Key Parameters

Substitute Part Grouping Explanation

Substitution of the PI5C32X245BE is determined by the following critical parameters:

• Circuit Configuration: 8 x 1:1 topology with 2 independent circuits
• Supply Voltage Compatibility: Single supply operation within overlapping voltage ranges
• Package Compatibility: 40-FSOP physical form factor (0.154", 3.90mm width)
• Operating Temperature Range: -40°C ~ 85°C
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The QS32X245Q2G from Renesas Electronics Corporation meets all substitution criteria. While the supplier device package designation differs (40-QVSOP vs. 40-BQSOP), both packages conform to the identical 40-FSOP physical specification, ensuring mechanical and electrical compatibility in PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

The QS32X245Q2G is a direct functional equivalent for the obsolete PI5C32X245BE. Both components share identical circuit topology, package dimensions, and regulatory compliance certifications. The supply voltage range of the QS32X245Q2G (4.75V ~ 5.25V) is a subset of the PI5C32X245BE specification (4.5V ~ 5.5V), ensuring compatibility in applications operating within the narrower range. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity classification, supporting equivalent handling and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the QS32X245Q2G replace the PI5C32X245BE in existing designs?

A: Yes. Both components feature identical 8 x 1:1 bus switch topology, 40-FSOP package dimensions, and operating temperature range. The supply voltage range of the QS32X245Q2G is compatible with applications designed for the PI5C32X245BE.

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

A: These are supplier-specific package naming conventions for the same 40-FSOP physical form factor (0.154", 3.90mm width). Both designations refer to identical mechanical and electrical specifications suitable for the same PCB footprint.

Q: Are there any voltage supply considerations when substituting?

A: The QS32X245Q2G operates within 4.75V ~ 5.25V, which overlaps with the PI5C32X245BE range of 4.5V ~ 5.5V. Designs operating at the extremes of the original specification (below 4.75V or above 5.25V) require evaluation against the substitute part's narrower range.

Q: Do both parts share the same regulatory compliance status?

A: Yes. Both the PI5C32X245BE and QS32X245Q2G are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS coding (8542.39.0001).
