Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 104990128 is determined by the following critical parameters:

Matrix Configuration: The substitute must maintain an 8 x 32 LED matrix arrangement (256 total LEDs).

LED Type Compatibility: The primary LED type is WS2812 5050-format. Substitutes utilizing WS2812 or functionally equivalent addressable RGB LED types (such as SK6812) are acceptable, as these share identical serial shift register communication protocols and pinout specifications.

Interface Protocol: Serial shift register interface is mandatory. This ensures direct compatibility with existing control circuitry and firmware implementations.

Color Capability: Full RGB (Red, Green, Blue) color output is required.

Regulatory Compliance: ECCN EAR99 and HTSUS 8541.41.0000 classification must be maintained.

The Adafruit Industries LLC model 2294 meets all substitution criteria through equivalent LED count, compatible LED types (SK6812 or WS2812), identical serial shift register interface, and matching regulatory classification.

Parameter Comparison

Engineering Selection Recommendations

The Adafruit Industries LLC model 2294 is the qualified substitute for the obsolete Seeed Technology Co., Ltd model 104990128. Selection of the 2294 is based on the following engineering factors:

Functional Equivalence: Both modules provide identical LED matrix dimensions (8 x 32 configuration, 256 total LEDs) with full RGB addressability through serial shift register control.

LED Type Compatibility: The 2294 accepts both SK6812 and WS2812 LED types. The WS2812 variant ensures direct compatibility with existing firmware and control implementations designed for the 104990128.

Active Product Status: The 2294 maintains active product status with confirmed inventory availability (828 units), ensuring long-term procurement viability and continued manufacturer support.

Regulatory Alignment: Both products share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, eliminating regulatory compliance complications in design transitions.

Physical Dimensions: The 2294 specifies physical dimensions of 320.00mm L x 80.00mm W, providing dimensional reference for mechanical integration planning.

Frequently Asked Questions (FAQ)

Q: Can the Adafruit 2294 directly replace the Seeed 104990128 in existing designs?

A: Yes. Both modules feature identical LED matrix configurations (8 x 32, 256 LEDs), RGB color capability, and serial shift register interface protocols. Existing control firmware and circuit designs require no modification when substituting the 2294 for the 104990128.

Q: What is the significance of the 2294 supporting both SK6812 and WS2812 LED types?

A: The 2294 is manufactured with flexibility to incorporate either SK6812 or WS2812 addressable RGB LEDs. Both LED types implement identical serial communication protocols and pinout specifications. This flexibility ensures consistent performance regardless of which LED variant is present in a specific production batch.

Q: Why is the 104990128 classified as obsolete?

A: Obsolete classification indicates the manufacturer (Seeed Technology Co., Ltd) has discontinued production and no longer maintains active inventory or support for this model. The 2294 provides an active, supported alternative with equivalent functionality.

Q: Are there any packaging differences between the two modules?

A: The 104990128 specifies packaging as "-" (not defined in available documentation). The 2294 is packaged in Bulk format. Both modules are user-defined mounting type, allowing integration into custom mechanical assemblies.

Q: Do both modules meet the same regulatory requirements?

A: Yes. Both the 104990128 and 2294 are classified under ECCN EAR99 and HTSUS code 8541.41.0000, indicating identical export control and tariff classification status.
