Engineering Selection Recommendations

Primary Selection (MSART042SCG5R1BWRA01): The MSART042SCG5R1BWRA01 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.

Substitute Selection (TMK042CG5R1BD-W): The TMK042CG5R1BD-W provides complete electrical and mechanical equivalence with identical capacitance, voltage rating, temperature coefficient, and package specifications. This part is designated as Not For New Designs but remains available for legacy system support and replacement applications. The Cut Tape packaging format is suitable for lower-volume or manual assembly operations.

Substitute Selection (TVS042CG5R1BC-W): The TVS042CG5R1BC-W offers full parametric equivalence to the primary part with identical electrical specifications and mechanical dimensions. This part is designated as Not For New Designs and is specified for RF, Microwave, and High Frequency applications. The Cut Tape packaging format and high inventory availability (78,439 pieces) make this part suitable for immediate replacement requirements in existing systems.

All three parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard surface mount assembly processes and environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG5R1BD-W be used as a direct replacement for MSART042SCG5R1BWRA01?

A: Yes. The TMK042CG5R1BD-W is a direct electrical and mechanical equivalent. Both parts have identical capacitance (5.1 pF), tolerance (±0.1pF), voltage rating (25V), temperature coefficient (C0G/NP0), and package dimensions (01005/0402 Metric). The only difference is the packaging format: Tape & Reel versus Cut Tape. Both formats are compatible with standard surface mount assembly equipment.

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

A: Tape & Reel packaging supplies components on a continuous reel suitable for automated high-speed pick-and-place assembly. Cut Tape packaging supplies components on individual tape segments, typically used for lower-volume production or manual assembly operations. Both formats contain the same component and are compatible with standard PCB assembly processes.

Q: Why are TMK042CG5R1BD-W and TVS042CG5R1BC-W marked as "Not For New Designs"?

A: The "Not For New Designs" designation indicates that these parts are legacy products no longer recommended for new product development. However, they remain available for replacement and support of existing systems. For new designs, MSART042SCG5R1BWRA01 (Active status) is the recommended selection.

Q: Are all three parts ROHS3 compliant?

A: Yes. MSART042SCG5R1BWRA01, TMK042CG5R1BD-W, and TVS042CG5R1BC-W are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and regulatory requirements.

Q: Can I use TVS042CG5R1BC-W in general purpose applications?

A: Yes. While TVS042CG5R1BC-W is specified for RF, Microwave, and High Frequency applications, it is electrically and mechanically identical to the general purpose MSART042SCG5R1BWRA01. The part can be used in any application requiring a 5.1 pF, 25V, C0G/NP0 ceramic capacitor in 01005 package.

Q: What is the operating temperature range for all substitute parts?

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

Q: Are there any inventory considerations when selecting a substitute?

A: Current inventory levels differ among the three parts. MSART042SCG5R1BWRA01 has 806 pieces in stock, TMK042CG5R1BD-W has 813 pieces, and TVS042CG5R1BC-W has 78,439 pieces available. Inventory availability may influence selection for immediate delivery requirements.
