PAA132 Solid State Relay - Equivalent & Substitute Parts

Part Overview

The PAA132 is a solid state relay (SSR) manufactured by IXYS Integrated Circuits Division, configured as a SPST-NO (Single Pole Single Throw - Normally Open) relay with dual channels in an 8-DIP package. This component is designed for switching applications requiring 600 mA load current at voltages between 0 V and 60 V, with both AC and DC output capability. The PAA132 maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, design standardization, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

The ASSR-1420-002E qualifies as a direct substitute for the PAA132 based on the following critical parameters:

• Circuit Configuration: Both parts implement SPST-NO (1 Form A) x 2 topology
• Load Voltage Range: Both support 0 V ~ 60 V operation
• Load Current: Both rated for 600 mA
• On-State Resistance: Both specify 1 Ohm maximum
• Output Type: Both support AC and DC switching
• Package: Both use 8-DIP (0.300", 7.62mm) form factor
• Mounting Type: Both are Through Hole mounted
• Termination Style: Both use PC Pin termination
• Compliance: Both are ROHS3 Compliant with MSL 1 (Unlimited)

The input voltage specification differs minimally (1.2 VDC vs. 1.3 VDC), which does not affect substitution eligibility within standard design tolerances for SSR control circuits.

Parameter Comparison

Engineering Selection Recommendations

Both the PAA132 and ASSR-1420-002E are Active status components with identical RoHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

• Availability: PAA132 inventory is 20,300 units; ASSR-1420-002E inventory is 3,560 units
• Manufacturer Preference: IXYS OptoMOS® series versus Broadcom ASSR series
• Supply Chain Requirements: Either part satisfies equivalent electrical and mechanical specifications for direct PCB substitution without design modification

Both components meet all regulatory and environmental compliance requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can ASSR-1420-002E replace PAA132 in existing designs? A: Yes. Both parts share identical circuit configuration, load voltage range, load current rating, on-state resistance, output type, and 8-DIP package dimensions. Direct substitution is electrically and mechanically compatible.

Q: What is the significance of the input voltage difference (1.2 VDC vs. 1.3 VDC)? A: The 0.1 VDC difference is within standard control circuit tolerances and does not affect substitution eligibility. Both parts operate within typical SSR input voltage specifications.

Q: Are both parts suitable for AC and DC load switching? A: Yes. Both PAA132 and ASSR-1420-002E support AC and DC output types across the 0 V to 60 V load voltage range.

Q: Do both parts require the same PCB footprint? A: Yes. Both use 8-DIP (0.300", 7.62mm) Through Hole packages with PC Pin termination, requiring identical PCB layout and mounting procedures.

Q: What compliance certifications apply to both parts? A: Both parts are ROHS3 Compliant, REACH Unaffected, with MSL 1 (Unlimited) moisture sensitivity rating, suitable for standard manufacturing and storage environments.

Q: Which part should be selected based on availability? A: Selection should be based on current inventory requirements and supply chain lead times. PAA132 has higher stock availability (20,300 units) compared to ASSR-1420-002E (3,560 units).
