Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C0402C331M4JAC7867 is determined by the following critical parameters that must remain constant across all equivalent parts:

Fixed Parameters (Non-Negotiable):

• Capacitance: 330 pF
• Package / Case: 0402 (1005 Metric)
• Temperature Coefficient: U2J
• Operating Temperature Range: -55°C ~ 125°C
• Mounting Type: Surface Mount, MLCC
• Physical Dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm)
• Thickness (Max): 0.022" (0.55mm)

Variable Parameters (Substitution Allowed):

• Voltage - Rated: May be increased from 16V to higher ratings
• Tolerance: May be improved from ±20% to tighter specifications

The identified substitute part C0402C331J5JAC7867 maintains all fixed parameters while offering enhanced voltage rating (50V) and improved tolerance (±5%), making it suitable for applications where the original 16V specification provides insufficient voltage margin or where tighter capacitance tolerance is required.

Engineering Selection Recommendations

C0402C331M4JAC7867 Selection Criteria:

• Applications with circuit voltage specifications limited to 16V maximum
• Cost-sensitive designs where standard ±20% tolerance meets functional requirements
• General-purpose applications with established design margins

C0402C331J5JAC7867 Selection Criteria:

• Applications requiring voltage derating margin beyond 16V specification
• Designs demanding improved capacitance tolerance (±5% vs ±20%)
• Systems where component reliability and tighter value distribution are prioritized
• Circuits operating near maximum voltage limits where higher-rated components provide safety margin

Both parts maintain identical RoHS3 compliance, REACH unaffected status, and MSL 1 rating, ensuring equivalent environmental and regulatory compliance. Both are manufactured by KEMET and remain in active production status with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can C0402C331J5JAC7867 directly replace C0402C331M4JAC7867 in existing designs?

A: Direct replacement is possible from a physical and electrical standpoint. The substitute part maintains identical capacitance (330 pF), package dimensions (0402), temperature coefficient (U2J), and operating temperature range (-55°C ~ 125°C). The higher voltage rating (50V vs 16V) and improved tolerance (±5% vs ±20%) are compatible with any circuit designed for the original part. However, design verification should confirm that the higher voltage rating does not introduce unintended circuit behavior changes.

Q: What is the significance of the tolerance difference between ±20% and ±5%?

A: Tolerance defines the acceptable capacitance value range around the nominal 330 pF specification. The C0402C331M4JAC7867 allows values between 264 pF and 396 pF. The C0402C331J5JAC7867 restricts values to 313.5 pF and 346.5 pF. Tighter tolerance (±5%) provides more predictable circuit behavior in applications sensitive to capacitance variation, such as timing circuits or precision filtering networks.

Q: Are there any package or mounting differences between these parts?

A: No. Both parts use identical 0402 (1005 Metric) surface mount packages with matching physical dimensions (0.039" L x 0.020" W, 1.00mm x 0.50mm) and maximum thickness (0.022" / 0.55mm). PCB footprints, reflow profiles, and assembly processes are interchangeable.

Q: Why would a design use the 16V-rated part instead of the 50V-rated substitute?

A: The 16V-rated C0402C331M4JAC7867 is selected when circuit voltage specifications are confirmed at or below 16V and cost optimization is a design priority. Higher voltage-rated capacitors typically command higher unit costs. When voltage margins are adequate and tolerance requirements are non-critical, the lower-rated part provides cost efficiency without compromising functionality.

Q: Are both parts compliant with current environmental and regulatory standards?

A: Yes. Both C0402C331M4JAC7867 and C0402C331J5JAC7867 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. Both maintain identical compliance status and are suitable for applications requiring environmental regulation adherence.
