PLA134S Equivalent & Substitute Parts

Part Overview

The PLA134S is a solid-state relay (SSR) manufactured by IXYS Integrated Circuits Division, configured as a SPST-NO (Single Pole Single Throw - Normally Open) switch. This component operates with a 1.2VDC input signal and supports load voltages from 0V to 100V with a maximum load current of 350mA. The device is packaged in a 6-SMD surface mount configuration with gull wing termination.

The PLA134S has reached obsolete product status. Locating equivalent or substitute components is necessary to support ongoing maintenance, repair, and redesign activities for systems currently utilizing this relay.

Key Parameters

Substitute Part Grouping Explanation

The LCA701S qualifies as a direct substitute for the PLA134S based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Circuit configuration: Both are SPST-NO (1 Form A) relays
• Input voltage: Both operate at 1.2VDC
• Load voltage range: Both support 0V to 100V
• Output type: Both handle AC and DC loads
• Package / Case: Both use 6-SMD (0.300", 7.62mm)
• Termination style: Both feature gull wing termination
• Mounting type: Both are surface mount
• RoHS and REACH compliance: Both meet ROHS3 and REACH Unaffected standards
• Moisture sensitivity: Both rated MSL 1 (Unlimited)

Enhanced Capability: The LCA701S provides increased load current capacity (1.5A versus 350mA) and reduced on-state resistance (300mOhms versus 3 Ohms), making it suitable for applications requiring the PLA134S specifications while offering improved performance headroom.

Parameter Comparison

Engineering Selection Recommendations

The LCA701S is the manufacturer-recommended substitute for the obsolete PLA134S. Both components are manufactured by IXYS Integrated Circuits Division within the OptoMOS® solid-state relay family and maintain identical electrical specifications for input voltage, load voltage range, and circuit configuration.

The LCA701S carries active product status, ensuring ongoing availability and supply chain support. Both parts meet ROHS3 compliance and REACH unaffected requirements, maintaining regulatory alignment for new designs and legacy system support.

The LCA701S provides enhanced electrical performance with increased load current capacity and reduced on-state resistance, making it suitable for direct substitution in applications currently specified for the PLA134S without requiring circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the LCA701S be used as a direct replacement for the PLA134S in existing designs?

A: Yes. The LCA701S maintains identical input voltage (1.2VDC), load voltage range (0V to 100V), circuit configuration (SPST-NO), and package specifications (6-SMD with gull wing termination). The enhanced load current and reduced on-state resistance of the LCA701S are backward compatible with PLA134S applications.

Q: What is the primary difference between the PLA134S and LCA701S?

A: The LCA701S provides increased load current capacity (1.5A versus 350mA) and lower on-state resistance (300mOhms versus 3 Ohms). The LCA701S also maintains active product status, whereas the PLA134S is obsolete.

Q: Are the package dimensions identical between these parts?

A: Yes. Both the PLA134S and LCA701S use the 6-SMD (0.300", 7.62mm) package with gull wing termination, ensuring identical PCB footprint and mounting compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the PLA134S and LCA701S are ROHS3 compliant and REACH unaffected, maintaining equivalent regulatory status for applications requiring these certifications.

Q: Why is the PLA134S listed as obsolete?

A: The PLA134S has reached end-of-life status within the IXYS product portfolio. The LCA701S represents the active equivalent within the OptoMOS® relay family, offering improved electrical performance and continued manufacturing support.
