Key Parameters

Substitute Part Grouping Explanation

Substitution of solar cell components is determined by the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Maximum power output (watts)
• Current at maximum power point (Pmpp)
• Voltage at maximum power point (Pmpp)
• Open circuit voltage (Voc)
• Physical dimensions (length, width, height)
• Solar cell technology type (amorphous, monocrystalline, polycrystalline)
• Moisture sensitivity level and environmental compliance

The substitute part 313070003 represents a different solar cell technology (monocrystalline versus amorphous) with higher power output (2 W versus 1.25 W) and different electrical characteristics. This part is listed as an available alternative based on the manufacturer's substitution data, though the technology transition and performance parameters differ significantly from the original component.

Engineering Selection Recommendations

For applications requiring direct replacement of Seeed 114990246:

The obsolete status of part 114990246 necessitates evaluation of available alternatives. The substitute part 313070003 is currently in active production status with confirmed inventory availability (755 pieces). However, the following engineering considerations apply:

Electrical Differences: The substitute part 313070003 operates at significantly higher voltage (8.2 V open circuit versus 1.7 V) and lower current (360 mA at Pmpp versus 950 mA). Maximum power output is higher (2 W versus 1.25 W). These differences require circuit redesign in voltage regulation and power conditioning stages.

Technology Transition: The shift from amorphous to monocrystalline technology introduces different performance characteristics under varying light conditions and temperature ranges. Monocrystalline cells typically exhibit higher efficiency but different spectral response.

Physical Compatibility: Dimensional differences (205 × 90 × 1 mm versus 180 × 80 × 2.5 mm) require mechanical redesign of mounting and integration structures.

Compliance Status: Both parts maintain MSL 1 (Unlimited) moisture sensitivity rating and share identical ECCN and HTSUS classifications, ensuring regulatory consistency.

Frequently Asked Questions (FAQ)

Q: Can Seeed 313070003 be used as a direct drop-in replacement for 114990246?

A: No. While both are solar cells manufactured by Seeed Technology Co., Ltd, the 313070003 differs in technology type, electrical output characteristics, and physical dimensions. Circuit redesign is required to accommodate the higher voltage output (8.2 V versus 1.7 V open circuit) and different current characteristics.

Q: What are the key electrical differences between these parts?

A: The main part (114990246) delivers 1.25 W at 1.3 V with 950 mA current at maximum power point. The substitute (313070003) delivers 2 W at 5.5 V with 360 mA current at maximum power point. The substitute provides higher power and voltage but lower current.

Q: Are there physical compatibility issues?

A: Yes. The original part measures 205 × 90 × 1 mm, while the substitute measures 180 × 80 × 2.5 mm. Mounting structures and mechanical integration must be redesigned to accommodate these dimensional changes.

Q: What is the technology difference between amorphous and monocrystalline solar cells?

A: The original part uses amorphous silicon technology, while the substitute uses monocrystalline technology. This affects efficiency, spectral response, and performance under different lighting conditions. Monocrystalline cells typically provide higher efficiency but may have different temperature coefficients.

Q: Are both parts compliant with the same regulatory standards?

A: Yes. Both parts share identical ECCN (EAR99) and HTSUS (8541.43.0080) classifications and maintain MSL 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent regulatory compliance.

Q: What should be verified before implementing the substitute part?

A: Verify that the circuit design can accommodate the higher voltage output (8.2 V), lower current output (360 mA), and increased power rating (2 W). Confirm mechanical mounting compatibility with the different dimensions. Evaluate performance requirements under the specific lighting and temperature conditions of the application.
