PS7160L-2A-A Solid State Relay - Equivalent & Substitute Parts

Part Overview

The PS7160L-2A-A is a solid state relay (SSR) manufactured by CEL, featuring SPST-NO (1 Form A) dual configuration in an 8-SMD surface mount package. This component provides switching capability for AC and DC loads up to 600V with a 90mA load current rating and 50 ohms maximum on-state resistance. The product is obsolete, making identification of equivalent substitute parts necessary for ongoing system maintenance, redesign, and component sourcing in applications where this relay is currently specified or deployed.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PS7160L-2A-A are selected based on compatibility within the following critical parameters:

Mechanical Compatibility:

• Package / Case: 8-SMD (0.300", 7.62mm)
• Termination Style: Gull Wing
• Mounting Type: Surface Mount
• All substitutes maintain identical mechanical footprint and land pattern compatibility

Electrical Compatibility Range:

• Circuit Configuration: SPST-NO (1 Form A) x 2
• Voltage - Input: 1.2VDC (allowable variance: ±0.06VDC)
• Voltage - Load: 0 V ~ 600 V minimum (600V maximum acceptable; lower maximum voltage acceptable if application permits)
• Load Current: 90mA baseline (substitutes with ≥90mA are direct replacements; lower current substitutes require application load current verification)
• On-State Resistance: 50 ohms baseline (equal or lower values are preferred to maintain equivalent switching performance)

Three substitute parts meet these compatibility criteria and are listed below.

Parameter Comparison

Engineering Selection Recommendations

PAA193STR (IXYS Integrated Circuits Division) is the optimal substitute for direct replacement in applications requiring the full 90mA load current specification. This part maintains identical input voltage (1.2VDC), load voltage range (0-600V), and on-state resistance (50 ohms) as the PS7160L-2A-A, with enhanced load current rating (100mA). PAA193STR is active in production status and RoHS3 compliant, eliminating the sourcing constraints associated with the obsolete PS7160L-2A-A.

AQW216A (Panasonic Electric Works) provides a substitute option for applications where the 90mA load current can be reduced to 40mA. This part maintains the 600V load voltage range and 8-SMD package compatibility. Input voltage (1.14VDC) is within acceptable tolerance of the main part. On-state resistance (120 ohms) is higher than the main part and PAA193STR; applications sensitive to voltage drop across the relay must account for this parameter difference. AQW216A is active in production and ROHS3 compliant.

AQW224NA (Panasonic Electric Works) is suitable for substitution in applications operating at load voltages not exceeding 400V. This part is rated for 40mA maximum load current and includes RF output capability (AC, DC (RF)). The maximum load voltage is reduced to 400V compared to the PS7160L-2A-A 600V rating. All other mechanical and core electrical parameters align with the substitute criteria. AQW224NA is active in production and ROHS3 compliant.

All three substitute parts feature active product status with established manufacturing and supply availability, providing long-term sourcing security compared to the obsolete PS7160L-2A-A.

Frequently Asked Questions (FAQ)

Q: Can PAA193STR directly replace PS7160L-2A-A in all applications?

A: PAA193STR provides direct replacement compatibility for mechanical footprint, circuit configuration, input voltage, and load voltage specifications. The enhanced load current rating (100mA vs. 90mA) and matching on-state resistance (50 ohms) ensure equivalent performance. No circuit modifications are required for direct PCB substitution.

Q: Under what conditions can AQW216A be used as a substitute?

A: AQW216A is suitable for substitution when application load current does not exceed 40mA and load voltage remains within the 0-600V range. The input voltage tolerance (1.14VDC vs. 1.2VDC main part) is acceptable for standard relay driver circuit designs. Applications must account for the higher on-state resistance (120 ohms vs. 50 ohms), which may increase forward voltage drop across the relay.

Q: Why is AQW224NA rated for only 400V load voltage?

A: AQW224NA is specified with a maximum load voltage of 400V, making it unsuitable for applications requiring the full 600V load voltage range of the PS7160L-2A-A. Selection of this substitute requires design confirmation that application load voltages do not exceed 400V.

Q: Are all substitutes compatible with surface mount assembly processes?

A: All substitute parts feature identical 8-SMD (0.300", 7.62mm) package geometry and Gull Wing termination style. No modifications to PCB land patterns or assembly parameters are required for mechanical substitution.

Q: What is the difference in on-state resistance between the main part and substitutes?

A: PS7160L-2A-A and PAA193STR both specify 50 ohms maximum on-state resistance. AQW216A specifies 120 ohms maximum, and AQW224NA specifies 100 ohms maximum. Lower on-state resistance reduces forward voltage drop and heat dissipation during relay conduction. Applications with strict voltage drop or thermal requirements should prioritize PAA193STR or PS7160L-2A-A specifications.

Q: What is the compliance difference between the main part and substitutes?

A: PS7160L-2A-A carries REACH Affected status and unspecified RoHS compliance. All three substitute parts are ROHS3 Compliant and REACH Unaffected, providing improved environmental and regulatory compliance alignment with current manufacturing and supply chain standards.

Q: Does package format differ between the main part and substitutes?

A: All four parts utilize identical 8-SMD (0.300", 7.62mm) package and Gull Wing termination. PAA193STR is supplied in Tape & Reel format, while AQW216A and AQW224NA are supplied in Tube packaging. These packaging differences affect component handling and assembly logistics only; electrical and mechanical compatibility remains unchanged.
