Substitute Part Grouping Explanation

Substitution of the CL31B474KBHNFNE is determined by strict equivalence of the following electrical and mechanical parameters:

Critical Parameters for Substitution:

Capacitance: 0.47 µF (exact match required)
Tolerance: ±10% (exact match required)
Voltage Rating: 50V minimum (equal or higher voltage acceptable)
Temperature Coefficient: X7R (exact match required)
Operating Temperature: -55°C to 125°C (exact match required)
Package: 1206 (3216 Metric) (exact match required)
Mounting Type: Surface Mount, MLCC (exact match required)

Packaging Variations: The original part uses standard packaging. Equivalent parts may differ in packaging format (Tape & Reel, Cut Tape, Digi-Reel) without affecting electrical performance.

Product Status Considerations: Parts marked "Not For New Designs" remain electrically equivalent but may have limited availability. Parts marked "Active" are preferred for ongoing production.

Upgrade Paths: Parts with higher voltage ratings (100V vs. 50V) or automotive-grade certifications (AEC-Q200) provide enhanced specifications while maintaining full backward compatibility.

Engineering Selection Recommendations

Primary Equivalent (Same Manufacturer, Active Status): CL31B474KBHWPNE is the recommended equivalent from Samsung Electro-Mechanics. This part maintains identical electrical specifications and is in active product status with the highest inventory availability (710,903 units). The only difference is packaging format (Tape & Reel vs. standard), which does not affect electrical performance.

Cross-Manufacturer Equivalents (Active Status):

C1206C474K5RAC7800 (KEMET): Electrically identical with highest inventory (78,435 units). Suitable for general-purpose bypass and decoupling applications.
KGM31HR71H474KU (KYOCERA AVX): Electrically identical with comparable inventory (25,742 units). Maintains ROHS3 compliance and MSL 1 rating.
CC1206KKX7R9BB474 (YAGEO): Electrically identical, active status. Available in Cut Tape & Digi-Reel format.
AC1206KKX7R9BB474 (YAGEO): Electrically identical with AEC-Q200 automotive certification. Suitable for automotive applications requiring enhanced reliability.

Upgrade Option (Higher Voltage Rating): CGJ5L2X7R2A474K160AA (TDK Corporation) provides 100V rating instead of 50V, offering enhanced voltage margin. This part is electrically compatible but marked obsolete. Use only if higher voltage specification is required and availability can be confirmed.

Not Recommended for New Designs: CL31B474KBH5PNE, GRM31MR71H474KA01L, and UMK316B7474KL-T are marked "Not For New Designs" and should be avoided for ongoing production despite electrical equivalence.

Frequently Asked Questions (FAQ)

Q: Can I substitute CL31B474KBHNFNE with a part having a higher voltage rating? A: Yes. CGJ5L2X7R2A474K160AA (100V) is electrically compatible as it maintains the same capacitance, tolerance, temperature coefficient, and package. Higher voltage ratings provide additional safety margin without affecting circuit performance.

Q: What is the difference between packaging formats (Tape & Reel, Cut Tape, Digi-Reel)? A: Packaging format affects manufacturing and handling processes but does not change electrical specifications. Tape & Reel is suitable for automated pick-and-place assembly. Cut Tape & Digi-Reel is used for manual assembly or lower-volume production. Select based on manufacturing process requirements.

Q: Are parts marked "Not For New Designs" still electrically equivalent? A: Yes, parts such as GRM31MR71H474KA01L and UMK316B7474KL-T are electrically identical to the main part. However, they have limited availability and may be discontinued. Use only for replacement or repair of existing assemblies, not for new product development.

Q: What does AEC-Q200 certification mean? A: AEC-Q200 is an automotive-grade reliability standard. Parts such as AC1206KKX7R9BB474 and CL31B474KBHWPNE with this rating are qualified for automotive applications and undergo enhanced testing for temperature cycling, moisture resistance, and long-term reliability.

Q: Can I use KEMET C1206C474K5RAC7800 as a direct replacement? A: Yes. C1206C474K5RAC7800 is a direct electrical equivalent with identical capacitance, tolerance, voltage, temperature coefficient, and package. It is in active status with high inventory availability.

Q: What is the significance of X7R temperature coefficient? A: X7R indicates the capacitance change over temperature is ±15% across the operating range of -55°C to 125°C. This is a standard specification for general-purpose and industrial applications, ensuring stable performance across the full temperature range.

Q: Are all listed parts ROHS3 compliant? A: Yes, all parts in this equivalency list are ROHS3 compliant and have MSL 1 (Unlimited) moisture sensitivity rating, ensuring compliance with environmental regulations and reliability in standard manufacturing environments.
