PS393ESE Equivalent & Substitute Parts

Part Overview

The PS393ESE is a 4-circuit IC switch manufactured by Diodes Incorporated, featuring SPST NO/NC configuration with 45Ohm on-state resistance in a 16-SOIC package. This part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. The PS393ESE operates across single supply (3V to 15V) and dual supply (±3V to ±8V) configurations with 100MHz bandwidth and low charge injection characteristics suitable for analog signal switching applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the PS393ESE is determined by the following critical parameters: switch circuit topology (SPST NO/NC), number of circuits (4), package type (16-SOIC), and electrical performance characteristics including on-state resistance, supply voltage ranges, and switching speed.

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

Low Resistance Group (25Ohm - 35Ohm): MAX4713ESE+, MAX4713ESE+T, MAX393ESE+, MAX393ESE+T, MAX393CSE+, MAX393CSE+T. These parts offer improved on-state resistance performance compared to the PS393ESE, with lower channel-to-channel matching and reduced charge injection. They maintain compatible supply voltage ranges and switching characteristics suitable for direct replacement in most applications.

High Resistance Group (160Ohm): MAX4513ESE+, MAX4513ESE+T. These parts feature significantly higher on-state resistance and operate across extended supply voltage ranges (9V to 36V single supply, ±4.5V to ±18V dual supply). These are suitable only for applications where higher on-state resistance is acceptable and higher supply voltages are required.

All substitute parts maintain 16-SOIC packaging, SPST NO/NC switch configuration, and 4-circuit topology. Differences in on-state resistance, supply voltage ranges, and switching speed must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement with Improved Performance: The MAX393ESE+ and MAX393ESE+T series provide the closest functional equivalence to the PS393ESE. These parts maintain identical supply voltage ranges (3V to 15V single, ±3V to ±8V dual), matching switch timing characteristics (130ns, 75ns), and identical operating temperature range (-40°C to 85°C). The MAX393ESE+ variants offer superior on-state resistance (35Ohm versus 45Ohm), lower channel-to-channel matching (300mOhm versus 500mOhm), and reduced charge injection (2pC versus 3pC). All MAX393 variants are ROHS3 compliant and carry active product status, making them suitable for new designs and production continuity.

For Low-Voltage Applications: The MAX4713ESE+ and MAX4713ESE+T series are appropriate for applications operating at lower supply voltages (2.7V to 11V single, ±2.7V to ±5.5V dual). These parts deliver the lowest on-state resistance (25Ohm) and superior channel-to-channel matching (200mOhm). However, the higher charge injection (25pC) must be evaluated against application sensitivity to charge injection effects. Operating temperature range extends to -40°C to 85°C, matching the PS393ESE specification.

For High-Voltage Applications: The MAX4513ESE+ and MAX4513ESE+T series support extended supply voltage ranges (9V to 36V single, ±4.5V to ±18V dual) with significantly higher on-state resistance (160Ohm). These parts are suitable only when application requirements permit higher on-state resistance and extended supply voltage operation is necessary. Switching time is substantially slower (500ns, 400ns) compared to the PS393ESE.

Packaging Consideration: All substitute parts use 16-SOIC packaging with reduced body width (0.154", 3.90mm) compared to the PS393ESE (0.295", 7.50mm). PCB layout modifications may be required to accommodate the narrower package footprint.

Compliance: All substitute parts are ROHS3 compliant and carry active product status, addressing the obsolescence and non-compliance status of the PS393ESE.

Frequently Asked Questions (FAQ)

Q: Can MAX393ESE+ directly replace PS393ESE in existing designs? A: Yes. The MAX393ESE+ maintains identical supply voltage ranges, switch timing, and operating temperature specifications. The improved on-state resistance (35Ohm versus 45Ohm) and lower channel-to-channel matching (300mOhm versus 500mOhm) provide performance enhancement. PCB layout adjustment is required due to package width reduction from 7.50mm to 3.90mm.

Q: What is the difference between MAX393ESE+ and MAX393CSE+? A: Both parts are electrically identical with 35Ohm on-state resistance and 300mOhm channel-to-channel matching. The primary difference is operating temperature range: MAX393ESE+ operates -40°C to 85°C, while MAX393CSE+ operates 0°C to 70°C. For extended temperature applications, MAX393ESE+ is required.

Q: What is the difference between tube and tape & reel packaging? A: Tube packaging (MAX393ESE+, MAX393CSE+) is suitable for manual assembly and lower-volume production. Tape & Reel packaging (MAX393ESE+T, MAX393CSE+T) is designed for automated pick-and-place assembly and higher-volume production. Electrical specifications are identical between packaging variants.

Q: Can MAX4513ESE+ replace PS393ESE? A: MAX4513ESE+ is not a direct replacement. While it maintains 4-circuit SPST NO/NC configuration and 16-SOIC packaging, it operates across different supply voltage ranges (9V to 36V single, ±4.5V to ±18V dual) and features significantly higher on-state resistance (160Ohm). Use only when application requirements specifically demand higher supply voltages and higher on-state resistance is acceptable.

Q: Why is on-state resistance important for substitution? A: On-state resistance directly affects signal attenuation, power dissipation, and circuit performance. Lower on-state resistance reduces signal loss and heat generation. Substitutes with lower on-state resistance (MAX393, MAX4713 series) provide performance improvement. Substitutes with higher on-state resistance (MAX4513 series) are suitable only for applications where higher resistance is acceptable.

Q: Are all substitute parts RoHS compliant? A: Yes. All substitute parts listed are ROHS3 compliant. The PS393ESE is RoHS non-compliant, making substitution necessary for applications requiring RoHS compliance.
