Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB7789-520 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: 4-20SC-MaxSonar-WR (same product family)
• RoHS Compliance: ROHS3 Compliant (regulatory equivalence)

The MB7789-521 meets all substitution criteria as an active product within the same series, maintaining identical electrical and mechanical specifications while offering improved availability.

Parameter Comparison

Engineering Selection Recommendations

The MB7789-521 is the direct substitute for the MB7789-520. Both components maintain identical electrical specifications, mechanical dimensions, and regulatory compliance. The primary distinction is product status: the MB7789-520 is obsolete while the MB7789-521 is active. For new designs and ongoing production, the MB7789-521 is the appropriate selection. Both components carry ROHS3 compliance and equivalent export classification (EAR99), ensuring regulatory parity in applications requiring these certifications.
