MSASH45MSB5105KTNA01 Equivalent & Substitute Parts

Part Overview

The MSASH45MSB5105KTNA01 is a 1 µF, 100V ceramic capacitor manufactured by Taiyo Yuden in the X5R temperature coefficient classification with 1812 (4532 Metric) package dimensions. This multilayer ceramic capacitor (MLCC) is designed for surface mount applications, specifically for SMPS filtering circuits. The part is currently in Active product status with 811 pieces available in new original inventory.

Substitute parts become necessary when the primary part experiences supply constraints, inventory depletion, or when design flexibility permits the use of functionally equivalent alternatives that meet identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the MSASH45MSB5105KTNA01 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must match the following criteria:

Electrical Parameters:

• Capacitance: 1 µF
• Tolerance: ±10%
• Voltage Rating: 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 & Packaging:

• Packaging Format: Tape & Reel (TR)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Parts meeting all these parameters are considered direct functional equivalents and may be substituted without circuit redesign or board layout modification.

Engineering Selection Recommendations

Primary Part: MSASH45MSB5105KTNA01

The MSASH45MSB5105KTNA01 is the recommended selection for new designs. This part carries Active product status, indicating ongoing manufacturer support, continued availability, and compliance with current industry standards. It is ROHS3 compliant and carries unlimited moisture sensitivity rating (MSL 1), suitable for standard manufacturing and storage conditions.

Substitute Part: HMK432BJ105KM-T

The HMK432BJ105KM-T is a parametric equivalent that meets all electrical and mechanical specifications. However, this part is designated as "Not For New Designs," indicating it is in a mature or obsolescence phase. This substitute is appropriate for:

• Replacement or repair of existing assemblies
• Supply chain continuity when primary part availability is constrained
• Legacy product support and field service applications

Both parts are manufactured by Taiyo Yuden and share identical electrical performance characteristics, package dimensions, and compliance certifications. Selection between them should be based on product lifecycle requirements and supply availability rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can HMK432BJ105KM-T be used as a direct replacement for MSASH45MSB5105KTNA01 in new designs?

A: HMK432BJ105KM-T meets all electrical and mechanical specifications for direct substitution. However, it carries "Not For New Designs" status. New designs should specify MSASH45MSB5105KTNA01 to ensure long-term supply continuity and manufacturer support.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the 1812 (4532 Metric) package with dimensions of 0.177" L x 0.126" W (4.50mm x 3.20mm) and maximum thickness of 0.106" (2.70mm). They are mechanically interchangeable on PCB layouts.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both MSASH45MSB5105KTNA01 and HMK432BJ105KM-T carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or manufacturing processes.

Q: What is the operating temperature range for these capacitors?

A: Both parts operate across -55°C to 85°C with X5R temperature coefficient, providing stable capacitance performance across this temperature range.

Q: Are both parts RoHS compliant?

A: Yes. Both MSASH45MSB5105KTNA01 and HMK432BJ105KM-T are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: Can these parts be used interchangeably in SMPS filtering applications?

A: Yes. Both parts are specified for SMPS filtering applications and share identical electrical ratings (1 µF, 100V, X5R). They are functionally equivalent for this application.

Q: What is the difference in inventory availability?

A: MSASH45MSB5105KTNA01 has 811 pieces in stock, while HMK432BJ105KM-T has 1782 pieces available. Inventory levels should be verified at time of procurement.
