Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB7789-700 is determined by strict equivalence across the following critical parameters:

• Frequency: 42kHz (exact match required)
• Voltage Rating: 10 V ~ 32 V (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 Designation: 4-20SC-MaxSonar-WR (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The MB7789-701 meets all substitution criteria as a direct equivalent within the same product series and base product family (MB7789).

Parameter Comparison

Engineering Selection Recommendations

The MB7789-701 is a direct functional equivalent to the MB7789-700 across all critical electrical and mechanical parameters. The primary distinction is product status: the MB7789-700 is obsolete while the MB7789-701 remains active in the manufacturer's product line. Both components maintain ROHS3 compliance and identical electrical specifications, ensuring seamless integration into existing circuit designs. Selection of the MB7789-701 is supported by its active status and confirmed availability, making it the appropriate choice for new procurement and system continuity.

Frequently Asked Questions (FAQ)

Q: Can the MB7789-701 replace the MB7789-700 in existing designs?

A: Yes. Both components share identical electrical specifications (42kHz frequency, 10V–32V rated voltage, 23° beam angle, -40°C to 65°C operating range) and functional configuration (transmitter/receiver). No circuit modifications are required.

Q: What is the difference between these two part numbers?

A: The MB7789-700 is classified as obsolete, while the MB7789-701 is active. Packaging differs (unspecified for MB7789-700 versus Bulk for MB7789-701). All electrical and mechanical parameters are identical.

Q: Are there any compliance differences?

A: No. Both components are ROHS3 compliant with matching ECCN (EAR99) and HTSUS (8543.70.4500) classifications.

Q: Does packaging affect electrical performance?

A: No. Packaging designation does not alter the sensor's electrical characteristics or operational parameters. Selection should be based on procurement and inventory requirements.

Q: What parameters must match for substitution?

A: Frequency, voltage rating, beam angle, operating temperature range, type configuration, series designation, and RoHS compliance must all match exactly for direct substitution.
