Substitute Part Grouping Explanation

Substitution of the C0402C331M3JAC7867 is determined by strict equivalence in the following parameters:

Fixed Parameters (Non-Negotiable):

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

Allowable Variation Parameters:

• Voltage - Rated: Equal or higher voltage rating
• Tolerance: Equal or tighter tolerance specification
• RoHS and MSL compliance: Must maintain or exceed current compliance level

The substitute part C0402C331J5JAC7867 maintains all fixed parameters while providing an upgraded voltage rating (50V vs. 25V) and improved tolerance specification (±5% vs. ±20%), making it suitable for applications requiring enhanced performance margins or stricter capacitance accuracy.

Parameter Comparison

Engineering Selection Recommendations

C0402C331M3JAC7867 is the primary selection for applications with circuit voltage requirements at or below 25V and where ±20% capacitance tolerance meets design specifications. This part maintains active product status with full ROHS3 compliance and unlimited moisture sensitivity rating.

C0402C331J5JAC7867 serves as a direct substitute when design requirements include:

• Circuit voltage operation at 25V to 50V range, providing additional safety margin
• Stricter capacitance tolerance specification (±5% vs. ±20%) for precision-critical applications
• Enhanced reliability through higher voltage derating

Both parts share identical physical dimensions, mounting characteristics, and temperature operating range, ensuring PCB layout and assembly process compatibility. Selection between these parts depends solely on circuit voltage requirements and capacitance tolerance specifications. Both maintain active product status and full regulatory compliance (ROHS3, REACH Unaffected, EAR99 classification).

Frequently Asked Questions (FAQ)

Q: Can C0402C331J5JAC7867 replace C0402C331M3JAC7867 in all applications?

A: C0402C331J5JAC7867 is a direct substitute when the circuit design operates at or below 50V. The higher voltage rating (50V vs. 25V) and tighter tolerance (±5% vs. ±20%) provide enhanced performance margins. Substitution is valid for any application originally designed for the main part.

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

A: Tolerance specifies the allowable deviation from the nominal 330 pF capacitance value. The main part (±20%) allows capacitance between 264 pF and 396 pF. The substitute part (±5%) restricts capacitance between 313.5 pF and 346.5 pF, providing tighter capacitance accuracy for precision applications.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 0402 (1005 Metric) package with identical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm) and maximum thickness of 0.022" (0.55mm). PCB footprints and assembly processes are fully compatible.

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

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: What is the temperature coefficient U2J?

A: U2J is the temperature coefficient classification for this ceramic capacitor series, indicating the capacitance change across the -55°C to 125°C operating temperature range. Both parts share identical temperature coefficient specifications.

Q: Are there any compliance differences between the two parts?

A: No. Both parts are ROHS3 compliant, REACH Unaffected, and classified as EAR99 for export control purposes. Regulatory compliance is equivalent.
