PVN012S Solid State Relay - Equivalent & Substitute Parts

Part Overview

The PVN012S is a Surface Mount Solid State Relay (SSR) manufactured by Infineon Technologies, configured as a SPST-NO (Single Pole Single Throw - Normally Open) relay with a 1 Form A circuit. This component is rated for 2.5A load current across 0-20V DC/AC output with a 1.2VDC input trigger voltage. The part is classified as Obsolete, necessitating identification of functionally equivalent alternatives for ongoing production and maintenance applications. Substitute parts must maintain electrical compatibility across input voltage, load voltage range, load current capacity, and output switching characteristics while accommodating modern packaging and compliance requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the PVN012S is determined by strict electrical and mechanical parameter alignment:

Primary Substitution Criteria:

• Circuit configuration must remain SPST-NO (1 Form A)
• Output type must support both AC and DC switching
• Input voltage tolerance must accommodate 1.2VDC nominal operation
• Load voltage range must encompass 0-20V
• Load current capacity must meet or exceed 2.5A requirement
• Surface Mount mounting type must be maintained
• Package footprint compatibility with 6-SMD (0.300", 7.62mm) or equivalent land pattern

Substitute Classification:

Direct Equivalent (Active Status): PVN012SPBF maintains identical electrical specifications and 6-SMD package footprint with Gull Wing termination. This part represents the direct production replacement with active product status and improved RoHS3 compliance.

Functional Alternatives (Reduced Current Rating): TLP3231(TP15,F) and TLP3431(TP,F) are Toshiba Semiconductor SSR relays with matching circuit configuration, input/output voltage parameters, and Surface Mount technology. These parts operate within the specified load voltage range (0-20V) and input voltage window (1.15VDC and 1.27VDC respectively). However, both alternatives are rated for 450mA maximum load current, representing a 82% reduction from the PVN012S 2.5A specification. These parts are suitable only for applications where actual load current does not exceed 450mA.

Engineering Selection Recommendations

For Direct Replacement (Recommended Primary Choice):

PVN012SPBF is the optimal substitute when full electrical specification matching is required. This part maintains identical load current capacity (2.5A), on-state resistance (100 mOhms), package footprint (6-SMD 0.300"), and termination style (Gull Wing). The transition from Obsolete to Active product status ensures long-term supply availability. ROHS3 compliance provides regulatory advantage over the non-compliant PVN012S. Moisture Sensitivity Level remains at MSL 4 (72 Hours), matching the original specification. No circuit redesign or PCB layout modification is necessary.

For Current-Limited Applications:

TLP3231(TP15,F) and TLP3431(TP,F) are viable substitutes exclusively for applications where maximum load current does not exceed 450mA. Both parts maintain the required SPST-NO circuit configuration, AC/DC output capability, and 0-20V load voltage range. Input voltage specifications (1.15VDC and 1.27VDC) remain compatible with 1.2VDC nominal operation. Both alternatives offer improved RoHS compliance (RoHS Compliant or ROHS3 Compliant) and superior moisture handling (MSL 3, 168 Hours). Package footprint changes (4-SMD configurations) and termination style modifications (SMD Tab vs. Gull Wing) require PCB layout redesign and revalidation. On-state resistance increases to 1.2 Ohms, resulting in higher power dissipation compared to the 100 mOhms specification.

Compliance Considerations:

All substitute parts maintain REACH Unaffected status and EAR99 ECCN classification matching the original PVN012S. HTSUS code 8536.41.0030 remains consistent across all alternatives.

Frequently Asked Questions (FAQ)

Q: Can PVN012SPBF be used as a direct drop-in replacement for PVN012S?

A: Yes. PVN012SPBF is electrically and mechanically identical to PVN012S with matching 6-SMD (0.300", 7.62mm) Gull Wing package, 2.5A load current rating, 100 mOhms on-state resistance, and 1.2VDC input voltage. No circuit or PCB modifications are required. The primary advantage is Active product status versus Obsolete classification.

Q: What is the key limitation of TLP3231(TP15,F) and TLP3431(TP,F) as substitutes?

A: Both Toshiba alternatives are rated for maximum 450mA load current, compared to the PVN012S 2.5A specification. These parts are suitable only for applications where actual load current remains below 450mA. Applications requiring the full 2.5A capacity must use PVN012SPBF.

Q: Do the Toshiba alternatives require PCB layout changes?

A: Yes. TLP3231(TP15,F) uses 4-SMD Flat Leads package, and TLP3431(TP,F) uses 4-SMD (0.096", 2.45mm) package, both differing from the original 6-SMD (0.300", 7.62mm) footprint. Termination style changes from Gull Wing to SMD Tab. PCB land pattern redesign and revalidation are necessary.

Q: Are all substitute parts RoHS compliant?

A: PVN012S is RoHS non-compliant. PVN012SPBF is ROHS3 Compliant. TLP3231(TP15,F) is RoHS Compliant. TLP3431(TP,F) is ROHS3 Compliant. All substitutes offer improved compliance status.

Q: How do on-state resistance differences affect circuit performance?

A: PVN012S and PVN012SPBF both specify 100 mOhms maximum on-state resistance. TLP3231(TP15,F) and TLP3431(TP,F) specify 1.2 Ohms, representing a 12x increase. At 450mA load current, this results in 0.54W power dissipation in the Toshiba parts versus 0.02W in the Infineon parts. Thermal management and power budget analysis are required when using Toshiba alternatives.

Q: What is the input voltage tolerance for each part?

A: PVN012S and PVN012SPBF require 1.2VDC nominal input. TLP3231(TP15,F) operates at 1.15VDC nominal. TLP3431(TP,F) operates at 1.27VDC nominal. All three input voltages fall within typical logic-level signal ranges and are compatible with standard 3.3V or 5V microcontroller outputs through appropriate current-limiting resistors.
