Substitute Part Grouping Explanation

The RFM75P from RF Solutions qualifies as a functional substitute for the AW24MCHL-SM based on the following critical parameters:

Matching Criteria:

• RF Family/Standard: Both operate in the General ISM > 1GHz band
• Frequency: Both support 2.4GHz operation (RFM75P extends to 2.483GHz)
• Serial Interface: Both utilize SPI for communication
• Mounting Type: Both are surface mount configurations
• Output Power: Both deliver 4dBm
• Antenna Integration: Both feature integrated antenna designs

Substitution Logic: The RFM75P maintains electrical compatibility through matching output power, SPI interface protocol, and supply voltage overlap (1.9V ~ 3.6V encompasses the AW24MCHL-SM range of 2.4V ~ 3.6V). Both modules operate within the same ISM frequency band and support integrated antenna configurations, enabling direct functional replacement in system designs.

Engineering Selection Recommendations

The RFM75P is the identified substitute for the obsolete AW24MCHL-SM. Selection should be based on the following factors:

Product Status: The RFM75P maintains active product status with RF Solutions, ensuring ongoing availability and support. The AW24MCHL-SM is obsolete, making the RFM75P the appropriate choice for new designs and component replenishment.

Compliance & Certifications: The RFM75P holds ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements. Both modules share identical ECCN classification (5A991G), maintaining export control consistency.

Operational Parameters: The RFM75P delivers superior current efficiency in both receive (16.5mA vs. 18.4mA ~ 21.2mA) and transmit modes (18mA vs. 20.8mA ~ 34.1mA), with extended operating temperature range (-40°C ~ 85°C vs. -20°C ~ 70°C). The RFM75P supports doubled data rate capability (2Mbps vs. 1Mbps) while maintaining identical output power and SPI interface compatibility.

Moisture Sensitivity: The RFM75P features MSL 1 (Unlimited) compared to the AW24MCHL-SM MSL 3 (168 Hours), providing superior moisture tolerance for storage and handling.

Frequently Asked Questions (FAQ)

Q: Can the RFM75P directly replace the AW24MCHL-SM in existing designs?

A: Yes. Both modules operate at 2.4GHz, utilize SPI serial interface, deliver 4dBm output power, and feature integrated antenna designs. Surface mount mounting compatibility is maintained. Electrical parameter overlap in supply voltage (1.9V ~ 3.6V for RFM75P encompasses 2.4V ~ 3.6V for AW24MCHL-SM) supports direct substitution.

Q: What are the key differences between these modules?

A: The RFM75P offers improved current efficiency, extended operating temperature range (-40°C ~ 85°C vs. -20°C ~ 70°C), doubled data rate capability (2Mbps vs. 1Mbps), and superior moisture sensitivity rating (MSL 1 vs. MSL 3). The antenna implementation differs (trace-based vs. chip-based), though both are integrated designs.

Q: Are there any modulation differences to consider?

A: The AW24MCHL-SM supports both DSSS and GFSK modulation, while the RFM75P supports GFSK only. System designs utilizing DSSS modulation require evaluation of protocol compatibility with the RFM75P's GFSK-only capability.

Q: How do the sensitivity specifications compare?

A: The AW24MCHL-SM achieves -97dBm sensitivity versus -96dBm for the RFM75P, representing a 1dB difference. This minor variance is within typical system margin tolerances for ISM band applications.

Q: What packaging considerations apply to this substitution?

A: Both modules are surface mount configurations. The AW24MCHL-SM uses PCB Module packaging while the RFM75P uses Module packaging. Physical footprint and pinout compatibility must be verified against specific board layout requirements before implementation.
