Substitute Part Grouping Explanation

Substitution logic for the MSART042SCG2R5AWRA01 is based on strict electrical and mechanical parameter matching. The identified substitute part TMK042CG2R5AD-W qualifies as a direct equivalent because it maintains all critical specifications:

Electrical Parameters (Must Match):

  • Capacitance: 2.5 pF
  • Tolerance: ±0.05pF
  • Voltage Rating: 25V
  • Temperature Coefficient: C0G, NP0
  • Operating Temperature Range: -55°C ~ 125°C

Mechanical Parameters (Must Match):

  • Package / Case: 01005 (0402 Metric)
  • Physical Dimensions: 0.016" L x 0.008" W (0.40mm x 0.20mm)
  • Thickness: 0.009" (0.22mm)
  • Mounting Type: Surface Mount, MLCC

Compliance Parameters (Must Match):

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

The primary difference between the main part and substitute is packaging format: MSART042SCG2R5AWRA01 is supplied in Tape & Reel (TR) configuration, while TMK042CG2R5AD-W is supplied in Cut Tape (CT) configuration. Both packaging formats are compatible with standard surface-mount assembly equipment.

Engineering Selection Recommendations

Primary Part Selection: The MSART042SCG2R5AWRA01 is the recommended choice for new designs. This part maintains Active product status from Taiyo Yuden, ensuring long-term availability and manufacturing support. The Tape & Reel packaging format is optimized for high-volume automated assembly processes and provides superior component protection during storage and transport.

Substitute Part Selection: The TMK042CG2R5AD-W qualifies as a direct electrical and mechanical equivalent and may be selected when the primary part is unavailable. However, this part carries "Not For New Designs" status, indicating that Taiyo Yuden has designated it for legacy applications only. The Cut Tape packaging format is suitable for lower-volume production runs or manual assembly operations but requires different handling procedures compared to Tape & Reel format.

Compliance Considerations: Both parts maintain ROHS3 compliance and identical Moisture Sensitivity Level (MSL 1), ensuring regulatory compatibility and identical storage requirements. No additional qualification is required when transitioning between these parts from a compliance perspective.

Packaging Format Impact: The transition from Tape & Reel to Cut Tape packaging affects only the supply chain and assembly process, not the electrical or mechanical performance of the component. Assembly equipment must be configured appropriately for the selected packaging format.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG2R5AD-W be used as a direct replacement for MSART042SCG2R5AWRA01 in existing designs?

A: Yes. Both parts are electrically and mechanically identical, with matching capacitance (2.5 pF), tolerance (±0.05pF), voltage rating (25V), temperature coefficient (C0G/NP0), and physical dimensions (01005/0402 Metric). The only difference is packaging format (Cut Tape versus Tape & Reel), which does not affect circuit performance.

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

A: This designation indicates that Taiyo Yuden has classified TMK042CG2R5AD-W as a legacy component. While it remains functionally equivalent and available, new product designs should prioritize the MSART042SCG2R5AWRA01 (Active status) to ensure long-term supply chain stability and manufacturer support.

Q: Are there any storage or handling differences between Tape & Reel and Cut Tape packaging?

A: Both packaging formats carry identical Moisture Sensitivity Level (MSL 1 - Unlimited), meaning no special moisture control is required during storage. However, Cut Tape format requires different handling procedures during assembly compared to Tape & Reel format. Assembly equipment must be configured appropriately for each packaging type.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both MSART042SCG2R5AWRA01 and TMK042CG2R5AD-W are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8532.24.0020) classifications, ensuring regulatory compatibility in all applications.

Q: What parameters must remain identical for substitution to be valid?

A: Capacitance, tolerance, voltage rating, temperature coefficient, operating temperature range, package type, physical dimensions, mounting type, and compliance certifications must all match exactly. Any deviation in these parameters disqualifies a part as a direct substitute.

Q: Can the substitute part be used in high-volume production?

A: While TMK042CG2R5AD-W is electrically and mechanically suitable, its "Not For New Designs" status and Cut Tape packaging format make it less optimal for high-volume automated production. The MSART042SCG2R5AWRA01 with Tape & Reel packaging is the preferred choice for production environments.
