BA6423AF-E2 Equivalent & Substitute Parts

Part Overview

The BA6423AF-E2 is a bipolar motor driver integrated circuit manufactured by ROHM Semiconductor, designed for brushless DC (BLDC) and stepper motor applications. This device integrates control and power stage functionality in a compact 8-SOP package, operating across a 6V to 28V supply range with 1A output current capability. The part carries a "Not For New Designs" product status, indicating that ROHM has discontinued active development and support for this component. This status necessitates identification of equivalent alternatives for ongoing production, maintenance, and new platform development where legacy compatibility is not required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BA6423AF-E2 is determined by strict alignment across the following critical parameters:

Motor driver functionality requires matching motor type support (bipolar stepper and BLDC capability), output configuration (half bridge topology with 2 outputs), and integrated control-power stage architecture. Electrical performance must maintain the 1A output current specification and 6V to 28V supply voltage range to ensure compatibility with existing power distribution and load requirements. Package and mounting specifications must match the 8-SOP surface mount form factor to enable direct board-level substitution without redesign. Operating temperature range (-40°C to 100°C) and interface type (logic-level control) establish the environmental and signal compatibility baseline. Compliance certifications (ROHS3, REACH Unaffected) ensure regulatory alignment for the target application market.

Based on the provided input data, the BA6423AF-E2 is identified as a parametric equivalent to itself, indicating no alternative part numbers with differing specifications are currently documented in the substitute list.

Engineering Selection Recommendations

The BA6423AF-E2 carries a "Not For New Designs" product status from ROHM Semiconductor. This designation indicates the component is in end-of-life phase with no active development roadmap. For applications currently using this device, continued sourcing from existing inventory is viable for near-term production cycles. For new platform development or long-term production commitments, evaluation of alternative bipolar motor driver solutions with equivalent electrical and mechanical specifications is recommended to ensure supply chain continuity and manufacturer support.

Component selection must prioritize ROHS3 compliance and REACH regulatory alignment to maintain market access. The 8-SOP package footprint and surface mount technology are fixed requirements for direct board-level compatibility. Electrical parameters—1A output current, 6V to 28V supply range, and -40°C to 100°C operating temperature—establish the minimum performance envelope for functional equivalence.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the BA6423AF-E2?

A: A valid substitute must support bipolar stepper and brushless DC motor types, provide half-bridge output configuration with 2 outputs, deliver 1A output current, operate across 6V to 28V supply voltage, maintain -40°C to 100°C temperature range, use 8-SOP surface mount packaging, and comply with ROHS3 and REACH requirements.

Q: Can the BA6423AF-E2 be replaced with a different package type?

A: No. The 8-SOP package is a fixed requirement for direct board-level substitution. Alternative packages would require PCB redesign and are not considered direct equivalents.

Q: Is the BA6423AF-E2 suitable for new product designs?

A: The "Not For New Designs" status indicates ROHM has discontinued active support. While existing inventory may be available, new designs should evaluate alternative motor driver solutions with active manufacturer support and extended product lifecycles.

Q: What is the significance of ROHS3 compliance for this component?

A: ROHS3 compliance certifies the device meets European Union Restriction of Hazardous Substances regulations, ensuring the component is free from restricted materials and suitable for markets with environmental compliance requirements.

Q: Does the BA6423AF-E2 support both stepper and BLDC motor types?

A: Yes. The device is specified for bipolar stepper motor control and brushless DC motor applications, providing integrated functionality for both motor types within the same package.
