MLASH45MSB7474KTNA01 Equivalent & Substitute Parts

Part Overview

The MLASH45MSB7474KTNA01 is a 0.47 µF ceramic capacitor rated at 100V with X7R temperature coefficient in 1812 (4532 Metric) surface mount package. This component is manufactured by Taiyo Yuden and maintains Active product status. The part is specified for medical and non-critical applications with unlimited moisture sensitivity level (MSL 1) and full RoHS3 compliance.

Substitute parts become necessary when the primary part experiences supply constraints, inventory limitations, or when design requirements permit selection from alternative qualified sources within the same electrical and mechanical specifications.

• Moisture sensitivity level: 1 (Unlimited)

The substitute part HMK432B7474KMHT 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 parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (MLASH45MSB7474KTNA01): The MLASH45MSB7474KTNA01 is the recommended choice for new designs. This part maintains Active product status from Taiyo Yuden, ensuring long-term availability and continued manufacturing support. The part is specified for medical and non-critical applications with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute Selection (HMK432B7474KMHT): The HMK432B7474KMHT is electrically and mechanically equivalent and may be used as a direct substitute when the primary part is unavailable. This part carries AEC-Q200 automotive qualification and is specified for automotive and SMPS filtering applications. However, the part is designated "Not For New Designs," indicating that Taiyo Yuden is transitioning this product line. Use of this substitute is limited to existing designs requiring component replacement or when supply of the primary part is constrained.

Both parts satisfy identical electrical specifications, mechanical dimensions, and compliance requirements. Selection between them depends on design phase (new versus existing) and application context (medical/non-critical versus automotive).

Frequently Asked Questions (FAQ)

Q: Can HMK432B7474KMHT be used as a direct replacement for MLASH45MSB7474KTNA01 in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters: 0.47 µF capacitance, ±10% tolerance, 100V rating, X7R temperature coefficient, 1812 package, and identical physical dimensions. Both maintain RoHS3 compliance and unlimited moisture sensitivity rating.

Q: Why does the substitute part have "Not For New Designs" status?

A: The HMK432B7474KMHT is designated "Not For New Designs" by Taiyo Yuden, indicating the manufacturer is discontinuing or transitioning this product line. This designation does not affect functional performance or compatibility with the primary part. New designs should specify the MLASH45MSB7474KTNA01 to ensure long-term availability.

Q: Are there differences in application focus between these parts?

A: The MLASH45MSB7474KTNA01 is specified for medical and non-critical applications. The HMK432B7474KMHT is specified for automotive and SMPS filtering applications and carries AEC-Q200 automotive qualification. These application designations reflect intended markets and qualification testing, not functional capability differences. Both parts meet identical electrical and mechanical specifications.

Q: Will the substitute part fit the same PCB footprint?

A: Yes. Both parts use the 1812 (4532 Metric) package with identical physical dimensions: 0.177" L x 0.126" W (4.50mm x 3.20mm) and maximum thickness of 0.106" (2.70mm). No PCB layout modifications are required for substitution.

Q: Are both parts RoHS3 compliant?

A: Yes. Both MLASH45MSB7474KTNA01 and HMK432B7474KMHT are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the moisture sensitivity level for both parts?

A: Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special moisture control requirements.
