PI5C32X245B Equivalent & Substitute Parts

Part Overview

The PI5C32X245B is an 8 x 1:1 bus switch logic IC manufactured by Diodes Incorporated in a 40-BQSOP surface mount package. This component functions as a multiplexer for digital signal routing in single supply applications. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PI5C32X245B is determined by the following critical parameters:

• Circuit Configuration: Must be 8 x 1:1 bus switch topology
• Independent Circuits: Must provide 2 independent circuits
• Voltage Supply Source: Must operate on single supply architecture
• Supply Voltage Range: Must accommodate 4.5V to 5.5V operation
• Operating Temperature: Must support -40°C to 85°C range
• Package / Case: Must be 40-FSOP (0.154", 3.90mm Width) for PCB compatibility
• Mounting Type: Must be surface mount

The QS32X245Q2G from Renesas Electronics Corporation meets all functional and mechanical requirements for direct substitution, with the exception of a narrower supply voltage specification (4.75V ~ 5.25V), which represents a subset of the original part's range.

Parameter Comparison

Engineering Selection Recommendations

The QS32X245Q2G qualifies as a direct functional substitute for the PI5C32X245B based on matching circuit topology, pin count, package dimensions, and operating temperature specifications. Both parts are classified as obsolete products.

A key distinction exists in regulatory compliance: the QS32X245Q2G carries ROHS3 compliance certification, while the PI5C32X245B is RoHS non-compliant. For applications subject to RoHS requirements, the Renesas part provides compliance advantage.

The supply voltage range of the QS32X245Q2G (4.75V ~ 5.25V) is narrower than the PI5C32X245B (4.5V ~ 5.5V). Applications operating at the extremes of the original specification (below 4.75V or above 5.25V) require verification against actual circuit supply tolerances before substitution.

Both parts maintain identical REACH and ECCN classifications (REACH Unaffected, EAR99), supporting equivalent export and regulatory treatment.

Frequently Asked Questions (FAQ)

Q: Can the QS32X245Q2G replace the PI5C32X245B in existing designs?

A: Yes, the QS32X245Q2G is functionally equivalent for applications operating within the 4.75V to 5.25V supply range. The identical 8 x 1:1 circuit configuration, 40-FSOP package dimensions, and operating temperature range support direct substitution at the PCB level.

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

A: Both designations refer to the same 40-pin FSOP package with 0.154" width and 3.90mm body dimension. The different supplier package codes reflect manufacturer-specific naming conventions but do not indicate physical or electrical differences relevant to PCB assembly or functionality.

Q: Does the narrower supply voltage range of the QS32X245Q2G affect compatibility?

A: The QS32X245Q2G operates within 4.75V to 5.25V, which is a subset of the PI5C32X245B range (4.5V to 5.5V). If your circuit supply voltage remains within 4.75V to 5.25V, no compatibility issues exist. Applications requiring operation below 4.75V or above 5.25V must confirm the substitute part's suitability through circuit analysis.

Q: Are there differences in moisture sensitivity or handling requirements?

A: Both parts carry MSL 1 (Unlimited) classification, indicating identical moisture sensitivity levels and storage requirements. No additional handling precautions are necessary when transitioning between these parts.

Q: What is the impact of RoHS compliance differences?

A: The QS32X245Q2G is ROHS3 compliant while the PI5C32X245B is non-compliant. For applications or markets requiring RoHS certification, the Renesas part provides regulatory alignment. For legacy systems without RoHS requirements, both parts are functionally equivalent.
