Key Parameters

Substitute Part Grouping Explanation

Substitution of the AT78041 is determined by strict equivalence across the following parameters:

• Number of Positions: 8 positions (electrical interface requirement)
• Mounting Type: Free Hanging (mechanical form factor)
• Termination Style: Screw Terminal (connection method)
• Type: Socket (functional classification)

The P3G-08 manufactured by Omron Automation and Safety meets all four critical parameters, establishing it as a direct functional equivalent. Both parts interface with multiple relay series and maintain identical electrical and mechanical specifications for socket operation.

Parameter Comparison

Engineering Selection Recommendations

The P3G-08 serves as the direct substitute for the AT78041 based on identical electrical and mechanical specifications. The P3G-08 maintains active product status with current manufacturing availability, whereas the AT78041 is obsolete. Both components satisfy RoHS compliance requirements, with the P3G-08 meeting the more recent ROHS3 standard. Moisture sensitivity classification is equivalent at MSL 1 (Unlimited), indicating no special handling requirements for either component. Export classification remains consistent at EAR99 for both parts.

Frequently Asked Questions (FAQ)

Q: Can the P3G-08 directly replace the AT78041 in existing applications?

A: Yes. Both components share identical specifications for number of positions (8), mounting type (free hanging), termination style (screw terminal), and socket type. No circuit modifications are required.

Q: What is the primary reason for substitution?

A: The AT78041 is obsolete. The P3G-08 is an active product with current manufacturing and inventory availability.

Q: Are there compliance differences between these parts?

A: Both parts are RoHS compliant. The P3G-08 meets ROHS3 compliance, representing a more current regulatory standard. Both maintain EAR99 export classification.

Q: Do moisture sensitivity levels differ?

A: No. Both components are classified at MSL 1 (Unlimited), requiring no special moisture control during storage or handling.

Q: Are packaging considerations relevant to substitution?

A: Both parts are supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility.
