Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 24AA32A/P is determined by the following critical parameters:

• Memory capacity and organization (32Kbit, 4K x 8 configuration)
• I2C interface protocol at 400 kHz operation
• Access time specification (900 ns)
• Physical package format (8-DIP, 0.300" pitch)
• Through-hole mounting compatibility
• RoHS3 compliance certification

The substitute parts 24AA32A-I/P and 24AA32AF-I/P meet these core electrical and mechanical requirements. Both alternatives maintain identical memory specifications, interface characteristics, and package dimensions as the original 24AA32A/P.

Parameter Comparison

Engineering Selection Recommendations

The 24AA32A-I/P is the primary recommended substitute for the obsolete 24AA32A/P. This part maintains full electrical and mechanical compatibility while offering active product status and extended operating temperature range (-40°C to 85°C versus 0°C to 70°C). The 24AA32A-I/P carries verified programmability certification and is available in higher inventory quantities (3300 units).

The 24AA32AF-I/P serves as a secondary alternative with identical core specifications. This part features a marginally lower minimum supply voltage (1.7V versus 1.8V) and active product status. However, programmability verification is not documented for this variant.

Both substitutes are ROHS3 compliant and maintain the same package footprint and through-hole mounting configuration as the original part, enabling direct board-level replacement without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can 24AA32A-I/P directly replace 24AA32A/P in existing designs?

A: Yes. The 24AA32A-I/P maintains identical memory capacity (32Kbit), interface protocol (I2C at 400 kHz), access time (900 ns), and physical package (8-DIP) specifications. The extended operating temperature range (-40°C to 85°C) provides broader environmental compatibility than the original part.

Q: What is the difference between 24AA32A-I/P and 24AA32AF-I/P?

A: Both parts share identical memory specifications and package format. The primary differences are minimum supply voltage (1.8V for 24AA32A-I/P versus 1.7V for 24AA32AF-I/P) and programmability verification status (verified for 24AA32A-I/P, not verified for 24AA32AF-I/P).

Q: Are the substitute parts available in the same packaging as the original?

A: The substitute parts are supplied in tube packaging, whereas the original 24AA32A/P was supplied in bulk. Both alternatives maintain the identical 8-DIP (0.300", 7.62mm) component package format suitable for through-hole PCB assembly.

Q: Do the substitute parts meet RoHS compliance requirements?

A: Yes. Both 24AA32A-I/P and 24AA32AF-I/P are ROHS3 compliant, matching the compliance status of the original 24AA32A/P.

Q: What supply voltage range should be used for these EEPROM parts?

A: The 24AA32A-I/P operates across 1.8V to 5.5V supply range. The 24AA32AF-I/P operates across 1.7V to 5.5V supply range. Both ranges encompass standard logic supply voltages (3.3V, 5V) used in embedded systems and microcontroller applications.
