IR5001STRPBF Equivalent & Substitute Parts

Part Overview

The IR5001STRPBF is an N+1 ORing Controller manufactured by Infineon Technologies, designed for distributed power systems operating at -48V. This component functions as a power management integrated circuit (PMIC) that manages OR-ing of multiple power sources in redundant power supply configurations. The IR5001STRPBF is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution of the IR5001STRPBF is determined by the following critical parameters:

• Functional Type: N+1 ORing Controller with N-Channel FET configuration
• Package Compatibility: 8-SOIC form factor with identical 0.154" (3.90mm) width
• Voltage Supply Range: Minimum 36V lower bound; upper bound tolerance of 75V or greater
• Delay Time Specifications: ON delay of 27 µs and OFF delay of 130 ns or lower
• Supply Current: 500 µA or lower
• Mounting Type: Surface Mount
• Input:Output Ratio: N:1 configuration
• Internal Switch Configuration: No internal switches

The LM5051MAE/NOPB from Texas Instruments meets all substitution criteria within these defined parameters.

Engineering Selection Recommendations

The LM5051MAE/NOPB is the manufacturer-recommended substitute for the obsolete IR5001STRPBF. Selection of this alternative is supported by the following factors:

Product Status: The IR5001STRPBF is classified as obsolete, whereas the LM5051MAE/NOPB maintains active product status with current manufacturing and distribution support.

Compliance & Certifications: The LM5051MAE/NOPB is ROHS3 compliant and carries REACH Unaffected status, meeting current regulatory requirements for electronic component procurement. Both parts share identical ECCN (EAR99) and HTSUS classifications.

Electrical Performance: The LM5051MAE/NOPB demonstrates equivalent or superior electrical characteristics across all measured parameters. Supply voltage range extends to 100V (versus 75V maximum for the IR5001STRPBF), OFF delay time is reduced to 120 ns (versus 130 ns), and supply current is reduced to 400 µA (versus 500 µA).

Thermal & Environmental Range: The LM5051MAE/NOPB operates across an extended temperature range of -40°C to 125°C, providing broader environmental compatibility compared to the 0°C to 85°C range of the IR5001STRPBF.

Package & Mounting: Both components utilize identical 8-SOIC packaging with 0.154" (3.90mm) width, ensuring direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can the LM5051MAE/NOPB directly replace the IR5001STRPBF in existing designs?

A: Yes. Both components share identical package geometry (8-SOIC), functional classification (N+1 ORing Controller), and electrical interface specifications. The LM5051MAE/NOPB demonstrates equivalent or improved performance across all critical parameters.

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

A: The primary differences are product status (obsolete versus active), supply voltage upper limit (75V versus 100V), OFF delay time (130 ns versus 120 ns), supply current (500 µA versus 400 µA), and operating temperature range (0°C–85°C versus -40°C–125°C). All differences favor the LM5051MAE/NOPB.

Q: Are there any packaging or mounting considerations?

A: No. Both parts use identical 8-SOIC surface mount packaging with matching dimensions. No PCB layout modifications are required for substitution.

Q: Does the LM5051MAE/NOPB meet current regulatory requirements?

A: Yes. The LM5051MAE/NOPB is ROHS3 compliant and carries REACH Unaffected status, meeting current electronic component procurement standards.

Q: What is the substitution basis for the LM5051MAE/NOPB?

A: Substitution is based on functional equivalence as an N+1 ORing Controller with N-Channel FET configuration, identical package form factor, compatible voltage and current specifications, and manufacturer recommendation. The LM5051MAE/NOPB meets or exceeds all electrical and mechanical parameters of the IR5001STRPBF.
