PVI1050NS-T Equivalent & Substitute Parts

Part Overview

The PVI1050NS-T is a 2-channel photovoltaic optoisolator manufactured by Infineon Technologies with 2500Vrms isolation voltage rating. This component is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. The part operates across the industrial temperature range of -40°C to 85°C and is packaged in 8-SMD surface mount configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the PVI1050NS-T is determined by the following critical parameters: 2-channel configuration, photovoltaic output type, surface mount packaging, and operating temperature range compatibility. The substitute parts are grouped into two categories based on packaging format and manufacturer recommendation status.

Direct Equivalent (Same Manufacturer): PVI1050NS-TPBF maintains identical electrical specifications and packaging as the main part, differing only in tape and reel packaging format and active product status with RoHS3 compliance.

Manufacturer-Recommended Alternatives (Broadcom Limited): The ASSR-V621 and ASSR-V622 series provide higher isolation voltage (3750Vrms), improved output current capability (20µA per channel), and faster switching characteristics. These parts are functionally compatible within applications where the enhanced isolation voltage and performance parameters are acceptable. The ASSR-V621 series uses 8-SMD packaging, while ASSR-V622 uses 8-DIP Gull Wing packaging. Both series are available in tube (302E) and tape & reel (502E) packaging formats.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Recommended for Existing Designs): PVI1050NS-TPBF is the primary substitute for PVI1050NS-T. This part maintains identical electrical and functional specifications while offering active product status and RoHS3 compliance. The only difference is packaging format (tape & reel versus bulk), making it suitable for production environments requiring compliant components.

For New Designs or Enhanced Performance Requirements: The Broadcom ASSR-V621 and ASSR-V622 series provide superior isolation voltage (3750Vrms versus 2500Vrms), higher output current capability (20µA versus 5µA per channel), and faster switching response. These parts are active products with RoHS3 compliance and improved moisture sensitivity ratings (MSL 1 versus MSL 4). Selection between ASSR-V621 and ASSR-V622 depends on package preference: ASSR-V621 for 8-SMD compatibility, ASSR-V622 for 8-DIP Gull Wing compatibility. Packaging format selection (tube 302E or tape & reel 502E) depends on procurement and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can PVI1050NS-TPBF be used as a direct replacement for PVI1050NS-T? A: Yes. PVI1050NS-TPBF is electrically and functionally identical to PVI1050NS-T. The difference is packaging format (tape & reel versus bulk) and product status (active versus obsolete). Both parts share the same 8-SMD, Gull Wing package footprint and electrical specifications.

Q: What are the key differences between PVI1050NS-T and the Broadcom ASSR-V621/V622 series? A: The Broadcom parts offer higher isolation voltage (3750Vrms versus 2500Vrms), increased output current per channel (20µA versus 5µA), and faster switching times (280µs/30µs versus 300µs/220µs). All parts maintain 2-channel photovoltaic output configuration and -40°C to 85°C operating temperature range.

Q: What is the difference between ASSR-V621 and ASSR-V622? A: Both series have identical electrical specifications. The difference is packaging: ASSR-V621 uses 8-SMD Gull Wing, while ASSR-V622 uses 8-DIP Gull Wing. Select based on PCB layout and assembly equipment compatibility.

Q: What does the 302E and 502E suffix indicate? A: The 302E suffix indicates tube packaging, while 502E indicates tape & reel packaging. Both contain identical parts; the difference is in the delivery format for manufacturing and assembly processes.

Q: Are all substitute parts RoHS3 compliant? A: Yes. PVI1050NS-TPBF and all Broadcom ASSR series parts are RoHS3 compliant. The original PVI1050NS-T is RoHS non-compliant, making the substitutes necessary for applications requiring regulatory compliance.

Q: What is the moisture sensitivity difference between these parts? A: PVI1050NS-T and PVI1050NS-TPBF have MSL 4 (72-hour limit), while all Broadcom ASSR parts have MSL 1 (unlimited storage). MSL 1 provides greater flexibility in storage and handling without baking requirements.
