Equivalent & Substitute Parts Reference: MM2-T-RX

Part Overview

The MM2-T-RX from FreeWave Technologies is an RF transceiver module designed for General ISM applications operating below 1GHz, specifically within the 902MHz to 928MHz frequency range. It features GFSK modulation, a Serial TTL interface, integrated chip antenna, and chassis mount assembly. This module is currently classified as obsolete, necessitating the identification of alternate or substitute models to ensure continuity in applications requiring similar electrical and mechanical properties.

Substitute Part Grouping Explanation

Substitute parts for the MM2-T-RX are grouped strictly according to the parameters above. The acceptable substitutes must match the following:

• Manufacturer: FreeWave Technologies
• RF Family/Standard: General ISM < 1GHz or equivalent
• Modulation: GFSK
• Frequency: 902MHz ~ 928MHz
• Data Rate: 153.6kbps (with allowance for equal or higher data rate if explicitly listed)
• Sensitivity: -108dBm
• Serial Interfaces: Serial TTL
• Antenna Type: Integrated, Chip or compatible mounting; differences in antenna inclusion are noted.
• Voltage Supply: 5V (allowable range if stated)
• Current (Receiving/Transmitting): 90mA / 855mA
• Mounting Type: Chassis Mount
• Operating Temperature: -40°C ~ 85°C
• Package / Case: Module
• RoHS Status: RoHS non-compliant

Only parts sharing these parameters are included as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The MM2-T-RX is currently classified as obsolete, while the MM3-T substitute is active. Both parts have RoHS non-compliant status, maintain identical electrical ratings (modulation type, RF frequency range, data rate, sensitivity, voltage/current requirements), and support the identical operating temperature range and chassis mount module package. The difference in antenna type must be considered for system-level installation; MM3-T does not include an integrated antenna. Only product status, RoHS status, and listed certifications are provided and must be used directly for selection.

Frequently Asked Questions (FAQ)

Q1: What are the critical selection criteria for substituting MM2-T-RX with MM3-T?
A1: Substitute selection is based strictly on matching modulation, frequency range, serial interface, data rate, sensitivity, voltage supply, current requirements, mounting type, package type, operating temperature range, and RoHS status.

Q2: Does a difference in antenna inclusion affect substitution?
A2: MM2-T-RX includes an integrated chip antenna, whereas MM3-T does not. This affects physical integration and must be considered based on system requirements.

Q3: Are voltage supply tolerances or ranges acceptable for substitution?
A3: MM3-T specifies a voltage supply range (4.75V ~ 5.25V) which includes the fixed 5V value for MM2-T-RX. Substitution is suitable within this documented range.

Q4: Is package compatibility between MM2-T-RX and MM3-T maintained?
A4: Both parts have a chassis mount module package, ensuring mechanical compatibility.

Q5: Are there differences in compliance or certification that limit substitution?
A5: Both parts are documented as RoHS non-compliant and have the same ECCN classification; substitution does not alter compliance status.
