Key Parameters

Substitute Part Grouping Explanation

Substitution of the TMK107BBJ225KAHT is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Capacitance value (2.2 µF), voltage rating (25V), temperature coefficient (X5R), and tolerance (±10%) must be identical. These parameters define the functional behavior of the capacitor in the circuit.

Physical Parameters: Package designation (0603 / 1608 Metric) and mounting type (Surface Mount, MLCC) must match to ensure compatibility with existing PCB layouts and assembly processes.

Environmental Parameters: Operating temperature range (-55°C ~ 85°C) and moisture sensitivity level (MSL 1) must be maintained to ensure reliability in the intended application environment.

Compliance Parameters: AEC-Q200 automotive rating, ROHS3 compliance, and EAR99 export classification must be preserved for regulatory and supply chain requirements.

The substitute part MCAST168BB5225KTNA01 meets all these criteria and represents an active production alternative to the obsolete TMK107BBJ225KAHT.

Parameter Comparison

Engineering Selection Recommendations

The MCAST168BB5225KTNA01 is the direct equivalent substitute for the TMK107BBJ225KAHT. Both components are manufactured by Taiyo Yuden and share identical electrical, physical, and environmental specifications. The primary distinction is product status: the TMK107BBJ225KAHT is designated "Not For New Designs," while the MCAST168BB5225KTNA01 maintains active production status.

For applications currently using TMK107BBJ225KAHT, the MCAST168BB5225KTNA01 provides functional equivalence with the advantage of ongoing manufacturer support and availability. Both parts carry AEC-Q200 automotive qualification and ROHS3 compliance, ensuring regulatory requirements are maintained across the substitution.

The identical package dimensions (0603 / 1608 Metric), electrical ratings (2.2 µF, 25V, X5R), and operating temperature range (-55°C ~ 85°C) confirm direct PCB compatibility and circuit performance equivalence. No design modifications are required for this substitution.

Frequently Asked Questions (FAQ)

Q: Can MCAST168BB5225KTNA01 be used as a direct replacement for TMK107BBJ225KAHT without PCB modifications?

A: Yes. Both components share identical package dimensions (0603 / 1608 Metric), footprint, and mounting type (Surface Mount, MLCC). No PCB layout changes are required.

Q: Are the electrical characteristics identical between these two parts?

A: Yes. Capacitance (2.2 µF), voltage rating (25V), temperature coefficient (X5R), tolerance (±10%), and operating temperature range (-55°C ~ 85°C) are identical across both components.

Q: Why is TMK107BBJ225KAHT marked "Not For New Designs"?

A: This designation indicates the part has been superseded in the manufacturer's product line. MCAST168BB5225KTNA01 is the active production equivalent and should be used for new designs and ongoing procurement.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both components carry AEC-Q200 automotive rating and ROHS3 compliance, meeting automotive industry standards and regulatory requirements.

Q: Is there a difference in moisture sensitivity between these parts?

A: No. Both components have Moisture Sensitivity Level (MSL) 1, classified as "Unlimited," indicating identical handling and storage requirements.

Q: What is the physical size of these capacitors?

A: Both components measure 0.063" L x 0.031" W (1.60mm x 0.80mm) with a maximum thickness of 0.035" (0.90mm), conforming to the 0603 (1608 Metric) package standard.

Q: Are there any export or regulatory restrictions on these parts?

A: Both components are classified as EAR99 and are REACH Unaffected, indicating standard export classification and no REACH substance restrictions.
