Substitute Part Grouping Explanation

Substitution of the MSART042SCG8R7BWRA01 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance value: 8.7 pF
• Capacitance tolerance: ±0.1pF
• Voltage rating: 25V
• Temperature coefficient: C0G, NP0
• Operating temperature range: -55°C ~ 125°C

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 Equivalence Requirements:

• RoHS3 compliance
• Moisture Sensitivity Level: 1 (Unlimited)

All substitute parts listed maintain full equivalence across these parameters. Variations in packaging format (Tape & Reel versus Cut Tape) and product lifecycle status do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status): The MSART042SCG8R7BWRA01 remains the recommended selection for new designs. This part maintains Active product status, ensuring long-term availability and manufacturer support. It is supplied in Tape & Reel packaging, which is standard for automated assembly processes.

Secondary Selection (Tape & Reel Packaging): The TVS042CG8R7BC-W provides an alternative with identical electrical and mechanical specifications. Although marked as Not For New Designs, this part is available in Tape & Reel packaging and maintains full parametric equivalence. This part is suitable for legacy system maintenance or when existing assembly line configurations require TR packaging.

Alternative Selection (Cut Tape Packaging): The TMK042CG8R7BD-W offers parametric equivalence with Cut Tape packaging. This format is applicable to manual assembly processes or low-volume production runs. Although marked as Not For New Designs, this part maintains full electrical and mechanical compatibility with the primary part number.

All three parts carry ROHS3 compliance and identical moisture sensitivity ratings, ensuring regulatory and environmental compatibility across substitution scenarios.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG8R7BD-W be used as a direct replacement for MSART042SCG8R7BWRA01 in automated assembly?

A: TMK042CG8R7BD-W is electrically and mechanically equivalent but is supplied in Cut Tape (CT) packaging rather than Tape & Reel (TR). Automated pick-and-place equipment typically requires Tape & Reel format. Cut Tape packaging is suitable for manual assembly or semi-automated processes with tape feeder compatibility.

Q: What is the significance of the "Not For New Designs" status on substitute parts?

A: This status indicates the manufacturer does not recommend these parts for new product development. However, they remain functionally equivalent and suitable for replacement in existing applications, legacy system support, or when supply of the Active part is constrained.

Q: Are all three parts interchangeable from an electrical performance standpoint?

A: Yes. All three parts share identical capacitance (8.7 pF), tolerance (±0.1pF), voltage rating (25V), temperature coefficient (C0G/NP0), and operating temperature range (-55°C ~ 125°C). Electrical performance is equivalent across all substitutes.

Q: Does packaging format affect the component's electrical characteristics?

A: No. Tape & Reel and Cut Tape are packaging and delivery formats only. They do not alter the electrical or mechanical properties of the ceramic capacitor itself.

Q: Are moisture sensitivity and RoHS compliance identical across all three parts?

A: Yes. All three parts carry Moisture Sensitivity Level 1 (Unlimited) and ROHS3 compliance, ensuring identical handling requirements and regulatory status.

Q: What inventory considerations should guide part selection?

A: The MSART042SCG8R7BWRA01 has 1107 pieces in stock. The TVS042CG8R7BC-W has 80935 pieces available, and the TMK042CG8R7BD-W has 40777 pieces. Higher inventory levels on substitute parts may provide supply chain advantages in constrained market conditions.
