MLASH45MSB5225KTNA01 Equivalent & Substitute Parts

Part Overview

The MLASH45MSB5225KTNA01 is a 2.2 µF ceramic capacitor rated at 100V with X5R temperature coefficient, manufactured by Taiyo Yuden in 1812 (4532 Metric) surface mount package. This multilayer ceramic capacitor (MLCC) is designed for applications requiring stable capacitance across a wide temperature range and is currently in Active product status with 994 units in stock.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or when design flexibility allows for functionally equivalent alternatives from the same manufacturer. The HMK432BJ225KM-T represents a parametrically equivalent option, though it carries a Not For New Designs status and should be evaluated based on specific application requirements and design phase.

Substitute Part Grouping Explanation

Substitution eligibility for the MLASH45MSB5225KTNA01 is determined by strict parametric matching across the following critical criteria:

Mandatory Matching Parameters:

• Capacitance value: 2.2 µF
• Voltage rating: 100V
• Temperature coefficient: X5R
• Package designation: 1812 (4532 Metric)
• Tolerance: ±10%
• Operating temperature range: -55°C ~ 85°C
• Mounting type: Surface Mount, MLCC
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

The HMK432BJ225KM-T meets all mandatory matching parameters and is therefore classified as a parametric equivalent. Both parts are manufactured by Taiyo Yuden and share identical electrical and mechanical specifications. The primary distinction lies in product lifecycle status: MLASH45MSB5225KTNA01 is Active, while HMK432BJ225KM-T is designated Not For New Designs.

Engineering Selection Recommendations

For Active Design Programs: The MLASH45MSB5225KTNA01 is the recommended selection for new designs. It carries Active product status, ensuring long-term availability and manufacturer support. With 994 units currently in stock, supply continuity is established. This part meets all regulatory requirements including ROHS3 compliance and REACH unaffected status.

For Legacy or Existing Designs: The HMK432BJ225KM-T is electrically and mechanically equivalent and may be used as a substitute in existing designs where component replacement or rework is necessary. However, this part is designated Not For New Designs, indicating it is in end-of-life phase. The higher inventory level (1842 units) may provide short-term availability for legacy applications. Both parts share identical compliance certifications (ROHS3 Compliant, REACH Unaffected, EAR99 ECCN classification).

Compliance Considerations: Both parts are ROHS3 compliant and REACH unaffected, making them suitable for applications with regulatory compliance requirements. The identical HTSUS classification (8532.24.0020) confirms tariff and trade compliance alignment.

Frequently Asked Questions (FAQ)

Q: Can HMK432BJ225KM-T be used as a direct replacement for MLASH45MSB5225KTNA01 in existing assemblies?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications. They share identical capacitance (2.2 µF), voltage rating (100V), temperature coefficient (X5R), package dimensions (1812/4532 Metric), and operating temperature range (-55°C ~ 85°C). PCB footprints and assembly processes are compatible.

Q: Why does HMK432BJ225KM-T have a "Not For New Designs" status?

A: This designation indicates the part is in end-of-life phase and the manufacturer is not recommending it for new product development. However, it remains functionally equivalent and available for legacy applications or design revisions where substitution is necessary.

Q: Are there any differences in reliability or performance between these two parts?

A: No performance differences exist based on provided specifications. Both parts are manufactured by Taiyo Yuden with identical electrical characteristics, temperature stability (X5R), tolerance (±10%), and environmental ratings. Both carry MSL 1 (Unlimited) moisture sensitivity classification.

Q: What is the significance of the 1812 (4532 Metric) package designation?

A: This is the physical package size for surface mount multilayer ceramic capacitors. The 1812 designation refers to imperial dimensions (0.177" L x 0.126" W), while 4532 Metric refers to the equivalent metric dimensions (4.50mm x 3.20mm). Both parts use this identical package, ensuring PCB footprint compatibility and assembly equipment compatibility.

Q: Are both parts suitable for medical applications?

A: The MLASH45MSB5225KTNA01 is specified for Medical and Non-Critical applications. The HMK432BJ225KM-T is specified for SMPS Filtering applications. Application suitability should be determined based on specific circuit requirements and regulatory standards applicable to the end product.

Q: What is the difference in inventory availability?

A: MLASH45MSB5225KTNA01 has 994 units in stock, while HMK432BJ225KM-T has 1842 units available. For new designs, the higher inventory of the substitute should not influence selection; the Active status of MLASH45MSB5225KTNA01 ensures continued availability.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. They share the identical HTSUS tariff classification (8532.24.0020), confirming regulatory alignment.
