IPS1021PBF Equivalent & Substitute Parts

Part Overview

The IPS1021PBF is a Power Switch/Driver IC manufactured by Infineon Technologies, configured as a 1:1 N-Channel low-side switch rated for 14.6A maximum output current in a TO-220AB package. The device is classified as Obsolete, making substitute parts necessary for new designs and ongoing production requirements. Alternative components must maintain functional equivalence in switching topology, output configuration, and thermal management characteristics.

Substitute Part Grouping Explanation

Substitute parts for the IPS1021PBF are selected based on the following critical parameters that define functional equivalence:

Primary Substitution Criteria:

• Output Configuration: Low Side, N-Channel, 1:1 topology
• Package / Case: TO-220-3 form factor for direct PCB compatibility
• Mounting Type: Through Hole for identical assembly requirements
• Fault Protection: Current Limiting and Over Temperature protection
• Output Current Rating: Minimum 14.6A to meet or exceed original specification
• Load Voltage Rating: Minimum 28V to support original application voltage

Substitute Classification:

VNP20N07-E and VNP35N07-E (STMicroelectronics) are functionally equivalent Power Management ICs with identical output topology, package, and protection features. Both devices are Active status products with enhanced specifications including Status Flag output and Over Voltage protection. VNP20N07-E provides 14A output current with 50mOhm Rds On, while VNP35N07-E provides 25A output current with 280mOhm Rds On, both exceeding the 14.6A requirement of the original part.

AVS10CB (STMicroelectronics) is categorized as a TRIAC device with different functional topology (Internally Triggered, 600V, 8A) and does not meet the substitution criteria for low-side N-Channel power switch applications.

Parameter Comparison

Engineering Selection Recommendations

VNP20N07-E and VNP35N07-E are the qualified substitutes for IPS1021PBF applications. Both devices maintain identical TO-220-3 package geometry and through-hole mounting compatibility, ensuring direct PCB layout compatibility without redesign.

VNP20N07-E is recommended for applications requiring output current up to 14A with load voltages up to 55V. This device provides current and voltage specifications that directly exceed the IPS1021PBF requirements while maintaining similar thermal characteristics.

VNP35N07-E is recommended for applications requiring higher current capacity up to 25A. The increased Rds On specification (280mOhm Max) results in higher on-state power dissipation compared to VNP20N07-E and must be evaluated against thermal management capabilities of the application.

Both substitute devices are Active status products with ROHS3 compliance and REACH Unaffected certification, supporting current regulatory requirements. Enhanced protection features including Over Voltage detection provide additional system reliability compared to the original part.

Frequently Asked Questions (FAQ)

Q: Can VNP20N07-E or VNP35N07-E directly replace IPS1021PBF without PCB modifications?

A: Yes. Both substitute devices use identical TO-220-3 package and through-hole mounting configuration, enabling direct pin-for-pin replacement without PCB layout changes.

Q: What is the difference between VNP20N07-E and VNP35N07-E?

A: VNP20N07-E is rated for 14A maximum output current with 50mOhm Rds On (Max). VNP35N07-E is rated for 25A maximum output current with 280mOhm Rds On (Max). Selection depends on application current requirements and thermal management constraints.

Q: Are the substitute parts compatible with the original 28V load voltage specification?

A: Yes. Both VNP20N07-E and VNP35N07-E are rated for 55V maximum load voltage, exceeding the 28V requirement of IPS1021PBF.

Q: Why is AVS10CB not a suitable substitute?

A: AVS10CB is a TRIAC device with Internally Triggered topology, 600V off-state voltage, and 8A on-state current rating. This device does not match the low-side N-Channel power switch topology and current specifications required for IPS1021PBF replacement.

Q: What are the compliance differences between the original and substitute parts?

A: IPS1021PBF product status is Obsolete with unspecified RoHS compliance. VNP20N07-E and VNP35N07-E are Active status products with ROHS3 compliance certification, supporting current manufacturing and environmental regulations.

Q: How do the protection features compare?

A: IPS1021PBF provides Current Limiting (Fixed) and Over Temperature protection. VNP20N07-E and VNP35N07-E provide the same protections plus Over Voltage detection, offering enhanced system reliability.
