SMA6865MZ Equivalent & Substitute Parts

Part Overview

The SMA6865MZ is a motor driver power MOSFET logic integrated circuit manufactured by Sanken Electric USA Inc., designed for brushless DC (BLDC) motor control applications in home appliances. This device features a half-bridge (3) output configuration with 2.5A output current capability and operates across a supply voltage of 20V with maximum load voltage handling of 400V. The part is currently classified as obsolete, making identification of equivalent and substitute components essential for ongoing system support, maintenance, and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMA6865MZ are identified based on strict alignment with the following critical parameters:

Primary Substitution Criteria:

• Manufacturer: Sanken Electric USA Inc.
• Motor Type: Brushless DC (BLDC)
• Function: Driver
• Technology: Power MOSFET
• Output Current: 2.5A
• Maximum Load Voltage: 400V
• RoHS Compliance: Required

Substitute Categories:

Parametric Equivalent (Full Compatibility): SMA6865MZ-LF2451 maintains identical electrical specifications, output configuration (Half Bridge 3), interface type (Logic), and thermal operating range (-20°C ~ 150°C). This part differs only in supplier device package designation (24-SIP, LF2451 versus 24-ZIP) and represents a direct functional equivalent.

Similar Substitute (Partial Compatibility): SMA6865MH shares the same manufacturer, BLDC motor driver function, power MOSFET technology, and 2.5A output current rating. However, this part operates at reduced supply voltage (14.6V ~ 16.5V versus 20V), features a different output configuration (Half Bridge 2 versus Half Bridge 3), uses parallel interface instead of logic interface, and operates at a lower maximum junction temperature (-20°C ~ 100°C versus -20°C ~ 150°C). This substitute is suitable only for applications where the reduced supply voltage and output configuration are compatible with system requirements.

Engineering Selection Recommendations

For Direct Replacement (Preferred): SMA6865MZ-LF2451 is the recommended substitute when component availability is required. This part maintains full electrical and functional equivalence to the SMA6865MZ, with identical output configuration, interface type, current rating, supply voltage, and thermal operating range. Both parts are classified as obsolete; however, SMA6865MZ-LF2451 currently maintains higher inventory availability (713 pieces versus 844 pieces). Both parts are RoHS compliant with identical moisture sensitivity classification (MSL 1).

For Alternative Applications: SMA6865MH may be considered only when system design permits operation at reduced supply voltage (14.6V ~ 16.5V) and the application requires only two half-bridge outputs instead of three. This part is currently active in production status, providing superior long-term availability compared to the obsolete SMA6865MZ. The reduced operating temperature range (-20°C ~ 100°C) must be verified against application thermal requirements. The parallel interface differs from the logic interface of the main part and requires circuit redesign for control signal compatibility.

Frequently Asked Questions (FAQ)

Q: Can SMA6865MZ-LF2451 be used as a direct drop-in replacement for SMA6865MZ?

A: Yes. SMA6865MZ-LF2451 is a parametric equivalent with identical electrical specifications, output configuration, interface type, and thermal operating range. The only difference is the supplier device package designation (24-SIP, LF2451 versus 24-ZIP). Both use 24-pin through-hole mounting with formed leads. Verify PCB footprint compatibility before installation.

Q: What are the key differences between SMA6865MZ and SMA6865MH?

A: SMA6865MH differs in three critical areas: (1) Supply voltage operates at 14.6V ~ 16.5V instead of 20V, (2) Output configuration is Half Bridge (2) instead of Half Bridge (3), and (3) Control interface is parallel instead of logic. These differences require circuit redesign and are not suitable for direct substitution in systems designed for the SMA6865MZ.

Q: Why is SMA6865MH listed as a substitute if it has different specifications?

A: SMA6865MH is classified as a similar substitute because it shares the same manufacturer, BLDC motor driver function, power MOSFET technology, 2.5A output current, and 400V maximum load voltage. It is suitable only for new designs or applications where the reduced supply voltage and output configuration are compatible with system requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. SMA6865MZ, SMA6865MZ-LF2451, and SMA6865MH are all RoHS compliant. All parts maintain MSL 1 (Unlimited) moisture sensitivity classification.

Q: What is the difference between the 24-ZIP and 24-SIP package designations?

A: Both designations refer to 24-pin single in-line package formats with through-hole mounting and formed leads. The ZIP and SIP designations are supplier-specific nomenclature for the same physical package type. PCB footprints are compatible.

Q: Which substitute should be selected for new designs?

A: For new designs requiring BLDC motor driver functionality with 20V supply voltage and three half-bridge outputs, SMA6865MZ-LF2451 maintains full compatibility with the original SMA6865MZ specifications. For applications permitting reduced supply voltage (14.6V ~ 16.5V) and two half-bridge outputs, SMA6865MH offers active production status and superior long-term availability.
