93LC86A-I/P EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 93LC86A-I/P is a 16Kbit non-volatile EEPROM memory IC manufactured by Microchip Technology, utilizing Microwire serial interface protocol. This component operates at 3 MHz clock frequency with a 2K x 8 memory organization and is housed in an 8-PDIP through-hole package. The device is currently in active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across memory capacity, interface protocol, operating voltage range, temperature specifications, and physical packaging format.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 93LC86A-I/P is determined by strict equivalence across the following critical parameters:

• Memory capacity: 16Kbit fixed requirement
• Memory interface protocol: Microwire serial interface mandatory
• Clock frequency: 3 MHz operation
• Supply voltage range: 2.5V ~ 5.5V compatibility
• Operating temperature range: -40°C ~ 85°C minimum
• Physical package: 8-DIP through-hole form factor
• Write cycle time: 5ms specification

The 93LC86C-I/P qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility across all parameters listed above. Both devices share the same base product number (93LC86) and maintain full functional equivalence within the specified operating envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the 93LC86A-I/P and 93LC86C-I/P maintain active product status from Microchip Technology with full ROHS3 compliance and REACH unaffected classification. The 93LC86C-I/P offers expanded memory organization options (1K x 16 in addition to 2K x 8) while maintaining identical electrical performance and physical packaging. Selection between these parts should be based on application-specific memory organization requirements and component availability. Both devices satisfy identical compliance and certification requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the 93LC86C-I/P directly replace the 93LC86A-I/P in existing designs?

A: Yes. Both devices maintain identical electrical specifications, operating parameters, and 8-DIP through-hole packaging. No circuit modifications are required for substitution.

Q: What is the significance of the different memory organization options in the 93LC86C-I/P?

A: The 93LC86C-I/P supports both 2K x 8 and 1K x 16 memory organization modes. The 93LC86A-I/P operates in 2K x 8 configuration. Both organizations represent the same 16Kbit total capacity and are selectable through device configuration during operation.

Q: Are there any packaging differences between these parts?

A: No. Both parts use identical 8-DIP (0.300", 7.62mm) through-hole packages with matching pin configurations and mechanical dimensions.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 93LC86A-I/P and 93LC86C-I/P are ROHS3 compliant, REACH unaffected, and classified under identical ECCN and HTSUS codes.

Q: What is the Microwire interface protocol?

A: Microwire is a three-wire serial communication protocol consisting of chip select, clock, and data lines. Both devices operate at 3 MHz clock frequency with 5ms write cycle time specifications.
