Key Parameters

Substitute Part Grouping Explanation

Substitution of the 794664-6 connector is based on strict electrical and mechanical parameter alignment. The following parameters define substitution eligibility:

Critical Matching Parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 6
• Number of Rows: 2
• Pitch - Mating: 0.165" (4.20mm)
• Row Spacing - Mating: 0.165" (4.20mm)
• Mounting Type: Through Hole
• Shrouding: Shrouded - 4 Wall
• Voltage Rating: 600VAC
• Operating Temperature Range: -55°C ~ 105°C
• Insulation Material: Polyamide (PA), Nylon
• Material Flammability Rating: UL94 V-2

Substitute parts must maintain identical mechanical footprint, electrical performance, and environmental specifications. Variations in contact finish composition (Tin-Lead versus Tin) are permissible when all other parameters remain constant, as these represent manufacturing process improvements rather than functional changes.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1586491-6 connector serves as a direct functional substitute for the obsolete 794664-6 model. Both connectors maintain identical mechanical and electrical specifications, ensuring pin-for-pin compatibility and interchangeability in existing circuit board designs.

Primary Selection Basis:

The 1586491-6 is classified as an active product, whereas the 794664-6 is obsolete. This status difference alone necessitates transition to the substitute part for new procurement and long-term supply chain continuity.

Compliance Advantages:

The 1586491-6 demonstrates improved regulatory compliance posture. It is ROHS3 compliant and carries REACH Unaffected status, compared to the main part's RoHS non-compliant designation and vendor-undefined REACH status. These certifications align with current environmental and regulatory requirements in electronics manufacturing.

Contact Finish Specification:

The substitute part utilizes pure Tin contact finish on both mating and post surfaces, whereas the main part specifies Tin-Lead. Both finishes maintain the same thickness specification of 118.1µin (3.00µm) and are functionally compatible. The Tin finish represents a modern manufacturing standard consistent with lead-free soldering practices.

Electrical and Mechanical Equivalence:

All critical parameters remain identical: 6-position, 2-row configuration with 0.165" (4.20mm) pitch, through-hole mounting, shrouded 4-wall design, 600VAC voltage rating, and -55°C to 105°C operating temperature range. The connector maintains UL94 V-2 flammability rating and polyamide insulation material specifications.

Frequently Asked Questions (FAQ)

Q: Can the 1586491-6 be used as a direct replacement for the 794664-6 in existing designs?

A: Yes. The 1586491-6 maintains identical mechanical footprint, pin configuration, pitch spacing, and electrical ratings. No circuit board redesign or layout modification is required for substitution.

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

A: Both finishes provide equivalent electrical performance and corrosion resistance at the specified thickness of 118.1µin (3.00µm). The Tin finish on the 1586491-6 represents current manufacturing practice aligned with lead-free soldering standards. Functional compatibility is maintained.

Q: Why is the 794664-6 listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured or supported by TE Connectivity. The 1586491-6 represents the active equivalent in the AMP-DUAC series, ensuring continued availability and supply chain support.

Q: Are there any environmental or regulatory differences between these parts?

A: The 1586491-6 is ROHS3 compliant and REACH Unaffected, whereas the 794664-6 is RoHS non-compliant with vendor-undefined REACH status. For applications subject to environmental regulations or customer compliance requirements, the 1586491-6 is the appropriate selection.

Q: What is the operating temperature range for both connectors?

A: Both the 794664-6 and 1586491-6 operate across the identical temperature range of -55°C to 105°C, ensuring thermal performance equivalence across industrial and commercial applications.

Q: Are the voltage and current ratings identical?

A: Both connectors are rated for 600VAC. Current rating specifications are not provided in the technical documentation for either part.

Q: What mounting method is used for both connectors?

A: Both connectors utilize through-hole solder termination with locking ramp fastening type, ensuring secure mechanical and electrical connection to printed circuit boards.

Q: Is the 1586491-6 available in the same packaging as the 794664-6?

A: Packaging specifications are not provided in the technical documentation for either part. Contact the manufacturer or authorized distributor for packaging configuration details.
