MM2-P-T Equivalent & Substitute Parts

Part Overview

The MM2-P-T is a General ISM < 1GHz transceiver module manufactured by FreeWave Technologies, operating in the 902MHz to 928MHz frequency band. This chassis-mount RF module is designed for applications requiring ISM band communication with GFSK modulation and TTL/Ethernet serial interfaces. The MM2-P-T is currently classified as obsolete, making identification of compatible substitute parts essential for system maintenance, redesign, and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MM2-P-T are identified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Frequency range: 902MHz ~ 928MHz ISM band operation
• Modulation type: GFSK
• Mounting configuration: Chassis Mount
• Serial interface capability: TTL or Ethernet connectivity
• Sensitivity level: -108dBm or better
• Operating temperature range: -40°C ~ 85°C minimum
• Manufacturer: FreeWave Technologies (same product family)

The MM3 series (MM3-P-T and MM3-T) meets these criteria as active, current-production alternatives within the FreeWave Technologies product line. Both substitute parts maintain the same frequency band, modulation standard, mounting type, and operating temperature specifications as the obsolete MM2-P-T.

Parameter Comparison

Engineering Selection Recommendations

MM3-T is the primary substitute for the MM2-P-T. Both modules share identical frequency range (902MHz ~ 928MHz), modulation (GFSK), sensitivity (-108dBm), mounting type (Chassis Mount), and operating temperature range (-40°C ~ 85°C). The MM3-T is an active product with current manufacturing status, ensuring long-term availability and supply chain stability. The MM3-T supports dual data rates (115.2kbps and 153.6kbps), providing operational flexibility. Current consumption during receive operation is reduced to 90mA compared to the MM2-P-T's 205mA, offering improved power efficiency. The supply voltage specification is tightened to 4.75V ~ 5.25V, requiring verification of system power delivery tolerance.

MM3-P-T is listed as a manufacturer-recommended substitute but lacks detailed electrical specifications in the provided data. This part should be evaluated only when MM3-T specifications do not align with system requirements or when specific interface requirements necessitate the MM3-P-T variant.

Both substitute parts maintain RoHS non-compliant status consistent with the original MM2-P-T, indicating no change in environmental compliance classification.

Frequently Asked Questions (FAQ)

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

A: The MM3-T maintains compatibility across all critical parameters: frequency band (902MHz ~ 928MHz), modulation (GFSK), sensitivity (-108dBm), mounting type (Chassis Mount), and operating temperature range (-40°C ~ 85°C). However, the supply voltage specification differs (MM2-P-T: 5V nominal vs. MM3-T: 4.75V ~ 5.25V). Verify that your system power supply operates within the MM3-T tolerance window. The MM3-T also features reduced receive current (90mA vs. 205mA), which may require power budget recalculation.

Q: What is the difference between MM3-P-T and MM3-T?

A: Both are active FreeWave Technologies products in the MM3 series. The MM3-T provides complete electrical specifications and is recommended for direct substitution. The MM3-P-T is listed as a manufacturer-recommended alternative but lacks detailed technical parameters in available documentation. Selection between these variants should be based on specific interface or packaging requirements not detailed in the provided specifications.

Q: Does the MM3-T support the same serial interfaces as the MM2-P-T?

A: The MM2-P-T supports both Ethernet and Serial TTL interfaces. The MM3-T supports Serial TTL only. If your application requires Ethernet connectivity, interface compatibility must be verified before substitution.

Q: Are there any compliance differences between the MM2-P-T and MM3-T?

A: Both parts maintain RoHS non-compliant status and share identical ECCN (5A002A FWT) and HTSUS (8517.62.0090) classifications. The MM3-T specifies Moisture Sensitivity Level 1 (Unlimited), whereas the MM2-P-T lists MSL as Not Applicable. This difference reflects updated component handling standards but does not affect electrical performance.

Q: What is the antenna configuration for the MM3-T?

A: The MM3-T is supplied with antenna not included. Verify that your system design accommodates external antenna integration or sourcing.
