Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 93C86C-E/SN is determined by the following critical parameters:

Primary Compatibility Criteria:

• Memory capacity: 16Kbit
• Memory interface protocol: Microwire serial interface
• Package type: 8-SOIC surface mount
• Memory organization: 2K x 8 or 1K x 16 bit configuration
• Operating temperature range: -40°C to 125°C minimum

Secondary Compatibility Considerations:

• Supply voltage range (must encompass or match 4.5V ~ 5.5V requirement)
• Clock frequency (3 MHz nominal, lower frequencies acceptable for timing-non-critical applications)
• Write cycle time (2ms or longer acceptable)
• RoHS and regulatory compliance status

Substitute parts identified below meet all primary criteria and maintain functional equivalence within the specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Highest Compatibility): The 93C86-E/SN from Microchip Technology is the direct equivalent, matching all electrical parameters including 3 MHz clock frequency and 2ms write cycle time. This part is verified as DiGi-Electronics programmable and maintains identical supply voltage specifications (4.5V ~ 5.5V).

Extended Supply Voltage Range Alternatives: The 93LC86C-E/SN (Microchip Technology) and CAV93C86VE-GT3 (onsemi) both support extended lower voltage operation (2.5V ~ 5.5V), providing flexibility for mixed-voltage system designs. The 93LC86C-E/SN operates at 3 MHz with 5ms write cycle time. The CAV93C86VE-GT3 operates at 2 MHz and includes automotive-grade qualification (AEC-Q100).

Automotive-Qualified Alternatives: The CAV93C86VE-GT3 (onsemi) and M93C86-RMN3TP/K (STMicroelectronics) both carry AEC-Q100 automotive qualification. The M93C86-RMN3TP/K provides the widest supply voltage range (1.8V ~ 5.5V) and is available in highest inventory quantity (12,900 pcs).

Selection Criteria by Application:

• Industrial standard voltage (4.5V ~ 5.5V) with fastest write cycle: 93C86-E/SN
• Mixed-voltage systems: 93LC86C-E/SN or CAV93C86VE-GT3
• Automotive applications: CAV93C86VE-GT3 or M93C86-RMN3TP/K
• Low-voltage systems (below 2.5V): M93C86-RMN3TP/K

Frequently Asked Questions (FAQ)

Q: Can 93LC86C-E/SN replace 93C86C-E/SN in all applications? A: The 93LC86C-E/SN is functionally compatible for applications operating within the 4.5V ~ 5.5V range. The extended lower voltage specification (2.5V minimum) provides additional design flexibility. The 5ms write cycle time is longer than the 2ms specification of the 93C86C-E/SN; verify timing requirements for your application.

Q: What is the difference between automotive-grade parts (CAV93C86VE-GT3, M93C86-RMN3TP/K) and industrial-grade parts? A: Automotive-grade parts carry AEC-Q100 qualification, indicating compliance with automotive reliability and quality standards. These parts are suitable for automotive and high-reliability applications. Industrial-grade parts (93C86-E/SN, 93LC86C-E/SN) meet standard industrial specifications and are appropriate for general industrial and consumer applications.

Q: Are all substitute parts pin-compatible? A: Yes. All listed substitute parts use the 8-SOIC package with identical pinout and mechanical dimensions (0.154", 3.90mm width). Direct PCB footprint compatibility is maintained across all substitutes.

Q: Which substitute offers the lowest minimum supply voltage? A: The M93C86-RMN3TP/K supports operation down to 1.8V, providing the widest supply voltage range (1.8V ~ 5.5V). This part is suitable for low-power and battery-operated applications.

Q: Does clock frequency difference affect compatibility? A: The 93C86C-E/SN operates at 3 MHz. Substitute parts operating at 2 MHz (CAV93C86VE-GT3, M93C86-RMN3TP/K) are compatible for applications where the lower clock frequency meets timing requirements. Verify that your system design does not require the higher 3 MHz frequency before selecting 2 MHz alternatives.

Q: What is the significance of write cycle time differences? A: The 93C86C-E/SN specifies 2ms write cycle time. Substitutes with 5ms write cycle time (93LC86C-E/SN, M93C86-RMN3TP/K) require longer intervals between write operations. Verify that your application firmware accommodates the extended write cycle time before substitution.
