Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MLASU31LAB7475MTNA01 are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Capacitance: 4.7 µF
• Tolerance: ±20%
• Voltage Rating: 50V
• Temperature Coefficient: X7R
• Operating Temperature Range: -55°C ~ 125°C

Mechanical Parameters (Must Match):

• Package / Case: 1206 (3216 Metric)
• Size / Dimension: 0.126" L x 0.063" W (3.20mm x 1.60mm)
• Thickness (Max): 0.071" (1.80mm)
• Mounting Type: Surface Mount, MLCC

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

All substitute parts listed meet these criteria and are therefore electrically and mechanically interchangeable with the main part number.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: The MLASU31LAB7475MTNA01 (Taiyo Yuden, Active status) and C1206C475M5RACAUTO (KEMET, Active status) are recommended for new design implementations. Both parts maintain Active product status, ensuring long-term availability and manufacturing support. The C1206C475M5RACAUTO includes AEC-Q200 automotive qualification, providing additional reliability assurance for demanding applications.

For Existing Designs or Inventory Constraints: The C1206C475M5RAC7800 (KEMET, Active status) provides an alternative from an established manufacturer with higher current inventory (15,659 pieces). This part is functionally equivalent and maintains Active product status, though it is supplied in Cut Tape (CT) & Digi-Reel® packaging rather than standard Tape & Reel.

Legacy or Obsolescence Mitigation: The UMK316AB7475ML-T (Taiyo Yuden) and C3216X7R1H475M160AC (TDK Corporation) are marked as "Not For New Designs" but remain electrically and mechanically equivalent. These parts are suitable for replacement or repair of existing assemblies where design changes are not feasible. The C3216X7R1H475M160AC features Low ESL characteristics, which may provide performance benefits in specific filtering applications.

All substitute parts are ROHS3 Compliant, REACH Unaffected, and maintain MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage processes.

Frequently Asked Questions (FAQ)

Q: Can MLASU31LAB7475MTNA01 be directly replaced with any of the listed substitute parts?

A: Yes. All listed substitute parts are electrically and mechanically equivalent. They share identical capacitance (4.7 µF), tolerance (±20%), voltage rating (50V), temperature coefficient (X7R), operating temperature range (-55°C ~ 125°C), package dimensions (1206/3216 Metric), and compliance certifications (ROHS3, REACH Unaffected, MSL 1). Direct substitution is supported at the component level.

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

A: "Active" status indicates the manufacturer continues production and supports the part for new design implementations. "Not For New Designs" indicates the part is in mature or declining production phase; while still available, it is not recommended for new product development. For new designs, select MLASU31LAB7475MTNA01 or C1206C475M5RACAUTO, both marked Active.

Q: Are there packaging differences between substitute parts?

A: Yes. MLASU31LAB7475MTNA01, UMK316AB7475ML-T, C1206C475M5RACAUTO, and C3216X7R1H475M160AC are supplied in Tape & Reel (TR) packaging. C1206C475M5RAC7800 is supplied in Cut Tape (CT) & Digi-Reel® packaging. Both packaging formats are suitable for automated assembly; however, reel specifications and handling procedures may differ. Verify packaging compatibility with your assembly equipment before procurement.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity limitations. The part does not require special moisture-controlled storage, desiccant packaging, or bake-out procedures prior to soldering. Standard storage conditions are acceptable.

Q: Which substitute part is recommended for automotive applications?

A: C1206C475M5RACAUTO (KEMET) is qualified to AEC-Q200 automotive standards and is designated for automotive, bypass, and decoupling applications. This part is suitable for automotive-grade designs requiring enhanced reliability assurance.

Q: Can I use C1206C475M5RAC7800 in place of MLASU31LAB7475MTNA01 for medical applications?

A: C1206C475M5RAC7800 is specified for bypass and decoupling applications in commercial environments. The original MLASU31LAB7475MTNA01 is designated for medical and non-critical applications. While electrically equivalent, application-specific certifications or design qualifications for medical use should be verified with the respective manufacturers before substitution in regulated medical device designs.

Q: What is the significance of "Low ESL" noted for C3216X7R1H475M160AC?

A: Low ESL (Equivalent Series Inductance) indicates reduced parasitic inductance in the component design, which improves high-frequency filtering performance and reduces impedance at elevated frequencies. This characteristic may provide performance advantages in SMPS filtering or high-frequency decoupling applications, though all parts meet the same electrical specifications at rated conditions.
