Engineering Selection Recommendations

Primary Selection: MMASA31LAB7226KTNA01

The MMASA31LAB7226KTNA01 is the recommended selection for new designs. This part maintains active production status, ensuring long-term availability and supply chain stability. It is specified for medical and non-critical applications and carries ROHS3 compliance with unlimited moisture sensitivity rating.

Substitute Selection: AMK316AB7226KLHT

The AMK316AB7226KLHT provides electrical and mechanical equivalence to the primary part. However, this part carries a "Not For New Designs" status, indicating it is in end-of-life phase. The substitute is qualified to AEC-Q200 automotive standards and is specified for automotive and SMPS filtering applications. Use of this substitute is appropriate only for legacy system maintenance, repair, or replacement scenarios where the primary part is unavailable and the application requirements align with automotive qualification levels.

Both parts are manufactured by Taiyo Yuden and maintain identical electrical performance, package dimensions, and compliance certifications. Selection between these parts should be based on product lifecycle requirements and application qualification needs rather than electrical performance.

Frequently Asked Questions (FAQ)

Q: Can AMK316AB7226KLHT be used as a direct replacement for MMASA31LAB7226KTNA01 in new designs?

A: No. While the parts are electrically and mechanically equivalent, the AMK316AB7226KLHT carries a "Not For New Designs" status. New designs should specify the MMASA31LAB7226KTNA01, which is in active production.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts are packaged in 1206 (3216 Metric) with dimensions of 0.126" L x 0.063" W (3.20mm x 1.60mm) and maximum thickness of 0.071" (1.80mm). They are footprint-compatible for PCB assembly.

Q: What is the difference in application qualification between these parts?

A: The MMASA31LAB7226KTNA01 is specified for medical and non-critical applications. The AMK316AB7226KLHT is qualified to AEC-Q200 automotive standards and specified for automotive and SMPS filtering applications. Application qualification does not affect electrical performance but indicates the testing and reliability standards to which each part has been validated.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both parts carry Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life without moisture bake-out requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both the MMASA31LAB7226KTNA01 and AMK316AB7226KLHT are ROHS3 compliant.

Q: What is the inventory status for each part?

A: The MMASA31LAB7226KTNA01 has 912 units in stock. The AMK316AB7226KLHT has 1164 units in stock. Inventory levels are subject to change based on current demand and supply conditions.

Q: Can these parts be used interchangeably in existing production?

A: Electrical and mechanical interchangeability is confirmed. However, design documentation and bill of materials should be updated to reflect any part substitution. The "Not For New Designs" status of the AMK316AB7226KLHT should be considered in long-term supply planning.
