PLA110L Solid State Relay - Equivalent & Substitute Parts

Part Overview

The PLA110L is an active SPST-NO (Single Pole Single Throw - Normally Open) solid state relay manufactured by IXYS Integrated Circuits Division. It operates as a 1 Form A relay with through-hole 6-DIP packaging and supports both AC and DC load switching. The device is rated for 150 mA load current across 0-400V, with a maximum on-state resistance of 25 Ohms and 1.2VDC input voltage requirement. This component is ROHS3 compliant and carries an MSL rating of 1 (Unlimited). Finding equivalent substitute parts may be necessary due to inventory constraints, supply chain disruptions, or design optimization requirements while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PLA110L is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching topology
• Package / Case: Must be 6-DIP (0.300", 7.62mm) to ensure PCB compatibility and pin alignment
• Mounting Type: Must be Through Hole to match assembly requirements
• Termination Style: Must be PC Pin for direct socket compatibility
• Output Type: Must support both AC and DC operation
• Load Current: Substitute must support minimum 130 mA (PLA110L rated at 150 mA)
• Voltage - Load: Substitute must support minimum 0-350V range (PLA110L rated at 0-400V)
• On-State Resistance: Must not exceed 25 Ohms maximum
• Input Voltage: Substitute must operate at or below 1.2VDC input requirement

The AQV210HL from Panasonic Electric Works meets all substitution criteria within these allowed parameters.

Parameter Comparison

Engineering Selection Recommendations

The AQV210HL is a direct functional substitute for the PLA110L based on the following engineering criteria:

• Both components maintain identical SPST-NO circuit configuration and 6-DIP through-hole package specifications, ensuring direct PCB compatibility without layout modifications
• Both devices are active products with current manufacturer support and availability
• Both components meet RoHS compliance requirements, with the AQV210HL carrying standard RoHS certification and the PLA110L meeting the more stringent ROHS3 standard
• The AQV210HL operates at a lower input voltage (1.14VDC vs. 1.2VDC), which is compatible with circuits designed for the PLA110L
• Load current and voltage ratings of the AQV210HL (130 mA, 0-350V) are lower than the PLA110L (150 mA, 0-400V), requiring circuit-level verification that application demands do not exceed these limits
• On-state resistance specifications are identical at 25 Ohms maximum, ensuring equivalent thermal and power dissipation characteristics
• Both components support AC and DC output operation

Selection between these parts should be based on specific application load requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the AQV210HL replace the PLA110L in any application?

A: The AQV210HL is functionally compatible with the PLA110L for applications where load current does not exceed 130 mA and load voltage does not exceed 350V. Applications requiring the full 150 mA at 400V rating of the PLA110L must use the original part or verify that the AQV210HL meets reduced specifications.

Q: Are there any PCB layout changes required when substituting the AQV210HL for the PLA110L?

A: No PCB layout changes are required. Both components use identical 6-DIP (0.300", 7.62mm) through-hole packaging with PC pin termination, allowing direct socket-to-socket replacement without modification.

Q: What is the difference between OptoMOS® and PhotoMOS™ technology?

A: Both are optically isolated solid state relay technologies from different manufacturers. The PLA110L uses IXYS OptoMOS® technology, while the AQV210HL uses Panasonic PhotoMOS™ technology. Both provide equivalent electrical performance within their specified ratings.

Q: Do both parts have the same input voltage requirement?

A: The PLA110L requires 1.2VDC input, while the AQV210HL requires 1.14VDC input. The AQV210HL operates at a lower threshold, making it compatible with circuits designed for the PLA110L.

Q: What compliance certifications apply to both parts?

A: Both components are RoHS compliant. The PLA110L meets the more stringent ROHS3 standard, while the AQV210HL meets standard RoHS requirements. Both carry EAR99 ECCN classification and fall under HTSUS code 8536.41.0030.

Q: Is the moisture sensitivity level a factor in substitution?

A: The PLA110L has an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. The AQV210HL is listed as Not Applicable for MSL, indicating it does not require moisture-controlled storage. Both parts are compatible from a moisture handling perspective.
