PVG612AS Solid State Relay SPST-NO Equivalent & Substitute Parts
Part Overview
The PVG612AS is a surface mount solid state relay manufactured by Infineon Technologies, featuring SPST-NO (1 Form A) switching configuration with 2A load current capacity and 0-60V output voltage range. This component is classified as obsolete, necessitating identification of active equivalent and substitute parts for new designs and production continuity. Substitute parts must maintain functional compatibility across input voltage, load voltage, load current, and package specifications while meeting modern RoHS compliance requirements.

Substitute Part Grouping Explanation
Substitution eligibility is determined by the following critical parameters: circuit configuration (SPST-NO), output type (AC/DC), input voltage (1.2VDC nominal), load voltage range (0-60V), load current (2A minimum), package type (6-SMD or compatible), and mounting method (surface mount). Parts are grouped into three categories based on parameter alignment:
Category 1: Direct Package Match (6-SMD) Parts maintaining identical 6-SMD (0.300", 7.62mm) package with load current ≥2A and load voltage ≥60V.
Category 2: Compatible Package Variants (6-SOP, 6-SMD) Parts with equivalent or smaller package footprints, load current ≥2A, and load voltage ≥50V, requiring PCB layout verification.
Category 3: Reduced Specification Match (4-SOP) Parts with reduced load voltage or current ratings, suitable only for applications with lower electrical requirements.

Engineering Selection Recommendations
Primary Recommendation: PVG612ASPBF Direct functional equivalent with identical electrical specifications and 6-SMD package. Achieves ROHS3 compliance and active product status. Requires no circuit redesign or PCB layout modification. Recommended for direct replacement in existing designs.
Secondary Recommendations (6-SMD Package, Full Voltage Range 0-60V): ASSR-1611-301E, CS136, and LCA715STR maintain 6-SMD package compatibility with 0-60V load voltage range. ASSR-1611-301E provides matched on-state resistance (100 mOhms) and enhanced load current (2.5A). CS136 and LCA715STR offer higher load current margins with increased on-state resistance. All achieve ROHS3 compliance and active product status.
Alternative Recommendations (6-SMD Package, Reduced Voltage Range): AQV252GA and AQV252GAZ maintain 6-SMD package with full 0-60V load voltage range and 2.5A load current. Suitable for applications where Panasonic PhotoMOS technology is preferred. Both achieve ROHS3 compliance and active product status.
Limited Scope Alternatives (Reduced Specifications): AQY211G2SX and C226S feature reduced load voltage (0-40V) and smaller 4-SOP packages. Applicable only to applications with maximum load voltage ≤40V. Not recommended for designs requiring full 60V load voltage capability.
Frequently Asked Questions (FAQ)
Q: Can PVG612ASPBF directly replace PVG612AS without PCB modification? A: Yes. PVG612ASPBF is the active equivalent with identical electrical specifications and 6-SMD package dimensions. No circuit or layout changes are required.
Q: What is the primary reason for substitution? A: PVG612AS is classified as obsolete. PVG612ASPBF provides continuity with active product status and ROHS3 compliance.
Q: Are ASSR-1611-301E and CS136 suitable for applications requiring 60V load voltage? A: Yes. Both parts support 0-60V load voltage range. ASSR-1611-301E provides on-state resistance matching the original specification (100 mOhms). CS136 exhibits higher on-state resistance (140 mOhms), which may increase power dissipation in high-current applications.
Q: Why do AQV252GA and AQV252GAZ have different part numbers? A: Both parts are electrically identical. AQV252GA is packaged in Tube; AQV252GAZ is packaged in Tape & Reel (TR). Selection depends on procurement and assembly requirements.
Q: Can AQY211G2SX replace PVG612AS in all applications? A: No. AQY211G2SX is limited to 0-40V load voltage and 1.6A load current, with 4-SOP package. Suitable only for applications with maximum load voltage ≤40V and current ≤1.6A.
Q: What is the impact of on-state resistance variation among substitutes? A: On-state resistance directly affects power dissipation and thermal performance. Higher resistance increases heat generation. For 2A load current, resistance variation from 70 mOhms to 150 mOhms produces power dissipation ranging from 0.28W to 0.6W. Verify thermal design margins for applications with elevated ambient temperatures.
Q: Are all substitute parts RoHS compliant? A: All substitute parts listed achieve ROHS3 compliance. The original PVG612AS is RoHS non-compliant. Compliance verification is required for applications subject to RoHS regulations.
Q: What package considerations apply to 6-SOP alternatives? A: AQV252G2SX uses 6-SOP (0.173", 4.40mm) package, which is smaller than the original 6-SMD (0.300", 7.62mm). PCB footprint and land pattern verification is required before implementation.
