MSASE31LSB7475KTNA01 Equivalent & Substitute Parts

Part Overview

The MSASE31LSB7475KTNA01 is a 4.7 µF ±10% 16V ceramic capacitor manufactured by Taiyo Yuden in the 1206 (3216 Metric) package with X7R temperature coefficient. This multilayer ceramic capacitor (MLCC) is designed for general-purpose applications and operates across the temperature range of -55°C to 125°C. The part is currently active in production and ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required, or when design specifications allow for functionally compatible alternatives from different manufacturers. This reference provides direct substitutes and parametric equivalents that maintain electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: What makes a part a valid substitute for the MSASE31LSB7475KTNA01?

A: A valid substitute must match all mandatory electrical and mechanical parameters: 4.7 µF capacitance, ±10% tolerance, 16V voltage rating, X7R temperature coefficient, -55°C to 125°C operating range, 1206 package, and identical physical dimensions. All substitutes listed maintain these specifications.

Q: Can I use a part marked "Not For New Designs" in a new product?

A: Parts marked "Not For New Designs" (EMF316AB7475KLHT and C3216X7R1C475K160AB) are suitable only for replacement or maintenance of existing assemblies. For new designs, select from active products.

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

A: Tape & Reel packaging is continuous reel format suitable for high-volume automated assembly. Cut Tape & Digi-Reel packaging provides smaller quantities in tape format or on alternative reels, suitable for lower-volume production or prototyping. Both formats contain identical components; the difference is in delivery and handling format only.

Q: Are automotive-qualified parts (AEC-Q200) required for all applications?

A: AEC-Q200 qualification is required only for automotive applications. For general-purpose, industrial, or consumer applications, parametric equivalents without automotive certification are suitable. Automotive-qualified parts provide enhanced reliability testing and documentation.

Q: Can I substitute a part with higher inventory availability?

A: Yes. Parts with higher inventory availability (such as CL31B475KOHNFNE with 176,193 pcs or C1206C475K4RAC7800 with 35,651 pcs) provide the same electrical and mechanical performance as the original part. Inventory levels do not affect functional compatibility.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 (Unlimited) indicates that the component has unlimited shelf life and does not require special moisture-controlled storage or handling. All listed substitutes share this specification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant, matching the environmental compliance status of the original MSASE31LSB7475KTNA01.

Q: Can I mix different manufacturers' parts in the same assembly?

A: Yes. All listed substitutes meet identical electrical and mechanical specifications. Mixing manufacturers in the same assembly is acceptable from a functional standpoint. However, verify that procurement, quality, and supply chain processes support multi-source components.

Q: What is the significance of the X7R temperature coefficient?

A: X7R temperature coefficient specifies that capacitance variation remains within ±15% across the full operating temperature range of -55°C to 125°C. This stability is critical for applications requiring consistent performance across temperature extremes. All substitutes maintain this specification.
