Substitute Part Grouping Explanation

Substitution of the MB7760-520 with the MB7760-521 is based on matching the following critical parameters:

• Operating 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, Receiver (identical)
• Series classification: 4-20SC-MaxSonar-WR (identical)
• RoHS compliance: ROHS3 Compliant (identical)

The MB7760-521 maintains full electrical and mechanical compatibility with the MB7760-520, with the primary distinction being product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The MB7760-521 is the direct equivalent for the obsolete MB7760-520. Both components are ROHS3 compliant and carry identical EAR99 export classification and HTSUS codes. The MB7760-521 is currently in active production status with confirmed inventory availability, making it the appropriate selection for replacement applications. No functional or electrical derating is required when substituting the MB7760-520 with the MB7760-521.

Frequently Asked Questions (FAQ)

Q: Can the MB7760-521 directly replace the MB7760-520 in existing designs?

A: Yes. The MB7760-521 maintains identical electrical specifications (42kHz frequency, 10-32V rating, 23° beam angle, -40°C to 65°C operating range) and functional classification as transmitter/receiver. Direct substitution is supported without circuit modification.

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

A: The MB7760-520 is obsolete, while the MB7760-521 is active production. Both are from the 4-20SC-MaxSonar-WR series with identical performance parameters. The packaging differs (MB7760-520 standard vs. MB7760-521 bulk), but electrical and mechanical specifications are equivalent.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the MB7760-520 and MB7760-521 are ROHS3 compliant with matching EAR99 export classification.

Q: What parameters must remain constant for ultrasonic sensor substitution in this series?

A: Operating frequency (42kHz), voltage rating (10-32V), beam angle (23°), and operating temperature range (-40°C to 65°C) are the critical parameters that define compatibility within the 4-20SC-MaxSonar-WR series.
