PS7142L-1C-A

Part Overview

The PS7142L-1C-A is a solid-state relay manufactured by CEL, configured as SPST-NO + SPST-NC (1 Form A and B) in an 8-SMD package with 0.300" (7.62mm) pitch. This component is rated for 200 mA load current across 0 V to 400 V AC/DC applications with a maximum on-state resistance of 12 Ohms and 1.2 VDC input voltage. The product status is obsolete, making identification of suitable alternative components necessary for design continuation and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS7142L-1C-A is evaluated based on the following critical electrical and mechanical parameters:

Electrical Parameters: Load voltage range (0 V ~ 400 V), circuit configuration (SPST-NO + SPST-NC), output type (AC, DC), and load current capacity.

Mechanical Parameters: Package type (8-SMD with 0.300" pitch), mounting style (Surface Mount), and termination style (Gull Wing).

Input Parameters: Input voltage requirements must be compatible with system specifications.

The AQW654A from Panasonic Electric Works is a compatible alternative that maintains the same circuit topology, package configuration, and voltage operating range. While the load current rating is lower (120 mA versus 200 mA) and on-state resistance is higher (16 Ohms versus 12 Ohms), it operates within the same 400 V maximum load voltage specification and uses identical packaging, enabling direct board-level substitution where load current does not exceed 120 mA.

Parameter Comparison

Engineering Selection Recommendations

The AQW654A is the primary alternative for PS7142L-1C-A replacement applications. The substitute maintains identical package geometry and circuit topology, enabling PCB-level compatibility without layout modifications. The AQW654A benefits from active product status and RoHS compliance, eliminating obsolescence and regulatory constraints associated with the original PS7142L-1C-A.

Load current derating is the critical selection parameter: the AQW654A supports a maximum of 120 mA continuous load current, compared to 200 mA for the PS7142L-1C-A. Applications requiring sustained currents above 120 mA require design modification or alternative component selection. Input voltage compatibility is maintained, with both devices operating from approximately 1.2 VDC input nominal.

The REACH Unaffected status of the AQW654A simplifies regulatory compliance for new designs and manufacturing operations in jurisdictions where REACH-compliant sourcing is required.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between PS7142L-1C-A and AQW654A? A: Both devices share identical circuit topology (SPST-NO + SPST-NC), package configuration (8-SMD, 0.300" pitch), and maximum load voltage (400 V). The AQW654A supports a maximum load current of 120 mA and on-state resistance of 16 Ohms, compared to 200 mA and 12 Ohms for the PS7142L-1C-A. The AQW654A is an active product with RoHS compliance.

Q: Is AQW654A a direct pin-for-pin replacement? A: Yes. Both devices utilize the same 8-SMD package with gull wing termination and 0.300" (7.62mm) pitch, enabling direct PCB substitution without layout or routing modifications.

Q: Can I use AQW654A in applications requiring 200 mA load current? A: No. The AQW654A is rated for a maximum of 120 mA continuous load current. Applications requiring 200 mA operation require either the original PS7142L-1C-A (if available from inventory) or an alternative component rated for the required current.

Q: What are the compliance differences between these parts? A: The AQW654A is RoHS Compliant and REACH Unaffected. The PS7142L-1C-A is REACH Affected and RoHS status is not specified. For new designs subject to RoHS or REACH regulations, the AQW654A is the appropriate selection.

Q: Are input voltage specifications compatible? A: Yes. Both devices operate from approximately 1.2 VDC input. The AQW654A at 1.14 VDC and PS7142L-1C-A at 1.2 VDC are functionally equivalent for standard control logic interface applications.

Q: What is the inventory status of AQW654A? A: Panasonic Electric Works AQW654A devices are currently in active production with 1815 units available in new original stock condition.
