CPC1962G Solid State Relay - Equivalent & Substitute Parts

Part Overview

The CPC1962G is a solid state relay (SSR) manufactured by IXYS Integrated Circuits Division, configured as a SPST-NO (Single Pole Single Throw - Normally Open) switching device. This component is designed for AC load switching applications with zero-cross detection capability. The CPC1962G is classified as obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CPC1962G is determined by strict adherence to the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Circuit configuration must remain SPST-NO (1 Form A)
• Output type must be AC with zero-cross detection
• Input voltage must be compatible at 1.2 VDC
• Package and mounting type must be 6-DIP (0.300", 7.62mm) through-hole with PC pin termination
• Load voltage rating must equal or exceed the original specification (0 V ~ 600 V minimum)
• Load current rating must equal or exceed the original specification (300 mA minimum)

The CPC1972G qualifies as a direct substitute based on these parameters. Both components share identical circuit topology, input voltage requirements, package configuration, and mounting characteristics. The CPC1972G provides enhanced electrical performance with increased load voltage capability (0 V ~ 800 V) and maintains the same input control voltage specification.

Parameter Comparison

Engineering Selection Recommendations

The CPC1972G is the manufacturer-recommended substitute for the obsolete CPC1962G. Both components are manufactured by IXYS Integrated Circuits Division and maintain identical circuit topology and package specifications, ensuring direct PCB compatibility without layout modifications.

The CPC1972G offers the advantage of active product status, ensuring continued availability and supply chain reliability. The substitute component achieves ROHS3 compliance, meeting current environmental and regulatory requirements for new designs and system upgrades.

Load current specification differs between the two components: the CPC1962G is rated for 300 mA while the CPC1972G is rated for 250 mA. Applications requiring the full 300 mA load current capacity must evaluate whether the reduced rating of the substitute component is acceptable for the specific switching application. Load voltage capability is enhanced in the substitute component (800 V versus 600 V), providing additional margin for applications operating at higher voltage levels.

Frequently Asked Questions (FAQ)

Q: Can the CPC1972G be used as a direct replacement for the CPC1962G in existing designs?

A: Yes, the CPC1972G provides direct PCB compatibility due to identical 6-DIP package configuration and PC pin termination. No layout modifications are required. However, the reduced load current rating (250 mA versus 300 mA) must be evaluated against application requirements.

Q: What is the primary difference between these two components?

A: The CPC1972G provides enhanced load voltage capability (800 V versus 600 V) and is an active product with ROHS3 compliance. The CPC1962G offers higher load current capacity (300 mA versus 250 mA). Component selection depends on whether load voltage or load current capacity is the limiting factor in the application.

Q: Are there any package or mounting differences between the CPC1962G and CPC1972G?

A: No. Both components use identical 6-DIP (0.300", 7.62mm) packaging with through-hole mounting and PC pin termination. They are mechanically and electrically interchangeable from a package perspective.

Q: What is the significance of the CPC1962G being obsolete?

A: Obsolete status indicates the component is no longer manufactured or supported by IXYS Integrated Circuits Division. The CPC1972G, classified as active, ensures continued availability, technical support, and supply chain access for new applications and system maintenance.

Q: Does the CPC1972G meet current environmental compliance standards?

A: Yes, the CPC1972G is ROHS3 compliant, meeting current environmental and regulatory requirements. The CPC1962G compliance status is not specified in available documentation.

Q: Are the input voltage requirements identical between these components?

A: Yes. Both the CPC1962G and CPC1972G require 1.2 VDC input voltage for control signal activation. Control circuit design remains unchanged when substituting between these components.
