Substitute Part Grouping Explanation

Substitution of the MSART042SCG1R8BWRA01 is determined by strict equivalence across the following parameters:

Electrical Parameters:

• Capacitance value: 1.8 pF
• Tolerance: ±0.1 pF
• Voltage rating: 25V
• Temperature coefficient: C0G/NP0

Mechanical Parameters:

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

Environmental & Compliance Parameters:

• Operating temperature range: -55°C to 125°C
• Moisture sensitivity level: 1 (Unlimited)

The substitute part CQ0100BRNPO8BN1R8 from YAGEO meets all specified parameters and is therefore electrically and mechanically interchangeable.

Parameter Comparison

Engineering Selection Recommendations

The MSART042SCG1R8BWRA01 and CQ0100BRNPO8BN1R8 are direct parametric equivalents. Both components are Active products with ROHS3 compliance and identical electrical, mechanical, and environmental specifications.

Selection between these parts should be based on:

Availability: The YAGEO CQ0100BRNPO8BN1R8 maintains higher inventory levels (20,659 pcs) compared to the Taiyo Yuden MSART042SCG1R8BWRA01 (747 pcs), making it suitable for high-volume production requirements.

Manufacturer Preference: Both manufacturers produce components meeting identical specifications. Component selection may be driven by existing supply chain relationships, qualification requirements, or procurement policies.

Compliance Status: Both parts maintain ROHS3 compliance and identical export classification (EAR99), ensuring regulatory equivalence for all markets and applications.

Frequently Asked Questions (FAQ)

Q: Can CQ0100BRNPO8BN1R8 be used as a direct replacement for MSART042SCG1R8BWRA01?

A: Yes. Both parts are electrically and mechanically identical. They share the same capacitance value (1.8 pF), tolerance (±0.1 pF), voltage rating (25V), temperature coefficient (C0G/NP0), operating temperature range (-55°C to 125°C), package type (01005/0402 Metric), and physical dimensions. No circuit modifications are required.

Q: Are there any differences in performance characteristics between these two parts?

A: Both parts meet identical electrical specifications. The YAGEO CQ0100BRNPO8BN1R8 is noted to feature High Q characteristics, which represents an additional performance attribute not specified for the Taiyo Yuden part. This does not create incompatibility; it indicates the YAGEO part meets or exceeds the original specification.

Q: What is the significance of the C0G/NP0 temperature coefficient?

A: C0G (also designated NP0) indicates zero temperature coefficient, meaning capacitance remains stable across the operating temperature range of -55°C to 125°C. This characteristic is critical for precision applications requiring consistent capacitance values regardless of ambient temperature variations.

Q: Are both parts suitable for tape and reel packaging?

A: Yes. Both MSART042SCG1R8BWRA01 and CQ0100BRNPO8BN1R8 are supplied in Tape & Reel (TR) packaging, which is standard for automated surface mount assembly processes.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. No baking or desiccant storage is necessary prior to assembly.

Q: Can these parts be used interchangeably in existing designs without re-qualification?

A: Both parts are parametrically equivalent across all specified electrical, mechanical, and environmental parameters. Design re-qualification is not required based on parametric equivalence. However, component substitution policies specific to your organization or application may apply.
