A6259KA Equivalent & Substitute Parts

Part Overview

The A6259KA is an 8-channel driver IC manufactured by Allegro MicroSystems in a 20-DIP package. This component functions as a logic driver interface for digital applications requiring multiple output channels. The A6259KA is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support, design updates, and production continuity. Equivalent parts must maintain electrical compatibility across supply voltage, operating temperature range, and package form factor to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the A6259KA is determined by strict alignment with the following critical parameters:

• Supply Voltage Range: 4.5V ~ 5.5V (exact match required)
• Operating Temperature Range: -40°C ~ 125°C (exact match required)
• Package Type: 20-DIP (0.300", 7.62mm) (exact match required)
• Driver Configuration: 8-channel output capability (exact match required)
• Mounting Technology: Through Hole (exact match required)

The TPIC6259N from Texas Instruments satisfies all substitution criteria. While the TPIC6259N is classified as an addressable latch with D-type logic architecture (differing from the A6259KA's driver classification), it maintains electrical and mechanical compatibility across all critical parameters, enabling functional equivalence in applications requiring 8-channel logic interface capability.

Parameter Comparison

Engineering Selection Recommendations

The TPIC6259N is the qualified substitute for the obsolete A6259KA based on the following engineering criteria:

Electrical Compatibility: Both components operate within the identical 4.5V to 5.5V supply voltage range and -40°C to 125°C temperature envelope, ensuring direct functional replacement without circuit modification.

Mechanical Compatibility: Both components utilize the 20-DIP (0.300", 7.62mm) through-hole package, permitting direct socket substitution on existing printed circuit boards without layout changes.

Product Status: The TPIC6259N maintains active production status with Texas Instruments, providing long-term availability and supply chain stability compared to the obsolete A6259KA.

Compliance Advantage: The TPIC6259N achieves ROHS3 compliance, offering environmental and regulatory advantages for new designs and updated production runs, whereas the A6259KA is RoHS non-compliant.

Availability: The TPIC6259N is available in higher inventory quantities (1822 units) compared to remaining A6259KA stock (874 units), supporting both immediate replacement needs and future procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the TPIC6259N directly replace the A6259KA without circuit modifications?

A: Yes. Both components share identical supply voltage (4.5V ~ 5.5V), operating temperature range (-40°C ~ 125°C), and 20-DIP package form factor. Direct socket substitution is supported without circuit redesign.

Q: What is the functional difference between the A6259KA driver and TPIC6259N addressable latch?

A: The A6259KA is classified as a driver IC, while the TPIC6259N is a D-type addressable latch with 1:8 circuit configuration. Despite different internal architectures, both components provide 8-channel output capability and operate within identical electrical and mechanical specifications, enabling functional equivalence in applications requiring multi-channel logic interface capability.

Q: Are there any compliance considerations when substituting the A6259KA with the TPIC6259N?

A: The TPIC6259N is ROHS3 compliant, whereas the A6259KA is RoHS non-compliant. For applications subject to RoHS regulations or environmental compliance requirements, the TPIC6259N provides regulatory advantage. Both components are REACH Unaffected and classified under ECCN EAR99.

Q: Does the TPIC6259N propagation delay of 625ns affect compatibility?

A: The A6259KA propagation delay specification is not provided in the component data. The TPIC6259N propagation delay of 625ns should be verified against application timing requirements to confirm suitability for the intended circuit function.

Q: What packaging options are available for the TPIC6259N?

A: The TPIC6259N is supplied in Tube packaging. The supplier device package designation is 20-PDIP, which is mechanically and electrically equivalent to the 20-DIP package used for the A6259KA.

Q: Is the A6259KA still available for procurement?

A: The A6259KA is classified as obsolete. Current inventory of 874 units is available, but long-term availability is not guaranteed. The TPIC6259N is recommended for new designs and ongoing production to ensure supply chain continuity.
