IR2102STR Gate Driver IC - Equivalent & Substitute Parts

Part Overview

The IR2102STR is a half-bridge gate driver IC manufactured by Infineon Technologies, designed to drive IGBT and N-Channel MOSFET devices in power management applications. This device features independent dual-channel configuration with inverting input logic, operating across a 10V to 20V supply range with peak output currents of 210mA (source) and 360mA (sink).

The IR2102STR is classified as obsolete. Due to its discontinued status, identifying functionally equivalent substitute parts becomes necessary for ongoing system maintenance, redesign efforts, and procurement continuity. Substitute parts must maintain compatibility across electrical specifications, package format, and functional performance characteristics.

Substitute Part Grouping Explanation

Substitute parts for the IR2102STR are identified based on strict electrical and mechanical parameter alignment. The primary substitution criterion is the base product number IR2102, which defines the functional family and electrical characteristics.

The IR2102STRPBF qualifies as a direct substitute based on the following key parameters:

• Base Product Number: IR2102 (identical functional specification)
• Package Format: 8-SOIC surface mount configuration
• Driven Configuration: Half-bridge topology
• Number of Drivers: 2 independent channels
• Gate Type: IGBT and N-Channel MOSFET compatibility
• Supply Voltage Range: 10V ~ 20V
• Input Logic: Inverting configuration
• Bootstrap Voltage Rating: 600V maximum

The IR2102STRPBF maintains electrical equivalence across all critical performance parameters including output current ratings, logic voltage thresholds, and thermal operating range.

Parameter Comparison

Engineering Selection Recommendations

The IR2102STRPBF is the direct functional equivalent for the obsolete IR2102STR. Both parts share identical electrical specifications across all critical parameters including supply voltage, output current ratings, logic thresholds, and thermal operating range.

The primary distinction between these parts is product status: the IR2102STR is obsolete, while the IR2102STRPBF maintains active production status. This status difference ensures long-term availability and supply chain continuity for the IR2102STRPBF.

Both parts maintain REACH Unaffected compliance status. The IR2102STR is RoHS non-compliant, while the IR2102STRPBF's RoHS status is not specified in the provided data. Compliance requirements should be verified against specific application and regional regulations.

Frequently Asked Questions (FAQ)

Q: Can IR2102STRPBF directly replace IR2102STR in existing designs?

A: Yes. The IR2102STRPBF is electrically and mechanically equivalent to the IR2102STR. Both devices feature identical half-bridge gate driver configuration, dual independent channels, 8-SOIC package format, and all critical electrical parameters including supply voltage range (10V ~ 20V), output current ratings (210mA source, 360mA sink), and operating temperature range (-40°C ~ 150°C).

Q: What is the primary reason to substitute IR2102STR with IR2102STRPBF?

A: The IR2102STR is classified as obsolete. The IR2102STRPBF maintains active production status, ensuring availability for new procurement, system maintenance, and redesign efforts.

Q: Are there package compatibility concerns between these parts?

A: No. Both parts use the 8-SOIC surface mount package format with identical 0.154" (3.90mm) width specification. PCB footprints and assembly processes remain unchanged.

Q: Do these parts have different compliance certifications?

A: Both parts maintain REACH Unaffected status. The IR2102STR is RoHS non-compliant. The IR2102STRPBF's RoHS compliance status is not specified in available data and should be verified with the manufacturer for applications requiring RoHS compliance.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution compatibility is determined by: base product number (IR2102), half-bridge driven configuration, dual independent channels, IGBT and N-Channel MOSFET gate type support, 10V ~ 20V supply voltage range, 0.8V/3V logic thresholds, 210mA/360mA peak output currents, inverting input logic, and 600V bootstrap voltage rating.
