PI5C32X245BEX Equivalent & Substitute Parts

Part Overview

The PI5C32X245BEX is an 8 x 1:1 bus switch IC manufactured by Diodes Incorporated in a 40-BQSOP surface mount package. This component functions as a logic-level bus switch for signal routing and multiplexing applications. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PI5C32X245BEX is determined by the following critical parameters:

• Circuit Configuration: 8 x 1:1 topology with 2 independent circuits
• Package Compatibility: 40-FSOP form factor (0.154", 3.90mm width) for PCB layout compatibility
• Voltage Supply Range: Single supply operation within specified voltage window
• Operating Temperature: -40°C to 85°C industrial temperature range
• Compliance: ROHS3 compliance and MSL Level 1 rating

The QS32X245Q2G from Renesas Electronics Corporation meets all substitution criteria within these parameters. While the supplier device package designation differs (40-QVSOP vs. 40-BQSOP), both packages conform to the same 40-FSOP mechanical specification, ensuring footprint compatibility.

Parameter Comparison

Engineering Selection Recommendations

The QS32X245Q2G is a direct functional substitute for the PI5C32X245BEX. Both components share identical circuit topology, package footprint, and compliance certifications. The voltage supply range of the Renesas part (4.75V ~ 5.25V) is a subset of the Diodes part (4.5V ~ 5.5V), making it suitable for applications operating within the narrower window. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, supporting equivalent reliability profiles in production environments.

Frequently Asked Questions (FAQ)

Q: Can the QS32X245Q2G replace the PI5C32X245BEX in existing designs?

A: Yes. Both parts share the same 40-FSOP package footprint, circuit configuration (8 x 1:1), and operating temperature range. PCB layout and pinout compatibility are maintained.

Q: What is the difference between 40-BQSOP and 40-QVSOP package designations?

A: Both designations refer to variants of the 40-FSOP package family with identical mechanical dimensions (0.154", 3.90mm width). The different supplier package codes reflect manufacturer-specific naming conventions without affecting physical compatibility.

Q: Are there voltage supply differences between these parts?

A: The PI5C32X245BEX operates at 4.5V ~ 5.5V, while the QS32X245Q2G operates at 4.75V ~ 5.25V. The Renesas part requires operation within a narrower voltage window. Designs operating at the extremes of the Diodes specification (below 4.75V or above 5.25V) must be evaluated for compatibility with the Renesas substitute.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the PI5C32X245BEX and QS32X245Q2G are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Moisture sensitivity level is 1 (unlimited) for both parts.

Q: Why is the PI5C32X245BEX marked as obsolete?

A: Obsolete status indicates the part is no longer in active production by the manufacturer. The QS32X245Q2G provides functional continuity for applications requiring 8 x 1:1 bus switch functionality in the 40-FSOP package.
