MAX268BENG Band Pass Filter IC Equivalent & Substitute Parts

Part Overview

The MAX268BENG is a band pass filter integrated circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for signal conditioning applications requiring 140kHz center frequency filtering. This device implements a 2nd-order band pass filter topology in a 24-pin DIP package suitable for through-hole PCB assembly.

The MAX268BENG is classified as obsolete product status. Identifying equivalent and substitute parts is necessary to support legacy system maintenance, design updates, and procurement continuity when original inventory becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX268BENG is determined by the following critical parameters:

• Filter topology and order (2nd-order band pass)
• Center frequency specification (140kHz)
• Dual filter configuration (2 filters per IC)
• Supply voltage range compatibility (4.74V ~ 12.6V, ±2.37V ~ 6.3V)
• Physical package format (24-DIP through-hole)
• Pin-to-pin functional equivalence

The MAX268BENG+ qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is product status and compliance certification level.

Parameter Comparison

Engineering Selection Recommendations

The MAX268BENG+ is the direct substitute for MAX268BENG applications. Both parts share identical electrical and mechanical specifications, ensuring functional compatibility in existing circuit designs without modification.

The MAX268BENG+ offers the advantage of active product status, indicating ongoing manufacturer support and availability. Additionally, the MAX268BENG+ meets ROHS3 compliance requirements, whereas the original MAX268BENG is RoHS non-compliant. This distinction is relevant for applications subject to environmental or regulatory compliance mandates.

Both parts maintain equivalent moisture sensitivity levels and REACH/ECCN classifications, confirming compatibility for supply chain and regulatory purposes.

Frequently Asked Questions (FAQ)

Q: Can MAX268BENG+ be used as a direct replacement for MAX268BENG?

A: Yes. The MAX268BENG+ is electrically and mechanically equivalent to the MAX268BENG. All filter specifications, supply voltage ranges, and package dimensions are identical. No circuit modifications are required.

Q: What is the difference between MAX268BENG and MAX268BENG+?

A: The primary differences are product status and RoHS compliance. The MAX268BENG is obsolete and RoHS non-compliant, while the MAX268BENG+ is active and ROHS3 compliant. Electrical performance and pinout are identical.

Q: Are there any package or pinout differences?

A: No. Both parts use the 24-DIP (0.300", 7.62mm) package with identical pinout and through-hole mounting configuration.

Q: What supply voltages are supported?

A: Both parts support dual supply operation: 4.74V ~ 12.6V single supply or ±2.37V ~ 6.3V dual supply configuration.

Q: Is the MAX268BENG+ suitable for new designs?

A: Yes. The MAX268BENG+ active product status and ROHS3 compliance make it appropriate for new design implementations requiring 140kHz band pass filtering in a 24-DIP package.
