25LC160CT-E/SN Equivalent & Substitute Parts

Part Overview

The 25LC160CT-E/SN is a 16Kbit SPI EEPROM memory IC manufactured by Microchip Technology, housed in an 8-SOIC package. This non-volatile memory device operates at 10 MHz with a supply voltage range of 2.5V to 5.5V and supports operating temperatures from -40°C to 125°C. The part is ROHS3 compliant and currently in active production status with 2000 units in stock.

Substitute parts are necessary when the original part becomes unavailable, when alternative packaging formats are required, or when enhanced performance specifications (such as higher clock frequency or extended voltage ranges) are needed for system optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 25LC160CT-E/SN is determined by the following critical parameters:

Primary Compatibility Criteria:

• Memory capacity: 16Kbit
• Memory organization: 2K x 8
• Interface protocol: SPI
• Package footprint: 8-SOIC (0.154", 3.90mm Width)
• Mounting type: Surface Mount

Secondary Compatibility Criteria:

• Clock frequency: 10 MHz or higher (backward compatible)
• Supply voltage range: Must encompass or exceed 2.5V ~ 5.5V
• Operating temperature range: Must support -40°C ~ 125°C minimum
• Write cycle time: 5ms or faster

Substitute parts are grouped into two categories based on clock frequency performance: standard 10 MHz devices and enhanced 20 MHz devices. All substitutes maintain identical memory capacity, organization, and SPI interface protocol. Packaging variations (Tape & Reel vs. Cut Tape) do not affect electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Identical Specifications): The 25LC160DT-E/SN is the direct equivalent, differing only in packaging format (Cut Tape & Digi-Reel versus Tape & Reel). This part maintains all electrical and thermal specifications of the original 25LC160CT-E/SN and is suitable for direct substitution in production environments where packaging format flexibility is acceptable.

Enhanced Performance Substitutes (20 MHz Clock Frequency): The AT25160B-SSHL-T, CAT25160VI-GT3, CAV25160VE-GT3, and M95160-DRMN3TP/K offer doubled clock frequency (20 MHz) while maintaining SPI interface compatibility and 16Kbit capacity. These parts are backward compatible with 10 MHz system designs. Selection among these options depends on voltage range requirements and operating temperature specifications:

• AT25160B-SSHL-T and CAT25160VI-GT3 operate at reduced temperature range (-40°C to 85°C) with extended low-voltage support (1.8V minimum).
• CAV25160VE-GT3 maintains the full -40°C to 125°C temperature range with 2.5V minimum voltage, matching the original part's thermal envelope.
• M95160-DRMN3TP/K provides the widest voltage range (1.8V ~ 5.5V) and full temperature range (-40°C ~ 125°C) with AEC-Q100 automotive qualification.

Automotive-Grade Alternatives: The BR25H160F-2CE2 and M95160-DRMN3TP/K carry AEC-Q100 automotive qualification. The BR25H160F-2CE2 maintains 10 MHz operation with improved write cycle time (4ms) and full temperature range support. The M95160-DRMN3TP/K combines automotive qualification with enhanced 20 MHz performance.

Standard Performance Substitute (10 MHz): The M95160-RMN6TP provides 10 MHz operation matching the original part's clock frequency but operates at reduced temperature range (-40°C to 85°C) with 1.8V minimum voltage support.

Frequently Asked Questions (FAQ)

Q: Can I use a 20 MHz substitute part in a system designed for 10 MHz operation? A: Yes. The 20 MHz parts (AT25160B-SSHL-T, CAT25160VI-GT3, CAV25160VE-GT3, M95160-DRMN3TP/K) are backward compatible with 10 MHz system designs. The SPI interface protocol remains identical, and the higher clock frequency does not create incompatibility with slower host controllers.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging? A: Both packaging formats contain identical electronic components. Tape & Reel packaging is supplied on continuous carrier tape suitable for high-volume automated assembly. Cut Tape & Digi-Reel packaging provides smaller quantities on cut tape segments or Digi-Reel format, suitable for lower-volume production or prototyping. The electrical and thermal performance is identical.

Q: Does the 25LC160CT-E/SN support the full -40°C to 125°C temperature range in all substitute parts? A: No. The AT25160B-SSHL-T and CAT25160VI-GT3 operate only to 85°C maximum. For applications requiring the full -40°C to 125°C range, select 25LC160DT-E/SN, BR25H160F-2CE2, CAV25160VE-GT3, or M95160-DRMN3TP/K.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance, matching the environmental certification of the original 25LC160CT-E/SN.

Q: Which substitute offers the best availability? A: The AT25160B-SSHL-T has the highest inventory level at 65,300 units in stock, followed by M95160-DRMN3TP/K at 25,300 units.

Q: Can I substitute the 25LC160CT-E/SN with a part that has a lower voltage supply minimum? A: Yes, provided your system operates within the substitute part's voltage range. Parts with 1.8V minimum (AT25160B-SSHL-T, CAT25160VI-GT3, M95160-DRMN3TP/K, M95160-RMN6TP) are compatible with systems using 2.5V to 5.5V supplies. The lower minimum voltage specification does not restrict operation at higher voltages.

Q: What is the significance of AEC-Q100 qualification? A: AEC-Q100 qualification indicates the part meets automotive industry reliability and quality standards. The BR25H160F-2CE2 and M95160-DRMN3TP/K carry this certification, making them suitable for automotive applications requiring enhanced reliability documentation.
