Substitute Part Grouping Explanation

Substitution eligibility for the 93LC76-I/SN is determined by strict equivalence across the following critical parameters:

  • Memory capacity: 8Kbit with identical 1K x 8 or 512 x 16 organization
  • Serial interface protocol: Microwire at 3 MHz clock frequency
  • Write cycle timing: 5ms word/page write cycle time
  • Physical packaging: 8-SOIC surface mount configuration with matching 0.154" width
  • Supply voltage compatibility: Minimum 2.5V operation required
  • Temperature range: -40°C to 85°C operating specification
  • Compliance certifications: ROHS3 and REACH status alignment

The 93LC76C-I/SN qualifies as a direct substitute based on matching all electrical and mechanical parameters within the Microchip 93LC76 product family.

Engineering Selection Recommendations

Both the 93LC76-I/SN and 93LC76C-I/SN are active production components from Microchip Technology with full ROHS3 compliance and REACH unaffected status. The primary distinction is the maximum supply voltage specification: the 93LC76-I/SN supports 6.0V operation while the 93LC76C-I/SN is rated to 5.5V maximum. Selection between these parts depends on the application's supply voltage requirements. For systems operating at or above 5.5V but below 6.0V, the 93LC76-I/SN is the appropriate choice. For applications with supply voltages not exceeding 5.5V, either part is functionally equivalent. The 93LC76-I/SN carries verified programmability certification from DiGi-Electronics, while the 93LC76C-I/SN does not carry this specific verification status.

Frequently Asked Questions (FAQ)

Q: Can the 93LC76C-I/SN replace the 93LC76-I/SN in all applications?

A: The 93LC76C-I/SN is functionally equivalent for applications where the supply voltage does not exceed 5.5V. If your circuit operates at voltages between 5.5V and 6.0V, the 93LC76-I/SN is required.

Q: Are the package dimensions identical between these parts?

A: Yes. Both parts use the 8-SOIC package with 0.154" width and 3.90mm dimensions, ensuring identical PCB footprint and mounting compatibility.

Q: What is the significance of the programmability verification status?

A: The 93LC76-I/SN carries verified programmability certification from DiGi-Electronics, indicating confirmed compatibility with standard programming equipment and procedures. The 93LC76C-I/SN does not carry this specific verification status.

Q: Do both parts support the same Microwire interface protocol?

A: Yes. Both the 93LC76-I/SN and 93LC76C-I/SN operate at 3 MHz Microwire serial interface with identical timing specifications and memory organization.

Q: Are there any compliance differences between these parts?

A: No. Both parts maintain identical ROHS3 compliance and REACH unaffected status, with matching moisture sensitivity level (MSL) of 1 (Unlimited).
