Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 104990127 is determined by the following critical parameters:

Configuration Match: Matrix layout with 16 x 16 LED arrangement (256 total LEDs)

Color Specification: Red, Green, Blue (RGB) addressable color output

Interface Compatibility: Serial shift register control protocol

LED Technology: WS2812 or functionally equivalent addressable LED chipsets (SK6812)

Moisture Sensitivity: MSL 1 classification (Unlimited moisture exposure tolerance)

Regulatory Compliance: ECCN EAR99 and HTSUS 8541.41.0000 classification

The substitute part must satisfy all parameters listed above to ensure functional and mechanical compatibility within existing circuit designs and assembly processes.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: Adafruit Industries LLC model 2547 (Neopixel series)

The 2547 satisfies all critical substitution parameters established for the 104990127. Both components feature identical LED matrix configuration (256 LEDs in 16 x 16 arrangement), RGB color capability, and serial shift register interface protocol. The 2547 utilizes SK6812 or WS2812 LED chipsets, maintaining functional compatibility with existing firmware and control logic designed for the original component.

Regulatory and Compliance Status: Both components carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, ensuring equivalent export control and tariff treatment.

Availability Advantage: The 2547 maintains Active product status with documented inventory availability (791 Pcs), whereas the 104990127 is Obsolete. Selection of the 2547 ensures long-term supply chain continuity and eliminates obsolescence risk.

Dimensional Specification: The 2547 provides explicit dimensional data (160.00mm L x 160.00mm W), enabling precise mechanical integration planning. The original 104990127 does not specify dimensions; the Adafruit component's documented size supports design verification.

Frequently Asked Questions (FAQ)

Q: Can the Adafruit 2547 directly replace the Seeed 104990127 in existing designs?

A: Yes. Both components share identical matrix configuration (256 LEDs, 16 x 16), RGB color output, and serial shift register interface. Existing firmware and control circuitry designed for the 104990127 will function with the 2547 without modification.

Q: What is the difference between WS2812 and SK6812 LED chipsets used in the 2547?

A: Both chipsets support serial addressable control via shift register protocol. The 2547 specification indicates compatibility with either chipset. Functional behavior and control timing are equivalent for standard RGB addressable lighting applications.

Q: Does the 2547 meet the same moisture sensitivity requirements as the 104990127?

A: Yes. Both components carry MSL 1 (Unlimited) classification, indicating identical moisture exposure tolerance and storage requirements.

Q: Are there packaging differences between the 104990127 and 2547?

A: The 104990127 packaging is listed as "-" (not specified). The 2547 is supplied in Bulk packaging. Verify bulk packaging format compatibility with your assembly and handling procedures.

Q: What are the export control implications of substituting the 2547?

A: Both components carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. No change in export control or tariff treatment occurs when substituting the 2547 for the 104990127.

Q: Is the 2547 available in the same physical dimensions as the 104990127?

A: The 104990127 does not specify dimensions. The 2547 is documented as 160.00mm L x 160.00mm W. Confirm this dimension is compatible with your mechanical design requirements before final component selection.
