93C86B-I/P EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 93C86B-I/P is a 16Kbit non-volatile EEPROM memory integrated circuit manufactured by Microchip Technology. This device operates using the Microwire serial interface protocol at 3 MHz clock frequency and is housed in an 8-pin DIP package. The component is actively produced and maintains full RoHS3 compliance with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical specifications, memory capacity, interface protocol, and physical packaging are maintained across the product line. Alternative models may be required due to inventory availability, regional sourcing constraints, or specific packaging preferences.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 93C86B-I/P is determined by strict equivalence across the following critical parameters:

• Memory capacity: 16Kbit total storage
• Memory interface protocol: Microwire serial communication
• Clock frequency: 3 MHz operation
• Supply voltage range: 4.5V ~ 5.5V
• Operating temperature range: -40°C ~ 85°C
• Physical package: 8-DIP through-hole configuration
• Write cycle time: 2ms maximum

The 93C86C-I/P qualifies as a direct substitute, maintaining identical electrical specifications and physical packaging while supporting both 1K x 16 and 2K x 8 memory organization options. Both parts share the same base product number (93C86) and are manufactured by Microchip Technology under active product status.

Parameter Comparison

Engineering Selection Recommendations

Both the 93C86B-I/P and 93C86C-I/P maintain active product status with full RoHS3 compliance and REACH unaffected designation. Selection between these parts is based on inventory availability and packaging format preference (standard tube packaging for 93C86C-I/P). The electrical and thermal performance characteristics are equivalent, supporting direct substitution in applications requiring 16Kbit Microwire EEPROM functionality within the specified voltage and temperature operating ranges.

Frequently Asked Questions (FAQ)

Q: Can the 93C86C-I/P directly replace the 93C86B-I/P in existing designs?

A: Yes. Both parts maintain identical electrical specifications, clock frequency, supply voltage requirements, operating temperature range, and 8-DIP through-hole package configuration. The 93C86C-I/P supports both 1K x 16 and 2K x 8 memory organization, providing equivalent or expanded functionality.

Q: What are the critical parameters that determine substitution compatibility?

A: Substitution requires equivalence in memory capacity (16Kbit), interface protocol (Microwire), clock frequency (3 MHz), supply voltage (4.5V ~ 5.5V), operating temperature range (-40°C ~ 85°C), and physical package (8-DIP through-hole). Deviation in any of these parameters disqualifies a part as a direct substitute.

Q: Are there packaging differences between the main part and substitute?

A: The 93C86B-I/P and 93C86C-I/P use identical 8-DIP (0.300", 7.62mm) through-hole packages. The primary difference is supplier packaging format (tube for 93C86C-I/P), which does not affect electrical performance or PCB integration.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 93C86B-I/P and 93C86C-I/P are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. Compliance certifications are equivalent across both parts.

Q: What is the write cycle time specification for these parts?

A: Both parts specify a maximum write cycle time of 2ms for word and page operations, ensuring consistent data programming performance in applications requiring timed write operations.
