G3MC-202P DC5 Equivalent & Substitute Parts

Part Overview

The G3MC-202P DC5 is a solid-state relay (SSR) manufactured by Omron Automation and Safety, configured as a SPST-NO (1 Form A) device in a 4-SIP package. This component is designed for AC load switching applications with zero-cross detection, rated for 2A load current at 75V to 264V output voltage, with a 4-6VDC input control signal. The product is currently classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the G3MC-202P DC5 is determined by the following critical parameters that must remain consistent or compatible:

• Circuit Configuration: SPST-NO (1 Form A) topology must be maintained
• Output Specifications: AC load switching with zero-cross detection capability
• Load Rating: 2A continuous current at 75V to 264V output voltage range
• Package Form Factor: 4-SIP through-hole configuration with PC pin termination
• Input Control Signal: DC voltage control (original: 4-6VDC; substitute may have extended range)
• Compliance: RoHS compliance status

The G3CN-202P1-US DC3-28 qualifies as a direct substitute because it maintains identical circuit topology, load specifications, package configuration, and termination style. The primary difference is an extended input voltage range (3-28VDC versus 4-6VDC), which provides greater design flexibility while remaining backward compatible with the original 4-6VDC control signal requirement.

Parameter Comparison

Engineering Selection Recommendations

The G3CN-202P1-US DC3-28 is the manufacturer-recommended substitute for the obsolete G3MC-202P DC5. Both components maintain RoHS compliance and are manufactured by Omron Automation and Safety, ensuring consistent quality and reliability standards.

The G3CN series represents the active product line continuation, with the G3CN-202P1-US DC3-28 offering extended input voltage range capability (3-28VDC) while preserving all critical load-switching specifications. This extended input range provides design flexibility for applications requiring variable control voltages, while remaining fully compatible with systems originally designed for the 4-6VDC input specification.

For applications currently using the G3MC-202P DC5, direct substitution with the G3CN-202P1-US DC3-28 requires no circuit modifications, as the identical package footprint, pin configuration, and electrical load characteristics ensure drop-in compatibility.

Frequently Asked Questions (FAQ)

Q: Can the G3CN-202P1-US DC3-28 directly replace the G3MC-202P DC5 without circuit modifications?

A: Yes. Both components share identical circuit topology (SPST-NO), load specifications (2A at 75-264V AC), package configuration (4-SIP through-hole), and pin termination style (PC pin). The extended input voltage range of the substitute (3-28VDC) is backward compatible with the original 4-6VDC control signal requirement.

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

A: The G3CN-202P1-US DC3-28 features an extended input voltage operating range (3-28VDC) compared to the G3MC-202P DC5 (4-6VDC). All load-switching specifications, package form factor, and output characteristics remain identical.

Q: Why is the G3MC-202P DC5 classified as obsolete?

A: The G3MC series has been superseded by the G3CN series in Omron's product portfolio. The G3CN-202P1-US DC3-28 represents the active continuation of this product line with enhanced input voltage flexibility.

Q: Are there any compliance or certification differences between these parts?

A: Both components are RoHS compliant. The G3CN-202P1-US DC3-28 carries ECCN EAR99 classification and HTSUS code 8536.49.0055, while the G3MC-202P DC5 carries ECCN EAR99 and HTSUS code 8536.41.0030. Both meet equivalent regulatory standards for industrial solid-state relay applications.

Q: What packaging options are available for the substitute part?

A: The G3CN-202P1-US DC3-28 is supplied in bulk packaging, whereas the original G3MC-202P DC5 was supplied with standard packaging designation. Both maintain the identical 4-SIP component form factor for through-hole PCB mounting.
