Substitute Part Grouping Explanation

Substitution eligibility for the MSART042SCG9R1BWRA01 is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Capacitance: 9.1 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 or Exceed):

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

The identified substitute part TMK042CG9R1BD-W meets all electrical and mechanical requirements. The primary difference is packaging format: the main part is supplied in Tape & Reel (TR) format, while the substitute is available in Cut Tape (CT) format. Both formats are compatible with automated assembly processes, with selection dependent on manufacturing workflow requirements.

Parameter Comparison

Engineering Selection Recommendations

For Active Production Programs: The MSART042SCG9R1BWRA01 is the recommended selection for new designs and ongoing production. This part maintains Active product status, ensuring long-term availability and supply chain stability. The Tape & Reel packaging format is optimized for high-volume automated assembly processes.

For Legacy Support or Supply Constraints: The TMK042CG9R1BD-W substitute is electrically and mechanically equivalent and provides an alternative source when the primary part experiences supply limitations. However, this part carries "Not For New Designs" status, indicating it is in the later stages of its product lifecycle. The Cut Tape packaging format is suitable for lower-volume production runs or manual assembly operations.

Packaging Format Considerations: Selection between Tape & Reel and Cut Tape formats depends on manufacturing process requirements. Tape & Reel format is standard for pick-and-place equipment in high-volume production. Cut Tape format is appropriate for lower-volume applications or when feeder compatibility differs.

Compliance Verification: Both parts are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating, indicating no special storage or handling requirements beyond standard component practices.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG9R1BD-W be used as a direct replacement for MSART042SCG9R1BWRA01?

A: Yes, from an electrical and mechanical standpoint. Both parts have identical capacitance (9.1 pF), tolerance (±0.1pF), voltage rating (25V), temperature coefficient (C0G/NP0), operating temperature range (-55°C ~ 125°C), package type (01005/0402 Metric), and physical dimensions. The primary difference is packaging format: Tape & Reel versus Cut Tape. Manufacturing process compatibility must be evaluated based on your assembly equipment specifications.

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

A: Tape & Reel packaging supplies components on a continuous carrier tape wound on a reel, optimized for automated pick-and-place equipment in high-volume production. Cut Tape packaging supplies components on tape segments, typically used for lower-volume runs or when feeder compatibility with specific equipment is required. Both formats contain the same component; the difference is in supply format and handling.

Q: Why is TMK042CG9R1BD-W marked "Not For New Designs"?

A: This designation indicates the part is in the later stages of its product lifecycle. While the part remains available and functional, Taiyo Yuden recommends using MSART042SCG9R1BWRA01 for new design implementations to ensure extended availability and supply continuity. The substitute should be reserved for legacy product support or temporary supply solutions.

Q: Are there any differences in reliability or performance between these parts?

A: No. Both parts are manufactured by Taiyo Yuden using identical specifications for capacitance, tolerance, voltage rating, temperature coefficient, and operating temperature range. Reliability characteristics are equivalent. The only functional difference is packaging format.

Q: Do both parts require the same storage and handling procedures?

A: Yes. Both parts carry Moisture Sensitivity Level 1 (Unlimited), meaning they have no special moisture sensitivity requirements. Standard component storage practices apply to both parts.

Q: Can I mix Tape & Reel and Cut Tape formats in the same production run?

A: This depends on your assembly equipment configuration. If your pick-and-place system supports both feeder types, mixing is possible. However, this typically requires separate feeder setup and may impact production efficiency. Consult your equipment documentation and manufacturing process specifications.

Q: What is the significance of the C0G/NP0 temperature coefficient?

A: C0G (also designated NP0) indicates a temperature coefficient of 0 ppm/°C, meaning capacitance remains stable across the operating temperature range of -55°C to 125°C. This is critical for precision applications where capacitance drift could affect circuit performance. Both parts provide identical temperature stability.

Q: Are both parts RoHS compliant?

A: Yes. Both MSART042SCG9R1BWRA01 and TMK042CG9R1BD-W are ROHS3 compliant, meeting current regulatory requirements for restricted substances in electronic components.
