CL10B682KB8SFNC Equivalent & Substitute Parts

Part Overview

The CL10B682KB8SFNC is a 6800 pF ±10% 50V ceramic capacitor manufactured by Samsung Electro-Mechanics in the 0603 (1608 Metric) package with X7R temperature coefficient. This multilayer ceramic capacitor (MLCC) features soft termination technology and is classified as Active product status with 1155 units in current inventory.

Substitute parts are necessary when the original manufacturer part becomes unavailable, when alternative sourcing improves supply chain resilience, or when design requirements permit upgraded electrical specifications while maintaining mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts are grouped into two categories based on electrical specifications:

Direct Equivalents (Same Electrical Specifications): Parts with 6800 pF capacitance, ±10% tolerance, 50V voltage rating, X7R temperature coefficient, and 0603 package. These parts are mechanically and electrically interchangeable with the CL10B682KB8SFNC.

Upgraded Specifications: Parts with improved electrical characteristics (higher voltage rating or tighter tolerance) while maintaining the same capacitance, temperature coefficient, and package. These parts are backward compatible but offer enhanced performance margins.

Critical Substitution Parameters:

Capacitance value: 6800 pF (non-negotiable)
Temperature coefficient: X7R (non-negotiable)
Package: 0603 (1608 Metric) (non-negotiable)
Voltage rating: minimum 50V (higher acceptable)
Tolerance: ±10% or tighter (tighter acceptable)
Mounting type: Surface Mount MLCC (non-negotiable)

Engineering Selection Recommendations

For Direct Replacement (Same Specifications):

Select from parts with Active product status and matching 50V voltage rating:

KEMET C0603C682K5RAC7867 or C0603X682K5RAC7867: Active status, high inventory (117,903 and 7,294 units respectively), ROHS3 compliant, MSL 1. The C0603X variant includes soft termination feature matching the original part.
YAGEO CC0603KRX7R9BB682: Active status, 67,613 units in stock, ROHS3 compliant, MSL 1.
KYOCERA AVX KGM15AR71H682KT: Active status, 78,292 units in stock, ROHS3 compliant, MSL 1.
Vishay Vitramon VJ0603Y682KXACW1BC: Active status, 8,686 units in stock, ROHS3 compliant, MSL 1.

For Upgraded Performance (Higher Voltage or Tighter Tolerance):

KEMET C0603C682J5RAC7867: Offers ±5% tolerance (tighter than ±10%) at 50V rating, Active status, 26,210 units in stock. Suitable when improved capacitance accuracy is required.

Frequently Asked Questions (FAQ)

Q: Can I use a 100V rated capacitor in place of the 50V CL10B682KB8SFNC?

A: Yes. A higher voltage rating is electrically acceptable and provides additional safety margin. The C1608X7R2A682K080AA (100V) and C0603C682J1RAC7867 (100V) are valid substitutes. However, verify that the application circuit design does not depend on the specific voltage rating for other functional reasons.

Q: What is the difference between KEMET C0603C682K5RAC7867 and C0603X682K5RAC7867?

A: Both parts have identical electrical specifications (6800 pF, ±10%, 50V, X7R, 0603). The C0603X variant includes soft termination feature, matching the original CL10B682KB8SFNC. Select C0603X682K5RAC7867 if soft termination is a design requirement; otherwise, both are functionally equivalent.

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

A: Yes. Tighter tolerance is an upgrade and is backward compatible. Parts like KEMET C0603C682J5RAC7867 (±5%, 50V) and C0603C682J1RAC7867 (±5%, 100V) provide improved capacitance accuracy without affecting circuit compatibility.

Q: Why are some substitute parts listed as "Not For New Designs" or "Obsolete"?

A: These designations indicate the manufacturer is discontinuing the product line. While functional equivalents exist, these parts should not be selected for new designs due to uncertain long-term availability. Use only for legacy system repairs or maintenance.

Q: Does packaging type (Tape & Reel vs. Bulk) affect electrical performance?

A: No. Packaging type affects only logistics, handling, and assembly processes. Tape & Reel packaging is standard for automated assembly; Bulk packaging is used for manual assembly or small quantities. Electrical performance is identical.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed in this reference maintain ROHS3 compliance and are suitable for applications requiring regulatory compliance with hazardous substance restrictions.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. This simplifies inventory management and reduces risk of moisture-induced failures during assembly.
