MAX271CWG Equivalent & Substitute Parts

Part Overview

The MAX271CWG is a continuous low pass filter IC manufactured by Analog Devices Inc./Maxim Integrated. It implements a 2nd order low pass filter with a 25kHz cutoff frequency in a 24-SOIC surface mount package. The device operates from dual supply voltages of ±2.37V to ±8V or single supply of 4.74V to 16V.

The MAX271CWG is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for applications requiring this filter specification.

Key Parameters

Substitute Part Grouping Explanation

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

• Filter Topology: Continuous low pass configuration
• Filter Order: 2nd order
• Cutoff Frequency: 25kHz
• Number of Filter Channels: 2
• Supply Voltage Range: 4.74V ~ 16V (single supply) or ±2.37V ~ 8V (dual supply)
• Package Type: 24-SOIC form factor
• Mounting Technology: Surface mount

The MAX271CWG+ qualifies as a direct substitute because it maintains identical electrical specifications and package configuration. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MAX271CWG+ is the direct substitute for the MAX271CWG. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and provide identical electrical and mechanical specifications.

The MAX271CWG+ is classified as active product status, ensuring ongoing availability and manufacturer support. The MAX271CWG+ achieves ROHS3 compliance, whereas the original MAX271CWG is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulatory requirements or customer specifications mandating compliant components.

Both parts maintain MSL Level 1 moisture sensitivity classification, indicating unlimited shelf life under standard storage conditions.

Frequently Asked Questions (FAQ)

Q: Can MAX271CWG+ be used as a direct replacement for MAX271CWG?

A: Yes. The MAX271CWG+ provides identical electrical performance and package configuration. Both devices implement a 2nd order continuous low pass filter with 25kHz cutoff frequency, dual filter channels, and 24-SOIC surface mount packaging. Electrical specifications including supply voltage range (4.74V ~ 16V or ±2.37V ~ 8V) are equivalent.

Q: What is the primary difference between MAX271CWG and MAX271CWG+?

A: The MAX271CWG+ is active product status with ROHS3 compliance, while the MAX271CWG is obsolete and RoHS non-compliant. The MAX271CWG+ is supplied in tube packaging.

Q: Are there any package or pinout differences?

A: No. Both parts use the 24-SOIC package with 0.295" width (7.50mm). Pinout and mechanical dimensions are identical.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical function. Both parts deliver identical filter performance.

Q: What is the moisture sensitivity level for these parts?

A: Both MAX271CWG and MAX271CWG+ are classified as MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions and unlimited shelf life under standard storage conditions.
