PS7160L-2A-E3-A Equivalent & Substitute Parts

Part Overview

The PS7160L-2A-E3-A is a solid-state relay (SSR) manufactured by CEL, configured as a SPST-NO (Single Pole Single Throw - Normally Open) relay with dual channels in an 8-SMD surface mount package. This component is rated for 90 mA load current at 0–600 V AC/DC output with a 1.2 VDC input control signal and 50 Ohms maximum on-state resistance.

The PS7160L-2A-E3-A is classified as obsolete. Locating equivalent substitute parts is necessary to support ongoing production requirements, maintenance operations, and design continuity for systems currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS7160L-2A-E3-A is determined by strict equivalence across the following critical parameters:

Electrical Compatibility:

• Circuit configuration: SPST-NO (1 Form A) x 2 channels
• Input control voltage: 1.2 VDC
• Load voltage range: 0 V ~ 600 V AC/DC
• On-state resistance: 50 Ohms maximum
• Load current rating: minimum 90 mA (equal or greater)

Mechanical & Package Compatibility:

• Mounting type: Surface Mount
• Package type: 8-SMD (0.300", 7.62mm)
• Termination style: Gull Wing

Regulatory & Environmental:

• Moisture Sensitivity Level: 1 (Unlimited)
• REACH compliance status
• ECCN classification

The PAA193STR from IXYS Integrated Circuits Division meets all substitution criteria. This part maintains identical electrical specifications with the exception of a higher load current rating (100 mA versus 90 mA), which provides additional operational margin. The PAA193STR is pin-compatible, package-compatible, and functionally equivalent for all applications requiring the PS7160L-2A-E3-A.

Parameter Comparison

Engineering Selection Recommendations

The PAA193STR is the direct functional equivalent for the obsolete PS7160L-2A-E3-A. Selection of the PAA193STR is supported by the following factors:

Product Status: The PAA193STR maintains active product status with IXYS Integrated Circuits Division, ensuring ongoing availability and supply chain continuity compared to the obsolete PS7160L-2A-E3-A.

Electrical Equivalence: Both parts share identical input voltage (1.2 VDC), load voltage range (0–600 V), on-state resistance (50 Ohms maximum), and circuit configuration (dual SPST-NO channels). The PAA193STR load current rating of 100 mA exceeds the PS7160L-2A-E3-A requirement of 90 mA, providing operational margin without derating.

Package & Mechanical Compatibility: Both parts utilize the 8-SMD (0.300", 7.62mm) surface mount package with gull wing termination, enabling direct PCB layout compatibility and assembly process alignment.

Regulatory Compliance: The PAA193STR carries ROHS3 compliance certification, exceeding the regulatory posture of the original part. Both parts maintain REACH Unaffected status and EAR99 ECCN classification.

Availability: The PAA193STR is available in Tape & Reel packaging format with substantial inventory levels, supporting both prototype and production-volume requirements.

Frequently Asked Questions (FAQ)

Q: Can the PAA193STR directly replace the PS7160L-2A-E3-A without PCB modifications?

A: Yes. The PAA193STR is pin-compatible and package-compatible with the PS7160L-2A-E3-A. Both parts use the 8-SMD (0.300", 7.62mm) package with gull wing termination. No PCB layout changes are required for substitution.

Q: What is the difference in load current rating between these parts?

A: The PS7160L-2A-E3-A is rated for 90 mA maximum load current. The PAA193STR is rated for 100 mA maximum load current. The higher rating of the PAA193STR provides additional operational margin and does not create compatibility issues in applications designed for the original part.

Q: Are the input control voltage specifications identical?

A: Yes. Both the PS7160L-2A-E3-A and PAA193STR require 1.2 VDC input control voltage. No circuit modifications are necessary for the control signal path.

Q: Do both parts support the same load voltage range?

A: Yes. Both parts are rated for 0 V to 600 V AC/DC load voltage operation. The output switching characteristics are equivalent across this entire range.

Q: What is the on-state resistance specification for both parts?

A: Both the PS7160L-2A-E3-A and PAA193STR specify a maximum on-state resistance of 50 Ohms. This parameter is identical and ensures equivalent power dissipation and thermal performance in the conducting state.

Q: Is the PAA193STR available in the same packaging format as the PS7160L-2A-E3-A?

A: Both parts use 8-SMD (0.300", 7.62mm) surface mount packages with gull wing termination. The PAA193STR is supplied in Tape & Reel format, which is standard for production assembly operations. The PS7160L-2A-E3-A was supplied in bulk packaging.

Q: What is the moisture sensitivity level for the PAA193STR?

A: The PAA193STR carries an MSL rating of 1 (Unlimited), identical to the PS7160L-2A-E3-A. This indicates no moisture sensitivity restrictions for storage or handling.

Q: Does the PAA193STR meet current regulatory compliance standards?

A: Yes. The PAA193STR is ROHS3 compliant and maintains REACH Unaffected status. Both parts carry EAR99 ECCN classification. The PAA193STR meets or exceeds the regulatory requirements of the original PS7160L-2A-E3-A.
