CL21B472KBANNWC Equivalent & Substitute Parts

Part Overview

The CL21B472KBANNWC is a 4700 pF ±10% 50V ceramic capacitor manufactured by Samsung Electro-Mechanics in the 0805 (2012 Metric) surface mount package. This multilayer ceramic capacitor (MLCC) with X7R temperature coefficient is classified as Active product status and is suitable for general purpose applications. The part is ROHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity protection.

Equivalent and substitute parts are identified based on matching or exceeding critical electrical parameters: capacitance value, voltage rating, tolerance, temperature coefficient, package form factor, and mounting type. Substitutes are categorized as direct equivalents (identical specifications), parametric equivalents (same voltage and tolerance), or upgrades (higher voltage or tighter tolerance ratings).

Substitute Part Grouping Explanation

Substitute parts are organized into three categories based on substitution logic:

Direct Equivalents share identical electrical specifications with the main part: 4700 pF capacitance, ±10% tolerance, 50V voltage rating, X7R temperature coefficient, and 0805 package. These parts are interchangeable without circuit redesign. Manufacturers include KEMET, YAGEO, KYOCERA AVX, and Vishay Vitramon.

Parametric Equivalents maintain the same voltage rating and capacitance but may differ in packaging variant or internal construction code. The Samsung CL21B472KBANNNC represents a parametric equivalent with identical electrical performance and package specifications.

Upgrade Parts provide higher voltage ratings (100V, 200V, 250V) or tighter tolerance (±5%) while maintaining 4700 pF capacitance and 0805 package form factor. These parts can replace the main part in applications where circuit design permits higher voltage margins or improved tolerance performance. Upgrades are suitable when component availability or reliability requirements necessitate higher-rated alternatives.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and surface mount assembly compatibility.

Engineering Selection Recommendations

Direct Equivalent Selection: Parts CL21B472KBANNNC, C0805C472K5RAC7800, CC0805KRX7R9BB472, KGM21NR71H472KT, and VJ0805Y472KXAAC are direct electrical equivalents suitable for one-to-one replacement. All maintain Active product status and ROHS3 compliance. Selection among these parts should consider:

Inventory availability and supply chain continuity. The YAGEO CC0805KRX7R9BB472 offers the highest inventory level (77300 Pcs), providing supply security. The KEMET C0805C472K5RAC7800 provides 289304 Pcs in stock.

Physical dimensions and PCB layout constraints. The YAGEO part features the minimum thickness (0.024"), suitable for space-constrained applications. The Vishay Vitramon VJ0805Y472KXAAC has maximum thickness (0.057"), requiring verification of available board clearance.

Packaging format. KEMET and YAGEO supply Tape & Reel (TR) format; Samsung and KYOCERA AVX offer Cut Tape (CT) & Digi-Reel® options. Packaging selection depends on assembly equipment and volume requirements.

Upgrade Part Selection: Higher voltage-rated parts (CL21B472KDCNNNC at 200V, C0805C472J1RAC7800 at 100V, C0805C472J2RAC7800 at 200V, 0805PC472KAT1A at 250V) are suitable when circuit design permits voltage margin improvement or when tighter tolerance (±5%) is required. These upgrades maintain 0805 package compatibility and ROHS3 compliance. Upgrade parts are appropriate for:

Applications requiring enhanced reliability margins through higher voltage derating.

Designs where ±5% tolerance (KEMET parts) improves circuit performance compared to ±10% tolerance.

Supply chain optimization when higher-voltage variants offer superior inventory availability.

All substitute parts are ROHS3 compliant with MSL 1 rating, ensuring compatibility with standard surface mount assembly processes and environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage-rated capacitor as a direct replacement?

A: Yes. A 100V, 200V, or 250V rated capacitor can replace the 50V CL21B472KBANNWC in the same circuit. Higher voltage ratings provide additional safety margin and do not degrade circuit performance. The capacitance value (4700 pF) and temperature coefficient (X7R) remain the same, ensuring electrical compatibility.

Q: What is the difference between ±10% and ±5% tolerance parts?

A: Tolerance specifies the acceptable deviation from the nominal 4700 pF value. ±10% tolerance allows deviation from 4230 pF to 5170 pF. ±5% tolerance restricts deviation to 4465 pF to 4935 pF. Tighter ±5% tolerance (KEMET C0805C472J series) is suitable for precision circuits where capacitance accuracy is critical. General purpose applications typically accept ±10% tolerance.

Q: Are all substitute parts physically interchangeable on the PCB?

A: All substitute parts use the 0805 (2012 Metric) package with identical length (0.079") and width (0.049"). Thickness varies from 0.024" to 0.057". Verify available vertical clearance on the PCB before selecting parts with maximum thickness (Vishay Vitramon at 0.057"). Pad layout and solder reflow profiles remain identical across all substitutes.

Q: What packaging formats are available?

A: Substitute parts are supplied in two formats: Cut Tape (CT) & Digi-Reel® (Samsung, YAGEO, KYOCERA AVX) and Tape & Reel (TR) (KEMET, KYOCERA AVX, Vishay Vitramon). Cut Tape format is suitable for small-volume or manual assembly. Tape & Reel format is optimized for automated pick-and-place assembly equipment. Select packaging based on production volume and assembly process.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All substitute parts listed are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. All parts are classified as Active product status. REACH compliance status is consistent across all parts (REACH Unaffected or REACH info available upon request). All parts carry EAR99 ECCN classification and 8532.24.0020 HTSUS code.

Q: Which substitute offers the best inventory availability?

A: The KEMET C0805C472K5RAC7800 provides the highest inventory (289304 Pcs), followed by YAGEO CC0805KRX7R9BB472 (77300 Pcs) and KYOCERA AVX KGM21NR71H472KT (58052 Pcs). For immediate availability with identical specifications, these three parts are recommended.

Q: Can I mix different manufacturers in the same production batch?

A: Yes. All substitute parts meet identical electrical specifications (4700 pF, ±10%, 50V, X7R, 0805 package) and compliance standards. Mixing manufacturers is acceptable from an electrical and mechanical standpoint. However, document manufacturer selection in bill of materials (BOM) for traceability and quality control purposes.
