LAA110L Solid State Relay - Equivalent & Substitute Parts

Part Overview

The LAA110L is an active solid state relay (SSR) manufactured by IXYS Integrated Circuits Division, configured as a SPST-NO (Single Pole Single Throw - Normally Open) relay with dual channels in an 8-DIP package. This component is designed for AC and DC load switching applications with a maximum load voltage of 350V and 120mA current capacity. The part is ROHS3 compliant and currently in active production status with 4,669 units in stock.

Equivalent and substitute parts are identified when they maintain identical or compatible electrical and mechanical specifications, allowing direct replacement in circuit designs without functional degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LAA110L is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) x 2 dual-channel configuration
• Load Voltage Range: Must support 0V to 350V operation
• Load Current: Must support minimum 120mA
• Package Type: Must be 8-DIP (0.300", 7.62mm) for mechanical compatibility
• Mounting and Termination: Must use Through Hole mounting with PC Pin termination
• Output Type: Must support both AC and DC loads

The AQW210HL from Panasonic Electric Works meets all substitution criteria, maintaining identical circuit configuration, load specifications, package dimensions, and mounting characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the LAA110L and AQW210HL are active production components with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and use.

The AQW210HL presents operational advantages through lower input voltage requirement (1.14VDC versus 1.2VDC) and reduced on-state resistance (25 Ohms versus 35 Ohms maximum), resulting in lower power dissipation and improved switching efficiency. These characteristics make the AQW210HL suitable for applications with tighter power budgets or thermal constraints.

Selection between these parts should be based on availability, lead time, cost considerations, and existing supply chain relationships, as both components satisfy identical electrical and mechanical requirements for direct substitution in 8-DIP through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can the AQW210HL directly replace the LAA110L in existing PCB designs?

A: Yes. Both components use identical 8-DIP (0.300", 7.62mm) package dimensions with PC Pin termination, enabling direct pin-for-pin replacement without PCB modification.

Q: Are there differences in switching performance between these parts?

A: Both parts maintain identical load voltage range (0V to 350V), load current (120mA), and dual SPST-NO channel configuration. The AQW210HL operates at lower input voltage (1.14VDC versus 1.2VDC) and exhibits lower on-state resistance (25 Ohms maximum versus 35 Ohms maximum).

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

A: Yes. Both the LAA110L and AQW210HL are rated for AC and DC output operation across the full 0V to 350V load voltage range.

Q: What is the significance of the different series designations (OptoMOS® versus PhotoMOS™)?

A: These designations identify the manufacturer's proprietary technology families. OptoMOS® is IXYS technology; PhotoMOS™ is Panasonic technology. Both are solid state relay implementations meeting identical electrical specifications for this application.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the LAA110L and AQW210HL are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component use in regulated markets.

Q: What packaging options are available for these parts?

A: Both components are supplied in Tube packaging for the 8-DIP configuration specified.
