MAX271CWG+ Equivalent & Substitute Parts Reference

Part Overview

The MAX271CWG+ is a continuous low pass filter integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. This 2nd order filter operates at a 25kHz cutoff frequency and is housed in a 24-SOIC surface mount package. The device is currently in active production status with 923 units available in new original inventory. The MAX271CWG+ is essential in signal conditioning applications where precise low pass filtering at 25kHz is required. Alternative equivalent parts may be necessary due to supply chain constraints, regional availability, or specific procurement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX271CWG+ is determined by strict equivalence across the following critical parameters:

• Filter Type: Continuous Low Pass
• Cutoff Frequency: 25kHz
• Filter Order: 2nd Order
• Number of Filters: 2
• Supply Voltage Range: 4.74V ~ 16V, ±2.37V ~ 8V
• Package Type: 24-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount

Only parts meeting all of these specifications are considered direct equivalents. The MAX271CWG+ serves as both the primary part and its own direct substitute, as no alternative manufacturer parts with identical electrical and mechanical characteristics have been provided in the reference data.

Parameter Comparison

Engineering Selection Recommendations

The MAX271CWG+ is an active product with full regulatory compliance. It carries ROHS3 certification and is REACH unaffected, making it suitable for applications in regulated industries. The device features MSL Level 1 moisture sensitivity, indicating unlimited shelf life under standard storage conditions. Selection of this part is supported by its active production status and confirmed inventory availability of 923 units in new original condition.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the MAX271CWG+?

A: A valid substitute must match all critical parameters: 2nd order continuous low pass filter topology, 25kHz cutoff frequency, dual filter configuration, 4.74V ~ 16V and ±2.37V ~ 8V supply voltage range, and 24-SOIC surface mount package.

Q: Can the MAX271CWG+ be replaced with a different package type?

A: No. The 24-SOIC (0.295", 7.50mm Width) package is a critical mechanical specification. Different package types are not interchangeable without circuit board redesign.

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

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

Q: Are there compliance considerations for substitute selection?

A: Yes. Any substitute must maintain ROHS3 compliance and REACH unaffected status to ensure regulatory compatibility in target applications.

Q: How does the dual filter configuration affect substitution?

A: The MAX271CWG+ contains two independent 2nd order low pass filters. Substitutes must provide exactly two filter channels to maintain circuit functionality.
