AQW614AX Equivalent & Substitute Parts

Part Overview

The AQW614AX is a solid-state relay manufactured by Panasonic Electric Works, part of the PhotoMOS™ AQW series. This component functions as a SPST-NO/NC (1 Form A and B) relay with a maximum load current of 100 mA and load voltage range of 0 V to 400 V. The device is surface-mounted in an 8-SMD package with gull wing termination and is RoHS compliant. As an active product with 1437 units in stock, substitute parts may be required for design flexibility, supply chain optimization, or when specific performance parameters better suit application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AQW614AX is determined by the following critical parameters:

• Circuit configuration must be SPST-NO + SPST-NC (1 Form A and B)
• Package type must be 8-SMD (0.300", 7.62mm) with gull wing termination
• Mounting type must be surface mount
• Load voltage range must accommodate 0 V to 400 V operation
• Load current capability must meet or exceed 100 mA
• Output type must support both AC and DC loads
• Input voltage must be compatible with 1.14 VDC control signal

The LH1502BACTR from Vishay Semiconductor Opto Division qualifies as a substitute based on matching circuit configuration, package dimensions, termination style, and mounting type. While the LH1502BACTR has a reduced load voltage range (0 V to 350 V) and increased load current capability (150 mA), these parameters remain within acceptable substitution criteria for applications not requiring the full 400 V load voltage specification.

Parameter Comparison

Engineering Selection Recommendations

Both the AQW614AX and LH1502BACTR are active products with current manufacturing status and full RoHS compliance. The AQW614AX maintains a 400 V load voltage specification, making it suitable for applications requiring the full voltage range. The LH1502BACTR operates at a maximum load voltage of 350 V but provides superior on-state resistance (20 Ohms versus 50 Ohms) and higher load current capability (150 mA versus 100 mA), resulting in lower power dissipation and improved current handling for applications within the 350 V load voltage envelope.

Selection between these parts should be based on specific application voltage and current requirements. Applications requiring 350 V to 400 V load voltage operation must use the AQW614AX. Applications operating at 350 V or below may benefit from the LH1502BACTR's lower on-state resistance and higher current rating.

Frequently Asked Questions (FAQ)

Q: Can the LH1502BACTR replace the AQW614AX in all applications?

A: The LH1502BACTR is suitable for applications where the load voltage does not exceed 350 V. Applications requiring operation above 350 V must use the AQW614AX.

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

A: The LH1502BACTR has a maximum on-state resistance of 20 Ohms compared to 50 Ohms for the AQW614AX. Lower on-state resistance reduces power dissipation and heat generation during relay operation.

Q: Are the packages physically identical?

A: Both parts use the 8-SMD (0.300", 7.62mm) package with gull wing termination, ensuring identical PCB footprints and reflow soldering compatibility.

Q: What is the input voltage difference between these parts?

A: The AQW614AX requires 1.14 VDC input, while the LH1502BACTR requires 1.26 VDC input. Control circuit design must accommodate the respective input voltage specifications.

Q: Are both parts RoHS compliant?

A: Yes. The AQW614AX is RoHS compliant, and the LH1502BACTR is ROHS3 compliant, both meeting current environmental regulations.
