Key Parameters

Substitute Part Grouping Explanation

Substitution of the MMASU32MSB7475MPNA01 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

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

Mechanical Parameters:

• Package / Case: 1210 (3225 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Physical Dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm) (exact match required)
• Thickness (Max): 0.106" (2.70mm) (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All identified substitute parts meet these criteria. Differences in product status, series designation, and application focus do not affect electrical or mechanical compatibility.

Engineering Selection Recommendations

Primary Selection: MMASU32MSB7475MPNA01

The MMASU32MSB7475MPNA01 is the recommended choice for new designs. This part carries Active product status, indicating full manufacturer support and continued availability. It is suitable for medical and non-critical applications and maintains all required compliance certifications.

Secondary Selection: UMF325B7475MMHP

The UMF325B7475MMHP is electrically and mechanically equivalent to the primary part. However, this part carries Not For New Designs status, indicating the manufacturer is transitioning away from this product line. This part includes AEC-Q200 automotive qualification and is specified for automotive and SMPS filtering applications. Selection of this part is appropriate only when existing inventory must be utilized or when design requirements specifically call for automotive-qualified components.

Tertiary Selection: UMK325B7475MM-P

The UMK325B7475MM-P is electrically and mechanically equivalent to the primary part. This part also carries Not For New Designs status. It is specified for SMPS filtering applications. Selection of this part is appropriate only when existing inventory must be utilized or when design requirements specifically call for SMPS filtering-qualified components.

All three parts are ROHS3 compliant with MSL 1 (Unlimited) rating and are suitable for direct substitution based on electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can UMF325B7475MMHP be used as a direct replacement for MMASU32MSB7475MPNA01?

A: Yes. Both parts are electrically and mechanically identical with matching capacitance (4.7 µF), voltage rating (50V), temperature coefficient (X7R), operating temperature range (-55°C ~ 125°C), package type (1210 / 3225 Metric), and physical dimensions. Both are ROHS3 compliant with MSL 1 rating. The primary difference is product status; UMF325B7475MMHP is marked Not For New Designs.

Q: Can UMK325B7475MM-P be used as a direct replacement for MMASU32MSB7475MPNA01?

A: Yes. Both parts are electrically and mechanically identical with matching capacitance (4.7 µF), voltage rating (50V), temperature coefficient (X7R), operating temperature range (-55°C ~ 125°C), package type (1210 / 3225 Metric), and physical dimensions. Both are ROHS3 compliant with MSL 1 rating. The primary difference is product status; UMK325B7475MM-P is marked Not For New Designs.

Q: What are the critical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by exact equivalence in capacitance (4.7 µF), tolerance (±20%), voltage rating (50V), temperature coefficient (X7R), operating temperature range (-55°C ~ 125°C), package type (1210 / 3225 Metric), physical dimensions (0.126" L x 0.098" W / 3.20mm x 2.50mm), maximum thickness (0.106" / 2.70mm), RoHS compliance status (ROHS3), and moisture sensitivity level (MSL 1 / Unlimited).

Q: Are there any differences in physical footprint between these parts?

A: No. All three parts share identical package specifications: 1210 (3225 Metric) case, 0.126" L x 0.098" W (3.20mm x 2.50mm) dimensions, and 0.106" (2.70mm) maximum thickness. PCB layout and assembly processes require no modification when substituting between these parts.

Q: What is the significance of the Not For New Designs status on UMF325B7475MMHP and UMK325B7475MM-P?

A: Not For New Designs status indicates the manufacturer is discontinuing or has discontinued active development and promotion of these product lines. These parts remain available from existing inventory but are not recommended for incorporation into new product designs. For new designs, MMASU32MSB7475MPNA01 (Active status) is the appropriate selection.

Q: Are all three parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and regulatory requirements.
