Substitute Part Grouping Explanation
Substitution eligibility for the PVU414S is determined by the following critical parameters:
Primary Matching Criteria:
- Circuit configuration: SPST-NO (1 Form A)
- Output type: AC, DC
- Package / Case: 6-SMD (0.300", 7.62mm)
- Mounting type: Surface Mount
- Termination style: Gull Wing
Performance Compatibility Criteria:
- Load voltage range: Must support 0–400 V minimum
- Load current: Must support 140 mA minimum
- Input voltage: 1.14–1.2 VDC acceptable range
- On-state resistance: Lower values preferred for thermal performance
Substitute parts are grouped into two categories based on these parameters: direct equivalents maintaining identical electrical specifications, and functional alternatives with comparable or superior performance characteristics within the same package footprint.

Engineering Selection Recommendations
Direct Equivalent (Recommended Primary Substitute):
PVU414SPBF is the direct functional equivalent to PVU414S, maintaining identical electrical specifications (140 mA load current, 0–400 V load voltage, 27 Ohms on-state resistance) and package configuration. This part is manufactured by Infineon Technologies and carries Active product status with ROHS3 compliance, addressing the obsolescence and regulatory compliance limitations of the original PVU414S.
Alternative Substitutes (Load Voltage 0–400 V):
AQV214EHA, AQV214EAZ, and AQV214EHAX (Panasonic Electric Works PhotoMOS™ AQV series) support the full 0–400 V load voltage range required by the original specification. These parts feature 120 mA load current (14% reduction from PVU414S) and 50 Ohms on-state resistance. All three variants are Active status with ROHS3 compliance. Selection between tube (EHA) and tape & reel (EAZ, EHAX) packaging depends on procurement and assembly requirements.
Conditional Substitutes (Load Voltage 0–350 V):
AQV210EA, AQV210EAZ, AQV210EHA, and AQV210EHAZ (Panasonic Electric Works PhotoMOS™ AQV series) are suitable only for applications where maximum load voltage does not exceed 350 V. These parts deliver 130 mA load current and 35 Ohms on-state resistance, providing superior thermal performance compared to AQV214 variants. All are Active status with RoHS compliance. Packaging options include tube (EA, EHA) and tape & reel (EAZ, EHAZ) configurations.
Frequently Asked Questions (FAQ)
Q: Can PVU414SPBF directly replace PVU414S without circuit modification?
A: Yes. PVU414SPBF is electrically and mechanically identical to PVU414S, with matching load voltage (0–400 V), load current (140 mA), input voltage (1.2 VDC), on-state resistance (27 Ohms), and 6-SMD package footprint. The primary difference is product status (Active vs. Obsolete) and RoHS compliance (ROHS3 vs. non-compliant).
Q: What is the impact of selecting AQV214 series over PVU414SPBF?
A: AQV214 variants maintain 0–400 V load voltage compatibility but reduce load current from 140 mA to 120 mA (14% reduction). On-state resistance increases from 27 Ohms to 50 Ohms. These changes are acceptable only if the application load current does not exceed 120 mA and thermal dissipation margins accommodate the higher resistance.
Q: Are AQV210 series parts suitable for this application?
A: AQV210 series parts are suitable only if the application maximum load voltage is 350 V or lower. These parts offer superior on-state resistance (35 Ohms) and load current (130 mA) compared to AQV214 variants, but the reduced voltage rating makes them incompatible with designs requiring the full 0–400 V range of the original PVU414S.
Q: What packaging options are available for substitute parts?
A: Infineon PVU414SPBF is supplied in Tube packaging. Panasonic AQV series substitutes are available in two packaging formats: Tube (EA, EHA variants) for manual assembly and small-volume applications, and Tape & Reel (EAZ, EHAZ, EHAX variants) for automated pick-and-place assembly and high-volume production.
Q: Do all substitute parts meet current RoHS compliance requirements?
A: PVU414SPBF and all Panasonic AQV series substitutes are RoHS compliant (ROHS3 or RoHS Compliant status). The original PVU414S is RoHS non-compliant, making any of these substitutes suitable for designs requiring regulatory compliance.
Q: What is the input voltage tolerance across substitute options?
A: The original PVU414S operates at 1.2 VDC input. Panasonic AQV series substitutes operate at 1.14 VDC input. Both voltage levels are within acceptable control circuit tolerances for standard SSR driver circuits, with no additional design modifications required.
