Key Parameters

Substitute Part Grouping Explanation

Substitution of the RFX242 is determined by strict alignment of the following critical parameters:

• Frequency Range: 2.4GHz ~ 2.5GHz operation
• RF Type: 802.11a/b/g/n/ac compatibility
• Gain: 32dB
• P1dB: 31dBm
• Supply Voltage: 5V
• Supply Current: 430mA
• Package: 16-QFN (3x3) with exposed pad
• Mounting Type: Surface Mount
• RoHS Compliance: ROHS3 Compliant

A part qualifies as a direct equivalent or substitute only when all electrical parameters (frequency, gain, P1dB, supply voltage, and current) and mechanical parameters (package type, mounting method) match the RFX242 specification. The RFX242 itself, as provided in the input data, meets all these criteria as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

The RFX242 is classified as obsolete. When sourcing this component, the following engineering considerations apply:

Compliance & Certification: The RFX242 is ROHS3 compliant and carries an MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage and handling. These compliance attributes must be maintained in any substitute selection.

Product Status Impact: Obsolete status indicates the component is no longer manufactured. Sourcing decisions should prioritize available inventory from authorized distributors. The parametric equivalent RFX242 listed in this reference maintains identical electrical and mechanical specifications, ensuring direct functional compatibility in existing designs.

Supply Chain Continuity: For long-term production support, evaluate alternative RF amplifier ICs from Skyworks Solutions Inc. or other manufacturers that meet the specified electrical parameters (32dB gain, 31dBm P1dB, 5V supply, 430mA current) and mechanical requirements (16-QFN 3x3 package, surface mount).

Frequently Asked Questions (FAQ)

Q: Can the RFX242 be substituted with a different RF amplifier IC?

A: Direct substitution requires an alternative part that matches all specified parameters: 2.4GHz ~ 2.5GHz frequency range, 32dB gain, 31dBm P1dB, 5V supply voltage, 430mA supply current, and 16-QFN (3x3) surface mount package. Only parts meeting these exact specifications are considered equivalent.

Q: What does the obsolete status mean for the RFX242?

A: Obsolete status indicates the RFX242 is no longer in active production. Existing inventory may be available through authorized distributors, but long-term availability is not guaranteed. Design teams should evaluate alternative components or plan for redesign if future production quantities are required.

Q: Is the RFX242 RoHS compliant?

A: Yes, the RFX242 is ROHS3 compliant and carries an MSL rating of 1 (Unlimited), meeting environmental and moisture sensitivity requirements for standard manufacturing and assembly processes.

Q: What is the significance of the 16-QFN (3x3) package with exposed pad?

A: The 16-QFN (3x3) package with exposed pad is a surface mount configuration that provides thermal management and electrical performance suitable for RF amplifier applications. Any substitute part must use the identical package type to ensure PCB layout compatibility and thermal characteristics.

Q: Are there any supply chain alternatives for the RFX242?

A: The RFX242 is sourced exclusively from Skyworks Solutions Inc. For obsolete components, authorized distributors may hold remaining inventory. For new designs or long-term production, consult Skyworks Solutions Inc. for recommended alternative RF amplifier ICs that meet your application requirements.
