SL23EP04SC-2H Equivalent & Substitute Parts

Part Overview

The SL23EP04SC-2H is a clock buffer IC manufactured by Skyworks Solutions Inc., designed for 220MHz clock distribution applications. This device features a 1:4 input-to-output ratio with LVCMOS output configuration in an 8-SOIC package. The product is currently obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SL23EP04SC-2H is determined by the following critical parameters:

• Maximum frequency capability (220 MHz minimum required)
• Input-to-output ratio (1:4 configuration)
• Output signal type (LVCMOS)
• Supply voltage compatibility (3.3V nominal operation)
• Package form factor and mounting type (surface mount)

The SI53365-B-GT qualifies as a functional substitute based on shared manufacturer origin, compatible output type (LVCMOS), overlapping supply voltage range, and surface mount configuration. However, differences in frequency rating, output ratio, and package type must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The SI53365-B-GT is an active product from the same manufacturer, providing extended product lifecycle support compared to the obsolete SL23EP04SC-2H. The substitute demonstrates improved compliance status with ROHS3 certification and extended moisture sensitivity rating (1 Year versus 4 Weeks).

Key considerations for substitution:

• The SI53365-B-GT operates at 200 MHz maximum frequency, which is 20 MHz below the original part specification
• The output ratio differs (1:8 versus 1:4), requiring circuit-level evaluation for compatibility
• Package transition from 8-SOIC to 16-TSSOP necessitates PCB layout modifications
• Supply voltage range of the substitute (1.71V ~ 3.63V) encompasses the original specification (2.97V ~ 3.63V)
• Operating temperature range expansion (-40°C ~ 85°C) provides broader environmental coverage

Frequently Asked Questions (FAQ)

Q: Can the SI53365-B-GT directly replace the SL23EP04SC-2H without circuit modifications?

A: Direct replacement is not possible due to package differences (8-SOIC versus 16-TSSOP), different output ratios (1:4 versus 1:8), and frequency specification variance. PCB layout redesign and circuit evaluation are required.

Q: What is the impact of the 1:8 output ratio on system design?

A: The SI53365-B-GT provides eight output channels compared to four on the original part. System design must accommodate the additional outputs through proper termination or signal routing.

Q: Does the 200 MHz frequency rating of the SI53365-B-GT meet application requirements?

A: Applications requiring operation above 200 MHz cannot use this substitute. Frequency margin analysis specific to your system clock specifications is necessary.

Q: Are there package compatibility considerations?

A: Yes. The transition from 8-SOIC to 16-TSSOP requires PCB redesign, including new footprint layout, trace routing, and potentially different power distribution strategies due to increased pin count.

Q: What compliance advantages does the SI53365-B-GT offer?

A: The substitute provides ROHS3 compliance and extended moisture sensitivity rating (1 Year), supporting modern supply chain and storage requirements compared to the obsolete original part.

Q: Is the supply voltage range of the SI53365-B-GT compatible with 3.3V systems?

A: Yes. The substitute supply voltage range (1.71V ~ 3.63V) fully encompasses standard 3.3V operation, maintaining compatibility with the original part's nominal supply voltage.
