Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MMJCU31LAB7225KTPA01 are identified based on strict electrical and mechanical parameter matching. The substitution criteria include:

Electrical Parameters:

• Capacitance: 2.2 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating: 50V (exact match required)
• Temperature Coefficient: X7R (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

Mechanical Parameters:

• Package / Case: 1206 (3216 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Physical Dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm) (exact match required)
• Thickness: 0.071" (1.80mm) (exact match required)

Compliance Parameters:

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

Parts meeting all these criteria are considered direct substitutes and are electrically and mechanically interchangeable without circuit redesign or board layout modification.

Parameter Comparison

Engineering Selection Recommendations

Both the MMJCU31LAB7225KTPA01 (Taiyo Yuden) and CL31B225KBHVPJE (Samsung Electro-Mechanics) are active production parts with identical electrical and mechanical specifications. Selection between these parts is based on the following factors:

Taiyo Yuden MMJCU31LAB7225KTPA01:

• Suitable for applications requiring boardflex sensitivity, medical-grade reliability, and non-critical performance standards
• ROHS3 compliant
• MSL 1 rating (unlimited moisture sensitivity)
• Current inventory: 756 pieces

Samsung Electro-Mechanics CL31B225KBHVPJE:

• Suitable for automotive and boardflex-sensitive applications
• AEC-Q200 automotive qualification rating
• ROHS3 compliant
• REACH Unaffected status
• Current inventory: 182,620 pieces

The Samsung part includes AEC-Q200 automotive qualification, making it suitable for automotive-grade applications. The Taiyo Yuden part is specified for medical and non-critical applications. Both parts are electrically and mechanically interchangeable. Selection should be based on application requirements, supply chain availability, and any specific manufacturer qualification requirements for the end application.

Frequently Asked Questions (FAQ)

Q: Can CL31B225KBHVPJE be used as a direct replacement for MMJCU31LAB7225KTPA01?

A: Yes. Both parts are 2.2 µF, 50V, X7R ceramic capacitors in 1206 (3216 Metric) surface mount packages with identical electrical and mechanical specifications. They are electrically and mechanically interchangeable without circuit redesign or board layout modification.

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

A: Capacitance (2.2 µF), tolerance (±10%), voltage rating (50V), temperature coefficient (X7R), and operating temperature range (-55°C ~ 125°C) must all match exactly for parts to be considered direct substitutes.

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

A: Package type (1206 / 3216 Metric), mounting type (Surface Mount, MLCC), physical dimensions (0.126" L x 0.063" W / 3.20mm x 1.60mm), and maximum thickness (0.071" / 1.80mm) must all match exactly.

Q: Are there any compliance differences between these parts?

A: Both parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. The Samsung part includes AEC-Q200 automotive qualification and REACH Unaffected status, while the Taiyo Yuden part is specified for medical and non-critical applications.

Q: Does the packaging format affect substitution?

A: No. Both parts are supplied in Tape & Reel (TR) format, which is the standard packaging for surface mount components. The packaging format is identical and does not affect electrical or mechanical interchangeability.

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

A: The Taiyo Yuden MMJCU31LAB7225KTPA01 is specified for medical applications. The Samsung CL31B225KBHVPJE is specified for automotive applications with AEC-Q200 qualification. Application-specific requirements and manufacturer qualifications should be verified before substitution in medical applications.

Q: What is the significance of the X7R temperature coefficient?

A: X7R indicates a temperature coefficient of ±15% over the operating temperature range of -55°C ~ 125°C. This specification is identical for both parts and ensures stable capacitance performance across the full operating temperature range.

Q: Are there any inventory considerations for these parts?

A: The Taiyo Yuden part has 756 pieces in stock, while the Samsung part has 182,620 pieces in stock. The Samsung part offers significantly higher inventory availability for high-volume procurement requirements.
