CPC1964G Solid State Relay - Equivalent & Substitute Parts

Part Overview

The CPC1964G is a solid state relay (SSR) manufactured by IXYS Integrated Circuits Division, configured as a SPST-NO (Single Pole Single Throw - Normally Open) relay with 1A load capacity and 0-800V output voltage range. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The through-hole 16-DIP package format and PC pin termination style are standard for this relay category.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CPC1964G is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: Must remain SPST-NO (1 Form A) to maintain identical switching topology
• Package / Case: Must be 16-DIP (0.300", 7.62mm), 4 Leads for PCB compatibility
• Mounting Type: Must be Through Hole to match existing board layouts
• Termination Style: Must be PC Pin for direct connection compatibility
• Input Voltage: Must be 1.2VDC to ensure control signal compatibility
• Output Type: Must be AC, Zero Cross to maintain load switching characteristics
• Load Current: Must be rated for minimum 1 A operation

The CPC1965G meets all these criteria while offering an active product status and improved availability. The primary difference is the maximum load voltage specification, which is reduced from 800V to 600V in the substitute part.

Parameter Comparison

Engineering Selection Recommendations

The CPC1965G is the designated manufacturer substitute for the obsolete CPC1964G. Both components share identical electrical characteristics for input control signals, circuit topology, and load current capacity. The CPC1965G maintains active product status with ROHS3 compliance certification, ensuring long-term availability and regulatory alignment for new designs and production runs.

Selection of the CPC1965G is appropriate for applications where the maximum load voltage requirement does not exceed 600V. For applications requiring the full 800V load voltage range of the original CPC1964G, alternative solid state relay solutions from the CPC series or other manufacturers must be evaluated.

Frequently Asked Questions (FAQ)

Q: Can the CPC1965G be used as a direct replacement for the CPC1964G in existing designs?

A: The CPC1965G is a direct pin-for-pin and functional replacement provided that the application load voltage does not exceed 600V. Both components use identical 16-DIP packaging, PC pin termination, and control signal specifications.

Q: What is the primary difference between CPC1964G and CPC1965G?

A: The maximum load voltage specification differs: CPC1964G supports 0-800V while CPC1965G supports 0-600V. All other electrical and mechanical parameters remain equivalent.

Q: Does the CPC1965G require any PCB layout modifications?

A: No. The CPC1965G maintains the same 16-DIP (0.300", 7.62mm) package footprint and PC pin termination as the CPC1964G, allowing direct board-level substitution without layout changes.

Q: What is the significance of the active product status for CPC1965G?

A: Active product status indicates current manufacturing and distribution availability. This ensures reliable component sourcing for both immediate replacement needs and future production requirements, unlike the obsolete CPC1964G.

Q: Are there compliance differences between the two parts?

A: The CPC1965G carries ROHS3 compliance certification. Both components maintain REACH Unaffected status and identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited).
