Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 93C86C-E/ST is determined by strict alignment of the following parameters:

• Memory Capacity: 16Kbit (non-negotiable)
• Memory Organization: 2K x 8 or 1K x 16 configuration support
• Serial Interface Protocol: Microwire standard
• Package Form Factor: 8-TSSOP with 0.173" (4.40mm) width
• Surface Mount Compatibility: TSSOP package mounting
• Supply Voltage Range: Must encompass or be compatible with 4.5V ~ 5.5V operation
• Temperature Rating: -40°C to 125°C minimum
• Regulatory Compliance: ROHS3 and REACH compliance maintained

The substitute part CAV93C86YE-GT3 meets all primary substitution criteria while offering extended supply voltage range (2.5V ~ 5.5V) and automotive-grade qualification (AEC-Q100).

Parameter Comparison

Engineering Selection Recommendations

Both the 93C86C-E/ST and CAV93C86YE-GT3 maintain active product status and full regulatory compliance (ROHS3, REACH). The CAV93C86YE-GT3 provides automotive-grade qualification (AEC-Q100) and extended supply voltage range (2.5V ~ 5.5V), making it suitable for applications requiring broader voltage tolerance or automotive-qualified components. The 93C86C-E/ST operates at 3 MHz clock frequency versus 2 MHz for the substitute, a consideration for timing-critical applications. Both devices share identical memory capacity, organization, Microwire interface, temperature rating, and 8-TSSOP package specifications, ensuring direct functional compatibility in standard industrial applications.

Frequently Asked Questions (FAQ)

Q: Can CAV93C86YE-GT3 directly replace 93C86C-E/ST in existing designs?

A: Yes, provided the application operates within the 4.5V ~ 5.5V supply range. The CAV93C86YE-GT3 supports this voltage window and maintains identical memory capacity, organization, Microwire interface, temperature rating, and 8-TSSOP package form factor.

Q: What is the significance of the 3 MHz versus 2 MHz clock frequency difference?

A: The 93C86C-E/ST operates at 3 MHz while CAV93C86YE-GT3 operates at 2 MHz. Applications with strict timing requirements must verify that 2 MHz operation meets performance specifications before substitution.

Q: Does the extended voltage range of CAV93C86YE-GT3 (2.5V ~ 5.5V) provide any advantage?

A: The extended lower voltage limit (2.5V versus 4.5V) enables operation in low-power or battery-backed applications. However, this advantage applies only if the application design supports voltages below 4.5V.

Q: Are both parts suitable for automotive applications?

A: The CAV93C86YE-GT3 carries AEC-Q100 automotive qualification. The 93C86C-E/ST does not specify automotive qualification. For automotive designs, CAV93C86YE-GT3 is the qualified choice.

Q: Is the 8-TSSOP package identical between both parts?

A: Yes. Both devices use 8-TSSOP packaging with 0.173" (4.40mm) width, ensuring identical PCB footprint and mounting compatibility.

Q: What compliance certifications apply to both parts?

A: Both the 93C86C-E/ST and CAV93C86YE-GT3 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating.
