93LC76CT-I/MS EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 93LC76CT-I/MS is an 8Kbit EEPROM memory integrated circuit manufactured by Microchip Technology, designed for non-volatile data storage applications requiring Microwire serial interface communication. This device operates across a wide supply voltage range of 2.5V to 5.5V and maintains functionality across industrial temperature ranges from -40°C to 85°C. The component is currently in active production status with robust inventory availability. Alternative part numbers may be required due to packaging format preferences, compliance certifications, or supply chain considerations while maintaining identical electrical and mechanical functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 93LC76CT-I/MS is determined by strict alignment across the following critical parameters: memory capacity (8Kbit), memory organization (1K x 8 or 512 x 16 configuration), serial interface protocol (Microwire), clock frequency (3 MHz), write cycle timing (5ms), supply voltage compatibility (2.5V to 5.5V), operating temperature range (-40°C to 85°C), and physical package format (8-MSOP surface mount). The primary distinction between equivalent parts lies in packaging format (Tape & Reel versus Tube) and regulatory compliance certifications. All substitute parts must maintain identical electrical performance characteristics and pin-compatible surface mount packaging to ensure direct functional replacement without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

Both the 93LC76CT-I/MS and 93LC76C-I/MS are electrically and mechanically equivalent EEPROM memory devices from Microchip Technology with identical functional specifications. Selection between these parts should be based on specific project requirements regarding regulatory compliance and packaging logistics. The 93LC76CT-I/MS carries RoHS3 compliance certification, making it suitable for applications subject to European Union Restriction of Hazardous Substances regulations. The 93LC76C-I/MS is supplied in Tube packaging format and does not carry RoHS compliance certification. Both devices maintain active production status with adequate inventory availability. Packaging format selection (Tape & Reel versus Tube) depends on assembly process requirements and component handling procedures at the manufacturing facility.

Frequently Asked Questions (FAQ)

Q: Are the 93LC76CT-I/MS and 93LC76C-I/MS pin-compatible? A: Yes. Both devices use identical 8-MSOP surface mount packaging with matching pin configurations, enabling direct substitution on PCB layouts without modification.

Q: What is the primary difference between these two part numbers? A: The primary differences are packaging format (Tape & Reel versus Tube) and RoHS compliance certification status. Electrical and memory specifications are identical.

Q: Can the 93LC76C-I/MS replace the 93LC76CT-I/MS in RoHS-regulated applications? A: No. The 93LC76C-I/MS is RoHS non-compliant. Applications requiring RoHS3 compliance must use the 93LC76CT-I/MS.

Q: Do these parts require different PCB footprints? A: No. Both parts use the 8-MSOP package format with identical physical dimensions (0.118", 3.00mm width), requiring the same PCB footprint design.

Q: What is the significance of the packaging format difference? A: Tape & Reel packaging is optimized for high-volume automated assembly processes, while Tube packaging is suitable for lower-volume manual assembly or component storage applications.

Q: Are the memory specifications identical between these parts? A: Yes. Both devices provide 8Kbit non-volatile EEPROM storage with 1K x 8 or 512 x 16 organization, 3 MHz Microwire interface, and 5ms write cycle time.

Q: What supply voltage range do these devices support? A: Both the 93LC76CT-I/MS and 93LC76C-I/MS operate across 2.5V to 5.5V supply voltage range, providing compatibility with both 3.3V and 5V logic systems.
