MAX274BC/D Equivalent & Substitute Parts

Part Overview

The MAX274BC/D is a 4th- and 8th-order continuous-time band pass and low pass filter integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. This component operates at a cutoff/center frequency of 150kHz and integrates four independent filters in a die package format. The MAX274BC/D is classified as obsolete, which necessitates identification of active equivalent components for new designs and ongoing production requirements. Substitute parts must maintain functional equivalence across filter topology, frequency response, and electrical specifications to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX274BC/D is determined by strict equivalence across the following critical parameters:

Functional Parameters:

• Filter topology: Continuous, band pass and low pass configuration
• Filter order: 8th order
• Number of integrated filters: 4 channels
• Frequency specification: 150kHz cutoff/center frequency

Electrical Parameters:

• Supply voltage range: 4.74V ~ 11V and ±2.37V ~ 5.5V dual supply capability
• Surface mount technology requirement

Compliance Parameters:

• RoHS3 compliance
• MSL rating of 1 (Unlimited)

The MAX274AEWI+ qualifies as a direct substitute because it maintains identical functional specifications, electrical characteristics, and compliance certifications. The primary distinction is packaging format: the MAX274BC/D is supplied as a die, while the MAX274AEWI+ is packaged in 28-SOIC form factor, which represents a standard surface mount package suitable for production assembly.

Parameter Comparison

Engineering Selection Recommendations

The MAX274AEWI+ is the active equivalent for the obsolete MAX274BC/D. Selection of this substitute is based on the following engineering criteria:

Product Status Alignment: The MAX274BC/D is obsolete and no longer manufactured. The MAX274AEWI+ maintains active production status, ensuring long-term availability and supply chain continuity.

Functional Equivalence: Both components share identical filter specifications: 8th-order continuous-time band pass and low pass topology with four integrated filters operating at 150kHz. Electrical performance characteristics, including supply voltage ranges and signal processing capabilities, are equivalent.

Compliance Certification: Both components maintain ROHS3 compliance and MSL rating of 1 (Unlimited), satisfying environmental and reliability requirements for production and field deployment.

Package Consideration: The transition from die package (MAX274BC/D) to 28-SOIC package (MAX274AEWI+) represents a standard manufacturing format change. The 28-SOIC package is suitable for automated surface mount assembly and provides standard PCB integration methodology.

Frequently Asked Questions (FAQ)

Q: Can the MAX274AEWI+ directly replace the MAX274BC/D in existing designs?

A: The MAX274AEWI+ provides functional equivalence in filter performance and electrical specifications. The primary design consideration is package format: the MAX274BC/D is a die requiring hybrid assembly, while the MAX274AEWI+ is a 28-SOIC package suitable for standard PCB assembly. Circuit-level compatibility is maintained across all electrical parameters.

Q: What are the key parameters that define substitution eligibility for the MAX274BC/D?

A: Substitution eligibility is determined by: filter topology (continuous, band pass and low pass), filter order (8th), number of filters (4), frequency specification (150kHz), supply voltage range (4.74V ~ 11V, ±2.37V ~ 5.5V), and compliance certifications (ROHS3, MSL 1). Any substitute must maintain all these parameters.

Q: Are there compliance or environmental differences between these components?

A: Both the MAX274BC/D and MAX274AEWI+ are ROHS3 compliant and carry MSL rating of 1 (Unlimited). No environmental or regulatory differences exist between these components.

Q: What is the significance of the package format difference?

A: The MAX274BC/D die package requires hybrid circuit assembly techniques, while the MAX274AEWI+ 28-SOIC package is compatible with standard surface mount assembly processes. For new production designs, the 28-SOIC format provides manufacturing efficiency and cost optimization.

Q: Is the MAX274AEWI+ the only active substitute available?

A: Based on the provided substitute list, the MAX274AEWI+ is the identified active equivalent for the MAX274BC/D. This component maintains all functional and electrical specifications required for direct substitution.
