Substitute Part Grouping Explanation

Substitute parts for the C1206C331K2RACTU are classified based on strict electrical and mechanical parameter alignment:

Parametric Equivalent (Same Temperature Coefficient): The CC1206KRX7RABB331 from YAGEO maintains identical X7R temperature coefficient, capacitance value (330 pF), voltage rating (200V), and package configuration (1206). Tolerance specification (±10%) matches exactly. This part is a direct parametric equivalent suitable for applications requiring X7R stability characteristics.

Similar Substitute (Alternative Temperature Coefficient): The KGM31BCG2D331JT from KYOCERA AVX provides the same capacitance (330 pF), voltage rating (200V), and package (1206), but uses C0G/NP0 temperature coefficient instead of X7R. The tolerance is tighter (±5%), and the operating temperature range remains -55°C ~ 125°C. This substitute is applicable in circuits where superior temperature stability and lower capacitance drift are beneficial, though the different dielectric material requires circuit-level validation.

Substitution Criteria (All Parts):

• Capacitance: 330 pF (exact match required)
• Voltage Rating: 200V (minimum requirement met)
• Package: 1206 (3216 Metric) (physical compatibility)
• Mounting: Surface Mount, MLCC (assembly compatibility)
• RoHS3 Compliance: All substitutes maintain regulatory status
• MSL Rating: All substitutes rated MSL 1 (Unlimited)
• Operating Temperature: All substitutes cover -55°C ~ 125°C range

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (C1206C331K2RACTU - KEMET): Use as the baseline component when KEMET supply is available. Active production status, established inventory levels (869 pcs), and full compliance certifications support reliable procurement.

First Alternative (CC1206KRX7RABB331 - YAGEO): Select when KEMET supply is constrained. Identical X7R temperature coefficient ensures equivalent capacitance stability performance. Parametric match across all critical electrical specifications (330 pF, ±10%, 200V, X7R, -55°C ~ 125°C) permits direct substitution without circuit redesign. Active production status and higher inventory availability (4680 pcs) support supply chain flexibility. RoHS3 and MSL 1 compliance maintained.

Secondary Alternative (KGM31BCG2D331JT - KYOCERA AVX): Select when superior temperature stability is required or when KEMET and YAGEO sources are unavailable. C0G/NP0 temperature coefficient provides tighter capacitance tolerance (±5% vs ±10%) and superior frequency stability. Identical package, voltage rating, and operating temperature range ensure mechanical and thermal compatibility. Active production status and substantial inventory (40955 pcs) support availability. RoHS3 and MSL 1 compliance maintained. Note: Different dielectric material (C0G vs X7R) may affect circuit performance in applications sensitive to capacitance drift; circuit validation is required before production deployment.

Compliance & Regulatory: All three parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification. MSL 1 (Unlimited) rating across all parts ensures equivalent moisture handling and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can CC1206KRX7RABB331 directly replace C1206C331K2RACTU without circuit modification?

A: Yes. Both parts share identical capacitance (330 pF), tolerance (±10%), voltage rating (200V), temperature coefficient (X7R), operating temperature range (-55°C ~ 125°C), and package (1206). Electrical and mechanical specifications are equivalent. Direct substitution is supported.

Q: What is the key difference between the YAGEO and KYOCERA AVX substitutes?

A: The YAGEO CC1206KRX7RABB331 uses X7R temperature coefficient (matching the original KEMET part), while the KYOCERA AVX KGM31BCG2D331JT uses C0G/NP0 temperature coefficient. X7R provides moderate capacitance stability across temperature, while C0G/NP0 provides superior stability with tighter tolerance (±5%). Both maintain 330 pF capacitance and 200V rating in 1206 package.

Q: Is the tighter tolerance (±5%) of the KYOCERA AVX part always better?

A: Tighter tolerance provides better capacitance consistency but does not automatically improve circuit performance. Selection depends on circuit requirements. If the application tolerates ±10% capacitance variation, the KEMET or YAGEO parts are suitable. If tighter tolerance is required for precision filtering or timing circuits, the KYOCERA AVX part is preferred. Circuit validation determines the appropriate choice.

Q: Are all three parts suitable for bypass and decoupling applications?

A: The KEMET C1206C331K2RACTU is specified for bypass and decoupling applications. The YAGEO and KYOCERA AVX parts are specified for general purpose applications. However, all three parts meet the electrical requirements (330 pF, 200V, appropriate temperature coefficient) for bypass and decoupling use. Application suitability is determined by circuit design requirements, not by manufacturer application classification.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. Storage time before soldering is unlimited, and no special moisture control measures are required during handling or storage. All three parts share this rating, ensuring equivalent moisture management requirements.

Q: Can these parts be used interchangeably in high-frequency circuits?

A: Capacitance value (330 pF) and package (1206) are identical across all parts. However, X7R and C0G/NP0 dielectrics exhibit different frequency response characteristics. The KEMET and YAGEO parts (X7R) are suitable for general frequency applications. The KYOCERA AVX part (C0G/NP0) provides superior frequency stability. Circuit-specific frequency requirements determine the appropriate selection.

Q: What inventory considerations apply to these substitutes?

A: KEMET C1206C331K2RACTU: 869 pcs available. YAGEO CC1206KRX7RABB331: 4680 pcs available. KYOCERA AVX KGM31BCG2D331JT: 40955 pcs available. Higher inventory levels for KYOCERA AVX and YAGEO parts support supply chain flexibility and reduce lead time risk.
