PVT322S-T Equivalent & Substitute Parts

Part Overview

The PVT322S-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 requiring AC or DC loads up to 250V at 170mA with a control input of 1.2VDC. The part is currently classified as obsolete, making identification of equivalent and substitute components essential for ongoing production support and design continuity.

Substitute Part Grouping Explanation

Substitution of the PVT322S-T is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPST-NO (1 Form A) x 2 channels
• Voltage Ratings: Input 1.2VDC, Load 0–250V AC/DC
• Load Current: 170 mA maximum
• On-State Resistance: 10 Ohms maximum
• Package Type: 8-SMD (0.300", 7.62mm) with Gull Wing termination
• Mounting: Surface Mount

The substitute part PVT322S-TPBF maintains identical electrical specifications and mechanical packaging, ensuring direct functional replacement without circuit redesign or PCB layout modification.

Parameter Comparison

Engineering Selection Recommendations

The PVT322S-TPBF is a direct functional equivalent to the PVT322S-T. The primary distinction is product status: the original part is obsolete while the substitute maintains active production status through International Rectifier. Both components share identical electrical performance specifications and mechanical packaging, permitting direct substitution in existing designs without modification to PCB layouts or control circuitry.

Selection of the PVT322S-TPBF is appropriate for new production builds, design refreshes, and long-term supply chain continuity where the PVT322S-T is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the PVT322S-TPBF replace the PVT322S-T in existing designs?

A: Yes. The PVT322S-TPBF is electrically and mechanically identical to the PVT322S-T. No circuit modifications or PCB layout changes are required for substitution.

Q: Are there differences in RoHS or REACH compliance between these parts?

A: The PVT322S-T is RoHS non-compliant. Compliance information for the PVT322S-TPBF should be verified against the specific supplier datasheet, as compliance status may differ between manufacturers.

Q: What is the significance of the "-TPBF" suffix in the part number?

A: The "-TPBF" suffix typically indicates a lead-free or RoHS-compliant variant. Consult the manufacturer datasheet for specific material and processing specifications.

Q: Are both parts suitable for AC and DC load switching?

A: Yes. Both the PVT322S-T and PVT322S-TPBF support AC and DC output switching at loads up to 250V and 170mA.

Q: What is the moisture sensitivity level for these components?

A: The PVT322S-T has an MSL rating of 4 (72 Hours). Confirm MSL specifications for the PVT322S-TPBF with the supplier, as this may vary.

Q: Can these relays be used in high-frequency switching applications?

A: Switching frequency capability is not provided in the specified parameters. Consult detailed datasheets for frequency-dependent performance characteristics.
