Engineering Selection Recommendations

MAASE31LAB7475MTNA01 (Primary Selection)

The MAASE31LAB7475MTNA01 is the recommended selection for new designs. This part carries Active product status, indicating full manufacturer support, ongoing production, and long-term availability. It is actively stocked with 1015 units in inventory and maintains all required automotive certifications including AEC-Q200 compliance.

EMF316AB7475MLHT (Substitute Selection)

The EMF316AB7475MLHT is a parametric equivalent suitable for existing designs or applications where inventory constraints on the primary part necessitate substitution. This part is designated as Not For New Designs, indicating it remains available for legacy applications but is not recommended for new product development. The part maintains identical electrical specifications, mechanical compatibility, and compliance certifications. Current inventory of 2729 units is available.

Selection between these parts should be based on design phase and supply requirements. Active designs should utilize MAASE31LAB7475MTNA01. Existing production or legacy applications may utilize EMF316AB7475MLHT without functional or compliance impact.

Frequently Asked Questions (FAQ)

Q: Can EMF316AB7475MLHT be used as a direct replacement for MAASE31LAB7475MTNA01 in existing assemblies?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. They share the same capacitance (4.7 µF), voltage rating (16V), temperature coefficient (X7R), package dimensions (1206/3216 Metric), and compliance certifications (AEC-Q200, RoHS3, MSL 1). Direct substitution is valid for existing production.

Q: Why is EMF316AB7475MLHT marked as Not For New Designs?

A: The Not For New Designs designation indicates the part is in a mature or declining production phase. While fully functional and compliant, Taiyo Yuden recommends new product development utilize the MAASE31LAB7475MTNA01, which carries Active status and guaranteed long-term availability.

Q: Are there any dimensional differences between these parts?

A: No. Both parts conform to identical 1206 (3216 Metric) package specifications with dimensions of 0.126" L x 0.063" W (3.20mm x 1.60mm) and maximum thickness of 0.071" (1.80mm). PCB footprints and assembly processes are identical.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both MAASE31LAB7475MTNA01 and EMF316AB7475MLHT carry AEC-Q200 certification, confirming suitability for automotive applications. Both are RoHS3 compliant and carry MSL 1 moisture sensitivity rating.

Q: What is the tolerance specification for these capacitors?

A: Both parts are specified at ±20% tolerance on the 4.7 µF capacitance value. This tolerance applies across the full operating temperature range of -55°C to 125°C.

Q: Can these parts be used interchangeably in SMPS filtering applications?

A: Yes. The EMF316AB7475MLHT specification explicitly lists SMPS Filtering as an application. The MAASE31LAB7475MTNA01, with identical electrical characteristics and X7R temperature stability, is equally suitable for SMPS filtering circuits.
