Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB7789-530 is determined by strict parameter matching across the following criteria:

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

The MB7789-531 meets all substitution criteria and is classified as an active product, providing continuity for applications currently using the obsolete MB7789-530.

Parameter Comparison

Engineering Selection Recommendations

The MB7789-531 is the direct equivalent for the obsolete MB7789-530. Both components share identical electrical specifications, mechanical parameters, and compliance certifications. The MB7789-531 maintains active product status with MaxBotix Inc., ensuring availability and continued manufacturer support. Selection of the MB7789-531 provides functional continuity without design modification or performance degradation. Packaging differs between the two parts (MB7789-530 standard vs. MB7789-531 bulk), which may affect procurement and inventory management but does not impact electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the MB7789-531 directly replace the MB7789-530 in existing designs?

A: Yes. The MB7789-531 is electrically and mechanically identical to the MB7789-530 across all specified parameters, including frequency, voltage rating, beam angle, and operating temperature range.

Q: What is the difference between MB7789-530 and MB7789-531?

A: The primary difference is product status and packaging. The MB7789-530 is obsolete, while the MB7789-531 is active. The MB7789-531 is supplied in bulk packaging, whereas the MB7789-530 uses standard packaging.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance, ECCN classification (EAR99), and HTSUS coding (8543.70.4500).

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

A: Frequency (42kHz), voltage rating (10V ~ 32V), beam angle (23°), operating temperature range (-40°C ~ 65°C), and functional type (Transmitter, Receiver) must remain constant for direct substitution within the 4-20SC-MaxSonar-WR series.
