AT25160-10PI Equivalent & Substitute Parts

Part Overview

The AT25160-10PI is a 16Kbit EEPROM memory IC with SPI interface manufactured by Microchip Technology. This device is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing system support and new designs. The part operates at 3 MHz clock frequency with 4.5V to 5.5V supply voltage and is housed in an 8-DIP through-hole package. Due to its obsolete status, equivalent substitute parts with compatible electrical and mechanical specifications are required for procurement and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AT25160-10PI is determined by the following critical parameters:

• Memory Capacity & Organization: Must be 16Kbit with 2K x 8 organization to maintain software compatibility and address space equivalence
• Interface Protocol: SPI interface is mandatory for direct pin and protocol compatibility
• Package & Mounting: 8-DIP through-hole package with 0.300" (7.62mm) spacing ensures mechanical and electrical socket compatibility
• Supply Voltage Compatibility: The substitute must operate within or encompass the 4.5V ~ 5.5V range of the original part
• Operating Temperature Range: Must support -40°C ~ 85°C minimum to maintain thermal specification equivalence

The 25AA160A-I/P meets all substitution criteria. While it offers enhanced specifications (10 MHz clock frequency and extended voltage range of 1.8V ~ 5.5V), these represent improvements that do not compromise backward compatibility with AT25160-10PI applications.

Parameter Comparison

Engineering Selection Recommendations

The 25AA160A-I/P is the direct functional equivalent for AT25160-10PI replacement. Selection is based on the following engineering factors:

• Product Status: The AT25160-10PI is obsolete, while the 25AA160A-I/P maintains active production status, ensuring long-term availability and supply chain continuity
• Compliance: The 25AA160A-I/P is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for new designs and procurement
• Electrical Compatibility: The substitute operates within the original part's voltage and temperature specifications, with enhanced performance margins (higher clock frequency and lower voltage floor)
• Package Compatibility: Identical 8-DIP through-hole package ensures direct socket substitution without PCB redesign

Frequently Asked Questions (FAQ)

Q: Can the 25AA160A-I/P directly replace the AT25160-10PI in existing designs?

A: Yes. Both parts share identical memory capacity (16Kbit), organization (2K x 8), SPI interface, package type (8-DIP), and operating temperature range (-40°C ~ 85°C). The substitute operates within the original part's 4.5V ~ 5.5V supply range and maintains the same 5ms write cycle time.

Q: What are the key differences between these parts?

A: The 25AA160A-I/P offers enhanced specifications: 10 MHz clock frequency (versus 3 MHz) and extended supply voltage range (1.8V ~ 5.5V versus 4.5V ~ 5.5V). These represent performance improvements that do not affect backward compatibility.

Q: Are there any compliance differences?

A: Yes. The AT25160-10PI is RoHS non-compliant, while the 25AA160A-I/P is ROHS3 compliant. For new designs and regulated applications, the 25AA160A-I/P is the appropriate selection.

Q: Will the substitute work in the same PCB footprint?

A: Yes. Both parts use the 8-DIP package with 0.300" (7.62mm) spacing and through-hole mounting, enabling direct PCB compatibility without layout modifications.

Q: Is the 25AA160A-I/P available in the same packaging format?

A: The 25AA160A-I/P is supplied in tube packaging, while the AT25160-10PI packaging format is not specified in the provided data. Both use identical 8-PDIP device packages suitable for through-hole assembly.
