Key Parameters

Substitute Part Grouping Explanation

The MB7769-521 qualifies as a direct substitute for the MB7769-520 based on the following criteria:

• Identical frequency specification (42kHz)
• Matching voltage rating (10 V ~ 32 V)
• Identical beam angle (23°)
• Identical operating temperature range (-40°C ~ 65°C)
• Same functional type (Transmitter, Receiver)
• Same series designation (4-20SC-MaxSonar-WR)
• Equivalent RoHS compliance (ROHS3)

The substitution is driven by product status: MB7769-520 is obsolete while MB7769-521 is active, ensuring continued supply chain availability.

Parameter Comparison

Engineering Selection Recommendations

The MB7769-521 is the appropriate selection for applications currently using or specifying the MB7769-520. Both components maintain identical electrical and mechanical parameters across all critical specifications. The transition from MB7769-520 to MB7769-521 is driven by product lifecycle status: the MB7769-520 is obsolete while the MB7769-521 remains in active production. Both components carry ROHS3 compliance and equivalent regulatory classifications (ECCN: EAR99; HTSUS: 8543.70.4500), ensuring compliance continuity. The MB7769-521 is available in bulk packaging with current inventory of 687 units.

Frequently Asked Questions (FAQ)

Q: Can MB7769-521 directly replace MB7769-520 in existing designs?

A: Yes. The MB7769-521 maintains identical electrical specifications (42kHz frequency, 10-32V rating, 23° beam angle, -40°C to 65°C operating range) and functional type (Transmitter, Receiver). No circuit modifications are required.
