TE Connectivity 640433-5 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640433-5 is a 5-position rectangular receptacle connector from the MTA-156 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 free-hanging, in-line mounted component with closed-end design. The part is currently active in production with 1061 units in stock. Substitute parts are identified to address specific compliance requirements, packaging preferences, or inventory availability while maintaining functional equivalence within the MTA-156 series.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the MTA-156 rectangular connector series is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type (Receptacle)
• Number of positions (5)
• Pitch specification (0.156" / 3.96mm)
• Contact type (Female Socket)
• Cable termination method (IDC)
• Wire gauge (22 AWG)
• Wire type compatibility (Discrete or Ribbon Cable)
• Mounting type (Free Hanging, In-Line)
• Contact finish thickness (80.0µin / 2.03µm)
• Number of rows (1)
• Closed-end design
• Series designation (MTA-156)
• Moisture sensitivity level (1)

The substitute part 3-640433-5 maintains full equivalence across all mandatory parameters. The primary distinction between the main part and its substitute relates to contact finish specification (tin-lead versus tin) and RoHS compliance status, which do not affect mechanical or electrical interchangeability within the specified application parameters.

Parameter Comparison

Engineering Selection Recommendations

640433-5 (Tin-Lead Contact Finish): This part is suitable for applications where tin-lead contact finish is explicitly specified or where RoHS non-compliance is acceptable within the design framework. The part maintains active production status with higher current inventory availability (1061 units).

3-640433-5 (Tin Contact Finish, RoHS Compliant): This substitute part is the appropriate selection for applications requiring RoHS compliance or where tin contact finish is specified. The part is actively produced and maintains adequate inventory (990 units). The tin contact finish with equivalent thickness (80.0µin / 2.03µm) provides equivalent electrical and mechanical performance within the MTA-156 series specifications.

Both parts are manufactured by TE Connectivity AMP Connectors and share identical mechanical and electrical characteristics across all critical parameters. Selection between these parts is determined by regulatory compliance requirements and contact finish specifications rather than functional capability.

Frequently Asked Questions (FAQ)

Q: Are 640433-5 and 3-640433-5 mechanically interchangeable?

A: Yes. Both parts are 5-position rectangular receptacle connectors in the MTA-156 series with identical pitch (0.156" / 3.96mm), mounting type (free hanging, in-line), and closed-end design. They accept the same mating connectors and cable termination methods.

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

A: Both contact finishes are applied at 80.0µin (2.03µm) thickness. The distinction is material composition: 640433-5 uses tin-lead, while 3-640433-5 uses tin. This difference does not affect electrical performance or mechanical compatibility within the specified application parameters.

Q: Which part should be selected for RoHS-compliant applications?

A: The 3-640433-5 is RoHS compliant and is the appropriate selection for applications requiring RoHS compliance. The 640433-5 is RoHS non-compliant.

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

A: Yes. Both parts support discrete or ribbon cable with 22 AWG wire gauge using IDC termination.

Q: What is the significance of the Moisture Sensitivity Level (MSL) rating of 1?

A: MSL 1 indicates unlimited moisture sensitivity, meaning these connectors do not require special moisture control or baking procedures during storage and handling.

Q: Are there packaging differences between these parts?

A: The 640433-5 packaging is not specified in the provided data. The 3-640433-5 is supplied in bulk packaging. Packaging preference may influence selection based on assembly requirements.

Q: What is the current inventory status for each part?

A: 640433-5 has 1061 units in stock. 3-640433-5 has 990 units in stock. Both are new original parts.
