TE Connectivity 1-643813-6 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-643813-6 is a 16-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 22 AWG discrete or ribbon cable. This connector features tin-lead contact finish, a closed-end design, and a locking ramp fastening mechanism. The part is currently active in production with 798 units in stock.

Substitute parts are identified to address specific application requirements, including RoHS compliance status and packaging variations, while maintaining identical electrical and mechanical interface specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 1-643813-6 is determined by strict equivalence across the following critical parameters:

Electrical Interface Requirements:

• 16-position configuration
• 0.100" (2.54mm) pitch spacing
• Single-row layout
• Female socket contact type
• IDC termination compatibility with 22 AWG wire

Mechanical Interface Requirements:

• Free hanging (in-line) and right-angle mounting capability
• Locking ramp fastening mechanism
• Closed-end connector design
• Red color designation

Environmental & Compliance Parameters:

• Moisture Sensitivity Level 1 (unlimited shelf life)
• Contact finish thickness of 80.0µin (2.03µm)

The substitute part 4-643813-6 maintains complete equivalence across all electrical and mechanical parameters. The primary distinction between the main part and its substitute is the contact finish material (tin-lead versus tin) and RoHS compliance status, which do not affect physical or electrical interface compatibility.

Parameter Comparison

Engineering Selection Recommendations

Part 1-643813-6 (Tin-Lead Contact Finish):

• Select for applications where RoHS non-compliance is acceptable or not required
• Suitable for legacy systems and non-regulated environments
• Current inventory: 798 units

Part 4-643813-6 (Tin Contact Finish):

• Select for applications requiring ROHS3 compliance
• Suitable for regulated industries and new product designs
• REACH Unaffected status provides additional compliance clarity
• Higher inventory availability: 1751 units
• Bulk packaging configuration

Both parts maintain identical electrical and mechanical interface specifications. Selection between them is determined solely by regulatory compliance requirements and packaging preferences, not by functional performance or connector compatibility.

Frequently Asked Questions (FAQ)

Q: Are the 1-643813-6 and 4-643813-6 physically interchangeable?

A: Yes. Both connectors share identical mechanical dimensions, pitch spacing (0.100"), mounting configuration, and fastening mechanism. They are direct physical substitutes with no modification required for installation.

Q: What is the difference between tin-lead and tin contact finishes in these connectors?

A: The contact finish material differs between the two parts. The 1-643813-6 uses tin-lead, while the 4-643813-6 uses tin. Both finishes provide the same contact thickness of 80.0µin (2.03µm) and are compatible with 22 AWG IDC termination. The primary distinction is regulatory compliance: tin-lead is RoHS non-compliant, while tin is ROHS3 compliant.

Q: Can I use the 4-643813-6 as a direct replacement for the 1-643813-6 in existing designs?

A: Yes, the 4-643813-6 is a direct electrical and mechanical equivalent. It can replace the 1-643813-6 without any design modifications. The substitution is particularly beneficial if your application requires RoHS compliance.

Q: What does "Closed End" mean for these connectors?

A: Closed-end design indicates that the connector housing has sealed ends, preventing accidental contact with internal terminals and providing additional protection against environmental contamination.

Q: Are both parts suitable for ribbon cable and discrete wire termination?

A: Yes. Both the 1-643813-6 and 4-643813-6 support IDC termination with either discrete or ribbon cable at 22 AWG wire gauge.

Q: What is the significance of Moisture Sensitivity Level 1?

A: MSL 1 indicates unlimited shelf life with no moisture sensitivity restrictions. Both connectors can be stored and handled without special moisture control measures.

Q: Does the packaging difference (unspecified versus bulk) affect connector performance?

A: No. Packaging is a logistics consideration only and does not affect electrical or mechanical performance. The 4-643813-6 is supplied in bulk packaging, while the 1-643813-6 packaging is not specified in the provided data.

Q: Which part should I select for a new design?

A: If regulatory compliance is a consideration, select the 4-643813-6 (ROHS3 compliant). If compliance is not required and tin-lead contact finish is acceptable, either part is suitable. The 4-643813-6 also offers higher inventory availability.
