PLA132S Solid State Relay - Equivalent & Substitute Parts

Part Overview

The PLA132S is an active SPST-NO (1 Form A) solid state relay manufactured by IXYS Integrated Circuits Division, operating in the 0-60V load voltage range with 600mA maximum load current. This OptoMOS® series component is designed for surface mount applications in 6-SMD packaging and maintains ROHS3 compliance with unlimited moisture sensitivity rating.

Substitute parts are identified based on matching circuit topology (SPST-NO), package form factor (6-SMD 0.300"), load voltage range (0-60V), and output type (AC/DC). The substitute relays listed provide equivalent or enhanced electrical performance within the same mechanical envelope.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PLA132S is determined by the following mandatory parameters:

• Circuit Configuration: SPST-NO (1 Form A) topology required
• Package Form Factor: 6-SMD (0.300", 7.62mm) with Gull Wing termination
• Load Voltage Range: 0V ~ 60V maximum
• Output Type: AC/DC capable
• Mounting Type: Surface Mount
• Compliance: ROHS3 Compliant, MSL 1

The three substitute parts listed (ASSR-1511-301E, ASSR-1511-501E, ASSR-1611-301E) meet all mandatory substitution criteria. These Broadcom Limited ASSR series relays maintain identical package geometry, load voltage specifications, and compliance certifications. Differences in load current rating and on-state resistance represent enhanced electrical performance characteristics within the same mechanical and electrical envelope.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment with the original PLA132S specification.

ASSR-1511-301E and ASSR-1511-501E provide 1A load current capability with 500mOhm on-state resistance. These parts are functionally equivalent for applications requiring up to 1A switching capacity. The ASSR-1511-501E offers expanded packaging availability (Cut Tape & Digi-Reel) compared to tube packaging of the ASSR-1511-301E.

ASSR-1611-301E provides enhanced performance with 2.5A load current capability and 100mOhm on-state resistance, suitable for applications requiring higher current switching or lower conduction losses within the same 0-60V load voltage envelope.

All substitutes maintain identical input voltage tolerance (1.3VDC vs. 1.2VDC original specification) and preserve the 6-SMD gull wing package geometry for direct PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can ASSR-1511-301E directly replace PLA132S in existing designs?

A: Yes. Both components share identical circuit topology (SPST-NO), package form factor (6-SMD 0.300"), load voltage range (0-60V), and termination style (Gull Wing). The ASSR-1511-301E provides higher load current (1A vs. 600mA) and lower on-state resistance (500mOhm vs. 1 Ohm), making it functionally compatible for direct substitution.

Q: What is the difference between ASSR-1511-301E and ASSR-1511-501E?

A: Both parts are electrically identical with 1A load current and 500mOhm on-state resistance. The primary difference is packaging format: ASSR-1511-301E is supplied in Tube packaging, while ASSR-1511-501E is available in Cut Tape and Digi-Reel formats. Selection depends on procurement and assembly requirements.

Q: When should ASSR-1611-301E be selected over ASSR-1511-301E?

A: ASSR-1611-301E is selected for applications requiring higher load current (2.5A vs. 1A) or lower conduction losses (100mOhm vs. 500mOhm on-state resistance). Both maintain the same 0-60V load voltage range and 6-SMD package geometry.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. PLA132S and all three substitute parts (ASSR-1511-301E, ASSR-1511-501E, ASSR-1611-301E) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Will PCB layout require modification when substituting these parts?

A: No. All parts use identical 6-SMD (0.300", 7.62mm) package with Gull Wing termination, ensuring direct footprint compatibility without PCB redesign.
