Substitute Part Grouping Explanation

Substitution eligibility for the MSART042SCG4R3BWRA01 is determined by strict electrical and mechanical parameter matching. All substitute parts must satisfy the following criteria:

Electrical Parameters (Non-negotiable):

• Capacitance value: 4.3 pF
• Tolerance: ±0.1pF
• Voltage rating: 25V minimum
• Temperature coefficient: C0G/NP0
• Operating temperature range: -55°C to 125°C

Mechanical Parameters (Non-negotiable):

• 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 Parameters (Required):

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

The primary variable among substitute parts is packaging format (Tape & Reel versus Cut Tape) and product status. Packaging format does not affect electrical or mechanical compatibility; it reflects supply chain and manufacturing handling differences only.

Engineering Selection Recommendations

Primary Selection (MSART042SCG4R3BWRA01): The main part is recommended for new designs and production applications. It carries Active product status, indicating ongoing manufacturer support and long-term availability. Tape & Reel packaging is standard for automated assembly processes and high-volume manufacturing. RoHS3 compliance and MSL 1 rating ensure regulatory conformance and simplified handling procedures.

Substitute Selection (TMK042CG4R3BD-W): The substitute part TMK042CG4R3BD-W is electrically and mechanically identical to the main part and is suitable for direct replacement in existing designs or legacy systems. However, this part carries "Not For New Designs" status, indicating the manufacturer has discontinued active development and support. This part should be selected only when:

• Replacing components in existing production runs
• Addressing immediate supply constraints for established products
• Maintaining compatibility with legacy designs already in field deployment

The Cut Tape packaging format of the substitute part is compatible with manual assembly and lower-volume production environments but requires different handling procedures compared to Tape & Reel format.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG4R3BD-W be used as a direct replacement for MSART042SCG4R3BWRA01 in new product designs?

A: No. While TMK042CG4R3BD-W is electrically and mechanically identical, it carries "Not For New Designs" status. New designs should use MSART042SCG4R3BWRA01, which has Active product status and manufacturer support.

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

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, suitable for automated pick-and-place assembly. Cut Tape packaging supplies components on cut segments of carrier tape, suitable for manual assembly or lower-volume production. Both formats contain identical components with no electrical or mechanical differences.

Q: Are the electrical specifications identical between the main part and substitute?

A: Yes. Both parts have identical capacitance (4.3 pF), tolerance (±0.1pF), voltage rating (25V), temperature coefficient (C0G/NP0), and operating temperature range (-55°C to 125°C). They are electrically interchangeable.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both MSART042SCG4R3BWRA01 and TMK042CG4R3BD-W are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). They meet identical regulatory and handling requirements.

Q: Can I use the substitute part if my PCB layout is already designed for the main part?

A: Yes. Both parts have identical physical dimensions (0.016" L x 0.008" W / 0.40mm x 0.20mm) and maximum thickness (0.009" / 0.22mm). They fit the same PCB footprint without modification.

Q: What should I consider when choosing between these two parts?

A: For new designs, select MSART042SCG4R3BWRA01 due to Active status and long-term availability. For existing product support or immediate supply needs, TMK042CG4R3BD-W is electrically and mechanically compatible. Consider your assembly process: Tape & Reel for automated lines, Cut Tape for manual or low-volume assembly.
