Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB7789-620 is based on electrical and mechanical parameter alignment within the MaxBotix 4-20SC-MaxSonar-WR series. The substitute part must maintain identical specifications across the following critical parameters:

• Operating frequency: 42kHz
• Voltage rating: 10 V ~ 32 V
• Beam angle: 23°
• Operating temperature range: -40°C ~ 65°C
• Functional type: Transmitter and Receiver
• Series designation: 4-20SC-MaxSonar-WR
• RoHS compliance: ROHS3 Compliant

The MB7789-621 meets all these criteria and is classified as an active product, providing continuity for applications currently using the obsolete MB7789-620.

Parameter Comparison

Engineering Selection Recommendations

The MB7789-621 is the direct substitute for the MB7789-620. Both components are manufactured by MaxBotix Inc. within the same product series and maintain identical electrical and mechanical specifications. The MB7789-621 carries active product status, ensuring availability and ongoing manufacturer support. Both parts maintain ROHS3 compliance and equivalent export classification (EAR99, HTSUS 8543.70.4500).

Selection of the MB7789-621 for new designs or replacement applications eliminates obsolescence risk while preserving full functional and electrical compatibility with existing MB7789-620 installations.
