Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0603J2000331JXT is determined by the following criteria:

Mandatory Matching Parameters:

• Capacitance value: 330 pF
• Tolerance: ±5%
• Package / Case: 0603 (1608 Metric)
• Mounting Type: Surface Mount, MLCC
• Operating Temperature Range: -55°C to 125°C
• RoHS3 Compliance

Allowable Variations:

• Voltage Rating: Equal to or greater than 200V
• Temperature Coefficient: X7R or C0G/NP0 (both provide stable performance across the operating temperature range)
• Physical dimensions: Within standard 0603 package specifications

The substitute part C0603C331JAGAC7867 from KEMET meets all mandatory parameters with a higher voltage rating (250V) and C0G/NP0 temperature coefficient, making it electrically and mechanically compatible for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Both parts are active products with RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The C0603C331JAGAC7867 substitute provides equivalent or superior performance characteristics: identical capacitance and tolerance, higher voltage rating (250V vs 200V), and C0G/NP0 temperature coefficient which offers tighter capacitance stability compared to X7R. Physical compatibility is maintained within 0603 package specifications, with a maximum thickness difference of 0.007" (0.07mm) that remains within standard PCB assembly tolerances. Selection between these parts should be based on application-specific requirements, supply chain availability, and cost considerations.

Frequently Asked Questions (FAQ)

Q: Can C0603C331JAGAC7867 be used as a direct replacement for 0603J2000331JXT?

A: Yes. Both parts share identical capacitance (330 pF), tolerance (±5%), package (0603), and operating temperature range (-55°C to 125°C). The substitute has a higher voltage rating (250V) and different temperature coefficient (C0G/NP0 vs X7R), both of which are compatible with the original part's application requirements.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients?

A: X7R provides ±15% capacitance change across the operating temperature range. C0G/NP0 provides ±30 ppm/°C, resulting in tighter capacitance stability. Both coefficients are suitable for general purpose applications and maintain performance across -55°C to 125°C.

Q: Are there physical compatibility concerns with the thickness difference?

A: The thickness difference of 0.007" (0.07mm) between the two parts is within standard PCB assembly tolerances and does not affect mechanical compatibility or board-level performance.

Q: Do both parts meet current compliance requirements?

A: Yes. Both parts are RoHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings, meeting current regulatory and manufacturing standards.

Q: Why would I choose the substitute over the original part?

A: Selection depends on supply availability, cost, and application requirements. The substitute offers higher voltage rating and tighter temperature coefficient stability, which may provide additional design margin in certain applications.
