A6595KA Equivalent & Substitute Parts

Part Overview

The A6595KA is an obsolete power management IC manufactured by Allegro MicroSystems, designed as a power switch/driver with 1:8 N-channel configuration in a 20-DIP package. This latched driver IC provides low-side switching capability with 250mA output current per channel and operates across a 4.5V to 5.5V supply voltage range. Due to its obsolete product status, identifying functionally compatible substitute components is essential for system redesign, legacy product support, and continued manufacturing operations.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the A6595KA is determined by the following critical parameters:

Mechanical Compatibility:

• Package type: 20-DIP (0.300", 7.62mm) form factor for direct PCB footprint compatibility
• Mounting type: Through Hole for identical assembly process

Electrical Compatibility:

• Supply voltage range: 4.5V ~ 5.5V operation
• Output configuration: 8-bit parallel output capability
• Output type: N-Channel or Open Drain topology
• Operating temperature range: -40°C ~ 125°C minimum

Functional Compatibility:

• Serial-to-parallel conversion capability
• Low-side switching or open-drain output structure
• 8-bit output width

The TPIC6595N from Texas Instruments meets these substitution criteria through identical package geometry, matching supply voltage specifications, equivalent 8-bit output architecture, and compatible operating temperature range. Both devices utilize serial interface protocols for input control and provide parallel output switching capability suitable for power distribution and load control applications.

Engineering Selection Recommendations

The TPIC6595N represents the primary substitute for the obsolete A6595KA based on the following engineering criteria:

Product Status Alignment: The TPIC6595N maintains Active product status with ongoing manufacturer support, ensuring long-term availability and continued technical documentation access. This contrasts with the A6595KA's Obsolete classification, which restricts future procurement and support options.

Compliance Advantage: The TPIC6595N achieves ROHS3 compliance, meeting current environmental and regulatory requirements for new product designs and manufacturing operations. The A6595KA's RoHS non-compliant status may present restrictions for certain applications and markets.

Electrical and Mechanical Equivalence: Both devices share identical 20-DIP package geometry, matching 4.5V to 5.5V supply voltage specifications, 8-bit output architecture, and -40°C to 125°C operating temperature range. These parameters ensure direct functional substitution without circuit redesign.

Regulatory Alignment: Both components maintain identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, preserving export and trade compliance status.

Frequently Asked Questions (FAQ)

Q: Can the TPIC6595N directly replace the A6595KA without PCB modifications?

A: Yes. Both devices utilize identical 20-DIP (0.300", 7.62mm) package geometry and pin configuration, enabling direct PCB footprint compatibility without layout changes. Through-hole mounting type is consistent across both components.

Q: Are the supply voltage requirements identical between these devices?

A: Yes. Both the A6595KA and TPIC6595N operate across the 4.5V to 5.5V supply voltage range, ensuring compatible power supply specifications and circuit integration without modification.

Q: What is the functional difference between N-Channel output (A6595KA) and Open Drain output (TPIC6595N)?

A: Both output configurations provide low-side switching capability suitable for driving external loads. Open Drain topology (TPIC6595N) requires external pull-up resistors for high-level output definition, while N-Channel configuration (A6595KA) provides integrated switching. Circuit design must account for this output structure difference during implementation.

Q: Does the TPIC6595N support the same serial interface protocol as the A6595KA?

A: Both devices support serial-to-parallel conversion with 8-bit output capability. Specific interface protocol compatibility (Strobe, Serial) must be verified against individual device datasheets to confirm pin-level signal compatibility and timing requirements.

Q: Is the TPIC6595N suitable for new product designs?

A: Yes. The TPIC6595N's Active product status, ROHS3 compliance, and ongoing manufacturer support make it appropriate for new designs requiring 8-bit power switching or load control functionality in 20-DIP packages.

Q: What are the inventory implications of this substitution?

A: The A6595KA maintains 2008 pieces in stock as new original inventory. The TPIC6595N has 1995 pieces available. For long-term production requirements, the TPIC6595N's Active status provides superior supply chain continuity compared to the A6595KA's Obsolete classification.
