Key Parameters

Substitute Part Grouping Explanation

The MB7760-621 qualifies as a direct substitute for the MB7760-620 based on matching specifications across all critical electrical and mechanical parameters. Both parts share identical frequency (42kHz), voltage rating (10 V ~ 32 V), beam angle (23°), operating temperature range (-40°C ~ 65°C), and functional type (Transmitter, Receiver). Both components comply with ROHS3 and carry the same ECCN and HTSUS classifications. The substitution is valid because all allowed parameters for ultrasonic sensor selection—frequency, voltage tolerance, beam angle, temperature range, and compliance certifications—are identical between the two parts.

Parameter Comparison

Engineering Selection Recommendations

The MB7760-621 is the appropriate selection for applications currently using or specifying the MB7760-620. As an active product with identical electrical and mechanical parameters, the MB7760-621 provides direct compatibility while ensuring ongoing supply chain availability. Both parts maintain ROHS3 compliance and equivalent regulatory classifications (ECCN: EAR99, HTSUS: 8543.70.4500). For new designs or system refreshes, the MB7760-621 should be specified to avoid obsolescence constraints.

Frequently Asked Questions (FAQ)

Q: Can MB7760-621 replace MB7760-620 in existing applications? A: Yes. Both parts operate at 42kHz with identical voltage ratings (10 V ~ 32 V), beam angle (23°), and temperature range (-40°C ~ 65°C). All electrical and mechanical parameters match, ensuring direct functional equivalence.

Q: What is the primary difference between these parts? A: The MB7760-620 is obsolete, while the MB7760-621 is active. Packaging differs (MB7760-620 is listed as "-" versus MB7760-621 as "Bulk"), but electrical specifications are identical.

Q: Are there compliance or certification differences? A: No. Both parts are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8543.70.4500) classifications.

Q: Which part should be specified for new designs? A: The MB7760-621 should be specified for new designs to ensure supply availability and avoid obsolescence issues.

Q: Are there inventory considerations? A: The MB7760-620 has 889 units in stock (obsolete status), while the MB7760-621 has 748 units available (active status). For long-term projects, the active MB7760-621 is the preferred choice.
