MSART042SCG2R4BWRA01 Equivalent & Substitute Parts

Part Overview

The MSART042SCG2R4BWRA01 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 currently in active product status. Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required, or when design revisions necessitate component sourcing from alternative product lines within the same manufacturer's portfolio.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MSART042SCG2R4BWRA01 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 2.4 pF
• Tolerance: ±0.1pF
• Voltage rating: 25V
• Temperature coefficient: C0G/NP0

Mechanical Parameters:

• 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 Parameters:

• RoHS3 compliance
• Moisture Sensitivity Level 1

The substitute part TVS042CG2R4BC-W meets all electrical, mechanical, and compliance requirements. The primary distinction between the main part and its substitute is the packaging format: the MSART042SCG2R4BWRA01 is supplied in Tape & Reel (TR) format, while TVS042CG2R4BC-W is supplied in Cut Tape (CT) format. Both parts are manufactured by Taiyo Yuden and share identical electrical specifications and physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

The MSART042SCG2R4BWRA01 is the recommended primary selection for new designs due to its active product status. This part is fully supported by the manufacturer and represents the current production standard for this capacitance value and specification set.

The TVS042CG2R4BC-W serves as a parametric equivalent for applications where the primary part is unavailable or where Cut Tape packaging is operationally preferred. However, this part carries a "Not For New Designs" status, indicating that the manufacturer does not recommend its use in new product development. This designation reflects the manufacturer's product lifecycle management strategy and does not indicate functional deficiency.

Both parts satisfy identical electrical requirements, mechanical constraints, and regulatory compliance standards. Selection between these parts should be based on:

1. Availability requirements: Use the active-status MSART042SCG2R4BWRA01 for new designs when available.
2. Packaging format: Select based on assembly line equipment compatibility and tape handling requirements.
3. Supply chain continuity: The substitute part may be selected when primary part lead times exceed project requirements.

Frequently Asked Questions (FAQ)

Q: Can TVS042CG2R4BC-W be used as a direct replacement for MSART042SCG2R4BWRA01 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The TVS042CG2R4BC-W meets all electrical specifications (2.4 pF, ±0.1pF, 25V, C0G/NP0), operates across the same temperature range (-55°C ~ 125°C), and shares identical physical dimensions (01005/0402 Metric package). The only difference is the packaging format (Cut Tape versus Tape & Reel).

Q: What is the significance of the "Not For New Designs" status on TVS042CG2R4BC-W?

A: This designation indicates that Taiyo Yuden does not recommend this part for incorporation into newly developed products. However, it remains a valid substitute for existing designs or when the primary part is unavailable. The part continues to meet all specified electrical and compliance requirements.

Q: Are there any compatibility issues with different packaging formats?

A: No compatibility issues exist at the component level. Both Tape & Reel (TR) and Cut Tape (CT) formats contain identical components. The difference is purely in the delivery and handling format. Assembly equipment must be compatible with the selected packaging format, but the installed component performance is identical.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both MSART042SCG2R4BWRA01 and TVS042CG2R4BC-W are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited) ratings. Both parts share identical ECCN (EAR99) and HTSUS (8532.24.0020) classifications.

Q: What is the difference in available inventory between these parts?

A: The MSART042SCG2R4BWRA01 has 794 pieces in stock, while TVS042CG2R4BC-W has 80,387 pieces available. Inventory levels may vary based on current supply conditions and should be verified at the time of procurement.

Q: Can these parts be used interchangeably in RF and microwave applications?

A: Yes. Both parts are suitable for RF, microwave, and high-frequency applications. The C0G/NP0 temperature coefficient ensures stable capacitance across the operating temperature range, which is critical for frequency-dependent circuits. The electrical specifications are identical between both parts.
