Substitute Part Grouping Explanation

Substitution of the MLASH45MSB5155KTNA01 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 1.5 µF
• Tolerance: ±10%
• Rated voltage: 100V
• Temperature coefficient: X5R
• Operating temperature range: -55°C ~ 85°C

Mechanical Parameters:

• Package type: 1812 (4532 Metric)
• Physical dimensions: 0.177" L x 0.126" W (4.50mm x 3.20mm)
• Maximum thickness: 0.106" (2.70mm)
• Mounting type: Surface Mount, MLCC

Compliance Parameters:

• RoHS3 Compliance
• REACH Unaffected status
• Moisture Sensitivity Level 1

The substitute part HMK432BJ155KM-T meets all electrical, mechanical, and compliance requirements for direct substitution. Both parts are manufactured by Taiyo Yuden and share identical capacitance, voltage rating, temperature coefficient, package dimensions, and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: MLASH45MSB5155KTNA01

The MLASH45MSB5155KTNA01 is the recommended selection for new designs. This part carries Active product status from Taiyo Yuden, indicating ongoing manufacturing support and long-term availability. It is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for medical and non-critical applications.

Substitute Part: HMK432BJ155KM-T

The HMK432BJ155KM-T is electrically and mechanically equivalent to the primary part and is suitable for substitution when the MLASH45MSB5155KTNA01 is unavailable. However, this part carries a "Not For New Designs" product status, indicating that Taiyo Yuden has discontinued active development and support for this component. The HMK432BJ155KM-T should be used only for replacement, repair, or continuation of existing designs where supply of the primary part is constrained.

Both parts maintain identical compliance certifications (ROHS3, REACH Unaffected) and are suitable for the same applications. Selection between these parts should be based on availability and design phase requirements.

Frequently Asked Questions (FAQ)

Q: Can HMK432BJ155KM-T be used as a direct replacement for MLASH45MSB5155KTNA01?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical capacitance (1.5 µF), voltage rating (100V), temperature coefficient (X5R), operating temperature range (-55°C ~ 85°C), package type (1812/4532 Metric), physical dimensions, and compliance certifications. Direct substitution is permissible from a technical standpoint.

Q: What is the difference between these two parts?

A: The primary difference is product status. The MLASH45MSB5155KTNA01 is Active, while the HMK432BJ155KM-T is marked "Not For New Designs." This indicates that the HMK432BJ155KM-T has reached end-of-life in Taiyo Yuden's product portfolio. All electrical and mechanical specifications are identical.

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: Do both parts meet the same regulatory requirements?

A: Yes. Both the MLASH45MSB5155KTNA01 and HMK432BJ155KM-T are ROHS3 compliant and REACH unaffected. Moisture Sensitivity Level is 1 (Unlimited) for both parts, indicating no special handling requirements during storage or assembly.

Q: Which part should I specify for a new design?

A: Specify the MLASH45MSB5155KTNA01 for new designs. This part has Active product status and ensures long-term availability and manufacturing support from Taiyo Yuden.

Q: Can I use HMK432BJ155KM-T in a new design?

A: While technically equivalent, the HMK432BJ155KM-T carries "Not For New Designs" status. Using this part in new designs introduces supply risk and may complicate future production. The MLASH45MSB5155KTNA01 is the appropriate choice for new development.
