Key Parameters

Substitute Part Grouping Explanation

Substitution of the AT25010-10PC is determined by the following critical parameters:

• Memory Capacity: 1Kbit with 128 x 8 organization
• Interface Protocol: SPI serial communication
• Package Compatibility: 8-DIP through-hole form factor with 0.300" (7.62mm) pitch
• Functional Equivalence: Non-volatile EEPROM technology

The substitute part 25AA010A-I/P meets these core requirements while offering enhanced electrical characteristics. Both devices share identical memory organization, SPI interface, package footprint, and write cycle timing. The substitute operates at a higher clock frequency (10 MHz versus 3 MHz) and supports an extended supply voltage range (1.8V ~ 5.5V versus 4.5V ~ 5.5V), making it suitable for direct replacement in existing designs.

Parameter Comparison

Engineering Selection Recommendations

The 25AA010A-I/P is a direct functional substitute for the AT25010-10PC based on the following engineering criteria:

Electrical Compatibility: Both devices implement identical SPI protocol and memory organization. The substitute's higher clock frequency (10 MHz) is backward-compatible with systems designed for 3 MHz operation. The extended supply voltage range of the substitute (1.8V ~ 5.5V) encompasses the original part's operating range (4.5V ~ 5.5V).

Mechanical Compatibility: Identical 8-DIP package footprint and through-hole mounting configuration ensure direct PCB compatibility without layout modifications.

Product Status: The substitute part is classified as active with current manufacturing availability, addressing the obsolescence of the original AT25010-10PC.

Compliance: The 25AA010A-I/P meets ROHS3 compliance requirements, whereas the original part is RoHS non-compliant. Both parts are REACH unaffected and carry EAR99 ECCN classification.

Frequently Asked Questions (FAQ)

Q: Can the 25AA010A-I/P directly replace the AT25010-10PC in existing designs?

A: Yes. Both devices share identical memory capacity (1Kbit), organization (128 x 8), SPI interface, package footprint (8-DIP), and write cycle timing (5ms). The substitute operates at higher clock frequency and lower minimum supply voltage, both of which are backward-compatible with designs specified for the original part.

Q: What is the difference in clock frequency between these parts?

A: The AT25010-10PC operates at 3 MHz, while the 25AA010A-I/P operates at 10 MHz. Systems designed for 3 MHz operation function correctly with the higher-frequency substitute, as the substitute supports all lower clock speeds.

Q: Are there supply voltage considerations for substitution?

A: The original part requires 4.5V ~ 5.5V supply voltage. The substitute accepts 1.8V ~ 5.5V. If your system operates within the original 4.5V ~ 5.5V range, the substitute is fully compatible. Systems operating at lower voltages (1.8V ~ 4.5V) can only use the substitute.

Q: Does the package footprint remain identical?

A: Yes. Both parts use 8-DIP packaging with 0.300" (7.62mm) pitch. No PCB layout modifications are required for substitution.

Q: What is the significance of the product status difference?

A: The AT25010-10PC is obsolete and no longer manufactured. The 25AA010A-I/P is active with current production availability, ensuring long-term supply chain reliability for new designs and legacy system support.
