Equivalent & Substitute Parts for Renesas 8304AMILF

Part Overview

The Renesas 8304AMILF is a Clock Fanout Buffer (Distribution) IC with a 1:4 input-to-output ratio, designed for clock distribution applications requiring up to 166 MHz frequency operation. This device features LVCMOS and LVTTL input/output compatibility and operates across a supply voltage range of 3.135V to 3.465V. The 8304AMILF is classified as obsolete, necessitating identification of functionally equivalent substitute components for new designs and ongoing production requirements. Substitute parts must maintain core functional parameters including the 1:4 fanout ratio, single-circuit configuration, and surface-mount packaging while meeting current product status and compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

Renesas 5PB1104CMGI: This substitute offers active product status with ROHS3 compliance. The 5PB1104CMGI provides superior frequency capability at 200 MHz, exceeding the 8304AMILF specification. Supply voltage range extends to 1.71V minimum, providing broader operational flexibility. Operating temperature range matches the original specification at -40°C to 85°C. Package form factor differs (8-UFDFN versus 8-SOIC), requiring PCB layout modification. Moisture sensitivity level is 1 (Unlimited), indicating superior moisture resistance compared to the original device. This option is suitable for applications requiring extended frequency headroom and modern compliance certifications.

Microchip PL133-47SI: This substitute maintains identical 8-SOIC package geometry to the 8304AMILF, eliminating PCB redesign requirements. Operating temperature range matches the original at -40°C to 85°C. ROHS3 compliance and REACH unaffected status satisfy modern regulatory requirements. Supply voltage range of 2.25V to 3.63V encompasses the original 3.135V to 3.465V specification. Frequency specification of 150 MHz is below the original 166 MHz, suitable for applications not requiring maximum frequency operation. Active product status ensures long-term availability. This option provides direct form-factor compatibility with minimal design modification.

Microchip PL133-47SC and PL133-47SC-R: Both variants maintain 8-SOIC package compatibility and ROHS3 compliance. The primary distinction is packaging format: PL133-47SC is supplied in tubes, while PL133-47SC-R is supplied in tape and reel format. Operating temperature range for PL133-47SC is limited to 0°C to 70°C, restricting use in applications requiring full -40°C to 85°C operation. PL133-47SC-R maintains identical electrical specifications to PL133-47SC. Both parts are suitable for commercial-grade applications with standard temperature requirements and high-volume production scenarios.

Frequently Asked Questions (FAQ)

Q: Can the 5PB1104CMGI substitute for the 8304AMILF in existing designs without modification?

A: The 5PB1104CMGI maintains functional equivalence in fanout buffer operation, 1:4 ratio, and single-circuit configuration. However, the package form factor differs (8-UFDFN versus 8-SOIC), requiring PCB layout and footprint modification. Electrical parameters are compatible within the specified operating ranges.

Q: What is the primary advantage of selecting a Microchip PL133 variant over the Renesas 5PB1104CMGI?

A: The Microchip PL133 series maintains identical 8-SOIC package geometry to the original 8304AMILF, eliminating PCB redesign requirements. This provides cost and schedule advantages for existing board designs. The 5PB1104CMGI offers higher frequency capability (200 MHz) and lower minimum supply voltage (1.71V) for applications requiring these enhanced specifications.

Q: Are all substitute parts RoHS compliant?

A: All identified substitute parts (5PB1104CMGI, PL133-47SC, PL133-47SC-R, and PL133-47SI) are ROHS3 compliant. The original 8304AMILF is RoHS non-compliant, making substitution necessary for applications subject to RoHS regulations.

Q: Which substitute part supports the full -40°C to 85°C operating temperature range?

A: The Renesas 5PB1104CMGI and Microchip PL133-47SI both support the full -40°C to 85°C operating temperature range. The Microchip PL133-47SC and PL133-47SC-R are limited to 0°C to 70°C operation.

Q: What is the difference between PL133-47SC and PL133-47SC-R?

A: Both parts are electrically identical with 150 MHz maximum frequency and 8-SOIC package. The primary difference is packaging format: PL133-47SC is supplied in tube packaging, while PL133-47SC-R is supplied in tape and reel format. Selection depends on production volume and assembly equipment compatibility.

Q: Does the 5PB1104CMGI require different PCB layout considerations compared to the 8304AMILF?

A: Yes. The 5PB1104CMGI uses an 8-UFDFN (2x2) package, which is physically smaller than the 8-SOIC package of the 8304AMILF. PCB footprint, trace routing, and via placement require modification to accommodate the different package geometry and pin configuration.

Q: Can the PL133-47SI be used in applications requiring 166 MHz operation?

A: The PL133-47SI has a maximum frequency specification of 150 MHz, which is below the 166 MHz requirement of the original 8304AMILF. This part is suitable only for applications operating at or below 150 MHz. For applications requiring 166 MHz or higher, the Renesas 5PB1104CMGI (200 MHz) is the appropriate selection.

Q: What supply voltage range is required for all substitute parts?

A: The Renesas 5PB1104CMGI operates from 1.71V to 3.465V. The Microchip PL133 variants operate from 2.25V to 3.63V. All ranges encompass the original 8304AMILF specification of 3.135V to 3.465V. Verify specific application supply voltage against each substitute's operating range.
