PS7200K-1A-A Solid State Relay SPST-NO Equivalent & Substitute Parts

Part Overview

The PS7200K-1A-A is a solid state relay (SSR) manufactured by CEL, configured as a single-pole single-throw normally open (SPST-NO) switch with a 1 Form A circuit. This component is designed for switching applications requiring 200 mA load current at 0-40V output voltage with a 1.2VDC input signal. The device features surface mount packaging in a 4-SOP form factor with gull wing termination.

The PS7200K-1A-A is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS7200K-1A-A is determined by strict equivalence across the following critical parameters:

Circuit and Electrical Compatibility:

• Circuit configuration must be SPST-NO (1 Form A)
• Output type must support both AC and DC switching
• Load voltage range must encompass 0-40V operation
• Load current capability must meet or exceed 200 mA
• Input voltage must be compatible with 1.2VDC signal levels

Physical and Mechanical Compatibility:

• Package type must be 4-SOP (0.173", 4.40mm)
• Termination style must be gull wing
• Mounting type must be surface mount

Compliance and Regulatory:

• ECCN classification must be EAR99
• HTSUS code must be 8536.41.0030

The AQY221R2S from Panasonic Electric Works meets all substitution criteria and is classified as an active product, providing improved availability compared to the obsolete PS7200K-1A-A.

Parameter Comparison

Engineering Selection Recommendations

The AQY221R2S is a direct substitute for the PS7200K-1A-A based on electrical, mechanical, and regulatory parameter equivalence. The following factors support this substitution:

Product Status: The AQY221R2S is classified as active, whereas the PS7200K-1A-A is obsolete. This transition ensures long-term supply chain viability and access to current manufacturing processes.

Electrical Performance: The AQY221R2S provides enhanced electrical characteristics, including higher load current capability (250 mA versus 200 mA) and lower on-state resistance (1.25 Ohms versus 2 Ohms). These improvements result in reduced power dissipation and increased switching headroom for the application.

Compliance: Both components share identical ECCN (EAR99) and HTSUS (8536.41.0030) classifications. The AQY221R2S is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Physical Compatibility: Identical package specifications (4-SOP, 0.173", 4.40mm) and gull wing termination ensure direct PCB footprint compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the AQY221R2S directly replace the PS7200K-1A-A without PCB modifications?

A: Yes. Both components use identical 4-SOP (0.173", 4.40mm) packages with gull wing termination. PCB footprints are compatible without modification.

Q: What is the significance of the higher load current rating (250 mA) on the AQY221R2S?

A: The AQY221R2S load current rating of 250 mA exceeds the PS7200K-1A-A specification of 200 mA. This provides additional switching capacity and operational margin for the application. The component will function correctly in circuits designed for 200 mA operation.

Q: Are the input voltage specifications compatible?

A: Yes. The PS7200K-1A-A requires 1.2VDC input, while the AQY221R2S requires 1.14VDC input. Both specifications are compatible with standard logic-level signal sources. The AQY221R2S exhibits slightly lower input voltage requirements.

Q: What does "RF" in the AQY221R2S output type designation mean?

A: The "RF" designation indicates radio frequency capability, representing an enhanced specification of the AQY221R2S. This does not affect substitution compatibility for standard AC/DC switching applications.

Q: Are there regulatory or compliance differences between these components?

A: Both components share identical ECCN (EAR99) and HTSUS (8536.41.0030) classifications. The AQY221R2S is RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the difference in on-state resistance between these components?

A: The PS7200K-1A-A has a maximum on-state resistance of 2 Ohms, while the AQY221R2S has a maximum of 1.25 Ohms. Lower on-state resistance reduces power dissipation and heat generation during switching operation, providing improved thermal performance.

Q: Is the AQY221R2S available in the same packaging format?

A: Yes. The AQY221R2S is supplied in tube packaging, while the PS7200K-1A-A was supplied with standard packaging. Both components use the identical 4-SOP (0.173", 4.40mm) case style with gull wing termination.
