Key Parameters

Substitute Part Grouping Explanation

The PS7206-1A-F3-A identifies one qualified substitute based on compatibility across the following critical parameters:

• Circuit Configuration: Both the main part and substitute maintain identical SPST-NO (1 Form A) switching topology, ensuring functional equivalence in single-pole, single-throw applications.
• Package and Footprint: Both components utilize 4-SOP (0.173", 4.40mm) surface mount packaging with gull wing termination, enabling direct PCB layout compatibility without redesign.
• Electrical Operating Range: Load voltage range (0 V ~ 60 V) and output type (AC, DC) remain consistent across both parts.
• Load Current Rating: The substitute part (AQY212GSX) provides 1 A maximum load current, which is sufficient for and exceeds the original 600 mA specification.
• Input Voltage Compatibility: The substitute input voltage specification (1.32 VDC) is functionally compatible with the original 1.2 VDC requirement.
• On-State Resistance: The substitute part exhibits lower resistance (700 mOhms maximum) compared to the original (800 mOhms maximum), representing an improvement in conduction characteristics.

Parameter Comparison

Engineering Selection Recommendations

The AQY212GSX from Panasonic Electric Works qualifies as a suitable substitute for the obsolete PS7206-1A-F3-A based on the following engineering criteria:

Mechanical Compatibility: Both components share identical package geometry (4-SOP 0.173" / 4.40mm) and gull wing termination, supporting direct PCB footprint compatibility and eliminating layout redesign requirements.

Electrical Compatibility: The AQY212GSX maintains the same load voltage operating range (0 V ~ 60 V) and supports both AC and DC output switching. The substitute's input voltage specification (1.32 VDC) overlaps functionally with the original design point (1.2 VDC), assuming standard input signal tolerance margins in the design.

Load Current Headroom: The AQY212GSX provides 1 A maximum load current capacity, exceeding the original 600 mA specification. This provides margin for circuit variations and aging effects.

On-State Resistance Improvement: The AQY212GSX exhibits 700 mOhms maximum resistance compared to 800 mOhms for the original part, reducing conduction losses and heat generation.

Regulatory and Supply Status: The AQY212GSX carries Active product status with ROHS3 compliance certification, ensuring long-term supply chain availability and regulatory alignment for new designs and production restarts.

Frequently Asked Questions (FAQ)

Q: Will the AQY212GSX function as a direct replacement on existing PS7206-1A-F3-A circuit boards?

A: Yes. Both components utilize identical 4-SOP (0.173", 4.40mm) surface mount packaging with gull wing termination. The footprints are mechanically compatible, requiring no PCB design modifications for substitution.

Q: How do the electrical specifications of the AQY212GSX compare to the PS7206-1A-F3-A?

A: The AQY212GSX maintains load voltage range (0 V ~ 60 V) and output capability (AC, DC) identical to the original. Input voltage (1.32 VDC vs. 1.2 VDC) and load current (1 A vs. 600 mA) both meet or exceed original specifications. On-state resistance is improved (700 mOhms vs. 800 mOhms).

Q: What load current tolerance margin does the AQY212GSX provide?

A: The AQY212GSX provides a 400 mA margin above the original 600 mA design specification, with a maximum rating of 1 A. This headroom accommodates circuit variations and component aging over the product lifetime.

Q: Are there any compliance differences between the PS7206-1A-F3-A and AQY212GSX?

A: The AQY212GSX carries ROHS3 compliance certification. Both components share identical REACH Unaffected status and EAR99 ECCN classification, meeting equivalent regulatory requirements for industrial applications.

Q: Is the AQY212GSX available in the same packaging formats?

A: The AQY212GSX is available in Cut Tape (CT) and Digi-Reel packaging formats, supporting both manual and automated assembly workflows. The original PS7206-1A-F3-A specification did not designate specific tape formats, making the broader availability advantageous for production scaling.

Q: What is the basis for recommending the AQY212GSX over other SPST-NO relay options?

A: The AQY212GSX qualifies as a substitute based on strict electrical and mechanical parameter matching: identical circuit topology (SPST-NO), matching package footprint (4-SOP gull wing), overlapping voltage specifications, and equivalent or superior load current and resistance characteristics. These parameters define substitutability for this component category.
