MAX3969ETP Equivalent & Substitute Parts

Part Overview

The MAX3969ETP is a Limiting Amplifier IC designed for optical network applications, manufactured by Analog Devices Inc./Maxim Integrated. This component operates as a linear amplifier in a 20-TQFN (4x4) surface mount package with an exposed pad. The device is classified as obsolete, which necessitates identification of active equivalent parts to maintain supply chain continuity for new designs and production requirements. The MAX3969ETP+ serves as the direct active substitute, offering identical electrical and mechanical specifications with current manufacturing status.

Substitute Part Grouping Explanation

Substitution of the MAX3969ETP is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Component type: Limiting Amplifier
• Product category: Linear, Amplifiers
• Application domain: Optical Networks

Mechanical Equivalence Criteria:

• Package type: 20-WFQFN Exposed Pad
• Supplier device package: 20-TQFN (4x4)
• Mounting type: Surface Mount

Compliance Equivalence Criteria:

• RoHS status: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)
• ECCN classification: EAR99
• HTSUS code: 8542.33.0001

The MAX3969ETP+ is a direct substitute because it maintains identical specifications across all electrical, mechanical, and compliance parameters. The primary distinction is product status: the MAX3969ETP is obsolete, while the MAX3969ETP+ is active. The packaging designation difference (Tube for MAX3969ETP+) represents a supply format variation only and does not affect functional or physical compatibility.
