Substitute Part Grouping Explanation

Substitution of the MSART042SCG7R3BWRA01 is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Capacitance: 7.3 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):

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

The primary distinction between the main part and its substitute lies in packaging format. The MSART042SCG7R3BWRA01 is supplied in Tape & Reel (TR) format, while the substitute TMK042CG7R3BD-W is supplied in Cut Tape (CT) format. Both parts are manufactured by Taiyo Yuden and share identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The TMK042CG7R3BD-W serves as a parametric equivalent to the MSART042SCG7R3BWRA01 for applications requiring identical electrical and mechanical performance. Both parts meet ROHS3 compliance and share equivalent moisture sensitivity ratings.

Product Status Consideration: The MSART042SCG7R3BWRA01 maintains Active product status, indicating ongoing manufacturer support and availability. The substitute part TMK042CG7R3BD-W carries a "Not For New Designs" status, indicating it is in mature or legacy phase. For new design implementations, the MSART042SCG7R3BWRA01 in Tape & Reel packaging is the preferred selection.

Packaging Format Distinction: Selection between these parts depends on manufacturing equipment and procurement requirements. Tape & Reel (TR) packaging is standard for automated pick-and-place assembly operations. Cut Tape (CT) packaging is suitable for manual assembly, rework operations, or applications with lower volume requirements.

Both parts are manufactured by Taiyo Yuden and carry identical ECCN (EAR99) and HTSUS (8532.24.0020) classifications, confirming regulatory equivalence for export and trade purposes.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG7R3BD-W be used as a direct replacement for MSART042SCG7R3BWRA01 in production assembly?

A: Yes, from an electrical and mechanical standpoint. Both parts are identical in capacitance (7.3 pF), tolerance (±0.1pF), voltage rating (25V), temperature coefficient (C0G/NP0), and physical dimensions (01005/0402 Metric). The difference is packaging format: MSART042SCG7R3BWRA01 is Tape & Reel, while TMK042CG7R3BD-W is Cut Tape. Compatibility depends on your assembly equipment's ability to handle Cut Tape format.

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

A: Tape & Reel packaging supplies components on a continuous reel suitable for automated pick-and-place machines. Cut Tape packaging provides components on tape segments, typically used for manual assembly, rework, or lower-volume applications. Both formats contain the same component; the difference is in delivery and handling method.

Q: Are there any electrical performance differences between these two parts?

A: No. Both parts share identical electrical specifications: 7.3 pF capacitance, ±0.1pF tolerance, 25V rating, C0G/NP0 temperature coefficient, and -55°C to 125°C operating range. Performance in circuit applications is equivalent.

Q: Why is TMK042CG7R3BD-W marked "Not For New Designs"?

A: This designation indicates the part is in a mature or legacy phase of its product lifecycle. While it remains functionally equivalent and available, Taiyo Yuden recommends using the MSART042SCG7R3BWRA01 (Active status) for new design implementations to ensure long-term availability and support.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the MSART042SCG7R3BWRA01 and TMK042CG7R3BD-W are ROHS3 compliant, carry Moisture Sensitivity Level 1 (Unlimited), and share identical ECCN (EAR99) and HTSUS (8532.24.0020) classifications.

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

A: From a component performance perspective, yes. Both formats contain identical parts. However, mixing packaging formats in a single production run may require different handling procedures and equipment setup. Consult your assembly process documentation for packaging format compatibility with your specific equipment.

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

A: C0G (also designated NP0) indicates the capacitor has minimal capacitance change across the operating temperature range of -55°C to 125°C. This stability is critical for precision applications where capacitance drift must be minimized. Both substitute parts maintain this specification.
