AQV454HAZ Equivalent & Substitute Parts

Part Overview

The AQV454HAZ is an active production solid-state relay (SSR) manufactured by Panasonic Electric Works. This SPST-NC (1 Form B) device operates as a photoMOS relay with a 150 mA load current capacity and supports both AC and DC output switching across 0–400 V. The part is housed in a 6-SMD surface-mount package with gull-wing termination and is RoHS compliant. Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits functional alternatives within the same electrical and mechanical parameter envelope.

Substitute Part Grouping Explanation

Substitution of the AQV454HAZ is permissible when the alternative part meets the following criteria:

• Circuit configuration: SPST-NC (1 Form B)
• Output type: AC and DC switching capability
• Load voltage range: 0 V – 400 V minimum
• Load current: Equal to or greater than 150 mA
• Package / case: 6-SMD (0.300", 7.62 mm)
• Termination style: Gull Wing
• Mounting type: Surface Mount
• Input voltage compatibility: Within the specified operating range

The PLB190S from IXYS Integrated Circuits Division satisfies these substitution criteria. Both parts share identical mechanical packaging, circuit topology, and voltage/current operating ranges within acceptable engineering tolerances.

Parameter Comparison

Engineering Selection Recommendations

Both the AQV454HAZ and PLB190S are active production components with current RoHS compliance certifications. The PLB190S is a functional substitute when load current requirements do not exceed 130 mA and when the higher on-state resistance of 25 Ohms is acceptable for the application. The input voltage difference of 0.06 VDC is negligible for practical circuit design. Selection between these parts should be based on availability, cost, and specific load current and resistance requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can the PLB190S replace the AQV454HAZ in all applications?

A: The PLB190S is a functional substitute when the application load current does not exceed 130 mA. If the design requires the full 150 mA capacity of the AQV454HAZ, the PLB190S is not suitable.

Q: What is the significance of the on-state resistance difference?

A: The AQV454HAZ has a maximum on-state resistance of 16 Ohms, while the PLB190S is rated at 25 Ohms. This 9 Ohm difference affects power dissipation and voltage drop across the relay contacts. Applications sensitive to these parameters must account for this variance.

Q: Are the packages mechanically identical?

A: Yes. Both parts use a 6-SMD (0.300", 7.62 mm) package with gull-wing termination, permitting direct PCB footprint compatibility without layout modification.

Q: Do both parts support AC and DC switching?

A: Yes. Both the AQV454HAZ and PLB190S support AC and DC output switching across the 0 V – 400 V load voltage range.

Q: What is the input voltage requirement difference?

A: The AQV454HAZ requires 1.14 VDC input, while the PLB190S requires 1.2 VDC input. This 0.06 VDC difference is typically insignificant in practical circuit implementations.

Q: Are both parts RoHS compliant?

A: Yes. The AQV454HAZ is RoHS Compliant, and the PLB190S is ROHS3 Compliant. Both meet current environmental and regulatory standards.
