ISL6117CB Hot Swap Controller Equivalent & Substitute Parts

Part Overview

The ISL6117CB is a hot swap controller manufactured by Renesas Electronics Corporation, designed for general-purpose applications requiring single-channel hot swap control with latched fault protection. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The ISL6117CB operates within a 9V to 15V supply voltage range and provides programmable current limiting and fault timeout features in an 8-SOIC surface mount package.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ISL6117CB is determined by the following critical parameters:

• Package Compatibility: Both parts must use 8-SOIC (0.154", 3.90mm Width) surface mount packaging to ensure PCB layout compatibility without redesign.
• Functional Type: Both must be single-channel hot swap controllers with latched fault capability.
• Core Programmable Features: Current limit and fault timeout functionality must be present in the substitute.
• Mounting Type: Surface mount requirement must be maintained.

The MAX5932ESA+ meets all substitution criteria. While it offers extended supply voltage range (9V ~ 80V), lower supply current (1.4 mA), and additional programmable features (OVP, Slew Rate, UVLO), these represent functional enhancements rather than incompatibilities. The identical package footprint and core hot swap controller architecture enable direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The MAX5932ESA+ is the qualified substitute for the ISL6117CB based on the following engineering criteria:

Product Status: The ISL6117CB is obsolete, while the MAX5932ESA+ is active. Active product status ensures ongoing availability, manufacturing support, and compliance with current industry standards.

Regulatory Compliance: The MAX5932ESA+ is ROHS3 compliant, whereas the ISL6117CB is RoHS non-compliant. For applications subject to RoHS regulations, the MAX5932ESA+ satisfies compliance requirements.

Package Compatibility: Both components use identical 8-SOIC packaging, eliminating the need for PCB redesign or layout modifications.

Functional Equivalence: Both devices provide single-channel hot swap control with latched fault protection and programmable current limit and fault timeout features. The MAX5932ESA+ includes additional programmable capabilities (OVP, Slew Rate, UVLO) that do not conflict with existing ISL6117CB designs.

Supply Voltage Consideration: The MAX5932ESA+ supports 9V ~ 80V, which encompasses the ISL6117CB operating range of 9V ~ 15V. Designs operating within the original 9V ~ 15V specification remain fully compatible.

Frequently Asked Questions (FAQ)

Q: Can the MAX5932ESA+ directly replace the ISL6117CB without PCB modifications?

A: Yes. Both components use the 8-SOIC (0.154", 3.90mm Width) package with identical pin assignments for hot swap controller applications. No PCB layout changes are required.

Q: What is the impact of the MAX5932ESA+ supporting 9V ~ 80V versus the ISL6117CB's 9V ~ 15V?

A: The extended voltage range of the MAX5932ESA+ is a superset of the ISL6117CB specification. Designs operating within 9V ~ 15V experience no functional changes. The substitute is fully backward compatible for the original operating range.

Q: Does the MAX5932ESA+ provide the same programmable features as the ISL6117CB?

A: The MAX5932ESA+ includes all ISL6117CB programmable features (current limit, fault timeout) plus additional capabilities (OVP, slew rate, UVLO). Existing firmware and control logic remain compatible; additional features are optional.

Q: Why is RoHS compliance relevant for this substitution?

A: The ISL6117CB is RoHS non-compliant, while the MAX5932ESA+ is ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, the MAX5932ESA+ satisfies compliance mandates.

Q: Is the MAX5932ESA+ suitable for designs requiring -40°C operation?

A: Yes. The MAX5932ESA+ operates from -40°C ~ 85°C, extending the lower temperature limit compared to the ISL6117CB (0°C ~ 85°C). This makes it suitable for extended temperature range applications.

Q: What is the significance of the MAX5932ESA+ being an active product?

A: Active product status ensures continued manufacturing, availability, technical support, and compliance with evolving industry standards. The obsolete ISL6117CB may face supply constraints and lack of vendor support.
