MSART042SCG030AWRA01 Equivalent & Substitute Parts

Part Overview

The MSART042SCG030AWRA01 is a 3 pF ceramic capacitor manufactured by Taiyo Yuden, rated for 25V with C0G/NP0 temperature coefficient characteristics. This surface-mount multilayer ceramic capacitor (MLCC) in 01005 (0402 Metric) package is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C.

The main part is currently in Active product status. Equivalent and substitute parts become necessary when addressing supply chain constraints, inventory availability, or when transitioning designs to alternative manufacturer sources while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MSART042SCG030AWRA01 is determined by strict equivalence across the following parameters:

Mandatory Matching Parameters:

• Capacitance: 3 pF
• Tolerance: ±0.05pF
• Voltage Rating: 25V
• Temperature Coefficient: C0G, NP0
• Package / Case: 01005 (0402 Metric)
• Operating Temperature Range: -55°C ~ 125°C
• Mounting Type: Surface Mount, MLCC
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Acceptable Variations:

• Manufacturer identity (different suppliers)
• Packaging format (Tape & Reel vs. Cut Tape)
• Product status (Active vs. Not For New Designs)
• Series designation
• Inventory availability

All identified substitute parts meet these mandatory matching criteria and are therefore electrically and mechanically interchangeable with the main part.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: CQ0100ARNPO8BN3R0 (YAGEO)

The CQ0100ARNPO8BN3R0 is the recommended substitute for new designs and ongoing production. This part maintains Active product status, ensuring long-term availability and manufacturer support. All electrical and mechanical parameters are identical to the main part. The YAGEO CQ series provides equivalent performance with High Q characteristics. Packaging is supplied in Tape & Reel format, compatible with standard pick-and-place assembly processes.

Secondary Substitute: TMK042CG030AD-W (Taiyo Yuden)

The TMK042CG030AD-W is a parametric equivalent from the same manufacturer (Taiyo Yuden). This part carries a "Not For New Designs" product status, indicating it is in mature or declining production phase. Use this substitute only when existing inventory must be consumed or when design continuity with legacy systems is required. Packaging is supplied in Cut Tape format, which may require different handling procedures compared to Tape & Reel packaging.

Compliance Considerations:

All three parts are ROHS3 Compliant and carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage or handling. All parts are classified under ECCN EAR99 and HTSUS 8532.24.0020.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG030AD-W be used as a direct replacement for MSART042SCG030AWRA01?

A: Yes. Both parts are electrically and mechanically identical. The primary difference is product status (Not For New Designs vs. Active) and packaging format (Cut Tape vs. Tape & Reel). For new designs, CQ0100ARNPO8BN3R0 is preferred due to Active status.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, suitable for automated pick-and-place assembly. Cut Tape packaging supplies components on cut segments of carrier tape, typically for manual assembly or lower-volume applications. Both formats contain identical components; the difference is in delivery and handling method.

Q: Are there any performance differences between the Taiyo Yuden and YAGEO versions?

A: No. All three parts meet identical electrical specifications: 3 pF capacitance, ±0.05pF tolerance, 25V rating, C0G/NP0 temperature coefficient, and -55°C to 125°C operating range. The YAGEO CQ0100ARNPO8BN3R0 includes High Q characteristics, which represents an additional performance feature.

Q: What does "Not For New Designs" mean for the TMK042CG030AD-W?

A: This designation indicates the part is in mature production phase and may have limited availability or planned discontinuation. While the part remains functional and compliant, manufacturers recommend using Active status alternatives for new product development to ensure long-term supply chain stability.

Q: Can these parts be used interchangeably in existing assemblies?

A: Yes. All three parts are pin-compatible, package-compatible, and electrically equivalent. No circuit modifications or assembly process changes are required when substituting between these parts.

Q: What is the significance of Moisture Sensitivity Level 1?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. These parts do not require special dry-pack storage, desiccant handling, or bake-out procedures before soldering. Standard storage conditions are acceptable.

Q: Are all three parts RoHS compliant?

A: Yes. All three parts are ROHS3 Compliant, meeting the Restriction of Hazardous Substances Directive requirements for lead-free and restricted substance content.
