Parameter Comparison

Engineering Selection Recommendations

The MAX4172ESA+T is the direct substitute for the MAX4172ESA-T based on complete electrical and mechanical parameter equivalence. All critical specifications including bandwidth, bias current, input offset voltage, supply current, output current, supply voltage range, and operating temperature are identical.

The primary distinction between these parts is product status: the MAX4172ESA-T is obsolete, while the MAX4172ESA+T maintains active status with significantly higher inventory availability (40,114 pieces versus 813 pieces). Both parts share identical RoHS3 compliance, MSL rating, and REACH status.

The MAX4172ESA+T is offered in Cut Tape (CT) and Digi-Reel® packaging formats, providing flexibility for both prototype and production volume requirements. The 8-SOIC surface mount package remains consistent, ensuring direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can MAX4172ESA+T replace MAX4172ESA-T in existing designs?

A: Yes. The MAX4172ESA+T is electrically and mechanically equivalent to the MAX4172ESA-T across all specified parameters. No circuit modifications or PCB redesign is required.

Q: What is the difference between MAX4172ESA-T and MAX4172ESA+T?
