Engineering Selection Recommendations

Primary Part Selection (MSASH31LSB7473MTNA01): The MSASH31LSB7473MTNA01 is the recommended choice for new designs requiring a general purpose 0.047 µF 100V X7R ceramic capacitor in 1206 package. This part maintains Active product status and is available in production quantities. It satisfies ROHS3 compliance and MSL 1 requirements for standard industrial applications.

Substitute Part Selection (HMK316B7473MLHT): The HMK316B7473MLHT serves as a direct electrical and mechanical equivalent with the addition of AEC-Q200 automotive qualification. This part is designated as Not For New Designs, indicating it is maintained for legacy system support and replacement applications. Selection of this substitute is appropriate when:

• Existing designs require component replacement with automotive-grade reliability
• Applications demand AEC-Q200 certification for automotive or mission-critical environments
• Inventory of the primary part is unavailable and automotive-qualified equivalents are acceptable

Both parts are manufactured by Taiyo Yuden and provide identical electrical performance, physical footprint, and environmental compliance characteristics.

Frequently Asked Questions (FAQ)

Q: Can HMK316B7473MLHT be used as a direct replacement for MSASH31LSB7473MTNA01 in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters including capacitance, voltage rating, temperature coefficient, package dimensions, and compliance certifications. Direct substitution is supported without circuit modification.

Q: What is the significance of the "Not For New Designs" status on the HMK316B7473MLHT?

A: This designation indicates the part is maintained in production for legacy system support and field replacements only. New designs should prioritize the MSASH31LSB7473MTNA01, which carries Active product status. However, the HMK316B7473MLHT remains fully functional and available for existing applications.

Q: Does the AEC-Q200 rating on HMK316B7473MLHT provide additional performance benefits?

A: AEC-Q200 is an automotive qualification standard that certifies enhanced reliability through rigorous testing protocols. For general purpose applications, this certification is not required. For automotive or high-reliability applications, the AEC-Q200 rating on HMK316B7473MLHT provides documented compliance with automotive industry standards.

Q: Are the physical dimensions identical between both parts?

A: Yes. Both parts are packaged in 1206 (3216 Metric) format with identical 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 interchangeable.

Q: What applications are supported by these capacitors?

A: The MSASH31LSB7473MTNA01 is specified for general purpose applications. The HMK316B7473MLHT extends support to automotive and SMPS filtering applications. Both parts function identically in their respective application domains due to matching electrical specifications.

Q: Is moisture sensitivity a concern for these parts?

A: No. Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special desiccant or controlled environment requirements.
