PS7206-1A-E3-A Equivalent & Substitute Parts

Part Overview

The PS7206-1A-E3-A is a Solid State Relay (SSR) manufactured by CEL, configured as a SPST-NO (1 Form A) switch in a 4-SOP surface mount package. This component functions as an optically isolated electronic switch for AC and DC loads up to 600 mA at 0–60 V. The PS7206-1A-E3-A is classified as obsolete, making identification of compatible substitute parts essential for ongoing design support and production continuity. Equivalent parts must maintain identical electrical performance parameters and mechanical compatibility to ensure direct replacement without circuit redesign.

Substitute Part Grouping Explanation

Substitution of the PS7206-1A-E3-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) solid state relays with identical switching topology.

Package and Termination: The 4-SOP (0.173", 4.40mm) surface mount package with gull wing termination is mandatory for PCB compatibility without layout modification.

Electrical Load Specifications: The substitute must support the same load voltage range (0–60 V AC/DC) and load current rating. The substitute may exceed the original current rating without creating incompatibility.

Input Voltage Compatibility: The substitute input voltage must be compatible with the control circuit driving the original part. Minor variations within the same logic family are acceptable.

On-State Resistance: The substitute's on-state resistance must not exceed the original specification to maintain thermal and power dissipation characteristics within the original design envelope.

The AQY212GSX from Panasonic Electric Works meets all substitution criteria for the PS7206-1A-E3-A.

Parameter Comparison

Engineering Selection Recommendations

The AQY212GSX is a direct functional equivalent to the PS7206-1A-E3-A for applications requiring SPST-NO solid state relay operation in the 0–60 V load range.

Product Status Advantage: The AQY212GSX is in active production status, ensuring long-term availability and supply chain stability compared to the obsolete PS7206-1A-E3-A.

Electrical Performance: The AQY212GSX provides superior electrical characteristics with a 1 A load current rating (versus 600 mA) and lower on-state resistance (700 mOhms versus 800 mOhms). These improvements enhance thermal efficiency and reduce power dissipation in the switching element.

Compliance and Certification: The AQY212GSX is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The original PS7206-1A-E3-A is REACH affected, which may present supply or documentation challenges for new designs or production batches.

Package Compatibility: Both parts use identical 4-SOP (0.173", 4.40mm) gull wing termination, enabling direct PCB footprint compatibility without layout modification.

Input Voltage: The AQY212GSX input voltage of 1.32 VDC is compatible with control circuits designed for the 1.2 VDC PS7206-1A-E3-A, with negligible impact on gate drive requirements.

Frequently Asked Questions (FAQ)

Q: Can the AQY212GSX replace the PS7206-1A-E3-A in existing designs without PCB modification?

A: Yes. Both parts use the 4-SOP (0.173", 4.40mm) package with gull wing termination. The footprint and pinout are identical, allowing direct substitution without PCB layout changes.

Q: What is the significance of the higher load current rating (1 A) on the AQY212GSX compared to the 600 mA specification of the PS7206-1A-E3-A?

A: The higher current rating indicates the AQY212GSX can handle greater load current without exceeding its maximum operating conditions. In applications limited to 600 mA or less, this provides additional design margin and thermal headroom.

Q: Are there differences in input voltage requirements between these two parts?

A: The PS7206-1A-E3-A specifies 1.2 VDC input, while the AQY212GSX specifies 1.32 VDC input. This 0.12 VDC difference is within typical gate drive tolerances and does not require control circuit modification for standard logic-level inputs.

Q: Why is the on-state resistance lower on the AQY212GSX (700 mOhms) than the PS7206-1A-E3-A (800 mOhms)?

A: Lower on-state resistance reduces power dissipation during the on-state, resulting in lower junction temperature and improved thermal performance. This is a beneficial characteristic for the substitute part.

Q: What is the impact of the PS7206-1A-E3-A being obsolete?

A: Obsolete status indicates the part is no longer manufactured or supported by the original supplier. The AQY212GSX, being in active production, ensures availability for new production runs, repairs, and design updates.

Q: Does the REACH compliance difference affect substitution?

A: The PS7206-1A-E3-A is REACH affected, meaning it may contain substances of concern requiring documentation and compliance verification. The AQY212GSX is REACH unaffected, simplifying regulatory compliance for new designs and production batches.

Q: Are both parts suitable for AC and DC load switching?

A: Yes. Both the PS7206-1A-E3-A and AQY212GSX support AC and DC output types across the 0–60 V load voltage range.
