MSASH45MSB7105KTNA01 Equivalent & Substitute Parts

Part Overview

The MSASH45MSB7105KTNA01 is a 1 µF, 100V ceramic capacitor manufactured by Taiyo Yuden in the 1812 (4532 Metric) package with X7R temperature coefficient. This surface mount multilayer ceramic capacitor (MLCC) is designed for general purpose applications and operates across the temperature range of -55°C to 125°C. The part maintains Active product status with 987 units currently in stock.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or when design requirements align with alternative qualified components that share identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MSASH45MSB7105KTNA01 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 1 µF
• Tolerance: ±10%
• Rated voltage: 100V
• Temperature coefficient: X7R
• Operating temperature range: -55°C to 125°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 configuration: Surface Mount, MLCC

Compliance Parameters:

• RoHS3 compliance
• Moisture Sensitivity Level 1

The substitute part HMK432B7105KMHT meets all electrical, mechanical, and compliance requirements for direct substitution. Differences in product status, series designation, and application focus do not affect functional interchangeability within the specified parameter constraints.

Engineering Selection Recommendations

Primary Selection: MSASH45MSB7105KTNA01

The MSASH45MSB7105KTNA01 maintains Active product status and is the preferred choice for new designs. This part carries full manufacturer support and is available in adequate inventory (987 units in stock). It is suitable for general purpose applications requiring a 1 µF, 100V ceramic capacitor in the 1812 package format.

Alternative Selection: HMK432B7105KMHT

The HMK432B7105KMHT is electrically and mechanically equivalent to the primary part and carries ROHS3 compliance with MSL 1 rating. However, this part is designated "Not For New Designs" by the manufacturer. Selection of this substitute is appropriate only when:

• The primary part is unavailable or subject to extended lead times
• Existing inventory of the substitute part is available (940 units in stock)
• Design modifications to accommodate the substitute are not feasible
• The application does not require ongoing manufacturer support for new production runs

Both parts are manufactured by Taiyo Yuden and share identical electrical performance, mechanical dimensions, and compliance certifications. The substitute part includes AEC-Q200 automotive qualification and is documented for SMPS filtering and automotive applications, though these designations do not alter its functional equivalence for general purpose use.

Frequently Asked Questions (FAQ)

Q: Can HMK432B7105KMHT be used as a direct replacement for MSASH45MSB7105KTNA01 in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters: 1 µF capacitance, ±10% tolerance, 100V rating, X7R temperature coefficient, -55°C to 125°C operating range, 1812 package dimensions, and ROHS3 compliance. Physical board layout and assembly processes require no modification.

Q: What is the significance of the "Not For New Designs" status on the HMK432B7105KMHT?

A: This designation indicates the manufacturer is not actively promoting this part for new product development and may discontinue it without advance notice. It remains suitable for replacement or repair of existing assemblies but should not be selected as the primary component for new designs where the MSASH45MSB7105KTNA01 is available.

Q: Are there differences in reliability or failure rates between these parts?

A: No reliability or failure rate data is provided in the component specifications for either part. Both parts carry identical moisture sensitivity (MSL 1) and RoHS3 compliance ratings. The HMK432B7105KMHT includes AEC-Q200 automotive qualification, which indicates automotive-grade reliability testing, though this does not establish superiority for general purpose applications.

Q: Do the package dimensions and mounting requirements differ between these parts?

A: No. Both parts are packaged in 1812 (4532 Metric) format with identical physical dimensions of 0.177" L x 0.126" W (4.50mm x 3.20mm) and maximum thickness of 0.106" (2.70mm). Both are surface mount MLCCs supplied in Tape & Reel packaging. No PCB layout or assembly process modifications are required for substitution.

Q: What is the difference between the MSAS and M series designations?

A: The MSAS series (MSASH45MSB7105KTNA01) and M series (HMK432B7105KMHT) represent different product lines within Taiyo Yuden's ceramic capacitor portfolio. Series designation does not affect electrical or mechanical equivalence when all other parameters are identical. The series difference reflects internal manufacturer classification and does not impact functional performance or interchangeability.

Q: Can these parts be used interchangeably in automotive applications?

A: The HMK432B7105KMHT carries AEC-Q200 automotive qualification. The MSASH45MSB7105KTNA01 is specified for general purpose applications without automotive qualification listed. For applications requiring automotive-grade components, the HMK432B7105KMHT is the appropriate selection. For non-automotive general purpose use, both parts are functionally equivalent.
