Key Parameters

Substitute Part Grouping Explanation

Substitution of the TMF325B7474MNHT is permissible only with components that maintain identical electrical and mechanical parameters across all critical specifications. The substitution logic is based on the following key parameters:

Electrical Parameters (Non-Negotiable):

• Capacitance: 0.47 µF (exact match required)
• Voltage Rating: 25V (exact match required)
• Tolerance: ±20% (exact match required)
• Temperature Coefficient: X7R (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

Mechanical Parameters (Non-Negotiable):

• Package / Case: 1210 (3225 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Compliance Parameters (Non-Negotiable):

• RoHS Status: ROHS3 Compliant (exact match required)
• Automotive Rating: AEC-Q200 (exact match required)

The MAAST32NSB7474MTNA01 meets all specified criteria and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The MAAST32NSB7474MTNA01 is the qualified parametric equivalent substitute for the TMF325B7474MNHT. Selection between these parts should be based on the following engineering criteria:

For New Designs: The MAAST32NSB7474MTNA01 is the appropriate choice. This part carries Active product status, indicating ongoing manufacturer support and availability. It maintains full compliance with ROHS3 and AEC-Q200 automotive qualification standards.

For Legacy System Support and Continued Sourcing: Either part is electrically and mechanically interchangeable. The TMF325B7474MNHT remains available in inventory (470,193 pcs) despite Not For New Designs status. The MAAST32NSB7474MTNA01 offers reduced inventory (778 pcs) but provides assurance of long-term availability through active product status.

Compliance Considerations: Both parts satisfy automotive and environmental regulatory requirements. ROHS3 compliance and AEC-Q200 qualification are maintained across both options. REACH status is documented as Unaffected for the MAAST32NSB7474MTNA01.

Packaging and Assembly: Both parts are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes. Mechanical dimensions and mounting characteristics are identical, permitting direct substitution without PCB redesign or assembly process modification.

Frequently Asked Questions (FAQ)

Q: Can the MAAST32NSB7474MTNA01 be used as a direct replacement for the TMF325B7474MNHT in existing designs?

A: Yes. The MAAST32NSB7474MTNA01 is a parametric equivalent with identical electrical specifications (0.47 µF, 25V, ±20%, X7R), mechanical dimensions (1210 package, 3.20mm x 2.50mm x 2.10mm), and compliance certifications (ROHS3, AEC-Q200). Direct substitution is permissible without circuit modification or PCB redesign.

Q: What is the significance of the "Not For New Designs" status on the TMF325B7474MNHT?

A: This designation indicates the manufacturer has superseded this part number in their product line. New designs should incorporate the MAAST32NSB7474MTNA01, which carries Active product status. Existing designs using the TMF325B7474MNHT may continue operation without modification.

Q: Are there any differences in moisture sensitivity or handling requirements between these parts?

A: No. Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating identical handling and storage requirements. No special moisture control measures are required for either component.

Q: Do both parts meet automotive qualification standards?

A: Yes. Both the TMF325B7474MNHT and MAAST32NSB7474MTNA01 carry AEC-Q200 qualification, confirming suitability for automotive applications across the specified operating temperature range of -55°C to 125°C.

Q: What are the key parameters that must match for substitution to be valid?

A: Substitution requires exact matching of capacitance (0.47 µF), voltage rating (25V), tolerance (±20%), temperature coefficient (X7R), package type (1210), operating temperature range (-55°C ~ 125°C), mounting type (Surface Mount, MLCC), moisture sensitivity level (1), and compliance standards (ROHS3, AEC-Q200).

Q: Can a capacitor with a higher voltage rating be substituted?

A: Substitution is based on the parameters explicitly provided. The specified voltage rating is 25V. Substitution with components rated at different voltages is outside the scope of this equivalency reference.

Q: Is the MAAST32NSB7474MTNA01 available in the same packaging format?

A: Yes. Both parts are supplied in Tape & Reel (TR) packaging, suitable for automated pick-and-place assembly. Reel specifications and tape formatting are standard for 1210 package components.
