PS710AL-1A Solid State Relay: Equivalent & Substitute Parts

Part Overview

The PS710AL-1A is a Surface Mount Solid State Relay (SSR) manufactured by CEL, configured as a SPST-NO (Single Pole Single Throw - Normally Open) relay with 1 Form A circuit. This component is designed for switching applications requiring 1.8A load current at 0-60V DC/AC output with a 1.2VDC input signal. The device features a 6-SMD Gull Wing package with 200 mOhms maximum on-state resistance.

The PS710AL-1A is classified as obsolete. Locating equivalent or substitute components is necessary to support ongoing maintenance, repair, and new design requirements where this part is specified or where inventory depletion necessitates alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS710AL-1A is determined by strict alignment of the following critical parameters:

Circuit Configuration: Both the main part and substitute must be SPST-NO (1 Form A) to maintain identical switching functionality.

Package and Mounting: The 6-SMD (0.300", 7.62mm) Gull Wing surface mount package must be preserved to ensure PCB compatibility and assembly process alignment.

Input Voltage: The substitute must accept the 1.2VDC input signal specified for the PS710AL-1A.

Load Voltage Range: The substitute's maximum load voltage rating must accommodate the 0-60V operating range.

Load Current Capacity: The substitute must support the 1.8A load current requirement.

Output Type: The substitute must support both AC and DC output switching, or at minimum DC output for applications using DC loads.

The AQV101A from Panasonic Electric Works meets the circuit configuration, package, and mounting requirements. However, substitution analysis reveals parameter constraints that must be evaluated for specific applications.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The PS710AL-1A is obsolete, making the AQV101A the only identified substitute with active manufacturing status and current availability.

Compliance and Standards: The AQV101A is RoHS Compliant, meeting modern environmental and regulatory requirements. The original PS710AL-1A is RoHS non-compliant. For new designs or applications subject to RoHS requirements, the AQV101A provides compliance alignment.

Application-Specific Constraints: The AQV101A exhibits three parameter deviations from the PS710AL-1A:

1. Load current capacity is reduced from 1.8A to 700mA
2. Maximum load voltage is reduced from 60V to 40V
3. Input voltage requirement increases from 1.2VDC to 2.3VDC

These deviations require evaluation against specific application requirements. The AQV101A is suitable only for applications where load current does not exceed 700mA, load voltage remains within 0-40V, and input signal voltage is 2.3VDC or higher.

Output Type Limitation: The AQV101A supports DC output only, whereas the PS710AL-1A supports both AC and DC. Applications requiring AC output switching cannot use the AQV101A as a direct substitute.

Frequently Asked Questions (FAQ)

Q: Can the AQV101A directly replace the PS710AL-1A in all applications?

A: No. The AQV101A has reduced load current capacity (700mA vs. 1.8A), reduced maximum load voltage (40V vs. 60V), higher input voltage requirement (2.3VDC vs. 1.2VDC), and supports DC output only. Direct substitution is valid only for applications operating within these reduced parameter ranges.

Q: What is the physical compatibility between these parts?

A: Both parts use identical 6-SMD (0.300", 7.62mm) Gull Wing surface mount packages. PCB footprints and assembly processes are compatible. No mechanical redesign is required for package substitution.

Q: Why does the AQV101A require higher input voltage?

A: The AQV101A is a PhotoMOS™ device with different input circuit design. The 2.3VDC input requirement is a characteristic of this technology. Existing 1.2VDC input signals must be verified for compatibility or redesigned to meet the 2.3VDC threshold.

Q: Is the AQV101A suitable for AC load switching?

A: No. The AQV101A is rated for DC output only. Applications requiring AC load switching cannot use this substitute. The PS710AL-1A supported both AC and DC output types.

Q: What is the impact of higher on-state resistance?

A: The AQV101A has 500 mOhms maximum on-state resistance compared to 200 mOhms for the PS710AL-1A. This results in higher power dissipation and voltage drop across the relay during conduction. Applications sensitive to power loss or thermal management must account for this 2.5x increase in resistance.

Q: Are there inventory considerations for substitution?

A: The PS710AL-1A has 2400 pieces in stock as new original inventory. The AQV101A has 7000 pieces available. For long-term production or maintenance requirements, the AQV101A offers superior availability as an active product.

Q: What compliance advantages does the AQV101A provide?

A: The AQV101A is RoHS Compliant and has no moisture sensitivity level restriction. The PS710AL-1A is RoHS non-compliant and carries MSL 1 (Unlimited) classification. For applications subject to RoHS directives or environmental regulations, the AQV101A meets current standards.
