PVT412LS-T Equivalent & Substitute Parts

Part Overview

The PVT412LS-T is a solid-state relay (SSR) manufactured by Infineon Technologies, configured as a SPST-NO (Single Pole Single Throw - Normally Open) switch with 120 mA load capacity and 0-400V output voltage range. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The part operates with 1.2VDC input and features a 35 Ohm maximum on-state resistance in a 6-SMD surface mount package.

Substitute Part Grouping Explanation

Substitution eligibility for the PVT412LS-T is determined by the following critical parameters:

Primary Compatibility Criteria:

Circuit configuration: SPST-NO (1 Form A)
Output type: AC, DC capable
Load voltage range: 0 V ~ 400 V
Package / Case: 6-SMD (0.300", 7.62mm)
Mounting type: Surface Mount
Termination style: Gull Wing

Secondary Compatibility Criteria:

Load current: 120 mA minimum
On-state resistance: 35 Ohms maximum
Input voltage: 1.2VDC nominal (tolerance range 1.14VDC - 1.3VDC acceptable)

Substitute parts are grouped into two categories: direct equivalents from Infineon (PVT412LS-TPBF) and cross-manufacturer alternatives from Panasonic Electric Works (AQV series) and Broadcom Limited (ASSR series). All listed substitutes maintain identical load voltage ranges, circuit configurations, and package specifications. Variations in on-state resistance and input voltage are within acceptable engineering tolerances for this application class.

Engineering Selection Recommendations

Direct Equivalent (Recommended Primary Choice): PVT412LS-TPBF is the active production equivalent from Infineon Technologies. It maintains identical electrical specifications to the obsolete PVT412LS-T while offering ROHS3 compliance and active product status. This part provides the most direct replacement path with no design modifications required.

Panasonic PhotoMOS™ AQV Series (120 mA Load Current): AQV214EHA, AQV214EHAX, and AQV214EHAZ are functionally equivalent alternatives with 120 mA load current capacity. These parts feature lower input voltage (1.14VDC) and higher on-state resistance (50 Ohms maximum) compared to the original specification. All variants are ROHS3 compliant and in active production status. Packaging options include Tube (AQV214EHA) and Tape & Reel configurations (AQV214EHAX, AQV214EHAZ).

Panasonic PhotoMOS™ AQV Series (150 mA Load Current): AQV254HA, AQV254HAX, and AQV254HAZ provide enhanced load current capacity at 150 mA with significantly lower on-state resistance (16 Ohms maximum). These parts exceed the original 120 mA specification and are suitable for applications requiring improved current handling or reduced resistive losses. All variants maintain 0-400V load voltage range and are in active production with RoHS compliance.

Broadcom ASSR Series: ASSR-4111-301E and ASSR-4111-501E maintain 120 mA load current with superior on-state resistance (25 Ohms maximum) and higher input voltage tolerance (1.3VDC). Both variants are ROHS3 compliant and in active production. Packaging options include Tube (ASSR-4111-301E) and Tape & Reel (ASSR-4111-501E). MSL rating of 1 (Unlimited) provides superior moisture handling compared to the original MSL 4 specification.

Frequently Asked Questions (FAQ)

Q: Can I directly replace PVT412LS-T with PVT412LS-TPBF without design changes? A: Yes. PVT412LS-TPBF is the active production equivalent with identical electrical and mechanical specifications. The only differences are product status (Active vs. Obsolete) and RoHS compliance (ROHS3 vs. non-compliant). No circuit modifications are required.

Q: What are the key differences between Infineon PVT412LS-TPBF and Panasonic AQV214EHA? A: Both support 120 mA load current and 0-400V output voltage. Differences include: input voltage (1.2VDC vs. 1.14VDC), on-state resistance (35 Ohms vs. 50 Ohms maximum), and manufacturer. The Panasonic part has lower input voltage tolerance and higher resistance but maintains functional compatibility.

Q: When should I use AQV254 series instead of AQV214 series? A: The AQV254 series provides 150 mA load current capacity versus 120 mA for AQV214, with significantly lower on-state resistance (16 Ohms vs. 50 Ohms). Use AQV254 when your application requires higher current handling or when reduced resistive heating is a design priority.

Q: What is the difference between Tape & Reel and Tube packaging options? A: Tube packaging (standard packaging) is suitable for lower-volume applications and manual assembly. Tape & Reel packaging is optimized for automated pick-and-place assembly in high-volume production. Electrical specifications remain identical; packaging choice depends on manufacturing process requirements.

Q: Are all substitute parts RoHS compliant? A: All listed substitute parts are RoHS compliant (either RoHS or ROHS3 status). The original PVT412LS-T is RoHS non-compliant. If RoHS compliance is a design requirement, any of the listed substitutes satisfy this criterion.

Q: Can I use ASSR-4111 series as a drop-in replacement? A: ASSR-4111-301E and ASSR-4111-501E are functionally compatible with identical 120 mA load current and 0-400V voltage range. The lower on-state resistance (25 Ohms vs. 35 Ohms) and higher input voltage (1.3VDC vs. 1.2VDC) represent improvements. No design changes are required for substitution.

Q: What does MSL rating mean and why does it matter? A: MSL (Moisture Sensitivity Level) indicates the component's sensitivity to moisture during storage and handling. The original PVT412LS-T has MSL 4 (72 Hours), requiring controlled storage conditions. ASSR-4111 series offers MSL 1 (Unlimited), eliminating moisture-related storage constraints. Panasonic AQV series components are not applicable for MSL rating.
