Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 25AA080D-I/P are qualified based on strict equivalence across all critical electrical and mechanical parameters. The substitution criteria are:

• Memory capacity and organization (8Kbit, 1K x 8 configuration)
• Serial Peripheral Interface (SPI) protocol
• Operating frequency (10 MHz maximum)
• Supply voltage compatibility (1.8V ~ 5.5V)
• Temperature range (-40°C ~ 85°C)
• Physical package (8-DIP through-hole)
• Write cycle performance (5ms)
• Compliance certifications (ROHS3, REACH Unaffected)

The identified substitutes 25AA080A-I/P and 25AA080B-I/P meet all these parameters and represent manufacturing variants within the same product family from Microchip Technology.

Parameter Comparison

Engineering Selection Recommendations

All three parts—25AA080D-I/P, 25AA080A-I/P, and 25AA080B-I/P—are functionally equivalent and maintain active product status from Microchip Technology. Selection between these parts should be based on availability and supply chain requirements rather than technical performance differences. All parts carry identical ROHS3 compliance and REACH Unaffected status, making them suitable for applications with environmental and regulatory compliance requirements. The 25AA080A-I/P and 25AA080B-I/P variants show higher current inventory levels (1378 and 1331 units respectively) compared to the 25AA080D-I/P (786 units), which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can 25AA080A-I/P or 25AA080B-I/P be used as direct replacements for 25AA080D-I/P?

A: Yes. All three parts share identical electrical specifications, memory capacity, SPI interface, operating voltage range, temperature range, and 8-DIP package configuration. They are direct functional equivalents.

Q: Are there any differences in programming or protocol between these parts?

A: No. All parts implement the same SPI protocol with 10 MHz maximum frequency and 5ms write cycle time. No firmware or software modifications are required when substituting between these parts.

Q: Do all parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH Unaffected, and carry MSL rating 1 (Unlimited). They meet identical environmental and regulatory requirements.

Q: Is the 8-DIP package identical across all three parts?

A: Yes. All parts use the same 8-DIP (0.300", 7.62mm) through-hole package with identical pin configuration and PCB footprint.

Q: What is the difference between the 25AA080D, 25AA080A, and 25AA080B variants?

A: These designations represent manufacturing variants within the same product family. The letters (D, A, B) indicate different production batches or revisions, but all maintain identical electrical and mechanical specifications.
