TE Connectivity 640443-5 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640443-5 is a 5-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 28 AWG discrete or ribbon cable. This connector features tin-lead contact finish and is classified as obsolete product status. Due to its obsolete classification, identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for ongoing production and field service applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 640443-5 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Series designation (MTA-100)
• Connector type (Receptacle)
• Number of positions (5)
• Pitch specification (0.100" / 2.54mm)
• Contact type (Female Socket)
• Cable termination method (IDC)
• Wire gauge compatibility (28 AWG)
• Mounting configuration (Free Hanging In-Line, Right Angle)
• Fastening mechanism (Locking Ramp)
• Features (Closed End)

The substitute part 3-640443-5 maintains full electrical and mechanical compatibility with the original 640443-5 across all specified parameters. The primary distinction between these parts is the contact finish specification (tin-lead versus tin) and product status classification (obsolete versus active).

Parameter Comparison

Engineering Selection Recommendations

The substitute part 3-640443-5 is functionally equivalent to the original 640443-5 across all electrical and mechanical parameters. The following factors support substitution:

Product Status: The original 640443-5 carries obsolete status, whereas the substitute 3-640443-5 maintains active product status with significantly higher inventory availability (20,864 pieces versus 1,016 pieces).

Regulatory Compliance: The substitute part 3-640443-5 is RoHS compliant, whereas the original 640443-5 is RoHS non-compliant. This distinction is relevant for applications subject to RoHS directive requirements.

Contact Finish: The original part specifies tin-lead contact finish, while the substitute specifies tin contact finish. Both maintain identical contact finish thickness (80.0µin / 2.03µm). The tin finish in the substitute part aligns with modern manufacturing standards and RoHS compliance requirements.

Mechanical and Electrical Compatibility: All critical parameters including connector type, position count, pitch, contact type, termination method, wire gauge, mounting configuration, and fastening mechanism are identical between the original and substitute parts.

Frequently Asked Questions (FAQ)

Q: Can the 3-640443-5 be used as a direct replacement for the 640443-5 in existing designs?

A: Yes. The 3-640443-5 maintains full electrical and mechanical compatibility with the 640443-5 across all specified parameters including connector type, position count, pitch, contact type, IDC termination, wire gauge, mounting configuration, and fastening mechanism.

Q: What is the difference between the tin-lead finish on the original part and the tin finish on the substitute?

A: Both finishes maintain identical contact finish thickness at 80.0µin (2.03µm). The tin finish on the substitute part represents the current manufacturing standard and supports RoHS compliance requirements.

Q: Why is the original 640443-5 classified as obsolete?

A: The 640443-5 carries obsolete product status. The substitute 3-640443-5 is the active equivalent part from TE Connectivity AMP Connectors and is recommended for new designs and ongoing production.

Q: Are there packaging differences between these parts?

A: The original 640443-5 packaging is not specified in the available data. The substitute 3-640443-5 is supplied in bulk packaging.

Q: What is the inventory status for these parts?

A: The original 640443-5 has 1,016 pieces in stock. The substitute 3-640443-5 has 20,864 pieces in stock, providing significantly greater availability.

Q: Do both parts support the same wire gauge and termination method?

A: Yes. Both parts support 28 AWG wire gauge and IDC (Insulation Displacement Contact) termination for discrete or ribbon cable applications.

Q: Are the regulatory classifications identical for both parts?

A: Both parts share identical ECCN (EAR99) and HTSUS (8536.69.8000) classifications. The substitute part 3-640443-5 is RoHS compliant, whereas the original 640443-5 is RoHS non-compliant.
