Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector headers is determined by strict equivalence across electrical and mechanical parameters. The primary substitution criteria for the 794468-1 include:

Critical Matching Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Position count (8 positions)
• Row configuration (2 rows)
• Mating pitch (0.165" / 4.20mm)
• Row spacing (0.165" / 4.20mm)
• Mounting method (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening mechanism (Locking Ramp)
• Operating temperature range (-55°C ~ 105°C)
• Voltage rating (600VAC)
• Flammability rating (UL94 V-0)
• Series designation (AMP-DUAC)

Substitute parts must maintain identical values across all these parameters to ensure functional and mechanical compatibility with existing PCB designs and mating connectors.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 1-794468-1 is functionally equivalent to the main part 794468-1 across all critical electrical and mechanical parameters. The primary distinction between these components is product status and regulatory compliance.

Product Status Consideration: The main part 794468-1 carries an obsolete status, indicating discontinued manufacturing and limited availability. The substitute part 1-794468-1 maintains active product status, ensuring ongoing availability from the manufacturer and access to current production batches.

Regulatory Compliance Differences: The substitute part 1-794468-1 is RoHS Compliant and carries REACH Unaffected status, whereas the main part is RoHS non-compliant with vendor-undefined REACH status. This compliance improvement reflects current environmental and regulatory standards applicable to electronic components.

Contact Finish Specification: The main part features Tin-Lead contact finish on both mating and post surfaces. The substitute part specifies Tin contact finish on both surfaces. Both finishes maintain the specified thickness of 118.1µin (3.00µm) on mating surfaces and are compatible with solder termination processes.

For new designs and ongoing procurement, the substitute part 1-794468-1 is the appropriate selection due to active product status and improved regulatory compliance, while maintaining complete functional and mechanical equivalence.

Frequently Asked Questions (FAQ)

Q: Are the 794468-1 and 1-794468-1 mechanically interchangeable?

A: Yes. Both parts share identical mechanical specifications including 8-position, 2-row configuration, 0.165" (4.20mm) pitch, through-hole mounting, shrouded 4-wall construction, and solder termination. PCB footprints and mating connector compatibility are identical.

Q: What is the significance of the contact finish difference between Tin-Lead and Tin?

A: Both finishes are applied at the same thickness (118.1µin / 3.00µm) and are compatible with solder termination processes. The Tin finish on the substitute part reflects current RoHS compliance requirements, while the Tin-Lead finish on the main part represents legacy specifications.

Q: Why is the main part listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production of part number 794468-1. The substitute part 1-794468-1 represents the current active equivalent within the AMP-DUAC series.

Q: Can the 1-794468-1 be used as a direct replacement in existing designs?

A: Yes. The substitute part maintains all critical electrical and mechanical parameters required for direct substitution. Existing PCB designs, mating connectors, and assembly processes remain compatible.

Q: What is the inventory availability difference?

A: The main part 794468-1 has 895 pieces in stock. The substitute part 1-794468-1 has 1065 pieces in stock. Both represent current inventory levels for new original components.

Q: Are there any temperature or voltage rating differences?

A: No. Both parts operate across the identical temperature range of -55°C to 105°C and maintain a 600VAC voltage rating. UL94 V-0 flammability rating is consistent across both parts.

Q: What does RoHS Compliant status mean for the substitute part?

A: RoHS Compliance indicates the substitute part 1-794468-1 meets Restriction of Hazardous Substances directives, restricting lead and other hazardous materials. This is required for many applications and markets, particularly in Europe and regulated industries.
