Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMD-KEY2-433 is determined by the following critical parameters:

• Frequency: 433MHz (exact match required)
• Modulation/Protocol: ASK, OOK (exact match required)
• Function: Transmitter (exact match required)
• Interface: Handheld, 2 Button (exact match required)
• Voltage Supply Range: 2.1V ~ 3.6V (exact match required)
• Operating Distance: 750 ft. (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The OTX-433-HH-KF2-HT meets all substitution criteria, maintaining identical electrical specifications, modulation characteristics, and physical interface requirements.

Parameter Comparison

Engineering Selection Recommendations

The OTX-433-HH-KF2-HT is the direct substitute for the CMD-KEY2-433. Both components share identical electrical and functional specifications across all critical parameters. The primary distinction is product status: the CMD-KEY2-433 is obsolete while the OTX-433-HH-KF2-HT is active, making the latter the appropriate choice for new procurement and system continuity.

The OTX-433-HH-KF2-HT carries RoHS Compliant certification, providing additional regulatory compliance assurance. Both components maintain REACH Unaffected status and identical ECCN classifications, ensuring consistent export and regulatory treatment.
