Substitute Part Grouping Explanation

Substitution eligibility for the CL21B474KBF4PNE is determined by the following critical parameters:

Primary Substitution Criteria:

• Capacitance: 0.47 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating: 50V (minimum requirement; higher ratings acceptable)
• Temperature Coefficient: X7R (exact match required)
• Operating Temperature: -55°C ~ 125°C (exact match required)
• Package: 0805 (2012 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• AEC-Q200 Automotive Rating (required for automotive applications)
• RoHS3 Compliance (required)
• MSL 1 Rating (required)

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

MFR Recommended Substitute: Parts with identical electrical and mechanical specifications but different packaging format or product status upgrade.

Parametric Equivalent: Parts with identical electrical specifications and package, differing only in internal manufacturing codes or packaging reel type.

Direct Manufacturer Equivalent: Parts from alternative manufacturers meeting all electrical, mechanical, and compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: CL21B474KBFVPNE

The CL21B474KBFVPNE is the preferred substitute for the CL21B474KBF4PNE. Both parts are manufactured by Samsung Electro-Mechanics and share identical electrical specifications (0.47 µF, ±10%, 50V, X7R, -55°C ~ 125°C). The CL21B474KBFVPNE carries Active product status, ensuring continued availability and manufacturing support. The only difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel), which does not affect electrical or mechanical performance. Both parts meet AEC-Q200 automotive requirements, ROHS3 compliance, and MSL 1 rating.

Secondary Recommendation: CL21B474KBFVPNG

The CL21B474KBFVPNG is a parametric equivalent with identical electrical and mechanical specifications to the main part. This Samsung Electro-Mechanics part maintains Active product status and full compliance with automotive and environmental standards. Selection of this part is appropriate when inventory or supply chain considerations favor this specific manufacturing code variant.

Alternative Recommendations: C0805X474K5RACAUTO and GCJ21BR71H474KA12L

The KEMET C0805X474K5RACAUTO and Murata GCJ21BR71H474KA12L are direct manufacturer equivalents meeting all electrical, mechanical, and compliance requirements. Both parts are Active status with AEC-Q200 automotive rating and ROHS3 compliance. These alternatives are suitable when Samsung Electro-Mechanics parts are unavailable or when multi-source qualification is required. The KEMET part features soft termination technology; the Murata part also includes soft termination capability, both beneficial for boardflex-sensitive applications.

Not Recommended for Direct Substitution: CL21B474KAF4PNE

The CL21B474KAF4PNE differs in voltage rating (25V versus 50V). While this part shares the same capacitance, tolerance, temperature coefficient, and package, the lower voltage rating makes it unsuitable as a direct substitute in circuits designed for 50V operation. This part may only be used in applications where the circuit voltage requirement is confirmed to be 25V or lower.

Frequently Asked Questions (FAQ)

Q: Can I use CL21B474KAF4PNE as a substitute for CL21B474KBF4PNE?

A: No. The CL21B474KAF4PNE has a 25V voltage rating, while the CL21B474KBF4PNE is rated for 50V. Using a lower-voltage-rated capacitor in a 50V circuit creates reliability and safety risks. Substitution is only valid if the circuit voltage requirement is confirmed to be 25V or lower.

Q: What is the difference between CL21B474KBFVPNE and CL21B474KBF4PNE?

A: Both parts have identical electrical specifications (0.47 µF, ±10%, 50V, X7R). The primary difference is packaging format: CL21B474KBF4PNE uses Tape & Reel (TR) packaging, while CL21B474KBFVPNE uses Cut Tape & Digi-Reel® packaging. Additionally, CL21B474KBFVPNE carries Active product status, ensuring continued manufacturing support. Electrical and mechanical performance are equivalent.

Q: Are KEMET and Murata parts fully compatible with Samsung Electro-Mechanics parts?

A: Yes. The C0805X474K5RACAUTO (KEMET) and GCJ21BR71H474KA12L (Murata) meet all electrical, mechanical, and compliance requirements identical to the CL21B474KBF4PNE. All three manufacturers' parts share the same capacitance (0.47 µF), tolerance (±10%), voltage rating (50V), temperature coefficient (X7R), operating temperature range (-55°C ~ 125°C), package (0805), AEC-Q200 automotive rating, ROHS3 compliance, and MSL 1 rating. These parts are functionally interchangeable in automotive applications.

Q: Does the 0805 package dimension differ between manufacturers?

A: The 0805 (2012 Metric) package specification is standardized across all manufacturers listed. All parts share identical footprint dimensions: 0.079" L × 0.049" W (2.00mm × 1.25mm). Thickness varies slightly between manufacturers (1.10mm to 1.45mm maximum), but all values remain within acceptable PCB assembly tolerances and do not affect electrical performance or board-level compatibility.

Q: What does "Not For New Designs" status mean for the CL21B474KBF4PNE?

A: "Not For New Designs" indicates that Samsung Electro-Mechanics has discontinued this specific part number for new product development. Existing inventory remains available for current production and maintenance, but new designs should transition to active alternatives such as CL21B474KBFVPNE. This status does not affect the performance or reliability of existing stock.

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

A: Yes. All listed substitute parts meet identical electrical, mechanical, and compliance specifications. Multi-source qualification is standard practice in automotive manufacturing. However, verify that your design documentation and supply chain procedures permit cross-manufacturer substitution before implementation.

Q: What is the significance of soft termination in KEMET and Murata parts?

A: Soft termination is a manufacturing feature that reduces mechanical stress on component terminations during PCB assembly and thermal cycling. This feature is particularly beneficial in boardflex-sensitive applications where PCBs experience flexing or vibration. The Samsung Electro-Mechanics CL21B474KBF4PNE does not specify soft termination, but this does not indicate incompatibility; it reflects different manufacturing approaches to achieving the same electrical and mechanical performance.
