Key Parameters

Substitute Part Grouping Explanation

Substitution of the 83058AGILF is determined by the following critical parameters:

Functional Compatibility:

• Input:Output ratio of 8:1 (mandatory for direct functional replacement)
• Multiplexer topology and circuit count (1 circuit)
• Surface mount packaging with compatible footprint dimensions

Electrical Compatibility:

• Operating temperature range: -40°C to 85°C (required match)
• Supply voltage overlap within specified ranges
• Signal level compatibility (input and output types)
• Frequency capability sufficient for application requirements

Regulatory & Environmental Compliance:

• RoHS3 compliance status
• Moisture sensitivity level classification
• REACH compliance status

The substitute part 854S058AGILF maintains the 8:1 multiplexer ratio and core functional architecture while introducing enhanced frequency capability (2.5 GHz versus 250 MHz) and differential signal support. Both parts share identical operating temperature ranges, RoHS3 compliance, and MSL ratings, establishing a valid substitution pathway for applications requiring higher frequency operation or differential signal processing.

Parameter Comparison

Engineering Selection Recommendations

The 854S058AGILF represents an active product alternative to the obsolete 83058AGILF, with both components manufactured by Renesas Electronics Corporation and maintaining identical compliance certifications (RoHS3, REACH Unaffected, MSL 1).

Key Considerations for Selection:

The substitute part introduces a package change from 16-TSSOP to 24-TSSOP, requiring PCB layout modification. The minimum supply voltage requirement increases from 2.375V to 3.135V, necessitating verification of power supply specifications in existing designs.

Signal level architecture differs fundamentally: the 83058AGILF operates with single-ended LVCMOS/LVTTL signals, while the 854S058AGILF employs differential LVDS output with multi-format input support (LVDS, LVPECL, SSTL). This architectural change requires signal conditioning circuit evaluation.

The frequency capability increase from 250 MHz to 2.5 GHz provides extended operational headroom for future applications, though this enhancement is not required for direct replacement of 250 MHz clock distribution functions.

Both components share identical operating temperature specifications (-40°C to 85°C) and moisture sensitivity classifications, ensuring thermal and environmental compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 854S058AGILF directly replace the 83058AGILF in existing designs?

A: Direct replacement requires PCB layout modification due to package change from 16-TSSOP to 24-TSSOP. Additionally, signal level conversion circuitry must be evaluated, as the substitute part uses differential LVDS output versus single-ended LVCMOS/LVTTL output in the original part.

Q: What is the primary reason for seeking a substitute for the 83058AGILF?

A: The 83058AGILF is classified as obsolete. The 854S058AGILF is an active product from the same manufacturer, ensuring continued availability and supply chain stability.

Q: Are the operating temperature ranges compatible?

A: Yes. Both the 83058AGILF and 854S058AGILF operate across the identical temperature range of -40°C to 85°C, ensuring thermal compatibility in industrial applications.

Q: What is the impact of the supply voltage change from 2.375V minimum to 3.135V minimum?

A: Systems operating at supply voltages below 3.135V cannot use the 854S058AGILF. Existing power supply specifications must be verified to confirm compatibility with the substitute part's minimum voltage requirement.

Q: How does the package change from 16-TSSOP to 24-TSSOP affect implementation?

A: The 24-TSSOP package is physically larger and requires different PCB footprint design. Existing circuit board layouts cannot accommodate this package without redesign. Both packages maintain the same 0.173" width specification.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the 83058AGILF and 854S058AGILF are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the significance of the differential signal support in the 854S058AGILF?

A: The 854S058AGILF supports differential input (LVDS, LVPECL, SSTL) and differential output (LVDS), enabling operation in high-speed, noise-sensitive applications. The original 83058AGILF supports only single-ended signals. Signal conditioning circuits must be designed accordingly for each application.
