MSART042SCG0R2AWRA01 Equivalent & Substitute Parts

Part Overview

The MSART042SCG0R2AWRA01 is a 0.2 pF ceramic capacitor manufactured by Taiyo Yuden, designed for general-purpose applications requiring stable capacitance across a wide temperature range. This surface-mount multilayer ceramic capacitor (MLCC) operates at 25V with C0G/NP0 temperature coefficient characteristics, ensuring minimal capacitance drift from -55°C to 125°C. The part is currently active in production and RoHS3 compliant. Equivalent substitute parts are identified to provide design flexibility, supply chain alternatives, and procurement options while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the MSART042SCG0R2AWRA01 are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic requires exact matching of the following parameters:

• Capacitance Value: 0.2 pF
• Capacitance Tolerance: ±0.05 pF
• Rated Voltage: 25V
• Temperature Coefficient: C0G/NP0
• Operating Temperature Range: -55°C to 125°C
• Package Type: 01005 (0402 Metric)
• Mounting Technology: Surface Mount, MLCC
• Physical Dimensions: 0.016" L x 0.008" W (0.40mm x 0.20mm)
• Maximum Thickness: 0.009" (0.22mm)
• Moisture Sensitivity Level: 1 (Unlimited)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. No deviations from these specifications are permitted for substitution classification.

Parameter Comparison

Engineering Selection Recommendations

Both the MSART042SCG0R2AWRA01 (Taiyo Yuden) and CQ0100ARNPO8BNR20 (YAGEO) are active production parts with identical electrical specifications, mechanical dimensions, and regulatory compliance status. Selection between these parts may be based on:

• Supply Chain Availability: Current inventory levels and lead times from respective manufacturers
• Procurement Preference: Established supplier relationships or preferred vendor agreements
• Application-Specific Features: The YAGEO CQ0100ARNPO8BNR20 is specified with High Q characteristics, which may provide performance advantages in high-frequency or precision resonant circuit applications
• Cost Considerations: Pricing and volume discounts from individual suppliers
• Regulatory Compliance: Both parts meet ROHS3 compliance and carry EAR99 export classification

No electrical or mechanical redesign is required when substituting between these parts. PCB layout, footprint, and assembly processes remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can the CQ0100ARNPO8BNR20 be used as a direct replacement for the MSART042SCG0R2AWRA01?

A: Yes. Both parts are parametric equivalents with identical capacitance (0.2 pF), tolerance (±0.05 pF), voltage rating (25V), temperature coefficient (C0G/NP0), operating temperature range (-55°C to 125°C), and package dimensions (01005/0402 Metric). No circuit modifications or PCB redesign are required.

Q: Are there any differences in physical dimensions between these parts?

A: No. Both parts share identical dimensions: 0.016" L x 0.008" W (0.40mm x 0.20mm) with a maximum thickness of 0.009" (0.22mm). They are fully compatible with the same PCB footprint and assembly equipment.

Q: What does the High Q feature on the YAGEO part mean?

A: High Q indicates lower dielectric losses in the ceramic material, resulting in higher quality factor performance. This characteristic is beneficial in applications requiring precise frequency response, such as RF circuits, oscillators, and high-frequency filtering networks. For general-purpose applications, this feature provides no functional requirement but may offer performance margin.

Q: Are both parts RoHS compliant?

A: Yes. Both the MSART042SCG0R2AWRA01 and CQ0100ARNPO8BNR20 are ROHS3 compliant and carry the same ECCN (EAR99) and HTSUS (8532.24.0020) classifications.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These parts do not require special moisture control during storage, handling, or assembly.

Q: Can these parts be used interchangeably in production?

A: Yes. Both parts meet all electrical and mechanical specifications for direct substitution. Assembly processes, reflow profiles, and handling procedures remain identical. Inventory management systems may track both part numbers separately, but they are functionally interchangeable.
