IPS021 Equivalent & Substitute Parts

Part Overview

The IPS021 is a Power Management IC (PMIC) manufactured by Infineon Technologies, classified as a Power Switch/Driver with 1:1 N-Channel configuration. This through-hole TO-220AB component delivers 1.8A maximum output current with low-side N-channel switching capability and integrated current limiting and over-temperature protection. The IPS021 is currently listed as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations where this component is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the IPS021 requires matching the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Functional classification: Power Switch/Driver with 1:1 ratio, low-side N-channel output configuration
• Package compatibility: TO-220-3 through-hole mounting
• Output current capability: Minimum 1.8A
• Load voltage rating: Minimum 35V
• Fault protection: Current limiting and over-temperature protection
• Operating temperature range: Support for -40°C to 150°C minimum

Substitution Categories:

The available alternatives fall into two distinct functional groups:

1. Direct PMIC Substitutes (Recommended for Direct Replacement): Parts maintaining identical PMIC classification, 1:1 ratio, low-side N-channel configuration, and TO-220 package family. These preserve the original circuit topology and control interface.

2. Thyristor-Based Alternatives (Functional Equivalents with Design Considerations): Parts offering power switching capability in TO-220-3 package with higher current and voltage ratings. These require circuit topology evaluation due to different control mechanisms (TRIAC vs. MOSFET driver).

Engineering Selection Recommendations

VND1NV04-E (STMicroelectronics): This part is the primary recommended substitute for direct functional replacement. It maintains identical PMIC classification, 1:1 ratio, low-side N-channel output configuration, and equivalent electrical performance (1.7A output current, 36V load voltage rating, 130mOhm typical on-state resistance). The VND1NV04-E is currently in active production status with ROHS3 compliance. The primary design consideration is package transition from through-hole TO-220-3 to surface-mount DPAK (TO-252-3), which requires PCB layout modification. Operating temperature range matches the IPS021 specification (-40°C to 150°C). The VND1NV04-E includes additional over-voltage protection compared to the original part.

AVS10CB and AVS08CB (STMicroelectronics): These thyristor-based alternatives provide power switching capability in TO-220-3 through-hole package with significantly higher current ratings (8A and 5A respectively) and voltage ratings (600V and 500V respectively). Both parts are currently in active production with ROHS3 compliance. These alternatives are functionally equivalent for applications requiring AC or DC power switching but operate on different control principles (TRIAC vs. MOSFET driver). Circuit topology evaluation is required to confirm compatibility, as the control interface and switching characteristics differ from the original IPS021. Operating temperature ranges are reduced compared to the IPS021 (0°C to 125°C for AVS10CB, -10°C to 125°C for AVS08CB).

Frequently Asked Questions (FAQ)

Q: Can the VND1NV04-E directly replace the IPS021 in existing PCB designs?

A: The VND1NV04-E provides electrical equivalence but requires PCB layout modification due to package change from through-hole TO-220-3 to surface-mount DPAK. Pin configuration and electrical function are compatible; however, mounting footprint redesign is necessary.

Q: What are the key differences between the PMIC substitute (VND1NV04-E) and the thyristor alternatives (AVS10CB, AVS08CB)?

A: The VND1NV04-E maintains identical PMIC architecture and control interface as the IPS021, requiring no circuit topology changes. The thyristor alternatives (AVS10CB, AVS08CB) operate on different switching principles and may require circuit redesign depending on the original application's control requirements. PMIC substitutes are recommended for direct replacement scenarios.

Q: Are the AVS10CB and AVS08CB suitable for all IPS021 applications?

A: The AVS10CB and AVS08CB provide power switching capability in compatible TO-220-3 packages with higher current and voltage ratings. However, these are thyristor-based components with different control characteristics than the original MOSFET driver. Application compatibility depends on circuit topology and control signal requirements. Engineering evaluation is required.

Q: What compliance considerations apply to substitution?

A: The IPS021 is RoHS non-compliant. All recommended substitutes (VND1NV04-E, AVS10CB, AVS08CB) are ROHS3 compliant, making them suitable for new designs and applications with RoHS compliance requirements. Existing legacy systems using the IPS021 may continue operation without compliance impact.

Q: How do operating temperature ranges compare?

A: The IPS021 operates from -40°C to 150°C. The VND1NV04-E matches this range exactly. The thyristor alternatives operate within reduced ranges: AVS10CB from 0°C to 125°C and AVS08CB from -10°C to 125°C. Applications requiring full -40°C to 150°C operation should prioritize the VND1NV04-E.

Q: What is the impact of on-state resistance differences?

A: The IPS021 specifies 130mOhm typical on-state resistance. The VND1NV04-E specifies 250mOhm maximum, representing approximately 92% higher resistance. This affects power dissipation and thermal performance in current-limited applications. Thermal analysis is recommended for high-current or continuous-duty applications.
