CL10B682KB8NNWC Equivalent & Substitute Parts

Part Overview

The CL10B682KB8NNWC 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) is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is currently active in production and ROHS3 compliant with MSL 1 rating.

Substitute parts are necessary when the original part becomes unavailable, when packaging requirements change, or when enhanced specifications (such as improved tolerance or automotive-grade ratings) are required for specific applications.

Substitute Part Grouping Explanation

Substitute parts for the CL10B682KB8NNWC are classified into three categories based on their relationship to the original specification:

Upgrade Substitutes maintain all critical electrical parameters (6800 pF, 50V, X7R, -55°C to 125°C) while offering enhanced specifications such as improved tolerance (±5% instead of ±10%) or automotive-grade certifications (AEC-Q200). These parts are direct functional upgrades suitable for applications requiring higher precision or automotive reliability standards.

Parametric Equivalents match all electrical and mechanical specifications exactly, differing only in packaging format (Cut Tape instead of Tape & Reel) or inventory availability. These parts are interchangeable at the component level with no performance difference.

Direct Equivalents from alternative manufacturers (KEMET, TDK, KYOCERA AVX, Vishay Vitramon, YAGEO) provide identical electrical performance and package specifications. Selection among these parts depends on supply chain availability, preferred supplier relationships, and application-specific certifications.

The critical parameters determining substitution eligibility are: capacitance value (6800 pF), voltage rating (minimum 50V), temperature coefficient (X7R), package size (0603), and operating temperature range (-55°C to 125°C).

Engineering Selection Recommendations

For General-Purpose Applications with Standard Tolerance Requirements: Select CL10B682KB8NNNC (Samsung Electro-Mechanics) or equivalent parts from KEMET (C0603C682K5RAC7867), KYOCERA AVX (KGM15AR71H682KT), or Vishay Vitramon (VJ0603Y682KXACW1BC). All maintain identical electrical specifications and ROHS3 compliance. Selection should prioritize supplier availability and established procurement relationships.

For Applications Requiring Improved Tolerance: CL10B682JB8NNNC (Samsung Electro-Mechanics) provides ±5% tolerance while maintaining all other specifications. This upgrade is suitable for circuits with tighter capacitance requirements.

For Automotive Applications: CL10B682KB8WPNC (Samsung Electro-Mechanics), AC0603KPX7R9BB682 (YAGEO), or AC0603KRX7R9BB682 (YAGEO) are qualified to AEC-Q200 automotive standards. These parts are required for automotive-grade designs and supply chain traceability.

For Higher Voltage Margin Applications: CGJ3E2X7R2A682K080AA (TDK Corporation) provides 100V rating instead of 50V. Note that this part is currently obsolete; use only if existing inventory is available and no active alternatives meet application requirements.

Packaging Considerations: Tape & Reel packaging is standard for high-volume production. Cut Tape format is suitable for lower-volume or prototype applications. Digi-Reel format (CL10B682JB8NNNC) offers flexibility between these options.

Frequently Asked Questions (FAQ)

Q: Can I substitute CL10B682KB8NNWC with a part rated at 100V instead of 50V? A: Yes. A higher voltage rating (100V) is electrically compatible with a 50V application. The CGJ3E2X7R2A682K080AA (100V rated) is a valid substitute. However, verify that the higher voltage rating does not introduce undesired characteristics for your specific circuit design.

Q: What is the difference between ±10% and ±5% tolerance parts? A: Tolerance specifies the allowable deviation from the nominal 6800 pF value. ±10% allows deviation from 6120 pF to 7480 pF. ±5% allows deviation from 6460 pF to 7140 pF. Tighter tolerance (±5%) is suitable for precision circuits; standard tolerance (±10%) is acceptable for general-purpose applications.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts are ROHS3 compliant and MSL 1 rated, meeting current regulatory requirements and handling standards.

Q: Can I use Tape & Reel parts in place of Cut Tape parts? A: Yes. Both packaging formats contain identical components. The difference is in the delivery format for assembly. Tape & Reel is standard for automated pick-and-place equipment; Cut Tape is used for manual or lower-volume assembly. Verify your assembly equipment compatibility before switching formats.

Q: What does AEC-Q200 certification mean? A: AEC-Q200 is an automotive industry standard qualification. Parts with this certification have undergone additional reliability testing and are approved for automotive applications. Use AEC-Q200 certified parts (CL10B682KB8WPNC, AC0603KPX7R9BB682, AC0603KRX7R9BB682) for automotive designs.

Q: Is CL10B682KB8NNNC a direct replacement for CL10B682KB8NNWC? A: Yes. CL10B682KB8NNNC is a parametric equivalent with identical electrical specifications. The only difference is packaging format (Cut Tape vs. Tape & Reel). Both are Samsung Electro-Mechanics parts with active product status.

Q: Why is CGJ3E2X7R2A682K080AA listed as obsolete? A: Product status indicates that TDK Corporation has discontinued this part. While existing inventory may be available, it should not be selected for new designs. Use active alternatives from other manufacturers instead.

Q: Can I mix different manufacturers' parts in the same circuit board? A: Yes. All listed substitute parts meet identical electrical and mechanical specifications. Mixing manufacturers is acceptable from a technical standpoint. However, verify that your procurement and quality assurance processes support multiple suppliers for this component.
