CL31B474KBHNNNF Equivalent & Substitute Parts

Part Overview

The CL31B474KBHNNNF is a 0.47 µF ±10% 50V ceramic capacitor manufactured by Samsung Electro-Mechanics in the 1206 (3216 Metric) package with X7R temperature coefficient. This multilayer ceramic capacitor (MLCC) is designed for general-purpose applications and is currently in active product status with 871 pieces in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required, or when design specifications allow for compatible alternatives from different manufacturers. This reference provides direct equivalents and parametric substitutes that maintain electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts are classified into three categories based on their relationship to the main part CL31B474KBHNNNF:

Parametric Equivalents maintain identical electrical specifications (0.47 µF, ±10%, 50V, X7R, -55°C ~ 125°C) and mechanical compatibility (1206 package, surface mount). These parts differ only in packaging format (Cut Tape vs. Tape & Reel) or minor manufacturing variations. Parametric equivalents include CL31B474KBHNNNE from Samsung Electro-Mechanics.

Direct Equivalents from alternative manufacturers meet all core electrical and mechanical parameters: 0.47 µF capacitance, ±10% tolerance, 50V voltage rating, X7R temperature coefficient, 1206 package, and surface mount configuration. These parts are sourced from KEMET, YAGEO, Murata Electronics, KYOCERA AVX, and Taiyo Yuden. Direct equivalents may have minor variations in thickness or specific application focus (bypass/decoupling, general purpose, SMPS filtering) but maintain full electrical compatibility.

Upgrade Parts from Samsung Electro-Mechanics and YAGEO add automotive-grade certifications (AEC-Q200) and open-mode failure characteristics while maintaining the same core electrical specifications. These are suitable for applications requiring higher reliability standards.

Voltage-Upgraded Parts such as CGJ5L2X7R2A474K160AA from TDK Corporation provide 100V rating instead of 50V, offering higher voltage margin while maintaining all other parameters. These are suitable for applications where higher voltage headroom is beneficial.

Frequently Asked Questions (FAQ)

Q: Can I substitute CL31B474KBHNNNF with a part having different capacitance value?

A: No. Capacitance must remain at 0.47 µF for circuit function. Different capacitance values alter frequency response, filtering characteristics, and circuit timing. Only parts explicitly listed with 0.47 µF are acceptable substitutes.

Q: What is the difference between CL31B474KBHNNNF and CL31B474KBHNNNE?

A: Both are Samsung Electro-Mechanics parts with identical electrical specifications (0.47 µF, ±10%, 50V, X7R). The difference is packaging format: CL31B474KBHNNNF is supplied in Tape & Reel (TR) format, while CL31B474KBHNNNE is supplied in Cut Tape (CT) & Digi-Reel format. Selection depends on assembly equipment compatibility.

Q: Can I use CGJ5L2X7R2A474K160AA as a direct replacement?

A: CGJ5L2X7R2A474K160AA is a voltage-upgraded equivalent with 100V rating instead of 50V. It is electrically compatible and provides higher voltage margin. However, this part is obsolete. Use only if existing inventory is available and supply continuity is not required. For new designs, select from active-status alternatives.

Q: Are automotive-grade parts (AEC-Q200) compatible with general-purpose applications?

A: Yes. Automotive-grade parts such as CL31B474KBHWPNE and AC1206KKX7R9BB474 meet or exceed general-purpose requirements. They include additional reliability testing and open-mode failure characteristics. Using automotive-grade parts in general-purpose applications provides enhanced reliability without compatibility issues.

Q: What does "Not For New Designs" mean?

A: Parts marked "Not For New Designs" (GRM31MR71H474KA01L, UMK316B7474KL-T, CL31B474KBH5PNE) are in mature or declining production phases. Manufacturers may discontinue these parts with limited notice. These parts are suitable for replacement in existing products but should not be selected for new designs to avoid future supply chain disruptions.

Q: Does thickness variation affect PCB compatibility?

A: Thickness variations (ranging from 0.039" to 0.075") do not affect PCB footprint compatibility, as all parts use the same 1206 (3216 Metric) package. However, thickness may affect clearance in space-constrained designs. KEMET's C1206C474K5RAC7800 (0.039" thickness) is the thinnest option for compact layouts.

Q: Can I mix different manufacturers' parts in the same design?

A: Yes. All listed parts meet identical electrical specifications (0.47 µF, ±10%, 50V, X7R) and mechanical compatibility (1206 package, surface mount). Different manufacturers can be used interchangeably without circuit redesign. Verify supply chain and procurement policies for multi-source strategies.

Q: What is the significance of X7R temperature coefficient?

A: X7R indicates capacitance variation of ±15% across the operating temperature range (-55°C to 125°C). This is a standard specification for general-purpose and automotive applications. All listed substitutes maintain X7R characteristics, ensuring consistent performance across temperature extremes.

Q: Are all parts ROHS3 compliant?

A: Yes. All listed parts maintain ROHS3 compliance and REACH unaffected status, matching regulatory requirements for the original CL31B474KBHNNNF. No additional compliance verification is required when substituting between listed parts.

Q: Which substitute has the highest inventory availability?

A: CL31B474KBHWPNE from Samsung Electro-Mechanics has the highest inventory at 710,903 pieces. This automotive-grade upgrade provides excellent supply security for high-volume production.
