TE Connectivity 644465-5 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 644465-5 is a 5-position rectangular receptacle connector from the MTA-156 series, designed for IDC (Insulation Displacement Contact) termination with 18 AWG discrete or ribbon cable. This connector features a tin-lead contact finish, polarizing key, and feed-through capability, with free-hanging in-line mounting via locking ramp fastening. The part is currently active in production with 844 pieces in stock inventory.

Substitute parts are identified when equivalent electrical and mechanical specifications are maintained across connector type, position count, pitch, termination method, wire gauge, and mounting configuration. Identifying qualified substitutes is necessary to address supply chain flexibility, compliance requirements, and packaging preferences while maintaining functional interchangeability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 644465-5 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (5)
• Pitch (0.156" / 3.96mm)
• Number of rows (1)
• Cable termination method (IDC)
• Wire gauge (18 AWG)
• Wire type (Discrete or Ribbon Cable)

Mechanical Compatibility Parameters:

• Mounting type (Free Hanging In-Line)
• Fastening type (Locking Ramp)
• Features (Feed Through, Polarizing Key)
• Contact finish thickness (80.0µin / 2.03µm)
• Color (Orange)
• Series designation (MTA-156)

Environmental Parameters:

• Moisture Sensitivity Level (1 - Unlimited)

The substitute part 3-644465-5 maintains full equivalence across all electrical and mechanical parameters. The primary distinction is the contact finish specification (tin versus tin-lead) and corresponding compliance certifications, which do not affect functional interchangeability in the connector interface.

Parameter Comparison

Engineering Selection Recommendations

644465-5 Selection Criteria: The 644465-5 is appropriate for applications where tin-lead contact finish is specified or required by design documentation. This part is RoHS non-compliant and carries REACH Affected status. Selection of this part should be based on explicit design requirements or legacy system compatibility where tin-lead contact properties are necessary.

3-644465-5 Selection Criteria: The 3-644465-5 is the preferred substitute for new designs and applications requiring RoHS compliance. This part maintains full electrical and mechanical equivalence while providing RoHS Compliant certification. The tin contact finish meets modern environmental and regulatory standards. Higher inventory availability (923 pieces versus 844 pieces) provides additional supply chain advantage. This part is suitable for direct substitution in applications where RoHS compliance is required or preferred.

Compliance Considerations: Selection between these parts should be driven by regulatory requirements and design compliance mandates. The 3-644465-5 is recommended for applications subject to RoHS directives or where lead-free components are specified. The 644465-5 remains valid for applications explicitly requiring tin-lead contact finish or where legacy compatibility is necessary.

Frequently Asked Questions (FAQ)

Q: Are the 644465-5 and 3-644465-5 electrically interchangeable?

A: Yes. Both parts are electrically equivalent. They share identical connector type, contact type, position count, pitch, termination method, wire gauge, and contact finish thickness. The contact finish material differs (tin-lead versus tin), but this does not affect electrical interchangeability in the connector interface.

Q: What is the primary difference between these two parts?

A: The primary difference is the contact finish specification and corresponding compliance certifications. The 644465-5 features tin-lead contact finish and is RoHS non-compliant. The 3-644465-5 features tin contact finish and is RoHS Compliant. Both maintain identical mechanical and electrical performance characteristics.

Q: Can I substitute 3-644465-5 for 644465-5 in an existing design?

A: Substitution is mechanically and electrically valid. However, design documentation and compliance requirements must be reviewed. If the original design specifies tin-lead contact finish or is not subject to RoHS requirements, substitution should be evaluated against design specifications. If RoHS compliance is required or preferred, the 3-644465-5 is the appropriate choice.

Q: Does the packaging difference affect compatibility?

A: No. The packaging difference (unspecified for 644465-5 versus Bulk for 3-644465-5) does not affect connector functionality or interchangeability. Packaging affects handling, storage, and ordering logistics but not electrical or mechanical performance.

Q: Are both parts currently in production?

A: Yes. Both the 644465-5 and 3-644465-5 are listed as Active product status with current inventory availability. The 3-644465-5 has higher inventory (923 pieces) compared to the 644465-5 (844 pieces).

Q: What does MSL 1 (Unlimited) mean for these connectors?

A: Moisture Sensitivity Level 1 indicates the lowest moisture sensitivity classification. These connectors have unlimited shelf life and do not require special moisture control during storage or handling. No baking or desiccant storage is required.

Q: Can these connectors be used with both discrete and ribbon cable?

A: Yes. Both parts support discrete or ribbon cable termination via IDC (Insulation Displacement Contact) method at 18 AWG wire gauge. The connector accommodates either termination type without modification.
