Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB7489-730 is determined by strict equivalence across the following critical parameters:

• Frequency: 42kHz (exact match required)
• Voltage Rating: 10V ~ 32V (exact match required)
• Beam Angle: 23° (exact match required)
• Operating Temperature Range: -40°C ~ 65°C (exact match required)
• Type Configuration: Transmitter and Receiver (exact match required)
• Series: 4-20HR-MaxSonar-WR (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The MB7489-731 meets all substitution criteria as an active equivalent within the same product series and base product family (MB7489).

Parameter Comparison

Engineering Selection Recommendations

The MB7489-731 is the direct equivalent substitute for the obsolete MB7489-730. Both components share identical electrical specifications, mechanical characteristics, and regulatory compliance certifications. The primary distinction is product status: MB7489-730 is obsolete with 785 units in stock, while MB7489-731 is active with 937 units available. For new designs and ongoing procurement, MB7489-731 is the appropriate selection. For legacy system maintenance where MB7489-730 stock exists, either part may be used interchangeably within the same application context.

Frequently Asked Questions (FAQ)
