Substitute Part Grouping Explanation

Substitution of the MB7789-720 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part must satisfy the following criteria:

• Identical frequency: 42kHz
• Identical voltage rating: 10 V ~ 32 V
• Identical beam angle: 23°
• Identical operating temperature range: -40°C ~ 65°C
• Identical functional type: Transmitter and Receiver
• Same series classification: 4-20SC-MaxSonar-WR
• Equivalent or superior product status and compliance certifications

The MB7789-721 meets all substitution criteria as an active product variant within the same series, maintaining full electrical and mechanical compatibility with the obsolete MB7789-720.
