A6595KA-T Equivalent & Substitute Parts

Part Overview

The A6595KA-T is an Allegro MicroSystems power management IC functioning as an N-channel power switch driver with 1:8 output configuration. Designed for latched driver applications, this component provides 8 low-side N-channel outputs with 250mA maximum current per output and operates across a 4.5V to 5.5V supply voltage range. The device is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations where legacy component replacement is required.

Substitute Part Grouping Explanation

Substitution of the A6595KA-T is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Package format: 20-DIP (0.300", 7.62mm) for direct socket compatibility
• Supply voltage range: 4.5V ~ 5.5V
• Output configuration: 8-bit parallel output capability
• Operating temperature range: -40°C ~ 125°C minimum
• Output type: N-channel or open-drain configuration
• Mounting type: Through-hole

Regulatory & Compliance Requirements:

• RoHS3 compliance
• REACH unaffected status
• ECCN classification: EAR99

The TPIC6595N from Texas Instruments meets these substitution criteria as a shift register with 8-bit parallel output capability, identical package format, matching supply voltage specifications, and equivalent operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The TPIC6595N qualifies as a direct substitute for the A6595KA-T based on the following factors:

Package Compatibility: Both components utilize the 20-DIP (0.300", 7.62mm) package format, enabling direct socket replacement without PCB modification.

Electrical Specifications: Matching supply voltage range (4.5V ~ 5.5V) and operating temperature range (-40°C ~ 125°C) ensure functional equivalence in existing circuit designs.

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements.

Product Availability: The TPIC6595N maintains active product status with established supply chain availability, addressing the obsolescence of the A6595KA-T.

Output Configuration: The open-drain output configuration of the TPIC6595N provides functional equivalence to the N-channel output of the A6595KA-T in low-side switching applications.

Frequently Asked Questions (FAQ)

Q: Can the TPIC6595N directly replace the A6595KA-T without circuit modifications?

A: Yes. Both components share identical package format (20-DIP), supply voltage specifications (4.5V ~ 5.5V), and operating temperature range (-40°C ~ 125°C). Direct socket substitution is supported.

Q: What is the functional difference between N-channel and open-drain output configurations?

A: Both configurations operate as low-side switches. N-channel outputs use integrated MOSFET structures, while open-drain outputs require external pull-up resistors. In applications where the A6595KA-T was used with external pull-ups, the TPIC6595N provides equivalent functionality.

Q: Are there compliance differences between these components?

A: No. Both the A6595KA-T and TPIC6595N maintain ROHS3 compliance and REACH unaffected status, ensuring equivalent regulatory standing.

Q: Why is the A6595KA-T classified as obsolete?

A: Obsolescence reflects discontinuation by the original manufacturer. The TPIC6595N, maintained in active production status, provides continued availability for equivalent functionality.

Q: What is the significance of the 20-DIP package format for substitution?

A: The 20-DIP package format ensures mechanical and electrical compatibility with existing PCB designs. Both components utilize identical pin spacing (0.300", 7.62mm), enabling direct replacement without layout modifications.
