PS7113L-2A-E3-A Solid State Relay: Equivalent & Substitute Parts

Part Overview

The PS7113L-2A-E3-A is a surface mount solid state relay (SSR) manufactured by CEL, configured as a dual SPST-NO (1 Form A) relay with 350 mA load current capacity and 0–100 V load voltage range. The device operates with 1.2 VDC input control voltage and features a maximum on-state resistance of 2.5 Ohms. This part is classified as obsolete, making identification of equivalent substitute components essential for ongoing system support and new design implementations.

The PS7113L-2A-E3-A is packaged in an 8-SMD (0.300", 7.62mm) gull wing termination style suitable for automated surface mount assembly. With 8,604 units currently in stock, this part remains available despite its obsolete status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS7113L-2A-E3-A is determined by strict alignment of the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration: SPST-NO (1 Form A) x 2
• Package / Case: 8-SMD (0.300", 7.62mm)
• Termination style: Gull Wing
• Input voltage: 1.2 VDC
• Output type: AC, DC
• Mounting type: Surface Mount

Allowable Parameter Variations: Substitute parts may exceed the original specifications in load current capacity and load voltage range, provided they do not fall below the PS7113L-2A-E3-A requirements. On-state resistance may be lower (improved performance) but must maintain electrical compatibility within the application circuit.

The PAA132S from IXYS Integrated Circuits Division meets all mandatory compatibility parameters and is classified as an active product, providing long-term availability assurance.

Engineering Selection Recommendations

Primary Substitute: PAA132S

The PAA132S is the qualified substitute for the PS7113L-2A-E3-A based on the following engineering criteria:

1. Functional Equivalence: Both devices share identical circuit configuration (dual SPST-NO), input voltage (1.2 VDC), output type (AC/DC), package geometry (8-SMD 0.300"), and termination style (gull wing).

2. Product Status Advantage: The PAA132S is classified as active, ensuring continued availability and manufacturing support. The PS7113L-2A-E3-A is obsolete, necessitating substitution for new designs and long-term system maintenance.

3. Compliance and Certification: The PAA132S is ROHS3 compliant, meeting current environmental and regulatory requirements. Both parts maintain REACH Unaffected status and EAR99 ECCN classification.

4. Performance Characteristics: The PAA132S provides superior on-state resistance (1 Ohm versus 2.5 Ohms maximum) and higher load current capacity (600 mA versus 350 mA). These improvements enhance system reliability and thermal performance.

5. Load Voltage Consideration: The PAA132S is rated for 0–60 V load voltage, compared to the PS7113L-2A-E3-A rating of 0–100 V. Applications requiring load voltages exceeding 60 V require alternative evaluation.

Inventory Status: PAA132S has 2,940 units in stock, providing immediate availability for procurement.

Frequently Asked Questions (FAQ)

Q1: Can the PAA132S directly replace the PS7113L-2A-E3-A in existing circuit boards?

A: Yes, for applications with load voltages not exceeding 60 V. The PAA132S shares identical package geometry (8-SMD 0.300"), termination style (gull wing), input voltage (1.2 VDC), and circuit configuration (dual SPST-NO). No PCB layout modifications are required. Applications requiring load voltages between 60 V and 100 V require alternative component evaluation.

Q2: What is the significance of the load voltage difference between these parts?

A: The PS7113L-2A-E3-A supports load voltages from 0–100 V, while the PAA132S is rated 0–60 V. This parameter defines the maximum voltage that can be switched across the relay contacts. Selection depends on the specific application voltage requirements. If your application operates at or below 60 V, the PAA132S is fully compatible. Higher voltage applications require components rated for the full 100 V range.

Q3: Why is on-state resistance important in SSR selection?

A: On-state resistance directly affects power dissipation and heat generation during relay operation. The PAA132S maximum on-state resistance of 1 Ohm is superior to the PS7113L-2A-E3-A specification of 2.5 Ohms. Lower resistance reduces thermal stress on the component and improves overall system efficiency, particularly in high-current or continuous-duty applications.

Q4: Does the higher load current rating of the PAA132S (600 mA vs. 350 mA) affect compatibility?

A: No. Higher current capacity is a performance enhancement that does not compromise compatibility. The PAA132S can safely handle the 350 mA load current requirement of the original PS7113L-2A-E3-A application. This additional capacity provides design margin and supports potential future application upgrades without component replacement.

Q5: Are there any environmental or compliance differences between these parts?

A: The PAA132S is ROHS3 compliant, meeting current environmental regulations. The PS7113L-2A-E3-A compliance status is not specified in available documentation. Both parts maintain REACH Unaffected status and EAR99 ECCN classification. For new designs and applications subject to environmental compliance requirements, the PAA132S is the preferred selection.

Q6: What is the packaging difference between these parts?

A: The PS7113L-2A-E3-A is supplied in standard packaging (not specified). The PAA132S is supplied in tube packaging. Both parts use identical 8-SMD (0.300", 7.62mm) component packages suitable for surface mount assembly. Tube packaging is standard for active production components and does not affect electrical or mechanical compatibility.
