Key Parameters

Substitute Part Grouping Explanation

Substitution for the BD3532F-RE2 is based on the following critical parameters:

• Functional equivalence: Single-output voltage regulator for DDR bus termination
• Input voltage compatibility: 4.3V ~ 5.5V operating range
• Package compatibility: 8-SOP surface mount package
• Thermal performance: Operating temperature range of -40°C ~ 100°C
• Manufacturer continuity: Rohm Semiconductor product line

The BD3539NUX-BZTR meets these substitution criteria as an active product from the same manufacturer with identical package specifications and functional application scope.

Engineering Selection Recommendations

The BD3539NUX-BZTR is the manufacturer-recommended substitute for the BD3532F-RE2. Selection of this alternative is justified by:

• Product status alignment: The BD3539NUX-BZTR maintains Active status, ensuring long-term availability and supply chain continuity
• Functional compatibility: Both devices serve identical DDR bus termination regulator applications with single-output configuration
• Package compatibility: Both utilize 8-SOP surface mount packaging, enabling direct board-level substitution
• Manufacturer consistency: Rohm Semiconductor maintains design continuity across both part numbers

The transition from BD3532F-RE2 (Last Time Buy) to BD3539NUX-BZTR (Active) is appropriate for new designs and production continuity.

Frequently Asked Questions (FAQ)

Q: Can the BD3539NUX-BZTR be used as a direct replacement for the BD3532F-RE2?

A: Yes. Both devices are single-output DDR bus termination regulators in 8-SOP packages from Rohm Semiconductor. The BD3539NUX-BZTR is the manufacturer-recommended substitute and maintains Active product status.

Q: Are there package compatibility concerns between these parts?

A: No. Both the BD3532F-RE2 and BD3539NUX-BZTR use 8-SOP surface mount packaging with identical pinout compatibility for DDR bus termination applications.

Q: Why is the BD3532F-RE2 in Last Time Buy status?

A: Last Time Buy status indicates the manufacturer is discontinuing production. The BD3539NUX-BZTR is the active replacement product from Rohm Semiconductor.

Q: What parameters must match for substitution eligibility?

A: Critical parameters include input voltage range (4.3V ~ 5.5V), single output configuration, operating temperature range (-40°C ~ 100°C), 8-SOP package format, and DDR bus termination regulator function.

Q: Is the BD3539NUX-BZTR available in inventory?

A: Yes. The BD3539NUX-BZTR has 1089 pieces in new original stock.
