Substitute Part Grouping Explanation

The MB7489-521 qualifies as a direct substitute for the MB7489-520 based on identical electrical and mechanical parameters. Substitution eligibility is determined by the following criteria:

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

The MB7489-521 maintains Active product status, providing long-term availability and supply chain continuity compared to the Obsolete MB7489-520.

Parameter Comparison

Engineering Selection Recommendations

The MB7489-521 is the direct substitute for MB7489-520 applications. Both components share identical electrical specifications, mechanical dimensions, and functional characteristics. The primary distinction is product lifecycle status: MB7489-520 is Obsolete while MB7489-521 maintains Active status. For new designs and ongoing procurement, MB7489-521 is the appropriate selection. Both components maintain ROHS3 compliance and equivalent regulatory classification (ECCN: EAR99, HTSUS: 8543.70.4500).

Frequently Asked Questions (FAQ)

Q: Can MB7489-521 directly replace MB7489-520 in existing designs? A: Yes. Both components are electrically and mechanically identical across all specified parameters including frequency, voltage rating, beam angle, and operating temperature range.

Q: What is the primary reason to transition from MB7489-520 to MB7489-521? A: MB7489-520 carries Obsolete product status, limiting future availability. MB7489-521 maintains Active status, ensuring supply chain continuity and long-term procurement viability.

Q: Are there packaging differences between these parts? A: MB7489-520 packaging is listed as standard, while MB7489-521 is supplied in Bulk packaging. Verify packaging requirements for your application before procurement.

Q: Do both parts meet the same compliance standards? A: Yes. Both MB7489-520 and MB7489-521 are ROHS3 compliant with identical ECCN and HTSUS classifications.

Q: What are the critical parameters for substitution compatibility? 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.
