Key Parameters

Substitute Part Grouping Explanation

Substitution of the IXDI509SIA is determined by the following critical parameters that must remain compatible:

• Driven Configuration: Low-Side (must match)
• Channel Type: Single (must match)
• Number of Drivers: 1 (must match)
• Gate Type: IGBT, N-Channel, P-Channel MOSFET (must match)
• Input Type: Inverting (must match)
• Package / Case: 8-SOIC (must match)
• Mounting Type: Surface Mount (must match)

The IXDI609SIA qualifies as a direct substitute based on these core functional and mechanical parameters. Both devices share identical driven configuration, channel type, driver count, gate type support, input type, and package specifications. The substitute part maintains full compatibility with existing PCB layouts and circuit designs.

Parameter Comparison

Engineering Selection Recommendations

The IXDI609SIA is the direct substitute for the obsolete IXDI509SIA. Both devices maintain identical functional specifications for driven configuration, channel type, driver count, gate type support, input type, and package form factor.

The IXDI609SIA offers the following advantages:

• Active product status ensures ongoing availability and manufacturing support
• Extended supply voltage range (4.5V ~ 35V versus 4.5V ~ 30V) provides broader application flexibility
• Improved rise and fall time performance (22ns/15ns versus 25ns/23ns) delivers faster switching characteristics
• ROHS3 compliance meets current environmental and regulatory requirements
• Identical MSL rating and thermal operating range maintain design compatibility

Selection of the IXDI609SIA eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can the IXDI609SIA be used as a direct replacement for the IXDI509SIA in existing designs?

A: Yes. Both devices share identical driven configuration (low-side), channel type (single), driver count (1), gate type support (IGBT, N-Channel, P-Channel MOSFET), input type (inverting), and package specifications (8-SOIC surface mount). No PCB modifications are required.

Q: What are the key differences between these two parts?

A: The IXDI609SIA features an extended supply voltage range (35V maximum versus 30V), improved switching speed (22ns/15ns rise/fall time versus 25ns/23ns), higher logic input threshold (3V VIH versus 2.4V), and active product status with ROHS3 compliance. The IXDI509SIA is obsolete.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 8-SOIC package with 0.154" (3.90mm) width. Pin-to-pin compatibility is maintained.

Q: Does the improved switching speed of the IXDI609SIA affect circuit design?

A: The faster rise and fall times of the IXDI609SIA represent an improvement over the IXDI509SIA. Existing circuit designs will function correctly with the faster switching characteristics.

Q: What is the moisture sensitivity level for both parts?

A: Both the IXDI509SIA and IXDI609SIA carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.
