MSART042SCG9R9BWRA01 Equivalent & Substitute Parts

Part Overview

The MSART042SCG9R9BWRA01 is a 9.9 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 maintains an Active product status and is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Substitute parts become necessary when the primary part experiences supply constraints, inventory limitations, or when design requirements permit alternative packaging formats or product lifecycle stages. The substitute identified maintains identical electrical specifications and mechanical compatibility while offering different packaging or availability characteristics.

Substitute Part Grouping Explanation

Substitution eligibility for the MSART042SCG9R9BWRA01 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance value: 9.9 pF
• Tolerance: ±0.1pF
• Voltage rating: 25V
• Temperature coefficient: C0G/NP0

Mechanical Equivalence Requirements:

• 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 Requirements:

• RoHS3 compliance
• MSL rating: 1 (Unlimited)

The substitute part TMK042CG9R9BD-W meets all electrical and mechanical equivalence criteria. The primary distinction is packaging format: the main part is supplied in Tape & Reel (TR) format, while the substitute is supplied in Cut Tape (CT) format. Both formats are compatible with automated assembly processes and represent alternative supply chain options.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (MSART042SCG9R9BWRA01): The MSART042SCG9R9BWRA01 is the recommended selection for new designs. This part carries Active product status, indicating ongoing manufacturer support and long-term availability. The Tape & Reel packaging format is optimized for high-volume automated assembly operations. ROHS3 compliance and MSL 1 rating ensure compatibility with modern manufacturing processes and storage requirements.

Substitute Part Selection (TMK042CG9R9BD-W): The TMK042CG9R9BD-W is electrically and mechanically equivalent and serves as a valid substitute when the primary part is unavailable. However, this part carries "Not For New Designs" status, indicating it is in the later stages of its product lifecycle. This part is suitable for:

• Replacement or repair of existing assemblies
• Low-volume production runs where inventory availability is the limiting factor
• Applications where design freeze permits use of legacy components

The Cut Tape packaging format is compatible with manual assembly and lower-volume pick-and-place operations but may require different feeder configurations compared to Tape & Reel format.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG9R9BD-W be used as a direct replacement for MSART042SCG9R9BWRA01 in new product designs?

A: TMK042CG9R9BD-W meets all electrical and mechanical specifications for direct substitution. However, the "Not For New Designs" status indicates this part is not recommended for new designs. Use MSART042SCG9R9BWRA01 for new designs to ensure long-term availability and manufacturer support.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging supplies components on a continuous reel suitable for high-speed automated assembly. Cut Tape packaging supplies components on tape segments, typically used for lower-volume production or manual assembly. Both formats contain identical components with identical electrical and mechanical properties.

Q: Are there any assembly process differences between these two parts?

A: Both parts use identical 01005 (0402 Metric) package dimensions and surface mount technology. Assembly process compatibility depends on equipment feeder configuration. Tape & Reel format requires reel feeders, while Cut Tape format requires tape feeders or manual placement. The components themselves are functionally identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both MSART042SCG9R9BWRA01 and TMK042CG9R9BD-W are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Both parts meet identical environmental and regulatory requirements.

Q: What is the significance of the "Not For New Designs" status on TMK042CG9R9BD-W?

A: "Not For New Designs" indicates the manufacturer is not actively promoting this part for new applications and may discontinue it in the future. This status does not affect current functionality or compliance. It reflects product lifecycle management and availability planning considerations.

Q: Can these parts be used interchangeably in existing inventory?

A: Yes, from an electrical and mechanical standpoint. However, packaging format differences may require separate handling and feeder setup. Verify assembly equipment compatibility with Cut Tape format before substituting in production environments.
