CL10B221KB8NNWC Equivalent & Substitute Parts

Part Overview

The CL10B221KB8NNWC is a 220 pF ±10% 50V ceramic capacitor in X7R temperature coefficient, manufactured by Samsung Electro-Mechanics in 0603 (1608 Metric) surface mount package. This component is Active status and ROHS3 compliant, designed for general purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and performance parameters.

Substitute Part Grouping Explanation

Substitute parts for the CL10B221KB8NNWC are classified based on strict equivalence of the following parameters:

Capacitance value: 220 pF
Tolerance: ±10%
Rated voltage: 50V
Temperature coefficient: X7R
Operating temperature range: -55°C ~ 125°C
Package: 0603 (1608 Metric)
Mounting type: Surface Mount, MLCC
RoHS compliance: ROHS3 Compliant
MSL rating: 1 (Unlimited)

All identified substitutes maintain these electrical and mechanical specifications. Packaging format (Tape & Reel or Cut Tape) does not affect electrical or mechanical compatibility and represents a logistical variation only.

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory conformance. Selection among equivalent parts should be based on:

Inventory availability and supply chain requirements. The CL10B221KB8NFNC variant from Samsung Electro-Mechanics offers the highest inventory level at 208,185 pieces, providing supply continuity for high-volume applications.

Packaging format compatibility with assembly processes. Tape & Reel (TR) packaging is standard for automated pick-and-place operations, while Cut Tape (CT) variants such as 0603B221K500CT accommodate manual or selective assembly workflows.

Manufacturer qualification requirements. Organizations with established supplier relationships may prioritize parts from qualified manufacturers within their approved vendor lists.

All parts maintain identical electrical performance within the specified tolerance and temperature operating range, ensuring functional interchangeability in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can CL10B221KB8NNWC be replaced with any of the listed substitutes without circuit redesign?

A: Yes. All substitute parts maintain identical capacitance (220 pF), tolerance (±10%), rated voltage (50V), temperature coefficient (X7R), and operating temperature range (-55°C ~ 125°C). The 0603 package footprint is identical across all parts, enabling direct PCB layout compatibility.

Q: What is the difference between the Samsung variants CL10B221KB8NNWC, CL10B221KB8NFNC, and CL10B221KB8NNNC?

A: These parts are parametric equivalents from the same manufacturer and series. The differences in part number suffixes reflect internal manufacturing or packaging variations that do not affect electrical or mechanical specifications. All three maintain identical performance characteristics.

Q: Does packaging format (Tape & Reel vs. Cut Tape) affect electrical performance?

A: No. Packaging format is a logistical consideration only and does not impact electrical or mechanical performance. The choice between Tape & Reel and Cut Tape should be based on assembly process requirements and handling procedures.

Q: Are there thickness variations among the substitute parts?

A: Thickness specifications are 0.035" (0.90mm) for most parts, with the Walsin 0603B221K500CT specified at 0.034" (0.87mm). Both values fall within acceptable PCB assembly tolerances for 0603 package components and do not affect circuit functionality or board-level compatibility.

Q: What does MSL 1 (Unlimited) mean for storage and handling?

A: MSL 1 rating indicates the component has unlimited shelf life under standard storage conditions and does not require special moisture control or baking procedures prior to assembly. This simplifies inventory management and reduces handling complexity.
