MSART042SCG1R1AWRA01 Equivalent & Substitute Parts

Part Overview

The MSART042SCG1R1AWRA01 is a 1.1 pF ceramic capacitor manufactured by Taiyo Yuden, designed for general-purpose applications requiring stable capacitance across temperature variations. This surface-mount multilayer ceramic capacitor (MLCC) features C0G/NP0 temperature coefficient characteristics and operates across a temperature range of -55°C to 125°C at a rated voltage of 25V.

The main part is currently in active product status. Substitute parts become necessary when the primary part experiences supply constraints, inventory limitations, or when design requirements permit alternative packaging formats such as cut tape instead of tape and reel configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MSART042SCG1R1AWRA01 is determined by strict equivalence across the following parameters:

Critical Electrical Parameters:

• Capacitance value: 1.1 pF
• Tolerance: ±0.05pF
• Voltage rating: 25V
• Temperature coefficient: C0G/NP0
• Operating temperature range: -55°C to 125°C

Critical Physical Parameters:

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

Compliance Parameters:

• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)

The substitute part TMK042CG1R1AD-W meets all critical electrical and physical parameters. The primary difference is packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is supplied in Cut Tape (CT) configuration. Both formats contain identical components with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The MSART042SCG1R1AWRA01 is the recommended choice for new designs. This part maintains active product status from Taiyo Yuden, ensuring continued availability and manufacturing support. The Tape & Reel packaging format is optimized for high-volume automated assembly processes.

Substitute Part Selection: The TMK042CG1R1AD-W is electrically and mechanically equivalent to the main part and is suitable for substitution when the primary part is unavailable. However, this part carries a "Not For New Designs" status, indicating that Taiyo Yuden does not recommend its use in new product development. The Cut Tape packaging format may require manual handling or alternative assembly equipment compared to Tape & Reel format.

Compliance Considerations: Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring regulatory compatibility across substitution scenarios. No additional compliance verification is required when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG1R1AD-W be used as a direct replacement for MSART042SCG1R1AWRA01?

A: Yes. Both parts are electrically and mechanically identical. The component specifications, electrical performance, and physical dimensions are equivalent. The only difference is the packaging format: Tape & Reel versus Cut Tape. Substitution is valid from a component performance perspective.

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 alternative assembly processes. Both formats contain identical components with identical electrical specifications.

Q: Why is TMK042CG1R1AD-W marked "Not For New Designs"?

A: This designation indicates that Taiyo Yuden does not recommend this part for new product development. The part remains available for existing designs and legacy applications. For new designs, the MSART042SCG1R1AWRA01 (active status) is the appropriate selection.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts have identical capacitance (1.1 pF), tolerance (±0.05pF), voltage rating (25V), temperature coefficient (C0G/NP0), and operating temperature range (-55°C to 125°C). Electrical performance is equivalent.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant and have identical moisture sensitivity levels (MSL 1 - Unlimited). Regulatory and environmental compliance requirements are met by both parts.

Q: Can I use these parts interchangeably in my assembly process?

A: Electrical and component-level interchangeability is confirmed. However, assembly process compatibility depends on your equipment. If your assembly line uses automated pick-and-place equipment designed for Tape & Reel format, the Cut Tape substitute may require process modifications or manual handling. Verify your assembly equipment specifications before substitution.

Q: What inventory considerations should I account for?

A: The main part (MSART042SCG1R1AWRA01) has 828 pieces in stock. The substitute part (TMK042CG1R1AD-W) has significantly higher inventory at 62,532 pieces. If supply constraints exist for the main part, the substitute offers greater availability.
