MAX4619ESE Equivalent & Substitute Parts
Part Overview
The MAX4619ESE is a 3-circuit SPDT (Single Pole Double Throw) analog switch IC manufactured by Analog Devices Inc./Maxim Integrated. This component functions as a 2:1 multiplexer/demultiplexer with 10Ohm on-state resistance, designed for signal routing and switching applications in mixed-signal systems. The MAX4619ESE is classified as obsolete, making identification of compatible substitute parts essential for ongoing production support and design continuity.

Substitute Part Grouping Explanation
Substitution of the MAX4619ESE is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must satisfy the following criteria:
- Identical switch circuit topology (SPDT)
- Identical multiplexer configuration (2:1)
- Identical number of circuits (3)
- Matching on-state resistance specification (10Ohm maximum)
- Matching channel-to-channel resistance matching (200mOhm)
- Compatible supply voltage range (2V ~ 5.5V minimum)
- Equivalent or superior switching performance (Ton/Toff specifications)
- Identical or superior charge injection and capacitance characteristics
- Identical package and pinout (16-SOIC)
- Surface mount compatibility
The MAX4619ESE+ meets all substitution criteria as a direct equivalent with identical electrical specifications and package configuration.

Engineering Selection Recommendations
The MAX4619ESE+ is the direct substitute for the obsolete MAX4619ESE. Both parts share identical electrical specifications, switching characteristics, and 16-SOIC package configuration, ensuring pin-for-pin compatibility and functional equivalence in existing circuit designs.
The primary distinction between the two parts is product status and regulatory compliance. The MAX4619ESE is classified as obsolete with RoHS non-compliant status, while the MAX4619ESE+ is an active product with ROHS3 compliance. For new designs or production continuity, the MAX4619ESE+ is the appropriate selection. Both parts maintain identical moisture sensitivity levels and REACH status.
Frequently Asked Questions (FAQ)
Q: Can MAX4619ESE+ be used as a direct replacement for MAX4619ESE in existing designs?
A: Yes. The MAX4619ESE+ is electrically and mechanically identical to the MAX4619ESE. All electrical parameters, switching characteristics, and package specifications are equivalent, enabling direct substitution without circuit modification.
Q: What is the difference between MAX4619ESE and MAX4619ESE+?
A: The parts are functionally identical. The primary differences are product status (obsolete vs. active) and RoHS compliance (non-compliant vs. ROHS3 compliant). The MAX4619ESE+ is the current production equivalent.
Q: Are the packages identical?
A: Yes. Both parts use the 16-SOIC package with 0.154" width (3.90mm). Pinout and footprint are identical, supporting direct PCB compatibility.
