MSAST042SCG080BWNA01 Equivalent & Substitute Parts

Part Overview

The MSAST042SCG080BWNA01 is an 8 pF ceramic capacitor manufactured by Taiyo Yuden, rated for 25V with C0G/NP0 temperature coefficient characteristics. This surface-mount multilayer ceramic capacitor (MLCC) is packaged in 01005 (0402 Metric) form factor and is classified as Active product status. Substitute parts become necessary when the primary part experiences supply constraints, inventory limitations, or when design requirements permit alternative packaging configurations while maintaining identical electrical performance.

Substitute Part Grouping Explanation

Substitution of the MSAST042SCG080BWNA01 is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 8 pF
• Capacitance tolerance: ±0.1pF
• Voltage rating: 25V (equal or higher)
• Temperature coefficient: C0G/NP0
• Operating temperature range: -55°C ~ 125°C

Mechanical Equivalence Criteria:

• 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 Criteria:

• RoHS3 compliance
• Moisture Sensitivity Level 1

The substitute part TMK042CG080BD-W meets all electrical and mechanical parameters. The primary distinction is packaging configuration: the main part is supplied in Tape & Reel (TR) format, while the substitute is supplied in Cut Tape (CT) format. Both formats are compatible with automated assembly processes and do not affect electrical performance or board-level functionality.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (MSAST042SCG080BWNA01): The MSAST042SCG080BWNA01 is designated as Active product status and is the preferred selection for new designs. This part carries full manufacturer support and is recommended for applications requiring long-term supply assurance and design continuity.

Substitute Part Selection (TMK042CG080BD-W): The TMK042CG080BD-W is classified as Not For New Designs. This designation indicates the part is available for existing inventory and legacy system support but should not be selected for new product development. The substitute is electrically and mechanically equivalent and may be used in applications where supply of the primary part is unavailable, provided that the design timeline does not require long-term manufacturer support.

Packaging Consideration: The difference between Tape & Reel (TR) and Cut Tape (CT) packaging affects supply chain logistics and automated assembly compatibility. Both formats are suitable for pick-and-place assembly operations. Cut Tape format may require manual handling or specialized feeder equipment depending on assembly line configuration.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG080BD-W be used as a direct replacement for MSAST042SCG080BWNA01 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The substitute meets all electrical specifications (8 pF, ±0.1pF, 25V, C0G/NP0) and physical requirements (01005 package, surface mount). The only difference is packaging format (Cut Tape versus Tape & Reel) and product status designation.

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

A: This designation indicates that TMK042CG080BD-W is in a mature or declining phase of its product lifecycle. While the part is currently available and fully functional, the manufacturer does not recommend its selection for new product development. For new designs, MSAST042SCG080BWNA01 (Active status) is the appropriate choice.

Q: Are there any assembly process differences between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging is optimized for high-volume automated assembly with continuous reel feeding. Cut Tape (CT) packaging is supplied in individual tape segments and may require manual loading or alternative feeder systems. Both formats are compatible with standard pick-and-place equipment, though feeder compatibility should be verified with your assembly partner.

Q: Do both parts meet the same compliance and regulatory requirements?

A: Yes. Both MSAST042SCG080BWNA01 and TMK042CG080BD-W are ROHS3 compliant, carry Moisture Sensitivity Level 1 (Unlimited), and share identical ECCN (EAR99) and HTSUS (8532.24.0020) classifications.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the identical temperature range of -55°C to 125°C, with C0G/NP0 temperature coefficient ensuring stable capacitance performance across this full range.

Q: Can the substitute part be used in high-reliability or military applications?

A: Substitution decisions for high-reliability or military applications must be based on specific program requirements and qualification standards. The electrical and mechanical equivalence of both parts is established; however, program-specific certifications, traceability requirements, and supplier qualification status should be evaluated independently.
