IR2175S Equivalent & Substitute Parts

Part Overview

The IR2175S 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 IR2175S is classified as obsolete. Identifying equivalent and substitute parts is essential for maintaining design continuity, ensuring supply chain reliability, and supporting long-term product availability in applications where this component is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IR2175S is determined by strict equivalence across the following critical parameters:

• Functional equivalence: Current sense regulator function
• Electrical specifications: ±0.5% accuracy, 20mA output, 9.5V ~ 20V input range, -40°C ~ 125°C operating temperature
• Package compatibility: 8-SOIC form factor with identical 0.154" (3.90mm) width
• Manufacturer consistency: Infineon Technologies

The IR2175SPBF qualifies as a direct substitute based on identical electrical performance, package specification, and manufacturer origin. Both parts share the same base product number (IR2175) and deliver equivalent current sensing functionality within specified tolerances.

Parameter Comparison

Engineering Selection Recommendations

The IR2175SPBF is electrically and mechanically equivalent to the IR2175S, with identical current sensing performance and package specifications. The primary distinction lies in regulatory compliance: the IR2175SPBF meets ROHS3 requirements, whereas the IR2175S does not.

For applications subject to RoHS3 compliance mandates, the IR2175SPBF is the appropriate selection. Both parts are classified as obsolete; component selection should prioritize available inventory and application-specific compliance requirements.

The IR2175SPBF carries a Moisture Sensitivity Level of 2 (1 Year) compared to the IR2175S MSL of 1 (Unlimited), requiring adherence to moisture control protocols during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can IR2175SPBF replace IR2175S in existing designs?

A: Yes. Both parts deliver identical electrical performance (±0.5% accuracy, 20mA output, 9.5V ~ 20V input) and use the same 8-SOIC package. Functional substitution is direct. Compliance requirements and moisture handling procedures should be evaluated for your specific application.

Q: What is the difference between IR2175S and IR2175SPBF?

A: The parts are electrically and mechanically identical. The IR2175SPBF is ROHS3 compliant, while the IR2175S is not. The IR2175SPBF has a Moisture Sensitivity Level of 2 (1 Year), requiring controlled storage conditions, whereas the IR2175S has MSL 1 (Unlimited).

Q: Are both parts still available?

A: Both the IR2175S and IR2175SPBF are classified as obsolete products. Availability is limited to existing inventory. The IR2175SPBF currently has 1555 units in stock, while the IR2175S has 3292 units available.

Q: Does the 8-SOIC package remain consistent between these parts?

A: Yes. Both parts use the identical 8-SOIC package with 0.154" (3.90mm) width, ensuring direct PCB compatibility without layout modifications.

Q: What compliance certifications apply to these parts?

A: Both parts carry REACH Unaffected and EAR99 ECCN classifications. The IR2175SPBF additionally meets ROHS3 compliance requirements. The IR2175S does not carry RoHS certification.
