Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBAST31LAB7475MTNA01 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 4.7 µF
• Tolerance: ±20%
• Voltage rating: 25V
• Temperature coefficient: X7R
• Operating temperature range: -55°C to 125°C

Mechanical Parameters:

• Package type: 1206 (3216 Metric)
• Mounting type: Surface Mount, MLCC
• Physical dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm)
• Maximum thickness: 0.071" (1.80mm)
• Packaging format: Tape & Reel (TR)

Compliance Parameters:

• RoHS3 Compliance
• Moisture Sensitivity Level 1

All substitute parts listed maintain identical specifications across these parameters, ensuring direct interchangeability in circuit design and PCB assembly without modification to component placement, soldering profiles, or electrical circuit behavior.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: MSAST31LAB7475MTNA01

The MSAST31LAB7475MTNA01 from Taiyo Yuden is the preferred parametric equivalent. This part maintains active product status, ensuring continued availability and manufacturing support. It shares identical electrical and mechanical specifications with the MBAST31LAB7475MTNA01 and carries 3,047 pieces in current inventory.

Secondary Recommendations: C1206C475M3RAC7800 and CM316X7R475M25AT

Both the KEMET C1206C475M3RAC7800 and KYOCERA AVX CM316X7R475M25AT are active products with full parametric equivalence. The KEMET part offers the highest inventory availability at 16,650 pieces. Both manufacturers provide ROHS3 compliance and MSL 1 rating.

Alternative Consideration: C3216X7R1E475M160AC

The TDK Corporation C3216X7R1E475M160AC is a parametric equivalent with extensive inventory (48,650 pieces). However, this part carries "Not For New Designs" status. Selection of this part is appropriate only for legacy system maintenance or when existing design documentation specifies TDK components.

Not Recommended for New Designs: TMF316AB7475MLHT

The Taiyo Yuden TMF316AB7475MLHT is marked "Not For New Designs" and should not be selected for new circuit development. This part is suitable only for replacement in existing systems where it was originally specified.

Frequently Asked Questions (FAQ)

Q: Can MSAST31LAB7475MTNA01 be used as a direct replacement for MBAST31LAB7475MTNA01?

A: Yes. Both parts are manufactured by Taiyo Yuden and share identical electrical specifications (4.7 µF, 25V, X7R), mechanical dimensions (1206 package), and compliance ratings (ROHS3, MSL 1). No circuit modifications or PCB layout changes are required.

Q: What is the difference between the MBAST31 and MSAST31 series?

A: Both series are Taiyo Yuden 4.7 µF, 25V, X7R ceramic capacitors in 1206 package. The MSAST31 series is the current active product line, while MBAST31 represents an earlier generation. Electrical and mechanical performance are equivalent.

Q: Why is the C3216X7R1E475M160AC marked "Not For New Designs"?

A: This TDK part carries legacy status, indicating that TDK has transitioned this product to end-of-life management. While the part remains available and functionally equivalent, new designs should specify active products such as MSAST31LAB7475MTNA01, C1206C475M3RAC7800, or CM316X7R475M25AT.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All substitute parts use the 1206 (3216 Metric) package with identical physical dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm) and maximum thickness of 0.071" (1.80mm). PCB footprints and assembly processes require no modification.

Q: What is the significance of X7R temperature coefficient?

A: X7R indicates a temperature coefficient of ±15% across the operating range of -55°C to 125°C. This specification is maintained across all substitute parts, ensuring stable capacitance performance across the full temperature range.

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

A: Yes. All listed substitute parts meet identical electrical and mechanical specifications. Mixing manufacturers within a single design is permissible from an engineering standpoint, though procurement and supply chain considerations may influence this decision.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All substitute parts carry this rating, eliminating moisture-related reliability concerns.

Q: Is RoHS3 compliance maintained across all substitutes?

A: Yes. All substitute parts listed are RoHS3 compliant, meeting current environmental and hazardous substance restrictions for electronic components.
