Engineering Selection Recommendations

The C0603C182K1RAC7867 from KEMET is the direct functional equivalent for the obsolete C0603C182K1RAC. Selection of this substitute is based on the following engineering criteria:

Product Status: The KEMET part maintains active product status, ensuring long-term availability and supply chain continuity compared to the obsolete Cornell Dubilier component.

Electrical Equivalence: Both parts share identical capacitance (1800 pF), tolerance (±10%), voltage rating (100V), and temperature coefficient (X7R), ensuring functional interchangeability in circuit applications.

Mechanical Compatibility: The KEMET substitute maintains identical package dimensions (0603/1608 Metric) and mounting technology (Surface Mount, MLCC), with thickness within acceptable tolerance (0.034" versus 0.035" maximum).

Compliance Alignment: Both components are ROHS3 compliant with MSL 1 rating, meeting environmental and reliability standards for the application.

Packaging Consideration: The KEMET part is supplied in Tape & Reel format, which is standard for production environments and offers advantages for automated assembly processes compared to bulk packaging.

Frequently Asked Questions (FAQ)

Q: Can the C0603C182K1RAC7867 be used as a direct replacement for the C0603C182K1RAC?

A: Yes. Both parts are electrically and mechanically equivalent with identical capacitance (1800 pF), voltage rating (100V), temperature coefficient (X7R), and package dimensions (0603/1608 Metric). The KEMET substitute is suitable for direct substitution in all applications where the Cornell Dubilier part was specified.

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

A: X7R designates a temperature coefficient of ±15% over the operating range of -55°C to 125°C. This classification ensures stable capacitance performance across the full temperature range, making it suitable for general-purpose and bypass/decoupling applications where temperature stability is required.

Q: Are there differences in physical dimensions between these parts?

A: Both parts conform to the 0603 (1608 Metric) package standard with identical length (0.063" / 1.60mm) and width (0.031" / 0.80mm). The KEMET part has a maximum thickness of 0.034" (0.87mm) compared to 0.035" (0.90mm) for the Cornell Dubilier part. This minor difference is within acceptable tolerance for PCB assembly and does not affect interchangeability.

Q: What is the Moisture Sensitivity Level (MSL) and why does it matter?

A: Both parts carry MSL 1 rating, indicating unlimited shelf life without moisture absorption concerns. This classification eliminates the need for special storage conditions or baking procedures prior to assembly, simplifying inventory management and reducing handling requirements.

Q: Does the packaging format affect electrical performance?

A: No. The Tape & Reel (TR) packaging of the KEMET substitute provides the same electrical performance as the bulk-packaged Cornell Dubilier part. Tape & Reel format is standard for production environments and offers advantages for automated pick-and-place assembly.

Q: Are both parts RoHS compliant?

A: Yes. Both the C0603C182K1RAC and C0603C182K1RAC7867 are ROHS3 compliant, meeting environmental regulations for restricted substances in electrical and electronic equipment.
