Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB7789-220 is determined by strict equivalence across the following critical parameters:

• Frequency: 42kHz (identical operating frequency required for system compatibility)
• Voltage Rating: 10 V ~ 32 V (identical supply voltage range)
• Beam Angle: 23° (identical detection geometry)
• Operating Temperature Range: -40°C ~ 65°C (identical thermal operating envelope)
• Type: Transmitter, Receiver (identical functional configuration)
• Series: 4-20SC-MaxSonar-WR (same product family)
• Base Product Number: MB7789 (same base platform)
• RoHS Status: ROHS3 Compliant (identical compliance certification)

The MB7789-221 meets all substitution criteria as a direct equivalent within the same manufacturer series. The primary distinction is product status: MB7789-221 is active and currently manufactured, whereas MB7789-220 is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The MB7789-221 is a direct functional equivalent to the MB7789-220 with identical electrical and mechanical specifications. Selection of MB7789-221 is supported by:
