G3MC-101P DC12 Equivalent & Substitute Parts

Part Overview

The G3MC-101P 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 with through-hole termination. This component operates with a 9.6–14.4 VDC input and controls AC loads up to 1 A at 75–132 V with zero-cross switching. The product is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations.

Substitute Part Grouping Explanation

Substitution for the G3MC-101P DC12 is determined by the following critical parameters:

• Circuit Configuration: SPST-NO (1 Form A) topology must be maintained
• Package / Case: 4-SIP form factor with through-hole PC pin termination
• Input Voltage Range: 9.6–14.4 VDC compatibility
• Load Current Capability: Minimum 1 A at rated voltage
• Output Type: AC switching with zero-cross capability
• Load Voltage Range: Minimum 75 V support; extended range acceptable

Substitute parts are grouped into two categories:

1. MFR Recommended: G3CN-202P1-US DC3-28 (Omron) – Active product with enhanced specifications
2. Similar Alternatives: AQG12112 and AQG12212 (Panasonic Electric Works) – Active products with equivalent core functionality

All substitutes maintain the 4-SIP package, SPST-NO circuit, and through-hole termination. Load current and voltage ranges vary; selection depends on application requirements.

Parameter Comparison

Engineering Selection Recommendations

G3CN-202P1-US DC3-28 is the manufacturer-recommended substitute. As an active Omron product, it provides continuity within the same manufacturer ecosystem. It supports the original 9.6–14.4 VDC input range and exceeds load specifications with 2 A capability and extended load voltage range (75–264 V). RoHS compliance is maintained.

AQG12112 and AQG12212 (Panasonic Electric Works) are functionally equivalent alternatives. Both maintain the 1 A load current of the original part, support the 9.6–14.4 VDC input range, and extend load voltage capability to 264 V. Both are active products with RoHS compliance. AQG12212 carries ROHS3 certification. The distinction between these two Panasonic alternatives lies in output type specification: AQG12112 explicitly includes zero-cross switching, while AQG12212 specifies AC output without explicit zero-cross notation.

Selection among substitutes depends on:

• Manufacturer preference (Omron continuity vs. Panasonic alternatives)
• Load current requirements (1 A vs. 2 A capability)
• Load voltage range requirements (132 V vs. 264 V maximum)
• Zero-cross switching necessity for the application

Frequently Asked Questions (FAQ)

Q: Can G3CN-202P1-US DC3-28 directly replace G3MC-101P DC12?

A: Yes. Both devices share SPST-NO circuit configuration, 4-SIP package, through-hole termination, and support the 9.6–14.4 VDC input range. G3CN-202P1-US DC3-28 exceeds the original specifications with 2 A load current and 75–264 V load voltage range, making it a compatible upgrade.

Q: What is the difference between AQG12112 and AQG12212?

A: Both are Panasonic Electric Works AQ-G series devices with identical electrical specifications (1 A, 9.6–14.4 VDC input, 75–264 V load voltage). The primary difference is output type specification: AQG12112 explicitly includes zero-cross switching, while AQG12212 specifies AC output. Both use 4-SIP packages with through-hole termination.

Q: Are all substitutes compatible with the original 4-SIP package footprint?

A: Yes. G3MC-101P DC12, G3CN-202P1-US DC3-28, AQG12112, and AQG12212 all use 4-SIP packages with PC pin through-hole termination, ensuring mechanical and electrical compatibility on existing PCBs.

Q: Does the extended load voltage range of substitutes affect compatibility?

A: No. Extended load voltage range (75–264 V vs. original 75–132 V) represents enhanced capability. Substitutes operate within the original voltage specification and support higher voltages if required by the application.

Q: Which substitute should be selected for new designs?

A: G3CN-202P1-US DC3-28 is recommended for new designs as the active manufacturer-recommended product. For cost or availability considerations, AQG12112 or AQG12212 provide equivalent functionality with active product status and current RoHS certification.
