Parameter Comparison

Engineering Selection Recommendations

The substitute part 1-794467-1 provides direct functional equivalence to the obsolete 794467-1 connector. Selection of the substitute part is based on the following engineering criteria:

Product Status Consideration: The main part 794467-1 carries an obsolete status, indicating discontinued manufacturing and limited availability. The substitute part 1-794467-1 maintains active product status, ensuring ongoing availability and supply chain continuity for new designs and production requirements.

Compliance and Certification: The substitute part 1-794467-1 achieves RoHS compliance, whereas the main part is RoHS non-compliant. This distinction is significant for applications subject to RoHS directives and environmental regulations. Both parts maintain identical electrical and mechanical specifications, including UL94 V-0 flammability rating and 600VAC voltage rating.

Contact Finish Specification: The substitute part features a tin contact finish on both mating and post surfaces, compared to the tin-lead finish on the main part. Tin finishes are compatible with solder termination processes and provide equivalent electrical performance within the specified operating temperature range of -55°C to 105°C.

Functional Interchangeability: All mechanical parameters, including pitch, row spacing, shrouding configuration, and fastening mechanism, are identical between the main and substitute parts. The connector maintains the same through-hole mounting configuration and locking ramp fastening system, ensuring direct board-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can the substitute part 1-794467-1 be used as a direct replacement for the obsolete 794467-1?

A: Yes. The substitute part maintains identical mechanical and electrical specifications across all critical parameters, including connector type, contact configuration, pitch, row spacing, mounting type, shrouding, and fastening mechanism. The parts are functionally interchangeable at the board level.

Q: What is the difference between the tin-lead finish on the main part and the tin finish on the substitute?

A: The main part features a tin-lead contact finish, while the substitute part uses a tin finish. Both finishes are compatible with solder termination processes and provide equivalent electrical conductivity and performance within the specified operating temperature range. The tin finish on the substitute part aligns with modern RoHS compliance requirements.

Q: Why is the substitute part RoHS compliant while the main part is not?

A: The substitute part 1-794467-1 was manufactured to meet RoHS directives, which restrict the use of lead and other hazardous substances. The main part 794467-1, being obsolete, was manufactured under earlier standards that permitted lead-based contact finishes. The substitute part's RoHS compliance makes it suitable for applications subject to environmental regulations.

Q: Are there any differences in the electrical performance between the two parts?

A: No. Both parts maintain identical voltage ratings (600VAC), operating temperature ranges (-55°C to 105°C), and material flammability ratings (UL94 V-0). The electrical performance is equivalent across all specified parameters.

Q: What is the significance of the part number change from 794467-1 to 1-794467-1?

A: The part number change reflects a manufacturer revision that maintains the same connector design while updating the product to active status and RoHS compliance. The prefix "1-" indicates the current active revision of the AMP-DUAC series connector.

Q: Can the substitute part be used in existing designs without PCB modifications?

A: Yes. The substitute part maintains identical mechanical dimensions, pitch, row spacing, insulation height, and mounting configuration. No PCB layout modifications are required for direct substitution.

Q: Is the substitute part available in the same packaging as the main part?

A: Both parts are provided with equivalent packaging specifications. The substitute part 1-794467-1 is available in active inventory with 1163 pieces in stock, compared to 998 pieces of the obsolete main part.
