Key Parameters

Substitute Part Grouping Explanation

The CMD-HHCP-433-MD qualifies as a direct substitute based on the following critical parameters:

• Frequency Match: Both operate at 433MHz
• Modulation Protocol: Both use ASK/OOK modulation
• Function: Both are RF transmitters
• Interface Configuration: Both feature handheld design with 8 buttons
• Voltage Supply Range: Both operate within 2.1V ~ 3.6V
• Base Product Number: Both share CMD-HHCP base designation
• Regulatory Compliance: Both maintain identical ECCN (5A991G) and HTSUS (8525.50.3040) classifications

The substitute part CMD-HHCP-433-MD is currently in active production status, providing continuity for applications requiring 433MHz handheld RF transmission with 8-button interface configuration.

Parameter Comparison

Engineering Selection Recommendations

The CMD-HHCP-433-MD is the designated substitute for the obsolete CMD-HHCP-433. Selection of the active substitute part is supported by:

• Identical frequency, modulation protocol, and interface specifications
• Matching voltage supply range and MSL rating
• Equivalent regulatory classification (ECCN and HTSUS codes)
• Active production status ensuring component availability
• RoHS compliance certification on the substitute part

The primary operational difference is the reduced operating distance specification (750 ft versus 1000 ft). System designs must account for this parameter variance when transitioning from the original to the substitute component.

Frequently Asked Questions (FAQ)

Q: Can CMD-HHCP-433-MD directly replace CMD-HHCP-433 in existing designs?

A: Yes. Both parts share identical frequency (433MHz), modulation protocol (ASK/OOK), voltage supply range (2.1V ~ 3.6V), and 8-button handheld interface. The operating distance specification differs (750 ft versus 1000 ft), which must be evaluated against system requirements.

Q: What is the primary reason for substitution?

A: The CMD-HHCP-433 is obsolete. The CMD-HHCP-433-MD is the active production equivalent from the same manufacturer.

Q: Are there packaging differences between these parts?

A: The substitute part is specified in bulk packaging. Original packaging specifications for CMD-HHCP-433 were not provided in the technical data.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts share identical ECCN (5A991G) and HTSUS (8525.50.3040) classifications. The substitute part additionally carries RoHS compliance certification.

Q: What is the moisture sensitivity level for both parts?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
