PLA192ESTR Equivalent & Substitute Parts

Part Overview

The PLA192ESTR is a solid-state relay (SSR) manufactured by IXYS Integrated Circuits Division, part of the OptoMOS® series. It functions as a SPST-NO (Single Pole Single Throw - Normally Open) relay with a 1 Form A circuit configuration, designed for switching applications across AC and DC loads up to 600V with a maximum load current of 150mA. The device is currently classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PLA192ESTR is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST-NO (1 Form A)
• Input voltage: 1.2VDC
• Load voltage range: 0V to 600V
• Load current capacity: 150mA
• On-state resistance: 22 Ohms maximum
• Mounting type: Surface Mount
• Package type: 6-SMD (0.300", 7.62mm)
• Termination style: Gull Wing

The PLA192STR qualifies as a direct manufacturer-recommended substitute, maintaining identical electrical specifications and mechanical form factor while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The PLA192STR is the manufacturer-recommended substitute for the obsolete PLA192ESTR. Both components maintain identical electrical and mechanical specifications, ensuring direct compatibility in existing circuit designs. The primary distinction is product status: PLA192ESTR is obsolete while PLA192STR is active, providing superior long-term availability and supply chain reliability. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current manufacturing standards. Selection of PLA192STR eliminates obsolescence risk while preserving all functional and performance characteristics of the original design.

Frequently Asked Questions (FAQ)

Q: Can PLA192STR be used as a direct replacement for PLA192ESTR in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including circuit configuration, voltage ratings, current capacity, on-state resistance, package type, and termination style. No circuit modifications are required.

Q: What is the primary advantage of switching from PLA192ESTR to PLA192STR?

A: PLA192STR is an active product with superior availability and supply chain support, whereas PLA192ESTR is obsolete. This transition eliminates long-term procurement risk and ensures continued component access.

Q: Are there any compliance or certification differences between these parts?

A: No. Both PLA192ESTR and PLA192STR maintain identical RoHS3 compliance, REACH unaffected status, and moisture sensitivity level (MSL 1 - Unlimited). Regulatory requirements are satisfied by either part.

Q: Do these parts require different PCB footprints or assembly processes?

A: No. Both components use the same 6-SMD (0.300", 7.62mm) package with gull wing termination. PCB layouts, assembly procedures, and reflow profiles remain unchanged.

Q: What load conditions are these SSR relays rated for?

A: Both parts are rated for load voltages from 0V to 600V with a maximum load current of 150mA. They support both AC and DC output switching with a maximum on-state resistance of 22 Ohms.
