PI6C48533-01LEX Equivalent & Substitute Parts

Part Overview

The PI6C48533-01LEX is a Clock Fanout Buffer (Distribution) Multiplexer IC manufactured by Diodes Incorporated, designed for 2:4 clock distribution at 800 MHz with differential input and output support. This part is classified as Obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. The part operates across a 3V to 3.6V supply range and supports multiple input standards including CML, HCSL, LVDS, LVHSTL, LVPECL, and SSTL, with LVPECL output.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the PI6C48533-01LEX is based on the following critical parameters that must remain consistent:

• Package Type: 20-TSSOP (0.173", 4.40mm Width) — physical and electrical compatibility requirement
• Input:Output Ratio: 2:4 — functional equivalence for clock distribution topology
• Differential Support: Yes/Yes for both input and output — signal integrity requirement
• Input Standards: CML, HCSL, LVDS, LVHSTL, LVPECL, SSTL — interface compatibility
• Output Standard: LVPECL — downstream circuit compatibility
• Mounting Type: Surface Mount — PCB assembly compatibility
• RoHS3 Compliance: Required for regulatory alignment

The substitute parts from Renesas Electronics Corporation (8533A series) maintain all critical parameters. The primary difference is the maximum frequency specification: substitute parts operate at 650 MHz versus the original 800 MHz. This represents a functional limitation that must be evaluated against application requirements. Substitute parts are available in Active product status with multiple packaging options (Tube and Cut Tape & Digi-Reel®).

Parameter Comparison

Engineering Selection Recommendations

Frequency Derating Consideration: The substitute parts operate at 650 MHz maximum frequency, compared to the original 800 MHz specification. Applications operating at or above 650 MHz require design verification to confirm adequate performance margin.

Temperature Range Differentiation: The 8533AG series (non-I variant) operates across 0°C to 70°C, while the 8533AGI series (I variant) extends to -40°C to 85°C, matching the original part's temperature range. For applications requiring full industrial temperature range operation, select 8533AGI-01LF or 8533AGI-01LFT.

Supply Voltage Range: Substitute parts specify 3.135V to 3.465V versus the original 3V to 3.6V. Verify that system power supply regulation falls within the narrower substitute specification.

Packaging Selection: Both Tube (LF) and Cut Tape & Digi-Reel® (LFT) packaging options are available for the 8533A series. Select based on assembly process requirements and inventory management practices.

Compliance Status: All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and REACH unaffected status, ensuring regulatory alignment with the original part.

Frequently Asked Questions (FAQ)

Q: Can the 8533A series parts directly replace the PI6C48533-01LEX in existing designs?

A: Physical and functional compatibility is maintained through identical package type (20-TSSOP), input:output ratio (2:4), differential support, and signal standards. However, the 650 MHz maximum frequency specification is lower than the original 800 MHz. Substitution is valid only if application clock frequencies do not exceed 650 MHz.

Q: What is the difference between 8533AG and 8533AGI variants?

A: The primary difference is operating temperature range. The 8533AG operates from 0°C to 70°C, while the 8533AGI extends to -40°C to 85°C, matching the original part's industrial temperature specification. Select 8533AGI for applications requiring full temperature range operation.

Q: Does packaging type (Tube vs. Cut Tape & Digi-Reel®) affect electrical performance?

A: No. The LF (Tube) and LFT (Cut Tape & Digi-Reel®) designations indicate packaging and delivery format only. Electrical specifications and performance are identical. Selection should be based on assembly process compatibility and supply chain requirements.

Q: Are the supply voltage ranges compatible?

A: The substitute parts specify 3.135V to 3.465V, which is narrower than the original 3V to 3.6V range. Verify that system power supply regulation operates within the substitute specification to ensure reliable operation.

Q: What inventory status should I consider for production planning?

A: The original PI6C48533-01LEX is Obsolete with 2245 units in stock. Substitute parts are Active status with higher inventory availability: 8533AG-01LFT has 11100 units, 8533AGI-01LFT has 4200 units, and other variants have 1310-1427 units. Active status ensures long-term availability for ongoing production.
