Equivalent & Substitute Parts for Renesas 8308AGILF

Part Overview

The Renesas 8308AGILF is a Clock Fanout Buffer (Distribution) Multiplexer IC with a 2:8 input-to-output ratio, designed for clock distribution applications up to 350 MHz. This device features multiple input signal compatibility (HCSL, LVCMOS, LVDS, LVHSTL, LVPECL, LVTTL, SSTL) and LVCMOS/LVTTL output options in a 24-TSSOP surface mount package.

The 8308AGILF is classified as Obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for legacy systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 8308AGILF is determined by the following critical parameters:

• Input-to-Output Ratio: 2:8 configuration maintained across substitute parts
• Supply Voltage Range: 2.375V ~ 3.465V compatibility required
• Operating Temperature Range: -40°C ~ 85°C maintained
• Mounting Type: Surface mount technology required
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status required

The substitute part 8SLVP1208ANBGI maintains the 2:8 ratio and identical supply voltage and temperature specifications. While the substitute operates at higher maximum frequency (2 GHz versus 350 MHz) and uses a different package format (28-WFQFN versus 24-TSSOP), it satisfies the core functional and electrical requirements for clock distribution applications. The higher frequency capability of the substitute provides additional performance margin for legacy system implementations.

Parameter Comparison

Engineering Selection Recommendations

The 8SLVP1208ANBGI is the manufacturer-recommended substitute for the obsolete 8308AGILF. Both parts maintain identical supply voltage specifications (2.375V ~ 3.465V) and operating temperature range (-40°C ~ 85°C), ensuring direct functional compatibility in legacy system designs.

The substitute part carries Active product status, ensuring long-term availability and supply chain continuity. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current manufacturing and deployment.

The package change from 24-TSSOP to 28-WFQFN requires PCB layout modification. The substitute's higher maximum frequency (2 GHz) exceeds the original specification, providing performance margin for clock distribution applications. Input and output signal compatibility differences require circuit-level evaluation during design transition.

Frequently Asked Questions (FAQ)

Q: Can the 8SLVP1208ANBGI directly replace the 8308AGILF without circuit modifications?

A: The substitute maintains identical supply voltage and operating temperature specifications. However, the package format differs (24-TSSOP to 28-WFQFN), requiring PCB layout changes. Input signal types (CML, LVDS, LVPECL for substitute versus HCSL, LVCMOS, LVDS, LVHSTL, LVPECL, LVTTL, SSTL for original) and output signal types (LVPECL for substitute versus LVCMOS, LVTTL for original) must be evaluated for circuit compatibility.

Q: What is the significance of the package change from 24-TSSOP to 28-WFQFN?

A: The 24-TSSOP measures 0.173" × 4.40mm width, while the 28-WFQFN is a 5×5mm footprint. This represents a different physical form factor requiring PCB redesign, including trace routing, via placement, and thermal management considerations. The WFQFN package includes an exposed pad for improved thermal performance.

Q: Why does the substitute part have a higher maximum frequency specification?

A: The 8SLVP1208ANBGI operates at 2 GHz maximum frequency compared to the 350 MHz specification of the 8308AGILF. This higher capability does not affect compatibility with 350 MHz clock distribution applications; it indicates enhanced performance margin and broader application support in the substitute design.

Q: Are both parts compliant with current regulatory standards?

A: Both the 8308AGILF and 8SLVP1208ANBGI are ROHS3 compliant and REACH unaffected. The substitute carries Active product status, ensuring compliance maintenance and long-term regulatory support.

Q: What inventory considerations apply to this substitution?

A: The 8308AGILF (Obsolete) has 6110 pieces in stock. The 8SLVP1208ANBGI (Active) has 2276 pieces available. For new designs or production continuation, the Active substitute part ensures ongoing supply availability beyond current inventory levels.
