MSART042SCG2R9AWRA01 Equivalent & Substitute Parts

Part Overview

The MSART042SCG2R9AWRA01 is a 2.9 pF ceramic capacitor manufactured by Taiyo Yuden, rated for 25V operation with C0G/NP0 temperature coefficient characteristics. This surface-mount multilayer ceramic capacitor (MLCC) is packaged in 01005 (0402 Metric) form factor and is supplied in Tape & Reel (TR) packaging. The part is currently in Active product status with 953 pieces available in stock.

Equivalent and substitute parts become necessary when Tape & Reel packaging is unavailable, when alternative product series are required for design flexibility, or when inventory constraints necessitate sourcing from alternative manufacturing batches or series within the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the MSART042SCG2R9AWRA01 is permissible when the following parameters remain constant across all candidate parts:

• Capacitance Value: 2.9 pF (exact match required)
• Tolerance: ±0.05 pF (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)
• 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)

Variations in packaging format (Tape & Reel versus Cut Tape) and product series designation do not affect electrical or mechanical compatibility when all core parameters are identical. Product status differences (Active versus Not For New Designs) reflect manufacturing lifecycle positioning and do not alter functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The TMK042CG2R9AD-W is a direct electrical and mechanical equivalent to the MSART042SCG2R9AWRA01. Both parts are manufactured by Taiyo Yuden and satisfy identical electrical specifications, dimensional requirements, and compliance certifications.

Packaging Consideration: The primary difference between these parts is packaging format. The MSART042SCG2R9AWRA01 is supplied in Tape & Reel (TR) format, while the TMK042CG2R9AD-W is supplied in Cut Tape (CT) format. Selection between these formats depends on assembly line requirements and handling procedures.

Product Status Consideration: The MSART042SCG2R9AWRA01 maintains Active product status, indicating ongoing manufacturing support and suitability for new designs. The TMK042CG2R9AD-W carries Not For New Designs status, indicating this part is in mature or declining production phase. For new design implementations, the MSART042SCG2R9AWRA01 is the preferred selection. The TMK042CG2R9AD-W remains functionally equivalent for existing designs or applications where inventory availability is the primary constraint.

Compliance: Both parts are ROHS3 Compliant and carry identical ECCN (EAR99) and HTSUS (8532.24.0020) classifications, ensuring regulatory equivalence for procurement and export purposes.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG2R9AD-W be used as a direct replacement for MSART042SCG2R9AWRA01 in existing assemblies?

A: Yes. Both parts are electrically and mechanically identical. They share the same capacitance value (2.9 pF), tolerance (±0.05 pF), voltage rating (25V), temperature coefficient (C0G/NP0), operating temperature range (-55°C to 125°C), and physical dimensions (01005/0402 Metric package). The only difference is packaging format (Tape & Reel versus Cut Tape), which does not affect circuit performance.

Q: What is the significance of the "Not For New Designs" status on TMK042CG2R9AD-W?

A: This designation indicates the part is in a mature production phase and may have limited long-term availability. For new product designs, Taiyo Yuden recommends using the MSART042SCG2R9AWRA01, which carries Active status. However, TMK042CG2R9AD-W remains fully functional and compliant for existing designs or applications where immediate availability is required.

Q: Are there any differences in moisture sensitivity or handling requirements between these parts?

A: No. Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating they require no special moisture control during storage or handling. This classification applies equally to both the Tape & Reel and Cut Tape formats.

Q: Does packaging format affect circuit performance or reliability?

A: No. Tape & Reel and Cut Tape are alternative delivery formats for the same component. Once soldered onto a printed circuit board, the part performs identically regardless of its original packaging format. Packaging selection is determined by assembly line automation requirements and inventory management procedures.

Q: Are both parts suitable for high-reliability applications?

A: Both parts meet ROHS3 compliance and carry identical electrical specifications. Selection for high-reliability applications should be based on the Active product status of MSART042SCG2R9AWRA01, which ensures ongoing manufacturing support and quality assurance. TMK042CG2R9AD-W remains compliant but is in mature production phase.

Q: What is the inventory status for each part?

A: MSART042SCG2R9AWRA01 has 953 pieces in stock. TMK042CG2R9AD-W has 40,663 pieces in stock. Inventory levels should be verified at time of procurement, as availability is subject to change.
