MAX280CWE Equivalent & Substitute Parts

Part Overview

The MAX280CWE is a Butterworth, 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 part is classified as obsolete, making identification of suitable substitutes essential for ongoing system support and new design implementations. The primary driver for substitution is the discontinued product status combined with the availability of functionally equivalent active alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MAX280CWE is determined by strict equivalence across the following critical parameters:

• Filter topology and order (Butterworth, Low Pass Switched Capacitor, 5th order)
• Cutoff frequency (20kHz)
• Supply voltage range (4.75V ~ 16V, ±2.375V ~ 8V)
• Package type (16-SOIC)
• Pin-for-pin compatibility and functional behavior

The MAX280CWE+ qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MAX280CWE+ is the direct functional equivalent of the MAX280CWE. Both parts share identical electrical characteristics, filter specifications, and package configuration. The MAX280CWE+ is the preferred selection for new designs and ongoing production due to its active product status and ROHS3 compliance certification. The original MAX280CWE, classified as obsolete, should be replaced with the MAX280CWE+ in applications where component availability and regulatory compliance are considerations. Both parts maintain REACH Unaffected status and identical export classification (EAR99).

Frequently Asked Questions (FAQ)

Q: Can the MAX280CWE+ be used as a direct replacement for the MAX280CWE?

A: Yes. The MAX280CWE+ is electrically and mechanically identical to the MAX280CWE. Both parts feature the same Butterworth 5th order low pass filter topology, 20kHz cutoff frequency, supply voltage range, and 16-SOIC package configuration. Pin-for-pin compatibility is maintained.

Q: What is the primary difference between MAX280CWE and MAX280CWE+?

A: The MAX280CWE+ is the active production variant with ROHS3 compliance certification. The original MAX280CWE is classified as obsolete. Both parts are functionally equivalent.

Q: Are there packaging differences between these parts?

A: Both parts use the 16-SOIC (0.295", 7.50mm Width) surface mount package. The MAX280CWE+ is supplied in tube packaging, while the original MAX280CWE packaging specification is not detailed. The physical package dimensions and pin configuration are identical.

Q: What supply voltage range does the MAX280CWE support?

A: The MAX280CWE operates with a supply voltage range of 4.75V ~ 16V for single supply operation, or ±2.375V ~ 8V for dual supply operation.

Q: Is the MAX280CWE RoHS compliant?

A: The original MAX280CWE is RoHS non-compliant. The MAX280CWE+ is ROHS3 compliant and is the recommended choice for applications requiring RoHS certification.
