AQW654 Equivalent & Substitute Parts

Part Overview

The AQW654 is a solid-state relay manufactured by Panasonic Electric Works, part of the PhotoMOS™ AQW series. It features a SPST-NO + SPST-NC configuration (1 Form A and B) in an 8-DIP package with a maximum load current of 120 mA and load voltage range of 0–400 V. The component is actively produced and RoHS compliant, making it suitable for industrial control, switching, and signal isolation applications requiring dual-channel relay functionality. Equivalent parts are identified when they maintain the same circuit configuration, package type, load current rating, and compatible voltage specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AQW654 are qualified based on the following criteria:

• Circuit configuration must be SPST-NO + SPST-NC (1 Form A and B)
• Package type must be 8-DIP (0.300", 7.62mm) for mechanical and electrical compatibility
• Load current rating must be 120 mA
• Load voltage range must support the application requirements (0–400 V for AQW654)
• Termination style must be PC Pin for PCB mounting compatibility
• Output type must support both AC and DC switching

The LBA110 meets these substitution criteria. It maintains identical circuit configuration and package specifications, supports the same 120 mA load current, and operates within a compatible voltage range (0–350 V). Both components are active products with current manufacturing status and appropriate compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the AQW654 and LBA110 are active products with current manufacturing support and appropriate regulatory compliance. The AQW654 offers a higher maximum load voltage (400 V vs. 350 V) and lower on-state resistance (16 Ohms vs. 35 Ohms), making it preferable for applications requiring maximum voltage headroom or minimal resistive losses. The LBA110 is suitable for applications with load voltages up to 350 V and can accommodate the slightly higher on-state resistance. Both components maintain identical circuit configuration, package type, and load current specifications, ensuring mechanical and functional compatibility in 8-DIP through-hole PCB designs. Selection should be based on specific application voltage requirements and on-state resistance constraints.

Frequently Asked Questions (FAQ)

Q: Can the LBA110 replace the AQW654 in all applications?

A: The LBA110 is mechanically and functionally compatible with the AQW654 in applications where the load voltage does not exceed 350 V. If your application requires operation above 350 V, the AQW654 is required. Additionally, the higher on-state resistance of the LBA110 (35 Ohms vs. 16 Ohms) may affect power dissipation in high-current switching scenarios.

Q: Are the package dimensions identical?

A: Yes. Both the AQW654 and LBA110 use the 8-DIP (0.300", 7.62mm) package with PC Pin termination, ensuring identical PCB footprint and mounting compatibility.

Q: What is the significance of the input voltage difference (1.14 VDC vs. 1.2 VDC)?

A: Both input voltages fall within typical logic-level control ranges. The 0.06 VDC difference is negligible for standard digital control circuits and does not affect practical substitution compatibility.

Q: Do both parts support AC and DC load switching?

A: Yes. Both the AQW654 and LBA110 are rated for AC and DC output switching, providing flexibility for various load types.

Q: What compliance certifications apply to these parts?

A: The AQW654 is RoHS Compliant. The LBA110 is ROHS3 Compliant and REACH Unaffected. Both meet current environmental and regulatory standards for industrial component use.
