PS7206-1A Solid State Relay - Equivalent & Substitute Parts

Part Overview

The PS7206-1A is a Surface Mount Solid State SPST-NO (1 Form A) relay manufactured by CEL, designed for switching applications requiring 600 mA load current at 0-60V output voltage with 1.2VDC input control. The device is packaged in a 4-SOP (0.173", 4.40mm) configuration with Gull Wing termination style.

This part 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 applications currently utilizing the PS7206-1A.

Substitute Part Grouping Explanation

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

Mandatory Compatibility Criteria:

Circuit Configuration: SPST-NO (1 Form A) - all substitutes must maintain identical switching topology
Output Type: AC, DC - substitutes must support both AC and DC load switching
Voltage - Load: 0 V ~ 60 V - substitutes must support the full 60V load voltage range
Mounting Type: Surface Mount - substitutes must be compatible with PCB surface mount assembly processes
Package / Case: 4-SOP (0.173", 4.40mm) - substitutes must use identical or mechanically compatible packaging
Termination Style: Gull Wing - substitutes must use Gull Wing leads for direct footprint compatibility

Allowable Parameter Variations:

Voltage - Input: May vary within reasonable control signal ranges (1.14VDC to 1.32VDC acceptable)
Load Current: May equal or exceed 600 mA requirement
On-State Resistance: May be lower than 800 mOhms (improved performance)
Manufacturer: Alternative qualified manufacturers acceptable

Substitutes are grouped by mounting compatibility and package form factor. Surface Mount 4-SOP devices with matching load voltage range and SPST-NO configuration are direct substitutes.

Engineering Selection Recommendations

Direct Substitutes (Identical Mounting and Package):

The ASSR-1410-003E (Broadcom Limited) is the primary direct substitute for the PS7206-1A. Both devices share identical 4-SOP (0.173", 4.40mm) Surface Mount packaging with Gull Wing termination, matching load voltage range (0-60V), and equivalent load current (600 mA). The ASSR-1410-003E is currently in Active product status with ROHS3 compliance and REACH Unaffected certification, ensuring long-term supply availability and regulatory compliance.

The AQY212GS (Panasonic Electric Works, PhotoMOS™ AQY series) provides an alternative direct substitute with identical package and mounting configuration. This device exceeds the load current requirement (1 A vs. 600 mA) and offers improved on-state resistance (700 mOhms vs. 800 mOhms). The AQY212GS is Active status with ROHS3 compliance.

The AQY212S (Panasonic Electric Works, PhotoMOS™ AQY series) is a direct package substitute with identical 4-SOP configuration and 0-60V load voltage range. However, this device provides 500 mA load current, which is below the PS7206-1A specification of 600 mA. Selection of AQY212S is appropriate only for applications where the actual load current requirement is 500 mA or less.

Alternative Substitutes (Different Mounting or Package):

The AQV212S (Panasonic Electric Works, PhotoMOS™ AQV series) uses a 6-SOP package variant with identical 0.173" (4.40mm) body width but different pin configuration. This device requires PCB layout modification and is suitable only when design flexibility permits package change.

The AQV201 and AQV251 (Panasonic Electric Works, PhotoMOS™ AQV series) use Through Hole 6-DIP packaging, requiring significant PCB redesign. These devices are not recommended for direct substitution of the Surface Mount PS7206-1A without comprehensive design revision.

Compliance and Supply Status:

All recommended substitutes (ASSR-1410-003E, AQY212GS, AQY212S) are Active status products with ROHS3 compliance and REACH Unaffected certification, providing regulatory compliance and supply chain continuity superior to the Obsolete PS7206-1A.

Frequently Asked Questions (FAQ)

Q: Can the ASSR-1410-003E directly replace the PS7206-1A without PCB modification?

A: Yes. The ASSR-1410-003E shares identical 4-SOP (0.173", 4.40mm) Surface Mount packaging with Gull Wing termination, matching the PS7206-1A footprint exactly. No PCB layout changes are required for mechanical compatibility.

Q: What is the difference between AQY212GS and AQY212S?

A: Both devices use identical 4-SOP packaging and 0-60V load voltage range. The primary difference is load current rating: AQY212GS provides 1 A while AQY212S provides 500 mA. For applications requiring 600 mA, the AQY212GS is the appropriate selection.

Q: Why are AQV201 and AQV251 listed as substitutes if they use different packages?

A: These devices are listed as substitutes from the original manufacturer specification but are not recommended for direct replacement due to Through Hole 6-DIP packaging, which requires PCB redesign. They are included for reference only in applications where design modification is feasible.

Q: Does the AQY212S meet the 600 mA load current requirement?

A: No. The AQY212S is rated for 500 mA maximum load current, which is below the PS7206-1A specification of 600 mA. This device is suitable only for applications where actual load current does not exceed 500 mA.

Q: What is the input voltage tolerance for substitute selection?

A: The PS7206-1A requires 1.2VDC input. Acceptable substitutes operate at 1.14VDC to 1.32VDC input, representing a ±10% tolerance range. All listed substitutes fall within this acceptable range and are compatible with standard control signal sources.

Q: Are all substitute parts RoHS compliant?

A: The PS7206-1A is RoHS non-compliant (Obsolete status). All recommended substitutes (ASSR-1410-003E, AQY212GS, AQY212S) are ROHS3 compliant, providing improved environmental and regulatory compliance for new designs and production.

Q: What is the on-state resistance difference between PS7206-1A and ASSR-1410-003E?

A: The PS7206-1A specifies 800 mOhms maximum on-state resistance, while the ASSR-1410-003E specifies 1 Ohm maximum. This 200 mOhm difference is negligible for most switching applications and represents acceptable performance variation within the SSR relay category.

Q: Can I use AQV212S as a substitute if my PCB already has 6-SOP footprints?

A: Yes. If your PCB design already accommodates 6-SOP packaging, the AQV212S provides a compatible substitute with matching 0-60V load voltage range and SPST-NO configuration. However, verify that your PCB footprint matches the 6-SOP (0.173", 4.40mm) specification exactly.
