PVD2352N Equivalent & Substitute Parts

Part Overview

The PVD2352N is a solid-state relay (SSR) manufactured by Infineon Technologies, configured as a single-pole single-throw normally-open (SPST-NO) switch. This component operates with a 1.2VDC input signal and controls DC loads up to 200V at 240mA maximum current. The device is packaged in an 8-DIP through-hole configuration with 4 leads and features a maximum on-state resistance of 6 Ohms.

The PVD2352N is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PVD2352N is determined by the following critical parameters:

• Circuit Configuration: Must remain SPST-NO (1 Form A) to maintain switching topology
• Package / Case: Must be 8-DIP (0.300", 7.62mm), 4 Leads to ensure PCB compatibility and mounting
• Voltage - Input: Must be 1.2VDC to match control signal requirements
• Voltage - Load: Must support 0 V ~ 200 V range for load compatibility
• Termination Style: Must be PC Pin for through-hole PCB assembly

The PVA2352NPBF qualifies as a manufacturer-recommended substitute. While it operates at a reduced maximum load current (150mA versus 240mA) and exhibits higher on-state resistance (24 Ohms versus 6 Ohms), it maintains identical input voltage, load voltage range, package configuration, and circuit topology. The PVA2352NPBF additionally supports AC output operation, providing expanded application flexibility.

Engineering Selection Recommendations

The PVA2352NPBF is the manufacturer-recommended substitute for the obsolete PVD2352N. Selection of this substitute is supported by the following factors:

• Product Status: The PVA2352NPBF maintains active production status, ensuring long-term availability and supply chain continuity
• Compliance: The PVA2352NPBF achieves ROHS3 compliance, meeting current regulatory requirements for electronic components in regulated markets
• Functional Compatibility: Identical input voltage (1.2VDC), load voltage range (0 V ~ 200 V), circuit configuration (SPST-NO), and package form factor (8-DIP, 4 Leads) ensure direct PCB compatibility
• Enhanced Capability: The PVA2352NPBF supports both AC and DC output operation, providing design flexibility beyond the DC-only capability of the original part

Applications requiring the full 240mA load current of the PVD2352N must account for the reduced 150mA maximum current rating of the PVA2352NPBF. Similarly, circuits sensitive to on-state resistance must accommodate the increase from 6 Ohms to 24 Ohms.

Frequently Asked Questions (FAQ)

Q: Can the PVA2352NPBF be used as a direct replacement for the PVD2352N in existing designs?

A: The PVA2352NPBF is mechanically and electrically compatible with the PVD2352N for PCB assembly. However, the reduced load current rating (150mA versus 240mA) and increased on-state resistance (24 Ohms versus 6 Ohms) must be evaluated against circuit requirements. Applications operating at or near the 240mA limit require design review.

Q: What is the significance of the different output type specifications?

A: The PVD2352N is specified for DC output only, while the PVA2352NPBF supports both AC and DC output operation. This expanded capability in the substitute part does not restrict its use in DC-only applications.

Q: Are there any packaging differences between these parts?

A: Both parts use identical 8-DIP (0.300", 7.62mm) packaging with 4 leads and PC pin termination. The PVA2352NPBF is supplied in tube packaging, while the PVD2352N was supplied in standard packaging. This difference does not affect component functionality or PCB mounting.

Q: What compliance considerations apply to the substitute part?

A: The PVA2352NPBF is ROHS3 compliant, meeting current environmental and regulatory standards. The original PVD2352N is RoHS non-compliant. New designs and production runs should utilize the PVA2352NPBF to maintain regulatory compliance.

Q: How do the electrical performance differences affect circuit design?

A: The increased on-state resistance of the PVA2352NPBF (24 Ohms versus 6 Ohms) results in higher voltage drop across the relay during conduction. For a 150mA load, this produces a 3.6V drop compared to 0.9V in the original part. Circuit designs must account for this increased voltage drop in load calculations and power budget analysis.
