Engineering Selection Recommendations

The KGM21AV51C475ZU from KYOCERA AVX is a direct electrical and mechanical equivalent to the obsolete CL21F475ZOFNNNG. Selection of this substitute part is supported by the following factors:

Compliance Alignment: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in applications subject to environmental standards.

Product Status: The substitute part maintains active production status, providing supply chain stability and long-term availability compared to the obsolete original part.

Dimensional Compatibility: Physical dimensions remain within acceptable tolerances for 0805 footprint applications. The thickness variance (1.35mm to 1.45mm maximum) remains within standard PCB assembly clearance specifications for surface-mount components.

Electrical Performance: Identical capacitance, voltage rating, tolerance, and temperature coefficient specifications ensure functional equivalence in circuit operation.

Packaging Consideration: The substitute part is supplied in Tape & Reel (TR) format, standard for automated assembly processes, whereas the original part packaging specification was not provided. This represents an improvement in manufacturing efficiency.

Frequently Asked Questions (FAQ)

Q: Can KGM21AV51C475ZU be used as a direct replacement for CL21F475ZOFNNNG without circuit modification?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters. No circuit design changes are required for substitution.

Q: What is the significance of the Y5V temperature coefficient designation?

A: Y5V indicates a temperature coefficient range of -82% to +22% of the nominal capacitance value across the operating temperature range of -30°C to 85°C. This specification is identical between both parts and must be maintained for circuit performance.

Q: Are there dimensional concerns with the thickness difference (1.35mm vs 1.45mm)?

A: No. The 0.10mm thickness variance falls within standard PCB assembly tolerances for 0805 components and does not affect board-level compatibility or clearance requirements.

Q: Why is the original part classified as obsolete?

A: Product obsolescence is determined by manufacturer discontinuation. The substitute part from KYOCERA AVX maintains active production status and identical specifications, providing continuity for applications requiring this capacitor value and rating.

Q: Does the Tape & Reel packaging of the substitute part affect compatibility?

A: No. Tape & Reel is the standard packaging format for automated surface-mount assembly. This packaging format is compatible with standard pick-and-place equipment and does not affect component electrical or mechanical performance.

Q: Are both parts MSL 1 rated?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling. Standard component storage conditions apply.
