Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MMASE31LAB7475MTNA01 are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Capacitance: 4.7 µF
• Tolerance: ±20%
• Voltage Rating: 16V
• Temperature Coefficient: X7R
• Operating Temperature Range: -55°C to 125°C

Mechanical Parameters (Must Match):

• Package / Case: 1206 (3216 Metric)
• Physical Dimensions: 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):

• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Status: ROHS3 Compliant
• Packaging: Tape & Reel (TR)

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

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status): The MMASE31LAB7475MTNA01 and C1206C475M4RAC7800 are both in Active product status. For new designs, C1206C475M4RAC7800 (KEMET) is the preferred parametric equivalent, offering identical electrical and mechanical specifications with higher inventory availability (4909 units).

Secondary Selection (Legacy Designs): EMF316AB7475MLHT (Taiyo Yuden) is designated as Not For New Designs but remains electrically and mechanically equivalent. This part is suitable for sustaining production of existing designs where component qualification has been completed.

Tertiary Selection (Legacy Designs): C3216X7R1C475M160AB and C3216X7R1C475M160AM (TDK Corporation) are both designated as Not For New Designs. These parts are suitable for legacy applications where design qualification has been established.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical operating temperature ranges (-55°C to 125°C), ensuring compatibility with the original part's environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can C1206C475M4RAC7800 be used as a direct replacement for MMASE31LAB7475MTNA01?

A: Yes. Both parts share identical electrical specifications (4.7 µF, ±20%, 16V, X7R), mechanical dimensions (1206 package, 3.20mm x 1.60mm), and compliance ratings (ROHS3, MSL 1). Direct substitution is supported without circuit modification.

Q: What is the difference between the Taiyo Yuden MMASE31LAB7475MTNA01 and EMF316AB7475MLHT?

A: Both parts are manufactured by Taiyo Yuden and share identical electrical and mechanical specifications. The primary difference is product status: MMASE31LAB7475MTNA01 is Active, while EMF316AB7475MLHT is Not For New Designs. EMF316AB7475MLHT is suitable for sustaining production of existing designs.

Q: Are TDK parts C3216X7R1C475M160AB and C3216X7R1C475M160AM interchangeable with the main part?

A: Yes. Both TDK parts meet all electrical and mechanical substitution criteria. However, both are designated as Not For New Designs. They are suitable for legacy applications where design qualification has been completed.

Q: What does "Not For New Designs" mean for substitute parts?

A: This designation indicates the manufacturer has discontinued or is phasing out the part for new applications. These parts remain electrically and mechanically equivalent and are suitable for sustaining production of existing designs where the part has been previously qualified.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 compliance certification, matching the main part's regulatory status.

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

A: Yes. All substitute parts are rated MSL 1 (Unlimited), identical to the main part. This allows storage without moisture-controlled conditions.

Q: Can substitute parts be mixed in the same production batch?

A: All substitute parts meet identical electrical, mechanical, and compliance specifications. However, component qualification procedures should be followed according to your organization's engineering standards before introducing a new manufacturer or part number into production.

Q: What is the significance of the 1206 (3216 Metric) package designation?

A: The 1206 package is the imperial designation; 3216 Metric is the metric equivalent. Both refer to the same physical dimensions (3.20mm x 1.60mm). All substitute parts use this identical package, ensuring PCB footprint compatibility.
