Key Parameters

Substitute Part Grouping Explanation

Substitution of the IR2106STR is determined by strict equivalence across the following critical parameters:

• Driven configuration (half-bridge topology)
• Independent dual-channel architecture
• Gate type compatibility (IGBT and N-Channel MOSFET support)
• Supply voltage range (10V ~ 20V)
• Logic voltage thresholds (VIL 0.8V, VIH 2.9V)
• Peak output current specifications (200mA source, 350mA sink)
• Non-inverting input logic
• Bootstrap voltage rating (600V maximum)
• Timing characteristics (150ns rise, 50ns fall)
• Operating temperature range (-40°C ~ 150°C)
• Package form factor (8-SOIC)
• Surface mount mounting type

The IR2106STRPBF is identified as a direct substitute based on complete parameter alignment across all electrical and mechanical specifications.

Engineering Selection Recommendations

The IR2106STRPBF is the direct substitute for the IR2106STR based on complete electrical and mechanical parameter equivalence. Selection between these parts should be determined by the following factors:

Product Status: The IR2106STR is obsolete, while the IR2106STRPBF maintains active product status. For new designs or ongoing production requiring long-term component availability, the IR2106STRPBF is the appropriate selection.

Regulatory Compliance: The IR2106STRPBF is ROHS3 compliant, whereas the IR2106STR is RoHS non-compliant. Applications subject to RoHS regulations require the IR2106STRPBF.

Moisture Sensitivity: The IR2106STR carries MSL 1 (unlimited shelf life), while the IR2106STRPBF carries MSL 2 (1-year shelf life). Storage and handling protocols must reflect the respective moisture sensitivity classifications.

Packaging Format: The IR2106STRPBF is available in Cut Tape (CT) and Digi-Reel packaging options, providing flexibility for both prototype and production volume requirements.

Frequently Asked Questions (FAQ)

Q: Can the IR2106STRPBF directly replace the IR2106STR in existing designs?

A: Yes. The IR2106STRPBF provides complete electrical and mechanical equivalence to the IR2106STR. All functional parameters, including supply voltage, output current, timing characteristics, and package form factor, are identical. Direct substitution is supported without circuit modification.

Q: What is the primary reason to transition from IR2106STR to IR2106STRPBF?

A: The IR2106STR is obsolete product status. The IR2106STRPBF is the active equivalent part, ensuring continued supply chain availability and long-term component sourcing for production applications.

Q: Are there compliance differences between these parts?

A: Yes. The IR2106STRPBF is ROHS3 compliant, while the IR2106STR is RoHS non-compliant. Applications requiring RoHS compliance must use the IR2106STRPBF. Additionally, moisture sensitivity levels differ: IR2106STR is MSL 1, and IR2106STRPBF is MSL 2.

Q: Is the 8-SOIC package identical for both parts?

A: Yes. Both parts use the 8-SOIC package with 0.154" (3.90mm) width. PCB footprints and land patterns are identical, supporting direct board-level substitution.

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

A: Substitution is based on half-bridge configuration, independent dual-channel architecture, 10V to 20V supply voltage range, 200mA/350mA peak output current, 600V bootstrap voltage rating, non-inverting logic, and -40°C to 150°C operating temperature range. The IR2106STRPBF meets all these specifications.
