IR2118 High-Side Gate Driver IC - Equivalent & Substitute Parts

Part Overview

The IR2118 is a high-side gate driver IC designed for driving IGBT and N-Channel MOSFET devices in power management applications. This component operates as an inverting driver with a single channel configuration and supports bootstrap voltage up to 600V. The IR2118 is classified as obsolete, making identification of active equivalent parts essential for new designs and production continuity. The IR2118PBF represents the direct active substitute, maintaining identical electrical and mechanical specifications while offering current product availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IR2118 with the IR2118PBF is based on complete electrical and mechanical parameter equivalence. Both parts share identical specifications across all critical functional parameters: supply voltage range (10V ~ 20V), logic voltage thresholds (6V, 9.5V), peak output current ratings (250mA source, 500mA sink), bootstrap voltage capability (600V), timing characteristics (80ns rise, 40ns fall), and operating temperature range (-40°C ~ 150°C). Both components utilize the same 8-DIP through-hole package format (0.300", 7.62mm). The substitution is valid based on matching driven configuration (high-side), channel type (single), gate type (IGBT, N-Channel MOSFET), and input type (inverting). The primary distinction is product status and compliance certification, not functional capability.

Parameter Comparison

Engineering Selection Recommendations

The IR2118PBF is the direct functional equivalent of the IR2118 and serves as the primary substitute for obsolete IR2118 applications. Selection of IR2118PBF is supported by complete electrical parameter equivalence and active product status. The IR2118PBF provides ROHS3 compliance, whereas the original IR2118 is non-compliant, making IR2118PBF the appropriate choice for applications subject to RoHS regulations. Both parts are REACH Unaffected and classified under ECCN EAR99. The through-hole 8-DIP package format remains consistent, enabling direct board-level substitution without layout modification. Tube packaging for IR2118PBF supports standard component handling and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can IR2118PBF directly replace IR2118 in existing designs? A: Yes. The IR2118PBF maintains identical electrical specifications and package format. Direct substitution is valid for all electrical and mechanical parameters.

Q: What is the primary difference between IR2118 and IR2118PBF? A: Product status and compliance certification. IR2118 is obsolete and RoHS non-compliant. IR2118PBF is active and ROHS3 compliant. Electrical and mechanical specifications are identical.
