PVT412 Solid State Relay SPST-NO Equivalent & Substitute Parts

Part Overview

The PVT412 is a solid state relay (SSR) manufactured by Infineon Technologies, featuring SPST-NO (Single Pole Single Throw - Normally Open) switching capability. This component is classified as obsolete, though 17,090 units remain in stock as new original inventory. The PVT412 operates with a 1.2VDC input signal and switches loads up to 400V at 140mA, with an on-state resistance of 27 Ohms maximum. Given its obsolete status, identifying functionally equivalent active alternatives is essential for new designs and long-term supply chain planning.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PVT412 are selected based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Circuit configuration: SPST-NO (1 Form A)
• Package type: 6-DIP (0.300", 7.62mm)
• Mounting type: Through Hole
• Load voltage range: 0V ~ 400V
• Load current capability: minimum 120mA (PVT412 operates at 140mA)
• Input voltage: 1.2VDC to 2.3VDC range
• On-state resistance: 8 to 50 Ohms

Substitution Categories:

Direct Equivalent (Same Manufacturer): PVT412PBF is the active production variant of PVT412, maintaining identical electrical specifications and package configuration. This represents the primary replacement path for obsolete PVT412 units.

Manufacturer-Recommended Alternatives: AQV104, AQV204, AQV214EH (Panasonic PhotoMOS™ series), ASSR-4111-001E (Broadcom ASSR series), and LCA100 (IXYS OptoMOS® series) are all active components meeting the core substitution parameters. These parts maintain 6-DIP packaging, SPST-NO configuration, and 0-400V load voltage capability.

Functional Alternatives with Parameter Variations: XCA170 (IXYS OptoMOS®) operates at reduced load voltage (0-350V) and current (100mA), suitable only for applications not requiring the full 400V or 140mA capability. LH1502BB (Vishay) provides dual-circuit functionality (SPST-NO + SPST-NC) in an 8-DIP package, requiring PCB layout modification but offering additional switching capability.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: PVT412PBF is the direct replacement for PVT412. This part maintains identical electrical specifications and 6-DIP package configuration while offering active product status and ROHS3 compliance. No design modifications are required for PCB layout or firmware integration.

Secondary Recommendations for New Designs:

AQV104 and AQV204 (Panasonic PhotoMOS™ series) provide superior on-state resistance characteristics (8 and 16 Ohms respectively) compared to the original PVT412 (27 Ohms), resulting in lower power dissipation. Both maintain 0-400V load voltage capability and 6-DIP packaging. AQV104 exceeds the original 140mA load current specification at 180mA. Both are ROHS3 compliant and active products.

ASSR-4111-001E (Broadcom ASSR series) offers comparable on-state resistance (25 Ohms) to the original PVT412 with active product status and ROHS3 compliance. Load current capability is 120mA, which is acceptable for applications not requiring the full 140mA specification.

Conditional Recommendations:

LCA100 (IXYS OptoMOS®) is suitable only for applications where load voltage does not exceed 350V. Input voltage matching (1.2VDC) and on-state resistance (25 Ohms) are equivalent to PVT412. Product is active and ROHS3 compliant.

XCA170 (IXYS OptoMOS®) is suitable only for applications requiring maximum 100mA load current and 350V load voltage. This part represents a reduced-capability alternative and should be selected only when application requirements permit these limitations.

LH1502BB (Vishay) requires 8-DIP package accommodation and PCB layout modification. This part is recommended only for applications requiring dual-circuit functionality (SPST-NO + SPST-NC). Load voltage is limited to 350V.

Compliance Consideration: All recommended active substitutes are ROHS3 compliant, addressing the non-compliance status of the original PVT412 for applications subject to RoHS regulations.

Frequently Asked Questions (FAQ)

Q: Can PVT412PBF be used as a direct drop-in replacement for PVT412?

A: Yes. PVT412PBF maintains identical electrical specifications (1.2VDC input, 0-400V load voltage, 140mA load current, 27 Ohms on-state resistance) and 6-DIP package configuration. No PCB modifications or design changes are required. The primary difference is product status (active vs. obsolete) and RoHS compliance (ROHS3 vs. non-compliant).

Q: What is the difference between the Panasonic AQV series alternatives?

A: AQV104, AQV204, and AQV214EH differ in load current capability and on-state resistance. AQV104 provides 180mA at 8 Ohms (lowest resistance, highest current). AQV204 provides 150mA at 16 Ohms. AQV214EH provides 120mA at 50 Ohms (lowest input voltage requirement at 1.14VDC). All three maintain 0-400V load voltage and 6-DIP packaging. Selection depends on specific application current and resistance requirements.

Q: Why does LH1502BB require package modification?

A: LH1502BB uses an 8-DIP package compared to the 6-DIP package of PVT412. This requires PCB footprint redesign and layout modification. Additionally, LH1502BB provides dual-circuit functionality (SPST-NO + SPST-NC), which may not be necessary for applications requiring only single-pole switching. Load voltage is also limited to 350V.

Q: Are all substitute parts compatible with 400V load voltage?

A: No. XCA170 and LCA100 are limited to 350V load voltage. LH1502BB is also limited to 350V. These parts are suitable only for applications not requiring the full 400V capability of the original PVT412. PVT412PBF, AQV104, AQV204, and AQV214EH all support 0-400V load voltage.

Q: What is the significance of input voltage differences among substitutes?

A: Input voltage specifications (1.2VDC to 2.3VDC) indicate the control signal voltage required to activate the relay. PVT412 and PVT412PBF require 1.2VDC. Panasonic AQV series parts require 2.3VDC (AQV104, AQV204) or 1.14VDC (AQV214EH). ASSR-4111-001E requires 1.3VDC. LCA100 and XCA170 require 1.2VDC. Selection must ensure the control circuit can provide the required input voltage for the chosen substitute.

Q: Which substitute offers the lowest on-state resistance?

A: AQV104 provides the lowest on-state resistance at 8 Ohms maximum, compared to 27 Ohms for the original PVT412. Lower on-state resistance reduces power dissipation and heat generation during switching operation. This characteristic makes AQV104 suitable for applications prioritizing thermal performance.

Q: Are all substitutes RoHS compliant?

A: All active substitute parts listed (PVT412PBF, AQV104, AQV204, AQV214EH, ASSR-4111-001E, LCA100, XCA170, LH1502BB) are ROHS3 compliant. The original PVT412 is RoHS non-compliant. Compliance status is relevant for applications subject to RoHS regulations or customer requirements.
