1210J2K00331MXT Equivalent & Substitute Parts

Part Overview

The 1210J2K00331MXT is a 330 pF ceramic capacitor rated for 2000V (2kV) with X7R temperature coefficient, manufactured by Knowles Syfer in 1210 (3225 Metric) surface mount package. This component is designed for general purpose high-voltage applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is currently active and in stock, with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent parts are identified when they maintain the same capacitance value, voltage rating, package dimensions, and mounting characteristics while potentially offering different temperature coefficient specifications or tolerance grades.

Substitute Part Grouping Explanation

Substitution eligibility for the 1210J2K00331MXT is determined by strict equivalence in the following parameters: capacitance value (330 pF), voltage rating (2000V), package type (1210/3225 Metric), and mounting method (surface mount MLCC). The substitute part C1210C331JGGAC7800 meets all these core requirements. Differences in temperature coefficient (X7R versus C0G/NP0) and tolerance (±20% versus ±5%) represent variations within the allowed substitution criteria for this product category. Both parts maintain identical operating temperature ranges, RoHS3 compliance, and MSL 1 ratings. Physical dimensions remain compatible within the 1210 package specification, with thickness variations (2.00mm maximum versus 2.30mm maximum) remaining within acceptable PCB assembly tolerances for this package class.

Parameter Comparison

Engineering Selection Recommendations

Both the 1210J2K00331MXT and C1210C331JGGAC7800 are active products with ROHS3 compliance and REACH unaffected status, making either suitable for current design implementations. The primary distinction lies in temperature coefficient specification: X7R provides ±15% capacitance change across the operating temperature range, while C0G/NP0 provides ±0.3% change, offering superior stability in temperature-sensitive applications. The KEMET substitute offers tighter tolerance (±5% versus ±20%), which may provide improved circuit performance where capacitance precision is critical. The thickness difference (2.30mm versus 2.00mm maximum) requires verification against PCB assembly clearance specifications for the target application. Both parts carry identical voltage ratings, package dimensions, and moisture sensitivity classifications, ensuring mechanical and electrical compatibility within the 1210 form factor.

Frequently Asked Questions (FAQ)

Q: Can C1210C331JGGAC7800 directly replace 1210J2K00331MXT in existing designs?

A: Direct replacement is possible when the application tolerates the thickness variation (2.30mm versus 2.00mm maximum) and benefits from or is unaffected by the superior temperature stability of C0G/NP0 coefficient. PCB assembly clearance must be verified for the increased thickness.

Q: What is the significance of the temperature coefficient difference between X7R and C0G/NP0?

A: X7R exhibits ±15% capacitance variation across -55°C to 125°C operating range. C0G/NP0 exhibits ±0.3% variation across the same range. Selection depends on circuit requirements for capacitance stability at temperature extremes.

Q: Does the ±5% tolerance of the substitute part provide advantages over the ±20% tolerance of the original?

A: Tighter tolerance (±5%) reduces capacitance variation between individual components, improving circuit consistency and performance predictability in applications where capacitance precision affects circuit behavior.

Q: Are both parts suitable for high-voltage applications?

A: Both parts are rated for 2000V (2kV) and carry identical voltage specifications, making them equally suitable for high-voltage circuit applications within this rating.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity) ratings, ensuring compatibility with current manufacturing and environmental standards.
