PVI5033R Equivalent & Substitute Parts

Part Overview

The PVI5033R is a photovoltaic output optoisolator manufactured by Infineon Technologies, designed for 3750Vrms isolation in 2-channel configurations. This component operates with DC input and photovoltaic output, providing galvanic isolation in high-voltage applications. The PVI5033R is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Substitute components must maintain compatibility across isolation voltage, channel count, package type, and output characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PVI5033R is determined by the following critical parameters:

• Isolation Voltage: Minimum 3750Vrms required for functional equivalence
• Number of Channels: Must be 2 channels
• Output Type: Photovoltaic output required
• Input Type: DC input required
• Package Type: 8-DIP (0.300", 7.62mm) through-hole mounting
• Operating Temperature Range: -40°C to 85°C minimum

The substitute parts listed below meet these core requirements while maintaining electrical and mechanical compatibility with the original PVI5033R specification.

Parameter Comparison

Engineering Selection Recommendations

PVI5033RPBF (Infineon Technologies): Direct manufacturer equivalent with identical electrical specifications to the PVI5033R. This part maintains the same isolation voltage (3750Vrms), output voltage (10V maximum), and output current (5µA per channel). The primary distinction is product status—PVI5033RPBF is active and ROHS3 compliant, whereas the original PVI5033R is obsolete and non-compliant. Packaging is identical (8-DIP tube). This substitute is the preferred choice for direct replacement in existing designs.

ASSR-V621-002E (Broadcom Limited): Meets core substitution criteria with 3750Vrms isolation and 2-channel photovoltaic output in 8-DIP package. Electrical characteristics differ in output voltage (7V maximum versus 10V) and output current (20µA per channel versus 5µA). Forward current specification is lower (30 mA maximum versus 40 mA). Switching times are significantly faster (280µs turn-on, 30µs turn-off versus 2.5ms, 500µs). ROHS3 compliant and active product status.

LH1262CB (Vishay Semiconductor Opto Division): Exceeds isolation voltage requirement at 5300Vrms, providing enhanced isolation margin. Maintains 2-channel photovoltaic output in 8-DIP package. Output voltage is higher (15V maximum versus 10V), and output current is lower (1µA per channel versus 5µA). Switching times are faster (35µs turn-on, 90µs turn-off). Forward current specification is higher (50 mA maximum versus 40 mA). ROHS3 compliant and active product status.

Selection between active substitutes depends on application requirements for output voltage, output current, and switching speed. All three substitutes maintain through-hole 8-DIP package compatibility and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can PVI5033RPBF directly replace PVI5033R in existing circuit boards?

A: Yes. PVI5033RPBF is the direct manufacturer equivalent with identical electrical specifications, isolation voltage (3750Vrms), channel count (2), output type (photovoltaic), and 8-DIP package dimensions. The primary difference is product status and RoHS compliance. No circuit modifications are required.

Q: What are the key differences between PVI5033RPBF and ASSR-V621-002E?

A: Both maintain 3750Vrms isolation and 2-channel photovoltaic output in 8-DIP packages. ASSR-V621-002E has lower maximum output voltage (7V versus 10V) and higher output current per channel (20µA versus 5µA). Switching times are significantly faster with ASSR-V621-002E (280µs turn-on versus 2.5ms). Forward current is lower (30 mA versus 40 mA). Application requirements for output voltage and switching speed determine suitability.

Q: Why does LH1262CB have higher isolation voltage than the original specification?

A: LH1262CB provides 5300Vrms isolation compared to the 3750Vrms requirement. This exceeds the minimum specification and provides additional isolation margin. All other critical parameters—channel count, output type, package, and operating temperature—remain compatible. Higher isolation voltage does not prevent substitution in applications designed for 3750Vrms.

Q: Are all substitute parts RoHS compliant?

A: Yes. PVI5033RPBF, ASSR-V621-002E, and LH1262CB are all ROHS3 compliant. The original PVI5033R is RoHS non-compliant. Compliance status is relevant for new designs and applications subject to RoHS regulations.

Q: Do all substitutes use the same 8-DIP package?

A: Yes. All substitute parts use 8-DIP (0.300", 7.62mm) through-hole packages, maintaining mechanical compatibility with existing PCB layouts designed for PVI5033R.

Q: Which substitute has the fastest switching response?

A: LH1262CB has the fastest switching times with 35µs turn-on and 90µs turn-off. ASSR-V621-002E is also faster than the original (280µs turn-on, 30µs turn-off) compared to PVI5033R and PVI5033RPBF (2.5ms turn-on, 500µs turn-off maximum).
