Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IR2308SPBF is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Half-Bridge topology
• Channel Architecture: Independent dual-channel design
• Gate Type Compatibility: IGBT and N-Channel MOSFET support
• Input Logic: Non-Inverting signal processing
• Electrical Specifications: Supply voltage range (10V ~ 20V), logic thresholds (VIL 0.8V, VIH 2.9V), peak output current (200mA source, 350mA sink), bootstrap voltage rating (600V maximum)
• Thermal Performance: Operating temperature range (-40°C ~ 150°C)
• Package Compatibility: 8-SOIC form factor with identical 0.154" (3.90mm) width
• Regulatory Compliance: ROHS3 compliance and MSL rating

Substitute parts must maintain identical electrical and mechanical specifications across all parameters listed above. Packaging format (bulk versus tape & reel) does not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The IR2308STRPBF is the direct functional equivalent of the IR2308SPBF. Both devices share identical electrical specifications, thermal ratings, and package geometry. The primary distinction is product status: IR2308SPBF is classified as Obsolete, while IR2308STRPBF maintains Active status with significantly higher inventory availability (29,900 units versus 650 units).

From a compliance perspective, both parts maintain ROHS3 certification and REACH Unaffected status, ensuring regulatory alignment for new designs and production continuity. The IR2308STRPBF is supplied in Tape & Reel packaging format, which is standard for high-volume manufacturing operations and automated assembly processes.

For applications currently utilizing the IR2308SPBF, transition to the IR2308STRPBF presents no functional risk, as all critical parameters—supply voltage, output current, timing characteristics, and thermal performance—remain unchanged. The substitute part is suitable for direct replacement in existing circuit designs without modification to PCB layout, component values, or firmware logic.
