PVU414S-T Solid State Relay - Equivalent & Substitute Parts

Part Overview

The PVU414S-T 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 designed for switching applications requiring AC or DC loads up to 400V with a maximum load current of 140mA. The part is currently classified as Obsolete, making identification of suitable substitute components essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PVU414S-T is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit Configuration: SPST-NO (1 Form A)
• Output Type: AC, DC
• Load Voltage Range: 0V ~ 400V
• Package / Case: 6-SMD (0.300", 7.62mm)
• Mounting Type: Surface Mount
• Termination Style: Gull Wing

Performance Parameters (Allowable Variance):

• Input Voltage: 1.2VDC nominal (substitutes within ±0.2V acceptable)
• Load Current: 140mA minimum requirement (substitutes with equal or higher rating acceptable)
• On-State Resistance: 27 Ohms maximum (lower values acceptable)

Substitute parts must maintain identical mechanical and electrical interface characteristics to ensure PCB compatibility and functional equivalence in the target application.

Parameter Comparison

Engineering Selection Recommendations

PVU414S-TPBF (Infineon Technologies): This part represents the direct successor to the obsolete PVU414S-T within the Infineon PVU series. It maintains identical electrical specifications and mechanical packaging while offering Active product status and ROHS3 compliance. The packaging format transitions from loose components to Tape & Reel (TR) configuration, which is standard for production environments. This substitute is the preferred choice for applications requiring continuity with the original Infineon HEXFET® platform.

AQV254HAZ (Panasonic Electric Works): This PhotoMOS™ AQV series component provides functional equivalence with enhanced performance characteristics. The load current rating of 150mA exceeds the original 140mA requirement, and the on-state resistance of 16 Ohms is superior to the original 27 Ohms specification. Input voltage of 1.14VDC is within acceptable tolerance of the original 1.2VDC. The MSL rating is Not Applicable, indicating superior moisture handling characteristics. ROHS3 compliance is confirmed. This substitute is suitable for applications where improved electrical performance and moisture resistance are beneficial.

Both substitutes maintain identical circuit configuration, load voltage range, package dimensions, and mounting characteristics, ensuring direct PCB compatibility with designs originally specified for the PVU414S-T.

Frequently Asked Questions (FAQ)

Q: Can PVU414S-TPBF be used as a direct replacement for PVU414S-T?

A: Yes. Both parts share identical electrical specifications (1.2VDC input, 0-400V load voltage, 140mA load current, 27 Ohms on-state resistance) and mechanical packaging (6-SMD, Gull Wing termination). The primary difference is product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. loose components). PCB layout and circuit design require no modification.

Q: What are the key differences between the Infineon and Panasonic substitutes?

A: Both maintain the same circuit configuration and load voltage range. The AQV254HAZ offers higher load current capacity (150mA vs. 140mA), lower on-state resistance (16 Ohms vs. 27 Ohms), and superior moisture handling (MSL Not Applicable vs. MSL 4). Input voltage differs slightly (1.14VDC vs. 1.2VDC), which remains within acceptable operating margins. Both are ROHS3 compliant.

Q: Are there any package compatibility concerns when substituting these parts?

A: No. All three parts use identical 6-SMD (0.300", 7.62mm) packaging with Gull Wing termination. Surface mount footprints are mechanically and electrically compatible. No PCB redesign is required.

Q: Which substitute should be selected for new production designs?

A: Selection depends on supply chain and performance requirements. PVU414S-TPBF maintains the original Infineon platform with proven compatibility. AQV254HAZ provides enhanced electrical performance and moisture resistance. Both are Active products with ROHS3 compliance suitable for production environments.

Q: Does the input voltage difference between substitutes affect circuit design?

A: The input voltage specifications (1.2VDC for Infineon parts, 1.14VDC for Panasonic) represent nominal ratings. Both values fall within standard logic-level control voltage ranges and do not require circuit modification. Existing gate drive circuits designed for the original part will operate correctly with either substitute.
