TE Connectivity 640604-9 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640604-9 is a 9-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 tin-lead contact finish and is classified as obsolete. Due to its obsolete product status and RoHS non-compliant classification, identification of equivalent active alternatives is necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 640604-9 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following areas:

Mandatory Equivalence Parameters:

• Connector type (Rectangular Receptacle)
• Number of positions (9)
• Pitch specification (0.156" / 3.96mm)
• Contact type (Female Socket)
• Cable termination method (IDC)
• Wire gauge compatibility (18 AWG)
• Wire type support (Discrete or Ribbon Cable)
• Mounting configuration (Free Hanging In-Line)
• Series designation (MTA-156)

The substitute part 3-640604-9 meets all mandatory equivalence parameters and is therefore a direct functional substitute for the 640604-9.

Parameter Comparison

Engineering Selection Recommendations

The 3-640604-9 is the direct substitute for the obsolete 640604-9 based on complete electrical and mechanical parameter equivalence within the MTA-156 series.

Primary Advantage: The substitute part 3-640604-9 carries Active product status, ensuring long-term availability and supply chain continuity compared to the Obsolete 640604-9.

Compliance Improvement: The 3-640604-9 is RoHS Compliant, whereas the 640604-9 is RoHS non-compliant. This compliance status aligns with current regulatory requirements for electronic component procurement.

Contact Finish Consideration: The main part features tin-lead contact finish, while the substitute features tin contact finish. Both finishes are applied at identical thickness (80.0µin / 2.03µm) and maintain functional equivalence for IDC termination applications with 18 AWG cable.

Packaging: The substitute is supplied in Bulk packaging, whereas the main part packaging is not specified. This does not affect functional compatibility.

Regulatory Alignment: Both parts share identical ECCN (EAR99) and HTSUS (8536.69.8000) classifications, maintaining consistent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can the 3-640604-9 be used as a direct replacement for the 640604-9?

A: Yes. The 3-640604-9 is a direct functional substitute. All critical electrical and mechanical parameters are identical, including connector type, position count, pitch, contact type, termination method, wire gauge, and mounting configuration.

Q: What is the difference between tin-lead and tin contact finishes in this application?

A: Both finishes are applied at identical thickness (80.0µin / 2.03µm) and are functionally equivalent for IDC termination with 18 AWG cable. The tin finish in the substitute part represents a modern formulation that complies with RoHS requirements.

Q: Why is the 640604-9 marked as Obsolete?

A: The 640604-9 has been discontinued by TE Connectivity. The 3-640604-9 is the active equivalent and is the recommended selection for new designs and ongoing procurement.

Q: Does RoHS compliance affect connector performance?

A: RoHS compliance does not affect electrical or mechanical performance in this connector category. The 3-640604-9 maintains identical functional specifications while meeting current regulatory requirements.

Q: Are there any inventory considerations between these parts?

A: The 640604-9 has 1068 pieces in stock (Obsolete status), while the 3-640604-9 has 651 pieces in stock (Active status). For new procurement, the active part 3-640604-9 is the appropriate selection.

Q: Can discrete wire and ribbon cable both be terminated using these connectors?

A: Yes. Both the 640604-9 and 3-640604-9 support termination of discrete or ribbon cable at 18 AWG using IDC termination method.

Q: What is the pitch specification and why is it important?

A: The pitch is 0.156" (3.96mm), which defines the center-to-center spacing between contact positions. This specification must match exactly for connector compatibility and is identical between the main part and substitute.
