CMD-KEY1-418 Equivalent & Substitute Parts

Part Overview

The CMD-KEY1-418 is an RF transmitter keyfob operating at 418MHz with ASK/OOK modulation, designed for single-button handheld remote control applications including garage openers and remote keyless entry (RKE) systems. The device is classified as obsolete, making identification of active equivalent parts essential for ongoing procurement and system maintenance. The substitute part OTX-418-HH-KF1-HT provides functional continuity with active product status and identical core electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

The OTX-418-HH-KF1-HT qualifies as a direct substitute for CMD-KEY1-418 based on the following matching parameters:

• Frequency: 418MHz (identical)
• Modulation: ASK, OOK (identical)
• Function: Transmitter (identical)
• Interface: Handheld, 1 Button (identical)
• Voltage Supply: 2.1V ~ 3.6V (identical)
• Operating Distance: 750 ft. (identical)
• MSL Rating: 1 (Unlimited) (identical)
• REACH Compliance: REACH Unaffected (identical)

The primary distinction is product status: CMD-KEY1-418 is obsolete, while OTX-418-HH-KF1-HT maintains active status. Both parts are manufactured by TE Connectivity Linx and share identical electrical and mechanical specifications for the defined application parameters.

Parameter Comparison

Engineering Selection Recommendations
