ISL6141IB Hot Swap Controller Equivalent & Substitute Parts

Part Overview

The ISL6141IB is a hot swap controller IC designed for -48V VoIP applications, manufactured by Renesas Electronics Corporation. This single-channel device provides protection and control functions for power supply systems requiring automatic retry and fault timeout capabilities. The ISL6141IB is classified as obsolete, making identification of active equivalent parts essential for ongoing system support and new design implementations. Substitute parts must maintain identical electrical specifications and package compatibility to ensure direct replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ISL6141IB are qualified based on strict equivalence of the following parameters:

• Single-channel hot swap controller architecture
• 8-SOIC surface mount package (0.154", 3.90mm Width)
• Supply voltage range: 20V ~ 80V
• Supply current: 2.4 mA
• Operating temperature range: -40°C ~ 85°C
• Programmable features: Current Limit, OVP, UVLO
• Auto Retry and Fault Timeout functionality
• -48V VoIP application compatibility

The ISL6141IBZA qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters specified above.

Parameter Comparison

Engineering Selection Recommendations

The ISL6141IBZA is the qualified substitute for the obsolete ISL6141IB. Both parts share identical electrical specifications, package geometry, and functional capabilities. The primary distinction is product status: the ISL6141IB is obsolete while the ISL6141IBZA maintains active production status through Intersil.

For new designs and ongoing system support, the ISL6141IBZA is the appropriate selection. The active product status ensures continued availability and manufacturing support. Both parts are classified as RoHS non-compliant and REACH Unaffected, with identical export classification (EAR99).

Frequently Asked Questions (FAQ)

Q: Can the ISL6141IBZA directly replace the ISL6141IB in existing designs?

A: Yes. The ISL6141IBZA provides complete electrical and mechanical equivalence. Pin configuration, package dimensions, supply voltage range, operating temperature range, and all programmable features are identical. No circuit modifications are required.

Q: What is the primary reason to transition from ISL6141IB to ISL6141IBZA?

A: The ISL6141IB is classified as obsolete. The ISL6141IBZA maintains active production status, ensuring long-term component availability and manufacturing support for -48V VoIP hot swap applications.

Q: Are there any compliance differences between these parts?

A: Both parts share identical RoHS and REACH compliance status. Both are RoHS non-compliant and REACH Unaffected. Export classification (EAR99) and HTSUS codes differ slightly due to manufacturer classification differences but do not affect functional equivalence.

Q: What package format is used for both parts?

A: Both the ISL6141IB and ISL6141IBZA use the 8-SOIC package with 0.154" width (3.90mm). This surface mount package is identical for both parts, enabling direct PCB compatibility.

Q: Are the programmable features identical between these parts?

A: Yes. Both parts support identical programmable features: Current Limit, OVP (Overvoltage Protection), and UVLO (Undervoltage Lockout). Firmware and configuration settings require no modification.
