Key Parameters

Substitute Part Grouping Explanation

Substitution of the 205QPC250KA3A1CL is determined by the following critical parameters:

Electrical Compatibility:

• Capacitance value must equal 2 µF
• AC voltage rating must be 250V or higher
• Tolerance must accommodate ±10% or tighter specification

Mechanical Compatibility:

• Mounting type must be chassis mount
• Package configuration must be rectangular box
• Physical dimensions must fit within the original installation space
• Termination must be compatible with the circuit connection method

Environmental & Compliance:

• Operating temperature range must support -25°C to 70°C minimum
• RoHS3 compliance required
• Dielectric material must be film-based (polyester or polypropylene acceptable for motor run applications)

The substitute part EEC2E205HQA401 meets these criteria with equivalent electrical ratings and compatible mechanical form factor, though with different dielectric material (polypropylene vs. polyester) and termination style (quick connect vs. push-in spring).

Parameter Comparison

Engineering Selection Recommendations

Electrical Equivalence: The EEC2E205HQA401 provides full electrical equivalence to the 205QPC250KA3A1CL. Both components deliver 2 µF capacitance at 250V AC rating with compatible tolerance specifications for motor run applications. The substitute's tolerance of -5%, +10% is tighter than the original ±10%, ensuring superior performance consistency.

Thermal Performance: The substitute part supports an extended operating temperature range of -25°C to 85°C, exceeding the original specification of -25°C to 70°C. This provides additional thermal margin for applications subject to elevated ambient conditions.

Compliance Status: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements for electronic component procurement and deployment.

Physical Integration: The substitute exhibits a smaller footprint (37.00mm L × 11.50mm W vs. 46.00mm L × 13.00mm W), which may provide installation advantages in space-constrained applications. Height difference is minimal (26.00mm vs. 24.50mm). Termination style differs (quick connect/disconnect vs. push-in spring), requiring verification of circuit connection compatibility before deployment.

Dielectric Material Consideration: The substitute employs polypropylene metallized film instead of polyester. Both materials are suitable for motor run capacitor applications and maintain equivalent electrical performance at the specified voltage and frequency ratings.

Frequently Asked Questions (FAQ)

Q: Can the EEC2E205HQA401 directly replace the 205QPC250KA3A1CL in existing circuits?

A: Electrical substitution is valid. The capacitance, voltage rating, and tolerance specifications are compatible. However, the termination method differs (quick connect vs. push-in spring), requiring physical connection verification before installation.

Q: What is the tolerance difference between these parts, and does it affect motor run performance?

A: The original part specifies ±10% tolerance, while the substitute offers -5%, +10% tolerance. The substitute's tighter tolerance provides improved capacitance consistency. Both tolerances are acceptable for motor run applications.

Q: Are there dimensional constraints that would prevent substitution?

A: The substitute is physically smaller in length and width (37.00mm × 11.50mm vs. 46.00mm × 13.00mm) but slightly taller (26.00mm vs. 24.50mm). Verify available mounting space before selection. The smaller footprint may provide installation advantages in confined spaces.

Q: Does the polypropylene dielectric in the substitute affect reliability compared to the polyester original?

A: Both polyester and polypropylene metallized films are established dielectric materials for motor run capacitors. The substitute's extended temperature rating (-25°C to 85°C vs. -25°C to 70°C) indicates robust thermal performance suitable for motor run duty cycles.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the 205QPC250KA3A1CL and EEC2E205HQA401 are ROHS3 compliant and REACH unaffected, meeting current electronic component procurement requirements.

Q: What is the significance of both parts being classified as obsolete?

A: Obsolete status indicates these components are no longer in active production. Availability is limited to existing inventory. For new designs or long-term production requirements, consultation with component suppliers regarding current-generation alternatives is recommended.
