11AA020T-I/TT EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 11AA020T-I/TT is a 2Kbit Single Wire EEPROM memory IC manufactured by Microchip Technology in SOT-23-3 surface mount packaging. This non-volatile memory device operates at 100 kHz clock frequency with a supply voltage range of 1.8V to 5.5V and supports a write cycle time of 5ms per word or page. The device is currently in active product status and ROHS3 compliant. Substitute parts are identified when equivalent electrical specifications, memory capacity, interface protocol, and physical packaging are maintained across the product line.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 11AA020T-I/TT are identified based on strict equivalence across the following critical parameters:

• Memory capacity: 2Kbit (256 x 8 organization)
• Interface type: Single Wire protocol at 100 kHz
• Electrical performance: 5ms write cycle time, 1.8V to 5.5V supply voltage
• Physical form factor: SOT-23-3 surface mount package
• Environmental compliance: ROHS3 compliant, MSL 1 rating
• Operating temperature range: -40°C to 85°C

The 11AA02UIDT-I/TT meets all substitution criteria as a direct equivalent within the Microchip Technology 11AA02 base product family.

Parameter Comparison

Engineering Selection Recommendations

Both the 11AA020T-I/TT and 11AA02UIDT-I/TT are active products from Microchip Technology with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability, lead time, or procurement requirements. Both devices maintain ROHS3 compliance and MSL 1 moisture sensitivity rating, suitable for standard surface mount assembly processes. The 11AA02UIDT-I/TT variant currently maintains higher inventory levels (10,300 pcs vs. 4,400 pcs), which may influence supply chain decisions.

Frequently Asked Questions (FAQ)

Q: Can the 11AA02UIDT-I/TT be used as a direct replacement for the 11AA020T-I/TT?

A: Yes. Both parts are electrically and mechanically equivalent with identical memory capacity (2Kbit), interface protocol (Single Wire at 100 kHz), supply voltage range (1.8V to 5.5V), write cycle time (5ms), and SOT-23-3 packaging. Pin configuration and functional behavior are identical.

Q: Are there any differences in the package or pinout between these parts?

A: No. Both parts use the SOT-23-3 (TO-236-3, SC-59) surface mount package with identical pinout and mechanical dimensions.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 11AA020T-I/TT and 11AA02UIDT-I/TT are ROHS3 compliant with MSL 1 moisture sensitivity rating and REACH unaffected status.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the temperature range of -40°C to 85°C (TA), suitable for industrial and commercial applications.

Q: Are there any restrictions on substituting between these parts in existing designs?

A: No restrictions exist based on the provided electrical and mechanical parameters. Both parts are functionally interchangeable within the specified operating conditions.
