Key Parameters

Substitute Part Grouping Explanation

Substitution of the RM024-P125-M-30 is determined by strict electrical and mechanical parameter matching within the allowed specifications for ISM > 1GHz transceiver modules. The critical parameters governing substitution are:

Electrical Compatibility Parameters:

• RF Family/Standard: General ISM > 1GHz
• Protocol: RAMP
• Frequency: 2.4GHz
• Modulation: FHSS, MSK
• Data Rate: 500kbps
• Power Output: 21dBm
• Sensitivity: -95dBm
• Voltage Supply Range: 2.3V ~ 3.6V
• Current Specifications: Receiving 36mA, Transmitting 40mA ~ 136mA
• Serial Interface: UART

Mechanical Compatibility Parameters:

• Mounting Type: Through Hole
• Operating Temperature: -40°C ~ 85°C
• Package Type: Module

Antenna Configuration: The primary difference between the main part and its substitute relates to antenna type. The RM024-P125-M-30 features an integrated chip antenna, while the substitute RM024-P125-C-30 uses a U.FL connector with antenna not included. Both configurations maintain identical RF performance specifications and are electrically interchangeable when antenna requirements are addressed in the system design.

Parameter Comparison

Engineering Selection Recommendations

The RM024-P125-C-30 is the direct electrical substitute for the obsolete RM024-P125-M-30. Both parts share identical RF performance specifications, protocol support, and electrical characteristics across all critical parameters including frequency, modulation, data rate, power output, and sensitivity.

Product Status Consideration: The RM024-P125-M-30 is classified as Obsolete, while the RM024-P125-C-30 is Active. For new designs and ongoing production, the RM024-P125-C-30 is the appropriate selection to ensure long-term component availability and supply chain continuity.

Compliance and Certification: Both parts are RoHS Compliant and classified under ECCN EAR99. The RM024-P125-C-30 carries REACH Unaffected status, confirming regulatory compliance for European markets.

Antenna Configuration Impact: The primary design consideration is antenna implementation. The RM024-P125-M-30 includes an integrated chip antenna requiring no external antenna component. The RM024-P125-C-30 provides a U.FL connector interface with antenna not included, requiring external antenna selection and integration. System designers must account for this difference in PCB layout, antenna selection, and RF performance tuning.

Moisture Sensitivity: The RM024-P125-M-30 has MSL 1 (Unlimited), while the RM024-P125-C-30 has MSL 3 (168 Hours). Storage and handling procedures must reflect the higher moisture sensitivity of the substitute part.

Frequently Asked Questions (FAQ)

Q: Are the RM024-P125-M-30 and RM024-P125-C-30 electrically interchangeable?

A: Yes. Both parts operate at 2.4GHz with identical RF specifications including 21dBm output power, -95dBm sensitivity, 500kbps data rate, and FHSS/MSK modulation support. Electrical performance is equivalent across all UART serial interface, voltage supply, and current consumption parameters.

Q: What is the primary difference between these two parts?

A: The antenna configuration differs. The RM024-P125-M-30 integrates a chip antenna on the module. The RM024-P125-C-30 provides a U.FL connector interface without an integrated antenna, requiring external antenna selection and integration into the system design.

Q: Can I use the RM024-P125-C-30 as a direct replacement for the RM024-P125-M-30 in existing designs?

A: Electrical substitution is valid. However, PCB layout modifications are required to accommodate the U.FL connector interface and external antenna integration. RF performance tuning may be necessary depending on the external antenna selection and placement.

Q: Why is the RM024-P125-M-30 marked as Obsolete?

A: The RM024-P125-M-30 is no longer in active production. The RM024-P125-C-30 represents the current active product line from Laird Connectivity Inc. for this RF transceiver module family.

Q: What are the moisture sensitivity differences?

A: The RM024-P125-M-30 has MSL 1 (Unlimited moisture exposure allowed). The RM024-P125-C-30 has MSL 3 (168 hours maximum exposure before reflow). Storage conditions and handling procedures must account for the higher moisture sensitivity of the substitute part.

Q: Are both parts RoHS compliant?

A: Yes. Both the RM024-P125-M-30 and RM024-P125-C-30 are RoHS Compliant. The RM024-P125-C-30 additionally carries REACH Unaffected certification.

Q: What is the base product number for these modules?

A: The base product number is RM024-P125. The suffix designates specific configurations: -M-30 for the integrated chip antenna version and -C-30 for the U.FL connector version.
