Key Parameters

Substitute Part Grouping Explanation

The MM3-T qualifies as a direct substitute for the MM2-T based on the following critical parameters:

Frequency Compatibility: Both modules operate within the identical 902MHz to 928MHz ISM band, ensuring RF performance alignment for existing system designs.

Modulation & Interface: Both employ GFSK modulation and Serial TTL interfaces, maintaining signal processing and communication protocol compatibility.

Sensitivity & Power Characteristics: Matching receiver sensitivity of -108dBm and identical current consumption specifications (90mA receive, 855mA transmit) ensure equivalent power budget and link performance.

Mechanical & Thermal Specifications: Both modules feature chassis mount configuration and identical operating temperature range (-40°C to 85°C), supporting equivalent mechanical integration and environmental performance.

Regulatory Compliance: Both modules share identical ECCN and HTSUS classifications, confirming equivalent export control and tariff treatment.

Parameter Comparison

Engineering Selection Recommendations

The MM3-T is the designated substitute for the obsolete MM2-T based on functional and regulatory equivalence. The MM3-T maintains active product status with FreeWave Technologies, ensuring continued availability and technical support.

The primary design consideration is antenna configuration: the MM2-T features an integrated chip antenna, while the MM3-T requires external antenna integration. System designs utilizing the MM2-T must accommodate external antenna selection and impedance matching when transitioning to the MM3-T.

Voltage supply specifications show the MM3-T accepts a wider tolerance range (4.75V to 5.25V) compared to the MM2-T nominal 5V specification, providing enhanced flexibility in power supply design.

Both modules maintain identical RoHS non-compliant status and share equivalent export control classifications (ECCN 5A002A FWT, HTSUS 8517.62.0090).

Frequently Asked Questions (FAQ)

Q: Can the MM3-T directly replace the MM2-T in existing designs?

A: The MM3-T provides functional RF equivalence for the MM2-T. The primary design modification required is external antenna integration, as the MM2-T includes an integrated chip antenna while the MM3-T does not. All RF performance parameters, power consumption, and interface specifications remain equivalent.

Q: What are the key differences between these modules?

A: The MM3-T supports dual data rates (115.2kbps and 153.6kbps) compared to the MM2-T single rate of 153.6kbps. The MM3-T also features expanded voltage supply tolerance (4.75V to 5.25V) versus the MM2-T nominal 5V. Antenna configuration differs: integrated chip antenna on MM2-T versus external antenna requirement on MM3-T.

Q: Are there any compliance or regulatory differences?

A: Both modules share identical ECCN and HTSUS classifications, confirming equivalent regulatory treatment. Both maintain RoHS non-compliant status.

Q: What packaging options are available?

A: The MM2-T is supplied in module packaging. The MM3-T is supplied in box packaging with 907 pieces currently in stock.

Q: How do the power consumption specifications compare?

A: Both modules consume 90mA during receive operation and 855mA during transmit operation, providing identical power budget requirements for system design.
