MSART042SCG010BWRA01 Equivalent & Substitute Parts

Part Overview

The MSART042SCG010BWRA01 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 is currently in Active product status. Equivalent and substitute parts are identified for applications requiring identical electrical and mechanical specifications, particularly when primary inventory availability is limited or when design flexibility permits selection from alternative manufacturers meeting the same parametric requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MSART042SCG010BWRA01 are qualified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters:

Electrical Parameters:

• Capacitance value: 1 pF (exact match required)
• Tolerance: ±0.1pF (exact match required)
• Voltage rating: 25V (exact match required)
• Temperature coefficient: C0G/NP0 (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)

Mechanical Parameters:

• Package type: 01005 (0402 Metric) (exact match required)
• Mounting type: Surface Mount, MLCC (exact match required)
• Physical dimensions: 0.016" L x 0.008" W, 0.009" max thickness (exact match required)

Compliance Parameters:

• RoHS3 compliance (required)
• Moisture Sensitivity Level 1 (required)

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the main part number in applications where the specified parameters are required.

Engineering Selection Recommendations

MSART042SCG010BWRA01 (Primary Part)

• Product Status: Active
• Recommended for new designs and long-term production applications
• Taiyo Yuden MSAR series provides current manufacturing support and availability

TVS042CG010BC-W (Taiyo Yuden Substitute)

• Product Status: Not For New Designs
• Electrically and mechanically equivalent to the primary part
• Suitable for legacy design support and existing production lines only
• Not recommended for new design implementations

KGM02ACG1E1R0BH (KYOCERA AVX Substitute)

• Product Status: Active
• Electrically and mechanically equivalent to the primary part
• KYOCERA AVX KGM series provides current manufacturing support
• Suitable for new designs and production applications
• REACH Unaffected status provides additional compliance documentation

For new designs, selection between MSART042SCG010BWRA01 and KGM02ACG1E1R0BH is based on supply chain strategy, manufacturer preference, and inventory availability. Both parts maintain Active product status and full compliance certifications. The TVS042CG010BC-W substitute is limited to legacy applications due to its Not For New Designs status.

Frequently Asked Questions (FAQ)

Q: Can TVS042CG010BC-W be used as a direct replacement for MSART042SCG010BWRA01 in new designs?

A: No. TVS042CG010BC-W carries a "Not For New Designs" product status. While it is electrically and mechanically equivalent, it is restricted to legacy applications and existing production support only. For new designs, use MSART042SCG010BWRA01 or KGM02ACG1E1R0BH.

Q: Are KGM02ACG1E1R0BH and MSART042SCG010BWRA01 pin-compatible?

A: Yes. Both parts share identical package specifications (01005/0402 Metric), physical dimensions (0.016" L x 0.008" W), and mounting type (Surface Mount, MLCC). They are mechanically and electrically interchangeable in PCB layouts designed for either part.

Q: What is the difference between C0G and NP0 temperature coefficients?

A: C0G and NP0 designations refer to the same temperature coefficient characteristic and are used interchangeably by different manufacturers. All three substitute parts in this reference use C0G/NP0 designation, indicating zero temperature coefficient performance across the -55°C to 125°C operating range.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. MSART042SCG010BWRA01, TVS042CG010BC-W, and KGM02ACG1E1R0BH are all ROHS3 Compliant. All parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements.

Q: What is the significance of the 1 pF ±0.1pF tolerance specification?

A: The ±0.1pF tolerance represents the maximum allowable deviation from the nominal 1 pF capacitance value. This tight tolerance is critical for high-frequency and RF applications where precise capacitance values are required for circuit tuning and impedance matching. All substitute parts maintain this identical tolerance specification.

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

A: Yes, from an electrical and mechanical standpoint. All three parts meet the same electrical specifications (1 pF, 25V, C0G/NP0) and physical requirements (01005 package). However, TVS042CG010BC-W is designated for RF and Microwave applications in its product description, while MSART042SCG010BWRA01 and KGM02ACG1E1R0BH are designated for General Purpose applications. For new RF/microwave designs, consult application-specific guidance from the respective manufacturers.

Q: What inventory considerations should be evaluated when selecting between substitute parts?

A: MSART042SCG010BWRA01 has 809 pcs in stock, TVS042CG010BC-W has 80,680 pcs in stock, and KGM02ACG1E1R0BH has 20,501 pcs in stock. Inventory levels should be balanced against product status restrictions and long-term supply chain strategy. TVS042CG010BC-W's higher inventory does not offset its "Not For New Designs" status for new applications.
