PS7141L-2A-E3-A Equivalent & Substitute Parts

Part Overview

The PS7141L-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 operates with a 1.2VDC input signal and supports load voltages from 0V to 400V at 150mA maximum load current, suitable for AC and DC switching applications.

The PS7141L-2A-E3-A is classified as obsolete. Equivalent and substitute parts are necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this relay architecture.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS7141L-2A-E3-A is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPST-NO (1 Form A) x 2
• Package type: 8-SMD (0.300", 7.62mm)
• Termination style: Gull Wing
• Load voltage range: 0V ~ 400V
• Output type: AC and DC switching capability
• Mounting type: Surface Mount

Allowable Parameter Variations:

• Input voltage: Substitute parts may operate at different input voltages (1.14VDC or 1.2VDC) provided the control circuit accommodates the specified input requirement
• Load current: Substitute parts rated at or above 150mA are acceptable; lower-rated substitutes are not acceptable
• On-state resistance: Variations are acceptable within the context of application requirements

Two substitute parts meet these criteria and are listed below.

Parameter Comparison

Engineering Selection Recommendations

PAA110PLTR (IXYS Integrated Circuits Division)

The PAA110PLTR is the primary substitute for the PS7141L-2A-E3-A. This part maintains identical input voltage (1.2VDC), load current (150mA), and load voltage range specifications. The PAA110PLTR features superior on-state resistance (25 Ohms maximum versus 30 Ohms), providing improved electrical performance. The part is active in production status with ROHS3 compliance and REACH unaffected certification. Inventory availability is 754 units in Tape & Reel packaging.

AQW214EHAX (Panasonic Electric Works)

The AQW214EHAX is an alternative substitute with full mechanical and electrical compatibility in package, termination, and load voltage specifications. This part operates at a marginally lower input voltage (1.14VDC versus 1.2VDC) and supports a reduced load current rating of 100mA. The AQW214EHAX is suitable for applications where load current does not exceed 100mA. This part is active in production status with ROHS3 compliance and REACH unaffected certification. Inventory availability is 19,099 units in Tape & Reel packaging.

Both substitute parts are active products with superior supply chain availability compared to the obsolete PS7141L-2A-E3-A.

Frequently Asked Questions (FAQ)

Q: Can the AQW214EHAX replace the PS7141L-2A-E3-A in all applications?

A: The AQW214EHAX is mechanically and electrically compatible with the PS7141L-2A-E3-A in package, circuit configuration, and load voltage range. However, the AQW214EHAX is rated for 100mA maximum load current, while the PS7141L-2A-E3-A is rated for 150mA. The AQW214EHAX is suitable only for applications where load current does not exceed 100mA.

Q: What is the difference in on-state resistance between these parts?

A: The PS7141L-2A-E3-A specifies a maximum on-state resistance of 30 Ohms. The PAA110PLTR specifies 25 Ohms maximum, and the AQW214EHAX specifies 35 Ohms maximum. Lower on-state resistance reduces power dissipation and heat generation during relay operation.

Q: Are the input voltage differences significant?

A: The PS7141L-2A-E3-A and PAA110PLTR both require 1.2VDC input. The AQW214EHAX requires 1.14VDC input. These differences are minor and typically accommodated by standard control circuit designs. Verify that the control circuit can supply the specified input voltage for the selected substitute part.

Q: Are all three parts available in the same packaging format?

A: The PS7141L-2A-E3-A is supplied in bulk packaging. Both substitute parts (AQW214EHAX and PAA110PLTR) are supplied in Tape & Reel (TR) format, which is standard for high-volume production environments.

Q: Do the substitute parts have the same moisture sensitivity rating?

A: The PS7141L-2A-E3-A specifies MSL 1 (Unlimited). The PAA110PLTR specifies MSL 3 (168 Hours), requiring controlled storage conditions. The AQW214EHAX specifies MSL Not Applicable. Verify storage and handling requirements for the selected substitute part.

Q: Are all parts ROHS and REACH compliant?

A: The PS7141L-2A-E3-A does not specify ROHS status. Both substitute parts (PAA110PLTR and AQW214EHAX) are ROHS3 compliant. All three parts are REACH unaffected.
