PVA2352 Solid State Relay SPST-NO — Equivalent & Substitute Parts

Part Overview

The PVA2352 is a Solid State Relay (SSR) manufactured by Infineon Technologies, configured as a Single Pole Single Throw Normally Open (SPST-NO) switch in an 8-DIP through-hole package. This component is rated for 130 mA load current at 0–200 V AC/DC output with 1.2 VDC input control voltage. The PVA2352 is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PVA2352 is determined by the following critical parameters:

• Circuit Configuration: Must remain SPST-NO (1 Form A) to maintain identical switching topology
• Package / Case: Must be 8-DIP (0.300", 7.62mm), 4 Leads to ensure PCB compatibility without layout redesign
• Mounting Type: Must be Through Hole to match existing board assembly methods
• Input Voltage: Must be 1.2 VDC to maintain control signal compatibility
• Output Type: Must support AC and DC switching
• Load Current Rating: Substitute must meet or exceed 130 mA requirement
• Load Voltage Range: Substitute must cover or exceed 0–200 V range
• On-State Resistance: Must not exceed 24 Ohms to maintain thermal and power dissipation characteristics

The PVA3354NPBF meets all substitution criteria while offering enhanced electrical performance and active product status.

Parameter Comparison

Engineering Selection Recommendations

The PVA3354NPBF is the direct substitute for the obsolete PVA2352. This substitution is supported by:

• Identical mechanical and electrical interface: Same 8-DIP package, pin configuration, and PC pin termination enable direct board-level replacement without layout modification
• Enhanced electrical performance: The PVA3354NPBF provides 150 mA load current capacity and 0–300 V load voltage range, both exceeding the PVA2352 specifications, ensuring compatibility with existing circuit requirements and providing design margin
• Active product status: The PVA3354NPBF is an active Infineon product with ongoing manufacturing and supply chain support, eliminating obsolescence risk
• Regulatory compliance: The PVA3354NPBF meets ROHS3 compliance requirements, whereas the PVA2352 is RoHS non-compliant, making the substitute suitable for applications subject to environmental regulations

Frequently Asked Questions (FAQ)

Q: Can the PVA3354NPBF be used as a direct replacement for the PVA2352 without PCB modifications?

A: Yes. Both parts share identical package geometry (8-DIP, 0.300" spacing), pin count (4 leads), and termination style (PC pin). No PCB layout changes are required for substitution.

Q: What are the key electrical differences between the PVA2352 and PVA3354NPBF?

A: The PVA3354NPBF provides higher load current capacity (150 mA vs. 130 mA) and extended load voltage range (0–300 V vs. 0–200 V). On-state resistance remains identical at 24 Ohms maximum. Input control voltage is unchanged at 1.2 VDC.

Q: Why is the PVA2352 classified as obsolete?

A: The PVA2352 has been discontinued by Infineon Technologies. The PVA3354NPBF represents the current active product offering within the PVA solid state relay family.

Q: Are there any compliance or certification differences?

A: Yes. The PVA2352 is RoHS non-compliant, while the PVA3354NPBF meets ROHS3 compliance standards. Both parts are REACH Unaffected and classified under ECCN EAR99.

Q: Will the PVA3354NPBF function identically in my existing circuit?

A: The PVA3354NPBF maintains identical input control voltage (1.2 VDC), circuit configuration (SPST-NO), and on-state resistance (24 Ohms). The higher current and voltage ratings do not affect circuit operation and provide additional design margin.

Q: What is the packaging difference between the two parts?

A: The PVA2352 is supplied in standard packaging, while the PVA3354NPBF is supplied in Tube packaging. Both use identical 8-DIP component packages suitable for through-hole PCB assembly.
