G3MC-101P DC5 Equivalent & Substitute Parts

Part Overview

The G3MC-101P 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 operates with a 4–6VDC input and controls AC loads between 75–132V at 1A maximum current, utilizing zero-cross switching technology. The product is classified as obsolete, necessitating identification of active equivalent components that maintain functional compatibility within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility 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
• Input Voltage Compatibility: Substitute input voltage range must encompass or be compatible with 4–6VDC
• Load Voltage Range: Substitute load voltage range must equal or exceed 75–132V
• Load Current: Substitute load current must be ≥1A
• Output Type: Must support AC switching with zero-cross capability

The G3MC-101P DC5 has two identified substitutes: the Omron G3CN-202P1-US DC3-28 (manufacturer-recommended) and the Panasonic Electric Works AQG12105 and AQG12205 (similar alternatives). All three maintain the required circuit topology, package format, and through-hole mounting configuration.

Parameter Comparison

Engineering Selection Recommendations

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

This part is the primary recommended substitute. It maintains the same manufacturer lineage and package format while offering expanded electrical specifications: input voltage range of 3–28VDC (encompassing the original 4–6VDC requirement), load voltage capability to 264V (exceeding the original 75–132V range), and increased load current capacity to 2A. The product is active and RoHS compliant. The wider input voltage range and higher current rating provide design flexibility for applications requiring future scaling.

AQG12105 (Panasonic Electric Works, Similar Alternative)

This part provides direct electrical equivalence to the G3MC-101P DC5: identical input voltage (4–6VDC), identical load current (1A), and identical circuit configuration. Load voltage capability extends to 264V. The product is active, ROHS3 compliant, and REACH unaffected. This option is suitable for direct replacement in applications with strict input voltage and current specifications.

AQG12205 (Panasonic Electric Works, Similar Alternative)

This part matches the AQG12105 in electrical specifications with identical input voltage (4–6VDC) and load current (1A). Load voltage capability extends to 264V. The product is active and ROHS3 compliant. Output type is specified as AC without explicit zero-cross notation. This option is suitable for applications where zero-cross switching is not a critical requirement.

Frequently Asked Questions (FAQ)

Q: Can the G3CN-202P1-US DC3-28 be used as a direct replacement for the G3MC-101P DC5?

A: Yes. The G3CN-202P1-US DC3-28 maintains identical circuit configuration (SPST-NO), package format (4-SIP), mounting type (through hole), and termination style (PC pin). The expanded input voltage range (3–28VDC) and increased load current (2A) are backward compatible with the original 4–6VDC input and 1A load specifications. The extended load voltage range (75–264V) exceeds the original 75–132V requirement.

Q: What is the difference between the Panasonic AQG12105 and AQG12205?

A: Both parts share identical electrical specifications: 4–6VDC input, 1A load current, and 75–264V load voltage range. The primary difference is output type specification. The AQG12105 explicitly specifies AC with zero-cross switching, while the AQG12205 specifies AC output type without explicit zero-cross notation. Selection depends on whether zero-cross switching is required for the application.

Q: Are all substitute parts available in the same package format?

A: Yes. The G3MC-101P DC5 and all three substitute parts (G3CN-202P1-US DC3-28, AQG12105, AQG12205) are configured in 4-SIP packages with through-hole PC pin termination, ensuring mechanical and electrical compatibility on existing PCB layouts.

Q: What compliance certifications apply to the substitute parts?

A: The G3CN-202P1-US DC3-28 is RoHS compliant. The AQG12105 and AQG12205 are ROHS3 compliant and REACH unaffected. All three substitute parts meet current regulatory requirements for electronic component deployment.

Q: Can the G3CN-202P1-US DC3-28 be used in applications requiring exactly 4–6VDC input?

A: Yes. Although the G3CN-202P1-US DC3-28 accepts input voltage from 3–28VDC, it operates correctly within the 4–6VDC range. The wider input specification does not affect operation at the narrower voltage range.
