Substitute Part Grouping Explanation

Substitution eligibility for the 24AA014-I/P is determined by strict equivalence across the following critical parameters:

• Memory capacity: 1Kbit with 128 x 8 organization
• Interface protocol: I2C at 400 kHz operation
• Supply voltage range: 1.7V ~ 5.5V minimum compatibility
• Package format: 8-DIP through-hole mounting
• Temperature rating: -40°C ~ 85°C operational range
• Compliance certifications: ROHS3 and REACH status

The 24AA01-I/P meets all substitution criteria as a functionally equivalent alternative, maintaining identical memory capacity, interface specification, voltage range, package configuration, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 24AA014-I/P and 24AA01-I/P are active production components from Microchip Technology with identical ROHS3 and REACH compliance certifications. Selection between these parts is based on access time requirements: the 24AA014-I/P provides 900 ns access time, while the 24AA01-I/P operates at 3500 ns access time. Both devices maintain equivalent electrical specifications for supply voltage, operating temperature range, and I2C interface operation. Circuit designs requiring faster memory access should specify the 24AA014-I/P; applications with relaxed timing constraints may utilize the 24AA01-I/P as a direct functional replacement.

Frequently Asked Questions (FAQ)

Q: Can the 24AA01-I/P directly replace the 24AA014-I/P in existing circuit designs?

A: Yes, the 24AA01-I/P is electrically and mechanically compatible for direct substitution. Both devices share identical memory capacity, I2C interface specification, voltage supply range, and 8-DIP package configuration. The primary difference is access time performance.

Q: What is the significance of the access time difference between these parts?

A: Access time specifies the delay from address input to valid data output. The 24AA014-I/P provides 900 ns access time, while the 24AA01-I/P operates at 3500 ns. Applications with strict timing requirements must verify that the slower access time of the 24AA01-I/P does not violate system timing constraints.

Q: Are both parts available in the same package configuration?

A: Yes, both the 24AA014-I/P and 24AA01-I/P are supplied in 8-DIP (0.300", 7.62mm) through-hole packages with identical pinout and mechanical dimensions.

Q: Do these parts have equivalent compliance certifications?

A: Both parts are ROHS3 compliant and REACH unaffected, meeting identical environmental and regulatory requirements.

Q: What inventory availability exists for these substitute parts?

A: The 24AA014-I/P has 1009 pieces in stock, while the 24AA01-I/P has 2435 pieces available.
