Engineering Selection Recommendations

The C430C474M5U5TA7200 from KEMET is a direct functional and mechanical equivalent to the obsolete P30U474M5. Selection of this substitute is based on the following engineering factors:

Product Status Alignment: The P30U474M5 is classified as obsolete, creating supply chain risk. The C430C474M5U5TA7200 maintains active production status with 55,393 pieces in current inventory, ensuring long-term availability.

Regulatory Compliance: Both components maintain ROHS3 compliance. The KEMET substitute carries EAR99 ECCN classification and REACH Unaffected status, confirming regulatory alignment for international applications.

Electrical Equivalence: All critical electrical parameters—capacitance, voltage rating, tolerance, and temperature coefficient—are identical between the original and substitute part. The Z5U temperature coefficient and 10°C ~ 85°C operating range are preserved.

Mechanical Compatibility: Physical dimensions, lead configuration, and through-hole mounting type are identical, enabling direct PCB-level substitution without layout modifications.

Series Designation: The KEMET part belongs to the AxiMax 400 Comm Z5U series, which is engineered for general-purpose applications matching the original component's intended use.

Frequently Asked Questions (FAQ)

Q: Can the C430C474M5U5TA7200 be used as a direct replacement for P30U474M5 on existing PCBs?

A: Yes. The substitute part matches all critical electrical and mechanical parameters, including capacitance (0.47 µF), voltage rating (50V), tolerance (±20%), temperature coefficient (Z5U), physical dimensions (0.150" Dia x 0.290" L), and lead configuration (straight axial). No PCB modifications are required.

Q: What is the significance of the Z5U temperature coefficient?

A: Z5U designates a ceramic capacitor with a temperature coefficient range of +22% to −56% across the operating temperature span of 10°C to 85°C. This specification must be matched exactly for applications requiring predictable capacitance stability across temperature variations. Both the original and substitute part maintain this specification.

Q: Why is the P30U474M5 obsolete while the KEMET substitute remains active?

A: Product obsolescence reflects manufacturing discontinuation by the original supplier (CDE). The KEMET C430C474M5U5TA7200 represents an active equivalent from a different manufacturer, engineered to the same electrical and mechanical specifications. Active status ensures continued availability for production and field replacement applications.

Q: Are there any compliance differences between the two parts?

A: Both parts are ROHS3 compliant. The KEMET substitute carries additional regulatory designations: EAR99 ECCN classification and REACH Unaffected status. These designations confirm suitability for international distribution and use without additional compliance barriers.

Q: What packaging format is the KEMET substitute supplied in?

A: The C430C474M5U5TA7200 is supplied in Cut Tape (CT) packaging. This format is standard for through-hole axial components and is compatible with conventional component handling and insertion processes.

Q: Must the operating temperature range be exactly 10°C ~ 85°C?

A: The operating temperature range of 10°C ~ 85°C is a critical specification for Z5U ceramic capacitors. Both the original and substitute part meet this requirement exactly. Applications requiring different temperature ranges would require alternative component selection.
