CL21B102KCANNWC Equivalent & Substitute Parts
Part Overview
The CL21B102KCANNWC is a 1000 pF ±10% 100V X7R ceramic capacitor in 0805 (2012 Metric) surface mount package manufactured by Samsung Electro-Mechanics. 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 ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
Substitute parts are identified when design requirements change, inventory constraints occur, or when enhanced performance specifications are needed while maintaining functional compatibility within the same package footprint and electrical operating parameters.

Substitute Part Grouping Explanation
Substitute parts are classified into three categories based on their relationship to the main part CL21B102KCANNWC:
Upgrade Substitutes feature enhanced electrical specifications (tighter tolerance or higher voltage rating) while maintaining the same capacitance, package, and temperature coefficient. These parts provide improved performance margins and are direct functional upgrades.
Parametric Equivalents match all critical electrical and mechanical specifications of the main part but may differ in packaging format (Cut Tape vs. Tape & Reel) or internal construction details that do not affect circuit performance.
Direct Substitutes from alternative manufacturers provide identical electrical specifications and package dimensions, enabling cross-manufacturer sourcing while maintaining full functional compatibility.
Substitution eligibility is determined by the following criteria:
- Capacitance value must equal 1000 pF
- Temperature coefficient must be X7R
- Package must be 0805 (2012 Metric)
- Operating temperature range must include -55°C to 125°C
- Voltage rating must be ≥100V
- Tolerance may be equal or tighter (±10% or ±5%)
- RoHS3 compliance and MSL 1 rating required

Engineering Selection Recommendations
For Direct Replacement (Identical Specifications)
CL21B102KCANNNC (Samsung Electro-Mechanics) serves as a parametric equivalent with identical electrical specifications and thickness. This part is suitable when Samsung sourcing is preferred and packaging format (Cut Tape & Digi-Reel) is compatible with assembly processes.
C0805C102K1RAC7800 (KEMET) and CC0805KRX7R0BB102 (YAGEO) provide direct cross-manufacturer substitution with matching 1000 pF ±10% 100V X7R specifications. Both parts are Active status and ROHS3 compliant. Selection between these options depends on supplier availability and established procurement relationships.
For Enhanced Performance (Upgrade Specifications)
CL21B102JCANNNC (Samsung Electro-Mechanics) offers tighter ±5% tolerance while maintaining 100V rating and 0805 package. This upgrade reduces capacitance variation and is suitable for applications requiring improved tolerance performance.
CL21B102KDCNFNC (Samsung Electro-Mechanics) and C0805C102J2RAC7800 (KEMET) provide 200V voltage rating upgrades with maintained or improved tolerance specifications. These parts are suitable for designs requiring higher voltage margins or when circuit requirements increase.
0805AC102KAT1A (KYOCERA AVX) represents a significant voltage upgrade to 1000V (1kV) while maintaining 1000 pF capacitance and X7R temperature coefficient. This part is selected for high-voltage applications or when maximum voltage headroom is required.
Product Status Considerations
GRM219R72A102KA01D (Murata Electronics) carries "Not For New Designs" status. This part remains available for existing inventory and legacy system support but should not be selected for new product development. Active status parts (all other substitutes) are appropriate for new designs.
Compliance and Certification
All recommended substitutes maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring regulatory compatibility and eliminating moisture-related assembly constraints.
Frequently Asked Questions (FAQ)
Q: Can CL21B102KCANNWC be replaced with a part having ±5% tolerance instead of ±10%?
A: Yes. Parts with ±5% tolerance (CL21B102JCANNNC, C0805C102J1RAC7800, C0805C102J2RAC7800) are functional upgrades that provide tighter capacitance control. The ±5% tolerance is a subset of the ±10% specification, ensuring compatibility with any circuit designed for ±10% tolerance.
Q: What is the difference between Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) packaging?
A: Both packaging formats contain identical components on standard 8mm tape. Cut Tape & Digi-Reel® is supplied in cut lengths suitable for manual handling or small-volume assembly. Tape & Reel (TR) is supplied on full reels for automated pick-and-place assembly. Selection depends on assembly process requirements and volume. Electrical and mechanical specifications are identical between packaging formats.
Q: Can CL21B102KCANNWC be replaced with 0805AC102KAT1A (1000V rating)?
A: Yes. The 1000V rated part is a functional upgrade that maintains 1000 pF capacitance, ±10% tolerance, X7R temperature coefficient, and 0805 package. The higher voltage rating provides additional safety margin and is compatible with any circuit designed for 100V or lower. Physical dimensions differ slightly (thickness 0.037" vs. 0.030"), requiring verification of PCB clearance in space-constrained layouts.
Q: Why is GRM219R72A102KA01D marked "Not For New Designs"?
A: "Not For New Designs" status indicates the manufacturer (Murata Electronics) has discontinued active promotion and development of this part number. Existing inventory may remain available for legacy system support and repairs. For new product development, select from Active status alternatives such as C0805C102K1RAC7800 (KEMET) or KGM21NR72A102KT (KYOCERA AVX).
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 regulatory and environmental specifications of the main part CL21B102KCANNWC.
Q: What determines whether a part can substitute for CL21B102KCANNWC?
A: Substitution eligibility requires: (1) Capacitance value of 1000 pF, (2) X7R temperature coefficient, (3) 0805 (2012 Metric) package, (4) Operating temperature range including -55°C to 125°C, (5) Voltage rating ≥100V, (6) Tolerance ≤±10%, (7) ROHS3 compliance, and (8) MSL rating ≤1. Parts meeting these criteria are electrically and mechanically compatible.
Q: Can thickness variation between substitute parts affect PCB assembly?
A: Thickness variations (ranging from 0.028" to 0.039" maximum) are within standard 0805 package specifications. Verify PCB design clearances if components are mounted near tall components or in confined spaces. Standard PCB design practices accommodate this thickness range without modification.
