AQV214AX Equivalent & Substitute Parts

Part Overview

The AQV214AX is a solid-state relay (SSR) manufactured by Panasonic Electric Works, part of the PhotoMOS™ AQV series. This SPST-NO (1 Form A) surface mount component is designed for switching applications with AC and DC loads up to 400V. The device is actively produced and RoHS compliant, making it suitable for modern industrial and consumer electronics applications. Substitute parts may be required due to inventory constraints, regional availability, or specific application performance requirements within the allowed electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AQV214AX is permissible when the alternative component maintains compatibility across the following critical parameters:

• Circuit configuration: SPST-NO (1 Form A) topology
• Load voltage range: 0 V ~ 400 V maximum
• Output type: AC and DC switching capability
• Package / Case: 6-SMD (0.300", 7.62mm) form factor
• Mounting type: Surface Mount with Gull Wing termination
• Packaging format: Tape & Reel (TR)

The LH1525AABTR from Vishay Semiconductor Opto Division satisfies all substitution criteria. While the substitute part offers higher load current capacity (250 mA versus 120 mA) and lower on-state resistance (36 Ohms versus 50 Ohms), these represent performance enhancements rather than deviations from the allowed parameter set. Input voltage and load voltage specifications remain within compatible ranges.

Parameter Comparison

Engineering Selection Recommendations

Both the AQV214AX and LH1525AABTR are active production components with current RoHS compliance certifications. The AQV214AX maintains RoHS Compliant status, while the LH1525AABTR carries ROHS3 Compliant designation, indicating adherence to the most recent regulatory requirements. Both components are classified under EAR99 export control and are suitable for applications requiring solid-state relay functionality in the 0 V to 400 V load voltage range.

Selection between these parts should be based on application-specific current requirements and inventory availability. The LH1525AABTR provides enhanced current handling capacity and reduced on-state resistance, making it suitable for applications approaching or exceeding the 120 mA load current specification of the AQV214AX.

Frequently Asked Questions (FAQ)

Q: Can the LH1525AABTR directly replace the AQV214AX in existing designs?

A: Yes, the LH1525AABTR is a direct substitute. Both components share identical package dimensions (6-SMD, 0.300" / 7.62mm), mounting type (Surface Mount), termination style (Gull Wing), and circuit configuration (SPST-NO). PCB layout and footprints are compatible without modification.

Q: What are the key differences between these two SSR relays?

A: The primary differences are load current capacity (AQV214AX: 120 mA; LH1525AABTR: 250 mA) and on-state resistance (AQV214AX: 50 Ohms max; LH1525AABTR: 36 Ohms max). Input voltage and load voltage specifications are functionally equivalent. The LH1525AABTR represents a higher-performance alternative.

Q: Are there any compliance or certification differences?

A: Both components are RoHS compliant. The AQV214AX carries standard RoHS Compliant status, while the LH1525AABTR carries ROHS3 Compliant status, reflecting the latest regulatory standards. Both are EAR99 classified for export purposes.

Q: What packaging formats are available for these parts?

A: Both the AQV214AX and LH1525AABTR are supplied in Tape & Reel (TR) format, standard for surface mount production environments. Package dimensions are 6-SMD with 0.300" (7.62mm) spacing.

Q: Can these relays handle both AC and DC loads?

A: Yes, both components are rated for AC and DC output switching across the 0 V to 400 V load voltage range. Circuit configuration remains SPST-NO (1 Form A) for both alternatives.
