Substitute Part Grouping Explanation

Substitution for the PS393ESEE is determined by the following critical parameters: switch circuit type (SPST NO/NC), number of circuits (4), multiplexer configuration (1:1), package type (16-SOIC), and electrical performance envelope including on-state resistance, supply voltage range, and operating temperature range.

The substitute parts are grouped into three functional categories based on on-state resistance specifications:

Category 1: Lower On-State Resistance (35Ohm) — MAX393 series parts (MAX393CSE+, MAX393CSE+T, MAX393ESE+, MAX393ESE+T) provide improved performance with reduced on-state resistance while maintaining the same circuit topology and package footprint. These parts are active products with enhanced electrical characteristics.

Category 2: Lowest On-State Resistance (25Ohm) — MAX4713 series parts (MAX4713ESE+, MAX4713ESE+T) offer the lowest on-state resistance with tighter channel matching and faster switching times, suitable for applications requiring minimal signal attenuation.

Category 3: Higher Supply Voltage Range (160Ohm) — MAX4513 series parts (MAX4513ESE+, MAX4513ESE+T) are designed for higher supply voltage applications (9V to 36V) with different electrical characteristics and are not direct functional equivalents for standard 3V to 15V single-supply designs.

Engineering Selection Recommendations

For Direct Replacement (Preferred): MAX393ESE+ or MAX393ESE+T are the primary substitutes. Both maintain the full operating temperature range (-40°C to 85°C) matching the PS393ESEE, are active products with ongoing manufacturer support, and provide superior electrical performance with 35Ohm on-state resistance and improved channel matching. The ESE+ variant in tube packaging and ESE+T variant in tape & reel offer identical electrical specifications; packaging selection depends on procurement and assembly requirements.

For Enhanced Performance: MAX4713ESE+ or MAX4713ESE+T deliver the lowest on-state resistance (25Ohm) with tighter channel matching (200mOhm) and faster switching times. These parts are suitable when signal attenuation must be minimized. Operating temperature range remains -40°C to 85°C. Note that supply voltage range is reduced to 2.7V to 11V single supply and ±2.7V to ±5.5V dual supply; applications requiring the full 15V single supply capability of the PS393ESEE are not compatible.

Not Recommended for Direct Substitution: MAX4513ESE+ and MAX4513ESE+T are designed for higher supply voltage applications (9V to 36V) with significantly different electrical characteristics including 160Ohm on-state resistance and slower switching times. These parts are not functionally equivalent for standard 3V to 15V designs.

All recommended substitutes are ROHS3 compliant with MSL 1 rating, matching the environmental and regulatory status of the PS393ESEE.

Frequently Asked Questions (FAQ)

Q: Can MAX393ESE+ directly replace PS393ESEE in existing designs?

A: MAX393ESE+ is electrically compatible for applications operating within the overlapping parameter ranges. Both parts feature 4-circuit SPST NO/NC configuration, identical supply voltage ranges (3V to 15V single, ±3V to ±8V dual), matching operating temperature range (-40°C to 85°C), and 16-SOIC package type. The MAX393ESE+ provides superior performance with lower on-state resistance (35Ohm vs 45Ohm) and improved channel matching. Physical package dimensions differ slightly (0.154" vs 0.295" width), but both are standard 16-SOIC footprints compatible with typical PCB layouts.

Q: What is the difference between MAX393ESE+ and MAX393CSE+?

A: Both parts are electrically identical with 35Ohm on-state resistance and identical electrical specifications. The primary difference is operating temperature range: MAX393ESE+ operates -40°C to 85°C (matching PS393ESEE), while MAX393CSE+ operates 0°C to 70°C. For applications requiring full industrial temperature range, MAX393ESE+ is the appropriate choice. Packaging differs: MAX393ESE+ is supplied in tube, MAX393CSE+ in tube as well, with corresponding tape & reel variants (ESE+T and CSE+T).

Q: Why is MAX4713ESE+ not recommended as a direct replacement?

A: While MAX4713ESE+ offers superior electrical performance with 25Ohm on-state resistance and faster switching, it has a reduced supply voltage range (2.7V to 11V single supply, ±2.7V to ±5.5V dual supply). Applications requiring the full 15V single supply capability of the PS393ESEE cannot use MAX4713ESE+. Additionally, charge injection is significantly higher (25pC vs 3pC), which may affect precision analog switching performance in sensitive applications.

Q: Are there package compatibility concerns when substituting?

A: All substitute parts use 16-SOIC package type compatible with standard surface-mount assembly processes. Physical dimensions vary slightly: PS393ESEE is 0.295" width while MAX393 and MAX4713 series are 0.154" width. Both dimensions are within standard 16-SOIC specifications and compatible with typical PCB footprints. Verify PCB layout accommodates the specific package width if tight spacing is present.

Q: What packaging options are available for substitute parts?

A: MAX393 and MAX4713 series are available in two packaging formats: tube (standard packaging for lower volumes) and tape & reel (for automated assembly and higher volumes). Part numbers ending in "+" indicate tube packaging; part numbers ending in "+T" indicate tape & reel. Select based on procurement volume and assembly process requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All recommended substitute parts (MAX393 and MAX4713 series) are ROHS3 compliant with MSL 1 rating, matching the environmental compliance status of the PS393ESEE. All parts are REACH unaffected and classified as EAR99 for export control purposes.
