Substitute Part Grouping Explanation

Substitute parts for the KEMET C0603X331M4HAC7867 are identified based on the following substitution criteria:

Critical Parameters (Must Match Exactly):

• Capacitance: 330 pF
• Temperature Coefficient: X8R
• Operating Temperature Range: -55°C to 150°C
• Package / Case: 0603 (1608 Metric)
• Mounting Type: Surface Mount, MLCC
• Physical Dimensions: 0.063" L x 0.031" W (1.60mm x 0.80mm), Thickness ≤ 0.037" (0.95mm)

Allowable Variations (Can Be Upgraded):

• Voltage Rating: Can be equal to or higher than 16V
• Tolerance: Can be equal to or tighter than ±20%

The substitute part C0603X331G5HAC7867 meets all critical parameters while providing an upgraded voltage rating (50V vs. 16V) and improved tolerance (±2% vs. ±20%), making it a direct electrical and mechanical substitute.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: C0603X331M4HAC7867

• Use when circuit design specifies 16V rated voltage and ±20% tolerance is acceptable
• Suitable for cost-optimized applications with lower voltage requirements
• Active product status ensures continued availability

Substitute Part: C0603X331G5HAC7867

• Use as direct replacement when higher voltage margin is required (50V rating)
• Provides improved tolerance specification (±2%) for applications requiring tighter capacitance control
• Identical physical footprint and thermal characteristics ensure drop-in compatibility
• Active product status with higher inventory availability (22,829 pcs vs. 872 pcs)
• Both parts maintain identical compliance certifications (ROHS3, REACH Unaffected, MSL 1)

Selection Basis: Substitution is valid based on matching capacitance (330 pF), temperature coefficient (X8R), operating temperature range (-55°C to 150°C), package form factor (0603), and physical dimensions. The substitute part represents an electrical upgrade with no mechanical incompatibility.

Frequently Asked Questions (FAQ)

Q: Can C0603X331G5HAC7867 replace C0603X331M4HAC7867 in any application?

A: Yes, within the constraints of circuit design. The substitute part has identical capacitance, temperature coefficient, operating temperature range, and physical dimensions. The higher voltage rating (50V vs. 16V) and tighter tolerance (±2% vs. ±20%) are engineering upgrades that do not create incompatibility. Verify that the circuit board layout and component placement accommodate the identical 0603 package dimensions.

Q: What is the difference between ±20% and ±2% tolerance?

A: Tolerance specifies the allowable deviation from the nominal 330 pF capacitance value. C0603X331M4HAC7867 allows deviation between 264 pF and 396 pF. C0603X331G5HAC7867 allows deviation between 323.4 pF and 336.6 pF. The tighter tolerance of the substitute part provides more precise capacitance control, beneficial for applications requiring stable frequency response or impedance matching.

Q: Does the 50V rating of the substitute part affect circuit performance?

A: No. Voltage rating indicates the maximum voltage the capacitor can withstand without breakdown. A higher voltage rating does not change the capacitor's electrical behavior at lower voltages. If the circuit operates at 16V or below, both parts perform identically.

Q: Are the physical dimensions identical?

A: Yes. Both parts are 0603 (1608 Metric) package with dimensions 0.063" L x 0.031" W (1.60mm x 0.80mm) and maximum thickness 0.037" (0.95mm). They are mechanically interchangeable on PCB layouts designed for 0603 components.

Q: What is the significance of X8R temperature coefficient?

A: X8R specifies the capacitance change across the operating temperature range. X8R means capacitance variation is within ±15% from -55°C to 150°C. Both parts have identical X8R specification, ensuring equivalent thermal stability.

Q: Are both parts RoHS compliant?

A: Yes. Both C0603X331M4HAC7867 and C0603X331G5HAC7867 are ROHS3 Compliant and REACH Unaffected, meeting environmental and regulatory requirements for electronic component manufacturing and use.

Q: What does MSL 1 rating mean?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture baking requirements. Both parts have MSL 1 rating, meaning they can be stored and handled without special moisture control procedures.

Q: Which part should be selected for new designs?

A: For new designs, C0603X331G5HAC7867 is recommended when voltage margin and tolerance precision are design considerations. Both parts are Active status with continued manufacturer support. Verify component availability and cost factors for your specific procurement timeline.
