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 filter channels in a 28-SOIC surface mount package. The device is classified as Active product status and maintains full ROHS3 compliance with REACH unaffected designation. Finding equivalent parts is necessary when addressing supply chain constraints, inventory availability, or specific procurement requirements while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MAX274ACWI+ is determined by strict equivalence across the following critical parameters:

• Filter Architecture: Continuous, band pass low pass configuration with 8th order response
• Frequency Specification: 150kHz cutoff or center frequency
• Channel Count: Four independent filter channels
• Package Specification: 28-SOIC surface mount package with 0.295" (7.50mm) width
• Supply Voltage Range: 4.74V ~ 11V and ±2.37V ~ 5.5V dual supply capability
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

Only parts meeting all these parameters qualify as direct substitutes. No parameter relaxation or functional compromise is acceptable in equivalent part selection.

Parameter Comparison

Engineering Selection Recommendations

The MAX274ACWI+ maintains Active product status with full regulatory compliance under ROHS3 and REACH unaffected classifications. Component selection should prioritize parts with identical certifications and compliance designations to ensure regulatory continuity in end-use applications. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling. Surface mount 28-SOIC packaging requires compatible PCB footprints and reflow soldering processes. Dual supply voltage capability (4.74V ~ 11V and ±2.37V ~ 5.5V) must align with circuit design requirements.

Frequently Asked Questions (FAQ)

Q: What makes a part a direct substitute for the MAX274ACWI+?

A: A direct substitute must match all electrical and mechanical parameters: 8th order continuous band pass low pass filter architecture, 150kHz frequency specification, four filter channels, 28-SOIC package, dual supply voltage range, and identical regulatory compliance status.

Q: Can I use a different filter order or frequency specification?

A: No. The filter order and cutoff frequency are fundamental to circuit performance. Substitution requires exact parameter matching.

Q: Are there packaging alternatives for this device?

A: The MAX274ACWI+ is specified for 28-SOIC surface mount package only. Alternative packages would constitute a different part number and require separate qualification.

Q: What is the significance of the MSL rating?

A: MSL 1 (Unlimited) indicates this component has no moisture sensitivity limitations. Standard storage and handling procedures apply without special desiccant or humidity control requirements.

Q: Does ROHS3 compliance affect substitution criteria?

A: Yes. All substitute parts must maintain ROHS3 compliance to ensure regulatory continuity in applications subject to RoHS directives.

Q: Can I substitute based on functional similarity alone?

A: No. Substitution requires strict parameter equivalence across electrical specifications, package dimensions, supply voltage ranges, and regulatory certifications. Functional similarity without exact parameter matching is not acceptable for component selection.
