Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMA6863MZ are identified based on strict electrical and mechanical compatibility criteria. The following parameters define acceptable substitution:

Critical Matching Parameters:

• Motor Type: Brushless DC (BLDC)
• Function: Driver
• Output Configuration: Half Bridge (3)
• Interface: Logic
• Technology: Power MOSFET
• Current - Output: 2.5A
• Mounting Type: Through Hole
• Package / Case: 24-SSIP Formed Leads

Allowable Parameter Variations:

• Voltage - Supply: May vary within operational design margins
• Voltage - Load (Max): May exceed original specification
• Operating Temperature Range: May be narrower or equal to original
• Product Status: Active or Obsolete
• Supplier Device Package: Equivalent 24-position packages

Two substitute parts meet these criteria: SMA6863MH (manufacturer-recommended) and SMA6865MZ-LF2451 (parametric equivalent).

Engineering Selection Recommendations

SMA6863MH (Manufacturer-Recommended Substitute): This part is the preferred substitute, designated as active by the manufacturer. It maintains identical motor driver functionality, output configuration, and current rating. The supply voltage range (14.6V ~ 16.5V) differs from the original 20V specification, and the maximum load voltage increases to 500V. This part is suitable for applications where the supply voltage operates within the specified range. The active product status ensures ongoing manufacturer support and availability.

SMA6865MZ-LF2451 (Parametric Equivalent): This part provides electrical equivalence to the original SMA6863MZ, matching the 20V supply voltage and 400V maximum load voltage specifications. It maintains identical current output, motor type, and interface characteristics. The part is classified as obsolete, similar to the original component. This substitute is appropriate for direct replacement in existing designs where supply voltage specifications are critical. RoHS compliance is confirmed.

Both substitutes maintain through-hole mounting and 24-SSIP package compatibility, ensuring mechanical interchangeability in existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can SMA6863MH be used as a direct replacement for SMA6863MZ? A: SMA6863MH is electrically compatible for BLDC motor driver applications with identical output configuration and current rating. The supply voltage range differs (14.6V ~ 16.5V versus 20V). Verify that your application's supply voltage operates within the SMA6863MH range before substitution.

Q: What is the difference between SMA6863MH and SMA6865MZ-LF2451? A: Both are compatible substitutes. SMA6863MH is manufacturer-recommended and active. SMA6865MZ-LF2451 is a parametric equivalent with identical voltage specifications to the original SMA6863MZ but is obsolete. Choose SMA6863MH for new designs or ongoing support; use SMA6865MZ-LF2451 for direct electrical replacement in existing applications.

Q: Are these substitutes mechanically compatible with the original part? A: Yes. All three parts use 24-SSIP formed leads packaging with through-hole mounting. PCB layouts designed for SMA6863MZ accommodate both substitute parts without modification.

Q: Does the operating temperature range affect substitution? A: SMA6863MH specifies only a maximum junction temperature of 150°C, whereas SMA6863MZ and SMA6865MZ-LF2451 specify -20°C ~ 150°C. For applications requiring operation below 0°C, use SMA6863MZ or SMA6865MZ-LF2451.

Q: Are all parts RoHS compliant? A: SMA6863MZ and SMA6865MZ-LF2451 are confirmed RoHS compliant. RoHS status for SMA6863MH is not specified in available documentation.
