CPC1317PTR Equivalent & Substitute Parts

Part Overview

The CPC1317PTR is a solid-state relay (SSR) manufactured by IXYS Integrated Circuits Division, part of the OptoMOS® series. This SPST-NO (1 Form A) device is designed for switching applications with a maximum load current of 150 mA across a 0–70 V range. The component features surface mount packaging in an 8-SMD (0.300", 7.62mm) format with gull wing termination.

The CPC1317PTR is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CPC1317PTR is determined by the following critical parameters:

• Circuit Configuration: Must maintain SPST-NO (1 Form A) topology for direct functional replacement
• Input Voltage: Must accept 1.2 VDC control signal
• Load Voltage Range: Must support at least the 0–70 V operating range
• Load Current Capability: Must handle or exceed 150 mA switching capacity
• Output Type: Must support both AC and DC switching
• Package Compatibility: Must use identical 8-SMD (0.300", 7.62mm) surface mount format with gull wing termination
• Compliance: Must maintain ROHS3 compliance and EAR99 classification

The LAA108PTR meets these substitution criteria while offering enhanced electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The LAA108PTR is the manufacturer-recommended substitute for the obsolete CPC1317PTR. Both components maintain ROHS3 compliance and EAR99 classification, ensuring regulatory consistency.

The LAA108PTR offers the following advantages:

• Active Product Status: Ensures long-term availability and supply chain continuity
• Enhanced Electrical Performance: Higher load voltage range (100 V vs. 70 V), increased load current capacity (300 mA vs. 150 mA), and reduced on-state resistance (8 Ohms vs. 16 Ohms)
• Improved Moisture Handling: MSL rating of 1 (Unlimited) compared to MSL 3 (168 Hours), reducing storage and handling constraints
• Identical Package Footprint: Direct PCB layout compatibility with no redesign required
• Same Control Voltage: 1.2 VDC input specification ensures circuit-level compatibility

The LAA108PTR contains two integrated SPST-NO switches within the same package footprint. Applications requiring only a single switch can utilize one channel while leaving the second channel unused, or both channels can be employed for dual-switch applications.

Frequently Asked Questions (FAQ)

Q: Can the LAA108PTR be used as a direct drop-in replacement for the CPC1317PTR?

A: Yes. Both components share identical package dimensions (8-SMD, 0.300", 7.62mm), termination style (gull wing), input voltage (1.2 VDC), output type (AC/DC), and mounting method (surface mount). No PCB modifications are required.

Q: What is the difference between the CPC1317PTR and LAA108PTR circuit configurations?

A: The CPC1317PTR contains one SPST-NO switch, while the LAA108PTR contains two SPST-NO switches integrated into the same package. For single-switch applications, one channel of the LAA108PTR is utilized; the second channel remains available for additional switching functions or is left unused.

Q: Does the LAA108PTR meet the same compliance requirements as the CPC1317PTR?

A: Yes. Both components are ROHS3 compliant and classified as EAR99 for export control purposes. Regulatory and environmental compliance is maintained.

Q: Why does the LAA108PTR have a lower on-state resistance?

A: The LAA108PTR exhibits superior electrical performance characteristics, including reduced on-state resistance (8 Ohms vs. 16 Ohms). This results in lower power dissipation and improved switching efficiency, providing a performance advantage over the obsolete CPC1317PTR.

Q: Is the LAA108PTR suitable for applications requiring 0–70 V load switching?

A: Yes. The LAA108PTR supports a load voltage range of 0–100 V, which exceeds the 0–70 V requirement of the original CPC1317PTR application. Full compatibility is maintained.

Q: What is the significance of the MSL rating difference?

A: The CPC1317PTR has an MSL rating of 3 (168 hours), requiring controlled storage and handling conditions. The LAA108PTR has an MSL rating of 1 (Unlimited), eliminating moisture sensitivity constraints and simplifying inventory management and logistics.

Q: Are there any circuit design modifications required when substituting the LAA108PTR for the CPC1317PTR?

A: No circuit modifications are required. The LAA108PTR maintains identical input voltage, output type, and switching characteristics. The component can be substituted without altering control logic or load circuit design.
