TE Connectivity 1-643813-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-643813-1 is an 11-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 and is classified as a closed-end receptacle with free-hanging or right-angle mounting capability using a locking ramp fastening mechanism. The part is currently active in production with 790 pieces available in new original inventory. Equivalent substitute parts are necessary to address supply chain flexibility, compliance requirements, or packaging preferences while maintaining identical electrical and mechanical functionality.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 4-643813-1 is classified as a direct equivalent to the main part 1-643813-1 based on the following critical parameters that determine substitution eligibility:

Electrical Compatibility Parameters:

• Identical connector type (Receptacle)
• Identical number of positions (11)
• Identical pitch spacing (0.100" / 2.54mm)
• Identical contact type (Female Socket)
• Identical wire gauge rating (22 AWG)
• Identical cable termination method (IDC)

Mechanical Compatibility Parameters:

• Identical mounting type (Free Hanging / Right Angle)
• Identical fastening mechanism (Locking Ramp)
• Identical feature set (Closed End)
• Identical contact finish thickness (80.0µin / 2.03µm)
• Identical color (Red)
• Identical series designation (MTA-100)

Environmental Compatibility Parameters:

• Identical Moisture Sensitivity Level (MSL 1 - Unlimited)

The primary distinction between these parts is the contact finish specification (tin-lead versus tin) and RoHS compliance status. Both parts maintain identical form, fit, and functional characteristics for IDC rectangular connector applications.

Parameter Comparison

Engineering Selection Recommendations

Part 1-643813-1 (Tin-Lead Contact Finish): This part is suitable for applications where tin-lead contact finish is explicitly specified or required by legacy design documentation. The part maintains active production status and is RoHS non-compliant, making it appropriate for non-regulated markets or applications with existing tin-lead specifications.

Part 4-643813-1 (Tin Contact Finish): This part is the preferred selection for new designs and applications subject to RoHS compliance requirements. The tin contact finish with identical thickness (80.0µin / 2.03µm) provides equivalent electrical and mechanical performance while meeting modern regulatory standards. This substitute offers superior supply availability with 1783 pieces in inventory compared to 790 pieces for the main part.

Both parts are active products from TE Connectivity AMP Connectors with identical form, fit, and functional characteristics. Selection between these parts should be based on regulatory compliance requirements and contact finish specifications rather than electrical or mechanical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can 4-643813-1 be used as a direct replacement for 1-643813-1 in existing designs?

A: Yes. The 4-643813-1 is a direct functional equivalent with identical connector type, position count, pitch, mounting configuration, and IDC termination method. The primary difference is the contact finish (tin versus tin-lead) and RoHS compliance status. Both parts maintain the same 80.0µin contact finish thickness and are suitable for 22 AWG discrete or ribbon cable applications.

Q: What is the significance of the contact finish difference between these parts?

A: The contact finish difference (tin-lead versus tin) reflects regulatory compliance evolution. The 4-643813-1 with tin finish is RoHS compliant, while the 1-643813-1 with tin-lead finish is RoHS non-compliant. Both finishes provide equivalent electrical conductivity and mechanical durability at the specified thickness of 80.0µin (2.03µm).

Q: Are there packaging differences between these substitute parts?

A: The 1-643813-1 is supplied in standard packaging, while the 4-643813-1 is supplied in bulk packaging. Both parts are identical in form and function; packaging differences do not affect connector performance or compatibility.

Q: Which part should be selected for new product designs?

A: The 4-643813-1 is the appropriate selection for new designs due to RoHS compliance status and superior inventory availability (1783 pieces versus 790 pieces). This part meets current regulatory requirements while maintaining identical electrical and mechanical specifications.

Q: Are both parts suitable for IDC termination with 22 AWG ribbon cable?

A: Yes. Both the 1-643813-1 and 4-643813-1 are rated for IDC termination with 22 AWG discrete or ribbon cable. The IDC termination method, wire gauge rating, and closed-end feature are identical across both parts.

Q: What is the pitch spacing for these 11-position connectors?

A: Both parts feature 0.100" (2.54mm) pitch spacing, which is the standard spacing for MTA-100 series rectangular connectors. This pitch is maintained across all 11 positions in a single-row configuration.

Q: Can these connectors be mounted in both in-line and right-angle orientations?

A: Yes. Both the 1-643813-1 and 4-643813-1 support free-hanging mounting in both in-line and right-angle configurations. The locking ramp fastening mechanism is identical on both parts.
