Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB7769-220 is based on electrical and mechanical parameter equivalence within the MaxBotix 4-20SC-MaxSonar-WR series. The MB7769-221 qualifies as a direct substitute because it maintains identical specifications across all critical parameters: 42kHz operating frequency, 10 V ~ 32 V rated voltage, 23° beam angle, -40°C ~ 65°C operating temperature range, and ROHS3 compliance. Both parts function as transmitter-receiver units within the same product series and base product family (MB7769).

The primary distinction between these parts is product status: MB7769-220 is obsolete while MB7769-221 is active, and packaging configuration (MB7769-220 uses standard packaging while MB7769-221 is supplied in bulk).

Parameter Comparison

Engineering Selection Recommendations

The MB7769-221 is the direct substitute for MB7769-220. Selection of MB7769-221 is supported by:

• Identical electrical specifications across frequency, voltage rating, and operating temperature range
• Matching mechanical parameters including beam angle and sensor type
• Active product status ensuring ongoing availability and supply chain continuity
• ROHS3 compliance maintained across both parts
• Same base product family (MB7769) and series designation (4-20SC-MaxSonar-WR)

For applications currently using MB7769-220, transition to MB7769-221 requires no circuit redesign or application modification. Bulk packaging of MB7769-221 may require adjustment to procurement and inventory management procedures.

Frequently Asked Questions (FAQ)

Q: Can MB7769-221 replace MB7769-220 in existing designs?

A: Yes. MB7769-221 is electrically and mechanically equivalent to MB7769-220. All functional parameters, including frequency, voltage rating, beam angle, and operating temperature range, are identical. No circuit modifications are required.

Q: What is the difference between MB7769-220 and MB7769-221?

A: The primary differences are product status and packaging. MB7769-220 is obsolete with standard packaging, while MB7769-221 is active with bulk packaging. All electrical and mechanical specifications are identical.

Q: Why is MB7769-220 listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured. MB7769-221 serves as the active equivalent for continued system support and new designs.

Q: Are there compliance differences between these parts?

A: No. Both MB7769-220 and MB7769-221 maintain ROHS3 compliance and share identical ECCN (EAR99) and HTSUS (8543.70.4500) classifications.

Q: Does packaging affect electrical performance?

A: No. Bulk packaging of MB7769-221 does not affect electrical or mechanical performance. Packaging differences relate only to order quantity and storage considerations.
