Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TMK063B7222MP-F is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance value: 2200 pF
• Voltage rating: 25V
• Temperature coefficient: X7R
• Package / Case: 0201 (0603 Metric)
• Mounting type: Surface Mount, MLCC
• Operating temperature range: -55°C ~ 125°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Allowable Variation:

• Tolerance: The substitute part may have a tighter tolerance specification (±10%) compared to the original part (±20%), provided all other parameters remain identical.

The TMK063B7222KP-F meets all mandatory matching parameters and represents a direct substitute with improved tolerance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The TMK063B7222KP-F is a direct functional equivalent to the TMK063B7222MP-F for SMPS filtering applications. Both parts share identical electrical specifications, physical dimensions, and environmental compliance certifications. The substitute part offers improved tolerance performance at ±10% compared to the original ±20% specification, which provides enhanced capacitance accuracy without introducing any compatibility concerns.

Both parts carry "Not For New Designs" status from Taiyo Yuden, indicating that neither part is recommended for new product development. For existing production lines and maintenance applications, the TMK063B7222KP-F serves as a suitable replacement with superior tolerance characteristics and higher inventory availability (31,390 units in stock versus 1,169 units for the original part).

Selection between these parts should be based on inventory requirements, lead time considerations, and tolerance specifications appropriate to the circuit design. The tighter tolerance of the substitute part does not introduce any electrical or mechanical incompatibility with existing PCB designs or assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the TMK063B7222KP-F be used as a direct replacement for the TMK063B7222MP-F in existing designs?

A: Yes. The TMK063B7222KP-F is electrically and mechanically equivalent to the TMK063B7222MP-F. Both parts have identical capacitance (2200 pF), voltage rating (25V), temperature coefficient (X7R), package dimensions (0201/0603 Metric), and operating temperature range (-55°C ~ 125°C). The substitute part features a tighter tolerance specification (±10% versus ±20%), which does not create compatibility issues.

Q: What is the primary difference between these two parts?

A: The primary difference is the capacitance tolerance specification. The TMK063B7222MP-F has ±20% tolerance, while the TMK063B7222KP-F has ±10% tolerance. This represents an improvement in capacitance accuracy for the substitute part. All other electrical and mechanical parameters are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both the TMK063B7222MP-F and TMK063B7222KP-F are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: What does "Not For New Designs" status mean?

A: "Not For New Designs" indicates that Taiyo Yuden has discontinued active development and marketing of these specific part variants. Both the original and substitute parts carry this status. For new product development, consultation with Taiyo Yuden regarding current production alternatives is recommended.

Q: Are the physical dimensions identical?

A: Yes. Both parts are packaged in 0201 (0603 Metric) format with dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum thickness of 0.015" (0.39mm). They are mechanically interchangeable on PCBs designed for this package size.

Q: What applications are these capacitors designed for?

A: Both parts are specified for SMPS (Switched-Mode Power Supply) filtering applications. The X7R temperature coefficient provides stable capacitance across the operating temperature range, making these parts suitable for power supply decoupling and filtering circuits.
