MMASH105SB7331MFCA01 Equivalent & Substitute Parts

Part Overview

The MMASH105SB7331MFCA01 is a 330 pF ceramic capacitor manufactured by Taiyo Yuden, rated for 100V with X7R temperature coefficient in 0402 (1005 Metric) surface mount package. This multilayer ceramic capacitor (MLCC) is designed for medical and non-critical applications requiring stable capacitance across operating temperatures from -55°C to 125°C. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts become necessary when the primary part experiences supply constraints, inventory limitations, or when design requirements permit selection from alternative manufacturers or product series within equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MMASH105SB7331MFCA01 is determined by strict equivalence across the following parameters:

Mandatory Matching Parameters:

• Capacitance: 330 pF
• Tolerance: ±20%
• Voltage Rating: 100V
• Temperature Coefficient: X7R
• Operating Temperature Range: -55°C to 125°C
• Package: 0402 (1005 Metric)
• Mounting Type: Surface Mount, MLCC
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part HMK105B7331MV-F meets all mandatory parameters and is therefore classified as a parametric equivalent. This part is manufactured by Taiyo Yuden under a different product series (M series versus MMAS series) and carries a "Not For New Designs" product status, indicating it remains available for replacement and maintenance applications but is not recommended for new product development.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (MMASH105SB7331MFCA01): The MMASH105SB7331MFCA01 is the recommended choice for new product designs. This part carries active product status from Taiyo Yuden, indicating ongoing manufacturing support and long-term availability. It is ROHS3 compliant and suitable for medical and non-critical applications. Current inventory of 925 pieces supports immediate procurement for development and production phases.

Substitute Part Selection (HMK105B7331MV-F): The HMK105B7331MV-F is suitable for replacement, maintenance, and repair applications where the primary part is unavailable. Although marked "Not For New Designs," this part maintains full electrical and mechanical equivalence to the primary part and carries identical compliance certifications (ROHS3, MSL 1). The higher inventory level (21,865 pieces) may provide supply advantages for legacy system support. This part is appropriate for field replacements and retrofit applications where design changes are not feasible.

Both parts are manufactured by Taiyo Yuden and share identical electrical performance characteristics, physical dimensions, and regulatory compliance status. Selection between them should be based on product lifecycle phase and supply availability rather than technical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can HMK105B7331MV-F be used as a direct replacement for MMASH105SB7331MFCA01 in existing designs?

A: Yes. Both parts are parametric equivalents with identical capacitance (330 pF), voltage rating (100V), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), package dimensions (0402/1005 Metric), and compliance certifications (ROHS3, MSL 1). Direct substitution is electrically and mechanically compatible.

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

A: Product status reflects Taiyo Yuden's manufacturing roadmap and long-term availability commitments. "Not For New Designs" indicates the HMK105 series is in mature or declining production phase. For new product development, the MMASH105SB7331MFCA01 (active status) is preferred to ensure sustained supply and manufacturing support throughout the product lifecycle.

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

A: No. Both parts share identical electrical specifications, temperature coefficients, voltage ratings, and moisture sensitivity levels. Reliability characteristics are determined by the common parameters listed in the Key Parameters table. Performance in circuit operation is equivalent.

Q: What is the significance of the different series designations (MMAS versus M)?

A: Series designation reflects Taiyo Yuden's internal product categorization and manufacturing lines. The MMAS series represents current-generation products, while the M series represents earlier product generations. Both series meet the same electrical and mechanical specifications for this 330 pF, 100V, X7R capacitor in 0402 package.

Q: Can these parts be mixed in the same production batch?

A: Yes, provided the application permits component substitution. Both parts are supplied in Tape & Reel (TR) packaging with identical MSL 1 (Unlimited) moisture sensitivity ratings. Assembly processes, reflow profiles, and handling procedures are identical. However, design documentation and bill of materials should clearly specify which part number is authorized for use.

Q: What are the key parameters that must match for substitution?

A: Substitution requires matching of capacitance (330 pF), tolerance (±20%), voltage rating (100V), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), package type (0402/1005 Metric), mounting type (Surface Mount MLCC), and compliance certifications (ROHS3, MSL 1). Deviation in any of these parameters disqualifies a part as a direct substitute.
