Key Parameters

Substitute Part Grouping Explanation

Substitution of the IXDI509PI is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Low-Side (must match exactly)
• Channel Type: Single (must match exactly)
• Gate Type: IGBT, N-Channel, P-Channel MOSFET (must match exactly)
• Input Type: Inverting (must match exactly)
• Package / Case: 8-DIP (0.300", 7.62mm) (must match exactly)
• Mounting Type: Through Hole (must match exactly)

Substitute components must maintain compatibility within the specified supply voltage range and output current ratings. Rise and fall time characteristics may vary within acceptable operational margins for gate driver applications.

Parameter Comparison

Engineering Selection Recommendations

The IXDI609PI is a direct functional substitute for the IXDI509PI based on electrical and mechanical parameter equivalence. Key selection factors include:

• The IXDI609PI maintains all critical gate driver specifications: low-side configuration, single-channel inverting input, identical output current ratings, and matching 8-DIP through-hole package.
• The IXDI609PI operates across an extended supply voltage range (4.5V ~ 35V versus 4.5V ~ 30V), providing additional design margin in applications operating near the upper voltage limit.
• The IXDI609PI exhibits improved switching performance with faster rise and fall times (22ns/15ns versus 25ns/23ns), which may reduce switching losses in high-frequency applications.
• The IXDI609PI is actively manufactured and widely available, addressing supply chain continuity concerns associated with the obsolete IXDI509PI.
• The IXDI609PI meets ROHS3 compliance, aligning with current environmental and regulatory requirements.

Both components share identical moisture sensitivity levels and REACH compliance status, ensuring equivalent handling and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the IXDI609PI be used as a direct replacement for the IXDI509PI in existing designs?

A: Yes. The IXDI609PI is electrically and mechanically compatible with the IXDI509PI. Both components feature identical low-side gate driver configurations, single-channel inverting inputs, 9A peak output current ratings, and 8-DIP through-hole packaging. No PCB modifications are required for substitution.

Q: What are the key differences between the IXDI509PI and IXDI609PI?

A: The primary differences are: (1) supply voltage range—IXDI609PI supports 4.5V ~ 35V versus IXDI509PI's 4.5V ~ 30V; (2) switching speed—IXDI609PI has faster rise/fall times (22ns/15ns versus 25ns/23ns); (3) product status—IXDI609PI is active production while IXDI509PI is obsolete; (4) compliance—IXDI609PI is ROHS3 compliant.

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

A: Both components operate across the same temperature range (-55°C ~ 150°C junction temperature) and share identical moisture sensitivity levels (MSL 1, Unlimited). The faster switching characteristics of the IXDI609PI may result in reduced switching losses in high-frequency applications, potentially improving thermal performance.

Q: Is the IXDI609PI available in the same packaging as the IXDI509PI?

A: Yes. Both components use 8-DIP (0.300", 7.62mm) through-hole packages with identical pin configurations and mechanical dimensions. Direct socket substitution is possible without PCB redesign.

Q: What is the supply voltage compatibility between these two parts?

A: The IXDI509PI operates from 4.5V to 30V, while the IXDI609PI operates from 4.5V to 35V. The IXDI609PI is compatible with all applications designed for the IXDI509PI. Applications requiring operation above 30V require the IXDI609PI.

Q: Are there any logic voltage level differences that affect circuit design?

A: Logic voltage thresholds differ slightly: IXDI509PI specifies VIL/VIH of 0.8V/2.4V, while IXDI609PI specifies 0.8V/3V. Both are compatible with standard TTL and CMOS logic levels. The higher VIH threshold of the IXDI609PI provides additional noise margin in noisy environments.
