Key Parameters

Substitute Part Grouping Explanation

The MB7769-621 qualifies as a direct substitute for the MB7769-620 based on the following criteria:

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

Both parts share the same base product number (MB7769), confirming their functional equivalence. The primary distinction is product status: MB7769-620 is obsolete while MB7769-621 is active.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using MB7769-620, the MB7769-621 is the appropriate selection. Both components maintain identical electrical performance specifications and environmental ratings. The MB7769-621 is the active product offering from MaxBotix Inc. and carries current ROHS3 compliance certification. Packaging differs between the two variants (MB7769-620 uses standard packaging while MB7769-621 is supplied in bulk), which may affect procurement and inventory management but does not impact functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can MB7769-621 directly replace MB7769-620 in existing designs?

A: Yes. Both parts share identical electrical specifications, frequency, voltage rating, beam angle, and operating temperature range. The substitution is functionally transparent at the circuit level.

Q: What is the primary reason for substitution?

A: MB7769-620 is classified as obsolete. MB7769-621 is the active equivalent from the same manufacturer and series, ensuring continued availability and support.

Q: Are there packaging differences between these parts?

A: Yes. MB7769-620 uses standard packaging while MB7769-621 is supplied in bulk packaging. This affects procurement logistics but not electrical or mechanical performance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both MB7769-620 and MB7769-621 are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8543.70.4500) classifications.

Q: What parameters must remain constant for substitution validity?

A: Frequency (42kHz), voltage rating (10 V ~ 32 V), beam angle (23°), operating temperature range (-40°C ~ 65°C), and functional type (Transmitter, Receiver) must all match. All parameters are identical between these two parts.
