MSART042SCG7R9BWRA01 Equivalent & Substitute Parts

Part Overview

The MSART042SCG7R9BWRA01 is a 7.9 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 960 pieces available in stock.

Equivalent and substitute parts become necessary when primary part availability is limited, when alternative packaging formats are required for manufacturing processes, or when design revisions necessitate component sourcing from multiple suppliers while maintaining identical electrical performance.

Substitute Part Grouping Explanation

Substitution eligibility for the MSART042SCG7R9BWRA01 is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Capacitance: 7.9 pF
• Tolerance: ±0.1pF
• Voltage Rating: 25V
• Temperature Coefficient: C0G, NP0
• Operating Temperature Range: -55°C ~ 125°C

Mechanical Parameters (Must Match Exactly):

• Package / Case: 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 (Must Match Exactly):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The primary distinction between the main part and its substitute lies in packaging format. The MSART042SCG7R9BWRA01 is supplied in Tape & Reel (TR) format, while the substitute part TMK042CG7R9BD-W is supplied in Cut Tape (CT) format. Both formats are compatible with automated assembly equipment, with the selection dependent on manufacturing line requirements and inventory management practices.

Parameter Comparison

Engineering Selection Recommendations

For Active Design Programs: The MSART042SCG7R9BWRA01 is the recommended selection for new designs. This part maintains Active product status from Taiyo Yuden, ensuring long-term availability and continued manufacturing support. The Tape & Reel packaging format is optimized for high-volume automated assembly operations.

For Existing Designs or Alternative Sourcing: The TMK042CG7R9BD-W substitute part is electrically and mechanically equivalent and maintains full ROHS3 compliance and MSL 1 rating. However, this part carries a "Not For New Designs" status, indicating it is in the mature or end-of-life phase of its product lifecycle. The Cut Tape packaging format is suitable for lower-volume production runs or manual assembly processes. Selection of this substitute should be limited to situations where the main part is unavailable or where manufacturing processes specifically require Cut Tape format.

Compliance Verification: Both parts are ROHS3 compliant and carry identical MSL ratings, confirming compatibility with modern manufacturing standards and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG7R9BD-W be used as a direct replacement for MSART042SCG7R9BWRA01 in production?

A: Yes, from an electrical and mechanical standpoint. Both parts are identical in capacitance (7.9 pF), tolerance (±0.1pF), voltage rating (25V), temperature coefficient (C0G/NP0), and physical dimensions (01005/0402 Metric). The primary difference is packaging format: Tape & Reel versus Cut Tape. Compatibility depends on whether your assembly equipment can process Cut Tape format. Both parts are ROHS3 compliant with MSL 1 rating.

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

A: Tape & Reel (TR) packaging supplies components on a continuous reel of carrier tape, optimized for high-speed automated pick-and-place assembly. Cut Tape (CT) packaging supplies the same components on shorter tape segments, typically used for lower-volume production or manual assembly processes. Both formats contain identical components; the difference is in delivery and handling format.

Q: Why is TMK042CG7R9BD-W marked "Not For New Designs"?

A: This designation indicates the part is in a mature or declining phase of its product lifecycle. While the part remains available and fully functional, the manufacturer recommends using MSART042SCG7R9BWRA01 (Active status) for new design programs to ensure long-term supply continuity and manufacturing support.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts are manufactured by Taiyo Yuden and share identical electrical specifications: 7.9 pF capacitance with ±0.1pF tolerance, 25V rating, C0G/NP0 temperature coefficient, and -55°C to 125°C operating range.

Q: Can I mix these parts in the same production batch?

A: Electrically and mechanically, yes. However, mixing packaging formats (Tape & Reel and Cut Tape) in a single production run may create handling and inventory management complications. Standardizing on a single packaging format per production batch is recommended for operational efficiency.

Q: What compliance certifications apply to both parts?

A: Both MSART042SCG7R9BWRA01 and TMK042CG7R9BD-W are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage or handling.
