PS393CSEE Equivalent & Substitute Parts
Part Overview
The PS393CSEE is a 4-circuit IC switch manufactured by Diodes Incorporated, featuring SPST NO/NC configuration with 45Ohm on-state resistance in 16-SOIC packaging. This part is classified as obsolete, making equivalent substitutes necessary for ongoing design support and procurement. The PS393CSEE 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.

Substitute Part Grouping Explanation
Substitution eligibility for the PS393CSEE is determined by the following critical parameters:
Primary Substitution Criteria:
- Switch circuit configuration: SPST - NO/NC
- Number of circuits: 4
- Multiplexer/Demultiplexer circuit: 1:1
- Package type: 16-SOIC surface mount
- Supply voltage compatibility: Overlapping single or dual supply ranges
- Operating temperature range: Must encompass or match the original 0°C ~ 70°C specification
Secondary Compatibility Factors:
- On-state resistance: Lower values provide improved performance; higher values require application verification
- Switch timing characteristics: Ton/Toff parameters must be suitable for signal bandwidth requirements
- Leakage current and crosstalk: Lower values indicate superior performance
- Charge injection: Lower values reduce signal distortion
The substitute parts are grouped into three functional categories based on on-state resistance performance: low-resistance variants (25Ohm), mid-range variants (35Ohm), and high-resistance variants (160Ohm). Each category maintains the core 4-circuit SPST configuration but differs in electrical performance characteristics and supply voltage requirements.

Engineering Selection Recommendations
MAX393 Series (MAX393CSE+, MAX393CSE+T, MAX393ESE+, MAX393ESE+T)
The MAX393 series represents the primary substitute category for PS393CSEE applications requiring 3V to 15V single supply or ±3V to ±8V dual supply operation. All MAX393 variants maintain identical electrical performance with 35Ohm on-state resistance, 130ns/75ns switching times, and improved channel matching (300mOhm vs. 500mOhm). These parts are active products from Analog Devices Inc./Maxim Integrated with full ROHS3 compliance and MSL 1 rating.
Selection between MAX393 packaging variants depends on procurement requirements: MAX393CSE+ and MAX393ESE+ are supplied in tube packaging, while MAX393CSE+T and MAX393ESE+T are supplied in tape and reel format. The MAX393ESE+ and MAX393ESE+T variants extend operating temperature to -40°C to 85°C, providing broader environmental coverage compared to the 0°C to 70°C range of MAX393CSE+ and MAX393CSE+T.
MAX4713 Series (MAX4713ESE+, MAX4713ESE+T)
The MAX4713 series provides superior low-resistance performance with 25Ohm on-state resistance and 200mOhm channel matching. These parts operate across 2.7V to 11V single supply or ±2.7V to ±5.5V dual supply ranges, making them suitable for lower-voltage applications. Switch timing remains comparable (125ns/80ns) with extended -40°C to 85°C operating temperature. Higher charge injection (25pC vs. 3pC) requires application-level assessment for signal integrity in sensitive analog circuits.
MAX4513 Series (MAX4513ESE+, MAX4513ESE+T)
The MAX4513 series is suitable only for applications requiring higher supply voltages (9V to 36V single supply or ±4.5V to ±18V dual supply). The 160Ohm on-state resistance and slower switching times (500ns/400ns) make this series incompatible with the PS393CSEE's performance envelope for standard 3V to 15V applications. This series is appropriate only when supply voltage requirements exceed the MAX393 and MAX4713 operating ranges.
Compliance and Certification
All substitute parts maintain ROHS3 compliance and MSL 1 (unlimited) moisture sensitivity rating, matching the PS393CSEE specifications. All parts are manufactured by Analog Devices Inc./Maxim Integrated and carry active product status, ensuring long-term availability and manufacturing support.
Frequently Asked Questions (FAQ)
Q: Can MAX393 variants directly replace PS393CSEE in existing designs?
A: MAX393 variants are electrically compatible for applications operating within 3V to 15V single supply or ±3V to ±8V dual supply ranges. Physical package dimensions differ (MAX393 uses 0.154" width vs. PS393CSEE 0.295" width), requiring PCB layout verification. All MAX393 variants maintain the 4-circuit SPST NO/NC configuration and 16-SOIC pinout compatibility.
Q: What is the difference between tube and tape & reel packaging?
A: Tube packaging (MAX393CSE+, MAX393ESE+, MAX4713ESE+, MAX4513ESE+) is suitable for lower-volume applications and manual assembly. Tape & reel packaging (MAX393CSE+T, MAX393ESE+T, MAX4713ESE+T, MAX4513ESE+T) is designed for automated pick-and-place assembly and higher-volume production. Electrical specifications are identical between packaging variants of the same base part number.
Q: Why do MAX393ESE+ and MAX393ESE+T have extended operating temperature?
A: MAX393ESE+ and MAX393ESE+T are rated for -40°C to 85°C operation, compared to 0°C to 70°C for MAX393CSE+ and MAX393CSE+T. Extended temperature rating provides design margin for applications with broader environmental requirements. Electrical performance remains identical across all MAX393 variants.
Q: Is MAX4713 suitable as a PS393CSEE replacement?
A: MAX4713 is electrically compatible for applications where lower on-state resistance (25Ohm) and improved channel matching (200mOhm) provide performance benefits. However, MAX4713 operates across 2.7V to 11V single supply or ±2.7V to ±5.5V dual supply, which is narrower than PS393CSEE's 3V to 15V range. Applications requiring full 15V operation must use MAX393 series. Higher charge injection (25pC) requires signal integrity assessment.
Q: When should MAX4513 be considered?
A: MAX4513 is appropriate only for applications requiring supply voltages exceeding 11V single supply or ±5.5V dual supply. The 160Ohm on-state resistance and 500ns/400ns switching times make MAX4513 unsuitable for standard 3V to 15V applications. MAX4513 is not a direct replacement for PS393CSEE in conventional low-voltage analog switching applications.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All MAX393, MAX4713, and MAX4513 variants maintain ROHS3 compliance and MSL 1 (unlimited) moisture sensitivity rating, matching PS393CSEE environmental specifications.
Q: What is the impact of different on-state resistance values?
A: Lower on-state resistance reduces signal attenuation and power dissipation. MAX4713 (25Ohm) provides superior performance compared to PS393CSEE (45Ohm) and MAX393 (35Ohm). Higher resistance in MAX4513 (160Ohm) increases signal loss and is suitable only for high-impedance applications or higher supply voltage operation.
Q: How do crosstalk specifications compare?
A: PS393CSEE specifies -90dB crosstalk at 1MHz. MAX393 variants provide -85dB, MAX4713 provides -87dB, and MAX4513 provides -66dB. Lower crosstalk values indicate superior channel isolation. Applications sensitive to cross-channel interference should prioritize MAX393 or MAX4713 series.
