Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 25LC080A-I/P are qualified based on the following critical parameters that determine functional interchangeability:

• Memory capacity: 8Kbit with 1K x 8 organization
• Interface protocol: SPI at 10 MHz operation
• Package format: 8-DIP through-hole mounting
• Write cycle time: 5ms
• Operating temperature range: -40°C to 85°C
• RoHS3 compliance status

Substitutes are grouped into two categories based on supply voltage specification:

Category 1 (Extended Low-Voltage Operation): Parts with 1.8V minimum supply voltage support broader application environments.

Category 2 (Standard Voltage Operation): Parts with 2.5V minimum supply voltage match the primary part's voltage specification.

All substitute parts maintain identical memory organization, SPI interface, clock frequency, and physical packaging, ensuring pin-compatible replacement without circuit modification.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Verified Compatibility):

The 25LC080B-I/P and 25LC080D-I/P are direct substitutes within the 25LC080 series, maintaining identical voltage specifications (2.5V ~ 5.5V) as the 25LC080A-I/P. The 25LC080B-I/P carries verified programmability certification. The 25LC080D-I/P is in active production status but does not carry programmability verification.

Extended-Range Substitutes (Lower Voltage Capability):

The 25AA080A-I/P and 25AA080B-I/P operate at reduced minimum supply voltage (1.8V) while maintaining all other electrical and physical specifications. Both parts carry verified programmability certification and are suitable for applications requiring extended low-voltage operation. These parts are functionally compatible with 25LC080A-I/P in circuits operating at 2.5V or higher.

Compliance Status:

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and identical ECCN and HTSUS classifications as the primary part.

Frequently Asked Questions (FAQ)

Q: Can 25AA080A-I/P or 25AA080B-I/P replace 25LC080A-I/P in existing designs?

A: Yes, provided the circuit supply voltage operates at 2.5V or higher. The 25AA080 series supports lower minimum voltage (1.8V) but is fully compatible at standard operating voltages. All electrical parameters, memory organization, SPI interface, and physical packaging are identical.

Q: What is the difference between 25LC080A-I/P and 25LC080B-I/P?

A: Both parts share identical electrical specifications, memory capacity, interface protocol, and packaging. The primary distinction is the revision level within the 25LC080 series. Both maintain 2.5V ~ 5.5V supply voltage range and verified programmability status.

Q: Is 25LC080D-I/P a suitable replacement for 25LC080A-I/P?

A: The 25LC080D-I/P is electrically and physically compatible with identical specifications. However, it does not carry verified programmability certification from DiGi-Electronics, unlike the 25LC080A-I/P. Selection should consider application requirements for programmability verification.

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

A: Yes. All listed substitute parts use identical 8-DIP (0.300", 7.62mm) through-hole packaging, enabling direct board-level replacement without layout modification.

Q: What supply voltage range applies to all substitute parts?

A: The 25LC080 series (25LC080A, 25LC080B, 25LC080D) operates at 2.5V ~ 5.5V. The 25AA080 series (25AA080A, 25AA080B) operates at 1.8V ~ 5.5V. All parts function correctly at standard 3.3V and 5V supply levels.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. All listed substitute parts carry ROHS3 compliance certification and REACH unaffected status, matching the primary part's regulatory compliance profile.
