AQZ264 Equivalent & Substitute Parts

Part Overview

The AQZ264 is a solid-state relay (SSR) manufactured by Panasonic Electric Works, configured as a SPST-NO (Single Pole Single Throw - Normally Open) relay with 1A load capacity and 0-400V output voltage range. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations.

The AQZ264 belongs to the PhotoMOS™ AQZ series and is mounted through-hole in a 4-SIP package configuration. Due to its obsolete status, direct replacement with active production alternatives is necessary for procurement and long-term supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AQZ264 is determined by the following critical parameters that must remain compatible:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching topology
• Load Current Rating: Must be rated for minimum 1 A continuous operation
• Output Voltage Range: Substitute must support the operating voltage window of the original application
• Input Voltage: Must be compatible with the control signal voltage of 1.16 VDC or higher
• Package / Case: Must be 4-SIP to ensure mechanical and electrical compatibility with existing PCB layouts
• Mounting Type: Must be Through Hole to match board assembly requirements
• Termination Style: Must use PC Pin configuration for direct socket compatibility

The AQZ206G2 qualifies as a direct substitute because it maintains identical circuit configuration, load current rating, package type, mounting method, and termination style. The substitute offers enhanced specifications in voltage range (0-600V vs. 0-400V) and improved on-state resistance (800 mOhms vs. 1.4 Ohms), making it a superior replacement for the obsolete AQZ264.

Parameter Comparison

Engineering Selection Recommendations

The AQZ206G2 is the appropriate substitute for the obsolete AQZ264 based on the following engineering criteria:

Product Status & Availability: The AQZ264 is obsolete, whereas the AQZ206G2 is in active production status, ensuring long-term availability and supply chain continuity.

Compliance & Certifications: The AQZ206G2 carries ROHS3 compliance and REACH Unaffected status, meeting current environmental and regulatory requirements for electronic component procurement.

Electrical Compatibility: Both parts maintain identical circuit topology (SPST-NO), load current rating (1 A), and output type (AC/DC). The AQZ206G2 extends the maximum load voltage from 400V to 600V, providing enhanced operational margin without compromising the original 400V application requirement.

Mechanical Compatibility: Identical package (4-SIP), mounting type (Through Hole), and termination style (PC Pin) ensure direct board-level substitution without layout modifications.

Performance Enhancement: The AQZ206G2 provides superior on-state resistance (800 mOhms vs. 1.4 Ohms), resulting in lower power dissipation and improved thermal performance in the same package footprint.

Frequently Asked Questions (FAQ)

Q: Can the AQZ206G2 directly replace the AQZ264 without PCB modifications?

A: Yes. Both parts use identical 4-SIP package configuration with PC Pin termination and Through Hole mounting. No PCB layout changes are required for direct substitution.

Q: What is the significance of the increased voltage range (600V vs. 400V) in the AQZ206G2?

A: The AQZ206G2 supports a higher maximum load voltage of 600V compared to the AQZ264's 400V. This provides additional design margin and allows the substitute to operate safely in applications with higher voltage transients or future design upgrades, while remaining fully compatible with 400V applications.

Q: Are there input voltage compatibility concerns between the two parts?

A: The input voltage specifications are closely matched (1.16 VDC for AQZ264 vs. 1.25 VDC for AQZ206G2). Both operate within standard logic-level control signal ranges and are compatible with identical drive circuits.

Q: Does the lower on-state resistance of the AQZ206G2 affect circuit operation?

A: The reduced on-state resistance (800 mOhms vs. 1.4 Ohms) in the AQZ206G2 is a performance improvement that decreases power dissipation and heat generation. This does not negatively impact circuit operation and is fully backward compatible with designs expecting the higher resistance of the original part.

Q: What compliance advantages does the AQZ206G2 offer?

A: The AQZ206G2 is ROHS3 compliant and REACH Unaffected, meeting current environmental regulations. The AQZ264 specifications do not include these compliance certifications, making the substitute the appropriate choice for new designs and regulated applications.

Q: Is the AQZ206G2 available in the same packaging format?

A: Yes. The AQZ206G2 is supplied in Tube packaging in 4-SIP configuration, maintaining mechanical and electrical compatibility with the original AQZ264 design.
