Parameter Comparison

Engineering Selection Recommendations

The IR2175STRPBF is the manufacturer-recommended substitute for the obsolete IR2172SPBF. Both components are manufactured by Infineon Technologies and share identical electrical specifications for input voltage, output current, and operating temperature range. Both are packaged in the same 8-SOIC form factor and meet ROHS3 compliance requirements.

The IR2175STRPBF offers active product status, ensuring long-term availability and supply chain continuity. The component is supplied in Tape & Reel packaging, suitable for automated assembly processes. Both parts maintain equivalent moisture sensitivity levels and REACH compliance status.

Selection of the IR2175STRPBF eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the IR2175STRPBF be used as a direct replacement for the IR2172SPBF?

A: Yes. Both components share identical input voltage range (9.5V ~ 20V), output current (20mA), operating temperature range (-40°C ~ 125°C), and 8-SOIC package specifications. Pin-to-pin compatibility is maintained.

Q: What is the primary difference between these two parts?

A: The IR2172SPBF is obsolete, while the IR2175STRPBF maintains active product status. The IR2175STRPBF specifies ±0.5% accuracy, whereas the IR2172SPBF does not provide an accuracy specification. The IR2175STRPBF is supplied in Tape & Reel packaging for automated assembly.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 2, 1 Year). No compliance differences exist between the two components.

Q: Does the package footprint remain the same?

A: Yes. Both components use the 8-SOIC package with 0.154" width (3.90mm). PCB layout and footprint designs require no modification.

Q: Is the IR2175STRPBF available in bulk packaging?

A: The IR2175STRPBF is supplied in Tape & Reel (TR) packaging. For bulk quantities or alternative packaging options, contact your component supplier directly.
