PS7206-1A-A Solid State Relay SPST-NO Equivalent & Substitute Parts

Part Overview

The PS7206-1A-A is a solid state relay (SSR) manufactured by CEL in the PS/OCMOS series. This component is a SPST-NO (Single Pole Single Throw - Normally Open) relay with 1 Form A configuration, rated for 600 mA load current at 0-60V output voltage. The device features surface mount technology in a 4-SOP package with gull wing termination.

The PS7206-1A-A is classified as obsolete. Equivalent and substitute parts are necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this solid state relay topology.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS7206-1A-A is determined by strict alignment of the following critical parameters:

Circuit Configuration: All substitute parts must maintain SPST-NO (1 Form A) topology to ensure functional equivalence in switching applications.

Output Voltage Range: All substitutes must support 0-60V load voltage to maintain compatibility with existing circuit designs.

Mounting and Package: Surface mount technology with 4-SOP or 6-SOP package footprints and gull wing termination are acceptable, as these are mechanically compatible within standard PCB assembly processes.

Input Voltage: Substitute parts operate at input voltages between 1.14 VDC and 1.32 VDC, which are functionally compatible with the original 1.2 VDC specification.

Load Current Capability: Substitute parts are grouped by load current rating. Parts rated at 500 mA are suitable for applications requiring ≤500 mA. The AQY212GS, rated at 1 A, is suitable for applications requiring up to 600 mA.

On-State Resistance: Substitute parts exhibit on-state resistance values ranging from 700 mOhms to 2.5 Ohms. Lower resistance values indicate improved thermal performance and reduced power dissipation.

All substitute parts are manufactured by Panasonic Electric Works in the PhotoMOS™ series and maintain active product status with RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring 600 mA load current: The AQY212GS is the primary substitute. This part is rated for 1 A continuous load current, exceeding the original 600 mA specification. It maintains the 4-SOP package footprint, identical load voltage range (0-60V), and on-state resistance of 700 mOhms, which is superior to the original 800 mOhms. The AQY212GS is active product status with ROHS3 compliance.

For applications with reduced load current requirements (≤500 mA): The AQY222R1SZ and AQY222R1SX are suitable substitutes. Both parts are rated for 500 mA and feature on-state resistance of 1.2 Ohms. The AQY222R1SZ is available in Tape & Reel packaging with higher inventory (20,100 pcs), while AQY222R1SX is available in Cut Tape & Digi-Reel® packaging. Both support AC/DC (RF) output capability and maintain 4-SOP package compatibility.

For package footprint flexibility: The AQV212S provides a 6-SOP alternative with 500 mA rating. This part is suitable only when PCB layout permits the larger 6-SOP footprint. On-state resistance is 2.5 Ohms, which represents increased power dissipation compared to other substitutes.

For standard 500 mA applications: The AQY212S offers 4-SOP package compatibility with 500 mA rating and 2.5 Ohms on-state resistance. This part is active status with ROHS3 compliance and Tube packaging.

All substitute parts maintain the ECCN EAR99 classification and HTSUS code 8536.41.0030, consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can the AQY212GS directly replace the PS7206-1A-A in all applications?

A: The AQY212GS is functionally compatible for applications requiring up to 600 mA load current. It maintains identical load voltage range (0-60V), SPST-NO circuit configuration, and 4-SOP package footprint. The superior on-state resistance (700 mOhms vs. 800 mOhms) and higher current rating (1 A vs. 600 mA) make it suitable for direct substitution. Verify input voltage compatibility (1.32 VDC vs. 1.2 VDC) with your control circuit.

Q: What is the difference between AQY222R1SZ and AQY222R1SX?

A: Both parts are electrically identical with 500 mA rating, 1.2 Ohms on-state resistance, and AC/DC (RF) output capability. The primary difference is packaging: AQY222R1SZ is supplied in Tape & Reel format with 20,100 pcs inventory, while AQY222R1SX is supplied in Cut Tape & Digi-Reel® format with 1,186 pcs inventory. Select based on assembly process requirements and volume needs.

Q: Why do some substitutes have higher on-state resistance values?

A: On-state resistance varies by manufacturer design and series. The AQY212S and AQV212S feature 2.5 Ohms on-state resistance, while AQY222R1SZ and AQY222R1SX feature 1.2 Ohms. Lower resistance reduces power dissipation and heat generation during operation. For thermal-sensitive applications, select parts with lower on-state resistance values.

Q: Is the 6-SOP package of AQV212S compatible with the original 4-SOP footprint?

A: No. The AQV212S uses a 6-SOP package, which has a different pin count and footprint than the original 4-SOP. PCB redesign is required for this substitution. Use AQV212S only when PCB layout modifications are acceptable or when the larger package provides design advantages.

Q: Are all substitute parts RoHS compliant?

A: Yes. All Panasonic PhotoMOS™ substitute parts (AQV212S, AQY212GS, AQY212S, AQY222R1SX, AQY222R1SZ) are RoHS3 compliant or RoHS compliant, meeting environmental regulatory requirements.

Q: What is the significance of AC/DC (RF) output type in AQY222R1SX and AQY222R1SZ?

A: The AC/DC (RF) designation indicates these parts are optimized for radiofrequency and high-frequency switching applications. For standard AC/DC switching applications, this capability is not required but does not restrict use in conventional circuits.

Q: Can I use a 500 mA rated part in an application requiring 600 mA?

A: No. Using a 500 mA rated part in a 600 mA application exceeds the component's rated load current and creates risk of thermal stress, reduced component life, and potential failure. Use only AQY212GS (1 A rating) for 600 mA applications, or reduce circuit load current to ≤500 mA for other substitutes.
