CL03A105MR3CSNC Equivalent & Substitute Parts

Part Overview

The CL03A105MR3CSNC is a 1 µF ceramic capacitor manufactured by Samsung Electro-Mechanics, rated for 4V operation with X5R temperature coefficient characteristics. This surface mount multilayer ceramic capacitor (MLCC) in 0201 package format is designed for general purpose applications requiring stable capacitance across the operating temperature range of -55°C to 85°C. The part is ROHS3 compliant and carries unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified based on matching or exceeding the electrical and mechanical specifications of the main part. Substitutes are organized by their relationship to the original specification: direct equivalents sharing identical ratings, and upgrade alternatives offering enhanced voltage ratings or improved tolerance specifications while maintaining physical compatibility and core electrical characteristics.

Substitute Part Grouping Explanation

Substitution logic for the CL03A105MR3CSNC is based on the following criteria:

Electrical Compatibility: All substitute parts maintain 1 µF capacitance and X5R temperature coefficient. Voltage rating substitutes must equal or exceed the 4V specification. Tolerance variations (±10% or ±20%) are acceptable as they represent different precision grades of the same capacitor value.

Physical Compatibility: All substitutes use identical 0201 (0603 Metric) package dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm), ensuring direct PCB footprint compatibility. Thickness variations within 0.013" to 0.014" maximum are within acceptable assembly tolerances.

Environmental & Compliance: All substitutes maintain ROHS3 compliance, MSL 1 rating, and -55°C to 85°C operating temperature range, ensuring equivalent reliability and regulatory acceptance.

Packaging Format: Substitutes are available in multiple packaging options (Tape & Reel, Cut Tape & Digi-Reel) to accommodate different procurement and assembly workflows.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (4V Rating):

CC0201MRX5R4BB105 (YAGEO) is an active product offering direct electrical and mechanical equivalence to CL03A105MR3CSNC. Both parts share identical 1 µF capacitance, 4V voltage rating, ±20% tolerance, and X5R temperature coefficient. YAGEO's part is available in Tape & Reel packaging and maintains full ROHS3 compliance and MSL 1 rating. This part is suitable for new designs requiring direct replacement.

AMK063ABJ105MP-F (Taiyo Yuden) provides electrical equivalence but carries "Not For New Designs" product status. While the part meets all electrical and mechanical specifications, its discontinued design status makes it unsuitable for new product development. Existing inventory may be used for legacy system support or repair applications only.

Upgrade Alternatives (Higher Voltage Ratings):

CL03A105MQ3CSNC and CL03A105MQ3CSNH (Samsung Electro-Mechanics, 6.3V rating) offer voltage margin improvement over the original 4V specification while maintaining identical capacitance and tolerance. Both parts are active products with extensive inventory availability. The choice between CSNC (Tape & Reel) and CSNH (Cut Tape & Digi-Reel) depends on procurement and assembly requirements.

CL03A105KQ3CSNC and CL03A105KQ3CSNH (Samsung Electro-Mechanics, 6.3V rating, ±10% tolerance) provide both voltage upgrade and improved tolerance specification. The tighter ±10% tolerance may benefit applications requiring enhanced capacitance accuracy. Both are active products with high inventory levels.

CL03A105MP3NSNC (Samsung Electro-Mechanics, 10V rating) represents the maximum voltage upgrade option within the Samsung CL series, offering substantial voltage margin for applications requiring additional safety factor. This part maintains ±20% tolerance matching the original specification.

KGM03BR50J105MH (KYOCERA AVX, 6.3V rating) provides cross-manufacturer equivalence with 6.3V upgrade capability. This part is an active product suitable for applications where multi-source qualification is required.

All upgrade alternatives maintain full ROHS3 compliance, MSL 1 rating, and -55°C to 85°C operating temperature range, ensuring equivalent regulatory and environmental performance.

Frequently Asked Questions (FAQ)

Q: Can I use a 6.3V rated capacitor in place of the 4V CL03A105MR3CSNC?

A: Yes. Higher voltage-rated capacitors are electrically compatible substitutes. A 6.3V capacitor operates safely in a 4V application. The higher voltage rating provides additional safety margin and does not affect circuit performance when capacitance and temperature coefficient specifications match.

Q: What is the difference between ±10% and ±20% tolerance capacitors?

A: Tolerance specifies the allowable deviation from the nominal 1 µF value. A ±20% part can range from 0.8 µF to 1.2 µF, while a ±10% part ranges from 0.9 µF to 1.1 µF. Applications requiring tighter capacitance accuracy should specify ±10% parts. General purpose applications typically accept ±20% tolerance.

Q: Are the different packaging formats (Tape & Reel vs. Cut Tape & Digi-Reel) electrically different?

A: No. Packaging format affects procurement and assembly logistics only. Tape & Reel (TR) and Cut Tape & Digi-Reel (CT) formats contain identical components with different delivery methods. Selection depends on manufacturing equipment compatibility and order quantity requirements.

Q: Why is AMK063ABJ105MP-F marked "Not For New Designs"?

A: This product status indicates the manufacturer has discontinued active development and recommends against use in new product designs. Existing inventory may be available for legacy system support or repair applications, but new designs should specify active products such as CC0201MRX5R4BB105 or Samsung CL series alternatives.

Q: Can I substitute a Samsung part with a YAGEO or KYOCERA AVX part?

A: Yes, provided electrical and mechanical specifications match. CC0201MRX5R4BB105 (YAGEO) and KGM03BR50J105MH (KYOCERA AVX) are cross-manufacturer equivalents meeting identical electrical ratings and package specifications. Cross-manufacturer substitution is acceptable when all critical parameters align and both suppliers maintain equivalent compliance certifications.

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

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. This rating eliminates the need for dry-pack storage or baking procedures prior to assembly, simplifying procurement and manufacturing logistics.

Q: Are all listed substitutes ROHS3 compliant?

A: Yes. All parts in this reference maintain ROHS3 compliance, ensuring regulatory acceptance in applications subject to RoHS Directive requirements. Compliance status is consistent across all substitute options.
