Key Parameters

Substitute Part Grouping Explanation

Substitution of the IR2175SPBF is determined by strict equivalence across the following critical parameters:

• Electrical Performance: Current sensing accuracy (±0.5%), output current (20mA), input voltage range (9.5V ~ 20V), and operating temperature range (-40°C ~ 125°C) must remain identical
• Package Compatibility: 8-SOIC surface mount package with 0.154" (3.90mm) width ensures mechanical and electrical compatibility with existing PCB layouts
• Functional Classification: Current Sense function classification must be maintained
• Compliance Standards: RoHS3 compliance and MSL rating (2, 1 Year) must be preserved

The IR2175STRPBF qualifies as a direct substitute based on identical electrical specifications and package requirements. The primary distinction is packaging format: the substitute is supplied in Tape & Reel (TR) configuration versus the original Tube packaging.

Parameter Comparison

Engineering Selection Recommendations

The IR2175STRPBF is a qualified substitute for the IR2175SPBF based on identical electrical specifications, functional performance, and package compatibility. Both parts share the same base product number (IR2175) and maintain equivalent current sensing accuracy, voltage operating range, and temperature specifications.

The IR2175SPBF is classified as Obsolete, while the IR2175STRPBF maintains Active product status. This status difference reflects manufacturing lifecycle positioning and supply availability. Both parts maintain ROHS3 compliance and identical MSL ratings, ensuring regulatory and environmental compatibility.

The primary distinction between these parts is packaging format: Tube versus Tape & Reel (TR). This difference affects handling, storage, and automated assembly processes but does not impact electrical performance or functional equivalence. Selection between these formats should be based on production volume requirements and assembly line capabilities.

Frequently Asked Questions (FAQ)

Q: Can IR2175STRPBF replace IR2175SPBF in existing designs?

A: Yes. The IR2175STRPBF is electrically and functionally equivalent to the IR2175SPBF. Both parts deliver identical current sensing accuracy (±0.5%), output current (20mA), input voltage range (9.5V ~ 20V), and operating temperature performance (-40°C ~ 125°C). The 8-SOIC package dimensions are identical, ensuring PCB layout compatibility.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging supplies components in plastic tubes suitable for manual handling and lower-volume applications. Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, optimized for automated pick-and-place assembly equipment and higher production volumes. Electrical and functional performance is identical between packaging formats.

Q: Are both parts RoHS compliant?

A: Yes. Both the IR2175SPBF and IR2175STRPBF are ROHS3 compliant and carry identical Moisture Sensitivity Level (MSL) ratings of 2 (1 Year), ensuring equivalent environmental and regulatory compliance.

Q: Why is IR2175SPBF listed as Obsolete?

A: Product status reflects the manufacturer's lifecycle positioning. The IR2175SPBF is no longer in active production, while the IR2175STRPBF maintains Active status. For new designs or ongoing production, the IR2175STRPBF is the recommended source for this current sensing function.

Q: Are there any performance differences between these parts?

A: No. Both parts are manufactured by Infineon Technologies and share identical electrical specifications, accuracy ratings, and functional performance. Differences are limited to packaging format and product lifecycle status.
