PS7113L-1A Solid State Relay SPST-NO Equivalent & Substitute Parts

Part Overview

The PS7113L-1A is a solid state relay (SSR) manufactured by CEL, configured as a SPST-NO (Single Pole Single Throw - Normally Open) device with 1 Form A circuit topology. This component operates with a 1.2VDC input signal and supports load voltages from 0V to 100V at a maximum load current of 350mA. The device is packaged in a 6-SMD (0.300", 7.62mm) surface mount configuration with gull wing termination.

The PS7113L-1A is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this relay topology.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS7113L-1A is determined by strict alignment of the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit Configuration: SPST-NO (1 Form A)
• Mounting Type: Surface Mount
• Package / Case: 6-SMD (0.300", 7.62mm)
• Termination Style: Gull Wing
• Output Type: AC, DC capability

Electrical Performance Parameters:

• Voltage - Load: 0V ~ 100V (or compatible range)
• Load Current: 350mA (or higher capacity)
• On-State Resistance: 2.5 Ohms (or lower)
• Voltage - Input: Compatible signal voltage

All substitute parts listed below maintain identical mechanical packaging and circuit topology. Electrical parameters are equal to or exceed the PS7113L-1A specifications, ensuring functional compatibility in existing designs.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes for Full Compatibility:

AQV255A provides the closest functional match to PS7113L-1A. Both devices support 0V ~ 100V load voltage range, 350mA load current, and 2.5 Ohms maximum on-state resistance. AQV255A is manufactured by Panasonic Electric Works with active product status and ROHS3 compliance, providing regulatory advantage over the obsolete PS7113L-1A.

AQV215A is compatible for applications requiring 0V ~ 100V load voltage support. Load current capacity is 320mA, which is marginally lower than the PS7113L-1A specification of 350mA. On-state resistance is 4 Ohms, higher than the original part. This substitute is suitable for designs with reduced current requirements.

Secondary Substitutes for Load Voltage ≤ 60V Applications:

AQV212A supports 0V ~ 60V load voltage with 550mA load current and 2.5 Ohms on-state resistance. Input voltage requirement is 1.14VDC. This substitute is applicable only to designs where maximum load voltage does not exceed 60V.

AQV202A and AQV252A both support 0V ~ 60V load voltage with 400mA load current and 1.4 Ohms on-state resistance. Both are suitable for applications limited to 60V maximum load voltage. AQV252A carries RoHS compliance designation.

AQV102A provides 600mA load current capacity but supports only DC output type and 0V ~ 60V load voltage. This substitute is restricted to DC-only applications with maximum load voltage of 60V.

Regulatory Compliance Consideration:

All substitute parts listed are RoHS compliant, providing environmental and regulatory advantage over the RoHS non-compliant PS7113L-1A. Selection should prioritize AQV255A for direct replacement in new designs or redesigns requiring regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can AQV255A directly replace PS7113L-1A in existing PCB designs?

A: Yes. AQV255A maintains identical mechanical packaging (6-SMD, 0.300", 7.62mm gull wing termination), circuit configuration (SPST-NO), and critical electrical parameters (0V ~ 100V load voltage, 350mA load current, 2.5 Ohms on-state resistance). No PCB layout modification is required.

Q: What is the difference between AQV215A and AQV255A?

A: Both devices support 0V ~ 100V load voltage and share identical input voltage (1.14VDC) and on-state resistance (2.5 Ohms for AQV255A, 4 Ohms for AQV215A). AQV255A provides 350mA load current matching PS7113L-1A, while AQV215A provides 320mA. AQV255A is the preferred substitute for full electrical compatibility.

Q: Why do some substitutes list only DC output type?

A: AQV102A is specified for DC output only, limiting its application to designs requiring DC switching. PS7113L-1A and most substitute parts support both AC and DC output types, providing greater application flexibility. Verify output type requirements before selecting AQV102A.

Q: Can I use AQV212A, AQV202A, or AQV252A if my application requires 100V load voltage?

A: No. These parts are rated for maximum 0V ~ 60V load voltage. Using them in applications requiring 100V load voltage exceeds component specifications and creates reliability risk. Select AQV255A or AQV215A for 100V load voltage support.

Q: What is the significance of RoHS compliance in substitute selection?

A: All substitute parts are RoHS compliant, while PS7113L-1A is RoHS non-compliant. For new designs or products subject to RoHS regulations, substitute parts provide regulatory compliance advantage. Existing designs using PS7113L-1A may continue operation, but redesigns should incorporate RoHS-compliant substitutes.

Q: Are input voltage differences between PS7113L-1A (1.2VDC) and substitutes significant?

A: Input voltage differences require circuit evaluation. PS7113L-1A requires 1.2VDC input. AQV212A, AQV215A, AQV252A, and AQV255A require 1.14VDC input (compatible with 1.2VDC signal). AQV102A and AQV202A require 2.3VDC input, necessitating driver circuit modification. Verify input signal voltage availability in your application before selection.

Q: What inventory status should influence my substitute selection?

A: All substitute parts are listed as active products with current inventory availability. AQV252A shows highest inventory (4000 Pcs), followed by AQV212A (2711 Pcs) and AQV255A (1900 Pcs). For long-term supply assurance, prioritize parts with higher inventory levels, provided electrical specifications match application requirements.
