CMD-HHCP-418 Equivalent & Substitute Parts

Part Overview

The CMD-HHCP-418 is an RF transmitter operating at 418MHz with ASK/OOK modulation, designed for handheld remote control applications. This 8-button transmitter delivers 1.2kbps data rate with an operating distance of 1000 feet and operates across a 2.1V to 3.6V supply voltage range. The part is currently classified as obsolete, making identification of compatible substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMD-HHCP-418 is determined by the following critical parameters:

• Frequency: 418MHz (exact match required)
• Modulation/Protocol: ASK, OOK (exact match required)
• Function: Transmitter (exact match required)
• Interface: Handheld, 8 Button (exact match required)
• Voltage Supply Range: 2.1V – 3.6V (must be compatible)
• Base Product Number: CMD-HHCP (same product family)

The CMD-HHCP-418-MD meets all substitution criteria as a direct equivalent within the CMD-HHCP product family, maintaining identical frequency, modulation scheme, interface configuration, and supply voltage specifications.

Parameter Comparison

Engineering Selection Recommendations

The CMD-HHCP-418-MD is the direct substitute for the obsolete CMD-HHCP-418. Both components share identical core electrical specifications: 418MHz frequency, ASK/OOK modulation, 8-button handheld interface, and 2.1V–3.6V supply voltage compatibility.

The CMD-HHCP-418-MD carries active product status and RoHS compliance certification, addressing regulatory requirements for new designs and ongoing production. The operating distance reduction from 1000 feet to 750 feet and unspecified data rate in the substitute part represent the primary technical differences; system integration must account for these variations.

Both parts maintain REACH unaffected status and identical ECCN/HTSUS classifications, ensuring consistent export and regulatory treatment.

Frequently Asked Questions (FAQ)

Q: Can CMD-HHCP-418-MD directly replace CMD-HHCP-418 in existing designs?

A: Yes. Both parts operate at 418MHz with ASK/OOK modulation, identical supply voltage range (2.1V–3.6V), and 8-button handheld interface. The operating distance difference (750 ft vs. 1000 ft) must be evaluated within your specific application requirements.

Q: What is the primary reason for substitution?

A: The CMD-HHCP-418 is obsolete. The CMD-HHCP-418-MD is the active equivalent from the same manufacturer and product family.

Q: Are there packaging differences between these parts?

A: The CMD-HHCP-418-MD is supplied in bulk packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: Does the CMD-HHCP-418-MD meet RoHS requirements?

A: Yes. The CMD-HHCP-418-MD is RoHS compliant, whereas the original CMD-HHCP-418 is RoHS non-compliant. This is advantageous for regulatory compliance in new designs.

Q: Are there differences in data rate specifications?

A: The CMD-HHCP-418 specifies 1.2kbps maximum data rate. The CMD-HHCP-418-MD does not provide a published data rate specification. Consult TE Connectivity Linx technical documentation for detailed performance characteristics.
