Key Parameters

Substitute Part Grouping Explanation

Substitution of the C1005JB1H331M050BA is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Capacitance value: 330 pF (exact match required)
• Voltage rating: 50V minimum (equal or higher acceptable)
• Package / Case: 0402 (1005 Metric) (exact match required)
• Mounting type: Surface Mount, MLCC (exact match required)
• Physical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm) (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Secondary Substitution Criteria:

• Tolerance: ±20% or tighter (tighter tolerance acceptable)
• Temperature coefficient: JB or equivalent stable coefficient (C0G/NP0 or X7R acceptable for general purpose applications)
• Operating temperature range: -25°C ~ 85°C minimum coverage (wider range acceptable)

Substitute parts must satisfy all primary criteria. Secondary criteria allow for improved specifications compared to the original part.

Parameter Comparison

Engineering Selection Recommendations

TDK C0G/NP0 Series (Recommended for Direct Substitution): The C1005C0G1H331F050BA, C1005C0G1H331G050BA, and C1005C0G1H331J050BA represent the most direct substitutes from TDK Corporation. These parts maintain identical package specifications and voltage rating while offering improved tolerance grades (±1%, ±2%, ±5% respectively) and extended operating temperature range (-55°C ~ 125°C). All three parts are ROHS3 Compliant and REACH Unaffected. The C1005C0G1H331J050BA provides the closest tolerance match to the original ±20% specification at ±5%.

KEMET Active Series (Preferred for New Designs): The KEMET C0402C331J5GAC7867 and C0402C331K5GAC7867 offer Active product status with superior availability (227,580 and 69,654 units respectively). Both maintain 50V rating, 0402 package, and C0G/NP0 temperature coefficient. The C0402C331J5GAC7867 (±5% tolerance) provides optimal balance between tolerance specification and component availability. Both parts are ROHS3 Compliant and REACH Unaffected.

Murata X7R Alternative: The GRM155R71H331KA01D from Murata Electronics provides an alternative with X7R temperature coefficient and ±10% tolerance. This part maintains 50V rating and 0402 package but carries Not For New Designs status. Selection of this part should be limited to applications where X7R temperature stability characteristics are specifically required.

Voltage Rating Consideration: The KEMET C0402C331JAGAC7867 operates at 250V rating with identical 330 pF capacitance and 0402 package. This part is not recommended as a direct substitute due to voltage rating exceeding application requirements and increased thickness (0.024" vs. 0.022").

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with tighter tolerance than the original ±20%? A: Yes. Tighter tolerance specifications (±1%, ±2%, ±5%, ±10%) are acceptable substitutes as they provide improved accuracy while maintaining electrical compatibility. The application circuit will function correctly with improved tolerance performance.

Q: What is the difference between C0G and JB temperature coefficients? A: Both are stable temperature coefficient designations suitable for general purpose applications. C0G (also designated NP0) provides superior temperature stability across -55°C ~ 125°C. JB provides stability across -25°C ~ 85°C. C0G/NP0 substitutes offer extended temperature range coverage without compromising circuit performance.

Q: Are KEMET and Murata parts compatible with TDK footprints? A: Yes. All substitute parts listed maintain identical 0402 (1005 Metric) package dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm). Physical footprint compatibility is guaranteed across all manufacturers listed.

Q: Why is the KEMET C0402C331J5GAC7867 recommended over other options? A: This part combines Active product status (ensuring long-term availability), highest inventory level (227,580 units), ±5% tolerance (closest to original ±20%), 50V rating match, and ROHS3 compliance. It represents the optimal balance of availability, specification match, and design status.

Q: Can I substitute with higher voltage rating parts? A: Yes. Parts rated at 50V or higher are electrically compatible. The C0402C331JAGAC7867 (250V rating) is mechanically compatible but not recommended due to increased thickness (0.024" vs. 0.022"), which may affect PCB assembly clearances.

Q: What does "Not For New Designs" product status mean? A: This designation indicates the manufacturer is not recommending the part for new circuit designs, though existing inventory remains available. For new designs, Active status parts (KEMET series) are preferred to ensure long-term supply continuity.
