MLASH32MSB5475KPCA01 Equivalent & Substitute Parts

Part Overview

The MLASH32MSB5475KPCA01 is a 4.7 µF ceramic capacitor rated at 100V with X5R temperature coefficient in 1210 (3225 Metric) surface mount package. This multilayer ceramic capacitor (MLCC) is manufactured by Taiyo Yuden and is currently in Active product status. The part is designed for medical and non-critical applications requiring stable capacitance across a wide operating temperature range of -55°C to 85°C.

Substitute parts become necessary when the primary part experiences extended lead times, inventory constraints, or when design flexibility permits selection from alternative qualified sources. The MLASH32MSB5475KPCA01 has one identified parametric equivalent that maintains identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MLASH32MSB5475KPCA01 is determined by strict equivalence across the following critical parameters:

Capacitance value must be 4.7 µF with ±10% tolerance. Voltage rating must be 100V or higher. Temperature coefficient must be X5R to ensure stable performance across the -55°C to 85°C operating range. Package and case designation must be 1210 (3225 Metric) to ensure mechanical and electrical compatibility with existing PCB layouts. Mounting type must be Surface Mount MLCC. Physical dimensions must match or be compatible with the specified footprint. RoHS3 compliance and MSL 1 rating are required for regulatory and environmental compatibility.

The identified substitute part HMK325BJ475KM-PE meets all these criteria and is therefore classified as a parametric equivalent.

Engineering Selection Recommendations

The MLASH32MSB5475KPCA01 is the recommended primary selection for new designs due to its Active product status. This designation indicates ongoing manufacturing support, quality assurance, and long-term availability from Taiyo Yuden.

The HMK325BJ475KM-PE substitute part is electrically and mechanically equivalent and maintains full compliance with ROHS3 and MSL 1 requirements. However, this part carries a "Not For New Designs" status, indicating that Taiyo Yuden has transitioned this product line. The HMK325BJ475KM-PE is suitable for legacy system support, field replacements, or applications where existing inventory is available and design changes are not feasible.

Both parts are manufactured by the same supplier and share identical electrical performance characteristics, package dimensions, and regulatory compliance certifications. Selection between these parts should be based on design phase (new versus legacy), inventory availability, and supply chain considerations rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can HMK325BJ475KM-PE be used as a direct replacement for MLASH32MSB5475KPCA01 in new designs?

A: HMK325BJ475KM-PE is electrically and mechanically equivalent and will function identically in the circuit. However, it carries "Not For New Designs" status. New designs should specify MLASH32MSB5475KPCA01 to ensure long-term supply continuity and manufacturer support.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts are packaged in 1210 (3225 Metric) case with dimensions of 3.20mm length, 2.50mm width, and 2.70mm maximum thickness. They are footprint-compatible and require no PCB layout modifications.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both MLASH32MSB5475KPCA01 and HMK325BJ475KM-PE are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level). They meet identical environmental and regulatory standards.

Q: What is the difference between these parts if all electrical and mechanical parameters are identical?

A: The primary difference is product lifecycle status. MLASH32MSB5475KPCA01 is in Active status with ongoing manufacturing support. HMK325BJ475KM-PE is in "Not For New Designs" status, indicating Taiyo Yuden has phased this product line. Both parts are functionally equivalent.

Q: Can these parts be interchanged in existing inventory or field replacements?

A: Yes. For legacy systems, field replacements, or applications where design changes are not feasible, HMK325BJ475KM-PE can be used interchangeably with MLASH32MSB5475KPCA01 without circuit modifications or performance degradation.

Q: What applications are these capacitors designed for?

A: MLASH32MSB5475KPCA01 is specified for medical and non-critical applications. HMK325BJ475KM-PE is specified for SMPS (Switched-Mode Power Supply) filtering. Both parts maintain identical electrical characteristics across their rated operating temperature range.
