Key Parameters

Substitute Part Grouping Explanation

Substitution of the TMK107AB7105MAHT is determined by strict equivalence across the following parameters:

Electrical Parameters:

• Capacitance value: 1 µF
• Tolerance: ±20%
• Voltage rating: 25V (minimum)
• Temperature coefficient: X7R

Mechanical Parameters:

• Package: 0603 (1608 Metric)
• Mounting type: Surface Mount, MLCC
• Physical dimensions compatible with 0603 footprint

Compliance & Certification:

• AEC-Q200 automotive rating
• ROHS3 compliance
• Moisture Sensitivity Level 1

The substitute part MCAST168AB7105MTNA01 meets all these criteria and is manufactured by the same supplier (Taiyo Yuden), ensuring electrical and mechanical compatibility with the original design.

Parameter Comparison

Engineering Selection Recommendations

The MCAST168AB7105MTNA01 is the direct substitute for TMK107AB7105MAHT based on the following engineering criteria:

Electrical Compatibility: Both parts are identical in capacitance (1 µF), tolerance (±20%), voltage rating (25V), and temperature coefficient (X7R). Operating temperature ranges are equivalent at -55°C ~ 125°C.

Mechanical Compatibility: Both components use the 0603 (1608 Metric) surface mount package with identical footprint dimensions (0.063" L x 0.031" W). The substitute part has a slightly lower maximum thickness (0.035" vs 0.037"), which presents no compatibility issues for standard PCB designs.

Compliance & Certification: Both parts carry AEC-Q200 automotive qualification, ROHS3 compliance, and Moisture Sensitivity Level 1 (unlimited shelf life). These certifications ensure the substitute meets the same reliability and environmental standards as the original part.

Product Status Advantage: The substitute part (MCAST168AB7105MTNA01) holds Active product status, ensuring long-term availability and continued manufacturing support, whereas the original part is classified as Not For New Designs.

Frequently Asked Questions (FAQ)

Q: Can MCAST168AB7105MTNA01 be used as a direct replacement for TMK107AB7105MAHT?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters: 1 µF capacitance, ±20% tolerance, 25V rating, X7R temperature coefficient, and 0603 package. Both carry AEC-Q200 automotive certification and ROHS3 compliance.

Q: Are there any physical differences between these parts?

A: The substitute part has a maximum thickness of 0.035" compared to 0.037" for the original. This 0.002" difference is within standard PCB design tolerances and presents no compatibility issues for standard surface mount assembly processes.

Q: What is the significance of the product status difference?

A: The original part (TMK107AB7105MAHT) is marked Not For New Designs, indicating it has been superseded. The substitute (MCAST168AB7105MTNA01) is Active, ensuring continued manufacturing availability and long-term supply chain support.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both parts carry AEC-Q200 certification, confirming they meet automotive-grade reliability and performance standards.

Q: Are moisture sensitivity levels the same?

A: Yes. Both parts have Moisture Sensitivity Level 1 (Unlimited), meaning they have unlimited shelf life and do not require special moisture control handling during storage or assembly.

Q: Can the substitute part be used in existing designs without PCB modifications?

A: Yes. The substitute part uses the identical 0603 (1608 Metric) footprint and has compatible physical dimensions, requiring no PCB layout changes.
