25LC160/P EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 25LC160/P is a 16Kbit Serial Peripheral Interface (SPI) EEPROM memory integrated circuit manufactured by Microchip Technology. This non-volatile memory device operates at 2 MHz clock frequency with a 2K x 8 memory organization and is housed in an 8-DIP through-hole package. The part is actively produced and ROHS3 compliant, making it suitable for embedded systems requiring persistent data storage with SPI interface compatibility. Substitute parts are identified when equivalent electrical and mechanical parameters allow direct functional replacement while maintaining system compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 25LC160/P are qualified based on the following criteria:

Core Electrical Parameters (Must Match):

• Memory Type: Non-Volatile EEPROM
• Memory Size: 16Kbit
• Memory Organization: 2K x 8
• Memory Interface: SPI
• Supply Voltage Range: 2.5V ~ 5.5V
• Write Cycle Time: 5ms
• Package Type: 8-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole

Allowable Variations:

• Clock Frequency: May be equal to or greater than 2 MHz (backward compatible)
• Operating Temperature: May be extended beyond 0°C ~ 70°C (wider range acceptable)
• Product Status: Must be Active
• Compliance: ROHS3 and REACH status must match

The 25LC160/P operates at 2 MHz. Substitute parts operating at higher clock frequencies (10 MHz) are functionally compatible as they maintain backward compatibility with 2 MHz operation. Extended operating temperature ranges provide additional design margin and are acceptable substitutes.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (25LC160-I/P, 25LC160C-I/P, 25LC160D-I/P) meet the core electrical and mechanical requirements for direct replacement of the 25LC160/P in applications requiring 16Kbit SPI EEPROM functionality.

25LC160-I/P: Maintains identical 2 MHz clock frequency specification while extending the operating temperature range to -40°C ~ 85°C. This part provides equivalent performance with enhanced temperature margin and is suitable for applications requiring extended environmental operating conditions.

25LC160C-I/P and 25LC160D-I/P: Both operate at 10 MHz clock frequency, providing higher data throughput capability while maintaining full backward compatibility with 2 MHz SPI bus operation. The extended operating temperature range (-40°C ~ 85°C) offers additional design margin. The 25LC160D-I/P variant has the highest current inventory availability (6074 Pcs).

All substitute parts maintain ROHS3 compliance and active product status. Selection should be based on application-specific requirements for clock frequency performance and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the 25LC160C-I/P or 25LC160D-I/P (10 MHz) be used as direct replacements for the 25LC160/P (2 MHz)?

A: Yes. The 10 MHz variants are backward compatible with 2 MHz SPI bus operation. Higher clock frequency capability does not prevent operation at lower frequencies. Pin configuration, memory organization, and electrical interface remain identical.

Q: What is the difference between 25LC160-I/P, 25LC160C-I/P, and 25LC160D-I/P?

A: The primary differences are clock frequency and operating temperature range. The 25LC160-I/P maintains 2 MHz operation. The 25LC160C-I/P and 25LC160D-I/P both operate at 10 MHz. All three extend the operating temperature range to -40°C ~ 85°C compared to the original 25LC160/P specification of 0°C ~ 70°C.

Q: Are all substitute parts in the same 8-DIP package?

A: Yes. All parts use the 8-DIP (0.300", 7.62mm) through-hole package with identical pinout and mechanical dimensions, enabling direct socket replacement without PCB modification.

Q: Do the substitute parts maintain the same supply voltage range?

A: Yes. All substitute parts operate across the 2.5V ~ 5.5V supply voltage range, identical to the 25LC160/P specification.

Q: What is the write cycle time for all these parts?

A: The write cycle time is 5ms for the 25LC160/P and all substitute parts, ensuring equivalent data write performance.
