G3MC-201P DC24 Equivalent & Substitute Parts

Part Overview

The G3MC-201P DC24 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 operates with a DC24V input and controls AC loads up to 1A at 75-264V with zero-cross switching. The product is currently obsolete, necessitating identification of functionally equivalent alternatives that maintain compatibility with existing circuit designs while meeting current availability and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the G3MC-201P DC24 are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Circuit configuration: SPST-NO (1 Form A)
• Package type: 4-SIP
• Mounting type: Through Hole
• Termination style: PC Pin
• Load voltage range: 75 V ~ 264 V
• Output type: AC with zero-cross switching capability

Secondary Compatibility Criteria:

• Input voltage range: 19.2 ~ 28.8VDC (or compatible range)
• Load current rating: 1 A (or higher)
• RoHS compliance status

Substitute parts are grouped into two categories: manufacturer-recommended alternatives and similar cross-compatible devices from alternative manufacturers. All listed substitutes maintain the core electrical and mechanical specifications required for direct replacement in applications designed for the G3MC-201P DC24.

Parameter Comparison

Engineering Selection Recommendations

G3CN-202P1-US DC3-28 (Omron - Manufacturer Recommended)

This substitute is the manufacturer-recommended alternative from Omron Automation and Safety. It maintains active product status and full RoHS compliance. The primary distinction is an increased load current rating of 2A compared to the original 1A specification, providing additional design margin. The input voltage range expands to 3-28VDC, offering broader operational flexibility. All other electrical and mechanical parameters remain equivalent to the G3MC-201P DC24.

AQG12124 (Panasonic Electric Works)

This Panasonic alternative provides direct electrical and mechanical equivalence to the original G3MC-201P DC24. Input voltage range, load current, and output characteristics match the original specification exactly. The device maintains active product status and ROHS3 compliance. Selection of this substitute is appropriate when Panasonic component qualification is acceptable within the design environment.

AQG12224 (Panasonic Electric Works)

This Panasonic alternative matches the G3MC-201P DC24 across all critical parameters with the exception of output type specification, which is listed as AC without explicit zero-cross designation. Input voltage, load current, load voltage range, package, and mounting specifications are identical. The device maintains active product status and ROHS3 compliance. This substitute is suitable for applications where zero-cross switching is not a functional requirement.

Frequently Asked Questions (FAQ)

Q: Can the G3CN-202P1-US DC3-28 be used as a direct replacement for the G3MC-201P DC24?

A: Yes. The G3CN-202P1-US DC3-28 is the manufacturer-recommended substitute. It maintains identical circuit configuration, package type, mounting method, and load voltage specifications. The increased load current rating (2A vs. 1A) and expanded input voltage range (3-28VDC vs. 19.2-28.8VDC) provide enhanced capability without compromising compatibility.

Q: What is the difference between the Panasonic AQG12124 and AQG12224?

A: Both devices are mechanically and electrically equivalent to the G3MC-201P DC24 in terms of input voltage, load current, and load voltage specifications. The primary difference is the output type designation: AQG12124 specifies AC with zero-cross switching, while AQG12224 specifies AC output without explicit zero-cross notation. Selection depends on whether zero-cross switching functionality is required by the application.

Q: Are all substitute parts available in the same 4-SIP package?

A: Yes. All listed substitute parts utilize the 4-SIP package with through-hole PC pin termination, ensuring mechanical compatibility with existing PCB layouts designed for the G3MC-201P DC24.

Q: Do all substitutes meet RoHS compliance requirements?

A: Yes. The G3CN-202P1-US DC3-28 is RoHS Compliant. The Panasonic alternatives AQG12124 and AQG12224 are ROHS3 Compliant. All substitutes satisfy RoHS regulatory requirements.

Q: What is the input voltage compatibility range for each substitute?

A: The G3MC-201P DC24 operates at 19.2-28.8VDC. The G3CN-202P1-US DC3-28 accepts a broader range of 3-28VDC. The Panasonic alternatives AQG12124 and AQG12224 match the original specification at 19.2-28.8VDC. All substitutes are compatible with standard DC24V control circuits.

Q: Can substitutes with higher load current ratings be used in applications designed for 1A?

A: Yes. The G3CN-202P1-US DC3-28 is rated for 2A load current. Using a higher-rated device in a 1A application introduces no functional incompatibility and provides additional design margin.
