MAX274ACWI Equivalent & Substitute Parts

Part Overview

The MAX274ACWI 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 classified as obsolete, making identification of compatible alternatives essential for ongoing system support and new design implementations. Substitute parts must maintain identical electrical performance and mechanical compatibility while offering improved availability or compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX274ACWI 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
• Moisture Sensitivity Level: 1 (Unlimited)

The MAX274ACWI+ qualifies as a direct substitute, maintaining identical electrical specifications and mechanical form factor while offering improved product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The MAX274ACWI+ is the direct equivalent substitute for the MAX274ACWI. Both parts share identical electrical and mechanical specifications, ensuring pin-for-pin compatibility and functional interchangeability in circuit applications.

The MAX274ACWI+ offers two significant advantages over the original part:

1. Active Product Status: The MAX274ACWI+ maintains active production status, ensuring long-term availability and supply chain reliability compared to the obsolete MAX274ACWI.

2. Regulatory Compliance: The MAX274ACWI+ is ROHS3 compliant, meeting current environmental and hazardous substance restrictions, whereas the MAX274ACWI is RoHS non-compliant.

For new designs or system refreshes, the MAX274ACWI+ is the appropriate selection. For legacy system maintenance requiring exact part matching, the MAX274ACWI remains functionally equivalent where supply permits.

Frequently Asked Questions (FAQ)

Q: Can MAX274ACWI+ be used as a direct replacement for MAX274ACWI in existing designs?

A: Yes. The MAX274ACWI+ is electrically and mechanically identical to the MAX274ACWI. All electrical parameters, pin configurations, and package dimensions are equivalent, enabling direct substitution without circuit modification.

Q: What is the difference between MAX274ACWI and MAX274ACWI+?

A: The parts are functionally identical. The primary differences are product status (Active vs. Obsolete) and RoHS compliance (ROHS3 Compliant vs. RoHS non-compliant). The MAX274ACWI+ is supplied in Tube packaging, while the original part packaging is not specified.

Q: Are there any compatibility concerns with the 28-SOIC package?

A: No. Both parts use the identical 28-SOIC (0.295", 7.50mm Width) package. PCB footprints, reflow profiles, and assembly processes remain unchanged.

Q: Does the MAX274ACWI+ support the same supply voltage range?

A: Yes. Both parts operate across the identical supply voltage range of 4.74V ~ 11V and ±2.37V ~ 5.5V, ensuring compatibility with existing power supply designs.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: Both the MAX274ACWI and MAX274ACWI+ have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
