CL31F335ZOFNNNE Equivalent & Substitute Parts

Part Overview

The CL31F335ZOFNNNE is a 3.3 µF ceramic capacitor manufactured by Samsung Electro-Mechanics, rated for 16V operation with Y5V temperature coefficient characteristics. This multilayer ceramic capacitor (MLCC) in 1206 (3216 Metric) package format is designed for general-purpose applications requiring surface mount assembly. The part maintains active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified to provide design flexibility, supply chain alternatives, and equivalent electrical performance across compatible manufacturing sources.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CL31F335ZOFNNNE are qualified based on strict electrical and mechanical parameter matching. The substitution logic requires equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Capacitance: 3.3 µF
• Voltage Rating: 16V
• Tolerance: -20%, +80%
• Temperature Coefficient: Y5V (F)
• Operating Temperature Range: -30°C ~ 85°C

Mechanical Parameters (Must Match Exactly):

• Package / Case: 1206 (3216 Metric)
• Mounting Type: Surface Mount, MLCC

Compliance Parameters (Must Match or Exceed):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: MSL 1 (Unlimited)

All identified substitute parts meet these criteria and are sourced from active product lines with confirmed inventory availability.

Parameter Comparison

Engineering Selection Recommendations

All three parts—CL31F335ZOFNNNE (Samsung Electro-Mechanics), C1206C335Z4VAC7800 (KEMET), and CC1206ZKY5V7BB335 (YAGEO)—are functionally equivalent for circuit applications requiring 3.3 µF, 16V, Y5V ceramic capacitors in 1206 package format.

Selection Criteria Based on Provided Data:

1. Regulatory Compliance: All parts maintain ROHS3 compliance and REACH Unaffected status, meeting international environmental standards.

2. Product Status: All parts are active products with confirmed inventory availability, ensuring long-term supply continuity.

3. Moisture Sensitivity: All parts carry MSL 1 (Unlimited) rating, indicating no special moisture control requirements during storage or handling.

4. Physical Compatibility: All parts share identical external dimensions (0.126" L x 0.063" W) and 1206 package footprint, ensuring direct PCB layout compatibility. Thickness variations (1.40mm, 1.35mm, 1.15mm) remain within acceptable assembly tolerances for standard surface mount processes.

5. Electrical Performance: Identical capacitance, voltage rating, tolerance, temperature coefficient, and operating temperature range ensure equivalent circuit behavior across all three options.

Selection between these parts may be based on supply availability, lead time, packaging format (Tape & Reel for KEMET and YAGEO), or established supplier relationships, as all electrical and mechanical specifications are equivalent.

Frequently Asked Questions (FAQ)

Q: Can C1206C335Z4VAC7800 (KEMET) be used as a direct replacement for CL31F335ZOFNNNE (Samsung)?

A: Yes. Both parts share identical electrical specifications (3.3 µF, 16V, -20%/+80% tolerance, Y5V temperature coefficient, -30°C ~ 85°C operating range) and mechanical compatibility (1206 package, surface mount MLCC). Physical dimensions are identical, and both maintain ROHS3 compliance and MSL 1 rating.

Q: What is the significance of the thickness difference between the three parts?

A: The thickness variations (1.40mm, 1.35mm, 1.15mm) are within standard manufacturing tolerances for 1206 ceramic capacitors. All three parts fit within typical PCB assembly clearances and do not affect electrical performance or circuit functionality.

Q: Are all three parts suitable for the same operating temperature range?

A: Yes. All three parts operate across the identical temperature range of -30°C ~ 85°C with Y5V temperature coefficient characteristics, ensuring consistent capacitance behavior across environmental conditions.

Q: Do packaging differences affect substitution compatibility?

A: The CL31F335ZOFNNNE is supplied in standard packaging, while C1206C335Z4VAC7800 and CC1206ZKY5V7BB335 are supplied in Tape & Reel format. This affects handling and automated assembly processes but does not impact electrical or mechanical compatibility. Component selection should account for existing assembly line equipment and processes.

Q: Are all parts compliant with current environmental regulations?

A: Yes. All three parts are ROHS3 compliant and REACH Unaffected, meeting current international environmental and hazardous substance restrictions.

Q: Can these parts be interchanged mid-production without circuit redesign?

A: Yes. Identical electrical parameters (capacitance, voltage, tolerance, temperature coefficient) and mechanical specifications (1206 package, surface mount) permit direct substitution without circuit redesign or PCB layout modification.
