PVG612S Solid State Relay - Equivalent & Substitute Parts

Part Overview

The PVG612S is a solid state relay (SSR) manufactured by Infineon Technologies, configured as a SPST-NO (Single Pole Single Throw - Normally Open) relay with 1A load current capacity and 0-60V output voltage range. This component is classified as obsolete, which necessitates identification of equivalent and substitute parts for ongoing design requirements and production continuity.

Substitute Part Grouping Explanation

Substitution of the PVG612S is determined by the following critical parameters:

Circuit Configuration: Must be SPST-NO (1 Form A) to maintain functional equivalence
Load Voltage Range: Must support 0-60V output voltage specification
Load Current: Must support minimum 1A continuous current
Package Compatibility: Surface mount packages with gull wing termination are preferred for PCB compatibility
Output Type: AC/DC capability preferred to maintain design flexibility

Substitute parts are grouped into two categories:

Direct Equivalent (Same Manufacturer): PVG612SPBF maintains identical electrical specifications with active product status and improved RoHS3 compliance.

Functional Equivalents (Alternative Manufacturers): Panasonic Electric Works PhotoMOS™ series relays (AQV and AQY families) provide SPST-NO configurations with compatible voltage and current ratings. These parts meet or exceed the electrical requirements of the PVG612S while offering active product status and modern compliance certifications.

Engineering Selection Recommendations

Primary Recommendation: PVG612SPBF is the direct equivalent replacement for PVG612S. This part maintains identical electrical specifications and package configuration while offering active product status and ROHS3 compliance certification. No design modifications are required for this substitution.

Alternative Selections Based on Application Requirements:

AQV252GAX: Select when load current exceeds 1A or when lower on-state resistance (120 mOhms) is beneficial for thermal management. Maintains 0-60V voltage range and 6-SMD package compatibility.
AQV102A: Select for applications where load current is 600mA or less. Provides 0-60V voltage range with 6-SMD package. On-state resistance of 700 mOhms is acceptable for lower current applications.
AQY211EHAX: Select when load voltage does not exceed 30V and 1A current is required. Offers reduced package footprint (4-SMD) with identical on-state resistance to the original part.
AQV212S and AQV252AX: Select only when load current requirements are 500mA or less. Package size reduction (6-SOP) may require PCB layout modifications.

Avoid: AQY212FG2S, AQY212FG2SX, and AQW612EHA are obsolete or have non-standard configurations (dual form relay) and should not be selected for new designs.

Frequently Asked Questions (FAQ)

Q: Can PVG612SPBF be used as a direct drop-in replacement for PVG612S?

A: Yes. PVG612SPBF is electrically and mechanically identical to PVG612S with the same 6-SMD package, gull wing termination, and electrical specifications. No PCB modifications are required.

Q: What is the primary difference between PVG612S and PVG612SPBF?

A: PVG612SPBF has active product status and ROHS3 compliance certification, whereas PVG612S is obsolete and RoHS non-compliant. The electrical performance is identical.

Q: Can I use AQV252GAX if my application only requires 1A load current?

A: Yes. AQV252GAX is rated for 2.5A continuous current, which exceeds the 1A requirement. The part will operate reliably at lower current levels. The lower on-state resistance (120 mOhms vs. 500 mOhms) provides improved thermal performance.

Q: Are Panasonic PhotoMOS™ relays pin-compatible with the PVG612S?

A: No. While Panasonic relays provide equivalent electrical function, pin configurations differ. PCB layout modifications are required for most Panasonic substitutes except where package type is identical (6-SMD).

Q: What is the significance of the 6-SMD versus 4-SMD package designation?

A: The first number indicates the pin count. 6-SMD has six pins, while 4-SMD has four pins. These are not interchangeable without PCB redesign. The PVG612S uses 6-SMD packaging.

Q: Can I substitute AQV212S for PVG612S in my design?

A: AQV212S provides SPST-NO functionality with 0-60V voltage range but has reduced load current (500mA vs. 1A) and uses a different package (6-SOP vs. 6-SMD). Substitution is only valid if your application requires 500mA or less and PCB layout can accommodate the smaller package footprint.

Q: Why are some substitute parts listed as obsolete?

A: AQY212FG2S and AQY212FG2SX are included for reference only as they appear in the original PVG612S substitute list. These parts should not be selected for new designs due to obsolete status. Active alternatives with superior compliance are available.
