Engineering Selection Recommendations

Both the G6K-2G DC4.5 and G6K-2G-Y DC4.5 are active production parts from Omron Electronics. Selection between these parts should be based on the following factors:

G6K-2G DC4.5: Use when standard packaging is acceptable and RoHS Compliance certification is the primary requirement. This part has 651 units in current inventory.

G6K-2G-Y DC4.5: Use when tube packaging is required for automated assembly or handling processes. This part offers ROHS3 Compliant status and REACH Unaffected certification, providing enhanced regulatory documentation. This part has 2444 units in current inventory, offering greater availability.

Both parts are electrically and mechanically identical, ensuring direct substitution in circuit applications without design modification.

Frequently Asked Questions (FAQ)

Q: Can G6K-2G-Y DC4.5 be used as a direct replacement for G6K-2G DC4.5?

A: Yes. Both parts are electrically and mechanically identical with matching coil voltage, contact configuration, current ratings, switching specifications, and operating parameters. The primary difference is packaging format and RoHS certification level.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the current version of the directive. Both parts meet hazardous substance restrictions for the applications specified.

Q: Does packaging affect circuit performance?

A: No. Tube packaging is a handling and storage format only. It does not affect electrical performance, reliability, or operating characteristics of the relay.

Q: Are there any compatibility issues when switching between these part numbers?

A: No. Identical mounting type (Surface Mount), termination style (J Lead), and all electrical specifications ensure complete compatibility. No PCB layout or circuit modifications are required.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on packaging requirements and inventory availability. The G6K-2G-Y DC4.5 offers higher current inventory (2444 units) and enhanced compliance documentation.
