SE2574BL-RC RF Amplifier IC Equivalent & Substitute Parts

Part Overview

The SE2574BL-RC is an RF amplifier integrated circuit designed for 802.11b/g/n WLAN applications operating in the 2.4GHz to 2.5GHz frequency band. This component is classified as obsolete, which necessitates identification of active equivalent parts for ongoing design support and procurement. The SE2574BL-RC delivers 29dB gain with a 25dBm P1dB compression point, operating from a 2.7V to 5V supply with 165mA typical current consumption in an 8-QFN surface mount package.

Key Parameters

Substitute Part Grouping Explanation

The SE2574BL-R qualifies as a parametric equivalent to the SE2574BL-RC based on identical electrical and mechanical specifications. Both parts share the same base product number (SE2574), frequency range (2.4GHz ~ 2.5GHz), gain (29dB), P1dB (25dBm), supply voltage range (2.7V ~ 5V), supply current (165mA), RF type (802.11b/g/n WLAN), and package configuration (8-VFDFN Exposed Pad, 8-QFN 2x2). The primary distinction is product status: SE2574BL-RC is obsolete while SE2574BL-R maintains active production status. Packaging format differs (SE2574BL-RC is loose, SE2574BL-R is supplied in Tape & Reel format), and compliance certifications vary accordingly.

Parameter Comparison

Engineering Selection Recommendations

The SE2574BL-R is the direct active equivalent for the obsolete SE2574BL-RC. Both parts are manufactured by Skyworks Solutions Inc. and maintain identical electrical performance across all specified parameters including frequency response, gain, compression point, and power supply requirements. The SE2574BL-R is RoHS compliant and carries an MSL rating of 1 (Unlimited), indicating superior moisture handling characteristics. For new designs or ongoing production requiring 802.11b/g/n WLAN RF amplification in the 2.4GHz band, the SE2574BL-R should be selected. Existing inventory of SE2574BL-RC may be utilized in current production runs, but procurement should transition to SE2574BL-R for supply chain continuity. The Tape & Reel packaging of SE2574BL-R is standard for automated assembly processes and provides better handling protection compared to loose packaging.

Frequently Asked Questions (FAQ)

Q: Can SE2574BL-R directly replace SE2574BL-RC in existing designs? A: Yes. Both parts are electrically and mechanically identical across all specified parameters. No circuit modifications are required for substitution.
