MMASQ21GSB7153MTNA01 Equivalent & Substitute Parts

Part Overview

The MMASQ21GSB7153MTNA01 is a 0.015 µF ceramic capacitor rated for 250V with X7R temperature coefficient, manufactured by Taiyo Yuden in 0805 (2012 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 are necessary when the primary manufacturer part becomes unavailable, when supply chain optimization is required, or when design flexibility across qualified component sources is needed while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MMASQ21GSB7153MTNA01 is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Non-Negotiable):

• Capacitance value: 0.015 µF
• Tolerance: ±20%
• Voltage rating: 250V (equal or higher)
• Temperature coefficient: X7R (ensures identical temperature stability)
• Operating temperature range: -55°C to 125°C (minimum requirement)

Mechanical Parameters (Non-Negotiable):

• Package code: 0805 (2012 Metric)
• Mounting type: Surface Mount, MLCC
• Physical dimensions: 0.079" L × 0.049" W (2.00mm × 1.25mm)
• Maximum thickness: 0.053" (1.35mm)

Compliance Parameters:

• RoHS3 compliance required
• Moisture sensitivity level: 1 (Unlimited)

Parts meeting all these parameters are classified as direct parametric equivalents and may be substituted without circuit redesign or PCB layout modification.

Engineering Selection Recommendations

Primary Part: MMASQ21GSB7153MTNA01 (Taiyo Yuden)

The MMASQ21GSB7153MTNA01 is the recommended selection for new designs. This part maintains active production status, ensuring long-term availability and supply chain stability. It carries ROHS3 compliance and is qualified for medical and non-critical applications. The part is currently in stock with 929 units available.

Substitute Part: C2012X7R2E153M125AA (TDK Corporation)

The C2012X7R2E153M125AA is a parametric equivalent that meets all electrical and mechanical specifications. However, this part carries a "Not For New Designs" status, indicating that TDK has designated it for legacy or existing design support only. This part is suitable for:

• Replacement in existing production runs
• Maintenance and repair of fielded equipment
• Supply chain diversification in established designs where design freeze has occurred

The C2012X7R2E153M125AA maintains ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility with the primary part.

Selection Criteria:

• For new product development: Use MMASQ21GSB7153MTNA01
• For existing designs requiring substitution: C2012X7R2E153M125AA is electrically and mechanically interchangeable
• Both parts are suitable for medical and non-critical applications
• No circuit redesign or PCB layout modification is required when substituting between these parts

Frequently Asked Questions (FAQ)

Q: Can C2012X7R2E153M125AA be used as a direct replacement for MMASQ21GSB7153MTNA01 in existing designs?

A: Yes. The C2012X7R2E153M125AA is a parametric equivalent with identical capacitance (0.015 µF), tolerance (±20%), voltage rating (250V), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), and package dimensions (0805/2012 Metric). No circuit modifications or PCB layout changes are required.

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

A: The "Not For New Designs" designation indicates that TDK has transitioned this part to legacy support mode. This does not affect electrical or mechanical compatibility. New designs should prioritize the MMASQ21GSB7153MTNA01 to ensure long-term supply availability and manufacturer support.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts are packaged in 0805 (2012 Metric) format with dimensions of 0.079" L × 0.049" W (2.00mm × 1.25mm) and maximum thickness of 0.053" (1.35mm). They share identical PCB footprints and mounting requirements.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the MMASQ21GSB7153MTNA01 and C2012X7R2E153M125AA are ROHS3 compliant. The TDK part additionally carries REACH unaffected status. Both parts have MSL 1 (Unlimited) moisture sensitivity rating, requiring no special handling beyond standard ESD precautions.

Q: What is the temperature stability difference between these parts?

A: Both parts use X7R temperature coefficient, which provides identical capacitance stability across the -55°C to 125°C operating range. X7R specification ensures capacitance change does not exceed ±15% across this temperature range, meeting the requirements for medical and non-critical applications.

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

A: Both parts are rated for medical applications. The MMASQ21GSB7153MTNA01 is explicitly listed for medical use. The C2012X7R2E153M125AA is rated for general purpose applications but meets all electrical and compliance requirements for medical equipment. Application suitability should be confirmed against specific medical device classification and regulatory requirements.

Q: What is the voltage derating consideration for 250V rated capacitors?

A: Both parts are rated for 250V. Actual circuit voltage should remain below the rated voltage with appropriate safety margin per design standards. The 250V rating applies to both parts identically.
