Engineering Selection Recommendations

Primary Part Selection: The MAASL31LAB7475KTNA01 is the recommended choice for new designs. This part maintains Active product status from Taiyo Yuden, ensuring long-term availability and continued manufacturing support. With 929 units in current inventory, supply continuity is established. Full AEC-Q200 qualification and ROHS3 compliance satisfy automotive and regulatory requirements.

Substitute Part Selection: The LMF316AB7475KLHT serves as a parametric equivalent for applications where the primary part becomes unavailable. This substitute maintains identical electrical performance, mechanical compatibility, and automotive qualification. However, the LMF316AB7475KLHT carries "Not For New Designs" status, restricting its use to legacy system support, field replacements, or inventory management scenarios. Both parts are manufactured by Taiyo Yuden and share identical compliance certifications.

Compliance Considerations: Both parts satisfy ROHS3 compliance and carry AEC-Q200 automotive qualification. Moisture Sensitivity Level 1 classification indicates unlimited shelf life without special storage requirements. ECCN classification as EAR99 and HTSUS code 8532.24.0020 apply uniformly across both parts.

Frequently Asked Questions (FAQ)

Q: Can LMF316AB7475KLHT be used as a direct replacement for MAASL31LAB7475KTNA01 in existing designs?

A: Yes. The LMF316AB7475KLHT is a parametric equivalent with identical capacitance (4.7 µF), voltage rating (10V), temperature coefficient (X7R), operating temperature range (-55°C ~ 125°C), and 1206 package dimensions. Both parts are AEC-Q200 qualified and ROHS3 compliant. Direct substitution is electrically and mechanically compatible.

Q: What is the difference in product status between these parts?

A: MAASL31LAB7475KTNA01 maintains Active status, indicating ongoing manufacturing and recommended use for new designs. LMF316AB7475KLHT is designated "Not For New Designs," meaning Taiyo Yuden no longer recommends this part for new product development but continues to support existing applications and field replacements.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 1206 (3216 Metric) package 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 MAASL31LAB7475KTNA01 and LMF316AB7475KLHT carry AEC-Q200 qualification, meeting automotive industry reliability and quality standards.

Q: What is the tolerance specification for these capacitors?

A: Both parts are specified at ±10% tolerance on the 4.7 µF capacitance value, resulting in an acceptable range of 4.23 µF to 5.17 µF.

Q: Are there any moisture sensitivity concerns?

A: No. Both parts are classified as Moisture Sensitivity Level 1, indicating unlimited shelf life without special moisture control or baking requirements prior to assembly.

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

A: Yes. The LMF316AB7475KLHT specification explicitly lists SMPS Filtering as an application. The MAASL31LAB7475KTNA01, while specified for automotive applications, shares identical electrical characteristics and is suitable for SMPS filtering use.
