PD2601 Equivalent & Substitute Parts

Part Overview

The PD2601 is a solid-state relay (SSR) manufactured by IXYS Integrated Circuits Division, configured as a SPST-NO (Single Pole Single Throw - Normally Open) device with 1A load capacity. This component operates with a 1.2VDC input and supports AC loads up to 600V with zero-cross switching capability. The device is housed in a 16-DIP package with through-hole PC pin termination and maintains Active product status with full ROHS3 compliance. Equivalent parts are identified when alternative SSR devices share identical mechanical packaging, circuit topology, and core electrical specifications that permit direct functional substitution in applications where the load voltage range permits.

Key Parameters

Substitute Part Grouping Explanation

The DPA4119 qualifies as a manufacturer-recommended substitute for the PD2601 based on the following alignment of critical parameters:

• Circuit Topology: Both devices implement SPST-NO (1 Form A) configuration with identical switching behavior
• Output Switching: Both employ AC output with zero-cross detection
• Load Current Rating: Both are rated for 1A continuous load current
• Package Compatibility: Both utilize 16-DIP (0.300", 7.62mm) with 4 leads and PC pin termination
• Mounting Method: Both are through-hole mounted components
• Compliance: Both maintain ROHS3 compliance and REACH unaffected status

The primary electrical difference lies in the input voltage range (PD2601: 1.2VDC vs. DPA4119: 4.6–10VDC) and load voltage operating window (PD2601: 0–600V vs. DPA4119: 20–140V). Substitution is valid only when the application's load voltage falls within the 20–140V range supported by the DPA4119.

Parameter Comparison

Engineering Selection Recommendations

Selection between the PD2601 and DPA4119 is determined by application load voltage requirements:

• PD2601: Select when load voltage spans 0–600V, particularly for low-voltage AC applications below 20V or high-voltage applications exceeding 140V. Input control voltage of 1.2VDC is required.

• DPA4119: Select when load voltage operates within the 20–140V range and input control voltage is available in the 4.6–10VDC range. This device is the manufacturer-recommended substitute within its specified load voltage window.

Both devices maintain identical product status (Active), ROHS3 compliance, and REACH unaffected designation, ensuring equivalent regulatory and environmental qualification. Mechanical interchangeability is assured through identical 16-DIP packaging and PC pin termination.

Frequently Asked Questions (FAQ)

Q: Can the DPA4119 replace the PD2601 in all applications?

A: No. The DPA4119 is a valid substitute only when the application load voltage operates within 20–140V. Applications requiring load voltages below 20V or above 140V must use the PD2601 or identify alternative devices rated for those voltage ranges.

Q: Are the input voltage requirements different between these devices?

A: Yes. The PD2601 requires 1.2VDC input, while the DPA4119 requires 4.6–10VDC input. The control circuit must supply the appropriate voltage for the selected device.

Q: Is the 16-DIP package identical between both parts?

A: Yes. Both devices use 16-DIP (0.300", 7.62mm) with 4 leads and PC pin termination, ensuring mechanical and electrical pin compatibility on standard through-hole PCB layouts.

Q: Do both devices support zero-cross switching?

A: Yes. Both the PD2601 and DPA4119 incorporate AC output with zero-cross detection, providing synchronized switching at AC line zero-crossing points.

Q: What is the load current rating for both devices?

A: Both devices are rated for 1A continuous load current.

Q: Are there compliance differences between the two parts?

A: No. Both devices are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory standards.
