Key Parameters

Substitute Part Grouping Explanation

Substitution of the TMF212B7474MGHT is determined by strict equivalence across the following parameters:

Electrical Parameters:

• Capacitance value: 0.47 µF
• Tolerance: ±20%
• Voltage rating: 25V
• Temperature coefficient: X7R
• Operating temperature range: -55°C ~ 125°C

Mechanical Parameters:

• Package type: 0805 (2012 Metric)
• Mounting type: Surface Mount, MLCC
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Maximum thickness: 0.053" (1.35mm)

Compliance & Certification:

• RoHS3 compliance
• AEC-Q200 automotive qualification
• Moisture Sensitivity Level 1

The substitute part MAAST21GSB7474MTNA01 meets all these criteria and is therefore classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

The MAAST21GSB7474MTNA01 is a direct parametric equivalent to the TMF212B7474MGHT. Both parts are manufactured by Taiyo Yuden and share identical electrical, mechanical, and compliance specifications. The key distinction is product status: the original TMF212B7474MGHT is designated "Not For New Designs," while the MAAST21GSB7474MTNA01 maintains "Active" status in the manufacturer's current product portfolio.

For applications currently using TMF212B7474MGHT, the MAAST21GSB7474MTNA01 provides continued sourcing capability without design modification. Both parts satisfy AEC-Q200 automotive qualification requirements and ROHS3 compliance mandates. The substitute part is suitable for direct replacement in existing designs and is the appropriate selection for new designs requiring this capacitance, voltage, and package specification.

Frequently Asked Questions (FAQ)

Q: Can MAAST21GSB7474MTNA01 be used as a direct replacement for TMF212B7474MGHT?

A: Yes. Both parts are parametrically equivalent across all electrical specifications (0.47 µF, ±20%, 25V, X7R), mechanical dimensions (0805 package, 2.00mm x 1.25mm), and compliance certifications (AEC-Q200, ROHS3). No circuit modifications or PCB layout changes are required.

Q: What is the difference between these two part numbers?

A: The parts differ in manufacturer product series (M series versus MAAS series) and product status. The TMF212B7474MGHT is classified "Not For New Designs," while MAAST21GSB7474MTNA01 is actively produced. Functionally and electrically, they are identical.
