Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 24LC65/P is determined by strict equivalence across the following critical parameters: memory capacity (64Kbit), memory organization (8K x 8 byte structure), serial communication protocol (I2C), clock frequency (400 kHz), access time (900 ns), write cycle time (5 ms), supply voltage compatibility (2.5V ~ 6.0V minimum), physical package format (8-DIP through-hole), and regulatory compliance (RoHS3). The 24LC65-I/P meets all these criteria and is classified as a manufacturer-recommended equivalent part. Both devices share identical base product designation (24LC65) and maintain full functional and electrical interchangeability within specified operating conditions.

Parameter Comparison

Engineering Selection Recommendations

The 24LC65-I/P is a direct manufacturer-recommended substitute for the 24LC65/P. Both parts maintain identical electrical performance specifications, memory architecture, and physical packaging. The 24LC65-I/P provides an extended operating temperature range (-40°C to 85°C versus 0°C to 70°C), which represents an enhancement for applications requiring operation in wider environmental conditions. Both devices carry active product status, verified programmability certification, and full RoHS3 and REACH compliance. Selection between these parts should be based on application temperature requirements and component availability.

Frequently Asked Questions (FAQ)

Q: Can the 24LC65-I/P replace the 24LC65/P in existing designs? A: Yes. The 24LC65-I/P is electrically and mechanically equivalent to the 24LC65/P across all critical parameters including memory capacity, I2C interface, clock frequency, access time, supply voltage range, and 8-DIP package format. Direct substitution is supported without circuit modification.

Q: What is the difference between these two part numbers? A: The primary difference is the operating temperature range. The 24LC65/P operates from 0°C to 70°C, while the 24LC65-I/P operates from -40°C to 85°C. All other electrical and physical specifications are identical.

Q: Are both parts RoHS3 compliant? A: Yes. Both the 24LC65/P and 24LC65-I/P are ROHS3 compliant with moisture sensitivity level 1 (unlimited) and REACH unaffected status.

Q: Do these parts require different PCB layouts or soldering procedures? A: No. Both devices use identical 8-DIP through-hole packaging (0.300", 7.62mm). PCB layouts, pin assignments, and soldering procedures are identical.

Q: Which part should I select for new designs? A: Selection depends on application temperature requirements. For standard industrial applications (0°C to 70°C), either part is suitable. For extended temperature range applications (-40°C to 85°C), the 24LC65-I/P is the appropriate choice.
