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

Part Overview

The PS7113L-2A-A is a solid-state relay (SSR) manufactured by CEL, configured as a SPST-NO (1 Form A) dual-channel device rated for 350 mA load current at 0-100 V output. This product is classified as obsolete, making identification of suitable substitutes necessary for new designs and ongoing maintenance. Equivalent parts must maintain compatible electrical specifications and identical surface-mount packaging to ensure drop-in replacement capability.

Key Parameters

Substitute Part Grouping Explanation

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

Required Compatibility Criteria:

• Circuit configuration: SPST-NO (1 Form A) x 2
• Mounting type: Surface Mount
• Package type: 8-SMD (0.300", 7.62mm) with Gull Wing termination
• Input voltage: 1.2 VDC
• Output type: AC and DC support
• Load voltage range: must accommodate 0-100 V operation
• Load current: must support or exceed 350 mA

The PAA132S from IXYS Integrated Circuits Division satisfies all mandatory substitution criteria. While the PAA132S offers reduced maximum load voltage (0-60 V) and increased load current capability (600 mA) with improved on-state resistance (1 Ohm), it maintains identical circuit configuration, package geometry, and input voltage specifications. This device qualifies as a direct electrical and mechanical substitute where load voltage does not exceed 60 V.

Parameter Comparison

Engineering Selection Recommendations

The PAA132S qualifies as a suitable substitute for the PS7113L-2A-A based on the following:

1. Product Status: The original PS7113L-2A-A is classified as obsolete, establishing immediate necessity for substitution in active designs. The PAA132S maintains active product status with established supply chain availability.

2. Regulatory Compliance: The PAA132S is certified as ROHS3 compliant, meeting modern regulatory requirements for electronic components. The original device status lacks this certification detail.

3. Electrical Compatibility: Both devices operate with identical 1.2 VDC input voltage and support dual SPST-NO circuit topology with AC/DC output capability. The PAA132S delivers superior electrical performance through reduced on-state resistance (1 Ohm versus 2.5 Ohms) and higher load current capacity (600 mA versus 350 mA).

4. Physical Substitutability: Identical 8-SMD (0.300", 7.62mm) package geometry with gull wing termination enables direct board-level replacement without layout modification.

Substitution Constraint: The PAA132S maximum load voltage rating of 60 V restricts its use to applications where load voltage does not exceed this threshold. Applications requiring sustained operation above 60 V require alternative sourcing strategies.

Frequently Asked Questions (FAQ)

Q: Can the PAA132S directly replace the PS7113L-2A-A on existing PCBs?

A: Yes, the PAA132S provides identical pinout and package footprint (8-SMD, 0.300" pitch). No board redesign is required for mechanical substitution. Electrical compatibility is confirmed provided load voltage does not exceed 60 V.

Q: What is the significance of the load voltage difference between these devices?

A: The PS7113L-2A-A supports load voltages from 0-100 V, while the PAA132S operates over 0-60 V. This represents the primary electrical constraint governing substitution eligibility. Designs operating exclusively within the 0-60 V range utilize the PAA132S without derating.

Q: How does the on-state resistance difference affect circuit performance?

A: The PAA132S exhibits 1 Ohm maximum on-state resistance compared to 2.5 Ohms in the PS7113L-2A-A. This improvement reduces conduction losses and heat dissipation, benefiting thermal management in power-switching applications.

Q: Does the higher load current rating of the PAA132S affect substitution compatibility?

A: The PAA132S 600 mA rating exceeds the PS7113L-2A-A 350 mA specification. This represents improved headroom for current handling and does not introduce substitution constraints. Applications designed for 350 mA operate within the PAA132S rating with margin.

Q: What regulatory certifications should guide component selection?

A: The PAA132S ROHS3 compliance satisfies current regulatory requirements for commercial and industrial applications. Designs subject to specific regulatory frameworks should confirm certification alignment with applicable standards.
