MSART042SCG2R4AWRA01 Equivalent & Substitute Parts

Part Overview

The MSART042SCG2R4AWRA01 is a 2.4 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 maintains Active product status and is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Equivalent and substitute parts are identified based on matching electrical specifications, mechanical dimensions, and packaging compatibility. Substitute parts enable procurement flexibility when the primary part number is unavailable or when alternative packaging formats are acceptable for the application.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MSART042SCG2R4AWRA01 are qualified based on the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 2.4 pF
• Tolerance: ±0.05pF
• Voltage rating: 25V
• Temperature coefficient: C0G/NP0
• Operating temperature range: -55°C ~ 125°C

Mechanical Equivalence Criteria:

• 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)

Compliance Criteria:

• RoHS3 compliance
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts may differ in packaging format (Tape & Reel versus Cut Tape) and product status, provided all electrical and mechanical parameters remain identical. Packaging format differences do not affect functional compatibility in the application circuit.

Engineering Selection Recommendations

Primary Selection: MSART042SCG2R4AWRA01

The MSART042SCG2R4AWRA01 is the recommended choice for new designs. This part maintains Active product status, ensuring long-term availability and manufacturing support. It is supplied in Tape & Reel (TR) packaging, which is standard for automated assembly processes. ROHS3 compliance and MSL 1 rating confirm suitability for standard manufacturing and storage conditions.

Secondary Selection: CQ0100ARNPO8BN2R4

The CQ0100ARNPO8BN2R4 (YAGEO) is a functionally equivalent alternative with Active product status. All electrical and mechanical parameters match the primary part. This part is available in higher inventory quantities (20,553 pcs) and is supplied in Tape & Reel (TR) packaging. The High Q feature designation does not alter electrical equivalence for the specified parameters.

Tertiary Selection: TMK042CG2R4AD-W

The TMK042CG2R4AD-W (Taiyo Yuden) is electrically and mechanically equivalent but carries Not For New Designs product status. This part is supplied in Cut Tape (CT) packaging rather than Tape & Reel format. Use of this part is limited to legacy system maintenance or applications where Cut Tape packaging is acceptable. The different packaging format may require manual handling or alternative assembly processes.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG2R4AD-W be used as a direct replacement for MSART042SCG2R4AWRA01?

A: Yes, from an electrical and mechanical standpoint. Both parts have identical capacitance (2.4 pF), tolerance (±0.05pF), voltage rating (25V), temperature coefficient (C0G/NP0), and physical dimensions (01005/0402 Metric). The primary difference is packaging format: TMK042CG2R4AD-W is supplied in Cut Tape (CT) while MSART042SCG2R4AWRA01 is supplied in Tape & Reel (TR). Additionally, TMK042CG2R4AD-W carries Not For New Designs status, making it unsuitable for new product development.

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

A: Tape & Reel (TR) packaging supplies components on a continuous reel suitable for automated pick-and-place assembly equipment. Cut Tape (CT) packaging supplies components on tape segments, typically requiring manual handling or specialized equipment. Both formats contain identical components; the difference is in delivery and handling method.

Q: Are all three substitute parts suitable for high-reliability applications?

A: MSART042SCG2R4AWRA01 and CQ0100ARNPO8BN2R4 are both Active products with ROHS3 compliance and MSL 1 rating, making them suitable for high-reliability applications. TMK042CG2R4AD-W, while electrically equivalent, carries Not For New Designs status and should not be selected for new high-reliability applications.

Q: Does the High Q feature of CQ0100ARNPO8BN2R4 affect its substitutability?

A: No. The High Q designation indicates superior quality factor characteristics but does not alter the core electrical parameters (capacitance, tolerance, voltage rating, temperature coefficient) that determine substitutability. The part remains functionally equivalent for applications requiring the specified 2.4 pF, 25V, C0G/NP0 capacitor.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes, provided the assembly process accommodates the packaging format. MSART042SCG2R4AWRA01 and CQ0100ARNPO8BN2R4 are both supplied in Tape & Reel format and are directly compatible with standard automated assembly lines. TMK042CG2R4AD-W in Cut Tape format requires manual placement or alternative assembly equipment.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity limitations. These parts do not require special moisture-controlled storage or handling procedures and can be stored under standard warehouse conditions indefinitely without degradation.
