CL31F475ZOFNNNE Equivalent & Substitute Parts

Part Overview

The CL31F475ZOFNNNE is a 4.7 µF ceramic capacitor manufactured by Samsung Electro-Mechanics, rated for 16V operation with Y5V temperature coefficient characteristics. This multilayer ceramic capacitor (MLCC) is housed in a 1206 (3216 Metric) surface mount package and is classified as obsolete. Due to its obsolete product status, equivalent and substitute parts from active manufacturers are necessary to maintain design continuity and ensure ongoing component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CL31F475ZOFNNNE is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Capacitance value: 4.7 µF (exact match required)
• Voltage rating: 16V minimum (equal or higher acceptable)
• Temperature coefficient: Y5V (F) for direct equivalents; X7R acceptable for enhanced stability applications
• Package / Case: 1206 (3216 Metric) surface mount form factor
• Mounting type: Surface Mount, MLCC
• RoHS3 compliance and MSL 1 rating

Substitution Categories:

Direct Equivalents maintain identical electrical specifications (4.7 µF, 16V, Y5V, -20%/+80% tolerance) with different manufacturers. These parts are interchangeable without circuit redesign.

Parametric Equivalents maintain the same capacitance, voltage, and package but may feature different temperature coefficients (X7R instead of Y5V) or improved tolerance specifications (±10% instead of -20%/+80%). These parts provide enhanced performance characteristics while maintaining functional compatibility.

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance):

The KGM31AV51C475ZU (KYOCERA AVX) and C1206C475Z4VAC7800 (KEMET) are direct parametric equivalents to the CL31F475ZOFNNNE. Both parts maintain the identical 4.7 µF capacitance, 16V voltage rating, Y5V temperature coefficient, and -20%/+80% tolerance specifications. These parts are suitable for applications requiring exact electrical performance matching. Both substitute parts carry active product status and ROHS3 compliance certification, ensuring long-term availability and regulatory compliance.

For Enhanced Performance Applications:

The CL31B475KAHNNNE (Samsung Electro-Mechanics) provides an alternative with improved specifications: 25V voltage rating (56% higher than the original 16V), X7R temperature coefficient (providing superior temperature stability compared to Y5V), and ±10% tolerance (narrower tolerance band than the original -20%/+80%). This part is suitable for applications where enhanced voltage margin, improved temperature stability, or tighter capacitance tolerance is beneficial. The CL31B475KAHNNNE maintains the same 1206 package form factor and carries active product status.

All substitute parts are ROHS3 compliant with MSL 1 rating, ensuring compatibility with standard manufacturing processes and long-term storage capability.

Frequently Asked Questions (FAQ)

Q: Can the KGM31AV51C475ZU be used as a direct replacement for the CL31F475ZOFNNNE?

A: Yes. The KGM31AV51C475ZU maintains identical electrical specifications: 4.7 µF capacitance, 16V voltage rating, Y5V temperature coefficient, and -20%/+80% tolerance. Both parts are housed in the 1206 (3216 Metric) surface mount package. The primary difference is manufacturer (KYOCERA AVX versus Samsung Electro-Mechanics) and packaging format (Tape & Reel versus Cut Tape). The part is functionally interchangeable without circuit modification.

Q: What is the difference between the Y5V and X7R temperature coefficients?

A: Y5V and X7R are temperature coefficient classifications that define capacitance variation across operating temperature ranges. Y5V exhibits capacitance change of -82% to +22% across the -30°C to +85°C operating range. X7R exhibits capacitance change of ±15% across the -55°C to +125°C operating range. X7R provides superior temperature stability and wider operating temperature range, making it suitable for applications requiring consistent capacitance performance across broader temperature extremes.

Q: Is the CL31B475KAHNNNE compatible with circuits designed for the CL31F475ZOFNNNE?

A: The CL31B475KAHNNNE is mechanically and functionally compatible (same 1206 package, same 4.7 µF capacitance). However, it features different electrical characteristics: 25V voltage rating (versus 16V), X7R temperature coefficient (versus Y5V), and ±10% tolerance (versus -20%/+80%). These differences result in improved performance characteristics. Compatibility depends on circuit design requirements. Applications with 16V maximum voltage specifications will operate safely with the 25V-rated substitute. Applications sensitive to temperature coefficient characteristics should evaluate whether X7R performance is acceptable for the intended application.

Q: Why is the CL31F475ZOFNNNE listed as obsolete?

A: The CL31F475ZOFNNNE is classified as obsolete by Samsung Electro-Mechanics, indicating the manufacturer has discontinued production. Active substitute parts from KYOCERA AVX (KGM31AV51C475ZU) and KEMET (C1206C475Z4VAC7800) provide equivalent electrical performance with ongoing manufacturer support and availability.

Q: What packaging formats are available for substitute parts?

A: The KGM31AV51C475ZU is supplied in Tape & Reel (TR) format. The C1206C475Z4VAC7800 is supplied in Tape & Reel (TR) format. The CL31B475KAHNNNE is available in both Cut Tape (CT) and Digi-Reel® formats. Packaging selection depends on production volume requirements and assembly equipment compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (KGM31AV51C475ZU, C1206C475Z4VAC7800, and CL31B475KAHNNNE) are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). This ensures compatibility with standard manufacturing processes and regulatory requirements.
