PI3C32X245BE Equivalent & Substitute Parts

Part Overview

The PI3C32X245BE is an 8 x 1:1 bus switch IC manufactured by Diodes Incorporated, housed in a 40-BQSOP package. This component functions as a logic-level bus switch with two independent circuits, designed for signal routing and multiplexing applications in digital systems. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PI3C32X245BE is determined by the following critical parameters:

• Circuit Configuration: 8 x 1:1 bus switch topology with 2 independent circuits
• Package Compatibility: 40-pin FSOP form factor (0.154", 3.90mm width) for PCB layout compatibility
• Operating Temperature Range: -40°C ~ 85°C industrial temperature specification
• Mounting Type: Surface mount technology
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The QS32X245Q2G from Renesas Electronics Corporation meets these core functional and physical requirements. While the voltage supply range differs (4.75V ~ 5.25V versus 2.3V ~ 3.6V), this represents a distinct operating domain rather than a direct pin-compatible substitute. Selection between these parts depends on the system voltage architecture.

Parameter Comparison

Engineering Selection Recommendations

Both the PI3C32X245BE and QS32X245Q2G are classified as obsolete products. Selection between these components is contingent upon system voltage requirements:

• PI3C32X245BE: Suitable for low-voltage systems operating within the 2.3V ~ 3.6V range, including 3.3V logic domains.
• QS32X245Q2G: Suitable for standard 5V logic systems operating within the 4.75V ~ 5.25V range.

Both components maintain identical circuit topology (8 x 1:1 configuration with 2 independent circuits), identical package form factor (40-FSOP), and identical regulatory compliance status (ROHS3 compliant, REACH unaffected). The operating temperature range is identical across both parts (-40°C ~ 85°C), supporting industrial applications.

Frequently Asked Questions (FAQ)

Q: Can the QS32X245Q2G directly replace the PI3C32X245BE in an existing design?

A: Direct replacement is possible only if the system voltage architecture is compatible. The PI3C32X245BE operates at 2.3V ~ 3.6V, while the QS32X245Q2G operates at 4.75V ~ 5.25V. PCB layout compatibility is maintained due to identical 40-FSOP packaging.

Q: Are there pinout differences between these two parts?

A: Both parts share the same 8 x 1:1 bus switch configuration with 2 independent circuits in a 40-pin FSOP package. Pinout compatibility is maintained.

Q: What is the significance of the different package designations (40-BQSOP versus 40-QVSOP)?

A: Both designations refer to variants of the 40-pin FSOP form factor with identical physical dimensions (0.154", 3.90mm width). These are supplier-specific package naming conventions and do not affect PCB footprint compatibility.

Q: Are both parts suitable for industrial temperature applications?

A: Yes. Both the PI3C32X245BE and QS32X245Q2G support the -40°C ~ 85°C operating temperature range, meeting industrial specifications.

Q: What is the moisture sensitivity level for these components?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
