PS392CPE IC Switch SPST-NO 4 Circuit 45Ohm 16-DIP Equivalent & Substitute Parts

Part Overview

The PS392CPE is a 4-circuit SPST-NO (Single Pole Single Throw - Normally Open) IC switch manufactured by Diodes Incorporated, housed in a 16-DIP package. This component functions as an analog switch with 1:1 multiplexer/demultiplexer configuration, designed for signal routing and switching applications requiring low on-state resistance and fast switching times.

The PS392CPE is classified as obsolete. Locating equivalent or substitute parts is necessary for new designs, production continuity, and system upgrades where active component alternatives with comparable electrical and mechanical specifications are required.

Engineering Selection Recommendations

MAX392CPE+ (Recommended Primary Substitute)

The MAX392CPE+ is the closest electrical equivalent to the PS392CPE. It maintains identical supply voltage ranges (3V ~ 15V single, ±3V ~ 8V dual), identical switch timing specifications (130ns Ton, 75ns Toff), and identical operating temperature range (0°C ~ 70°C). The on-state resistance is lower at 35Ohm compared to 45Ohm, providing improved performance. The MAX392CPE+ is currently in active production status and carries ROHS3 compliance, making it suitable for new designs and production environments requiring regulatory compliance.

ALD4202MPCL (Secondary Substitute - Active Status)

The ALD4202MPCL is an active production alternative with identical package and circuit configuration. It supports the required supply voltage ranges (3V ~ 12V single, ±1.5V ~ 6V dual) and operating temperature (0°C ~ 70°C). The on-state resistance is higher at 135Ohm, which may require circuit design evaluation. Switch timing is slower (240ns Ton, 130ns Toff) compared to the PS392CPE. This part carries ROHS3 compliance and is suitable for applications where the higher on-state resistance and slower switching times are acceptable.

MAX4552CPE+ (Not Recommended)

The MAX4552CPE+ is classified as obsolete, similar to the PS392CPE. While it meets the primary substitution criteria, its obsolete status provides no advantage over the PS392CPE for new designs or long-term production continuity. This part is listed for reference only in applications requiring specific electrical characteristics (120Ohm Ron, faster Ton at 110ns).

Frequently Asked Questions (FAQ)

Q: Can I directly replace PS392CPE with MAX392CPE+ without circuit modifications?

A: The MAX392CPE+ is pin-compatible and functionally equivalent within the 16-DIP package. However, the lower on-state resistance (35Ohm vs. 45Ohm) may affect circuit behavior. Verify that your application can tolerate the improved (lower) resistance characteristic. No PCB layout changes are required due to identical package dimensions.

Q: What is the primary difference between the three substitute options?

A: The three substitutes differ primarily in on-state resistance and product status. MAX392CPE+ offers the closest match to PS392CPE specifications and is actively produced. ALD4202MPCL is also active but has higher on-state resistance and slower switching times. MAX4552CPE+ is obsolete and provides no production advantage.

Q: Are all substitute parts RoHS compliant?

A: MAX392CPE+ and ALD4202MPCL are ROHS3 compliant. The PS392CPE is RoHS non-compliant. If your application or market requires RoHS compliance, select either MAX392CPE+ or ALD4202MPCL.

Q: Does package compatibility guarantee functional compatibility?

A: Package compatibility (16-DIP through-hole) ensures mechanical and electrical pin compatibility. Functional compatibility depends on matching the electrical parameters required by your circuit design, including on-state resistance, supply voltage range, and switching speed. Review the parameter comparison table to confirm suitability for your specific application.

Q: Which substitute should I choose for a new design?

A: For new designs, MAX392CPE+ is the recommended choice. It is actively produced, ROHS3 compliant, and provides the closest electrical match to the PS392CPE with improved on-state resistance performance.

Q: Can I use ALD4202MPCL if my circuit requires faster switching times?

A: No. The ALD4202MPCL has slower switch times (240ns Ton, 130ns Toff) compared to the PS392CPE (130ns Ton, 75ns Toff). If your application requires the original switching speed, select MAX392CPE+ or MAX4552CPE+.

Q: What is the impact of higher on-state resistance in ALD4202MPCL?

A: Higher on-state resistance (135Ohm vs. 45Ohm) increases voltage drop across the switch during conduction, which may affect signal amplitude and power dissipation. Evaluate your circuit's tolerance for increased Ron before selecting this part.
