IR2175STR Equivalent & Substitute Parts

Part Overview

The IR2175STR is a current sense regulator manufactured by Infineon Technologies, designed for power management applications requiring precise current monitoring. This 8-SOIC surface mount device delivers 20mA output with ±0.5% accuracy across an input voltage range of 9.5V to 20V and operates reliably from -40°C to 125°C.

The IR2175STR is classified as obsolete, making it necessary to identify equivalent substitute components for new designs and ongoing production requirements. The IR2175STRPBF provides a direct parametric equivalent with active product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IR2175STR is determined by strict equivalence across the following critical parameters:

• Functional equivalence: Both parts perform current sense regulation with identical output current (20mA) and accuracy specification (±0.5%)
• Electrical compatibility: Input voltage range (9.5V ~ 20V) and operating temperature range (-40°C ~ 125°C) are identical
• Package compatibility: Both parts use 8-SOIC surface mount packaging with identical physical dimensions (0.154", 3.90mm Width)
• Manufacturer consistency: Both parts are manufactured by Infineon Technologies under the same base product number (IR2175)

The IR2175STRPBF qualifies as a direct parametric equivalent based on these criteria. The primary distinction is packaging format (Tape & Reel versus bulk) and product lifecycle status.

Engineering Selection Recommendations

The IR2175STRPBF is the direct substitute for the IR2175STR based on identical electrical and mechanical specifications. Selection of the IR2175STRPBF is supported by the following factors:

• Active product status: The IR2175STRPBF maintains active manufacturing status, ensuring long-term availability and supply chain continuity
• Regulatory compliance: The IR2175STRPBF meets ROHS3 compliance requirements, whereas the IR2175STR is non-compliant
• Packaging format: The Tape & Reel packaging of the IR2175STRPBF is standard for automated assembly processes in production environments
• Moisture sensitivity: The IR2175STRPBF specifies MSL 2 (1 Year), providing adequate protection for standard storage and handling conditions

For applications requiring the IR2175STR, the IR2175STRPBF provides complete functional and mechanical interchangeability with improved compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the IR2175STRPBF directly replace the IR2175STR in existing designs?

A: Yes. The IR2175STRPBF is electrically and mechanically identical to the IR2175STR. Both devices share identical input voltage range (9.5V ~ 20V), output current (20mA), accuracy (±0.5%), operating temperature range (-40°C ~ 125°C), and 8-SOIC package dimensions. No circuit modifications are required.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The IR2175STR is classified as obsolete, indicating Infineon has discontinued manufacturing and support. The IR2175STRPBF maintains active status, ensuring continued availability, technical support, and compliance with current manufacturing standards.

Q: How do the packaging formats differ between these parts?

A: The IR2175STR is supplied in bulk packaging, while the IR2175STRPBF is supplied in Tape & Reel (TR) format. Tape & Reel packaging is optimized for automated pick-and-place assembly and is the standard format for production environments. Bulk packaging is typically used for prototype or low-volume applications.

Q: What is the impact of the RoHS compliance difference?

A: The IR2175STR is RoHS non-compliant, while the IR2175STRPBF is ROHS3 compliant. ROHS3 compliance is required for products sold in the European Union and is increasingly mandated by OEMs globally. For new designs and production, the IR2175STRPBF is the appropriate selection.

Q: Are there any differences in moisture sensitivity handling?

A: The IR2175STR specifies MSL 1 (Unlimited), while the IR2175STRPBF specifies MSL 2 (1 Year). MSL 2 requires storage in controlled humidity conditions and use within one year of packaging. Standard industrial storage practices accommodate MSL 2 requirements without additional complexity.

Q: Are both parts subject to the same export classifications?

A: Yes. Both the IR2175STR and IR2175STRPBF share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, indicating no difference in export control or tariff treatment.
