Key Parameters

Substitute Part Grouping Explanation

Substitution for the MB7489-120 is strictly determined by matching key parameters: ultrasonic sensor category, identical series (4-20HR-MaxSonar-WR), same transmitter/receiver configuration, operating frequency of 42kHz, rated voltage range from 10 V to 32 V, beam angle of 11°, operating temperature spanning -40°C to 65°C, and ROHS3 compliance status. Only those part numbers meeting these specific criteria are considered valid engineering substitutes.

Parameter Comparison

Engineering Selection Recommendations

MB7489-120 is listed as obsolete. The substitute part MB7489-121 is currently active, shares all key technical specifications, series designation, compliance with ROHS3, and packaging format. For this product category, selection should prioritize active status and confirmed compliance based strictly on the parameters above.
