Frequently Asked Questions (FAQ)

Q: Can I substitute MBASU31LAB5475KTNA01 with any of the listed parts?

A: Substitution is valid only when all electrical and mechanical parameters match exactly. All listed parts maintain identical capacitance (4.7 µF), tolerance (±10%), voltage rating (50V), temperature coefficient (X5R), operating temperature range (-55°C ~ 85°C), package form factor (1206/3216 Metric), physical dimensions, and compliance certifications. Direct pin-for-pin and footprint compatibility is confirmed.

Q: What is the difference between Active and Not For New Designs status?

A: Active status indicates the part is currently in production and recommended for new circuit designs. Not For New Designs status indicates the part is in mature or declining production phase and should be used only for legacy system maintenance, repair, or replacement applications. For new designs, prioritize Active status parts.

Q: Are there packaging differences between substitute parts?

A: Packaging format differs between some substitutes. MBASU31LAB5475KTNA01, UMK316ABJ475KL8T, C3216X5R1H475K160AB, and CL31A475KBHNNNE are supplied in Tape & Reel (TR) format. C1206C475K5PAC7800 and CC1206KKX5R9BB475 are supplied in Cut Tape (CT) & Digi-Reel® format. Verify packaging compatibility with your procurement and assembly processes.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All parts listed, including the main part MBASU31LAB5475KTNA01, have MSL 1 (Unlimited) rating. This indicates unlimited shelf life under normal storage conditions without baking requirements prior to assembly.

Q: Which substitute part has the lowest inventory risk?

A: C1206C475K5PAC7800 (KEMET) has the highest inventory availability at 237,314 pcs with Active product status, providing the lowest supply risk for ongoing production requirements.

Q: Is the TDK part C3216X5R1H475K160AB suitable for new designs?

A: No. C3216X5R1H475K160AB carries Not For New Designs status and should be reserved for legacy system support. For new designs, select from Active status alternatives: C1206C475K5PAC7800, CC1206KKX5R9BB475, CL31A475KBHNNNE, or KGM31AR51H475KU.

Q: What does X5R temperature coefficient mean?

A: X5R is a temperature coefficient classification for ceramic capacitors indicating capacitance variation of ±15% across the operating temperature range of -55°C to +85°C. This specification is identical across all listed parts.

Q: Can I use these parts interchangeably in my PCB assembly?

A: Yes, provided your PCB footprint is designed for 1206 (3216 Metric) package form factor. All substitute parts maintain identical physical dimensions (0.126" L x 0.063" W x 0.071" Max Thickness) and surface mount mounting type, enabling direct footprint compatibility.
