Engineering Selection Recommendations

The KEMET C0805C331K5RAC7800 is the direct functional equivalent for the obsolete CDE C0805C331K5RAC. Selection is based on the following engineering criteria:

Electrical Equivalence: Both parts maintain identical capacitance (330 pF), tolerance (±10%), voltage rating (50V), and temperature coefficient (X7R) specifications. The operating temperature range of -55°C to 125°C is fully supported by both components.

Mechanical Compatibility: Both parts utilize the 0805 (2012 Metric) surface mount package with identical footprint dimensions (0.079" L x 0.049" W). The KEMET substitute features a reduced maximum thickness of 0.035" compared to the CDE original at 0.051", which presents no compatibility issues for standard PCB assembly processes.

Regulatory Compliance: Both parts are ROHS3 compliant and carry MSL 1 rating, ensuring equivalent handling, storage, and environmental compliance requirements.

Availability: The KEMET part is currently active in production with substantial inventory availability (61,700 pcs), ensuring reliable procurement for ongoing and future applications.

Frequently Asked Questions (FAQ)

Q: Can the KEMET C0805C331K5RAC7800 be used as a direct replacement for the CDE C0805C331K5RAC?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical capacitance (330 pF), tolerance (±10%), voltage rating (50V), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), and 0805 package footprint. No circuit modifications or PCB layout changes are required.

Q: What is the significance of the thickness difference between the two parts?

A: The KEMET substitute has a maximum thickness of 0.035" (0.88mm) compared to the CDE original at 0.051" (1.30mm). This reduced thickness does not affect electrical performance or PCB compatibility. Standard surface mount assembly processes accommodate both dimensions without modification.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are ROHS3 compliant and carry identical Moisture Sensitivity Level 1 (MSL 1) ratings. No compliance or certification differences exist that would affect substitution suitability.

Q: Why is the CDE part listed as obsolete?

A: Product obsolescence reflects manufacturer discontinuation decisions. The KEMET equivalent remains in active production, providing a viable path for continued component procurement and design continuity.

Q: Does the packaging format affect substitution?

A: The CDE part is specified without packaging detail in the provided data. The KEMET substitute is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly. This packaging format is compatible with automated pick-and-place equipment used in modern PCB manufacturing.

Q: Are there any application-specific considerations for substitution?

A: The CDE original is designated for general-purpose applications, while the KEMET substitute is specified for bypass and decoupling applications. Both designations are compatible with the same electrical specifications and operating parameters, confirming functional equivalence across application categories.
