Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 11AA161-I/P is determined by strict equivalence across the following critical parameters:

• Memory capacity and organization (16Kbit, 2K x 8 configuration)
• Interface protocol (Single Wire at 100 kHz operation)
• Electrical characteristics (1.8V to 5.5V supply voltage, 5ms write cycle time)
• Physical packaging (8-DIP through-hole form factor)
• Temperature operating range (-40°C to 85°C)
• Compliance certifications (RoHS3, REACH Unaffected, EAR99)

The 11AA160-I/P meets all substitution criteria as a manufacturer-recommended equivalent, maintaining identical electrical specifications, memory organization, interface characteristics, and physical packaging.

Parameter Comparison
