PI3C32X245BEX Equivalent & Substitute Parts

Part Overview

The PI3C32X245BEX 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 single supply operation across a voltage range of 2.3V to 3.6V. The device is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PI3C32X245BEX 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
• Operating Temperature Range: -40°C ~ 85°C operational envelope
• Mounting Type: Surface mount technology
• Compliance Standards: ROHS3 compliance and MSL Level 1 rating

The QS32X245Q2G from Renesas Electronics Corporation satisfies these core substitution criteria. While the voltage supply range differs (4.75V ~ 5.25V versus 2.3V ~ 3.6V), this represents a distinct operational class rather than a direct pin-compatible replacement. Selection between these parts depends on the specific supply voltage requirements of the target application.

Parameter Comparison

Engineering Selection Recommendations

Both the PI3C32X245BEX and QS32X245Q2G share identical circuit topology, package form factor, and thermal operating range. Both components maintain ROHS3 compliance and MSL Level 1 ratings, ensuring equivalent environmental and regulatory standing.

The primary selection criterion is supply voltage compatibility. The PI3C32X245BEX operates within 2.3V to 3.6V, suitable for low-voltage applications including 3.3V logic systems. The QS32X245Q2G operates within 4.75V to 5.25V, suitable for 5V logic systems. Selection must align with the target system's supply voltage specification.

Both parts are classified as obsolete. Inventory availability should be verified through authorized distributors prior to design commitment.

Frequently Asked Questions (FAQ)

Q: Can the QS32X245Q2G directly replace the PI3C32X245BEX in an existing design?

A: Direct replacement is possible only if the target system operates at 4.75V to 5.25V supply voltage. If the original design uses 2.3V to 3.6V supply, the QS32X245Q2G will not function within specification. Pin configuration and package footprint are identical, but voltage supply requirements must match.

Q: What is the significance of the 40-FSOP package specification?

A: The 40-FSOP (0.154", 3.90mm width) package defines the physical footprint and pin spacing. Both substitute parts share this identical package specification, ensuring PCB layout compatibility without redesign.

Q: Are there any compliance differences between these parts?

A: Both parts maintain identical ROHS3 compliance, REACH unaffected status, and MSL Level 1 moisture sensitivity ratings. No compliance differentiation exists between the two components.

Q: Why are both parts classified as obsolete?

A: Obsolete status indicates these components are no longer in active production. Availability is limited to existing inventory through authorized distributors. For new designs, evaluation of current-generation bus switch alternatives is recommended.

Q: How do the independent circuits affect substitution?

A: Both parts feature 2 independent circuits within the 8 x 1:1 configuration. This functional equivalence ensures that applications utilizing the circuit partitioning of the PI3C32X245BEX will maintain identical behavior with the QS32X245Q2G, provided voltage supply requirements are met.
