PS7141CL-2A-A Solid State Relay SPST-NO Equivalent & Substitute Parts

Part Overview

The PS7141CL-2A-A is a Solid State Relay (SSR) manufactured by CEL, configured as a SPST-NO (Single Pole Single Throw - Normally Open) relay with dual Form A circuits. This component is rated for 120 mA load current across a 0-400V operating range and features surface mount gull wing termination in an 8-SMD package. The PS7141CL-2A-A is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PS7141CL-2A-A is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Circuit Configuration: SPST-NO (1 Form A) x 2
• Output Type: AC, DC
• Load Current: 120 mA
• Package / Case: 8-SMD (0.300", 7.62mm)
• Termination Style: Gull Wing
• Mounting Type: Surface Mount

Allowable Parameter Variations:

• Voltage - Input: Within ±0.06 VDC tolerance
• Voltage - Load Range: Equal to or greater than 0-400V
• On-State Resistance (Max): Equal to or less than 35 Ohms

The substitute parts identified below satisfy all mandatory matching parameters and operate within allowable electrical tolerances for direct functional replacement.

Engineering Selection Recommendations

PVT422SPBF (Infineon Technologies) - Primary Substitute

The PVT422SPBF is the optimal substitute for the PS7141CL-2A-A. This part maintains identical electrical specifications: 1.2 VDC input voltage, 0-400V load voltage range, 120 mA load current, and 35 Ohms maximum on-state resistance. The PVT422SPBF is in active production status with ROHS3 compliance and carries REACH Unaffected designation. The package, termination style, and circuit configuration are identical. Inventory availability is substantial at 16,100 pieces.

AQW210HLA (Panasonic Electric Works) - Secondary Substitute

The AQW210HLA is a functional substitute with the following considerations: Input voltage is 1.14 VDC (within tolerance), load voltage range is 0-350V (50V lower than the original), and on-state resistance is 25 Ohms (superior to the original 35 Ohms maximum). The AQW210HLA is in active production with RoHS Compliant status. The reduced load voltage range (350V vs. 400V) restricts this part to applications where maximum load voltage does not exceed 350V. Inventory availability is 2,340 pieces.

Frequently Asked Questions (FAQ)

Q: Can the AQW210HLA be used in all applications where the PS7141CL-2A-A was specified?

A: No. The AQW210HLA has a maximum load voltage rating of 350V, compared to the PS7141CL-2A-A specification of 0-400V. The AQW210HLA is suitable only for applications where the load voltage does not exceed 350V.

Q: Are the PVT422SPBF and PS7141CL-2A-A pin-compatible?

A: Yes. Both parts use identical 8-SMD (0.300", 7.62mm) packages with gull wing termination. PCB footprints are directly compatible.

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

A: The PS7141CL-2A-A and PVT422SPBF both specify 35 Ohms maximum on-state resistance. The AQW210HLA specifies 25 Ohms maximum, which is lower and represents improved performance in this parameter.

Q: Does the Moisture Sensitivity Level (MSL) difference affect component selection?

A: The PS7141CL-2A-A has MSL 1 (Unlimited), the AQW210HLA has Not Applicable, and the PVT422SPBF has MSL 4 (72 Hours). MSL ratings affect storage and handling requirements. The PVT422SPBF requires controlled humidity storage for 72 hours prior to reflow soldering.

Q: Are both substitute parts RoHS compliant?

A: Yes. The AQW210HLA is RoHS Compliant, and the PVT422SPBF is ROHS3 Compliant. Both meet current environmental compliance requirements.

Q: What is the input voltage tolerance between parts?

A: The PS7141CL-2A-A specifies 1.2 VDC input, the AQW210HLA specifies 1.14 VDC, and the PVT422SPBF specifies 1.2 VDC. The 0.06 VDC difference in the AQW210HLA is within acceptable tolerance for SSR input specifications.
