MAX4519CPD+ Equivalent & Substitute Parts Reference

Part Overview

The MAX4519CPD+ is a 2-circuit IC switch with DPST-NO (Double Pole Single Throw - Normally Open) configuration manufactured by Analog Devices Inc./Maxim Integrated. This component functions as a 2:1 multiplexer/demultiplexer with 100Ohm on-state resistance, designed for analog signal switching applications requiring low on-resistance and fast switching performance. The part is currently in active production status with 1062 units available in new original stock. Alternative equivalent parts are identified to support supply chain continuity and design flexibility when the primary part becomes unavailable or when procurement requirements necessitate sourcing from alternative channels.

Engineering Selection Recommendations

The MAX4519CPD+ is an active production component with full ROHS3 compliance and MSL Level 1 rating, indicating unrestricted moisture sensitivity handling. Selection of equivalent parts should prioritize components maintaining identical compliance certifications and active product status. The direct equivalent MAX4519CPD+ maintains full parameter parity across all electrical and mechanical specifications, ensuring drop-in compatibility for through-hole PCB applications. Component selection should be based on availability, lead time requirements, and procurement channel preferences, as all parameters remain constant across equivalent designations.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the MAX4519CPD+? A: A valid substitute must match all critical parameters including DPST-NO switch configuration, 2:1 multiplexer ratio, 100Ohm on-state resistance, 4Ohm maximum channel matching, supply voltage ranges (2.7V ~ 15V single or ±2.7V ~ 8V dual), 150ns switching time, 5pC charge injection, specified channel capacitance values, 100pA leakage current, -92dB crosstalk performance, 0°C ~ 70°C operating temperature, and 14-DIP through-hole package format.

Q: Can the MAX4519CPD+ be replaced with a surface-mount equivalent? A: No. The MAX4519CPD+ is specified for through-hole mounting in a 14-DIP package. Surface-mount alternatives would require different package specifications and are not considered direct equivalents for this application.

Q: Are there any compliance considerations when selecting a substitute? A: Yes. Any substitute must maintain ROHS3 compliance status and MSL Level 1 rating to ensure compatibility with standard PCB assembly processes and environmental regulations.

Q: What is the significance of the 4Ohm channel-to-channel matching specification? A: The ΔRon specification of 4Ohm maximum ensures that the on-state resistance between the two circuits remains closely matched, which is critical for applications requiring balanced signal switching and minimal crosstalk between channels.

Q: Does the MAX4519CPD+ support both single and dual supply operation? A: Yes. The component supports single supply operation from 2.7V to 15V or dual supply operation from ±2.7V to ±8V, providing flexibility for various circuit topologies.
