TE Connectivity 640441-3 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640441-3 is a 3-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 obsolete product status.

Due to its obsolete classification, locating original stock of the 640441-3 presents supply chain challenges. An active equivalent part is available that maintains functional compatibility while offering improved compliance status and current manufacturing availability.

Substitute Part Grouping Explanation

Substitution of the 640441-3 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

Number of positions: 3
Pitch spacing: 0.100" (2.54mm)
Contact type: Female socket
Wire gauge: 24 AWG
Cable termination: IDC method

Mechanical Compatibility Parameters:

Connector type: Rectangular receptacle
Mounting configuration: Free hanging (in-line), right angle
Fastening mechanism: Locking ramp
Features: Closed end
Color: White
Series designation: MTA-100

Environmental & Compliance Parameters:

Moisture sensitivity level: 1 (unlimited)
Contact finish thickness: 80.0µin (2.03µm)

The substitute part 3-640441-3 maintains identical specifications across all electrical and mechanical parameters. The primary differences are contact finish composition (tin versus tin-lead) and product status (active versus obsolete).

Engineering Selection Recommendations

For New Designs and Procurement:

The 3-640441-3 is the appropriate selection for all new applications. This part maintains complete functional and mechanical equivalence to the 640441-3 while offering active product status and ROHS3 compliance. Current manufacturing availability and higher inventory levels (2300 pcs) support reliable supply chain planning.

For Legacy System Maintenance:

The 640441-3 remains functionally compatible with existing installations. However, the transition to 3-640441-3 is supported by identical electrical and mechanical specifications. The contact finish change from tin-lead to tin does not affect connector performance within the specified parameters.

Compliance Considerations:

The 640441-3 is RoHS non-compliant and REACH affected. The 3-640441-3 achieves ROHS3 compliance, making it the required choice for applications subject to RoHS directives or customer compliance requirements.

Frequently Asked Questions (FAQ)

Q: Are the 640441-3 and 3-640441-3 directly interchangeable?

A: Yes. Both connectors share identical specifications for number of positions (3), pitch (0.100"), contact type (female socket), wire gauge (24 AWG), mounting configuration, and fastening mechanism. They are mechanically and electrically compatible.

Q: What is the difference between tin-lead and tin contact finish?

A: The 640441-3 features tin-lead contact finish, while the 3-640441-3 features tin contact finish. Both maintain the same contact finish thickness of 80.0µin (2.03µm). The contact finish composition does not affect connector function within the specified electrical and mechanical parameters.

Q: Why is the 640441-3 classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The 3-640441-3 serves as the current active equivalent from TE Connectivity.

Q: Can I use the 3-640441-3 in place of the 640441-3 in existing designs?

A: Yes. The 3-640441-3 maintains complete compatibility across all critical parameters: connector type, position count, pitch, contact type, wire gauge, mounting type, and fastening mechanism.

Q: What is the significance of ROHS3 compliance on the 3-640441-3?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements. This is required for applications subject to RoHS regulations or customer specifications. The 640441-3 does not meet this requirement.

Q: Are there packaging differences between these parts?

A: The 640441-3 packaging is not specified in available data. The 3-640441-3 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: What is the MSL rating and why does it matter?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. These connectors can be stored and handled without special moisture control measures.

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

A: Yes. Both the 640441-3 and 3-640441-3 support discrete or ribbon cable termination via IDC method at 24 AWG wire gauge.
