CL21F155ZOFNNNE Equivalent & Substitute Parts

Part Overview

The CL21F155ZOFNNNE is a 1.5 µF ceramic capacitor manufactured by Samsung Electro-Mechanics, rated for 16V operation with Y5V temperature coefficient characteristics. This surface mount multilayer ceramic capacitor (MLCC) in 0805 (2012 Metric) package is designed for general purpose applications requiring stable capacitance across the -30°C to 85°C operating temperature range. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent substitute parts are identified based on matching electrical specifications, mechanical dimensions, and compliance certifications to ensure direct functional interchangeability in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CL21F155ZOFNNNE are identified through strict alignment with the following critical parameters:

Electrical Specifications: Capacitance value of 1.5 µF, voltage rating of 16V, tolerance of -20% to +80%, and Y5V temperature coefficient are non-negotiable requirements. All substitute parts must demonstrate identical electrical performance across the -30°C to 85°C operating temperature range.

Mechanical Compatibility: The 0805 (2012 Metric) package footprint with dimensions of 0.079" L × 0.049" W (2.00mm × 1.25mm) ensures direct PCB placement compatibility. Thickness variations within component specifications do not affect substitution eligibility provided the part fits within standard 0805 assembly tolerances.

Regulatory and Compliance Requirements: RoHS3 compliance, REACH unaffected status, and MSL 1 rating are mandatory matching criteria. ECCN EAR99 and HTSUS 8532.24.0020 classifications confirm equivalent regulatory standing.

Product Status: All substitute parts maintain Active product status, ensuring continued availability and manufacturing support.

The two identified substitute parts—C0805C155Z4VAC7800 (KEMET) and CC0805ZRY5V7BB155 (YAGEO)—satisfy all substitution criteria and are directly interchangeable with the primary part.

Parameter Comparison

Engineering Selection Recommendations

All three parts—CL21F155ZOFNNNE (Samsung Electro-Mechanics), C0805C155Z4VAC7800 (KEMET), and CC0805ZRY5V7BB155 (YAGEO)—are functionally equivalent and directly substitutable based on matching electrical, mechanical, and compliance specifications.

Samsung CL21F155ZOFNNNE: Primary part with 1,028 units in stock. Maintains Active status with full regulatory compliance. Suitable for immediate deployment in production designs.

KEMET C0805C155Z4VAC7800: Direct substitute with 13,344 units available in Tape & Reel packaging. Identical electrical and mechanical specifications. Thickness specification of 0.035" (0.88mm) is within standard 0805 assembly tolerances. Active product status ensures continued supply chain support.

YAGEO CC0805ZRY5V7BB155: Direct substitute with 24,588 units available in Tape & Reel packaging. Identical electrical and mechanical specifications. Highest inventory availability among all three options. Active product status confirms manufacturing continuity.

Selection among these three parts may be based on supply chain availability, packaging format preference (Tape & Reel), or established supplier relationships, as all three satisfy identical functional and compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can C0805C155Z4VAC7800 (KEMET) be used as a direct replacement for CL21F155ZOFNNNE (Samsung)?

A: Yes. Both parts share identical capacitance (1.5 µF), voltage rating (16V), tolerance (-20%, +80%), temperature coefficient (Y5V), operating temperature range (-30°C to 85°C), package footprint (0805), and compliance certifications (RoHS3, REACH, MSL 1). The parts are directly interchangeable without circuit modification.

Q: What is the significance of the Y5V temperature coefficient?

A: Y5V designates a ceramic capacitor with a temperature coefficient that allows capacitance variation of -82% to +22% across the -30°C to +85°C operating range. This specification is standardized and must match across all substitute parts to ensure consistent circuit performance across the full operating temperature envelope.

Q: Are there physical dimension differences between the three parts?

A: All three parts conform to the 0805 (2012 Metric) package standard with identical length (0.079" / 2.00mm) and width (0.049" / 1.25mm). The KEMET part specifies maximum thickness of 0.035" (0.88mm), while Samsung and YAGEO specifications do not provide thickness data. These variations fall within standard 0805 component tolerances and do not affect PCB assembly compatibility.

Q: What does MSL 1 (Unlimited) moisture sensitivity rating mean?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. This rating applies uniformly across all three substitute parts, simplifying inventory management and supply chain logistics.

Q: Can these parts be used interchangeably in existing production runs?

A: Yes. All three parts maintain Active product status with identical electrical specifications, mechanical compatibility, and regulatory compliance. Substitution between any of these three parts does not require design review or circuit re-qualification.

Q: What packaging formats are available?

A: The KEMET C0805C155Z4VAC7800 and YAGEO CC0805ZRY5V7BB155 are supplied in Tape & Reel (TR) format, standard for automated assembly processes. The Samsung CL21F155ZOFNNNE packaging format is not specified in the provided data but is available in stock.

Q: Are all three parts RoHS3 compliant?

A: Yes. All three parts carry RoHS3 compliance certification and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution.
