TE Connectivity 644083-5 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 644083-5 is a 5-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, closed-end design, and free-hanging or right-angle mounting configuration with locking ramp fastening. The part is currently active in production with 885 pieces available in new original inventory.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across connector specifications. Alternative part numbers may be required due to inventory availability, packaging format changes, or compliance requirement updates while preserving functional compatibility in the application circuit.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 644083-5 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Receptacle)
• Number of positions (5)
• Contact type (Female Socket)
• Pitch spacing (0.100" / 2.54mm)
• Cable termination method (IDC)
• Wire gauge compatibility (22 AWG)
• Wire type support (Discrete or Ribbon Cable)

Mechanical Compatibility Parameters:

• Mounting configuration (Free Hanging In-Line, Right Angle)
• Fastening mechanism (Locking Ramp)
• Closed-end design
• Single-row configuration
• MTA-100 series designation

Physical Parameters:

• Color (Black)
• Moisture Sensitivity Level (1 - Unlimited)

The substitute part 3-644083-5 maintains full equivalence across all electrical and mechanical parameters. Variations in contact finish material (tin versus tin-lead), contact finish thickness consistency, packaging format, RoHS compliance status, and HTSUS classification do not affect functional interchangeability in the application circuit.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (644083-5): The TE Connectivity 644083-5 is suitable for applications where tin-lead contact finish is specified or required. This part maintains active production status and is available in current inventory. Selection of this part is appropriate for legacy system designs or applications with established tin-lead material specifications.

Substitute Part Selection (3-644083-5): The 3-644083-5 provides functional equivalence with ROHS3 compliance certification, making it the appropriate selection for new designs, systems requiring RoHS compliance, or applications subject to environmental regulations restricting lead content. This substitute maintains identical electrical and mechanical performance while offering improved regulatory alignment. Higher inventory availability (1280 pieces) supports production scheduling requirements.

Both parts are manufactured by TE Connectivity AMP Connectors and maintain active product status. Selection between these parts is determined by compliance requirements and contact finish material specifications rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Are the 644083-5 and 3-644083-5 connectors mechanically interchangeable?

A: Yes. Both connectors maintain identical mechanical specifications including 5-position configuration, 0.100" pitch spacing, free-hanging and right-angle mounting options, locking ramp fastening, and closed-end design. Physical dimensions and mounting interfaces are equivalent.

Q: Can the 3-644083-5 substitute for the 644083-5 in existing applications?

A: Yes. The 3-644083-5 maintains full electrical and mechanical equivalence. The primary difference is contact finish material (tin versus tin-lead) and RoHS compliance status. Applications currently using 644083-5 can transition to 3-644083-5 without circuit redesign or connector interface modification.

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

A: The 644083-5 features tin-lead contact finish (80.0µin thickness), while the 3-644083-5 features tin contact finish (80.0µin thickness). Both finishes provide equivalent contact resistance and electrical performance. The tin-lead version is non-compliant with RoHS regulations, while the tin version is ROHS3 compliant. Contact finish thickness is identical for both parts.

Q: Do these connectors support both discrete and ribbon cable termination?

A: Yes. Both the 644083-5 and 3-644083-5 support IDC termination for discrete or ribbon cable at 22 AWG wire gauge. The IDC termination method accommodates both cable types without connector modification.

Q: What is the packaging difference between these parts?

A: The 644083-5 packaging format is not specified in the product data. The 3-644083-5 is supplied in bulk packaging. Packaging format does not affect connector functionality or electrical performance.

Q: Are both parts currently available for procurement?

A: Yes. The 644083-5 has 885 pieces in new original inventory. The 3-644083-5 has 1280 pieces in new original inventory. Both parts maintain active production status.

Q: Which part should be selected for new design implementations?

A: The 3-644083-5 is the appropriate selection for new designs due to ROHS3 compliance certification. This part meets current environmental and regulatory requirements while maintaining full functional equivalence to the 644083-5.
