G3MC-201P DC12 Equivalent & Substitute Parts

Part Overview

The G3MC-201P DC12 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 9.6–14.4 VDC input and controls AC loads from 75–264 V at 1 A maximum current, utilizing zero-cross switching technology. The product is classified as obsolete, necessitating identification of functionally equivalent alternatives for new designs and ongoing maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the G3MC-201P DC12 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A)
• Package / Case: Must be 4-SIP
• Mounting Type: Must be Through Hole
• Termination Style: Must be PC Pin
• Output Type: Must be AC with Zero Cross switching
• Load Voltage Range: Must accommodate 75–264 V
• Load Current: Must support minimum 1 A
• Input Voltage Range: Must be compatible with or encompass 9.6–14.4 VDC

Two substitute parts meet these criteria with varying degrees of parameter alignment:

1. G3CN-202P1-US DC3-28 (Omron Automation and Safety): Meets all structural and functional requirements; input voltage range is broader (3–28 VDC); load current is higher (2 A).

2. AQG12112 (Panasonic Electric Works): Meets all structural and functional requirements; input voltage range is identical (9.6–14.4 VDC); load current is identical (1 A); manufacturer differs.

Parameter Comparison

Engineering Selection Recommendations

G3CN-202P1-US DC3-28 is the manufacturer-recommended substitute. As an active product from the original manufacturer (Omron Automation and Safety), it provides continuity of supply and design support. The broader input voltage range (3–28 VDC) and higher load current rating (2 A) provide operational margin beyond the original specification. This part is suitable for direct replacement in applications where the original G3MC-201P DC12 was specified.

AQG12112 is a functionally equivalent alternative from Panasonic Electric Works. It maintains identical input voltage (9.6–14.4 VDC) and load current (1 A) specifications as the original part, with matching package and termination characteristics. This part is suitable for applications requiring exact parameter matching and is available in higher inventory quantities. RoHS compliance is confirmed.

Both substitutes are active products with confirmed availability, eliminating supply chain risk associated with the obsolete G3MC-201P DC12.

Frequently Asked Questions (FAQ)

Q: Can the G3CN-202P1-US DC3-28 be used as a direct replacement for the G3MC-201P DC12?

A: Yes. Both parts share identical circuit configuration (SPST-NO), output type (AC, Zero Cross), load voltage range (75–264 V), package (4-SIP), mounting type (Through Hole), and termination style (PC Pin). The G3CN-202P1-US DC3-28 has a broader input voltage range and higher load current rating, making it compatible with applications designed for the G3MC-201P DC12.

Q: What is the difference between the G3CN-202P1-US DC3-28 and AQG12112?

A: Both are functionally equivalent substitutes with identical circuit configuration, output type, load voltage range, package, mounting type, and termination style. The primary differences are manufacturer (Omron vs. Panasonic), input voltage range (3–28 VDC vs. 9.6–14.4 VDC), and load current (2 A vs. 1 A). The G3CN-202P1-US DC3-28 offers greater operational flexibility; the AQG12112 matches the original specifications exactly.

Q: Are both substitute parts RoHS compliant?

A: The AQG12112 is confirmed RoHS compliant. RoHS compliance status for the G3CN-202P1-US DC3-28 is not specified in the provided data.

Q: Can I use the AQG12112 if my circuit requires a 12 VDC input?

A: Yes. The AQG12112 input voltage range (9.6–14.4 VDC) encompasses 12 VDC operation, matching the original G3MC-201P DC12 specification.

Q: What is the significance of the 4-SIP package for these parts?

A: The 4-SIP (Single In-line Package) is a through-hole package with four pins, designed for direct insertion into PCB holes. All three parts (original and substitutes) use this identical package, ensuring mechanical and electrical compatibility on existing PCBs without layout modifications.
