Key Parameters

Substitute Part Grouping Explanation

The BD6220F-E2 qualifies as a direct substitute for the BA6208F-E2 based on the following critical parameters:

• Output Configuration: Both devices feature half bridge (2) topology
• Current Rating: Both deliver 500mA per output channel
• Package: Identical 8-SOIC (0.173", 4.40mm Width) surface mount package
• Mounting Type: Both are surface mount components
• Applications: Both support DC motor and general-purpose driver applications
• Interface: Both use logic-level control interface
• Load Type: Both handle inductive loads
• Compliance: Both are ROHS3 compliant with MSL 1 rating

The BD6220F-E2 represents an active product with enhanced specifications, including extended operating temperature range (-40°C to 85°C versus -20°C to 60°C) and integrated fault protection features (current limiting, over-temperature, over-voltage, and UVLO).

Parameter Comparison

Engineering Selection Recommendations

The BD6220F-E2 is the designated substitute for the obsolete BA6208F-E2. Both devices share identical electrical output specifications (500mA half bridge configuration), package geometry (8-SOIC), and compliance certifications (ROHS3, MSL 1).

Key considerations for substitution:

• Supply Voltage Compatibility: The BD6220F-E2 requires a minimum supply voltage of 6V, compared to 4.5V for the BA6208F-E2. Designs operating below 6V require alternative solutions.
• Operating Temperature Range: The BD6220F-E2 extends the upper operating limit to 85°C and lower limit to -40°C, providing broader environmental coverage than the original device.
• Active Product Status: The BD6220F-E2 is an active product with ongoing manufacturer support, ensuring long-term availability and supply chain stability.
• Compliance Certification: Both devices maintain ROHS3 compliance and identical MSL ratings, supporting equivalent reliability and handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the BD6220F-E2 directly replace the BA6208F-E2 in all applications?

A: Direct replacement is possible for designs operating at supply voltages of 6V or higher. Applications requiring 4.5V operation require alternative component selection, as the BD6220F-E2 minimum supply voltage is 6V.

Q: What are the key differences between these devices?

A: The primary differences are product status (obsolete versus active), internal technology (bipolar versus power MOSFET), operating temperature range (-20°C to 60°C versus -40°C to 85°C), and integrated fault protection features in the BD6220F-E2.

Q: Are the packages physically identical?

A: Yes. Both devices use the 8-SOIC (0.173", 4.40mm Width) surface mount package with identical pin configurations and PCB footprints.

Q: Do both devices meet the same compliance standards?

A: Yes. Both the BA6208F-E2 and BD6220F-E2 are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity ratings.

Q: What is the output current capability of these devices?

A: Both devices deliver 500mA per output channel in a half bridge (2) configuration, supporting equivalent load driving capacity.

Q: Why is the BD6220F-E2 considered a substitute if the minimum supply voltage differs?

A: The BD6220F-E2 qualifies as a substitute for applications operating within its specified voltage range (6V to 15V). The 6V minimum represents a practical operating point for most DC motor control applications, while the extended temperature range and active product status provide additional design benefits.
