Key Parameters

Substitute Part Grouping Explanation

Substitution of the MMASG31LAB7475MTNA01 is determined by strict equivalence across the following parameters:

Critical Substitution Parameters:

• Capacitance: 4.7 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: 35V (exact match required)
• Temperature Coefficient: X7R (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Package / Case: 1206 (3216 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Physical Dimensions: 0.126" L x 0.063" W / 3.20mm x 1.60mm (exact match required)
• Thickness: 0.071" (1.80mm) maximum (exact match required)

All identified substitute parts meet these critical parameters. Variations in manufacturer, series designation, product status, and application focus do not affect electrical or mechanical compatibility when these core parameters are identical.

Engineering Selection Recommendations

MMASG31LAB7475MTNA01 (Primary Part - Active Status)

The MMASG31LAB7475MTNA01 maintains active product status and is the recommended selection for new designs. This part is actively manufactured and supported by Taiyo Yuden with 745 pieces currently in stock.

GMK316AB7475MLHT (Taiyo Yuden - Not For New Designs)

The GMK316AB7475MLHT is electrically and mechanically equivalent but carries "Not For New Designs" status. This part is suitable for legacy system support, replacement inventory, or applications where existing design validation has been completed. The GMK316AB7475MLHT includes AEC-Q200 automotive qualification and Ultra Low ESR features, making it applicable to automotive and SMPS filtering applications despite its discontinued design status.

C3216X7R1V475M160AB (TDK Corporation - Not For New Designs)

The C3216X7R1V475M160AB from TDK Corporation is a parametric equivalent with "Not For New Designs" status. This part features Low ESL characteristics and is designated for general purpose applications. With 5659 pieces in inventory, it provides alternative sourcing from a different manufacturer while maintaining full electrical and mechanical compatibility.

C3216X7R1V475M160AE (TDK Corporation - Not For New Designs)

The C3216X7R1V475M160AE is a parametric equivalent with "Not For New Designs" status. This part includes Soft Termination features and is designated for boardflex-sensitive applications. With 57631 pieces in inventory, this represents the highest available stock level among all equivalents and provides alternative sourcing with specialized termination characteristics.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical electrical specifications. Selection between active and discontinued parts depends on design phase requirements and application-specific needs.

Frequently Asked Questions (FAQ)

Q: Can the GMK316AB7475MLHT replace the MMASG31LAB7475MTNA01 in existing designs?

A: Yes. The GMK316AB7475MLHT is electrically and mechanically equivalent across all critical parameters: 4.7 µF capacitance, ±20% tolerance, 35V rating, X7R temperature coefficient, -55°C to 125°C operating range, and 1206 (3216 Metric) package. The "Not For New Designs" status does not affect compatibility in existing applications.

Q: What is the difference between the TDK C3216X7R1V475M160AB and C3216X7R1V475M160AE?

A: Both parts are parametrically equivalent with identical electrical and mechanical specifications. The primary difference is the termination type: C3216X7R1V475M160AB features Low ESL, while C3216X7R1V475M160AE features Soft Termination for boardflex-sensitive applications. Both are suitable for the same 1206 (3216 Metric) footprint and mounting requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts—MMASG31LAB7475MTNA01, GMK316AB7475MLHT, C3216X7R1V475M160AB, and C3216X7R1V475M160AE—are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.

Q: Can I use a substitute part with different voltage rating or capacitance?

A: No. Substitution requires exact equivalence in capacitance (4.7 µF), tolerance (±20%), voltage rating (35V), temperature coefficient (X7R), and operating temperature range (-55°C to 125°C). Parts with different electrical specifications are not interchangeable.

Q: Does package size remain identical across all substitute parts?

A: Yes. All substitute parts use the 1206 (3216 Metric) package with identical physical dimensions of 0.126" L x 0.063" W (3.20mm x 1.60mm) and maximum thickness of 0.071" (1.80mm). All are surface mount MLCCs with Tape & Reel packaging.

Q: Why is the MMASG31LAB7475MTNA01 recommended over discontinued parts?

A: The MMASG31LAB7475MTNA01 maintains active product status with ongoing manufacturer support and production. For new designs, active parts ensure long-term availability and supply chain stability. Discontinued parts ("Not For New Designs") are suitable for legacy system support or replacement inventory only.

Q: What inventory levels are available for each part?

A: Current inventory levels are: MMASG31LAB7475MTNA01 (745 Pcs), GMK316AB7475MLHT (1067 Pcs), C3216X7R1V475M160AB (5659 Pcs), and C3216X7R1V475M160AE (57631 Pcs). The C3216X7R1V475M160AE offers the highest stock availability.
