BA4558RFVT-E2 Equivalent & Substitute Parts Reference

Part Overview

The BA4558RFVT-E2 from Rohm Semiconductor is a general-purpose dual operational amplifier in an 8-TSSOP package, suitable for surface-mount applications in the linear amplifiers category. The part features a slew rate of 1V/µs, a gain bandwidth product of 2 MHz, and a wide operating supply range (8V to 30V), making it adaptable to a range of general amplifier circuits. However, with its part status noted as "Not For New Designs," it is necessary to identify functionally equivalent or substitute parts to ensure continued manufacturability and support for new or ongoing projects requiring similar electrical and mechanical performance.

Substitute Part Grouping Explanation

Substitute parts are identified strictly using the following parameters: amplifier type (general purpose), dual circuit configuration, comparable electrical characteristics (slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, supply voltage range), mechanical compatibility (surface mount, package/case), and compliance (RoHS3, REACH). Only devices matching these criteria—without deviations or assumptions—are included. Package compatibility is ensured with the 8-TSSOP or equivalent form factors.

Engineering Selection Recommendations

For replacing BA4558RFVT-E2, select parts with identical or comparable electrical characteristics, mechanical compatibility (surface mount 8-pin TSSOP or equivalent), and regulatory compliance (RoHS3, REACH unaffected). Only alternates with the same or better compliance status and appropriate MSL grade are included. AEC-Q100 qualified substitutes are available where automotive qualification is required.

Frequently Asked Questions (FAQ)

Q1: What are the most crucial parameters for selecting a substitute for BA4558RFVT-E2?
A1: Key parameters include amplifier type (general purpose), dual circuit configuration, slew rate, gain bandwidth product, supply voltage range, input offset voltage, input bias current, supply current, operating temperature range, mounting type, and package (8-TSSOP or mechanically compatible).

Q2: Can substitutes in different package types be used?
A2: Substitution is considered only when the package is 8-TSSOP or closely matches the footprint and mechanical outline required for the application.

Q3: Are all listed substitutes compliant with RoHS3 and REACH?
A3: All listed substitutes indicate RoHS3 compliance and REACH unaffected status as per provided data.

Q4: What if my design requires automotive qualification?
A4: Devices specified as AEC-Q100 qualified, such as certain LM258 and LM2904 variants, are included for applications requiring automotive-grade components.

Q5: Do substitutes maintain supply voltage and temperature requirements?
