Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EAO 61-8570.12 is determined by the following critical parameters:

• Contact rating of 5A @ 250VAC/DC
• Termination style: Solder, Quick Connect - 0.110" (2.8mm)
• Series 61 compatibility
• RoHS3 compliance
• REACH unaffected status

The substitute part 61-8574.12 maintains all required electrical and mechanical parameters while offering active product status and bulk packaging availability.

Parameter Comparison

Engineering Selection Recommendations

The EAO 61-8574.12 is the qualified substitute for the obsolete 61-8570.12. Both parts maintain identical electrical specifications (5A @ 250VAC/DC) and mechanical interface requirements (Solder, Quick Connect - 0.110" termination). The substitute part carries active product status with confirmed inventory availability and maintains full RoHS3 and REACH compliance. The circuit configuration difference (DPST-NO/NC versus standard) does not affect substitution eligibility when the application requirements align with the enhanced switching capability.

Frequently Asked Questions (FAQ)

Q: Can the 61-8574.12 directly replace the 61-8570.12 in existing designs?

A: Yes. Both parts share identical contact ratings (5A @ 250VAC/DC), termination style (Solder, Quick Connect - 0.110"), and Series 61 compatibility. The 61-8574.12 offers DPST-NO/NC circuit configuration, which provides additional switching flexibility while maintaining backward compatibility with applications requiring standard contact block functionality.

Q: What is the significance of the DPST-NO/NC circuit configuration in the substitute part?

A: DPST-NO/NC indicates Double Pole Single Throw with Normally Open/Normally Closed capability. This configuration provides dual-pole switching with selectable contact states, offering greater application flexibility than standard contact blocks while maintaining the same electrical rating and physical interface.

Q: Are there packaging differences between these parts?

A: The 61-8570.12 is supplied in standard packaging, while the 61-8574.12 is available in bulk packaging. Both are suitable for integration into switch body assemblies and maintain identical termination specifications.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the 61-8570.12 and 61-8574.12 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.
