MSART042SCG020AWRA01 Equivalent & Substitute Parts

Part Overview

The MSART042SCG020AWRA01 is a 2 pF ceramic capacitor manufactured by Taiyo Yuden, rated for 25V with C0G/NP0 temperature coefficient characteristics. This surface-mount multilayer ceramic capacitor (MLCC) is packaged in 01005 (0402 Metric) form factor and is supplied in Tape & Reel (TR) packaging. The part is currently in Active product status with 921 pieces available in stock.

Equivalent and substitute parts are identified when designs require alternative sourcing due to supply constraints, inventory availability, or procurement preferences while maintaining identical electrical and mechanical performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MSART042SCG020AWRA01 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 2 pF
• Tolerance: ±0.05pF
• Voltage rating: 25V
• Temperature coefficient: C0G/NP0

Mechanical Parameters:

• Package type: 01005 (0402 Metric)
• Mounting type: Surface Mount, MLCC
• Physical dimensions: 0.016" L x 0.008" W (0.40mm x 0.20mm)
• Maximum thickness: 0.009" (0.22mm)

Environmental & Compliance Parameters:

• Operating temperature range: -55°C ~ 125°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS3 Compliance

Parts meeting all these parameters are classified as parametric equivalents. Packaging format (Tape & Reel versus Cut Tape) does not affect electrical or mechanical compatibility and represents a procurement variation only.

Engineering Selection Recommendations

MSART042SCG020AWRA01 (Primary Part)

This part is the recommended selection for new designs. It maintains Active product status, ensuring long-term availability and manufacturer support. Supplied in Tape & Reel packaging, it is optimized for automated assembly processes. ROHS3 compliance and MSL 1 rating confirm environmental and handling compatibility with modern manufacturing standards.

TMK042CG020AD-W (Taiyo Yuden Alternative)

This substitute is electrically and mechanically identical to the main part. However, it carries "Not For New Designs" product status, indicating the manufacturer has discontinued active development and support. This part is suitable only for legacy system maintenance, repair, or continuation of existing production runs where design changes are not feasible. The Cut Tape packaging format requires manual handling and is incompatible with high-speed automated assembly equipment. Significantly higher inventory availability (40454 pieces) may support extended production runs of existing designs.

CQ0100ARNPO8BN2R0 (YAGEO Alternative)

This substitute provides full parametric equivalence with Active product status, ensuring ongoing manufacturer support and availability. Manufactured by YAGEO, it represents a cross-manufacturer alternative suitable for new designs. Tape & Reel packaging maintains compatibility with automated assembly processes. The High Q feature designation indicates superior quality factor characteristics, though this does not alter fundamental substitution eligibility. Inventory availability of 21148 pieces supports consistent procurement.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG020AD-W be used in new product designs?

A: TMK042CG020AD-W carries "Not For New Designs" status. While electrically and mechanically equivalent, it is designated for legacy applications only. New designs should use MSART042SCG020AWRA01 or CQ0100ARNPO8BN2R0.

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

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape suitable for automated pick-and-place assembly. Cut Tape (CT) packaging provides components on individual tape segments requiring manual handling. Both formats contain identical components; packaging selection depends on assembly process requirements.

Q: Are all three parts interchangeable on the PCB?

A: Yes. All three parts are parametrically equivalent across electrical specifications (2 pF, ±0.05pF, 25V, C0G/NP0), mechanical dimensions (01005/0402 Metric), and environmental ratings (-55°C ~ 125°C, MSL 1, ROHS3). Direct substitution on the PCB is supported without design modification.

Q: Why does CQ0100ARNPO8BN2R0 list "High Q" as a feature?

A: High Q indicates superior quality factor performance. This characteristic does not affect substitution eligibility, as the part meets all specified electrical and mechanical parameters. It represents an additional performance attribute of the YAGEO component.

Q: Which substitute should be selected for cost optimization?

A: Selection depends on procurement volume and assembly process. TMK042CG020AD-W offers the highest inventory availability but requires manual handling and carries legacy status. CQ0100ARNPO8BN2R0 provides Active status with Tape & Reel compatibility. MSART042SCG020AWRA01 remains the primary recommendation for new designs.

Q: Are there compliance differences between the three parts?

A: All three parts are ROHS3 compliant with MSL 1 rating. TMK042CG020AD-W includes REACH Unaffected designation. Compliance profiles are equivalent for standard manufacturing and deployment environments.
