93LC86AT-I/SN Equivalent & Substitute Parts

Part Overview

The 93LC86AT-I/SN is a 16Kbit EEPROM memory IC manufactured by Microchip Technology, utilizing Microwire serial interface protocol. This non-volatile memory device operates at 3 MHz clock frequency with a 2K x 8 memory organization, housed in an 8-SOIC surface mount package. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same memory category and interface standard.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 93LC86AT-I/SN is determined by strict equivalence across the following critical parameters:

• Memory capacity: 16Kbit with 2K x 8 organization
• Serial interface protocol: Microwire standard
• Clock frequency: 3 MHz operation
• Supply voltage compatibility: 2.5V ~ 5.5V range
• Temperature rating: -40°C ~ 85°C operational envelope
• Package footprint: 8-SOIC form factor with identical pin configuration
• Compliance certifications: ROHS3 and REACH status alignment

The 93LC86A-I/SN qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. Packaging format differences (Tape & Reel versus Tube) do not affect functional substitution but may impact procurement and handling procedures.

Parameter Comparison

Engineering Selection Recommendations

Both the 93LC86AT-I/SN and 93LC86A-I/SN are active production parts from Microchip Technology with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on packaging and procurement requirements rather than functional performance, as all electrical and mechanical specifications are identical. The 93LC86A-I/SN offers higher inventory availability (3400 units) compared to the main part (1182 units). Packaging format selection (Tape & Reel versus Tube) depends on assembly line automation capabilities and component handling infrastructure.

Frequently Asked Questions (FAQ)

Q: Can the 93LC86A-I/SN be used as a direct replacement for the 93LC86AT-I/SN in existing designs?

A: Yes. Both parts share identical electrical specifications, memory capacity, interface protocol, and 8-SOIC package footprint. Pin configuration and functional behavior are equivalent.

Q: What is the difference between Tape & Reel and Tube packaging?

A: Tape & Reel packaging is optimized for automated pick-and-place assembly equipment, while Tube packaging is suitable for manual handling and lower-volume assembly processes. Both formats contain the same component with identical specifications.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical ROHS3 compliance, REACH unaffected status, MSL rating of 1 (Unlimited), and active production status.

Q: What are the critical parameters that define substitution eligibility for this EEPROM?

A: Substitution is valid when the following parameters match: 16Kbit memory capacity, 2K x 8 organization, Microwire interface, 3 MHz clock frequency, 2.5V ~ 5.5V supply voltage range, -40°C ~ 85°C operating temperature, and 8-SOIC package form factor.

Q: Can parts with different memory sizes or interface protocols substitute for the 93LC86AT-I/SN?

A: No. Memory capacity, organization, and interface protocol are non-negotiable substitution criteria. Parts with different specifications require complete design re-evaluation and are not considered equivalent substitutes.
