SE2548A-R Equivalent & Substitute Parts

Part Overview

The SE2548A-R is an RF IC front end module manufactured by Skyworks Solutions Inc., designed for 802.11a/b/g/n wireless applications. This component integrates front-end functionality for dual-band operation across 2.4GHz–2.5GHz and 4.9GHz–5.875GHz frequency ranges in a 32-LGA (5x5) surface mount package. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for legacy system maintenance, redesign initiatives, and continued component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SE2548A-R is determined by the following critical parameters:

• RF Type & Frequency Coverage: Substitute parts must support 802.11a/b/g/n standards with identical frequency ranges (2.4GHz–2.5GHz and 4.9GHz–5.875GHz)
• Function Classification: Front-end functionality must be maintained
• Package Compatibility: Physical dimensions and pin count must accommodate PCB layout constraints
• Compliance & Environmental Ratings: RoHS3 compliance and MSL rating must meet or exceed the original specification
• Manufacturer Series: Parts from the Skyworks Solutions SiGe series maintain design consistency

The SE2594L-R qualifies as a substitute based on matching RF type, frequency coverage, function, compliance status, and environmental ratings. The primary distinction is the package format: SE2594L-R uses 32-QFN (5x5) versus the original 32-LGA (5x5), requiring PCB layout verification for pin-to-pin compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the SE2548A-R and SE2594L-R are classified as obsolete products. Selection between these parts should be based on:

• PCB Layout Compatibility: The package transition from 32-LGA to 32-QFN requires verification of pin assignments and footprint compatibility. Both packages maintain 5x5mm dimensions but differ in lead configuration (land grid array versus quad flat no-lead).
• Compliance Alignment: Both parts meet ROHS3 compliance and identical MSL ratings, ensuring environmental and regulatory compatibility.
• Frequency & RF Specification Match: Identical 802.11a/b/g/n support and frequency coverage (2.4GHz–2.5GHz, 4.9GHz–5.875GHz) confirm functional equivalence.
• Inventory Availability: SE2594L-R shows higher inventory availability (20,200 pcs vs. 8,142 pcs), which may influence sourcing decisions for volume requirements.

Frequently Asked Questions (FAQ)

Q: Can SE2594L-R directly replace SE2548A-R without PCB modifications?

A: Both parts share identical frequency coverage, RF type, and functional classification. However, the package format differs (32-LGA versus 32-QFN). Direct replacement requires confirmation that pin assignments align with existing PCB footprints. Consult component datasheets for detailed pinout verification.

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

A: No. Both parts are ROHS3 compliant with identical MSL ratings of 3 (168 Hours), ensuring equivalent environmental performance and regulatory compliance.

Q: Why is the SE2548A-R classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. This necessitates sourcing from existing inventory or identifying functional equivalents for ongoing system support and new designs.

Q: What determines substitution eligibility for 802.11a/b/g/n front-end modules?

A: Substitution requires matching RF type, frequency range coverage, front-end function, package pin count, and compliance certifications. Package format differences (LGA versus QFN) require PCB layout verification but do not preclude substitution if pinout compatibility is confirmed.

Q: Are there other Skyworks SiGe front-end parts compatible with this application?

A: Substitution is limited to parts meeting all specified parameters: 802.11a/b/g/n support, 2.4GHz–2.5GHz and 4.9GHz–5.875GHz frequency ranges, front-end function, 32-pin surface mount package, ROHS3 compliance, and MSL 3 rating. Only SE2594L-R meets these criteria based on provided data.
