MAX274BCWI Equivalent & Substitute Parts

Part Overview

The MAX274BCWI is a continuous, band pass low pass filter IC manufactured by Analog Devices Inc./Maxim Integrated. This 8th order filter operates at a 150kHz cutoff frequency and integrates four independent filters in a 28-SOIC surface mount package. The device is currently classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX274BCWI is determined by strict equivalence across the following critical parameters:

• Filter Type: Continuous, Band Pass Low Pass
• Filter Order: 8th
• Frequency - Cutoff or Center: 150kHz
• Number of Filters: 4
• Voltage - Supply: 4.74V ~ 11V, ±2.37V ~ 5.5V
• Package / Case: 28-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount

The MAX274BCWI+ meets all electrical and mechanical substitution criteria. The primary distinction between these parts is product status and compliance certification, not functional performance or pin compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MAX274BCWI+ is a direct functional equivalent to the MAX274BCWI. Both parts share identical electrical specifications, filter characteristics, and package geometry. The MAX274BCWI+ is the preferred selection for new designs and ongoing production due to its active product status and ROHS3 compliance certification. For legacy systems currently using the MAX274BCWI, the MAX274BCWI+ provides pin-for-pin compatibility without circuit modification.
