PS7142L-1B-A

Part Overview

The PS7142L-1B-A is a Solid State Relay (SSR) SPST-NC configuration manufactured by CEL, designed for switching applications with AC and DC loads up to 400V at 200mA. The product status is obsolete, making it necessary to identify qualified substitute components that maintain equivalent electrical and mechanical performance for continued system support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution criteria for SSR SPST-NC relays are based on functional equivalence within the specified electrical and mechanical parameters. The AQV454A qualifies as a substitute based on the following critical parameters:

• Circuit Configuration: Both parts feature identical SPST-NC (1 Form B) switching configuration
• Output Voltage Range: Both support 0 V ~ 400 V load voltage
• Mounting and Package: Both use surface mount in 6-SMD (0.300", 7.62mm) with Gull Wing termination
• Input Control Voltage: Both operate with comparable DC input voltages (1.2VDC vs 1.14VDC)
• Load Current Rating: AQV454A rated at 150mA is within acceptable range for systems designed for up to 200mA

Parameter Comparison

Engineering Selection Recommendations

Recommendation: AQV454A for ongoing procurement

The AQV454A (Panasonic Electric Works PhotoMOS™ series) serves as the qualified substitute for the obsolete PS7142L-1B-A. The AQV454A is actively manufactured and maintains identical circuit configuration, package geometry, and load voltage specifications. The product is RoHS3 Compliant and carries REACH Unaffected status, providing regulatory compliance advantages over the original obsolete part.

Design engineers must note that the AQV454A operates at a lower maximum load current (150mA vs 200mA) and exhibits higher on-state resistance (16 Ohms vs 12 Ohms). These differences require verification that the substitution does not exceed the thermal and current handling capabilities of the target application circuit. Applications operating at or near the original 200mA specification may experience altered circuit performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can AQV454A directly replace PS7142L-1B-A in existing PCBs? A: Yes. Both parts use identical 6-SMD (0.300", 7.62mm) surface mount packages with Gull Wing termination. No PCB rework is required for physical installation.

Q: What are the electrical differences between these parts? A: The AQV454A has a maximum load current rating of 150mA compared to the PS7142L-1B-A at 200mA, and on-state resistance of 16 Ohms versus 12 Ohms. Both support identical 0-400V load voltage ranges and comparable input control voltages (1.14VDC vs 1.2VDC).

Q: Why is the PS7142L-1B-A obsolete? A: The product status is listed as obsolete, indicating it is no longer manufactured by CEL. The AQV454A represents an active, currently available alternative with equivalent functionality.

Q: Are there regulatory compliance differences? A: Yes. The AQV454A is RoHS3 Compliant and REACH Unaffected, while the PS7142L-1B-A is REACH Affected. Both carry EAR99 ECCN classification and the same HTSUS code (8536.41.0030).

Q: Should I test the AQV454A in my application? A: Engineers must evaluate whether the reduced current capacity (150mA) and increased on-state resistance (16 Ohms) are acceptable for the target application circuit. Circuit simulation and performance validation within design constraints is standard engineering practice.

Q: What is the difference between PS7142L-1B-A packaging and AQV454A packaging? A: PS7142L-1B-A is supplied without specified packaging designation. AQV454A is supplied in Tube packaging. Both use identical 6-SMD surface mount components with Gull Wing termination.
