AQV258HAZ Equivalent & Substitute Parts

Part Overview

The AQV258HAZ is a solid-state relay (SSR) manufactured by Panasonic Electric Works, part of the PhotoMOS™ AQV series. It functions as a SPST-NO (Single Pole Single Throw - Normally Open) relay with a 1 Form A circuit configuration, designed for switching applications requiring 20 mA load current across 0–1500 V AC/DC loads. The device is packaged in a 6-SMD surface-mount configuration with gull wing termination.

The AQV258HAZ is currently listed as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AQV258HAZ is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST-NO (1 Form A)
• Output type: AC, DC
• Load voltage range: 0 V ~ 1500 V
• Load current: 20 mA
• On-state resistance (max): 500 Ohms
• Package / case: 6-SMD (0.300", 7.62mm)
• Termination style: Gull Wing
• Mounting type: Surface Mount
• Base product number: AQV258

The substitute parts identified—AQV258AX and AQV258H5AZ—maintain electrical equivalence across all load-side parameters and mechanical compatibility. Variations in input voltage specification and packaging format do not preclude substitution when the load-side electrical characteristics and physical footprint remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both AQV258AX and AQV258H5AZ are active production parts from Panasonic Electric Works and are direct functional equivalents to the obsolete AQV258HAZ. Selection between these substitutes should be based on the following criteria:

AQV258AX is recommended as the primary substitute. It maintains identical electrical specifications across all load-side parameters and input voltage, with active product status and standard packaging availability. This part provides the most direct replacement path with no design modifications required.

AQV258H5AZ is an alternative substitute with active product status. It differs in input voltage specification (1.32 VDC versus 1.14 VDC) and is supplied in Tape & Reel packaging. This part is electrically equivalent on the load side and mechanically compatible. The higher input voltage specification may require circuit-level evaluation if the control signal source is voltage-constrained.

Both substitute parts are RoHS compliant and carry identical ECCN and HTSUS classifications as the original part, ensuring regulatory and compliance continuity.

Frequently Asked Questions (FAQ)

Q: Can AQV258AX be used as a direct replacement for AQV258HAZ without PCB modifications?

A: Yes. AQV258AX is electrically and mechanically equivalent. The 6-SMD gull wing package, load voltage range (0–1500 V), load current (20 mA), and on-state resistance (500 Ohms max) are identical. No PCB layout changes are required.

Q: What is the difference between AQV258AX and AQV258H5AZ?

A: Both are functionally equivalent on the load side. AQV258H5AZ specifies a higher input voltage (1.32 VDC versus 1.14 VDC) and is supplied in Tape & Reel packaging. The package designation notes "5 Leads" for AQV258H5AZ. Verify control signal voltage compatibility with your circuit design before selection.

Q: Are all three parts pin-compatible?

A: AQV258AX and AQV258HAZ are pin-compatible with identical 6-SMD gull wing footprints. AQV258H5AZ uses the same 6-SMD package but specifies 5 leads in its package designation. Confirm lead count and pinout against your PCB design before substitution.

Q: Why is AQV258HAZ listed as obsolete?

A: Product obsolescence is determined by the manufacturer. AQV258AX and AQV258H5AZ are active alternatives within the same PhotoMOS™ AQV series, providing continued access to equivalent solid-state relay functionality.

Q: Do all three parts meet RoHS compliance requirements?

A: Yes. AQV258HAZ, AQV258AX, and AQV258H5AZ are all RoHS compliant and carry identical ECCN (EAR99) and HTSUS (8536.41.0030) classifications.

Q: What load types are supported by these relays?

A: All three parts support both AC and DC loads across the 0–1500 V range at 20 mA maximum load current. On-state resistance is specified at 500 Ohms maximum for all variants.
