MAX261BENG Equivalent & Substitute Parts

Part Overview

The MAX261BENG is a universal switched capacitor filter IC manufactured by Analog Devices Inc./Maxim Integrated. This component functions as a 2nd order universal switched capacitor filter with a 57kHz cutoff frequency, designed for signal conditioning and filtering applications in interface circuits. The MAX261BENG is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations. Active alternatives with identical electrical and mechanical specifications are available to ensure design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX261BENG is determined by strict equivalence across the following critical parameters:

• Filter Architecture: Universal switched capacitor topology
• Frequency Specification: 57kHz cutoff/center frequency
• Filter Configuration: 2nd order, dual filter channels
• Supply Voltage Range: 4.74V ~ 12.6V and ±2.37V ~ 6.3V
• Package Format: 24-DIP (0.300", 7.62mm) through-hole mounting
• Pin Compatibility: 24-PDIP supplier device package

The MAX261BENG+ qualifies as a direct substitute based on identical electrical performance specifications and mechanical compatibility. The primary distinction is product status and compliance certification, not functional or physical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The MAX261BENG+ is the direct functional equivalent of the MAX261BENG. Both parts share identical electrical specifications, filter characteristics, and physical packaging. Selection between these parts is determined by regulatory and supply chain requirements rather than technical performance.

The MAX261BENG+ is recommended for new designs and ongoing production due to its active product status and ROHS3 compliance certification. The MAX261BENG remains suitable for legacy system maintenance where existing inventory is available and RoHS compliance is not a design requirement.

Frequently Asked Questions (FAQ)

Q: Can MAX261BENG+ be used as a direct replacement for MAX261BENG in existing designs?

A: Yes. The MAX261BENG+ is electrically and mechanically identical to the MAX261BENG. Both parts feature the same 57kHz universal switched capacitor filter topology, 2nd order configuration, dual filter channels, supply voltage range, and 24-DIP package format. Pin-for-pin compatibility is complete.

Q: What is the primary difference between MAX261BENG and MAX261BENG+?

A: The MAX261BENG+ is an active product with ROHS3 compliance certification, while the MAX261BENG is obsolete and RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there any package or mounting differences between these parts?

A: No. Both parts use 24-DIP (0.300", 7.62mm) through-hole packaging with identical pin configurations and mechanical dimensions.

Q: What supply voltage range does the MAX261BENG support?

A: The MAX261BENG supports dual supply voltages: 4.74V ~ 12.6V (single supply) and ±2.37V ~ 6.3V (dual supply).

Q: Is the MAX261BENG+ suitable for applications requiring RoHS compliance?

A: Yes. The MAX261BENG+ is ROHS3 compliant and suitable for designs with RoHS regulatory requirements.
