Substitute Part Grouping Explanation

Substitution of the TMF107B7473KAHT is determined by strict equivalence across the following parameters: capacitance value (0.047 µF), tolerance (±10%), voltage rating (25V), temperature coefficient (X7R), operating temperature range (-55°C ~ 125°C), package type (0603/1608 Metric), mounting method (Surface Mount MLCC), physical dimensions (0.063" L x 0.031" W, 0.035" max thickness), moisture sensitivity level (MSL 1), and compliance certifications (ROHS3, AEC-Q200).

All substitute parts listed maintain identical electrical specifications and mechanical compatibility. Variations in product status (Active vs. Not For New Designs vs. Obsolete), packaging format (Tape & Reel vs. Cut Tape), and optional features (Soft Termination, Open Mode) do not affect functional substitutability but may influence procurement strategy and long-term availability.

A: Yes. Both parts share identical electrical specifications (0.047 µF, ±10%, 25V, X7R), operating temperature range (-55°C ~ 125°C), package type (0603/1608 Metric), physical dimensions, MSL rating (1), and AEC-Q200 certification. MAAST168SB7473KTNA01 is an Active product from Taiyo Yuden and is suitable for new designs.

Q: What is the difference between MCAST168SB7473KTNA01 and MAAST168SB7473KTNA01?

A: Both parts are functionally equivalent with identical electrical and mechanical parameters. The difference lies in the series designation (MCAS vs. MAAS) within Taiyo Yuden's product portfolio. Both are Active products with equivalent inventory availability and performance characteristics.

Q: Why would I choose CL10B473KA8WPNC over other substitutes?

A: CL10B473KA8WPNC (Samsung Electro-Mechanics) maintains the highest inventory level (20,922 units) among all substitutes and is classified as Active. It features Open Mode failure characteristic and is suitable for applications requiring immediate availability and long-term supply assurance.

Q: Are Soft Termination variants compatible with standard PCB designs?

A: Yes. MCJCT168BB7473KTPA01 and GCJ188R71E473KA01D with Soft Termination are fully compatible with standard PCB designs. Soft Termination provides additional mechanical stress relief and is particularly beneficial for flexible PCB applications or designs subject to thermal cycling stress.

Q: Can I use CGJ3E2X7R1E473K080AA in automated assembly?

A: CGJ3E2X7R1E473K080AA is supplied in Cut Tape (CT) format rather than Tape & Reel (TR). This packaging format is not compatible with standard automated pick-and-place equipment. Manual handling or specialized tape feeding equipment is required. For automated assembly, select from the Tape & Reel alternatives.

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

A: Parts marked "Not For New Designs" (TMF107B7473KAHT and GCM188R71E473KA37D) indicate that the manufacturer has superseded these products with newer alternatives. While these parts remain functional and available, they should not be specified in new product designs. Use Active alternatives for new development.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All listed substitute parts carry AEC-Q200 automotive qualification, matching the original TMF107B7473KAHT specification. This certification is maintained across all manufacturers (Taiyo Yuden, YAGEO, TDK Corporation, Samsung Electro-Mechanics, and Murata Electronics).

Q: Do all substitutes have the same moisture sensitivity level?

A: Yes. All substitute parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Storage and handling requirements are identical to the original part.
