MAX7401CSA Equivalent & Substitute Parts

Part Overview

The MAX7401CSA is a Bessel, Low Pass Switched Capacitor Filter IC manufactured by Analog Devices Inc./Maxim Integrated. This 8th order filter operates at a 5kHz cutoff frequency and is housed in an 8-SOIC surface mount package. The part is currently classified as obsolete, making identification of suitable substitutes essential for ongoing design support and component procurement. The MAX7401CSA+ serves as the direct active equivalent, offering identical electrical performance with updated compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX7401CSA is determined by strict equivalence across the following critical parameters:

• Filter topology and order (Bessel, Low Pass Switched Capacitor, 8th order)
• Cutoff frequency (5kHz)
• Supply voltage range (4.5V ~ 5.5V)
• Package type and physical dimensions (8-SOIC, 0.154" width)
• Pin configuration and electrical interface

The MAX7401CSA+ meets all substitution criteria. Both parts share identical electrical specifications, filter characteristics, and package geometry. The primary distinction is product status and regulatory compliance, not functional performance.

Parameter Comparison

Engineering Selection Recommendations

The MAX7401CSA+ is the direct substitute for the obsolete MAX7401CSA. Both parts are electrically and mechanically identical, with pin-for-pin compatibility and identical filter performance characteristics. The MAX7401CSA+ is the preferred selection for new designs and ongoing production due to its active product status and ROHS3 compliance. For legacy systems currently using the MAX7401CSA, direct replacement with the MAX7401CSA+ requires no circuit modifications or re-qualification. The transition from RoHS non-compliant to ROHS3 compliant status reflects current manufacturing standards without altering electrical performance or package specifications.

Frequently Asked Questions (FAQ)
