Key Parameters

Substitute Part Grouping Explanation

Substitution of the IR2102 is determined by strict equivalence across electrical performance and mechanical form factor. The critical parameters governing substitution are:

• Driven configuration (half-bridge topology)
• Number of independent driver channels (2)
• Gate type compatibility (IGBT and N-Channel MOSFET support)
• Supply voltage range (10V ~ 20V)
• Logic input voltage thresholds (VIL 0.8V, VIH 3V)
• Peak output current specifications (source 210mA, sink 360mA)
• Bootstrap voltage rating (600V maximum)
• Timing characteristics (rise/fall times 100ns/50ns)
• Operating temperature range (-40°C ~ 150°C)
• Package form factor (8-DIP through-hole)

The IR2102PBF maintains identical specifications across all these parameters and represents a direct functional and pin-compatible substitute.

Parameter Comparison

Engineering Selection Recommendations

The IR2102PBF is the appropriate substitute for the obsolete IR2102. Both parts are classified under the same ECCN (EAR99) and HTSUS code (8542.39.0001), indicating regulatory equivalence. The IR2102PBF maintains active product status with International Rectifier, ensuring ongoing availability and supply chain continuity. All electrical parameters, timing characteristics, and mechanical specifications are identical, supporting direct replacement in existing designs without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can IR2102PBF be used as a direct replacement for IR2102? A: Yes. The IR2102PBF is electrically and mechanically identical to the IR2102 across all specified parameters, including supply voltage, output current, timing, and package form factor. Direct substitution is supported without design changes.

Q: Are there any differences in the 8-DIP package between these parts? A: No. Both parts use the same 8-DIP (0.300", 7.62mm) through-hole package with identical pin configuration and mechanical dimensions.

Q: What is the significance of the IR2102 being obsolete? A: The obsolete status of the IR2102 indicates it is no longer manufactured by Infineon Technologies. The IR2102PBF from International Rectifier provides an active, continuously available equivalent for new designs and production continuity.

Q: Are the logic input voltage thresholds identical? A: Yes. Both parts specify VIL of 0.8V and VIH of 3V, ensuring compatible signal conditioning and control logic integration.

Q: Do both parts support the same gate driver applications? A: Yes. Both parts support IGBT and N-Channel MOSFET gate driving in half-bridge configurations with identical electrical performance across the specified operating temperature range of -40°C to 150°C.
