TE Connectivity 1-640441-3 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-640441-3 is a 13-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 24 AWG discrete or ribbon cable. This connector features tin-lead contact finish and is classified as RoHS non-compliant. The part remains in active production status with 1029 units currently in stock.

Identification of equivalent and substitute parts becomes necessary when addressing RoHS compliance requirements, managing inventory constraints, or accommodating specific procurement specifications while maintaining identical electrical and mechanical functionality.

Substitute Part Grouping Explanation

Substitution eligibility for the 1-640441-3 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

Connector type (Receptacle)
Number of positions (13)
Pitch specification (0.100" / 2.54mm)
Number of rows (1)
Contact type (Female Socket)
Cable termination method (IDC)
Wire gauge compatibility (24 AWG)
Mounting configuration (Free Hanging In-Line, Right Angle)
Fastening mechanism (Locking Ramp)
Contact finish thickness (80.0µin / 2.03µm)
Closed end feature
Color (White)
Moisture sensitivity level (1)

The substitute part 4-640441-3 maintains complete equivalence across all electrical and mechanical parameters. The primary distinction between the main part and its substitute is the contact finish specification (tin-lead versus tin) and the resulting RoHS compliance status.

Engineering Selection Recommendations

For RoHS3 Compliant Applications: Select part number 4-640441-3. This substitute maintains complete electrical and mechanical equivalence to the 1-640441-3 while meeting ROHS3 compliance requirements through its tin contact finish specification. Both parts share identical connector architecture, pitch, position count, and termination methodology.

For Non-Compliant or Legacy Applications: The 1-640441-3 remains suitable for applications without RoHS compliance mandates. The tin-lead contact finish provides equivalent electrical performance and mechanical compatibility with the substitute part.

Inventory and Packaging Considerations: The 4-640441-3 substitute is available in bulk packaging with higher current inventory (1462 units) compared to the main part (1029 units). Both parts maintain active production status and identical moisture sensitivity ratings.

Frequently Asked Questions (FAQ)

Q: Are the 1-640441-3 and 4-640441-3 electrically interchangeable?

A: Yes. Both parts are 13-position receptacle connectors with identical pitch (0.100"), contact type (female socket), wire gauge (24 AWG), and IDC termination method. Electrical performance is equivalent.

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

A: The contact finish differs: 1-640441-3 uses tin-lead finish (RoHS non-compliant), while 4-640441-3 uses tin finish (ROHS3 compliant). All other electrical and mechanical specifications are identical.

Q: Can I use 4-640441-3 as a direct replacement for 1-640441-3 in existing designs?

A: Yes. The 4-640441-3 maintains complete mechanical and electrical compatibility. The connector dimensions, mounting configuration, fastening mechanism, and cable termination method are identical.

Q: Does the contact finish change affect connector performance?

A: No. Both tin-lead and tin finishes meet the specified contact finish thickness of 80.0µin (2.03µm). Performance characteristics remain equivalent.

Q: What is the significance of the packaging difference?

A: The 1-640441-3 uses standard packaging while the 4-640441-3 uses bulk packaging. This affects order quantities and handling but does not impact connector functionality or compatibility.

Q: Are both parts available in the same series?

A: Yes. Both the 1-640441-3 and 4-640441-3 belong to the TE Connectivity MTA-100 series and maintain active production status.

Q: Which part should I specify for new designs?

A: For new designs subject to RoHS compliance requirements, specify 4-640441-3. For applications without RoHS mandates, either part is acceptable based on availability and procurement requirements.
