TE Connectivity 1-640440-2 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-640440-2 is a 12-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 22 AWG discrete or ribbon cable. This connector features tin-lead contact finish and is classified as obsolete. Due to its obsolete product status, identification of equivalent substitute parts is necessary to maintain design continuity and ensure component availability for ongoing production and field service applications.

Parameter Comparison

Engineering Selection Recommendations

The 4-640440-2 serves as the direct substitute for the obsolete 1-640440-2 based on the following engineering criteria:

Product Status Alignment: The 4-640440-2 maintains active product status within the TE Connectivity AMP Connectors portfolio, ensuring continued availability and manufacturing support. The 1-640440-2 is classified as obsolete, making the 4-640440-2 the appropriate replacement for new designs and ongoing production requirements.

Regulatory Compliance: The 4-640440-2 achieves ROHS3 compliance, whereas the 1-640440-2 is RoHS non-compliant. This distinction is significant for applications subject to RoHS directives and environmental regulations. The contact finish material differs between the two parts: the 1-640440-2 uses tin-lead, while the 4-640440-2 uses tin. Both maintain identical contact finish thickness of 80.0µin (2.03µm).

Electrical and Mechanical Equivalence: All critical electrical and mechanical parameters are identical between the two parts, including connector configuration, pitch spacing, contact type, termination method, wire gauge compatibility, and fastening mechanisms. This equivalence ensures direct functional interchangeability in circuit applications.

Inventory and Supply Chain: The 4-640440-2 is available in bulk packaging with significantly higher inventory levels (5706 pieces) compared to the 1-640440-2 (667 pieces), supporting sustained production schedules and reducing supply chain risk.

Frequently Asked Questions (FAQ)

Q: Can the 4-640440-2 be used as a direct replacement for the 1-640440-2 in existing designs?

A: Yes. The 4-640440-2 is electrically and mechanically equivalent to the 1-640440-2. Both connectors share identical position count, pitch spacing, contact configuration, IDC termination method, wire gauge compatibility, and mounting specifications. The primary differences are product status (active versus obsolete) and contact finish material composition (tin versus tin-lead).

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

A: The 1-640440-2 features tin-lead contact finish, while the 4-640440-2 uses tin contact finish. Both maintain the same contact finish thickness of 80.0µin (2.03µm). The tin finish in the 4-640440-2 aligns with ROHS3 compliance requirements, eliminating lead content. The electrical performance and contact resistance characteristics remain equivalent for standard IDC applications.

Q: Why is the 1-640440-2 classified as obsolete?

A: The 1-640440-2 is designated as obsolete within the TE Connectivity product portfolio. The 4-640440-2 represents the current active equivalent, offering improved regulatory compliance and sustained manufacturing support.

Q: Are there packaging differences between these two parts?

A: The 1-640440-2 is supplied without specified packaging designation, while the 4-640440-2 is supplied in bulk packaging. This distinction affects inventory management and procurement processes but does not impact connector functionality or electrical performance.

Q: What is the MSL rating for both connectors?

A: Both the 1-640440-2 and 4-640440-2 carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity limitations for storage or handling. This classification simplifies inventory management and eliminates bake-out requirements prior to assembly.

Q: Are both connectors suitable for ribbon cable and discrete wire termination?

A: Yes. Both connectors support IDC termination for discrete or ribbon cable configurations at 22 AWG wire gauge. The IDC mechanism and contact design are identical between the two parts.

Q: What is the pitch spacing for these connectors?

A: Both connectors feature 0.100" (2.54mm) pitch spacing in a single-row, 12-position configuration. This standard pitch is compatible with MTA-100 series mating connectors and cable assemblies.
