Key Parameters

Substitute Part Grouping Explanation

The 25AA010AT-I/MC qualifies as a direct substitute for the 25LC010AT-I/MC based on the following critical parameters:

Matching Parameters:

• Memory capacity: 1Kbit
• Memory organization: 128 x 8
• Interface protocol: SPI
• Clock frequency: 10 MHz
• Write cycle time: 5ms
• Package type: 8-VFDFN Exposed Pad (2x3)
• Operating temperature range: -40°C ~ 85°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Voltage Supply Difference: The 25AA010AT-I/MC operates across 1.8V ~ 5.5V, providing extended low-voltage capability compared to the 25LC010AT-I/MC (2.5V ~ 5.5V). This expanded voltage range maintains full compatibility with applications using the original part's 2.5V ~ 5.5V specification.

Parameter Comparison

Engineering Selection Recommendations

Both the 25LC010AT-I/MC and 25AA010AT-I/MC are active production components from Microchip Technology with identical RoHS3 compliance and REACH unaffected status. The 25AA010AT-I/MC provides extended voltage range capability (1.8V minimum versus 2.5V minimum) while maintaining all other electrical and mechanical specifications. Selection between these parts should be based on supply chain availability and voltage requirement compatibility with the target application. The 25AA010AT-I/MC currently maintains higher inventory availability (7019 units) compared to the 25LC010AT-I/MC (3100 units).

Frequently Asked Questions (FAQ)

Q: Can the 25AA010AT-I/MC replace the 25LC010AT-I/MC in existing designs?
