PVU414PBF Equivalent & Substitute Parts

Part Overview

The PVU414PBF is a solid-state relay (SSR) manufactured by Infineon Technologies, configured as a SPST-NO (Single Pole Single Throw - Normally Open) device in a 6-DIP through-hole package. This component is rated for 140 mA load current across 0–400 V AC/DC output with a 1.2 VDC input trigger voltage. The part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production support. Substitute parts must maintain electrical compatibility across input voltage, load voltage range, load current capacity, and on-state resistance while accommodating different mounting technologies and product statuses.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PVU414PBF is determined by the following criteria:

Electrical Compatibility Requirements:

• Circuit configuration must be SPST-NO (1 Form A)
• Output type must support AC and DC
• Load voltage range must encompass 0–400 V
• Load current capacity must meet or exceed 140 mA
• Input voltage must be compatible with 1.2 VDC trigger level (tolerance range: 1.14–1.3 VDC acceptable)
• On-state resistance must not exceed 27 Ohms (lower values are acceptable)

Mechanical & Packaging Compatibility:

• Package must be 6-DIP format with 0.300" (7.62mm) pitch
• Termination style must be PC Pin for through-hole mounting
• Mounting type must be through-hole

Compliance & Status:

• RoHS3 compliance required
• Product status: Active preferred; obsolete acceptable only if no active alternative exists

Three substitute parts meet these criteria with varying trade-offs in electrical performance and product availability.

Engineering Selection Recommendations

For Through-Hole PCB Designs (Direct Pin-Compatible Substitutes):

AQV254H (Panasonic PhotoMOS™ AQV series) is the preferred substitute when load current capacity is the primary design constraint. This part exceeds the 140 mA requirement with 150 mA rated capacity and delivers superior on-state resistance (16 Ohms vs. 27 Ohms), reducing power dissipation. Input voltage tolerance (1.14 VDC) is within acceptable range. Product status is active with full RoHS3 compliance.

AQV214EH (Panasonic PhotoMOS™ AQV series) is suitable for applications where load current can be reduced to 120 mA. On-state resistance is higher (50 Ohms), resulting in increased power dissipation. This part is active and RoHS3 compliant.

ASSR-4111-001E (Broadcom ASSR series) provides a middle-ground option with 120 mA load current and 25 Ohms on-state resistance. Input voltage (1.3 VDC) is at the upper tolerance limit. Product status is active with full RoHS3 compliance.

For Surface-Mount PCB Designs:

PVU414S-TPBF (Infineon PVU series) maintains identical electrical specifications to the original PVU414PBF (140 mA, 27 Ohms, 1.2 VDC input) but uses surface-mount technology (6-SMD, Gull Wing termination). This part is active and RoHS3 compliant, making it the optimal choice for new surface-mount designs requiring exact electrical equivalence.

Selection Priority:

1. PVU414S-TPBF for surface-mount applications requiring exact electrical equivalence
2. AQV254H for through-hole applications prioritizing load current capacity and low on-state resistance
3. ASSR-4111-001E for through-hole applications with moderate current requirements
4. AQV214EH for through-hole applications where 120 mA load current is acceptable

Frequently Asked Questions (FAQ)

Q: Can PVU414S-TPBF replace PVU414PBF in existing through-hole designs?

A: No. PVU414S-TPBF uses surface-mount technology (6-SMD, Gull Wing termination) and cannot be directly soldered into through-hole PCB footprints designed for the PVU414PBF (6-DIP, PC Pin). PCB redesign is required for surface-mount implementation.

Q: What is the minimum load current capacity required for a substitute part?

A: The substitute must support at least 140 mA to maintain electrical equivalence with PVU414PBF. AQV214EH and ASSR-4111-001E are rated for 120 mA and are acceptable only if the application load current does not exceed 120 mA.

Q: How does on-state resistance affect component selection?

A: On-state resistance determines power dissipation in the relay. Lower resistance reduces heat generation. AQV254H (16 Ohms) dissipates less power than PVU414PBF (27 Ohms), while AQV214EH (50 Ohms) dissipates significantly more. Select based on thermal design constraints and power budget.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitutes (PVU414S-TPBF, AQV214EH, AQV254H, ASSR-4111-001E) are RoHS3 compliant and suitable for applications requiring regulatory compliance.

Q: What is the input voltage tolerance range for substitute selection?

A: The original PVU414PBF operates at 1.2 VDC input. Substitutes with input voltages between 1.14 VDC and 1.3 VDC are electrically compatible. All listed substitutes fall within this range.

Q: Can I use AQV214EH or ASSR-4111-001E if my application requires 140 mA load current?

A: No. These parts are rated for 120 mA maximum load current. Using them in applications requiring 140 mA will exceed their rated capacity and may cause premature failure. Use AQV254H (150 mA) or PVU414S-TPBF (140 mA) for full current compatibility.

Q: What is the difference between PC Pin and Gull Wing termination?

A: PC Pin termination is designed for through-hole mounting with vertical leads inserted into PCB holes. Gull Wing termination is designed for surface-mount technology with leads bent outward for solder reflow. These are mechanically incompatible and require different PCB footprints.
