MSAST042SCGR75AWNA01 Equivalent & Substitute Parts

Part Overview

The MSAST042SCGR75AWNA01 is a 0.75 pF ceramic capacitor manufactured by Taiyo Yuden, rated for 25V operation with C0G/NP0 temperature coefficient characteristics. This surface-mount multilayer ceramic capacitor (MLCC) is packaged in 01005 (0402 Metric) form factor and is supplied in Tape & Reel (TR) packaging. The part maintains Active product status with full RoHS3 compliance and MSL 1 moisture sensitivity rating.

Substitute parts become necessary when primary inventory is unavailable, when alternative packaging formats are required for manufacturing processes, or when design flexibility permits selection from qualified equivalent components. The substitute identified maintains identical electrical specifications and mechanical dimensions while differing in packaging configuration and product lifecycle status.

Substitute Part Grouping Explanation

Substitution eligibility for the MSAST042SCGR75AWNA01 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance value: 0.75 pF
• Capacitance tolerance: ±0.05 pF
• Voltage rating: 25V
• Temperature coefficient: C0G, NP0
• Operating temperature range: -55°C to 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 Requirements:

• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)

The identified substitute part TMK042CGR75AD-W meets all electrical and mechanical equivalence criteria. The primary distinction is packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is supplied in Cut Tape (CT) format. Both formats are suitable for automated assembly processes with appropriate feeder equipment.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The MSAST042SCGR75AWNA01 is the recommended selection for new designs. This part carries Active product status, indicating ongoing manufacturer support, continued availability, and full qualification for production use. The Tape & Reel packaging format is optimized for high-volume automated assembly operations.

Substitute Part Selection: The TMK042CGR75AD-W is electrically and mechanically equivalent and is suitable for direct substitution in existing designs or when Cut Tape packaging is compatible with manufacturing processes. However, this part carries "Not For New Designs" status, indicating it is in the later stages of its product lifecycle. Use of this substitute should be limited to replacement, repair, or continuation of existing production runs where design changes are not feasible.

Compliance Considerations: Both parts maintain full RoHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution. Both parts carry identical ECCN (EAR99) and HTSUS (8532.24.0020) classifications for export and tariff purposes.

Packaging Compatibility: Verify that manufacturing equipment supports the selected packaging format. Tape & Reel (TR) format requires compatible reel feeders, while Cut Tape (CT) format requires compatible tape feeders or manual handling. Both formats are compatible with standard pick-and-place assembly equipment when appropriate feeder hardware is available.

Frequently Asked Questions (FAQ)

Q: Can TMK042CGR75AD-W be used as a direct replacement for MSAST042SCGR75AWNA01 in existing assemblies?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters: capacitance (0.75 pF ±0.05 pF), voltage rating (25V), temperature coefficient (C0G/NP0), operating temperature range (-55°C to 125°C), and physical dimensions (01005/0402 Metric package). The parts are functionally interchangeable at the circuit level.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging supplies components on a continuous reel of carrier tape, optimized for high-speed automated assembly. Cut Tape packaging supplies components on shorter tape segments, typically used for lower-volume production or manual assembly. Both formats use identical carrier tape specifications and component spacing. Equipment compatibility depends on feeder type available in the manufacturing facility.

Q: Why is TMK042CGR75AD-W marked "Not For New Designs"?

A: This designation indicates the part is in the mature or end-of-life phase of its product lifecycle. The manufacturer continues to support existing production runs but does not recommend this part for new product development. For new designs, MSAST042SCGR75AWNA01 (Active status) is the appropriate selection.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical RoHS3 compliance, MSL 1 moisture sensitivity rating, REACH Unaffected status, and identical ECCN and HTSUS classifications. Regulatory and compliance requirements are met equally by both parts.

Q: Can these parts be used interchangeably in high-frequency or RF applications?

A: Substitution eligibility is based strictly on the provided electrical and mechanical parameters. Application-specific performance characteristics such as frequency response, Q factor, or RF behavior are not included in the provided parameter set and cannot be evaluated for equivalence.

Q: What inventory considerations apply to these parts?

A: MSAST042SCGR75AWNA01 has 910 pieces in stock (Active status). TMK042CGR75AD-W has 1,097 pieces in stock (Not For New Designs status). Inventory availability may vary. Verify current stock levels with the supplier before committing to production schedules.
