93C86A-I/P EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 93C86A-I/P is a 16Kbit non-volatile EEPROM memory integrated circuit manufactured by Microchip Technology. This device implements the Microwire serial interface protocol and operates at 3 MHz clock frequency. The component is housed in an 8-pin DIP package suitable for through-hole mounting applications. The part maintains active product status with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical specifications, memory capacity, interface protocol, and package configuration are maintained across alternative manufacturer part numbers or variants within the same product family.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 93C86A-I/P is determined by strict equivalence across the following critical parameters: memory capacity (16Kbit), memory organization (2K x 8 minimum), Microwire serial interface protocol, 3 MHz clock frequency, 2ms write cycle time, 4.5V to 5.5V supply voltage range, -40°C to 85°C operating temperature range, and 8-pin DIP through-hole package configuration. The identified substitute part 93C86C-I/P maintains all specified electrical and mechanical parameters while differing only in packaging format (tube versus standard packaging) and inventory source designation. Both parts are manufactured by Microchip Technology and carry identical RoHS3 and REACH compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 93C86A-I/P and 93C86C-I/P are active products with identical electrical specifications and compliance certifications. Selection between these parts is based on packaging format and inventory availability rather than functional differences. The 93C86A-I/P is supplied in standard packaging with 1063 units in stock. The 93C86C-I/P is supplied in tube packaging with 819 units in stock. Both parts satisfy ROHS3 and REACH compliance requirements for applications requiring non-volatile serial EEPROM memory with Microwire interface protocol. The identical operating parameters ensure direct functional interchangeability in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the 93C86C-I/P directly replace the 93C86A-I/P in existing designs?

A: Yes. Both parts maintain identical electrical specifications, memory capacity, interface protocol, clock frequency, supply voltage range, operating temperature range, and 8-pin DIP package configuration. Direct substitution is functionally equivalent.

Q: What is the difference between the 93C86A-I/P and 93C86C-I/P?

A: The primary difference is packaging format. The 93C86A-I/P uses standard packaging while the 93C86C-I/P uses tube packaging. The 93C86C-I/P also supports an additional memory organization option (1K x 16) in addition to the standard 2K x 8 configuration, though both default to 2K x 8 operation.

Q: Are both parts RoHS compliant?

A: Yes. Both the 93C86A-I/P and 93C86C-I/P are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the Microwire interface protocol?

A: Microwire is a three-wire serial communication protocol consisting of chip select, clock, and data lines. The 93C86A-I/P and 93C86C-I/P operate at 3 MHz clock frequency with 2ms write cycle time for word and page operations.

Q: Can these parts be used in new designs?

A: Yes. Both parts maintain active product status from Microchip Technology, confirming ongoing manufacturing and support for new design implementations.
