Engineering Selection Recommendations

Primary Selection: MLASH45MSB7155KTNA01

The MLASH45MSB7155KTNA01 is the recommended selection for new designs. This part carries Active product status, indicating full manufacturer support, ongoing production, and availability for long-term supply chain planning. It is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for medical and non-critical applications.

Substitute Selection: HMK432B7155KM-T

The HMK432B7155KM-T is a parametric equivalent suitable for use when the primary part is unavailable. This part maintains identical electrical, mechanical, and compliance specifications. However, it carries "Not For New Designs" product status, indicating the manufacturer has discontinued active development and support for this variant. The HMK432B7155KM-T is appropriate for replacement, repair, or continuation of existing designs where supply of the primary part is constrained.

Both parts are manufactured by Taiyo Yuden and are ROHS3 compliant with MSL 1 rating, permitting unlimited shelf life storage without moisture sensitivity concerns.

Frequently Asked Questions (FAQ)

Q: Can HMK432B7155KM-T be used as a direct replacement for MLASH45MSB7155KTNA01?

A: Yes. All electrical parameters (capacitance, voltage rating, temperature coefficient, operating temperature range), mechanical parameters (package dimensions, thickness, mounting type), and compliance certifications (RoHS3, REACH, MSL) are identical. The parts are electrically and mechanically interchangeable at the component level.

Q: What is the difference between these two parts?

A: The primary difference is product status. MLASH45MSB7155KTNA01 is Active, while HMK432B7155KM-T is Not For New Designs. Both parts are manufactured by Taiyo Yuden and share identical specifications. The status difference reflects manufacturer support and production lifecycle, not electrical or mechanical capability.

Q: Are there any package or footprint differences?

A: No. Both parts use the 1812 (4532 Metric) surface mount package with identical dimensions of 0.177" L x 0.126" W (4.50mm x 3.20mm) and maximum thickness of 0.106" (2.70mm). PCB footprints and assembly processes are identical.

Q: Which part should be specified for new product designs?

A: MLASH45MSB7155KTNA01 should be specified for new designs due to its Active product status, ensuring manufacturer support and long-term availability. HMK432B7155KM-T is appropriate only for replacement or continuation of existing designs where supply constraints exist.

Q: Are both parts suitable for medical applications?

A: MLASH45MSB7155KTNA01 is specified for medical and non-critical applications. HMK432B7155KM-T is specified for SMPS filtering applications. Both parts are ROHS3 compliant and REACH unaffected. Application suitability should be confirmed against specific design requirements and regulatory standards.

Q: What is the moisture sensitivity rating for these capacitors?

A: Both parts have MSL 1 (Unlimited) rating, indicating no moisture sensitivity concerns. These parts do not require special moisture control during storage, handling, or assembly.
