Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 0201X331K250CT are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain constant:

Electrical Parameters:

• Capacitance value: 330 pF
• Tolerance: ±10%
• Voltage rating: 25V
• Temperature coefficient: X5R
• Operating temperature range: -55°C ~ 85°C

Mechanical Parameters:

• Package type: 0201 (0603 Metric)
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
• Maximum thickness: 0.013" (0.33mm)
• Mounting type: Surface Mount, MLCC

Compliance Parameters:

• RoHS3 compliance
• REACH unaffected status
• Moisture sensitivity level: 1 (Unlimited)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. The GRM033R61E331KA01D from Murata Electronics meets all specified parameters and is identified as a parametric equivalent substitute.

Frequently Asked Questions (FAQ)

Q: Can the GRM033R61E331KA01D be used as a direct replacement for the 0201X331K250CT?

A: Yes. The GRM033R61E331KA01D is a parametric equivalent with identical capacitance (330 pF), voltage rating (25V), temperature coefficient (X5R), operating temperature range (-55°C ~ 85°C), package dimensions (0201/0603 Metric), and compliance certifications (ROHS3, REACH unaffected). Direct substitution is supported without circuit modification.

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

A: No. Both parts share identical physical specifications: 0.024" L x 0.012" W (0.60mm x 0.30mm) with maximum thickness of 0.013" (0.33mm). They are compatible with identical PCB footprints and assembly processes.

Q: What is the significance of the X5R temperature coefficient?

A: X5R temperature coefficient indicates the capacitor maintains stable capacitance across the operating temperature range of -55°C to 85°C, with maximum capacitance change of ±15% over this range. Both the Walsin and Murata parts meet this specification.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both the 0201X331K250CT and GRM033R61E331KA01D are rated at MSL 1 (Unlimited), indicating they have unlimited shelf life and do not require special moisture control during storage or handling.

Q: Can these parts be used interchangeably in high-reliability applications?

A: Both parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for high-reliability applications. Selection between manufacturers should be based on established qualification procedures and supplier approval processes specific to your application requirements.

Q: What is the tolerance specification for these capacitors?

A: Both parts have ±10% tolerance on the 330 pF capacitance value. This means the actual capacitance will fall between 297 pF and 363 pF at nominal conditions.

Q: Are these parts suitable for general purpose applications?

A: Yes. Both the 0201X331K250CT and GRM033R61E331KA01D are rated for general purpose applications. The 330 pF capacitance value and 25V rating are suitable for decoupling, filtering, and coupling applications in standard electronic circuits.
