Key Parameters

Substitute Part Grouping Explanation

The CMD-HHCP-315-MD qualifies as a direct substitute based on the following critical parameters:

• Frequency Match: Both operate at 315MHz
• Modulation Compatibility: Both support ASK and OOK modulation protocols
• Function Equivalence: Both are RF transmitters
• Interface Compatibility: Both feature handheld configuration with 8 buttons
• Supply Voltage Range: Both operate within 2.1V to 3.6V
• Application Alignment: Both are designed for general remote control, garage opener, and RKE applications

The CMD-HHCP-315-MD represents an active product status alternative, addressing the obsolescence of the original CMD-HHTX-315.

Parameter Comparison

Engineering Selection Recommendations

The CMD-HHCP-315-MD is the designated substitute for the obsolete CMD-HHTX-315. Both components share identical core RF specifications: 315MHz frequency, ASK/OOK modulation, handheld 8-button interface, and matching supply voltage range. The substitute maintains active product status, ensuring continued availability and manufacturing support.

Design considerations include the operating distance differential: the CMD-HHTX-315 specifies 1000 feet while the CMD-HHCP-315-MD specifies 750 feet. Systems requiring the full 1000-foot range must evaluate this parameter against application requirements. Both components carry identical REACH and ECCN classifications, maintaining regulatory equivalence. The CMD-HHCP-315-MD is supplied in bulk packaging and carries RoHS non-compliant status, consistent with legacy RF transmitter product lines.

Frequently Asked Questions (FAQ)

Q: Can the CMD-HHCP-315-MD directly replace the CMD-HHTX-315 in existing designs?

A: Yes. Both components operate at 315MHz with ASK/OOK modulation, identical supply voltage ranges (2.1V to 3.6V), and equivalent handheld 8-button interfaces. The primary design consideration is the operating distance specification: 750 feet for the substitute versus 1000 feet for the original.

Q: What is the significance of the operating distance difference?

A: The CMD-HHTX-315 specifies 1000 feet operating distance while the CMD-HHCP-315-MD specifies 750 feet. Applications requiring maximum range performance must evaluate whether this 250-foot reduction impacts system functionality.

Q: Are there compliance differences between these parts?

A: Both components share identical REACH and ECCN classifications. The CMD-HHCP-315-MD carries RoHS non-compliant status. Verify compliance requirements for your specific application and regulatory jurisdiction.

Q: What packaging formats are available?

A: The CMD-HHTX-315 packaging is not specified in available documentation. The CMD-HHCP-315-MD is supplied in bulk packaging.

Q: Why is the CMD-HHTX-315 listed as obsolete?

A: The CMD-HHTX-315 has reached end-of-life status. The CMD-HHCP-315-MD represents the active product continuation from TE Connectivity Linx for this application category.
