PS7141EL-1A-A Solid State Relay - Equivalent & Substitute Parts

Part Overview

The PS7141EL-1A-A is a Surface Mount Solid State Relay (SSR) with SPST-NO (1 Form A) configuration, rated for 120mA load current at 0-400V output voltage range with 1.2VDC input. Manufactured by CEL as part of the PS/OCMOS series, this component is classified as Obsolete product status. Due to its discontinued status, identifying equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for new designs and replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PS7141EL-1A-A are selected based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

• Circuit Configuration: SPST-NO (1 Form A) topology
• Load Voltage Range: 0 V ~ 400 V
• Package/Case: 6-SMD (0.300", 7.62mm)
• Termination Style: Gull Wing
• Output Type: AC, DC capability
• Mounting Type: Surface Mount

All substitute parts maintain the same package footprint and electrical switching capability. Load current variations are acceptable within component specifications, as are input voltage and on-state resistance differences, provided they remain within acceptable operating ranges for the target application.

Engineering Selection Recommendations

PVT412LSPBF (Infineon Technologies) - This substitute maintains identical input voltage (1.2VDC) and load current (120mA) specifications to the original PS7141EL-1A-A. The device features improved on-state resistance (35 Ohms vs 50 Ohms) and carries ROHS3 compliance with Active product status, ensuring long-term availability and supply chain continuity.

AQV214EA (Panasonic Electric Works) - This substitute matches the load current (120mA) and on-state resistance (50 Ohms) of the original component. Input voltage is 1.14VDC, closely aligned to the original 1.2VDC specification. The device holds Active product status, ROHS3 compliance, and REACH Unaffected designation, providing design flexibility for new applications.

AQV204AZ (Panasonic Electric Works) - This substitute offers higher load current capability (150mA vs 120mA) and significantly reduced on-state resistance (16 Ohms). Input voltage requirement is 2.3VDC. While suitable for applications requiring improved performance margins, this part should be selected when the higher input voltage requirement is compatible with the system design.

All substitute parts share identical package geometry (6-SMD with Gull Wing termination), enabling direct mechanical replacement on PCBs designed for the PS7141EL-1A-A footprint.

Frequently Asked Questions (FAQ)

Q: Can PVT412LSPBF directly replace PS7141EL-1A-A in existing designs? A: Yes. PVT412LSPBF maintains identical electrical parameters (1.2VDC input, 120mA load current) and physical package geometry, enabling direct substitution without design modifications.

Q: What is the primary difference between AQV204AZ and AQV214EA? A: AQV204AZ is rated for 150mA load current with 16 Ohms on-state resistance and requires 2.3VDC input. AQV214EA is rated for 120mA load current with 50 Ohms on-state resistance and requires 1.14VDC input. Selection depends on the control circuit voltage levels and load current requirements of the application.

Q: Are all substitute parts in Active product status? A: Yes. PVT412LSPBF, AQV204AZ, and AQV214EA are all classified as Active products, ensuring continued manufacturing and supplier availability, unlike the Obsolete PS7141EL-1A-A.

Q: Do substitute parts use the same packaging format? A: Yes. All substitute parts use 6-SMD (0.300", 7.62mm) packages with Gull Wing termination, maintaining compatibility with existing printed circuit board layouts designed for the PS7141EL-1A-A.

Q: Which substitute offers the lowest on-state resistance? A: AQV204AZ provides the lowest on-state resistance at 16 Ohms maximum, compared to 50 Ohms for the original PS7141EL-1A-A and 35 Ohms for PVT412LSPBF.

Q: What compliance certifications do the substitute parts carry? A: PVT412LSPBF and AQV214EA both carry ROHS3 compliance. AQV214EA is additionally REACH Unaffected, while PVT412LSPBF is REACH Unaffected. AQV204AZ is RoHS Compliant with REACH Unaffected status.
