Substitute Part Grouping Explanation

The MB7789-631 qualifies as a direct substitute based on matching electrical and mechanical parameters across all critical specifications. Substitution eligibility is determined by the following parameters:

• Frequency: 42kHz (identical)
• Voltage Rating: 10V ~ 32V (identical)
• Beam Angle: 23° (identical)
• Operating Temperature Range: -40°C ~ 65°C (identical)
• Type: Transmitter, Receiver (identical)
• Series: 4-20SC-MaxSonar-WR (identical)
• Base Product Number: MB7789 (identical)
• RoHS Compliance: ROHS3 Compliant (identical)

The MB7789-631 maintains full electrical and mechanical compatibility with the obsolete MB7789-630, differing only in packaging configuration and product status.

Parameter Comparison

Engineering Selection Recommendations

The MB7789-631 is the designated substitute for the obsolete MB7789-630. Both components maintain identical electrical specifications, mechanical dimensions, and regulatory compliance certifications. The MB7789-631 is currently in active production status with confirmed inventory availability (747 pcs), whereas the MB7789-630 is obsolete with limited remaining stock (824 pcs).

Selection of the MB7789-631 ensures continued access to compatible components within the 4-20SC-MaxSonar-WR series while maintaining full functional equivalence. Packaging differences (bulk vs. standard) do not affect electrical or mechanical performance and should be evaluated based on procurement and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can the MB7789-631 directly replace the MB7789-630 in existing designs?
