Key Parameters

Substitute Part Grouping Explanation

Substitution for the SEN-09495 is determined by strict alignment of the following electrical and mechanical parameters:

• Frequency: 42kHz operation is the primary functional requirement
• Type: Must function as both transmitter and receiver
• Voltage Range: Operating voltage must be compatible with system design (3.3 V ~ 5 V minimum overlap required)
• Operating Temperature Range: Must support -40°C ~ 65°C (TA) minimum
• Series Compatibility: XL-MaxSonar-EZ series designation indicates functional equivalence
• RoHS Compliance: Must meet RoHS requirements for regulatory compliance
• Moisture Sensitivity Level: MSL 1 (Unlimited) indicates no moisture sensitivity constraints

The MB1240-000 from MaxBotix Inc. meets all substitution criteria as an active product within the XL-MaxSonar-EZ series with identical frequency and functional characteristics.

Engineering Selection Recommendations

The MB1240-000 is the direct substitute for the SEN-09495. Selection is based on the following engineering criteria:

• Functional Equivalence: Both parts operate at 42kHz with identical transmitter/receiver functionality
• Electrical Compatibility: The MB1240-000 voltage range (3.2 V ~ 5.5 V) encompasses the SEN-09495 requirement (3.3 V ~ 5 V), ensuring drop-in compatibility in existing designs
• Thermal Performance: Identical operating temperature range (-40°C ~ 65°C) maintains system thermal specifications
• Regulatory Compliance: MB1240-000 meets ROHS3 compliance, exceeding the RoHS requirement of the obsolete part
• Product Availability: MB1240-000 is an active product with confirmed inventory, addressing the obsolescence of SEN-09495
• Series Continuity: Both parts belong to the XL-MaxSonar-EZ product family, ensuring design continuity

Frequently Asked Questions (FAQ)

Q: Can the MB1240-000 directly replace the SEN-09495 in existing designs?

A: Yes. The MB1240-000 meets all electrical and functional parameters of the SEN-09495. The voltage range of the substitute (3.2 V ~ 5.5 V) is wider than the original (3.3 V ~ 5 V), providing enhanced compatibility. Operating temperature ranges are identical.

Q: What is the primary reason for substitution?

A: The SEN-09495 is obsolete. The MB1240-000 is an active product from MaxBotix Inc. within the same XL-MaxSonar-EZ series, providing continued availability for new procurement and system support.

Q: Are there packaging differences between these parts?

A: The SEN-09495 packaging is listed as "-" (unspecified). The MB1240-000 is supplied in Bulk packaging. Verify packaging requirements for your specific application.

Q: Do both parts have the same frequency specification?

A: Yes. Both the SEN-09495 and MB1240-000 operate at 42kHz, ensuring identical functional performance in ultrasonic distance measurement applications.

Q: What compliance certifications apply to the substitute?

A: The MB1240-000 is ROHS3 compliant and carries the same ECCN (EAR99) and HTSUS (8543.70.4500) classifications as the original part, maintaining regulatory alignment.

Q: Is the beam angle specification relevant for substitution?

A: The SEN-09495 beam angle is not specified in available data. The MB1240-000 has a 38° beam angle. Verify beam angle requirements for your application to confirm suitability.
