Engineering Selection Recommendations

The C430C474M5U5TA7200 from KEMET is the direct functional equivalent for the obsolete P30U474M5-F. Selection of this substitute is based on the following engineering criteria:

Electrical Equivalence: All electrical specifications match identically, including capacitance, voltage rating, temperature coefficient, and tolerance. The Z5U temperature coefficient ensures equivalent capacitance stability across the 10°C to 85°C operating range.

Mechanical Compatibility: Physical dimensions, axial package configuration, and straight lead style are identical, ensuring direct PCB layout compatibility without design modification.

Regulatory Compliance: Both components maintain ROHS3 compliance status, satisfying modern regulatory requirements for electronic component procurement.

Supply Chain Continuity: The KEMET substitute is classified as active with substantial inventory availability (55,393 pieces), ensuring reliable procurement compared to the discontinued CDE original.

Series Designation: The KEMET part belongs to the AxiMax 400 Comm Z5U series, which is specifically designed for general-purpose applications requiring Z5U temperature stability characteristics.

Frequently Asked Questions (FAQ)

Q: Can the C430C474M5U5TA7200 be used as a direct replacement for the P30U474M5-F without PCB modification?

A: Yes. Both components share identical electrical specifications (0.47 µF, 50V, Z5U, ±20% tolerance) and mechanical dimensions (0.150" Dia x 0.290" L axial package with straight leads). Direct substitution on existing PCBs is possible without layout changes.

Q: What does the Z5U temperature coefficient mean for this application?

A: Z5U designates a temperature coefficient range of +22% to -56% capacitance change across the 10°C to 85°C operating temperature range. This specification is identical between the original and substitute parts, ensuring equivalent performance across temperature variations.

Q: Are there any compliance differences between the original and substitute?

A: Both components are ROHS3 compliant. The KEMET substitute additionally carries REACH Unaffected status and EAR99 ECCN classification, providing enhanced regulatory documentation for international applications.

Q: Why is the original P30U474M5-F obsolete?

A: The P30U474M5-F is classified as obsolete because Cornell Dubilier Electronics has discontinued production. The KEMET C430C474M5U5TA7200 remains in active production, providing supply chain continuity for applications requiring this capacitance and voltage rating.

Q: Does packaging format affect the substitution?

A: The original part is available in standard inventory format. The KEMET substitute is supplied in Cut Tape (CT) packaging. Both formats contain identical components; packaging format selection depends on assembly process requirements (bulk handling versus automated tape-fed assembly).

Q: What is the tolerance specification, and does it affect circuit design?

A: Both components carry ±20% tolerance, meaning the actual capacitance value can range from 0.376 µF to 0.564 µF. Circuit designs must account for this tolerance range. The identical tolerance between original and substitute ensures equivalent circuit performance.
