08051C561KAT2A Ceramic Capacitor 560pF 100V X7R 0805 Equivalent & Substitute Parts

Part Overview

The 08051C561KAT2A is a surface mount multilayer ceramic capacitor (MLCC) manufactured by KYOCERA AVX with a capacitance of 560 pF, rated voltage of 100V, and X7R temperature coefficient. This component is classified as active and in full production. Equivalent and substitute parts are identified based on matching or exceeding electrical specifications while maintaining the same 0805 (2012 Metric) package footprint and surface mount mounting type. Substitutes are necessary when the primary part is unavailable, when higher voltage ratings or improved tolerance specifications are required, or when alternative temperature coefficient characteristics better suit application requirements.

Substitute Part Grouping Explanation

Substitution logic for the 08051C561KAT2A is based on the following criteria:

Voltage Rating: Substitute parts must maintain a minimum voltage rating of 100V. Parts with higher voltage ratings (200V, 500V) are acceptable as direct upgrades and provide additional design margin.

Capacitance: All substitute parts must maintain exactly 560 pF capacitance to ensure circuit functionality.

Temperature Coefficient: Substitutes are grouped into two categories: X7R temperature coefficient (matching the original) and C0G/NP0 temperature coefficient (superior stability, acceptable for general purpose applications).

Tolerance: The original part specifies ±10% tolerance. Substitutes with tighter tolerances (±5%, ±2%, ±1%) are acceptable upgrades. Substitutes with looser tolerances are not acceptable.

Package and Mounting: All substitutes must use the 0805 (2012 Metric) surface mount package to ensure PCB footprint compatibility.

Compliance: All substitute parts must maintain ROHS3 compliance and MSL 1 rating to meet environmental and handling requirements.

Engineering Selection Recommendations

Direct Equivalent (Same Specifications): C0805C561K1RAC7800 (KEMET) is a direct equivalent with identical electrical specifications: 560 pF, ±10% tolerance, 100V rating, and X7R temperature coefficient. This part is ROHS3 compliant and maintains full compatibility with the original design.

Voltage Upgrade (Same Tolerance, Higher Voltage): 08052C561KAT2A (KYOCERA AVX) provides a voltage upgrade to 200V while maintaining ±10% tolerance and X7R characteristics. This substitution increases design margin without altering circuit behavior and is ROHS3 compliant.

Voltage and Tolerance Upgrade (Higher Voltage, Tighter Tolerance): 08052C561JAT2A (KYOCERA AVX) combines 200V voltage rating with improved ±5% tolerance, both upgrades from the original specification. This part is ROHS3 compliant and suitable for applications requiring enhanced performance.

Temperature Coefficient Upgrade (C0G/NP0 Stability): KGM21BCG2A561JT (KYOCERA AVX) and C0805C561J1GAC7800 (KEMET) both provide C0G/NP0 temperature coefficient with ±5% tolerance at 100V rating. C0G/NP0 offers superior temperature stability compared to X7R and is appropriate for precision applications. Both are ROHS3 compliant.

High Voltage Upgrade (500V Rating): C0805C561JCGAC7800 (KEMET) provides a 500V rating with C0G/NP0 temperature coefficient and ±5% tolerance. This part is suitable for high-voltage circuit applications and is ROHS3 compliant.

Non-Compliant Part (Not Recommended): C0805C561J1GAL7800 (KEMET) is RoHS non-compliant and should not be selected for new designs or applications requiring RoHS3 certification.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a higher voltage rating than the original 08051C561KAT2A?

A: Yes. A higher voltage rating provides additional design margin and does not negatively impact circuit performance. Parts rated at 200V or 500V are acceptable substitutes for a 100V application.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients?

A: X7R temperature coefficient provides ±15% capacitance variation across the -55°C to 125°C operating range. C0G/NP0 provides superior stability with minimal capacitance variation across temperature. C0G/NP0 is preferred for precision timing circuits, filters, and applications sensitive to capacitance drift.

Q: Can I substitute a part with ±5% tolerance for the original ±10% tolerance part?

A: Yes. Tighter tolerance specifications are acceptable upgrades and provide improved component consistency. A ±5% part will perform within the circuit requirements established for a ±10% part.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All listed substitute parts use the 0805 (2012 Metric) surface mount package, ensuring identical PCB footprint compatibility. Physical dimensions and lead spacing are equivalent across all substitutes.

Q: Why should I avoid the C0805C561J1GAL7800 part?

A: This part is RoHS non-compliant, which violates environmental regulations in many jurisdictions and may not meet procurement requirements for new designs. ROHS3-compliant alternatives are available and should be selected instead.

Q: Which substitute offers the best availability?

A: KGM21BCG2A561JT (KYOCERA AVX) has the highest inventory at 38,573 pieces, followed by C0805C561F1GAC7800 (KEMET) at 16,503 pieces. Both are ROHS3 compliant and suitable for high-volume applications.

Q: Can I use KEMET parts as substitutes for KYOCERA AVX parts?

A: Yes. KEMET C0805 series parts with matching electrical specifications are direct substitutes. Both manufacturers produce ROHS3-compliant 0805 ceramic capacitors with equivalent performance characteristics.
