TE Connectivity 644465-2 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 644465-2 is a 2-position rectangular receptacle connector from the MTA-156 series, designed for IDC (Insulation Displacement Contact) termination with 18 AWG discrete or ribbon cable. This connector features a tin-lead contact finish, feed-through capability, and polarizing key for secure mating.

The 644465-2 is classified as obsolete. Locating equivalent substitute parts is necessary to support ongoing maintenance, repair, and production requirements where this connector is specified in existing designs or legacy systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 644465-2 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type (Receptacle)
• Number of positions (2)
• Pitch (0.156" / 3.96mm)
• Number of rows (1)
• Contact type (Female Socket)
• Cable termination method (IDC)
• Wire gauge (18 AWG)
• Mounting type (Free Hanging In-Line)
• Fastening type (Locking Ramp)
• Features (Feed Through, Polarizing Key)
• Contact finish thickness (80.0µin / 2.03µm)
• Color (Orange)
• Series (MTA-156)

The substitute part 3-644465-2 maintains full equivalence across all these parameters. The primary difference is the contact finish material (tin versus tin-lead) and product status (active versus obsolete).

Parameter Comparison

Engineering Selection Recommendations

The 3-644465-2 is the direct substitute for the obsolete 644465-2. Both parts are manufactured by TE Connectivity and belong to the MTA-156 series with identical mechanical and electrical specifications.

Product Status Consideration: The 644465-2 is obsolete, while the 3-644465-2 is active. For new designs, ongoing production, and long-term support, the 3-644465-2 is the appropriate selection.

Compliance Consideration: The 3-644465-2 is RoHS compliant, whereas the 644465-2 is RoHS non-compliant. Applications subject to RoHS regulations require the 3-644465-2. The contact finish difference (tin versus tin-lead) is the primary driver of this compliance distinction.

Availability Consideration: The 3-644465-2 has significantly higher inventory availability (3050 pieces versus 917 pieces), supporting both immediate procurement and supply chain continuity.

Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.8000) classifications and share the same moisture sensitivity level (MSL 1 - Unlimited).

Frequently Asked Questions (FAQ)

Q: Can the 3-644465-2 be used as a direct replacement for the 644465-2?

A: Yes. The 3-644465-2 is mechanically and electrically equivalent to the 644465-2 across all critical parameters including connector type, position count, pitch, contact type, termination method, wire gauge, mounting configuration, and fastening mechanism. Both parts are from the MTA-156 series and are manufactured by TE Connectivity.

Q: What is the difference between the tin-lead finish on the 644465-2 and the tin finish on the 3-644465-2?

A: The contact finish material differs between the two parts. The 644465-2 uses tin-lead, while the 3-644465-2 uses tin. Both finishes maintain the same thickness specification (80.0µin / 2.03µm). The tin finish on the 3-644465-2 enables RoHS compliance.

Q: Why is the 644465-2 listed as obsolete?

A: The 644465-2 is classified as obsolete by TE Connectivity. The 3-644465-2 represents the current active equivalent in the product line and should be used for all new applications and ongoing support.

Q: Are there any packaging differences between these parts?

A: The 644465-2 packaging is not specified in the available data. The 3-644465-2 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance is a regulatory and material composition requirement, not an electrical performance specification. Both parts maintain identical electrical characteristics and contact finish thickness.

Q: What is the inventory status for these parts?

A: The 644465-2 has 917 pieces in stock. The 3-644465-2 has 3050 pieces in stock. For long-term supply assurance, the 3-644465-2 is the preferred selection.

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

A: Yes. Both the 644465-2 and 3-644465-2 support discrete or ribbon cable termination via IDC (Insulation Displacement Contact) at 18 AWG wire gauge.

Q: What does the polarizing key feature provide?

A: The polarizing key ensures correct mating orientation between the receptacle and its corresponding plug connector, preventing incorrect insertion and potential circuit damage.
