MSART042SCG1R7AWRA01 Equivalent & Substitute Parts

Part Overview

The MSART042SCG1R7AWRA01 is a 1.7 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 currently in Active product status. Substitute parts become necessary when the primary part experiences supply constraints, inventory limitations, or when design requirements permit alternative packaging formats while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the MSART042SCG1R7AWRA01 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part TMK042CG1R7AD-W maintains identical specifications for capacitance (1.7 pF), tolerance (±0.05pF), rated voltage (25V), temperature coefficient (C0G/NP0), operating temperature range (-55°C ~ 125°C), package type (01005/0402 Metric), physical dimensions, and mounting characteristics.

The primary distinction between the main part and its substitute is the packaging format: the MSART042SCG1R7AWRA01 is supplied in Tape & Reel (TR) configuration, while the TMK042CG1R7AD-W is supplied in Cut Tape (CT) format. Both formats contain identical components with no electrical or mechanical differences. Both parts maintain ROHS3 compliance and MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

The MSART042SCG1R7AWRA01 is the preferred selection for new designs due to its Active product status. This designation indicates ongoing manufacturer support, continued production, and long-term availability assurance.

The TMK042CG1R7AD-W is electrically and mechanically equivalent but carries a "Not For New Designs" status. This classification indicates the part is in mature or declining production phase. Selection of this substitute is appropriate only when the MSART042SCG1R7AWRA01 is unavailable and the application permits use of a legacy component. Both parts satisfy identical electrical requirements and maintain equivalent compliance certifications (ROHS3, MSL 1).

The packaging format difference (Tape & Reel versus Cut Tape) does not affect component performance or compatibility with standard surface mount assembly equipment. Selection between these formats depends on production volume requirements and inventory management practices rather than technical performance criteria.

Frequently Asked Questions (FAQ)

Q: Are the MSART042SCG1R7AWRA01 and TMK042CG1R7AD-W electrically identical?

A: Yes. Both parts have identical capacitance (1.7 pF), tolerance (±0.05pF), rated voltage (25V), temperature coefficient (C0G/NP0), and operating temperature range (-55°C ~ 125°C). They are direct electrical equivalents.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on a reel, suitable for high-volume automated assembly. Cut Tape (CT) packaging supplies components on cut segments of carrier tape, typically used for lower volumes or manual assembly. The components themselves are identical; only the delivery format differs.

Q: Can I use TMK042CG1R7AD-W in place of MSART042SCG1R7AWRA01 in new designs?

A: The TMK042CG1R7AD-W carries "Not For New Designs" status. While electrically and mechanically equivalent, this designation indicates limited future availability. New designs should specify the MSART042SCG1R7AWRA01 to ensure long-term supply continuity.

Q: Are both parts RoHS compliant?

A: Yes. Both the MSART042SCG1R7AWRA01 and TMK042CG1R7AD-W are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Do these parts require different handling or storage procedures?

A: No. Both parts have identical MSL 1 rating, indicating unlimited shelf life under normal storage conditions. Handling and storage procedures are identical.

Q: What is the physical footprint compatibility?

A: Both parts use the 01005 (0402 Metric) package with identical dimensions: 0.016" L x 0.008" W (0.40mm x 0.20mm) and maximum thickness of 0.009" (0.22mm). They are footprint-compatible with all 01005/0402 surface mount assembly equipment and PCB designs.
