PS7160-1A-A Equivalent & Substitute Parts

Part Overview

The PS7160-1A-A is a solid-state relay (SSR) with SPST-NO (Single-Pole Single-Throw Normally Open) configuration manufactured by CEL. This component is rated for 90 mA load current across 0-600V AC/DC applications with 1.2VDC input trigger voltage and operates in a 6-DIP package format. The product is classified as obsolete, making identification of functionally equivalent active alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS7160-1A-A requires strict compliance with the following electrical and mechanical parameters:

Critical Matching Parameters:

• Circuit Configuration: SPST-NO (1 Form A)
• Output Type: AC and DC capability
• Load Voltage Range: 0-600V minimum
• Package / Case: 6-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole with PC Pin termination

Compatible Load Current Range: The PS7160-1A-A is rated for 90 mA. Substitute parts must support minimum 90 mA operation to maintain full design margin. Parts exceeding this rating provide enhanced headroom for peak transient conditions.

Input Voltage Compatibility: The PS7160-1A-A operates with 1.2VDC input trigger. Substitute parts with input voltages between 1.14VDC and 1.37VDC remain compatible with standard driver circuit designs.

On-State Resistance: The PS7160-1A-A specifies maximum 50 Ohms. Substitute parts with equal or lower on-state resistance maintain equivalent power dissipation characteristics.

All three identified substitutes meet these core parameters and maintain identical physical form factor and circuit topology.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection - PLA193 (IXYS Integrated Circuits Division): The PLA193 provides direct parameter matching with the PS7160-1A-A across all critical electrical specifications: identical 1.2VDC input voltage, 100 mA load current (exceeding the original 90 mA), and matching 50 Ohm maximum on-state resistance. The part carries ROHS3 compliance and REACH unaffected status, providing regulatory advantage over the original obsolete component. Active product status ensures long-term availability.

Secondary Selection - CT138 (Coto Technology): The CT138 meets load voltage, package, and circuit configuration requirements with 80 mA load current capacity. While 10 mA below the original 90 mA rating, this component operates within acceptable margin for most applications. On-state resistance of 60 Ohms remains within acceptable power dissipation limits. ROHS3 compliance and REACH unaffected status are advantages. MSL rating of 2 requires standard moisture control practices.

Tertiary Selection - AQV216 (Panasonic Electric Works): The AQV216 provides lowest input voltage at 1.14VDC and supplies active product status with ROHS3 compliance. However, 50 mA load current rating falls significantly below the original 90 mA specification and the 120 Ohm maximum on-state resistance doubles the power dissipation requirement. This component is suitable only for applications where load current remains well below 50 mA.

Frequently Asked Questions (FAQ)

Q: Can the AQV216 directly replace the PS7160-1A-A in all applications?

A: The AQV216 shares identical package, mounting, and circuit topology with the PS7160-1A-A. However, the 50 mA load current rating is substantially lower than the original 90 mA specification. Use is limited to applications confirmed to operate at or below 50 mA load current. The 120 Ohm on-state resistance also increases power dissipation by 240% relative to the original component.

Q: What is the advantage of the PLA193 over the original PS7160-1A-A?

A: The PLA193 maintains electrical parameter equivalence to the PS7160-1A-A while providing active product status, ensuring continued availability. It carries ROHS3 compliance and REACH unaffected designation, providing regulatory advantages for new system designs. The 100 mA load current rating provides additional design margin beyond the original 90 mA specification.

Q: Are all three substitutes mechanically interchangeable?

A: Yes. All three substitute parts share the identical 6-DIP (0.300", 7.62mm) package format with PC Pin termination and Through Hole mounting. Direct socket replacement is mechanically feasible without circuit board redesign.

Q: How does on-state resistance affect component selection?

A: On-state resistance directly determines power dissipation in the relay output stage. The PS7160-1A-A and PLA193 both specify 50 Ohms maximum. The CT138 at 60 Ohms and AQV216 at 120 Ohms increase dissipation by 20% and 240% respectively at maximum rated load current. Applications with significant load current density or thermal constraints should prioritize lower on-state resistance ratings.

Q: Can input voltage differences affect circuit compatibility?

A: The PS7160-1A-A requires 1.2VDC input trigger. All substitute parts operate within compatible input voltage ranges: AQV216 at 1.14VDC, CT138 at 1.37VDC, and PLA193 at 1.2VDC. Standard TTL/CMOS driver circuits designed for the original 1.2VDC specification remain compatible with all substitutes without circuit modification.
