Key Parameters

Substitute Part Grouping Explanation

Substitution of the Parallax Inc. 750-00031 is based on the following criteria derived from the provided parameters:

Electrical Compatibility Criteria:

• Maximum power output capacity (1 W nominal range)
• Open circuit voltage (10.4 V nominal range)
• Maximum power point voltage and current (Vmpp and Impp)
• Short circuit current (Isc)

Physical Compatibility Criteria:

• Package type classification (Module or Cells)
• Overall dimensions and form factor
• Mounting and integration compatibility

Regulatory and Compliance Criteria:

• ECCN classification (EAR99)
• REACH compliance status
• Product availability and active manufacturing status

The identified substitute part, Panasonic - BSG AM-7E04CAR-DGK-T, operates within similar power and voltage ranges but differs in solar cell technology type (amorphous versus monocrystalline), physical dimensions, and operating temperature range. These differences must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The Parallax Inc. 750-00031 is classified as obsolete. The Panasonic - BSG AM-7E04CAR-DGK-T maintains active product status with current manufacturing availability, supporting long-term procurement and supply chain continuity.

Regulatory Compliance: Both parts carry identical ECCN classification (EAR99) and maintain equivalent export control status. The Panasonic part is REACH compliant with active product designation, whereas the Parallax part is REACH Unaffected due to obsolete status.

Electrical Parameter Differences: The substitute part delivers 0.801 W maximum power versus 1 W for the original part, representing an 19.9% reduction in power capacity. Open circuit voltage increases from 10.4 V to 12 V. Maximum power point voltage decreases from 9 V to 7.7 V. Current @ Pmpp remains comparable at 104 mA versus 110 mA. These electrical differences require circuit-level evaluation for specific applications.

Physical and Thermal Differences: The substitute part features different dimensions (150 mm L × 110 mm W × 2 mm H versus 135 mm L × 125 mm W) and operates across a narrower temperature range (-10°C to 60°C versus 0°C to 70°C). Package classification differs (Cells versus Module), affecting integration methodology.

Technology Type: The original part uses monocrystalline technology while the substitute uses amorphous technology. This fundamental difference impacts efficiency characteristics, temperature coefficient behavior, and light spectrum response.

Frequently Asked Questions (FAQ)

Q: Can the Panasonic AM-7E04CAR-DGK-T directly replace the Parallax 750-00031 in existing designs?

A: Direct replacement requires circuit-level evaluation. The substitute part differs in maximum power output (0.801 W versus 1 W), open circuit voltage (12 V versus 10.4 V), and maximum power point voltage (7.7 V versus 9 V). Applications with strict power budget requirements or voltage regulation specifications must be reassessed.

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

A: The Parallax part delivers higher maximum power (1 W) and lower open circuit voltage (10.4 V). The Panasonic part provides higher open circuit voltage (12 V) but lower maximum power (0.801 W) and lower maximum power point voltage (7.7 V). Current @ Pmpp values are comparable (110 mA versus 104 mA).

Q: How do the physical dimensions affect substitution?

A: The Parallax part measures 135 mm × 125 mm with Module packaging. The Panasonic part measures 150 mm × 110 mm × 2 mm with Cells packaging. Mechanical fit, mounting structure, and integration approach must be verified for the specific application enclosure and assembly design.

Q: What is the impact of different solar cell technologies?

A: The Parallax part uses monocrystalline technology while the Panasonic part uses amorphous technology. These technologies exhibit different efficiency curves, temperature coefficients, and spectral response characteristics. Application-specific performance under actual operating conditions must be validated.

Q: Are there temperature range compatibility concerns?

A: The Parallax part operates from 0°C to 70°C while the Panasonic part operates from -10°C to 60°C. Applications requiring operation above 60°C or below 0°C may not be compatible with the substitute part.

Q: What is the significance of product status differences?

A: The Parallax part is obsolete with no ongoing manufacturing. The Panasonic part maintains active status with current production availability. For new designs or long-term system support, the active product status provides supply chain reliability and manufacturing continuity.
