Procurement Notes

Verify the specific suffix of the part number carefully, as variants such as 82V2058BBG or 82V2058DAG may exist with different packaging or pinout configurations. Confirm availability status directly with authorized distributors, as this component family has faced discontinuation notices. Ensure that any replacement parts maintain compatibility with existing board layouts and firmware requirements before procurement.

Selection Notes

Select this component when designing systems requiring multiple T1/E1 interfaces in a compact form factor. Consider the short-haul optimization if the application involves direct cable connections without long-distance repeaters. Evaluate thermal management requirements based on the operating temperature range and power consumption specifications found in the official datasheet. Ensure the design accommodates the specific package dimensions and moisture sensitivity level indicated for the chosen variant.

Part Context

The 82V2058BB belongs to the 82V2058 series of telecom interface ICs from Renesas Electronics. This series is widely recognized for providing integrated line interface solutions for digital carrier networks. The component serves as a critical interface between digital logic circuits and physical transmission media, enabling reliable data transfer in telecommunications environments.

Replacement Considerations

Official documentation lists the 82V2058BBG as an alternate part number within the same product family. Verify pin-to-pin compatibility and electrical characteristics against the original specification sheet before substitution. Other variants like the 82V2058DAG offer different package options but require careful evaluation of mechanical fit.
