IPS031 Equivalent & Substitute Parts

Part Overview

The IPS031 is a Power Management Integrated Circuit (PMIC) manufactured by Infineon Technologies, classified as a Power Switch/Driver with 1:1 N-Channel configuration rated at 3.1A in TO-220AB packaging. This component functions as a general-purpose low-side N-channel switch with on/off interface control, designed for applications requiring load switching up to 35V maximum.

The IPS031 is currently listed as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement. Substitute components must maintain compatibility with the original electrical specifications and through-hole TO-220-3 package format.

Key Parameters

Substitute Part Grouping Explanation

The IPS031 has been identified with two substitute components: AVS08CB and AVS10CB, both manufactured by STMicroelectronics and classified as Thyristors (TRIAC - Internally Triggered devices).

Substitution logic is based on the following critical parameters:

• Package compatibility: TO-220-3 through-hole format maintained across all parts
• Voltage rating: Substitute parts rated at 500V (AVS08CB) and 600V (AVS10CB) exceed the IPS031 maximum load voltage of 35V
• Current capacity: AVS08CB rated at 5A and AVS10CB rated at 8A both exceed the IPS031 output current of 3.1A
• Configuration: Single output configuration maintained
• Mounting: Through-hole mounting preserved
• Product status: Both substitutes are Active, addressing the obsolescence of the IPS031

The substitution relationship indicates functional equivalence within the specified electrical and mechanical constraints for this product category.

Parameter Comparison

Engineering Selection Recommendations

Selection between AVS08CB and AVS10CB substitutes should be based on the following criteria:

AVS08CB (STMicroelectronics): Suitable for applications where the 500V voltage rating and 5A current capacity are sufficient. This part is ROHS3 compliant and maintains an operating temperature range of -10°C to 125°C. Recommended for standard industrial applications with moderate thermal requirements.

AVS10CB (STMicroelectronics): Recommended for applications requiring higher voltage margin (600V rating) and increased current capacity (8A). This part is ROHS3 compliant and operates across 0°C to 125°C. Suitable for demanding applications where additional headroom in electrical specifications is beneficial.

Both substitutes address the obsolescence of the IPS031 and provide improved compliance status through ROHS3 certification. The choice between them depends on specific application voltage and current requirements within the design envelope.

Frequently Asked Questions (FAQ)

Q: Why is the IPS031 being replaced? A: The IPS031 is classified as obsolete by Infineon Technologies. AVS08CB and AVS10CB are active products from STMicroelectronics that provide functional equivalence with improved compliance status.

Q: Are the substitute parts pin-compatible with the IPS031? A: All three components share the TO-220-3 package format and through-hole mounting type, ensuring mechanical compatibility. Pin assignment verification against specific application schematics is required for electrical compatibility confirmation.

Q: What is the voltage rating difference between substitutes? A: AVS08CB is rated at 500V off-state voltage, while AVS10CB is rated at 600V off-state voltage. Both exceed the IPS031 maximum load voltage of 35V. Selection depends on application-specific voltage margin requirements.

Q: Do the substitutes support the same current levels as the IPS031? A: AVS08CB supports 5A on-state current and AVS10CB supports 8A on-state current, both exceeding the IPS031 specification of 3.1A maximum output current.

Q: What is the operating temperature range difference? A: The IPS031 operates from -40°C to 150°C. AVS08CB operates from -10°C to 125°C, and AVS10CB operates from 0°C to 125°C. Application thermal requirements must be evaluated against these ranges.

Q: Are the substitutes RoHS compliant? A: Both AVS08CB and AVS10CB are ROHS3 compliant, providing improved environmental compliance compared to the IPS031, which is RoHS non-compliant.
