Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS7113L-2A-E4-A is determined by the following critical parameters that must be maintained or exceeded:

Mandatory Compatibility Parameters:

• Circuit configuration: SPST-NO (1 Form A) x 2 dual-channel architecture
• Mounting type: Surface Mount
• Package type: 8-SMD (0.300", 7.62mm) with Gull Wing termination
• Input voltage: 1.2 VDC control signal
• Output type: AC and DC switching capability

Performance Parameters (Substitutes must meet or exceed):

• Load current rating: minimum 350 mA
• Load voltage range: minimum 0-100 V capability
• On-state resistance: maximum 2.5 Ohms

The PAA132S from IXYS Integrated Circuits Division satisfies all mandatory compatibility parameters and exceeds performance specifications, making it a direct functional substitute for the obsolete PS7113L-2A-E4-A.

Parameter Comparison

Engineering Selection Recommendations

The PAA132S is the identified substitute for the obsolete PS7113L-2A-E4-A based on the following engineering criteria:

Functional Equivalence: Both components share identical circuit configuration (SPST-NO x 2), input voltage (1.2 VDC), output type (AC/DC), package geometry (8-SMD 0.300"), and termination style (Gull Wing). These parameters ensure direct functional replacement in existing PCB layouts without modification.

Performance Superiority: The PAA132S exceeds the load current specification (600 mA vs. 350 mA) and on-state resistance specification (1 Ohm vs. 2.5 Ohms maximum), providing improved performance margins in switching applications.

Load Voltage Consideration: The PAA132S is rated for 0-60 V load voltage, compared to the PS7113L-2A-E4-A rated for 0-100 V. Applications requiring load voltages above 60 V cannot use the PAA132S as a direct substitute.

Compliance and Availability: The PAA132S holds active product status with ROHS3 compliance and REACH unaffected designation, ensuring long-term availability and regulatory compliance. Both components share identical ECCN (EAR99) and MSL (1) classifications.

Inventory Status: The PAA132S is available in production quantities (2940 Pcs in stock) compared to the obsolete PS7113L-2A-E4-A, supporting both new designs and legacy system support.

Frequently Asked Questions (FAQ)

Q: Can the PAA132S replace the PS7113L-2A-E4-A in all applications?

A: The PAA132S is functionally equivalent for applications where the load voltage does not exceed 60 V. The PS7113L-2A-E4-A is rated for 0-100 V load voltage. If your application requires switching voltages above 60 V, the PAA132S is not suitable as a direct substitute.

Q: Are the package dimensions identical between these two parts?

A: Yes. Both the PS7113L-2A-E4-A and PAA132S use the 8-SMD (0.300", 7.62mm) package with Gull Wing termination. No PCB layout modifications are required for substitution.

Q: What is the input control voltage requirement for both parts?

A: Both components require 1.2 VDC input control voltage. Control circuit design remains unchanged when substituting the PAA132S for the PS7113L-2A-E4-A.

Q: Does the PAA132S support both AC and DC load switching?

A: Yes. The PAA132S is rated for AC and DC output type, identical to the PS7113L-2A-E4-A. Both components can switch AC or DC loads within their respective voltage and current ratings.

Q: What is the significance of the improved on-state resistance in the PAA132S?

A: The PAA132S on-state resistance is 1 Ohm maximum, compared to 2.5 Ohms maximum for the PS7113L-2A-E4-A. Lower on-state resistance reduces power dissipation and heat generation during switching operations, improving overall system efficiency.

Q: Are there compliance differences between the two parts?

A: The PAA132S is ROHS3 compliant, while the PS7113L-2A-E4-A compliance status is not specified. Both components are REACH unaffected and share the same ECCN (EAR99) classification. The PAA132S provides enhanced regulatory compliance for new designs.

Q: What is the moisture sensitivity level for both components?

A: Both the PS7113L-2A-E4-A and PAA132S have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Can the PAA132S handle higher load currents than the PS7113L-2A-E4-A?

A: Yes. The PAA132S is rated for 600 mA load current, compared to 350 mA for the PS7113L-2A-E4-A. This provides additional current capacity margin for applications requiring higher switching currents within the voltage limitations.
