Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 93AA86A-I/P is determined by strict equivalence across the following critical parameters: 16Kbit memory capacity, Microwire serial interface protocol, 3 MHz clock frequency, 5ms write cycle time, 8-DIP through-hole package configuration, and -40°C to 85°C operating temperature range. The 93LC86C-I/P qualifies as a direct substitute based on identical memory specifications, interface protocol, clock frequency, write timing, package form factor, and temperature rating. Voltage supply range represents the primary technical distinction: the 93AA86A-I/P supports extended low-voltage operation from 1.8V, while the 93LC86C-I/P operates within 2.5V to 5.5V. This voltage differential determines application suitability in systems requiring sub-2.5V supply rails.

Parameter Comparison

Engineering Selection Recommendations

Both the 93AA86A-I/P and 93LC86C-I/P maintain Active product status with identical RoHS3 compliance and REACH unaffected classification, ensuring regulatory equivalence for industrial and commercial applications. Selection between these parts depends exclusively on system voltage supply requirements. The 93AA86A-I/P is the appropriate choice for applications requiring operation below 2.5V supply voltage. The 93LC86C-I/P is suitable for systems operating within the 2.5V to 5.5V range and offers higher inventory availability. Both components are manufactured by Microchip Technology and provide identical functional performance within their respective voltage operating windows.

Frequently Asked Questions (FAQ)

Q: Can the 93LC86C-I/P replace the 93AA86A-I/P in all applications?

A: The 93LC86C-I/P is functionally equivalent only in systems where the supply voltage remains at or above 2.5V. Applications requiring operation below 2.5V must use the 93AA86A-I/P due to its extended low-voltage specification of 1.8V minimum.

Q: Are the memory organization differences between these parts significant?

A: The 93LC86C-I/P supports dual memory organization modes (2K x 8 and 1K x 16), while the 93AA86A-I/P is specified as 2K x 8. Both configurations deliver identical 16Kbit total capacity and are compatible with standard Microwire protocol implementations.

Q: Do these parts require different PCB footprints?

A: No. Both components use identical 8-DIP (0.300", 7.62mm) through-hole package geometry and are pin-compatible for direct board-level substitution.

Q: What is the significance of the packaging difference listed for these parts?

A: The 93AA86A-I/P is supplied in standard packaging, while the 93LC86C-I/P is supplied in Tube packaging. This distinction affects only procurement and handling procedures and does not impact electrical or mechanical compatibility.

Q: Are both parts suitable for extended temperature range applications?

A: Yes. Both the 93AA86A-I/P and 93LC86C-I/P operate across the identical -40°C to 85°C temperature range and are suitable for industrial applications requiring extended temperature performance.
