CL10C221KB8NNNC Equivalent & Substitute Parts

Part Overview

The CL10C221KB8NNNC is a 220 pF ceramic capacitor manufactured by Samsung Electro-Mechanics, rated at 50V with C0G/NP0 temperature coefficient in 0603 (1608 Metric) surface mount package. This component is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). The part is suitable for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. Equivalent and substitute parts are identified based on matching or superior electrical and mechanical specifications within the same package footprint and application class.

Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on substitution relationship and parameter alignment:

Upgrade Substitutes – Parts with improved or tighter specifications that maintain full backward compatibility:

Tolerance improvement from ±10% to ±5% or ±1% or ±2%
Same voltage rating (50V) or higher voltage rating
Identical package, temperature coefficient, and operating temperature range
Active product status with current manufacturing availability

Direct Substitutes – Parts with equivalent or superior specifications from alternative manufacturers:

Matching capacitance (220 pF) and voltage rating (50V or higher)
Identical or superior tolerance specifications
Same C0G/NP0 temperature coefficient
Identical 0603 package footprint
ROHS3 compliance and MSL 1 rating
Active or Obsolete product status noted where applicable

Substitution logic is based strictly on the following allowed parameters: capacitance value, tolerance, voltage rating, temperature coefficient, package size, mounting type, operating temperature range, and regulatory compliance status. All substitute parts maintain the same 0603 (1608 Metric) surface mount package and C0G/NP0 temperature stability required for general-purpose applications.

Engineering Selection Recommendations

Primary Upgrade Path – Samsung Electro-Mechanics Series: CL10C221JB8NNNC and CL10C221JB8NFNC are direct upgrades from CL10C221KB8NNNC within the same manufacturer's product line. Both parts improve tolerance specification from ±10% to ±5% while maintaining identical voltage rating (50V), temperature coefficient (C0G/NP0), package (0603), and operating temperature range (-55°C to 125°C). Both are Active status with ROHS3 compliance. CL10C221JB8NNNC offers higher inventory availability (240100 Pcs) compared to CL10C221JB8NFNC (480300 Pcs in Cut Tape packaging).

Equivalent Substitutes – KEMET Series: C0603C221K5GAC7867 provides equivalent specifications with ±10% tolerance and 50V rating from KEMET. This part is Active status with identical package and temperature coefficient. C0603C221J5GAC7867 offers ±5% tolerance upgrade at 50V rating with significantly higher inventory (256901 Pcs). Both KEMET parts feature Low ESL characteristic and are suitable for direct substitution.

Higher Voltage Alternatives: C0603C221J1GAC7867 (KEMET, 100V, ±5%) and CGJ3E2C0G2A221J080AA (TDK, 100V, ±5%) provide voltage margin above the 50V requirement. C0603C221J1GAC7867 is Active status with 118337 Pcs inventory. CGJ3E2C0G2A221J080AA is Obsolete status and should be avoided for new designs unless legacy compatibility is required.

Equivalent Alternative – KYOCERA AVX: KGM15ACG1H221KT matches the original specification with ±10% tolerance and 50V rating. This part is Active status with 40690 Pcs inventory and identical 0603 package footprint.

All recommended substitutes maintain ROHS3 compliance, MSL 1 rating, and operating temperature range of -55°C to 125°C. Selection should prioritize Active product status parts with adequate inventory for production requirements.

Frequently Asked Questions (FAQ)

Q: Can CL10C221JB8NNNC replace CL10C221KB8NNNC in existing designs? A: Yes. CL10C221JB8NNNC is a direct upgrade with improved ±5% tolerance versus the original ±10% tolerance. All other specifications including voltage (50V), temperature coefficient (C0G/NP0), package (0603), and operating temperature range (-55°C to 125°C) are identical. Both parts are Active status with ROHS3 compliance.

Q: What is the difference between KEMET C0603C221K5GAC7867 and C0603C221J5GAC7867? A: Both parts are from KEMET's SMD Comm C0G series in 0603 package with 50V rating. The primary difference is tolerance: C0603C221K5GAC7867 has ±10% tolerance (equivalent to the original part), while C0603C221J5GAC7867 has ±5% tolerance (upgrade specification). C0603C221J5GAC7867 offers higher inventory availability (256901 Pcs).

Q: Are TDK CGJ series parts suitable for new designs? A: CGJ3E2C0G2A221J080AA (100V) and CGJ3E3C0G2D221J080AA (200V) are both classified as Obsolete product status. These parts should not be selected for new designs. Use Active status alternatives such as KEMET or Samsung Electro-Mechanics parts instead.

Q: What packaging options are available for substitute parts? A: Substitute parts are available in multiple packaging formats: Cut Tape (CT), Tape & Reel (TR), and Digi-Reel® combinations. All packaging options maintain identical electrical specifications and 0603 footprint. Packaging selection depends on production volume and assembly process requirements.

Q: Can I use a 100V rated capacitor in place of the 50V original part? A: Yes. C0603C221J1GAC7867 (KEMET, 100V, ±5%) provides higher voltage margin while maintaining identical capacitance (220 pF), temperature coefficient (C0G/NP0), and package (0603). Higher voltage rating does not degrade performance in 50V applications and may improve reliability margin.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original CL10C221KB8NNNC specifications.

Q: What is the significance of Low ESL feature in KEMET parts? A: Low ESL (Equivalent Series Inductance) is a manufacturing characteristic that reduces parasitic inductance in the capacitor. This feature improves high-frequency performance but does not affect the core substitution criteria for general-purpose applications. Parts with Low ESL are suitable direct replacements.
