PVT212S Equivalent & Substitute Parts

Part Overview

The PVT212S is a solid-state relay (SSR) manufactured by Infineon Technologies, configured as a SPST-NO (Single Pole Single Throw - Normally Open) switch with 550 mA load capacity and 0–150 V output voltage range. This component operates on 1.2 VDC input and features a 6-SMD surface mount package with 750 mOhms maximum on-state resistance.

The PVT212S is classified as obsolete. Locating equivalent or substitute parts is necessary to support ongoing production, maintenance, or redesign requirements for systems currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the PVT212S is determined by the following critical parameters:

• Circuit Configuration: SPST-NO topology (1 Form A switch)
• Output Type: AC and DC switching capability
• Load Voltage Range: 0–150 V maximum
• Load Current: 550 mA maximum
• Input Voltage: 1.2 VDC trigger level
• Package Compatibility: 6-SMD surface mount form factor
• On-State Resistance: 750 mOhms maximum

Two substitute parts are identified:

1. PVT212SPBF (Infineon Technologies) — Direct manufacturer equivalent with identical electrical and mechanical specifications. Primary difference: active product status and RoHS3 compliance.

2. AQY221N3M (Panasonic Electric Works) — Cross-manufacturer substitute with reduced electrical ratings (150 mA load current, 0–25 V load voltage, 7.5 Ohms on-state resistance) and different package format (4-SMD). This part operates within a constrained parameter envelope and is suitable only for applications with lower current and voltage requirements.

Parameter Comparison

Engineering Selection Recommendations

PVT212SPBF is the primary substitute for PVT212S. Both parts are manufactured by Infineon Technologies and share identical electrical ratings (550 mA, 0–150 V, 750 mOhms) and mechanical packaging (6-SMD, Gull Wing termination). PVT212SPBF is currently in active production status and meets RoHS3 compliance requirements, addressing regulatory and supply chain concerns associated with the obsolete PVT212S. Direct PCB layout and circuit compatibility is maintained.

AQY221N3M is a cross-manufacturer alternative suitable only for applications with reduced electrical requirements. This Panasonic PhotoMOS™ component operates at 150 mA maximum load current and 0–25 V load voltage—both significantly lower than the PVT212S specification envelope. The 4-SMD package format differs from the 6-SMD footprint of the original part, requiring PCB redesign. On-state resistance of 7.5 Ohms is substantially higher than the 750 mOhms specification. Selection of AQY221N3M requires verification that application load parameters fall within its reduced rating envelope.

Frequently Asked Questions (FAQ)

Q: Can PVT212SPBF be used as a direct drop-in replacement for PVT212S?

A: Yes. PVT212SPBF is electrically and mechanically identical to PVT212S. Both components feature the same 6-SMD package footprint, Gull Wing termination, 550 mA load current rating, 0–150 V load voltage range, and 750 mOhms on-state resistance. PCB layout and circuit connections require no modification.

Q: What are the limitations of AQY221N3M as a substitute?

A: AQY221N3M operates within a constrained electrical envelope: maximum 150 mA load current (versus 550 mA) and maximum 0–25 V load voltage (versus 0–150 V). On-state resistance is 7.5 Ohms, approximately 10 times higher than PVT212S. The 4-SMD package footprint differs from the 6-SMD format, requiring PCB redesign. AQY221N3M is suitable only for low-current, low-voltage switching applications.

Q: Are there package compatibility concerns when substituting these parts?

A: PVT212SPBF maintains full package compatibility with PVT212S (both 6-SMD, 0.300" × 7.62mm, Gull Wing). AQY221N3M uses a different 4-SMD package (0.116" × 2.95mm) with SMD Tab termination, requiring PCB layout modification and cannot be used as a direct footprint replacement.

Q: What is the compliance status difference between PVT212S and PVT212SPBF?

A: PVT212S is RoHS non-compliant. PVT212SPBF is RoHS3 compliant. Both parts carry identical Moisture Sensitivity Level (MSL) rating of 4 (72 Hours). For applications subject to RoHS regulatory requirements, PVT212SPBF is the appropriate selection.

Q: Can AQY221N3M handle the full 550 mA and 150 V specifications of the original PVT212S?

A: No. AQY221N3M is rated for maximum 150 mA load current and 0–25 V load voltage. Operating this component at PVT212S specification levels (550 mA, 0–150 V) will exceed its electrical ratings and cause component failure.
