PVG612 Solid State Relay SPST-NO Equivalent & Substitute Parts
Part Overview
The PVG612 is a solid state relay (SSR) manufactured by Infineon Technologies, configured as a SPST-NO (Single Pole Single Throw - Normally Open) relay in a 6-DIP through-hole package. This component operates with a 1.2VDC input signal and switches loads up to 1A across 0-60V AC or DC output. The PVG612 is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production support. Active alternatives from Panasonic Electric Works and IXYS Integrated Circuits Division provide direct functional replacement with enhanced compliance certifications.

Substitute Part Grouping Explanation
Substitution eligibility for the PVG612 is determined by the following critical parameters:
Package Compatibility: All substitute parts must use the 6-DIP (0.300", 7.62mm) through-hole package with PC pin termination to ensure direct PCB compatibility without layout modifications.
Circuit Configuration: All substitutes maintain SPST-NO (1 Form A) configuration, preserving the single-channel normally-open switching topology.
Output Type: Substitutes must support both AC and DC output switching to maintain functional equivalence across application types.
Voltage Rating - Load: The PVG612 operates across 0-60V. Substitutes with 0-60V ratings provide full compatibility. Parts rated 0-40V are limited substitutes suitable only for applications not exceeding 40V load voltage.
Load Current: The PVG612 handles 1A maximum. Substitutes with 1A or higher current ratings provide full compatibility. Parts with lower current ratings (700mA, 550mA, 500mA, 400mA, 600mA) are limited substitutes suitable only for applications not exceeding their specified current limits.
Input Voltage: The PVG612 requires 1.2VDC input. Substitutes with 1.2VDC or lower input voltage requirements provide full compatibility. Parts with higher input voltage requirements (2.3VDC) require circuit modification and are not direct substitutes.
On-State Resistance: The PVG612 specifies 500 mOhms maximum. Substitutes with equal or lower on-state resistance maintain electrical performance. Higher resistance values indicate reduced switching efficiency.
Product Status & Compliance: Active parts with RoHS3 compliance are preferred for new designs. The PVG612's obsolete status and RoHS non-compliance status necessitate migration to active alternatives.

Engineering Selection Recommendations
Direct Replacement (Full Compatibility):
PVG612PBF, LCA710, and LCA712 provide complete electrical and mechanical equivalence to the PVG612. All three maintain 1.2VDC input voltage, 0-60V load voltage range, 1A load current, and 500 mOhms on-state resistance. These parts are active products with RoHS3 compliance, making them suitable for new designs and production transitions. PVG612PBF is the direct Infineon equivalent with identical specifications and active status. LCA710 and LCA712 from IXYS provide functionally identical performance with OptoMOS® technology.
Limited Substitutes (Application-Dependent):
PLA132 operates at 1.2VDC input and 0-60V load voltage but is limited to 600mA load current. This part is suitable for applications where load current does not exceed 600mA.
AQV212 and AQV252 operate at 1.14VDC input (compatible with 1.2VDC circuits) and 0-60V load voltage but are limited to 550mA and 400mA respectively. These parts are suitable only for applications within their current specifications.
AQV251 operates at 1.14VDC input and 0-40V load voltage, limited to 500mA. This part is suitable only for applications not exceeding 40V load voltage and 500mA current.
Not Recommended:
AQV201 and AQV202 require 2.3VDC input voltage, necessitating circuit modification and are not direct substitutes without design changes.
AQV101 supports only DC output (not AC/DC), limiting its application scope and is not a full functional equivalent.
All substitute parts maintain the 6-DIP through-hole package and PC pin termination, ensuring PCB compatibility without layout modifications.
Frequently Asked Questions (FAQ)
Q: Can PVG612PBF be used as a direct replacement for PVG612?
A: Yes. PVG612PBF is the active equivalent from Infineon Technologies with identical electrical specifications (1.2VDC input, 0-60V load voltage, 1A load current, 500 mOhms on-state resistance) and the same 6-DIP package. The primary difference is product status (active vs. obsolete) and RoHS3 compliance.
Q: What is the difference between LCA710, LCA712, and PVG612PBF?
A: All three parts are electrically identical with 1.2VDC input, 0-60V load voltage, 1A load current, and 500 mOhms on-state resistance. LCA710 and LCA712 are IXYS OptoMOS® technology, while PVG612PBF is Infineon HEXFET® technology. All are active products with RoHS3 compliance and the same 6-DIP package.
Q: Can AQV212 replace PVG612 in all applications?
A: AQV212 is a limited substitute. It maintains 1.14VDC input voltage (compatible with 1.2VDC circuits) and 0-60V load voltage range, but is limited to 550mA load current. It is suitable only for applications where load current does not exceed 550mA. The on-state resistance is higher at 2.5 Ohms compared to PVG612's 500 mOhms.
Q: Why do some substitutes require 2.3VDC input instead of 1.2VDC?
A: AQV201 and AQV202 are designed with higher input voltage thresholds (2.3VDC). These parts are not direct substitutes for PVG612 without circuit modification to the input signal conditioning. Direct substitutes maintain the 1.2VDC input requirement.
Q: What does "0-60V load voltage range" mean?
A: This specifies the maximum voltage the relay can switch across its output terminals. The PVG612 and its full equivalents can safely switch loads from 0V to 60V. Substitutes rated 0-40V are limited to applications not exceeding 40V load voltage.
Q: Are all substitute parts available in the same package?
A: Yes. All listed substitute parts use the 6-DIP (0.300", 7.62mm) through-hole package with PC pin termination, ensuring direct PCB compatibility without layout modifications.
Q: What is the significance of RoHS3 compliance?
A: RoHS3 compliance indicates the part meets current environmental and hazardous substance restrictions. The PVG612 is RoHS non-compliant (obsolete standard). Active substitutes with RoHS3 compliance are required for new designs and production in regulated markets.
Q: Can PLA132 be used if my application only requires 600mA?
A: Yes. PLA132 is suitable for applications requiring 600mA or less at 0-60V load voltage with 1.2VDC input. It maintains the same package and on-state resistance performance as PVG612 within its current rating.
Q: What is on-state resistance and why does it matter?
A: On-state resistance is the electrical resistance when the relay is conducting (switched on). Lower resistance reduces power dissipation and heat generation. PVG612 specifies 500 mOhms. Substitutes with higher resistance (1 Ohm, 1.4 Ohms, 2.5 Ohms) will generate more heat during operation and may require thermal management consideration in high-current applications.
