MAX274BCNG Equivalent & Substitute Parts

Part Overview

The MAX274BCNG 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 24-DIP through-hole package. The part is classified as obsolete, making identification of suitable substitutes essential for ongoing system support and new design implementations where this filter topology is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX274BCNG is determined by strict equivalence across the following critical parameters:

• Filter Topology: Continuous, band pass low pass configuration
• Frequency Specification: 150kHz cutoff or center frequency
• Filter Architecture: 8th order with four independent filter channels
• Electrical Interface: Supply voltage range 4.74V ~ 11V and ±2.37V ~ 5.5V
• Physical Form Factor: 24-DIP through-hole package (0.300", 7.62mm)

Only parts matching all these parameters across electrical, functional, and mechanical dimensions qualify as direct substitutes. The MAX274BCNG+ meets these criteria while offering improved product status and compliance posture.

Parameter Comparison

Engineering Selection Recommendations

The MAX274BCNG+ is the direct substitute for the MAX274BCNG. Both parts are electrically and mechanically identical across all functional parameters. The primary distinction is product lifecycle status: the MAX274BCNG is obsolete while the MAX274BCNG+ maintains active status with current manufacturing support.

The MAX274BCNG+ additionally provides ROHS3 compliance, addressing regulatory requirements for new designs and systems subject to RoHS directives. Both parts maintain identical MSL ratings and REACH status, ensuring equivalent handling and environmental compliance profiles.

For applications requiring the MAX274BCNG, the MAX274BCNG+ is the appropriate selection for continued component availability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Are MAX274BCNG and MAX274BCNG+ electrically interchangeable?

Q: What is the difference between MAX274BCNG and MAX274BCNG+?

A: The parts are functionally equivalent. The MAX274BCNG+ is the active production variant with ROHS3 compliance, while the MAX274BCNG is obsolete. Packaging differs: MAX274BCNG ships in bulk, MAX274BCNG+ in tube format.

Q: Can I use MAX274BCNG+ in existing designs specified for MAX274BCNG?

A: Yes. The MAX274BCNG+ is a direct substitute with identical electrical and mechanical specifications. No design changes are necessary.

Q: What is the 24-DIP package specification?

A: The 24-DIP package is a through-hole dual inline package measuring 0.300 inches (7.62mm) in width, suitable for PCB mounting with standard DIP sockets or direct soldering.

Q: Does the packaging format affect electrical performance?

A: No. Packaging format (bulk versus tube) does not affect component electrical characteristics or performance. It impacts only handling, storage, and logistics.

Q: Are there RoHS compliance differences between these parts?

A: Yes. The MAX274BCNG is RoHS non-compliant, while MAX274BCNG+ is ROHS3 compliant. For applications subject to RoHS regulations, MAX274BCNG+ is required.
