PS7360-1A-A Solid State Relay SPST-NO Equivalent & Substitute Parts

Part Overview

The PS7360-1A-A is a Solid State Relay (SSR) manufactured by CEL, configured as a Single Pole Single Throw Normally Open (SPST-NO) device in a 6-DIP through-hole package. This component operates with a 1.2VDC input signal and switches loads up to 600V AC/DC at 90mA maximum current. The PS7360-1A-A is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system maintenance, repair, and new design implementations where legacy component replacement is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS7360-1A-A is determined by strict equivalence across the following critical parameters:

Circuit Configuration: Both the main part and substitute must be SPST-NO (1 Form A) to maintain identical switching topology and control logic compatibility.

Package and Mounting: The 6-DIP (0.300", 7.62mm) through-hole package with PC pin termination is mandatory for direct board-level replacement without redesign.

Electrical Specifications: Input voltage (1.2VDC), load voltage range (0V ~ 600V AC/DC), and on-state resistance (50 Ohms maximum) must be matched or exceeded in performance capability.

Load Current Rating: The substitute must support the required 90mA load current. A substitute with equal or higher current rating (100mA or greater) is acceptable and provides operational margin.

Output Type: AC/DC output capability must be maintained to preserve compatibility with existing load switching requirements.

The PLA193 manufactured by IXYS Integrated Circuits Division meets all substitution criteria and is classified as an active product with current manufacturing support.

Engineering Selection Recommendations

The PLA193 is the qualified substitute for the obsolete PS7360-1A-A based on the following engineering criteria:

Functional Equivalence: All critical electrical and mechanical parameters are identical or superior. The PLA193 load current rating of 100mA exceeds the PS7360-1A-A requirement of 90mA, providing operational margin without performance degradation.

Package Compatibility: Both devices use the 6-DIP (0.300", 7.62mm) through-hole package with PC pin termination, enabling direct board-level replacement without PCB redesign or layout modification.

Product Status and Supply: The PLA193 is classified as an active product with current manufacturing support, ensuring long-term availability and supply chain continuity. The PS7360-1A-A is obsolete and subject to inventory depletion.

Regulatory Compliance: The PLA193 is ROHS3 compliant and REACH unaffected, providing superior environmental and regulatory compliance compared to the PS7360-1A-A, which is REACH affected. This substitution improves overall system compliance posture.

Electrical Performance: On-state resistance, input voltage, load voltage range, and output type specifications are fully matched, ensuring equivalent circuit behavior and system performance.

Frequently Asked Questions (FAQ)

Q: Can the PLA193 be used as a direct replacement for the PS7360-1A-A without PCB modification?

A: Yes. Both devices share identical package specifications (6-DIP, 0.300" spacing, PC pin termination) and pinout compatibility, enabling direct through-hole board replacement without layout changes.

Q: What is the significance of the higher 100mA load current rating on the PLA193 compared to the 90mA rating of the PS7360-1A-A?

A: The PLA193's 100mA rating exceeds the PS7360-1A-A's 90mA requirement, providing operational margin and thermal headroom. This higher rating does not create compatibility issues; it ensures the substitute can handle the specified load with additional capacity.

Q: Are there differences in control signal requirements between these two SSR relays?

A: No. Both devices require identical 1.2VDC input control signals and operate with the same SPST-NO (1 Form A) switching logic. No control circuit modifications are necessary.

Q: Why is the REACH compliance status different between the two parts?

A: The PLA193 is manufactured to current REACH regulations and is classified as REACH unaffected. The PS7360-1A-A, being an older obsolete product, is REACH affected. Substitution with the PLA193 improves regulatory compliance for new designs and system upgrades.

Q: Is the PLA193 suitable for both AC and DC load switching applications?

A: Yes. The PLA193 supports AC and DC output types, matching the PS7360-1A-A capability. Load voltage range (0V ~ 600V) is identical for both AC and DC applications.

Q: What is the moisture sensitivity level (MSL) for the PLA193?

A: The PLA193 has an MSL rating of 1 (Unlimited), identical to the PS7360-1A-A. Both devices have unlimited shelf life and do not require moisture-controlled storage or handling.

Q: Are there any thermal or reliability differences between the OCMOS technology of the PS7360-1A-A and the OptoMOS® technology of the PLA193?

A: Both technologies are solid-state relay implementations with equivalent on-state resistance (50 Ohms maximum) and electrical performance. The PLA193's OptoMOS® technology is actively manufactured and supported, while the PS7360-1A-A's OCMOS technology is obsolete.
