PVT422S-T Equivalent & Substitute Parts

Part Overview

The PVT422S-T is a solid-state relay (SSR) manufactured by Infineon Technologies, configured as a SPST-NO (Single Pole Single Throw - Normally Open) relay with dual channels in an 8-SMD surface mount package. This component is designed for switching applications with AC and DC loads up to 400V at 120mA maximum load current. The PVT422S-T is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PVT422S-T are qualified based on the following critical parameters that determine functional compatibility:

• Circuit configuration: SPST-NO (1 Form A) x 2 channels
• Load voltage range: 0 V ~ 400 V
• Package type: 8-SMD (0.300", 7.62mm) with Gull Wing termination
• Mounting method: Surface Mount
• Output capability: AC and DC switching
• On-state resistance: Maximum 35 Ohms

Substitutes must maintain these electrical and mechanical specifications to ensure direct replacement capability in existing PCB designs without layout modifications.

Engineering Selection Recommendations

PVT422S-TPBF is the direct equivalent to PVT422S-T from Infineon Technologies. This part maintains identical electrical specifications and package configuration while offering active product status and ROHS3 compliance. The PVT422S-TPBF differs only in packaging format (Cut Tape & Digi-Reel versus standard packaging) and regulatory compliance status, making it the primary replacement for obsolete PVT422S-T inventory.

AQW214EHAZ from Panasonic Electric Works is a qualified cross-manufacturer substitute. This part meets all critical electrical and mechanical compatibility requirements with the following considerations: load current rating is 100mA versus 120mA on the PVT422S-T, input voltage is 1.14VDC versus 1.2VDC, and moisture sensitivity is not applicable (indicating different packaging or material composition). The AQW214EHAZ offers active product status and RoHS compliance. Selection of this substitute requires verification that the 100mA load current maximum is sufficient for the intended application.

Frequently Asked Questions (FAQ)

Q: Can PVT422S-TPBF be used as a direct replacement for PVT422S-T?

A: Yes. PVT422S-TPBF is the direct equivalent from Infineon Technologies with identical electrical specifications, circuit configuration, and package dimensions. The primary difference is product status (active versus obsolete) and RoHS compliance level.

Q: What is the key limitation when substituting AQW214EHAZ for PVT422S-T?

A: The AQW214EHAZ has a maximum load current rating of 100mA compared to 120mA for PVT422S-T. Applications requiring load currents between 100mA and 120mA must be evaluated to confirm the lower rating is acceptable.

Q: Are all three parts pin-compatible?

A: Yes. All three parts share the same 8-SMD (0.300", 7.62mm) package with Gull Wing termination, enabling direct PCB footprint compatibility without layout modifications.

Q: What is the difference between PVT422S-T and PVT422S-TPBF packaging?

A: PVT422S-T uses standard packaging, while PVT422S-TPBF is supplied in Cut Tape (CT) & Digi-Reel format. Both parts are identical in electrical performance and physical dimensions.

Q: Does AQW214EHAZ have moisture sensitivity requirements?

A: AQW214EHAZ is listed as Not Applicable for Moisture Sensitivity Level, indicating it does not require the same moisture control handling as PVT422S-T (MSL 4, 72 Hours) or PVT422S-TPBF (MSL 4, 72 Hours).

Q: Which substitute should be selected for new designs?

A: Selection depends on manufacturer preference and supply chain strategy. PVT422S-TPBF maintains Infineon continuity with full compliance. AQW214EHAZ provides cross-manufacturer diversity with active status, subject to load current verification.
