Key Parameters

Substitute Part Grouping Explanation

Substitution of the IR2127 is determined by strict equivalence across the following critical parameters:

• Driven configuration (high-side or low-side capability)
• Channel type and number of drivers (single channel)
• Gate type compatibility (IGBT and N-Channel MOSFET)
• Supply voltage range (12V ~ 20V)
• Logic voltage thresholds (VIL 0.8V, VIH 3V)
• Peak output current specifications (250mA source, 500mA sink)
• Input logic type (non-inverting)
• Bootstrap voltage rating (600V maximum)
• Rise and fall time characteristics (80ns rise, 40ns fall)
• Package and mounting configuration (8-DIP through-hole)
• Operating temperature range (-40°C ~ 150°C)

Only parts meeting all these electrical and mechanical parameters qualify as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The IR2127PBF is a direct functional and electrical equivalent to the IR2127. Both parts share identical electrical specifications, package configuration, and performance characteristics across all critical parameters.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The IR2127 is classified as obsolete, while the IR2127PBF maintains active product status with current manufacturing availability. The IR2127PBF additionally meets ROHS3 compliance requirements, whereas the IR2127 is RoHS non-compliant.

For new designs or production continuity requiring gate driver functionality equivalent to the IR2127, the IR2127PBF is the appropriate selection. Both parts are supplied by Infineon Technologies and maintain identical electrical performance within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can IR2127PBF be used as a direct replacement for IR2127 in existing designs?

A: Yes. The IR2127PBF is electrically and mechanically identical to the IR2127 across all specified parameters. Pin configuration, package dimensions, and electrical performance are equivalent. Direct substitution is supported without circuit modification.

Q: What is the difference between IR2127 and IR2127PBF?

A: The IR2127PBF is the active production variant of the IR2127. Differences include product status (active versus obsolete), RoHS compliance (ROHS3 compliant versus non-compliant), and packaging format (tube versus unspecified). Electrical specifications and performance characteristics are identical.

Q: Why is the IR2127 listed as obsolete?

A: The IR2127 has reached end-of-life status in Infineon's product portfolio. The IR2127PBF represents the current active equivalent for this gate driver topology and is recommended for all new applications and ongoing production requirements.

Q: Are there any thermal or reliability differences between these parts?

A: No. Both parts operate across the identical temperature range (-40°C to 150°C junction temperature) and share identical electrical performance specifications. Thermal and reliability characteristics are equivalent.

Q: What packaging options are available?

A: The IR2127 packaging format is not specified in available documentation. The IR2127PBF is supplied in tube packaging. Both maintain the 8-DIP (0.300", 7.62mm) through-hole package configuration.

Q: Are these parts suitable for high-side and low-side gate driving applications?

A: Yes. Both the IR2127 and IR2127PBF support high-side or low-side driven configuration with 600V maximum bootstrap voltage rating, making them suitable for both topologies within the specified supply voltage range of 12V to 20V.
