Key Parameters

Substitute Part Grouping Explanation

Substitution of ceramic capacitors is determined by strict equivalence across electrical and mechanical parameters. The MMASU063SCG8R4DFNA01 and its identified substitute UMK063CG8R4DTHF share identical specifications in the following critical areas:

Electrical Parameters: Capacitance value of 8.4 pF with ±0.5pF tolerance, 50V rated voltage, and C0G/NP0 temperature coefficient ensure functional equivalence across the operating temperature range of -55°C to 125°C.

Mechanical Parameters: Both parts utilize the 0201 (0603 Metric) package with identical physical dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm) and maximum thickness of 0.013" (0.33mm), ensuring compatibility with existing PCB layouts and assembly processes.

Compliance Parameters: Both parts maintain ROHS3 compliance and MSL 1 rating, supporting unrestricted moisture handling and environmental regulatory requirements.

The substitute part differs in product status and application focus but maintains full electrical and mechanical compatibility for direct substitution in circuit designs.
