MAX4618CSE Equivalent & Substitute Parts

Part Overview

The MAX4618CSE is a dual 4:1 analog switch IC manufactured by Analog Devices Inc./Maxim Integrated, designed for signal routing and multiplexing applications. This component features SP4T (Single Pole, 4-Throw) switching architecture with 10Ohm on-state resistance per circuit, operating across a 2V to 5.5V single supply voltage range. The device is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution eligibility for the MAX4618CSE is determined by strict equivalence across the following critical parameters:

Switch topology (SP4T, 4:1 multiplexer configuration with 2 circuits) must remain identical. Electrical performance specifications including on-state resistance (10Ohm maximum), channel matching (200mOhm), supply voltage range (2V to 5.5V), switching times (15ns/10ns), charge injection (3pC), capacitance values (5pF/15pF), leakage current (1nA), and crosstalk performance (-96dB @ 100kHz) must be maintained. Package and mounting specifications (16-SOIC surface mount) must be compatible with existing PCB layouts.

The MAX4618CSE+ qualifies as a direct substitute based on identical electrical and mechanical parameters across all specified criteria.

Engineering Selection Recommendations

The MAX4618CSE+ is the direct functional equivalent for MAX4618CSE applications. Both parts maintain identical electrical specifications and package configurations, ensuring pin-for-pin compatibility and circuit-level interchangeability.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The MAX4618CSE is classified as obsolete, while the MAX4618CSE+ maintains active product status. Additionally, the MAX4618CSE+ achieves ROHS3 compliance, whereas the original MAX4618CSE is RoHS non-compliant. Both parts carry identical REACH and ECCN classifications.

For new designs and ongoing system support where component availability is a consideration, the MAX4618CSE+ is the appropriate selection due to its active status and modern compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can MAX4618CSE+ be used as a direct replacement for MAX4618CSE in existing designs?

A: Yes. The MAX4618CSE+ is electrically and mechanically identical to the MAX4618CSE across all specified parameters. Pin configuration, package dimensions (16-SOIC), and electrical performance characteristics are equivalent, enabling direct substitution without circuit modification.

Q: What is the significance of the product status difference between these parts?

A: The MAX4618CSE is classified as obsolete, indicating discontinued manufacturing and limited availability. The MAX4618CSE+ maintains active product status, ensuring ongoing supply and manufacturing support from Analog Devices Inc./Maxim Integrated.

Q: Are there compliance differences between MAX4618CSE and MAX4618CSE+?

A: The MAX4618CSE+ is ROHS3 compliant, while the MAX4618CSE is RoHS non-compliant. Both parts are REACH Unaffected and carry identical ECCN classification (EAR99). For applications requiring RoHS compliance, the MAX4618CSE+ is the appropriate selection.

Q: Do packaging options differ between these parts?

A: Both parts use identical 16-SOIC surface mount packaging (0.154" width, 3.90mm). The primary packaging difference is that MAX4618CSE+ is supplied in Tube packaging, while the original MAX4618CSE packaging specification is not detailed. This does not affect electrical or mechanical compatibility.

Q: What electrical parameters determine substitution eligibility for this device category?

A: Substitution requires equivalence in switch topology (SP4T, 4:1 configuration), on-state resistance (10Ohm), channel matching (200mOhm), supply voltage range (2V to 5.5V), switching times (15ns/10ns), charge injection (3pC), capacitance specifications (5pF/15pF), leakage current (1nA), and crosstalk performance (-96dB @ 100kHz).
