BR95320-WMN6TP EEPROM 32Kbit SPI Equivalent & Substitute Parts

Part Overview

The BR95320-WMN6TP is a 32Kbit EEPROM memory IC manufactured by Rohm Semiconductor with SPI interface operating at 5 MHz. This device is classified as obsolete product status. Due to its obsolete classification, equivalent and substitute parts from active product lines are necessary to maintain design continuity and ensure long-term component availability for new production runs and system updates.

Substitute Part Grouping Explanation

Substitution for the BR95320-WMN6TP is determined by the following critical parameters: 32Kbit memory capacity, 4K x 8 organization, SPI interface, 8-SOIC package form factor, and operating temperature range of -40°C to 85°C. Clock frequency may vary upward from 5 MHz without functional impact, as higher-speed devices remain backward compatible. Supply voltage range must encompass or exceed 2.5V minimum to 5.5V maximum. All substitute parts must maintain ROHS3 compliance and MSL 1 rating. Parts with lower memory capacity (8Kbit) or different package types are excluded from direct substitution.

Engineering Selection Recommendations

Primary substitutes are BR25G320FJ-3GE2 and BR25S320FJ-WE2 from Rohm Semiconductor, maintaining manufacturer continuity while transitioning to active product status. Both devices feature identical 8-SOIC packaging and operating temperature range, with enhanced clock frequency specifications. BR25G320FJ-3GE2 offers the lowest minimum supply voltage at 1.6V, providing expanded operational margin.

Microchip Technology 25LC320 series devices provide secondary substitution options with verified ROHS3 compliance and MSL 1 rating. The 25LC320-I/SN and 25LC320-E/SN variants match the original 2.5V minimum supply voltage requirement. The 25LC320A-E/SN variant extends operating temperature to 125°C, suitable for applications requiring enhanced thermal performance.

Microchip 25AA320 series devices operate at reduced minimum supply voltage (1.8V) and are suitable for low-power applications. The 25AA320A-I/SN and 25AA320AT-I/SN variants provide 10 MHz clock frequency, matching or exceeding the original 5 MHz specification.

All recommended substitutes maintain 32Kbit capacity, 4K x 8 organization, SPI interface, 8-SOIC package form factor, and ROHS3 compliance. Selection should prioritize active product status and supply voltage compatibility with existing system design parameters.

Frequently Asked Questions (FAQ)

Q: Can BR25G320FJ-3GE2 directly replace BR95320-WMN6TP?

A: Yes. Both devices share identical 32Kbit capacity, 4K x 8 organization, SPI interface, 8-SOIC package, and -40°C to 85°C operating temperature range. BR25G320FJ-3GE2 operates at 20 MHz versus the original 5 MHz, providing backward compatibility. The lower minimum supply voltage (1.6V) expands operational margin.

Q: What is the difference between 25LC320-I/SN and 25LC320-E/SN?

A: Both devices are identical in electrical specifications: 32Kbit capacity, 2 MHz clock frequency, 2.5V to 5.5V supply range, and 8-SOIC package. The primary difference is operating temperature range: 25LC320-I/SN operates -40°C to 85°C, while 25LC320-E/SN operates -40°C to 125°C.

Q: Why do Microchip 25AA320 variants specify 1.8V minimum supply voltage?

A: The 25AA320 series is designed for low-power applications with extended supply voltage flexibility. The 1.8V minimum is lower than the original BR95320-WMN6TP specification of 2.5V. Designs operating at 2.5V or higher remain fully compatible.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original device specifications.

Q: Can 25LC080BT-E/SN substitute for BR95320-WMN6TP?

A: No. The 25LC080BT-E/SN is an 8Kbit device with 1K x 8 organization, providing one-quarter the memory capacity of the BR95320-WMN6TP. Memory capacity is a non-negotiable substitution parameter.
