Substitute Part Grouping Explanation
Substitution validity for the MLASE31LSB7475KTNA01 is determined by strict equivalence across the following parameters:
Critical Parameters for Substitution:
- Capacitance: 4.7 µF (exact match required)
- Tolerance: ±10% (exact match required)
- Voltage - Rated: 16V (exact match required)
- Temperature Coefficient: X7R (exact match required)
- Operating Temperature Range: -55°C ~ 125°C (exact match required)
- Package / Case: 1206 (3216 Metric) (exact match required)
- Physical Dimensions: 0.126" L x 0.063" W, 0.071" max thickness (exact match required)
- Mounting Type: Surface Mount, MLCC (exact match required)
- RoHS Status: ROHS3 Compliant (exact match required)
- Moisture Sensitivity Level: 1 (Unlimited) (exact match required)
Secondary Considerations:
- Packaging format (Tape & Reel vs. Cut Tape & Digi-Reel) does not affect electrical or mechanical compatibility
- Product status (Active vs. Not For New Designs) indicates design lifecycle but does not prevent functional substitution
- Application classifications and ratings (AEC-Q200, automotive, medical) indicate qualification levels but do not restrict substitution when parameters match
All substitute parts listed maintain identical electrical performance and physical compatibility with the main part number.

Frequently Asked Questions (FAQ)
Q: Can I substitute the MLASE31LSB7475KTNA01 with any of the listed parts?
A: Yes, all listed parts are electrically and mechanically equivalent. They share identical capacitance (4.7 µF), tolerance (±10%), voltage rating (16V), temperature coefficient (X7R), operating temperature range (-55°C ~ 125°C), package type (1206), physical dimensions, and compliance ratings (ROHS3, MSL 1).
Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?
A: Both packaging formats contain identical components. Tape & Reel (TR) is supplied on continuous tape suitable for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® is supplied in shorter tape lengths or alternative reel formats. The choice depends on production volume and assembly equipment compatibility, not electrical performance.
Q: Why are some parts marked "Not For New Designs"?
A: Parts marked "Not For New Designs" indicate that the manufacturer has transitioned the product to end-of-life or obsolescence status. These parts remain functionally equivalent and suitable for replacement in existing designs but should not be selected for new product development. Active status parts are preferred for new designs.
Q: Does AEC-Q200 certification affect substitution compatibility?
A: AEC-Q200 certification indicates automotive-grade qualification and reliability testing. It does not affect electrical or mechanical compatibility. Parts with AEC-Q200 certification are suitable substitutes for non-certified parts in the same electrical specifications. However, non-certified parts should not be substituted into designs requiring AEC-Q200 qualification.
Q: Are all substitute parts RoHS3 compliant?
A: Yes, all listed substitute parts are ROHS3 compliant, matching the compliance status of the main part number MLASE31LSB7475KTNA01.
Q: What does MSL 1 (Unlimited) moisture sensitivity mean?
A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. This is the least restrictive moisture sensitivity level and simplifies supply chain management.
Q: Can I use these substitutes in medical applications?
A: The main part MLASE31LSB7475KTNA01 is specified for medical and non-critical applications. Substitute parts listed with general purpose or automotive classifications have not been explicitly qualified for medical applications. For medical device designs, verify that the selected substitute part carries appropriate medical device certifications or obtain manufacturer confirmation of medical application suitability.
Q: Which substitute part has the highest inventory availability?
A: CL31B475KOHNFNE (Samsung Electro-Mechanics) has the highest inventory availability at 176,193 pieces in stock.
Q: Are there any electrical performance differences between manufacturers?
A: All listed substitute parts share identical electrical specifications: 4.7 µF capacitance, ±10% tolerance, 16V voltage rating, and X7R temperature coefficient. Electrical performance is equivalent across all manufacturers. Differences exist only in product lifecycle status, packaging format, and application-specific certifications (such as AEC-Q200 for automotive).
