G3MC-201PL DC5 Equivalent & Substitute Parts

Part Overview

The G3MC-201PL DC5 is a solid state relay (SSR) manufactured by Omron Automation and Safety, configured as a SPST-NO (1 Form A) relay in a 4-SIP package. This component switches AC loads up to 1 A at 75–264 V with a 4–6 VDC input signal. The product is classified as obsolete, making identification of equivalent and substitute parts essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the G3MC-201PL DC5 is determined by the following critical parameters:

• Circuit Configuration: SPST-NO (1 Form A) – all substitutes must maintain this switching topology
• Package / Case: 4-SIP – physical and electrical compatibility requires identical package
• Mounting Type: Through Hole – PCB integration method must remain consistent
• Termination Style: PC Pin – connector interface must be preserved
• Voltage – Input: 4–6 VDC – control signal range must be compatible
• Voltage – Load: 75–264 V – output voltage rating must meet or exceed this range
• Output Type: AC – load type must be AC-compatible
• Load Current: Substitutes may equal or exceed the 1 A rating

Two categories of substitutes are identified:

1. MFR Recommended Substitute: G3CN-202PL1 DC5 (Omron) – manufacturer-endorsed upgrade with increased current capacity (2 A)
2. Similar Substitutes: AQG12205 and AQG22105 (Panasonic Electric Works) – functionally equivalent alternatives meeting all critical parameters

Parameter Comparison

Engineering Selection Recommendations

G3CN-202PL1 DC5 is the manufacturer-recommended substitute. As an active Omron product with ROHS3 compliance, it provides direct compatibility with identical electrical and mechanical specifications. The increased load current rating (2 A versus 1 A) represents a design upgrade that maintains backward compatibility while offering enhanced capacity margin.

AQG12205 (Panasonic) provides a direct 1:1 electrical and mechanical equivalent to the G3MC-201PL DC5. This part is suitable for applications where current capacity does not require expansion. ROHS3 compliance and active product status ensure long-term availability.

AQG22105 (Panasonic) offers increased load current capacity (2 A) with the addition of zero-cross switching functionality. This part is appropriate for applications benefiting from reduced EMI and improved load control characteristics. ROHS3 compliance and active product status support procurement continuity.

All three substitutes maintain identical input voltage, output voltage, circuit configuration, package, mounting type, and termination style. Selection should be based on load current requirements and desired switching characteristics.

Frequently Asked Questions (FAQ)

Q: Can the G3CN-202PL1 DC5 directly replace the G3MC-201PL DC5?

A: Yes. The G3CN-202PL1 DC5 maintains identical electrical specifications for input voltage (4–6 VDC), output voltage (75–264 V), circuit configuration (SPST-NO), package (4-SIP), mounting type (Through Hole), and termination style (PC Pin). The increased load current rating (2 A) is a design enhancement that does not affect compatibility.

Q: What is the difference between AQG12205 and AQG22105?

A: Both are Panasonic AQ-G series relays with identical input voltage, output voltage, package, mounting, and termination specifications. AQG12205 is rated for 1 A load current, while AQG22105 is rated for 2 A and includes zero-cross switching functionality for reduced EMI.

Q: Are all substitutes available in the same package?

A: Yes. All substitute parts use the 4-SIP package with PC Pin termination and Through Hole mounting, ensuring direct PCB compatibility without layout modifications.

Q: What compliance certifications apply to these substitutes?

A: G3CN-202PL1 DC5 and both Panasonic parts (AQG12205, AQG22105) are ROHS3 compliant. The original G3MC-201PL DC5 is RoHS compliant. All parts carry EAR99 ECCN classification.

Q: Can I use a 2 A rated substitute in a circuit designed for 1 A?

A: Yes. A higher current rating provides additional safety margin and does not degrade performance in applications requiring 1 A or less. Circuit behavior remains unchanged.

Q: What is zero-cross switching in the AQG22105?

A: Zero-cross switching synchronizes relay activation to the AC voltage zero-crossing point, reducing inrush current and electromagnetic interference. This feature is present in AQG22105 but not in the original G3MC-201PL DC5 or AQG12205.
