PS7160L-1A Equivalent & Substitute Parts

Part Overview

The PS7160L-1A is a Solid State Relay (SSR) with SPST-NO (1 Form A) configuration, rated for 90 mA load current and 0–600 V operation. Manufactured by CEL in a 6-SMD surface mount package with gull wing termination, this component is classified as obsolete and is no longer in active production. Due to its obsolete status, identifying qualified substitutes is necessary to support legacy designs and ensure continued component availability for repair and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS7160L-1A is based on matching the following critical parameters:

• Circuit Configuration: SPST-NO (1 Form A) – ensures identical switching functionality
• Package Type: 6-SMD (0.300", 7.62mm) with gull wing termination – ensures PCB layout compatibility
• Load Voltage Range: 0 V ~ 600 V – maintains rated voltage operation
• Output Type: AC, DC – supports both signal types
• Mounting Type: Surface Mount – confirms board integration compatibility

The AQV216A from Panasonic Electric Works satisfies all these substitution criteria. While the load current rating (50 mA) is lower than the original PS7160L-1A (90 mA) and on-state resistance is higher (120 Ohms vs. 50 Ohms), these parameters are application-dependent and must be evaluated within the specific circuit context. The substitute maintains identical voltage ratings, circuit topology, and physical form factor.

Engineering Selection Recommendations

AQV216A as a Substitute for PS7160L-1A:

The AQV216A is the designated substitute for the obsolete PS7160L-1A. The Panasonic Electric Works component holds Active product status, ensuring long-term availability and supply chain continuity. The AQV216A is ROHS3 compliant and REACH unaffected, providing regulatory advantages over the non-compliant PS7160L-1A.

Both relays share identical circuit topology (SPST-NO), voltage ratings (0–600 V load), package form factor (6-SMD gull wing), and mounting configuration. The input voltage requirements are equivalent (1.14 VDC vs. 1.2 VDC), with negligible operational differences for most control circuits.

Selection between these components depends on application load current requirements. Designs operating below 50 mA can directly substitute the AQV216A without modifications. Designs requiring the full 90 mA rating of the PS7160L-1A must evaluate whether the AQV216A's 50 mA capability meets the application specification, as alternative components may be necessary for higher current applications.

Frequently Asked Questions (FAQ)

Q: Can the AQV216A directly replace the PS7160L-1A without PCB modifications?

A: Yes. Both components share identical package dimensions (6-SMD, 0.300" × 7.62mm) and gull wing termination. Direct footprint substitution is possible without PCB layout changes.

Q: What is the difference in load current ratings between these relays?

A: The PS7160L-1A supports 90 mA maximum load current, while the AQV216A supports 50 mA. The lower rating of the AQV216A is the primary electrical distinction. Application load requirements must be evaluated before substitution.

Q: Are the input control voltage requirements compatible?

A: Yes. The PS7160L-1A requires 1.2 VDC input, and the AQV216A requires 1.14 VDC input. These values are operationally equivalent for standard control circuit applications.

Q: What regulatory compliance advantages does the AQV216A offer?

A: The AQV216A is ROHS3 compliant and REACH unaffected, compared to the PS7160L-1A, which is RoHS non-compliant and REACH affected. Modern designs and supply chains increasingly enforce these environmental and regulatory standards.

Q: Is on-state resistance a critical factor in selecting between these relays?

A: On-state resistance (50 Ohms for PS7160L-1A, 120 Ohms for AQV216A) affects power dissipation and voltage drop across the relay contacts. For low-power applications, this difference may be negligible. High-current or voltage-sensitive circuits require evaluation of this parameter within the specific circuit design.

Q: Why is the PS7160L-1A classified as obsolete?

A: The PS7160L-1A is no longer in active production by CEL. The obsolete classification indicates that new inventory from the original manufacturer is not available. The AQV216A, with Active product status, provides a supported long-term alternative.
