MSART042SCG010AWRA01 Equivalent & Substitute Parts

Part Overview

The MSART042SCG010AWRA01 is a 1 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 supplied in Tape & Reel (TR) configuration. The part maintains Active product status and is RoHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity protection.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when alternative packaging formats better suit manufacturing requirements. The substitute parts listed maintain electrical and mechanical equivalence to the main part while offering different availability profiles or packaging options.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MSART042SCG010AWRA01 is determined by strict equivalence across the following parameters:

Mandatory Matching Parameters:

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

Variable Parameters (Non-Substitution Limiting):

• Packaging format (Tape & Reel, Cut Tape, or Digi-Reel)
• Product status (Active or Not For New Designs)
• Manufacturer identity
• Inventory availability

The two substitute parts identified—TMK042CG010AD-W and CQ0100ARNPO8BN1R0—meet all mandatory matching parameters and are therefore electrically and mechanically interchangeable with the main part.

Parameter Comparison

Engineering Selection Recommendations

MSART042SCG010AWRA01 (Primary Part)

Select this part for new designs and applications requiring long-term supply assurance. The Active product status indicates ongoing manufacturer support and availability. Tape & Reel packaging is optimized for high-volume automated assembly processes. Current inventory of 1014 pieces supports immediate procurement.

TMK042CG010AD-W (Taiyo Yuden Substitute)

This part is electrically and mechanically equivalent but carries Not For New Designs status. Use this substitute only when the primary part is unavailable and existing designs require component replacement. Cut Tape packaging may require manual handling or alternative feeder compatibility. Significantly higher inventory (95804 pieces) indicates potential availability advantage during supply constraints.

CQ0100ARNPO8BN1R0 (YAGEO Substitute)

This part maintains Active product status and is suitable for new designs as an alternative to the primary part. Manufactured by YAGEO, it provides supply diversification from a different manufacturer. Cut Tape and Digi-Reel packaging options offer flexibility for various assembly environments. Inventory of 20189 pieces supports consistent availability.

All three parts satisfy RoHS3 compliance and MSL 1 requirements, ensuring regulatory and environmental handling compatibility across substitution scenarios.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG010AD-W be used as a direct replacement for MSART042SCG010AWRA01?

A: Yes. Both parts are electrically and mechanically equivalent, meeting identical specifications for capacitance (1 pF), tolerance (±0.05pF), voltage rating (25V), temperature coefficient (C0G/NP0), operating temperature range (-55°C ~ 125°C), and package form factor (01005/0402 Metric). The primary difference is packaging format (Cut Tape versus Tape & Reel) and product status (Not For New Designs versus Active).

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, optimized for automated pick-and-place assembly. Cut Tape packaging provides components on shorter tape segments, typically used for manual handling or lower-volume assembly. Both formats contain identical components; packaging selection depends on assembly process requirements.

Q: Is CQ0100ARNPO8BN1R0 suitable for new product designs?

A: Yes. CQ0100ARNPO8BN1R0 maintains Active product status and meets all electrical and mechanical specifications required for the application. As a YAGEO-manufactured alternative, it provides supply chain diversification while maintaining full compatibility with designs specified for MSART042SCG010AWRA01.

Q: Do all three parts comply with RoHS3 requirements?

A: Yes. MSART042SCG010AWRA01, TMK042CG010AD-W, and CQ0100ARNPO8BN1R0 are all RoHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, ensuring equivalent regulatory and environmental handling requirements.

Q: What does "Not For New Designs" status mean for TMK042CG010AD-W?

A: This status indicates the manufacturer (Taiyo Yuden) is not recommending this part for new product development. However, it remains electrically and mechanically equivalent and is suitable for replacement in existing designs or when primary parts are unavailable. For new designs, MSART042SCG010AWRA01 (Active status) or CQ0100ARNPO8BN1R0 (Active status) are preferred selections.

Q: Are there any performance differences between the three parts?

A: No. All three parts meet identical electrical specifications: 1 pF capacitance, ±0.05pF tolerance, 25V voltage rating, C0G/NP0 temperature coefficient, and -55°C ~ 125°C operating temperature range. Performance in circuit operation is equivalent across all three parts.

Q: Can packaging format affect circuit performance?

A: No. Packaging format (Tape & Reel, Cut Tape, or Digi-Reel) affects only the supply and assembly process, not the electrical or mechanical performance of the component itself. Once soldered to the PCB, all three parts function identically.
