Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RM024-S125-M-30 is determined by strict equivalence across the following critical parameters:

RF Performance Parameters: RF Family/Standard (General ISM > 1GHz), Protocol (RAMP), Modulation (FHSS, MSK), Frequency (2.4GHz), Data Rate (500kbps), Power Output (21dBm), and Sensitivity (-95dBm) must remain identical.

Electrical Parameters: Voltage Supply range (2.3V ~ 3.6V), Current Receiving (36mA), and Current Transmitting (40mA ~ 136mA) must match exactly.

Physical & Environmental Parameters: Mounting Type (Surface Mount), Operating Temperature range (-40°C ~ 85°C), Package classification (Module), and MSL rating (3, 168 Hours) must be equivalent.

Interface & Compliance: Serial Interfaces (UART), RoHS Compliance status, and base manufacturer (Laird Connectivity Inc.) establish substitution boundaries.

The primary distinction between the main part and substitute parts lies in Antenna Type configuration and Product Status. The RM024-S125-M-30 features an integrated chip antenna, while substitute variants may employ external antenna connectors (U.FL) or different antenna implementations. This distinction does not affect RF performance parameters but impacts physical integration and design flexibility.

Parameter Comparison

Engineering Selection Recommendations

RM024-S125-C-30 is the primary substitute for RM024-S125-M-30. Both parts share identical RF performance, electrical characteristics, and environmental operating parameters. The RM024-S125-C-30 maintains Active product status, ensuring ongoing manufacturer support and supply chain availability. Both parts carry RoHS Compliance certification and equivalent MSL ratings.

The functional distinction between these parts is the antenna configuration. The RM024-S125-M-30 integrates a chip antenna within the module, while the RM024-S125-C-30 provides a U.FL connector for external antenna attachment. This difference affects physical PCB layout and antenna tuning but does not alter transceiver RF performance specifications.

Selection of RM024-S125-C-30 is appropriate for applications where:

• Existing designs can accommodate external antenna connector integration
• Design flexibility for antenna selection and placement is required
• Supply continuity for an Active product is prioritized over the Obsolete RM024-S125-M-30
• Compliance certifications (RoHS, MSL) are maintained at equivalent levels

Both parts are manufactured by Laird Connectivity Inc. and share the common base product number RM024-S125, confirming architectural compatibility within the product family.

Frequently Asked Questions (FAQ)

Q: Can RM024-S125-C-30 directly replace RM024-S125-M-30 in existing designs?

A: RM024-S125-C-30 is electrically and functionally equivalent to RM024-S125-M-30 across all RF performance and electrical parameters. However, the antenna configuration differs. RM024-S125-M-30 features an integrated chip antenna, while RM024-S125-C-30 requires external antenna connection via U.FL connector. PCB layout modifications are necessary to accommodate the external antenna interface.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by equivalence in RF Family/Standard (General ISM > 1GHz), Protocol (RAMP), Modulation (FHSS, MSK), Frequency (2.4GHz), Data Rate (500kbps), Power Output (21dBm), Sensitivity (-95dBm), Voltage Supply (2.3V ~ 3.6V), Current specifications, Mounting Type (Surface Mount), Operating Temperature (-40°C ~ 85°C), and compliance certifications (RoHS, MSL).

Q: Why is RM024-S125-M-30 classified as Obsolete?

A: The RM024-S125-M-30 is listed as Obsolete by the manufacturer. RM024-S125-C-30 maintains Active status, indicating ongoing production and manufacturer support. For new designs or continued production, RM024-S125-C-30 is the recommended selection.

Q: Are there compliance or certification differences between these parts?

A: Both RM024-S125-M-30 and RM024-S125-C-30 are RoHS Compliant with identical MSL ratings (3, 168 Hours). RM024-S125-C-30 carries REACH Unaffected status. Compliance certifications are equivalent across both parts.

Q: What is the impact of antenna type on system performance?

A: The antenna type (integrated chip vs. external U.FL) affects physical integration and antenna tuning flexibility but does not alter the transceiver module's RF performance specifications. Both configurations deliver identical output power (21dBm) and sensitivity (-95dBm) when properly integrated.

Q: What packaging differences exist between these parts?

A: RM024-S125-M-30 packaging is listed as "-" (unspecified). RM024-S125-C-30 is supplied in Tray packaging. This distinction affects handling and storage but does not impact electrical or RF performance.
