PS392EEE Equivalent & Substitute Parts
Part Overview
The PS392EEE is a 4-circuit SPST-NO IC switch manufactured by Diodes Incorporated, designed for signal routing and switching applications in interface circuits. This part operates with single supply voltage (3V to 15V) or dual supply (±3V to ±8V) and features 45Ohm on-state resistance with 100MHz bandwidth capability. The PS392EEE is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements.

Substitute Part Grouping Explanation
Substitution of the PS392EEE is determined by the following critical parameters:
- Switch topology: SPST-NO with 1:1 multiplexer configuration and 4 circuits
- On-state resistance range: 45Ohm baseline, with acceptable substitutes ranging from 1.1Ohm to 25Ohm depending on application requirements
- Supply voltage compatibility: Single supply 3V minimum and dual supply ±3V minimum
- Package compatibility: 16-pin surface mount packages (SSOP, TSSOP variants)
- Operating temperature range: Minimum -40°C to 85°C
- Compliance: ROHS3 compliant, EAR99 classification
Substitute parts are grouped into three categories based on on-state resistance characteristics:
Low Resistance Group (1.1Ohm): ADG1612BRUZ, ADG1612BRUZ-REEL, ADG1612BRUZ-REEL7 — suitable for applications requiring minimal signal attenuation and lower power dissipation.
Mid Resistance Group (5.3Ohm to 10Ohm): DG455EQ-T1-E3, ADG5412BRUZ, ADG5412BRUZ-REEL7 — balanced performance for general-purpose switching with moderate bandwidth requirements.
High Resistance Group (25Ohm): MAX4712CUE+, MAX4712CUE+T, MAX4712EUE+, MAX4712EUE+T — closest electrical match to PS392EEE, suitable for direct replacement in existing designs.

Engineering Selection Recommendations
For Direct Replacement (Highest Compatibility): MAX4712EUE+ and MAX4712EUE+T are the primary substitutes for PS392EEE. Both maintain 25Ohm on-state resistance, matching the original specification within acceptable tolerance. Operating temperature range (-40°C to 85°C) aligns with PS392EEE requirements. Both are ROHS3 compliant and active products with established supply chains. MAX4712EUE+ is supplied in tube packaging, while MAX4712EUE+T is supplied in tape and reel format.
For Lower Resistance Applications: ADG1612BRUZ series (1.1Ohm) offers significantly reduced on-state resistance, suitable for applications where signal attenuation must be minimized. Extended operating temperature to 125°C provides additional margin. Available in multiple packaging options (tube, cut tape, digi-reel). ADG1612BRUZ-REEL7 provides the highest inventory availability (8503 pcs).
For Higher Voltage Applications: ADG5412BRUZ and ADG5412BRUZ-REEL7 support extended supply voltage ranges (9V to 40V single supply, ±9V to ±22V dual supply). 10Ohm on-state resistance and 160MHz bandwidth accommodate high-frequency switching requirements. Extended operating temperature to 125°C.
For Balanced Performance: DG455EQ-T1-E3 provides 5.3Ohm on-state resistance with 118ns turn-on time (faster than PS392EEE). Supports 12V to 36V single supply and ±5V to ±15V dual supply. Lowest charge injection (22pC) among substitutes.
All substitute parts are ROHS3 compliant, EAR99 classified, and carry MSL rating of 1 (unlimited moisture sensitivity).
Frequently Asked Questions (FAQ)
Q: Can MAX4712CUE+ be used as a direct replacement for PS392EEE? A: MAX4712CUE+ is functionally equivalent with 25Ohm on-state resistance matching PS392EEE. However, operating temperature range is 0°C to 70°C, which is narrower than PS392EEE (-40°C to 85°C). Use MAX4712EUE+ for full temperature range compatibility.
Q: What is the primary difference between ADG1612BRUZ and ADG5412BRUZ? A: ADG1612BRUZ operates at 3.3V to 16V single supply with 1.1Ohm resistance. ADG5412BRUZ operates at 9V to 40V single supply with 10Ohm resistance. Selection depends on supply voltage availability and acceptable on-state resistance for the application.
Q: Are package differences between 16-SSOP and 16-TSSOP critical? A: Both are 16-pin surface mount packages with different body widths (3.90mm vs 4.40mm). PCB layout and footprint must accommodate the wider TSSOP package. Electrical performance is not affected by package geometry.
Q: Which substitute offers the best high-frequency performance? A: ADG5412BRUZ provides 160MHz -3dB bandwidth, exceeding PS392EEE (100MHz). DG455EQ-T1-E3 does not specify -3dB bandwidth but offers 118ns turn-on time. ADG1612BRUZ specifies 38MHz bandwidth, limiting high-frequency applications.
Q: What is the significance of charge injection values? A: Lower charge injection reduces signal distortion in precision switching applications. PS392EEE (3pC) has the lowest charge injection. DG455EQ-T1-E3 (22pC) is the best substitute for charge injection performance. ADG1612BRUZ (170pC) and ADG5412BRUZ (310pC) are suitable only for applications tolerant of higher charge injection.
Q: Are all substitutes available in both tube and tape & reel packaging? A: No. ADG1612BRUZ is available in tube and cut tape/digi-reel formats. ADG5412BRUZ is available in tube; ADG5412BRUZ-REEL7 is tape & reel. MAX4712 variants are available in both formats. DG455EQ-T1-E3 is tape & reel only. Verify packaging availability for production requirements.
Q: Can PS392EEE be used in applications requiring -40°C to 125°C operation? A: No. PS392EEE maximum operating temperature is 85°C. For extended temperature range, use ADG1612BRUZ, ADG5412BRUZ, or DG455EQ-T1-E3, all rated to 125°C.
