PS392CSEE Equivalent & Substitute Parts

Part Overview

The PS392CSEE is a 4-circuit SPST-NO IC switch manufactured by Diodes Incorporated, featuring 45Ohm on-state resistance in a 16-SOIC package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The part operates across 3V to 15V single supply or ±3V to ±8V dual supply configurations, with switching times of 130ns (Ton) and 75ns (Toff). Alternative parts must maintain functional compatibility within the SPST-NO 4-circuit switch category while accommodating variations in on-state resistance, supply voltage ranges, and operating temperature specifications.

Engineering Selection Recommendations

Primary Substitutes (Closest Electrical Match):

The MAX392 series (MAX392CSE+, MAX392CSE+T, MAX392ESE+, MAX392ESE+T) provides the closest functional equivalence to the PS392CSEE. These parts maintain identical supply voltage ranges (3V ~ 15V single, ±3V ~ 8V dual), matching switch timing (130ns, 75ns), and equivalent on-state resistance (35Ohm vs. 45Ohm). All MAX392 variants are ROHS3 compliant with MSL 1 rating. The primary difference is package width (3.90mm vs. 7.50mm), requiring PCB layout verification. The ESE+ variants extend operating temperature to -40°C to 85°C, providing enhanced thermal range for applications requiring extended temperature operation.

Secondary Substitutes (Moderate Parameter Variation):

The MAX4712ESE+ offers lower on-state resistance (25Ohm) with comparable switching performance (125ns, 80ns) but operates at reduced supply voltages (2.7V ~ 11V single, ±2.7V ~ 5.5V dual). This part is suitable for low-voltage applications within the specified range. The ALD4202MSCL provides higher on-state resistance (135Ohm) with extended switching times (240ns, 130ns) and operates within 3V ~ 12V single supply range, suitable for applications tolerating slower switching and higher resistance.

Extended Range Substitutes (Specialized Applications):

The MAX4512 series (MAX4512CSE+, MAX4512ESE+, MAX4512ESE+T) operates at higher supply voltages (9V ~ 36V single, ±4.5V ~ 18V dual) with significantly higher on-state resistance (160Ohm) and slower switching times (500ns, 400ns). These parts are applicable only to high-voltage, low-speed switching applications. The DG455EY-T1-E3 from Vishay Siliconix features the lowest on-state resistance (5.3Ohm) with extended operating temperature (-40°C ~ 125°C) but requires 12V ~ 36V supply voltage, limiting applicability to high-voltage designs.

Compliance and Availability:

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols. Active product status across all recommended substitutes ensures long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can MAX392CSE+ directly replace PS392CSEE without PCB modification?

A: Electrical substitution is valid; however, package width differs (3.90mm vs. 7.50mm). PCB footprint verification is required. Both parts use 16-SOIC surface mount configuration with identical pin count and function, but physical dimensions necessitate layout review.

Q: What is the primary reason PS392CSEE is obsolete?

A: The PS392CSEE is classified as obsolete by the manufacturer. Active alternatives from Analog Devices (MAX392 series) and other manufacturers provide equivalent or superior performance with ongoing production support.

Q: Which substitute offers the closest performance match?

A: The MAX392 series (CSE+ and ESE+ variants) provides the closest match with identical supply voltage ranges, switching times, and comparable on-state resistance (35Ohm vs. 45Ohm). The ESE+ variants additionally support extended operating temperature (-40°C to 85°C).

Q: Are all substitutes compatible with 3V to 15V single supply operation?

A: No. The MAX4712ESE+ operates at 2.7V ~ 11V, the ALD4202MSCL at 3V ~ 12V, and the MAX4512 series at 9V ~ 36V. Only the MAX392 series and DG455EY-T1-E3 support the full 3V ~ 15V range. Application supply voltage must be verified against substitute specifications.

Q: What is the significance of on-state resistance variation among substitutes?

A: On-state resistance directly affects signal attenuation and power dissipation. Lower resistance (5.3Ohm DG455) reduces signal loss but requires higher supply voltage. Higher resistance (160Ohm MAX4512) increases attenuation but supports wider voltage ranges. Selection depends on application signal integrity and power budget requirements.

Q: Do all substitutes maintain the same package footprint?

A: No. The PS392CSEE uses 16-SOIC with 7.50mm width. Most substitutes use 16-SOIC with 3.90mm width. Physical package dimensions differ despite identical pin count. PCB layout compatibility must be confirmed before design implementation.

Q: Which substitute supports the widest operating temperature range?

A: The DG455EY-T1-E3 supports -40°C to 125°C, the widest range among all listed parts. The MAX392ESE+, MAX392ESE+T, MAX4712ESE+, MAX4512ESE+, and MAX4512ESE+T all support -40°C to 85°C. The PS392CSEE operates only to 70°C.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and environmental regulations.

Q: What packaging options are available for the MAX392 series?

A: The MAX392 series is available in both Tube (CSE+, ESE+) and Tape & Reel (CSE+T, ESE+T) packaging. Tape & Reel variants are suitable for automated assembly processes, while Tube packaging is appropriate for manual or lower-volume applications.
