PVT322AS-T Equivalent & Substitute Parts

Part Overview

The PVT322AS-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 250V at 170mA maximum load current, controlled by a 1.2VDC input signal.

The PVT322AS-T carries an Obsolete product status. Locating functionally equivalent alternatives is necessary for new designs, production continuity, and long-term component availability assurance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PVT322AS-T is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST-NO (1 Form A) x 2 channels
• Output type: AC and DC load switching capability
• Input voltage: 1.2VDC control signal
• Load voltage range: 0 V ~ 250 V
• Load current rating: 170 mA maximum
• On-state resistance: 8 Ohms maximum
• Package type: 8-SMD (0.300", 7.62mm) with Gull Wing termination
• Mounting: Surface mount technology
• Moisture sensitivity: MSL 4 (72 Hours)

The PVT322AS-TPBF meets all these criteria and qualifies as a direct substitute. The primary distinction is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The PVT322AS-TPBF is the direct functional equivalent of the PVT322AS-T. Both components share identical electrical and mechanical specifications across all critical parameters.

Selection between these parts should be based on:

• Product status: The PVT322AS-TPBF maintains Active status, ensuring ongoing availability and manufacturer support, whereas the PVT322AS-T is Obsolete.
• Regulatory compliance: The PVT322AS-TPBF is ROHS3 compliant, meeting current environmental regulations. The PVT322AS-T is RoHS non-compliant.
• Packaging requirements: The PVT322AS-TPBF is supplied in Tape & Reel format, suitable for automated assembly processes. The PVT322AS-T is supplied in bulk packaging.

For new designs and production applications, the PVT322AS-TPBF is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can PVT322AS-TPBF replace PVT322AS-T in existing designs?

A: Yes. The PVT322AS-TPBF is electrically and mechanically identical to the PVT322AS-T. Both components feature the same circuit configuration (SPST-NO x 2), input voltage (1.2VDC), load voltage range (0-250V), load current rating (170mA), on-state resistance (8 Ohms maximum), and 8-SMD package with Gull Wing termination. Direct substitution is valid.

Q: What is the difference between PVT322AS-T and PVT322AS-TPBF?

A: The electrical and mechanical specifications are identical. The differences are: (1) Product status—PVT322AS-T is Obsolete while PVT322AS-TPBF is Active; (2) Packaging format—PVT322AS-T is supplied in bulk, PVT322AS-TPBF in Tape & Reel; (3) RoHS compliance—PVT322AS-T is non-compliant, PVT322AS-TPBF is ROHS3 compliant.

Q: Are there any PCB layout or assembly considerations when switching from PVT322AS-T to PVT322AS-TPBF?

A: No. Both parts use identical 8-SMD (0.300", 7.62mm) packages with Gull Wing termination. PCB footprints, land patterns, and assembly processes remain unchanged.

Q: What is the Moisture Sensitivity Level (MSL) for these components?

A: Both the PVT322AS-T and PVT322AS-TPBF have MSL 4 (72 Hours). This indicates the component must be stored in controlled humidity conditions and has a 72-hour floor life after exposure to ambient conditions above the specified moisture threshold.

Q: Is the PVT322AS-T still available for purchase?

A: The PVT322AS-T is classified as Obsolete. While limited inventory may exist through component distributors, long-term availability is not assured. The PVT322AS-TPBF, with Active status, is the recommended alternative for current and future procurement.
