Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following core parameters:

• Memory Size: 1Kbit (128 x 8 organization)
• Memory Interface: SPI
• Package / Case: 8-SOIC form factor (0.154", 3.90mm Width) or compatible 8-SOP
• Mounting Type: Surface Mount
• Write Cycle Time: 5ms or faster

All substitute parts maintain 1Kbit capacity with SPI interface and surface mount 8-pin packaging. Substitute parts exceed the original 3 MHz clock frequency specification, providing backward compatibility with higher performance margins. Voltage supply ranges and operating temperature ranges in substitute parts are equal to or exceed the original part specifications, ensuring functional compatibility in existing circuit designs.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are active products with ROHS3 compliance, addressing the obsolete status and RoHS non-compliance of the AT25010N-10SC. Selection among substitute parts depends on application requirements:

For general industrial applications requiring extended temperature range and higher clock frequency performance, the 25AA010A-I/SN from Microchip Technology provides direct manufacturer continuity with 10 MHz operation and -40°C to 85°C temperature range.

For automotive applications requiring AEC-Q100 qualification, BR25H010F-2CE2 from Rohm Semiconductor or CAV25010VE-GT3 from onsemi are appropriate selections. The BR25H010F-2CE2 offers the fastest write cycle time at 4ms with extended temperature range to 125°C. The CAV25010VE-GT3 maintains the original 8-SOIC package footprint with identical 3.90mm width.

For applications requiring the highest clock frequency and lowest supply voltage floor, the M95010 series from STMicroelectronics operates at 20 MHz with supply voltage down to 1.8V (M95010-RMN6TP) or 2.5V (M95010-WMN6P and M95010-WMN6TP). The M95010-WMN6TP variant offers the largest inventory availability at 40,291 pieces.

Frequently Asked Questions (FAQ)

Q: Can the AT25010N-10SC be directly replaced with any of these substitute parts?

A: Yes, all listed substitute parts maintain functional compatibility through identical 1Kbit capacity, SPI interface, and 8-pin surface mount packaging. The substitute parts exceed the original 3 MHz clock frequency specification, ensuring backward compatibility. Voltage supply ranges in substitute parts encompass or exceed the original 4.5V to 5.5V range.

Q: What is the difference between the 8-SOIC and 8-SOP packages?

A: The BR25H010F-2CE2 uses 8-SOP packaging with 4.40mm width, while other substitutes use 8-SOIC with 3.90mm width. Both are 8-pin surface mount packages with identical pin pitch and electrical compatibility. PCB layout verification is required when substituting between these package variants due to dimensional differences.

Q: Are all substitute parts RoHS compliant?

A: Yes, all substitute parts listed are ROHS3 compliant, addressing the RoHS non-compliance status of the obsolete AT25010N-10SC.

Q: Which substitute part offers the best performance?

A: The M95010 series from STMicroelectronics operates at 20 MHz, the highest clock frequency among substitutes. The BR25H010F-2CE2 offers the fastest write cycle time at 4ms and the widest operating temperature range to 125°C.

Q: Are automotive-grade options available?

A: Yes, BR25H010F-2CE2 and CAV25010VE-GT3 are both AEC-Q100 qualified for automotive applications.

Q: What is the inventory status of these substitute parts?

A: All substitute parts are in active production with available inventory: 25AA010A-I/SN (3,300 pcs), BR25H010F-2CE2 (702 pcs), CAV25010VE-GT3 (3,854 pcs), M95010-RMN6TP (3,405 pcs), M95010-WMN6P (2,134 pcs), and M95010-WMN6TP (40,291 pcs).
