TE Connectivity 644563-2 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 644563-2 is a 2-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. Due to its obsolete product status and RoHS non-compliant classification, identification of equivalent substitute parts is necessary for ongoing design support, maintenance, and new procurement activities.

Engineering Selection Recommendations

Primary Substitute: 3-644563-2

The part 3-644563-2 is the direct equivalent substitute for 644563-2. Selection of this substitute is based on the following engineering factors:

Product Status Consideration: The main part 644563-2 carries obsolete status, indicating discontinued manufacturing and limited long-term availability. The substitute 3-644563-2 maintains active product status with significantly higher inventory availability (46,999 pieces versus 868 pieces), ensuring supply chain continuity.

Compliance Status: The main part is RoHS non-compliant, while the substitute is RoHS Compliant. This distinction is material for applications subject to RoHS regulations and environmental compliance requirements.

Electrical and Mechanical Equivalence: Both parts maintain identical specifications across all critical parameters including connector type, position count, pitch, termination method, wire gauge, and mounting configuration. The contact finish variation from tin-lead to tin represents a lead-free upgrade that maintains electrical performance and contact reliability.

Certification Alignment: Both parts share identical ECCN (EAR99), HTSUS code (8536.69.8000), and moisture sensitivity classification, confirming regulatory and handling equivalence.

Frequently Asked Questions (FAQ)

Q: Can 3-644563-2 be used as a direct replacement for 644563-2 in existing designs?

A: Yes. The 3-644563-2 maintains complete electrical and mechanical compatibility with 644563-2. All critical parameters including connector type, position count, pitch, IDC termination, wire gauge, and mounting configuration are identical. The contact finish change from tin-lead to tin does not affect functional compatibility.

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

A: The main part uses tin-lead contact finish, while the substitute uses tin (lead-free) finish. Both finishes provide equivalent electrical conductivity and contact reliability at the specified contact finish thickness of 80.0µin (2.03µm). The tin finish represents a lead-free upgrade aligned with RoHS compliance requirements.

Q: Why is the substitute part listed as active while the main part is obsolete?

A: Product status reflects manufacturing lifecycle. The 644563-2 has been discontinued (obsolete), while 3-644563-2 remains in active production. This distinction affects availability and long-term supply assurance. The substitute offers superior procurement viability with substantially higher inventory levels.

Q: Are there packaging differences between these parts?

A: The main part 644563-2 packaging is not specified in available documentation. The substitute 3-644563-2 is supplied in bulk packaging. Packaging format does not affect connector performance or compatibility.

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

A: Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity constraints. This rating permits unlimited shelf life and storage without desiccant requirements, simplifying inventory management and component handling.

Q: Are both parts subject to the same regulatory classifications?

A: Yes. Both parts share identical ECCN (EAR99) and HTSUS code (8536.69.8000) classifications, confirming equivalent regulatory treatment for export control and tariff purposes.
