CPC1964Y Equivalent & Substitute Parts

Part Overview

The CPC1964Y 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 operates with 1.2VDC input and features zero-cross AC output switching. The CPC1964Y is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CPC1964Y is determined by the following critical parameters:

• Circuit Configuration: Must remain SPST-NO (1 Form A) to maintain identical switching topology
• Input Voltage: Must match 1.2VDC specification for control signal compatibility
• Load Current Rating: Must support minimum 1A continuous current
• Output Voltage Range: Substitute must accommodate the required load voltage range
• Mounting Type: Through-hole mounting required for PCB compatibility
• Termination Style: PC pin termination required for board-level integration
• Output Type: AC with zero-cross switching capability required for application performance

The CPC1965Y qualifies as a manufacturer-recommended substitute. While it operates within a reduced load voltage range (0–600V versus 0–800V), it maintains all critical functional parameters: identical circuit configuration, input voltage, load current rating, mounting type, and termination style. The CPC1965Y is classified as active product status, ensuring ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

The CPC1965Y is the manufacturer-recommended substitute for the obsolete CPC1964Y. Both components share identical control and switching characteristics: SPST-NO configuration, 1.2VDC input, 1A load current, and AC zero-cross output switching.

The primary design consideration is load voltage range. The CPC1964Y supports 0–800V, while the CPC1965Y supports 0–600V. Selection of the CPC1965Y is appropriate for applications where the maximum load voltage does not exceed 600V.

The CPC1965Y carries active product status, ensuring manufacturer support and component availability. It meets ROHS3 compliance requirements, supporting modern procurement and environmental standards. Both components maintain identical moisture sensitivity classification and termination specifications, enabling direct board-level substitution within the voltage constraint.

Frequently Asked Questions (FAQ)

Q: Can the CPC1965Y replace the CPC1964Y in all applications?

A: The CPC1965Y is a functional substitute provided the maximum load voltage in your application does not exceed 600V. If your circuit requires operation above 600V, the CPC1965Y is not suitable. All other electrical and mechanical parameters are compatible.

Q: What is the difference in package configuration between these parts?

A: The CPC1964Y uses a 4-SIP package, while the CPC1965Y uses an 8-SIP package with 4 leads. Both are through-hole mounted with PC pin termination. PCB layout modifications may be required to accommodate the different package footprint.

Q: Why is the CPC1964Y obsolete?

A: The CPC1964Y has been discontinued by the manufacturer. The CPC1965Y represents the active product line continuation within the CPC series and is recommended for new designs and ongoing procurement.

Q: Are there compliance differences between these parts?

A: The CPC1965Y is ROHS3 compliant. Both components are REACH unaffected and carry identical moisture sensitivity classification (MSL 1 - Unlimited).

Q: What is zero-cross switching and why is it important?

A: Zero-cross switching ensures the SSR activates or deactivates only when the AC voltage crosses zero, minimizing electromagnetic interference and switching stress. Both the CPC1964Y and CPC1965Y feature this capability.

Q: Can I use the CPC1965Y if my application requires 800V operation?

A: No. The CPC1965Y maximum load voltage is 600V. For applications requiring 800V operation, alternative components rated for that voltage range must be identified.
