Parameter Comparison

Engineering Selection Recommendations

G3MC-202P DC12 (Omron Automation and Safety): This direct substitute maintains identical electrical and mechanical specifications to the G3MB-202P DC12 within the same manufacturer family. Both parts are classified as obsolete. The G3MC-202P DC12 carries RoHS Compliant certification, providing regulatory advantage over the main part. Inventory availability is 798 units.

AQG22112 (Panasonic Electric Works): This substitute meets all electrical and mechanical parameter requirements and is classified as active product status, ensuring continued long-term availability and support. The AQG22112 carries ROHS3 Compliant certification. Inventory availability is 2292 units, the highest among all options.

Selection between G3MC-202P DC12 and AQG22112 should prioritize product status and long-term supply chain stability. The AQG22112 active status supports extended system lifecycles and future procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the G3MC-202P DC12 be used as a direct replacement for the G3MB-202P DC12?

A: Yes. Both parts share identical electrical specifications (9.6–14.4VDC input, 75–264V load voltage, 2A load current), circuit configuration (SPST-NO), output type (AC, zero-cross), package type (4-SIP), and termination style (PC pin). Both are through-hole mounted with MSL 1 rating.

Q: What is the advantage of selecting the AQG22112 over Omron alternatives?

A: The AQG22112 is classified as active product status, ensuring continued manufacturer support and availability. Both Omron options (G3MB-202P DC12 and G3MC-202P DC12) are obsolete. The AQG22112 also provides the highest inventory availability at 2292 units and carries ROHS3 Compliant certification.

Q: Are there any differences in package or mounting between these substitutes?

A: No. All three parts use identical 4-SIP packaging, through-hole mounting, and PC pin termination. They are mechanically and electrically interchangeable within the specified parameter ranges.

Q: What compliance certifications apply to each part?

A: G3MB-202P DC12 carries REACH Unaffected status. G3MC-202P DC12 is RoHS Compliant. AQG22112 is ROHS3 Compliant. All three carry ECCN EAR99 classification and share identical HTSUS codes or equivalent classifications.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes, provided the PCB footprint accommodates the 4-SIP package with PC pin termination and through-hole mounting. No circuit modifications are required due to parameter equivalence.
