Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 11LC161-I/P are qualified based on strict equivalence across the following critical parameters:

• Memory capacity: 16Kbit
• Memory organization: 2K x 8
• Interface type: Single Wire
• Clock frequency: 100 kHz
• Write cycle time: 5ms
• Package configuration: 8-DIP through-hole
• Operating temperature range: -40°C to 85°C
• RoHS3 compliance status
• MSL rating: 1 (Unlimited)

The 11AA160-I/P and 11LC160-I/P meet all functional and mechanical substitution criteria. Both devices are manufactured by Microchip Technology, maintain Active product status, and are certified to the same environmental and compliance standards. The primary distinction between substitute options relates to minimum supply voltage specification, which does not restrict substitution applicability for designs operating within the 2.5V to 5.5V range.

Parameter Comparison

Engineering Selection Recommendations

All three parts—11LC161-I/P, 11AA160-I/P, and 11LC160-I/P—are qualified as direct functional equivalents for 16Kbit single-wire EEPROM applications. Selection among these parts is determined by supply voltage requirements and inventory availability:

For designs operating at supply voltages of 2.5V or higher, the 11LC161-I/P and 11LC160-I/P are functionally identical and interchangeable. The 11AA160-I/P extends compatibility to lower voltage applications, supporting operation down to 1.8V while maintaining all other electrical and mechanical specifications.

All substitute parts maintain Active product status, ROHS3 compliance, and unlimited moisture sensitivity level rating, ensuring equivalent reliability and regulatory standing across design lifecycles.

Frequently Asked Questions (FAQ)

Q: Can the 11AA160-I/P replace the 11LC161-I/P in existing designs?

A: Yes. The 11AA160-I/P is functionally equivalent across all critical parameters including memory capacity, organization, interface type, clock frequency, write cycle time, package configuration, and operating temperature range. The extended lower voltage specification (1.8V minimum) of the 11AA160-I/P does not restrict its use in designs operating within the 2.5V to 5.5V range.

Q: What is the primary difference between the substitute parts?

A: The 11AA160-I/P supports a minimum supply voltage of 1.8V, while both the 11LC161-I/P and 11LC160-I/P specify a 2.5V minimum. For applications requiring operation below 2.5V, the 11AA160-I/P is the appropriate selection. All other electrical and mechanical characteristics are identical.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 8-DIP (0.300", 7.62mm) through-hole package configuration with identical pin assignments for single-wire EEPROM interface operation.

Q: Do substitute parts carry the same compliance certifications?

A: Yes. All three parts are RoHS3 compliant, carry MSL rating 1 (Unlimited), and maintain Active product status with equivalent regulatory standing.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes, provided the circuit design operates within the supply voltage range supported by the selected part. For designs operating at 2.5V or higher, all three parts are directly interchangeable without circuit modification.
