MAX281BCWE+ Equivalent & Substitute Parts

Part Overview

The MAX281BCWE+ is a Bessel, Low Pass Switched Capacitor Filter IC manufactured by Analog Devices Inc./Maxim Integrated. This 5th order filter operates at a 20kHz cutoff frequency and is housed in a 16-SOIC surface mount package. The device is classified as Active product status with full ROHS3 compliance and unlimited moisture sensitivity rating. Alternative components are evaluated when supply constraints, lead time requirements, or specific application parameters necessitate component substitution within the same functional category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX281BCWE+ is determined by strict alignment with the following critical parameters:

• Filter Topology: Bessel, Low Pass Switched Capacitor architecture
• Cutoff Frequency: 20kHz nominal operation
• Filter Order: 5th order response
• Package Type: 16-SOIC surface mount form factor
• Supply Voltage Range: 4.75V ~ 16V, ±2.375V ~ 8V dual supply capability
• Product Status: Active manufacturing status
• Compliance: ROHS3 compliance requirement

Only components matching all specified parameters within the provided input data qualify as direct substitutes. The MAX281BCWE+ represents the current direct equivalent with identical electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the MAX281BCWE+?

A: A valid substitute must match the Bessel, Low Pass Switched Capacitor filter topology, operate at 20kHz cutoff frequency, provide 5th order filtering, support the specified 4.75V ~ 16V and ±2.375V ~ 8V supply ranges, and be packaged in 16-SOIC surface mount configuration with ROHS3 compliance.

Q: Can the MAX281BCWE+ be replaced with a different filter order or cutoff frequency?

A: No. The 5th order response and 20kHz cutoff frequency are fundamental to the device function. Substitution requires matching these exact specifications.

Q: Is the 16-SOIC package interchangeable with other package types?

A: No. The 16-SOIC (0.295", 7.50mm Width) package is specific to this device. Alternative packages require complete circuit redesign and PCB layout modification.

Q: What is the significance of MSL Level 1 rating?

A: MSL Level 1 indicates unlimited moisture sensitivity, meaning the component has no moisture-related shelf life restrictions and does not require special storage or handling procedures.

Q: Are there supply voltage flexibility options?

A: The MAX281BCWE+ supports dual supply operation (±2.375V ~ 8V) or single supply operation (4.75V ~ 16V). Circuit design must accommodate the selected supply configuration; substitutes must support the same voltage ranges.
