G3MC-201P DC5 Equivalent & Substitute Parts

Part Overview

The G3MC-201P 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 operates with a 4–6VDC input and controls AC loads up to 1A at 75–264V with zero-cross switching. The product is classified as obsolete, necessitating identification of equivalent and substitute components for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the G3MC-201P DC5 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
• Voltage - Load: Must support 75 V ~ 264 V range
• Load Current: Must support minimum 1 A
• Output Type: Must be AC with zero-cross capability
• Voltage - Input: Must support 4 ~ 6VDC input range

Substitute parts are grouped into two categories:

MFR Recommended Substitute: G3CN-202P1-US DC3-28 (Omron Automation and Safety) — An active product from the same manufacturer with enhanced input voltage range (3–28VDC) and increased load current capacity (2A), maintaining full compatibility with the mechanical and electrical interface requirements.

Similar Substitutes: AQG12105 and AQG12205 (Panasonic Electric Works) — Active products from an alternative manufacturer that match the original input voltage range (4–6VDC), load current (1A), and all mechanical specifications, providing direct functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

G3CN-202P1-US DC3-28 is the manufacturer-recommended substitute. As an active Omron product, it provides continuity with the original design lineage and maintains full mechanical compatibility. The extended input voltage range (3–28VDC) and increased load current capacity (2A) offer design flexibility without compromising the core 4–6VDC operating point. This option is preferred for new designs and long-term procurement stability.

AQG12105 provides direct functional equivalence to the original G3MC-201P DC5. Manufactured by Panasonic Electric Works, it matches the input voltage range (4–6VDC), load current (1A), and all mechanical specifications. ROHS3 compliance and unlimited MSL rating align with modern environmental standards. This option is suitable for applications requiring exact electrical and mechanical compatibility.

AQG12205 is functionally equivalent to the G3MC-201P DC5 with identical input voltage (4–6VDC), load current (1A), and mechanical specifications. The primary distinction is the output type specification (AC without explicit zero-cross notation). ROHS3 compliance and unlimited MSL rating are provided. This option is applicable where zero-cross switching is not a critical requirement.

Frequently Asked Questions (FAQ)

Q: Can G3CN-202P1-US DC3-28 be used as a direct replacement for G3MC-201P DC5?

A: Yes. The G3CN-202P1-US DC3-28 maintains full mechanical compatibility (4-SIP package, through-hole mounting, PC pin termination) and electrical compatibility (SPST-NO circuit, AC output with zero-cross, 75–264V load voltage). The 4–6VDC input range of the original design operates within the extended 3–28VDC range of the substitute. The increased 2A load current capacity exceeds the original 1A specification, providing additional margin.

Q: What is the difference between AQG12105 and AQG12205?

A: Both parts are manufactured by Panasonic Electric Works and share identical electrical and mechanical specifications for the G3MC-201P DC5 substitution: 4–6VDC input, 1A load current, 75–264V load voltage, 4-SIP package, and through-hole mounting. The documented difference is the output type specification: AQG12105 specifies AC with zero-cross switching, while AQG12205 specifies AC output. Selection between these parts depends on whether zero-cross switching is required for the application.

Q: Are the Panasonic AQG series parts compatible with the original PCB layout?

A: Yes. Both AQG12105 and AQG12205 use the 4-SIP package with PC pin termination, matching the mechanical footprint and pin configuration of the G3MC-201P DC5. No PCB modifications are required for substitution.

Q: What compliance certifications apply to each substitute?

A: G3CN-202P1-US DC3-28 carries EAR99 and HTSUS classifications. AQG12105 and AQG12205 are ROHS3 compliant with REACH Unaffected status and EAR99 / HTSUS classifications. All parts meet RoHS environmental standards applicable to their respective product statuses.

Q: Can these substitutes handle the same load current as the original part?

A: G3CN-202P1-US DC3-28 supports 2A, exceeding the original 1A specification. AQG12105 and AQG12205 both support 1A, matching the original specification. All substitutes are rated for the full 75–264V load voltage range of the original design.
