Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EAO 41-264.025 is determined by the following critical parameters:

• Circuit Configuration: 8PST-4NO/4NC (eight pole, single throw with four normally open and four normally closed contacts)
• Current Rating: 5A AC minimum
• Voltage Rating: 250V AC minimum
• Mounting Type: Panel Mount, Front installation
• Termination Style: Solder Lug
• Ingress Protection: IP40 or higher
• RoHS Compliance: ROHS3 Compliant

The EAO 31-264.025 meets all critical electrical and mechanical parameters required for direct substitution. While panel cutout dimensions differ between the main part (rectangular 21.00mm x 15.00mm) and the substitute (circular 16.00mm diameter), both maintain the same mounting classification and electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

The EAO 31-264.025 is the direct electrical equivalent for the obsolete EAO 41-264.025. Both components share identical circuit configuration, current and voltage ratings, mounting classification, and termination style. The substitute part maintains ROHS3 compliance and carries active product status, ensuring continued availability and supply chain reliability.

Panel cutout dimension differences require mechanical evaluation during installation. The substitute part features a circular 16.00mm diameter cutout compared to the main part's rectangular 21.00mm x 15.00mm cutout. This dimensional change necessitates panel modification or adapter consideration for direct replacement in existing installations.

The substitute part provides documented operating temperature range (-25°C ~ 55°C) and mechanical life specification (1,000,000 cycles), parameters not specified for the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can the EAO 31-264.025 directly replace the EAO 41-264.025 in electrical applications?

A: Yes. Both parts share identical electrical specifications: 8PST-4NO/4NC circuit, 5A AC current rating, 250V AC voltage rating, solder lug termination, and IP40 ingress protection. Electrical compatibility is confirmed.

Q: What is the primary difference between these two parts?

A: The main difference is panel cutout geometry. The 41-264.025 requires a rectangular cutout (21.00mm x 15.00mm), while the 31-264.025 requires a circular cutout (16.00mm diameter). Mechanical panel modification may be necessary for installation.

Q: Is the substitute part still in production?

A: Yes. The EAO 31-264.025 carries active product status with documented inventory availability, unlike the obsolete 41-264.025.

Q: Are both parts RoHS compliant?

A: Yes. Both the main part and substitute meet ROHS3 compliance requirements.

Q: What operating conditions are specified for the substitute part?

A: The EAO 31-264.025 operates within -25°C to 55°C temperature range with a mechanical life rating of 1,000,000 cycles.
