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

Part Overview

The PS7360-1A 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 at 90mA, supporting both AC and DC output applications. The PS7360-1A is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations where this specific model is no longer available from inventory or production.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PS7360-1A is determined by strict alignment with the following core parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPST-NO (1 Form A)
• Package type: 6-DIP (0.300", 7.62mm)
• Mounting type: Through Hole
• Termination style: PC Pin
• Load voltage range: 0V to 600V
• Output type: AC and DC capability
• Input voltage: 1.2VDC nominal

Allowable Variation Parameters:

• Load current: Must equal or exceed 90mA
• On-state resistance: Must not exceed 50 Ohms (lower values acceptable)
• Input voltage: Minor deviations acceptable if within component tolerance

The identified substitute parts meet these criteria with the following distinctions:

PLA143 (Littelfuse): Direct substitute with enhanced load current rating (100mA vs. 90mA) and identical on-state resistance (50 Ohms). Active product status with RoHS3 compliance.

AQV216EH (Panasonic Electric Works): Similar substitute with reduced load current rating (50mA vs. 90mA) and increased on-state resistance (120 Ohms vs. 50 Ohms). Active product status with RoHS compliance. Suitable only for applications with load current requirements ≤50mA.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: PLA143 (Littelfuse)

The PLA143 is the preferred direct substitute for the PS7360-1A. It maintains identical electrical specifications for on-state resistance (50 Ohms maximum) and load voltage range (0V to 600V), with an enhanced load current rating of 100mA that exceeds the original 90mA specification. The PLA143 is classified as an active product with RoHS3 compliance, ensuring long-term availability and regulatory alignment. The OptoMOS® series designation indicates modern solid-state relay technology with proven reliability in industrial applications.

Secondary Substitute: AQV216EH (Panasonic Electric Works)

The AQV216EH is a similar substitute suitable only for applications where the load current requirement does not exceed 50mA. This component exhibits increased on-state resistance (120 Ohms maximum) compared to the PS7360-1A specification (50 Ohms maximum), which may result in higher power dissipation in the relay itself. The AQV216EH is an active product with RoHS compliance and represents Panasonic's PhotoMOS™ AQV series technology. Selection of this part requires verification that the 50mA load current ceiling and 120 Ohms on-state resistance are compatible with the target application's electrical requirements.

Compliance Considerations

Both substitute parts are active products with current RoHS compliance certifications, addressing the non-compliant status of the obsolete PS7360-1A. Both parts carry the same ECCN (EAR99) and HTSUS (8536.41.0030) classifications as the original component.

Frequently Asked Questions (FAQ)

Q: Can the PLA143 be used as a direct replacement for the PS7360-1A without circuit modifications?

A: Yes. The PLA143 maintains identical package geometry (6-DIP, 0.300" spacing), termination style (PC Pin), input voltage (1.2VDC), load voltage range (0V to 600V), and on-state resistance (50 Ohms maximum). The enhanced load current rating (100mA vs. 90mA) provides additional margin without requiring circuit changes.

Q: What is the primary limitation of the AQV216EH as a substitute?

A: The AQV216EH has a maximum load current rating of 50mA, which is 40mA below the PS7360-1A specification of 90mA. Additionally, its on-state resistance is 120 Ohms maximum, compared to 50 Ohms for the PS7360-1A. These parameters limit its use to applications with lower current demands and higher acceptable power dissipation in the relay element.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 6-DIP (0.300", 7.62mm) package with PC Pin termination, ensuring mechanical and electrical pin compatibility on standard through-hole PCB layouts.

Q: What is the difference between the input voltage specifications of 1.2VDC (PS7360-1A, PLA143) and 1.14VDC (AQV216EH)?

A: The 1.14VDC input voltage of the AQV216EH represents a minor variation within typical component tolerance ranges. Both values are functionally equivalent for standard logic-level control signals (3.3V, 5V, 12V) used to drive these relays.

Q: Does the obsolete status of the PS7360-1A affect the validity of the PLA143 and AQV216EH as substitutes?

A: No. The obsolete status of the PS7360-1A indicates that the original component is no longer manufactured or stocked by CEL. The PLA143 and AQV216EH are active products with confirmed current availability, making them suitable for both replacement applications and new designs requiring SPST-NO solid state relay functionality in the 6-DIP package.

Q: Are there any differences in moisture sensitivity between these parts?

A: The PS7360-1A and PLA143 both have MSL (Moisture Sensitivity Level) rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. The AQV216EH has MSL listed as Not Applicable, which also indicates no moisture sensitivity concerns. All three parts are suitable for standard storage and handling conditions.
