TMK107BBJ475MA-T Equivalent & Substitute Parts

Part Overview

The TMK107BBJ475MA-T is a 4.7 µF ceramic capacitor rated at 25V with X5R temperature coefficient in 0603 (1608 Metric) surface mount package. This component is manufactured by Taiyo Yuden and is designated as Not For New Designs, indicating it has been superseded in the manufacturer's product line. The part is widely used in SMPS filtering applications where stable capacitance across temperature ranges and compact form factors are required. Due to its obsolescence status, identifying equivalent substitute parts with identical electrical and mechanical specifications is essential for design continuity and procurement planning.

Engineering Selection Recommendations

MSAST168BB5475MTNA01 (Taiyo Yuden)

This substitute is a direct equivalent from the same manufacturer. The MSAST168BB5475MTNA01 maintains identical electrical and mechanical specifications while offering Active product status, indicating ongoing manufacturing support and availability. This part is preferred for applications requiring continuity with the original Taiyo Yuden supply chain. ROHS3 compliance and MSL 1 rating ensure compatibility with standard assembly processes.

KGM15CR51E475MT (KYOCERA AVX)

This substitute provides equivalent performance from an alternative manufacturer. The KGM15CR51E475MT series delivers identical capacitance, voltage, temperature coefficient, and package specifications. Active product status from KYOCERA AVX ensures long-term availability. This option is suitable for applications where multi-source qualification is required or when Taiyo Yuden supply is constrained. ROHS3 compliance and MSL 1 rating match the original part requirements.

Both substitutes are suitable for direct replacement in SMPS filtering applications and general purpose circuits without modification to circuit design or PCB layout.

Frequently Asked Questions (FAQ)

Q: Can MSAST168BB5475MTNA01 be used as a direct replacement for TMK107BBJ475MA-T?

A: Yes. Both parts share identical electrical specifications (4.7 µF, ±20%, 25V, X5R, -55°C ~ 85°C), mechanical dimensions (0603 package, 1.60mm x 0.80mm x 1.00mm max), and compliance certifications (ROHS3, MSL 1). The parts are functionally and mechanically interchangeable without circuit or layout changes.

Q: What is the difference between the TMK107BBJ475MA-T and MSAST168BB5475MTNA01?
