420 provides functional equivalence with active production status and current regulatory compliance (ROHS3).

Q: Are there differences in physical dimensions?

A: The 420 specifies dimensions of 192.00mm L x 96.00mm W. The 3054 does not provide dimensional specifications in the available data.

Q: Does the RGB capability of the 420 affect substitution suitability?

A: The expanded color output (RGB versus green/red) represents an enhancement. Applications requiring only green and red output can utilize the 420 without functional limitation.

Q: What is the moisture sensitivity rating for both parts?

A: Both the 3054 and 420 carry MSL 1 (Unlimited) rating, indicating equivalent storage and handling requirements.

Q: Are packaging differences significant?

A: The 3054 packaging is listed as "-" (not specified). The 420 is supplied in Bulk packaging. Packaging selection should be confirmed based on application requirements.
