MAX4519EEE+ Equivalent & Substitute Parts

Part Overview

The MAX4519EEE+ is a 2-circuit IC switch with DPST-NO configuration and 100Ohm on-state resistance, manufactured by Analog Devices Inc./Maxim Integrated. This interface component operates across single supply (2V ~ 15V) and dual supply (±2.7V ~ 8V) ranges, making it suitable for signal routing and multiplexing applications requiring low on-state resistance and fast switching performance. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Identifying equivalent and substitute parts is necessary when addressing supply chain constraints, regional availability limitations, or design optimization requirements while maintaining electrical and mechanical compatibility with the original specification.

Substitute Part Grouping Explanation

Substitution eligibility for the MAX4519EEE+ is determined by strict equivalence across the following critical parameters:

Switch circuit topology: DPST - NO configuration
Channel count and multiplexer ratio: 2 circuits with 2:1 multiplexing
On-state resistance specification: 100Ohm maximum
Channel-to-channel matching tolerance: 4Ohm maximum
Supply voltage ranges: Single supply 2V ~ 15V and dual supply ±2.7V ~ 8V
Switching performance: Maximum 150ns for both Ton and Toff
Package form factor: 16-SSOP surface mount with 0.154" width (3.90mm)
Regulatory compliance: ROHS3 compliance and MSL 1 rating

Only parts meeting all these specifications qualify as direct substitutes. The MAX4519EEE+ itself represents the primary equivalent part number for this application.

Engineering Selection Recommendations

The MAX4519EEE+ maintains active production status with full ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), indicating stable long-term availability and suitability for standard manufacturing environments without special handling requirements.

Component selection should prioritize parts with identical electrical specifications across all parameters listed in the Key Parameters table. The 16-SSOP surface mount package with 0.154" width (3.90mm) is a critical mechanical constraint for PCB layout compatibility. Verify that substitute candidates maintain the same package footprint and pin configuration before design integration.

Compliance certifications including ROHS3 status and REACH unaffected designation should be confirmed for substitute parts to ensure regulatory alignment with the original specification.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the MAX4519EEE+?

A: A valid substitute must match all electrical parameters including DPST-NO switch configuration, 2:1 multiplexer ratio, 100Ohm on-state resistance, 4Ohm maximum channel-to-channel matching, supply voltage ranges (2V ~ 15V single, ±2.7V ~ 8V dual), 150ns maximum switching time, and the 16-SSOP surface mount package form factor.

Q: Are there alternative package options for this switch circuit?

A: The MAX4519EEE+ is specified in 16-SSOP (0.154", 3.90mm Width) surface mount packaging. Substitute parts must use the identical package to ensure PCB compatibility and pin-to-pin equivalence.

Q: What is the significance of the 4Ohm channel-to-channel matching specification?

A: Channel-to-channel matching (ΔRon) of 4Ohm maximum ensures consistent on-state resistance between the two circuits within the device. This parameter is critical for applications requiring balanced signal routing and is a mandatory matching criterion for substitutes.

Q: Does the MAX4519EEE+ support both single and dual supply operation?

A: Yes. The device operates across single supply range 2V ~ 15V (V+) and dual supply range ±2.7V ~ 8V (V±). Substitute parts must support both supply configurations to maintain design flexibility.

Q: What is the moisture sensitivity level (MSL) rating and why does it matter?

A: The MAX4519EEE+ carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. This allows standard manufacturing processes without special dry-pack handling or bake-out procedures. Substitute parts should maintain this MSL rating for manufacturing compatibility.

Q: How does the -92dB crosstalk specification impact circuit performance?

A: Crosstalk of -92dB @ 100kHz indicates the level of signal coupling between channels. This specification is relevant for high-frequency applications and should be matched in substitute parts to maintain signal integrity characteristics.
