• Temperature coefficient: X5R
• Operating temperature range: -55°C ~ 85°C
• Package format: 1210 (3225 Metric)
• Mounting type: Surface Mount, MLCC
• Physical dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm)
• Thickness: 0.106" (2.70mm) maximum
• Regulatory compliance: RoHS3 Compliant, REACH Unaffected

The substitute part HMK325BJ475KM-PE meets all mandatory parameters and is classified as a parametric equivalent. This part is manufactured by Taiyo Yuden under the M series designation and maintains identical electrical specifications and physical form factor compatibility with the primary part.

Parameter Comparison

Engineering Selection Recommendations

MSASH32MSB5475KPCA01 (Primary Part): The MSASH32MSB5475KPCA01 maintains Active product status, indicating ongoing manufacturer support and continued availability for new design implementations. This part is the preferred selection for new circuit designs and long-term production requirements. Current inventory of 1131 pieces supports immediate procurement needs.

HMK325BJ475KM-PE (Substitute Part): The HMK325BJ475KM-PE is classified as a parametric equivalent with identical electrical and mechanical specifications. However, this part carries a "Not For New Designs" product status designation. This substitute is suitable for legacy system maintenance, field replacements, and design revisions where component interchangeability is required. The significantly higher inventory level (62,565 pieces) provides supply availability for high-volume replacement scenarios. Both parts maintain identical RoHS3 compliance and REACH unaffected status, ensuring regulatory compatibility in all applications.

Selection between these parts should prioritize the Active-status primary part for new designs while reserving the substitute for situations where supply continuity or legacy support is the determining factor.

Frequently Asked Questions (FAQ)

Q: Can HMK325BJ475KM-PE be used as a direct replacement for MSASH32MSB5475KPCA01 in existing circuit designs?

A: Yes. The HMK325BJ475KM-PE is a parametric equivalent with identical capacitance (4.7 µF), voltage rating (100V), temperature coefficient (X5R), operating temperature range (-55°C ~ 85°C), and physical package dimensions (1210 / 3225 Metric). Both parts are surface mount MLCCs with matching electrical performance for SMPS filtering applications.

Q: What is the significance of the "Not For New Designs" status on HMK325BJ475KM-PE?

A: This designation indicates that while the part remains functionally equivalent and available, the manufacturer does not recommend its use in new circuit designs. The primary part MSASH32MSB5475KPCA01 with Active status is the preferred choice for new development. The substitute is appropriate for field replacements, legacy system support, and design revisions.

Q: Are there any physical compatibility concerns when substituting between these parts?

A: No. Both parts share identical package specifications: 1210 (3225 Metric) case format, 0.126" length x 0.098" width (3.20mm x 2.50mm), and 0.106" maximum thickness (2.70mm). PCB footprints and assembly processes are fully compatible.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both MSASH32MSB5475KPCA01 and HMK325BJ475KM-PE are RoHS3 compliant and REACH unaffected. Moisture sensitivity level is identical at MSL 1 (unlimited), requiring no special handling or storage precautions.

Q: What is the tolerance specification for these capacitors?

A: Both parts carry a ±10% capacitance tolerance. This tolerance applies to the 4.7 µF nominal value, resulting in an acceptable range of 4.23 µF to 5.17 µF at rated conditions.

Q: Are these parts suitable for high-temperature applications?

A: Both parts operate across the temperature range of -55°C to 85°C with X5R temperature coefficient characteristics. This range is standard for industrial and commercial SMPS filtering applications. The X5R coefficient ensures stable capacitance performance across this temperature span.
