Substitute Part Grouping Explanation

Substitution of the obsolete C0603C331K2RAC is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 330 pF (exact match required)
• Tolerance: ±10% (defines acceptable capacitance range)
• Voltage rating: 200V (minimum acceptable rating)
• Temperature coefficient: X7R (ensures stable performance across -55°C to 125°C)

Mechanical Parameters:

• Package designation: 0603 (1608 Metric) (ensures PCB footprint compatibility)
• Mounting type: Surface Mount, MLCC (confirms assembly process compatibility)

Compliance Parameters:

• RoHS3 compliance (regulatory requirement)
• Moisture Sensitivity Level 1 (handling and storage compatibility)

The KEMET C0603C331K2RAC7867 meets all specified parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The KEMET C0603C331K2RAC7867 is the qualified substitute for the obsolete CDE C0603C331K2RAC based on the following factors:

Electrical Equivalence: Both parts specify identical capacitance (330 pF), tolerance (±10%), voltage rating (200V), and temperature coefficient (X7R), ensuring functional interchangeability in circuit applications.

Mechanical Compatibility: Both components utilize the 0603 (1608 Metric) package with surface mount MLCC mounting type. Physical dimensions are equivalent, with the KEMET part featuring a maximum thickness of 0.034" compared to 0.035" for the CDE part, confirming PCB assembly compatibility.

Compliance Alignment: Both parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 rating, satisfying regulatory and handling requirements.

Availability: The KEMET substitute is currently in active production status with substantial inventory availability (11,124 pieces), addressing the obsolescence of the original CDE component.

Frequently Asked Questions (FAQ)

Q: Can the KEMET C0603C331K2RAC7867 be used as a direct replacement for the CDE C0603C331K2RAC?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: 330 pF capacitance, ±10% tolerance, 200V rating, X7R temperature coefficient, and 0603 package. The KEMET part is suitable for direct substitution in existing designs.

Q: Are there any physical differences between these parts?

A: The maximum thickness differs slightly: CDE part is 0.035" (0.90mm) while the KEMET part is 0.034" (0.87mm). This minor difference does not affect PCB assembly or circuit performance.

Q: What is the significance of the X7R temperature coefficient?

A: X7R designation indicates the capacitor maintains stable capacitance across the operating temperature range of -55°C to 125°C, with maximum capacitance change of ±15% over this range. Both parts meet this specification.

Q: Does the packaging format differ between these parts?

A: The CDE part is supplied in standard packaging, while the KEMET substitute is supplied in Tape & Reel (TR) format. Both are 0603 (1608 Metric) surface mount packages compatible with automated assembly equipment.

Q: Are both parts RoHS compliant?

A: Yes. Both the CDE C0603C331K2RAC and KEMET C0603C331K2RAC7867 are ROHS3 compliant, meeting environmental and regulatory requirements.

Q: What is Moisture Sensitivity Level 1?

A: MSL 1 indicates unlimited shelf life without moisture baking requirements. Both parts can be stored and handled under standard conditions without special moisture control procedures.
