CL10B561KB8NNWC Equivalent & Substitute Parts

Part Overview

The CL10B561KB8NNWC is a 560 pF ±10% 50V ceramic capacitor manufactured by Samsung Electro-Mechanics in the 0603 (1608 Metric) surface mount package. This multilayer ceramic capacitor (MLCC) with X7R temperature coefficient is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is ROHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity protection.

Equivalent and substitute parts are necessary when the original part becomes unavailable, when design requirements demand higher voltage ratings or tighter tolerances, or when alternative manufacturers' inventory provides better availability and lead times.

Substitute Part Grouping Explanation

Substitution logic for the CL10B561KB8NNWC is based on strict electrical and mechanical parameter matching:

Direct Equivalents (Same Specifications): Parts with identical capacitance (560 pF), tolerance (±10%), voltage rating (50V), temperature coefficient (X7R), and package (0603) from different manufacturers are direct substitutes. These include KYOCERA AVX 06035C561KAT2A, KEMET C0603C561K5RAC7867, and Vishay Vitramon VJ0603Y561KXACW1BC.

Tolerance Upgrades: Parts with ±5% tolerance instead of ±10% represent improved accuracy while maintaining all other parameters. These include Samsung CL10B561JB8NNNC, KYOCERA AVX 06035C561JAT2A, and KEMET C0603C561J5RAC7867. Tighter tolerance does not affect circuit compatibility.

Voltage Upgrades: Parts rated at 100V instead of 50V provide higher voltage margin while maintaining 560 pF capacitance and X7R temperature coefficient. These include KYOCERA AVX 06031C561JAT2A, 06031C561KAT2A, KEMET C0603C561K1RAC7867, and Murata GRM188R72A561KA01D. Higher voltage ratings are backward compatible with 50V applications.

Combined Upgrades: Parts combining both tighter tolerance (±5%) and higher voltage rating (100V) represent the highest specification level, such as KYOCERA AVX 06031C561JAT2A.

All substitutes maintain ROHS3 compliance, MSL 1 rating, and -55°C to 125°C operating temperature range.

Engineering Selection Recommendations

For Direct Replacement (Same Specifications): Select KYOCERA AVX 06035C561KAT2A, KEMET C0603C561K5RAC7867, or Vishay Vitramon VJ0603Y561KXACW1BC when exact specification matching is required. All three are Active status products with ROHS3 compliance and MSL 1 rating. KYOCERA AVX offers the highest inventory availability (42762 Pcs), providing superior lead time assurance.

For Tolerance Upgrade (±5% Tolerance): Select Samsung CL10B561JB8NNNC, KYOCERA AVX 06035C561JAT2A, or KEMET C0603C561J5RAC7867 when circuit design benefits from tighter capacitance tolerance while maintaining 50V rating. All maintain Active product status and full compliance certifications.

For Voltage Upgrade (100V Rating): Select KYOCERA AVX 06031C561KAT2A or KEMET C0603C561K1RAC7867 when higher voltage margin is required. KYOCERA AVX 06031C561KAT2A provides the highest inventory (49854 Pcs) among 100V options. These parts are backward compatible with 50V applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute a 560 pF ±5% capacitor for the original ±10% part? A: Yes. Tighter tolerance (±5%) is a direct upgrade that does not affect circuit compatibility. The capacitor will perform identically to the original while providing improved accuracy.

Q: Is a 100V rated capacitor compatible with a 50V circuit application? A: Yes. Higher voltage rating is backward compatible. A 100V capacitor operates safely in a 50V circuit and provides additional voltage margin. Physical dimensions and electrical performance remain equivalent.

Q: What is the difference between the Samsung CL10B561KB8NNWC and CL10B561JB8NNNC? A: The primary difference is tolerance: KB8NNWC is ±10%, while JB8NNNC is ±5%. Both are 560 pF, 50V, X7R, 0603 package. The JB8NNNC represents a tolerance upgrade with higher inventory availability (1751 Pcs vs. 799 Pcs).

Q: Why does Murata GRM188R72A561KA01D show "Not For New Designs" status? A: This designation indicates the manufacturer has discontinued active promotion of this part for new product development. While inventory exists, KYOCERA AVX and KEMET alternatives are preferred for new designs.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitutes maintain ROHS3 compliance and MSL 1 rating, matching the original CL10B561KB8NNWC environmental and regulatory specifications.

Q: Can I mix different manufacturers' parts in the same production batch? A: Yes. All listed substitutes are electrically and mechanically equivalent within their specified parameter groups. Different manufacturers can be used interchangeably provided the capacitance, tolerance, voltage, and package specifications match circuit requirements.

Q: What is the significance of the 0603 package designation? A: 0603 (1608 Metric) is the physical footprint size: 0.063" L × 0.031" W (1.60mm × 0.80mm). All substitutes use this identical package, ensuring PCB layout and assembly compatibility without design modification.
