MAX7423EUA-T Equivalent & Substitute Parts

Part Overview

The MAX7423EUA-T is a Bessel, Low Pass Switched Capacitor Filter IC manufactured by Analog Devices Inc./Maxim Integrated. This 5th order filter operates at a 45kHz cutoff frequency and is housed in an 8-uMAX/uSOP package. The device is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and procurement planning. Equivalent parts maintain identical electrical performance and mechanical compatibility while offering improved availability or compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX7423EUA-T is determined by strict equivalence across the following critical parameters:

• Filter topology and order (Bessel, Low Pass Switched Capacitor, 5th order)
• Cutoff frequency (45kHz)
• Supply voltage range (2.7V ~ 3.6V)
• Package type and physical dimensions (8-TSSOP, 8-MSOP, 0.118" width)
• Pin configuration and functional pinout
• Moisture sensitivity classification (MSL 1)

The MAX7423EUA+T qualifies as a direct equivalent based on identical electrical specifications and mechanical compatibility. The primary distinction is packaging format: the substitute is supplied in Tape & Reel (TR) configuration versus the main part's standard packaging, and the substitute maintains active product status with improved RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

The MAX7423EUA+T is the direct equivalent for MAX7423EUA-T applications. Selection between these parts should be based on the following factors:

Product Status: The MAX7423EUA+T maintains active product status, ensuring continued manufacturer support and long-term availability. The MAX7423EUA-T is obsolete and subject to inventory depletion.

Regulatory Compliance: The MAX7423EUA+T is ROHS3 compliant, meeting current environmental and regulatory requirements. The MAX7423EUA-T is RoHS non-compliant and may present procurement restrictions in regulated markets.

Packaging Considerations: Both parts are electrically and mechanically identical. The substitute is supplied in Tape & Reel format, which is standard for high-volume manufacturing and automated assembly. Selection should align with procurement and assembly process requirements.

Electrical Performance: No performance differences exist between the two parts. Both deliver identical filter characteristics, frequency response, and supply voltage specifications.

Frequently Asked Questions (FAQ)

Q: Can MAX7423EUA+T replace MAX7423EUA-T in existing designs?

A: Yes. The MAX7423EUA+T is a direct electrical and mechanical equivalent. No circuit modifications or PCB redesign is required. Both parts are pin-compatible and functionally identical.

Q: What is the difference between the two part numbers?

A: The primary differences are product status, RoHS compliance, and packaging format. The MAX7423EUA+T is active, ROHS3 compliant, and supplied in Tape & Reel configuration. The MAX7423EUA-T is obsolete and RoHS non-compliant. The "+T" suffix indicates Tape & Reel packaging.

Q: Are there any supply voltage or frequency differences?

A: No. Both parts operate at 2.7V ~ 3.6V supply voltage and feature a 45kHz cutoff frequency. All electrical specifications are identical.

Q: Is the package size the same?

A: Yes. Both parts use the 8-TSSOP, 8-MSOP package with 0.118" (3.00mm) width. Physical dimensions and pin spacing are identical, ensuring direct PCB compatibility.

Q: Why is the main part listed as obsolete?

A: The MAX7423EUA-T has reached end-of-life status. Analog Devices Inc./Maxim Integrated continues to support the MAX7423EUA+T as the active equivalent, ensuring ongoing availability and compliance with current standards.

Q: Can I mix both parts in the same production batch?

A: Yes. Both parts are functionally and mechanically equivalent. However, Tape & Reel packaging (MAX7423EUA+T) is recommended for automated assembly processes to optimize handling and reduce component damage.
