25LC160C-E/ST EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 25LC160C-E/ST is a 16Kbit Serial Peripheral Interface (SPI) EEPROM memory IC manufactured by Microchip Technology in an 8-TSSOP surface mount package. This non-volatile memory device operates at 10 MHz clock frequency with a 5ms write cycle time and supports supply voltages from 2.5V to 5.5V across an operating temperature range of -40°C to 125°C. The part is ROHS3 compliant and currently in active production status with 796 units in stock. Equivalent and substitute parts are identified based on matching memory capacity, interface protocol, package type, and electrical operating parameters to ensure direct functional replacement in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 25LC160C-E/ST are qualified based on the following critical parameters:

• Memory Capacity: 16Kbit (2K x 8 organization) — all substitutes must match this capacity
• Interface Protocol: SPI — all substitutes must use SPI interface
• Package: 8-TSSOP surface mount — all substitutes must use identical package footprint
• Write Cycle Time: 5ms — all substitutes must support this specification
• Supply Voltage Range: Minimum 2.5V support required for direct substitution
• Operating Temperature: Minimum -40°C to 125°C range required for direct substitution
• Compliance: ROHS3 compliance required

Substitutes are grouped into two categories:

Direct Substitutes (Identical Specifications): Parts meeting all critical parameters without derating or design modification.

Compatible Substitutes (Enhanced Specifications): Parts exceeding the 25LC160C-E/ST specifications in clock frequency or supply voltage range while maintaining backward compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Direct Substitute: 25LC160A-E/ST (Microchip Technology) — Identical electrical specifications and operating parameters to the 25LC160C-E/ST. Same manufacturer ensures design continuity and documentation compatibility. 898 units available in stock.

Enhanced Specification Substitute with Full Temperature Range: CAV25160YE-GT3 (onsemi) — Maintains the -40°C to 125°C operating temperature range required by the original part. Offers 20 MHz clock frequency capability. AEC-Q100 automotive qualification available. 1552 units in stock.

High-Volume Substitute: M95160-RDW6TP (STMicroelectronics) — Matches 10 MHz clock frequency specification. Largest inventory availability at 53,400 units. Operating temperature limited to -40°C to 85°C; suitable for applications not requiring the full 125°C upper limit. Cut Tape & Digi-Reel packaging available.

Lower Clock Frequency Alternatives: R1EX25016ATA00I#S0 (Renesas) and S-25C160A0I-T8T1U3 (ABLIC) operate at 5 MHz, half the original specification. These are suitable only for applications with reduced SPI clock speed requirements and lower operating temperature ceiling (-40°C to 85°C).

All recommended substitutes maintain ROHS3 compliance, 16Kbit capacity, 2K x 8 organization, SPI interface, 5ms write cycle time, and 8-TSSOP package footprint.

Frequently Asked Questions (FAQ)

Q: Can I use CAT25160YI-GT3 as a direct replacement for 25LC160C-E/ST?

A: CAT25160YI-GT3 is functionally compatible but with operating temperature limitations. The onsemi part operates from -40°C to 85°C, while the original 25LC160C-E/ST operates to 125°C. If your application requires the full 125°C upper temperature range, use CAV25160YE-GT3 instead. CAT25160YI-GT3 is suitable for standard industrial temperature range applications.

Q: What is the difference between M95160-DFDW6TP and M95160-RDW6TP?

A: Both are STMicroelectronics M95160 variants in 8-TSSOP package. M95160-DFDW6TP operates at 20 MHz with -40°C to 85°C temperature range. M95160-RDW6TP operates at 10 MHz (matching the original part) with -40°C to 85°C temperature range. Select M95160-RDW6TP for clock frequency compatibility with the 25LC160C-E/ST.

Q: Are there supply voltage compatibility concerns with substitute parts?

A: The original 25LC160C-E/ST requires minimum 2.5V supply. Most substitutes support lower minimum voltages (1.6V to 1.8V), making them backward compatible. Verify your circuit supplies at least 2.5V if using parts with lower minimum voltage ratings. All substitutes support the 5.5V maximum.

Q: Can I use R1EX25016ATA00I#S0 or S-25C160A0I-T8T1U3 in place of the original part?

A: These parts operate at 5 MHz, half the original 10 MHz specification. They are suitable only if your application does not require 10 MHz SPI clock speed. Both are limited to -40°C to 85°C operating temperature. Use only if your design specifications permit reduced clock frequency and lower temperature ceiling.

Q: Does packaging type (Tube vs. Tape & Reel) affect electrical compatibility?

A: No. Packaging type affects only handling, storage, and assembly processes. Tube, Tape & Reel, and Cut Tape packaging contain electrically identical components. Select packaging based on your manufacturing process requirements, not electrical performance.

Q: Is CAV25160YE-GT3 suitable for automotive applications?

A: CAV25160YE-GT3 carries AEC-Q100 automotive qualification. If your application requires automotive-grade components, this part meets that requirement. The original 25LC160C-E/ST does not carry automotive qualification.
