Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 25C160/P are qualified based on the following criteria:

Fixed Parameters (Must Match):

• Memory Size: 16Kbit
• Memory Organization: 2K x 8
• Memory Interface: SPI
• Package / Case: 8-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• Write Cycle Time: 5ms
• RoHS Status: ROHS3 Compliant

Variable Parameters (Allowed to Differ):

• Clock Frequency: 2 MHz to 10 MHz
• Voltage Supply Range: 2.5V ~ 5.5V (encompasses 4.5V ~ 5.5V)
• Operating Temperature Range: -40°C ~ 85°C (encompasses 0°C ~ 70°C)

The three qualified substitutes (25LC160-I/P, 25LC160C-I/P, 25LC160D-I/P) maintain identical memory architecture and physical form factor while offering enhanced operational flexibility through wider voltage and temperature ranges and higher clock frequencies.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain Active product status and full ROHS3 compliance, qualifying them for direct substitution in applications where the 25C160/P is specified.

25LC160-I/P operates at 2 MHz clock frequency with expanded voltage (2.5V ~ 5.5V) and temperature (-40°C ~ 85°C) ranges. This part is suitable for applications requiring lower clock speeds with enhanced environmental tolerance.

25LC160C-I/P and 25LC160D-I/P both operate at 10 MHz clock frequency with identical voltage and temperature specifications. The 25LC160D-I/P maintains higher inventory availability (6074 units) compared to 25LC160C-I/P (1553 units). Both are suitable for applications requiring higher data transfer rates within the same environmental operating window.

Selection between substitutes depends on clock frequency requirements: 2 MHz for 25LC160-I/P or 10 MHz for 25LC160C-I/P and 25LC160D-I/P variants.

Frequently Asked Questions (FAQ)

Q: Can 25LC160-I/P replace 25C160/P in all applications?

A: Yes, provided the application does not require clock frequencies exceeding 2 MHz. The 25LC160-I/P offers superior voltage and temperature range coverage, making it compatible with a broader range of system designs.

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

A: Both parts are electrically identical with 10 MHz clock frequency and matching voltage/temperature specifications. The distinction is inventory availability, with 25LC160D-I/P offering higher stock levels.

Q: Are all substitute parts pin-compatible with 25C160/P?

A: Yes. All parts use identical 8-DIP (0.300", 7.62mm) through-hole packaging with matching pin configuration and SPI interface protocol.

Q: Does substituting to a higher clock frequency part affect system compatibility?

A: No. Parts rated for higher clock frequencies (10 MHz variants) operate at lower frequencies without functional degradation. System clock speed is determined by the host controller, not the memory device maximum rating.

Q: What compliance certifications apply to all substitute parts?

A: All parts maintain ROHS3 compliance, REACH Unaffected status, and unlimited moisture sensitivity rating (MSL 1), matching the original 25C160/P specifications.
