Key Parameters

Substitute Part Grouping Explanation

Substitution of the ISL6161IBZA-T is determined by strict equivalence across the following critical parameters:

• Functional Type: Hot Swap Controller with 2-channel configuration
• Application Domain: PCI Express® systems
• Control Features: Latched Fault protection with programmable Current Limit and Fault Timeout
• Electrical Specifications: Supply voltage range 10.5V ~ 13.2V, supply current 8 mA
• Package Compatibility: 14-SOIC surface mount package with identical physical dimensions
• Compliance Standards: ROHS3 compliance and MSL 3 rating

The ISL6161CBZA-T meets all these criteria and is classified as the direct substitute. Both parts share the same base product number (ISL6161) and are manufactured by Renesas Electronics Corporation, ensuring functional and electrical interchangeability within PCI Express hot swap applications.

Parameter Comparison

Engineering Selection Recommendations

The ISL6161CBZA-T is the qualified substitute for the obsolete ISL6161IBZA-T. Both components maintain identical electrical and functional specifications across all critical parameters including supply voltage, channel configuration, programmable features, and package geometry.

The primary distinction is product status: the ISL6161IBZA-T is obsolete with limited inventory availability, while the ISL6161CBZA-T is active with established supply chains. The ISL6161CBZA-T operates within a narrower temperature range (0°C ~ 70°C versus -40°C ~ 85°C), which must be evaluated against application requirements. Both parts carry ROHS3 compliance and identical MSL ratings, ensuring regulatory and environmental compatibility.

For new designs or legacy system updates, the ISL6161CBZA-T is the appropriate selection. For applications requiring the extended temperature range of the original part, this temperature differential must be assessed against operational environment specifications.

Frequently Asked Questions (FAQ)

Q: Can the ISL6161CBZA-T directly replace the ISL6161IBZA-T in existing designs?

A: Yes, the ISL6161CBZA-T is functionally and electrically equivalent. Both parts share identical channel count, supply voltage specifications, programmable features, and 14-SOIC package dimensions. Substitution is valid provided the application operating temperature remains within 0°C ~ 70°C.

Q: What is the key difference between these two parts?

A: The ISL6161IBZA-T is obsolete with extended temperature range (-40°C ~ 85°C), while the ISL6161CBZA-T is active with standard industrial temperature range (0°C ~ 70°C). Packaging format differs: bulk versus Tape & Reel.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant with identical MSL 3 ratings and REACH unaffected status. Regulatory compliance is equivalent.

Q: Does package format affect electrical performance?

A: No. Both parts use the 14-SOIC package with identical physical dimensions and electrical characteristics. Packaging format (bulk versus Tape & Reel) affects procurement and handling only, not functional performance.

Q: What should be verified before substitution?

A: Confirm that the application operating temperature range does not exceed 0°C ~ 70°C. Verify that PCI Express hot swap control requirements match the 2-channel latched fault configuration with programmable current limit and fault timeout.
