BR93L76RFVT-WE2 Equivalent & Substitute Parts

Part Overview

The BR93L76RFVT-WE2 is an 8Kbit EEPROM memory IC manufactured by Rohm Semiconductor, featuring Microwire serial interface protocol and 2 MHz clock frequency. This device is designed for non-volatile data storage applications requiring low-power operation across industrial temperature ranges. The part is currently in active production status with verified programmability through DiGi-Electronics.

Substitute parts become necessary when the primary part experiences supply constraints, inventory depletion, or when design requirements permit operation at alternative clock frequencies while maintaining core functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BR93L76RFVT-WE2 is determined by the following critical parameters:

Core Compatibility Requirements:

• Memory capacity: 8Kbit (512 x 16 organization)
• Interface protocol: Microwire serial interface
• Package: 8-TSSOP-B form factor
• Write cycle time: 5ms maximum
• Operating temperature range: -40°C ~ 85°C minimum
• Supply voltage: Overlapping range with 1.8V ~ 5.5V

Variable Parameters Permitting Substitution:

• Clock frequency: Higher frequencies (3 MHz) are acceptable for designs not requiring strict 2 MHz operation
• Supply voltage range: Slight variations acceptable if minimum 1.8V and maximum 5.5V are maintained
• Product status: Active or Obsolete parts may substitute if electrical parameters align

The BR93G76FVT-3BGE2 qualifies as a substitute based on identical memory capacity, organization, interface protocol, package type, and write cycle time, with the primary difference being elevated clock frequency (3 MHz vs. 2 MHz).

Engineering Selection Recommendations

Primary Part Selection (BR93L76RFVT-WE2): The BR93L76RFVT-WE2 is the preferred selection for new designs. This part maintains active production status, verified programmability certification through DiGi-Electronics, and current inventory availability (2559 pcs). All compliance certifications including ROHS3, REACH Unaffected, and EAR99 ECCN classification are current.

Substitute Part Consideration (BR93G76FVT-3BGE2): The BR93G76FVT-3BGE2 may be selected when the primary part is unavailable. This substitute maintains electrical and mechanical compatibility across all critical parameters. However, the following conditions apply:

• Product status is Obsolete, indicating no ongoing manufacturing support
• Programmability has not been verified through DiGi-Electronics
• Clock frequency operates at 3 MHz, requiring circuit design confirmation that timing constraints are satisfied
• Minimum supply voltage is 1.7V (versus 1.8V for the primary part), which may affect operation in low-voltage applications

Selection of the substitute part requires confirmation that the application circuit can operate at 3 MHz clock frequency and that the 1.7V minimum supply voltage does not conflict with system power delivery specifications.

Frequently Asked Questions (FAQ)

Q: Can BR93G76FVT-3BGE2 be used as a direct replacement for BR93L76RFVT-WE2?

A: Electrical and mechanical substitution is possible. The substitute part maintains identical memory capacity (8Kbit), organization (512 x 16), Microwire interface protocol, 8-TSSOP-B package, and write cycle time (5ms). The primary difference is clock frequency (3 MHz vs. 2 MHz). Direct replacement requires confirmation that the application circuit operates correctly at the higher clock frequency and that timing-dependent operations remain within specification.

Q: What is the impact of the 3 MHz clock frequency on the substitute part?

A: The BR93G76FVT-3BGE2 operates at 3 MHz, which is 50% faster than the 2 MHz specification of the primary part. This higher frequency does not degrade functionality but requires verification that the host microcontroller or interface circuit can support 3 MHz Microwire protocol operation. Applications designed for 2 MHz operation will function correctly at 3 MHz, as the substitute part remains backward-compatible with lower-frequency operation.

Q: Are there supply voltage compatibility concerns between these parts?

A: The primary part (BR93L76RFVT-WE2) operates from 1.8V to 5.5V, while the substitute (BR93G76FVT-3BGE2) operates from 1.7V to 5.5V. The substitute part has a lower minimum voltage specification. In applications operating above 1.8V, both parts are compatible. In applications operating between 1.7V and 1.8V, only the substitute part will function, but this scenario is uncommon in industrial designs.

Q: What is the significance of the "Obsolete" product status for BR93G76FVT-3BGE2?

A: Obsolete status indicates that Rohm Semiconductor has discontinued manufacturing of this part. Existing inventory may be available through authorized distributors, but no new production runs are scheduled. The substitute part should be considered only for immediate supply needs or as a temporary solution. For long-term production requirements, the active BR93L76RFVT-WE2 is the appropriate selection.

Q: Does the unverified programmability status of BR93G76FVT-3BGE2 affect functionality?

A: Unverified programmability status indicates that DiGi-Electronics has not completed formal verification testing for this part. This does not necessarily indicate functional deficiency but rather reflects the obsolete status and reduced testing priority. Rohm Semiconductor's original specifications remain valid. Applications requiring certified programmability should prioritize the BR93L76RFVT-WE2.

Q: Are both parts RoHS compliant?

A: Yes. Both BR93L76RFVT-WE2 and BR93G76FVT-3BGE2 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.
