AQW210 Equivalent & Substitute Parts

Part Overview

The AQW210 is a solid-state relay (SSR) manufactured by Panasonic Electric Works, part of the PhotoMOS™ AQW series. This SPST-NO (1 Form A) x 2 configuration operates as a through-hole 8-DIP component rated for 120 mA load current across 0–350 V AC/DC output voltage. The device is actively produced and ROHS3 compliant, making it suitable for industrial switching applications requiring galvanic isolation and silent operation. Equivalent parts are identified when alternative manufacturers offer SSR relays with matching electrical specifications and identical package geometry, enabling direct socket replacement in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AQW210 is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPST-NO (1 Form A) x 2 topology
• Package Geometry: 8-DIP (0.300", 7.62mm) with PC Pin termination
• Electrical Ratings: Load voltage range 0–350 V, load current 120 mA, on-state resistance maximum 35 Ohms
• Output Capability: AC and DC switching support
• Input Voltage: Control signal requirement of approximately 1.14–1.2 VDC
• Compliance: ROHS3 compliance and REACH unaffected status

The LAA110 (IXYS Integrated Circuits Division, OptoMOS® series) meets all substitution criteria. Both devices share identical package footprints, electrical load specifications, and regulatory compliance, enabling direct replacement in PCB designs without layout modification.

Parameter Comparison

Engineering Selection Recommendations

Both the AQW210 and LAA110 are active production components with ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current and future applications. The input voltage differential (1.14 VDC vs. 1.2 VDC) is within typical control circuit tolerances and does not affect substitution viability. Selection between these parts should be based on availability, lead time, and cost considerations, as electrical and mechanical compatibility is fully established. Both devices are suitable for direct socket replacement without design modification.

Frequently Asked Questions (FAQ)

Q: Can the LAA110 replace the AQW210 in an existing PCB design? A: Yes. Both parts share identical 8-DIP (0.300", 7.62mm) package geometry, PC Pin termination, and electrical specifications. No PCB layout changes are required.

Q: Are there differences in input voltage requirements? A: The AQW210 specifies 1.14 VDC input, while the LAA110 specifies 1.2 VDC input. This 0.06 VDC difference is within standard control circuit tolerances and does not affect practical substitution.

Q: Do both parts support AC and DC load switching? A: Yes. Both the AQW210 and LAA110 are rated for AC and DC output switching across the 0–350 V load voltage range at 120 mA maximum current.

Q: What is the significance of the on-state resistance specification? A: Both parts specify a maximum on-state resistance of 35 Ohms. This parameter determines voltage drop across the relay during conduction and is critical for power dissipation calculations in the load circuit.

Q: Are there compliance or certification differences? A: No. Both parts are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements for industrial and commercial applications.

Q: What does SPST-NO (1 Form A) x 2 configuration mean? A: This indicates two independent single-pole, single-throw normally-open relay channels within a single 8-DIP package. Each channel can switch one load independently.
