XAA170S Equivalent & Substitute Parts

Part Overview

The XAA170S is an active solid-state relay (SSR) manufactured by IXYS Integrated Circuits Division, part of the OptoMOS® series. This component functions as a SPST-NO (Single Pole Single Throw - Normally Open) relay with dual channels in an 8-SMD surface mount package. The device is designed for AC and DC load switching applications with a maximum load voltage range of 0–350V and a load current rating of 100mA. The XAA170S maintains ROHS3 compliance and is actively produced. Identifying equivalent substitute parts becomes necessary when managing supply chain continuity, optimizing procurement costs, or addressing component availability constraints while maintaining identical electrical and mechanical performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the XAA170S is determined by strict adherence to the following critical parameters:

Mandatory Matching Criteria:

• Circuit configuration: SPST-NO (1 Form A) x 2
• Package type: 8-SMD (0.300", 7.62mm)
• Termination style: Gull Wing
• Mounting type: Surface Mount
• Load voltage range: 0V ~ 350V
• Output type: AC, DC
• RoHS compliance: ROHS3 Compliant

Allowable Parameter Variations:

• Input voltage: May differ from 1.2VDC if within component design specifications
• Load current: May exceed 100mA (higher current capability is acceptable)
• On-state resistance: May be lower than 50 Ohms (improved performance is acceptable)

The AQW210EHA from Panasonic Electric Works meets all mandatory matching criteria and demonstrates improved electrical performance characteristics within the allowable variation parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the XAA170S and AQW210EHA are active products with ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards. The AQW210EHA demonstrates superior electrical performance through lower on-state resistance (25 Ohms versus 50 Ohms) and higher load current capability (120mA versus 100mA), while maintaining identical package geometry, termination style, and load voltage specifications. The input voltage differential (1.14VDC versus 1.2VDC) remains within acceptable operational margins for typical control circuit implementations. Both components are manufactured using optoisolation technology and are suitable for direct substitution in applications requiring SPST-NO dual-channel solid-state relay functionality in the 0–350V load range.

Frequently Asked Questions (FAQ)

Q: Can the AQW210EHA replace the XAA170S in existing circuit designs? A: Yes. Both components share identical circuit configuration (SPST-NO x 2), package type (8-SMD), termination style (Gull Wing), and load voltage range (0–350V). The AQW210EHA provides improved performance characteristics with lower on-state resistance and higher current capability.

Q: Are there any PCB layout modifications required when substituting the AQW210EHA for the XAA170S? A: No. Both components use the same 8-SMD (0.300", 7.62mm) package with Gull Wing termination. PCB footprints are identical, and no layout changes are necessary.

Q: What is the significance of the input voltage difference between these components? A: The XAA170S requires 1.2VDC input, while the AQW210EHA requires 1.14VDC input. This 0.06VDC difference is negligible in typical control circuit applications and does not affect substitution compatibility.

Q: Do both components support AC and DC load switching? A: Yes. Both the XAA170S and AQW210EHA are rated for AC and DC output switching across the 0–350V load voltage range.

Q: Are there any compliance or certification differences between these parts? A: Both components are ROHS3 compliant, REACH unaffected, and actively produced. No compliance barriers exist for substitution.

Q: What is the practical advantage of the AQW210EHA's lower on-state resistance? A: Lower on-state resistance (25 Ohms versus 50 Ohms) results in reduced power dissipation and heat generation during load switching, improving overall circuit efficiency and thermal performance.
