MSASH105SB7331MFNA01 Equivalent & Substitute Parts

Part Overview

The MSASH105SB7331MFNA01 is a 330 pF ceramic capacitor manufactured by Taiyo Yuden, rated for 100V operation with X7R temperature coefficient characteristics. This surface-mount multilayer ceramic capacitor (MLCC) in 0402 package format is designed for general-purpose applications requiring stable capacitance across the -55°C to 125°C operating temperature range.

The part is currently in Active product status with 968 units available in inventory. Substitute parts become necessary when the primary part reaches end-of-life, inventory constraints occur, or design requirements necessitate alternative sourcing options while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the MSASH105SB7331MFNA01 is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Capacitance value: 330 pF
• Tolerance: ±20%
• Voltage rating: 100V
• Temperature coefficient: X7R
• Operating temperature range: -55°C to 125°C

Mechanical Parameters (Must Match Exactly):

• Package type: 0402 (1005 Metric)
• Mounting type: Surface Mount, MLCC
• Maximum thickness: 0.022" (0.55mm)

Compliance Parameters (Must Match or Exceed):

• RoHS3 Compliance
• Moisture Sensitivity Level: 1 (Unlimited)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. Variations in product status, series designation, or application classification do not affect substitution eligibility when all electrical, mechanical, and compliance parameters are identical.

Engineering Selection Recommendations

Primary Selection: MSASH105SB7331MFNA01

The MSASH105SB7331MFNA01 is the recommended choice for new designs. This part carries Active product status, indicating ongoing manufacturer support and availability. With 968 units in current inventory, supply continuity is established. The part meets all regulatory requirements including ROHS3 compliance and REACH unaffected status.

Substitute Selection: HMK105B7331MV-F

The HMK105B7331MV-F is a parametric equivalent substitute when the primary part is unavailable. All electrical specifications, mechanical dimensions, and compliance certifications are identical to the main part. However, this substitute carries "Not For New Designs" product status, indicating the manufacturer has transitioned this part to legacy support. The substitute is suitable for replacement, repair, or continuation of existing designs where the primary part cannot be sourced.

Both parts are manufactured by Taiyo Yuden and share identical electrical performance characteristics, package footprint, and regulatory compliance status. Selection between these parts should be based on availability and design phase requirements rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can HMK105B7331MV-F be used as a direct replacement for MSASH105SB7331MFNA01 in existing designs?

A: Yes. All electrical parameters, mechanical dimensions, and compliance certifications are identical. The parts are pin-compatible and footprint-compatible with no design modifications required.

Q: Why does the substitute part have "Not For New Designs" status while the main part is Active?

A: Product status reflects the manufacturer's lifecycle management strategy. The substitute part remains available for existing designs and replacements but is not recommended for new product development. The main part should be used for new designs to ensure long-term availability and manufacturer support.

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

A: No. Both parts have identical capacitance (330 pF), tolerance (±20%), voltage rating (100V), temperature coefficient (X7R), and operating temperature range (-55°C to 125°C). Performance in circuit operation is equivalent.

Q: What is the significance of the different series designations (MSAS vs. M)?

A: Series designation reflects internal manufacturer product line organization but does not affect electrical or mechanical compatibility. Both series use identical specifications for this capacitance and voltage rating.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. Both parts use the 0402 (1005 Metric) package with identical dimensions (0.039" L x 0.020" W, 0.022" max thickness). They share the same PCB footprint and can be assembled using identical reflow profiles and handling procedures.

Q: What is the moisture sensitivity level, and does it affect storage?

A: Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity. Standard storage conditions without desiccant requirements are acceptable. No special moisture control measures are necessary during handling or storage.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected. They meet current environmental and regulatory requirements for commercial and industrial applications.
