TE Connectivity 640606-5 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640606-5 is a 5-position rectangular receptacle connector from the MTA-156 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 product status.

Due to its obsolete classification, locating direct inventory of the 640606-5 may present supply chain challenges. Identifying equivalent and substitute parts ensures design continuity and maintains system compatibility while accommodating current manufacturing and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 640606-5 is determined by strict equivalence across the following critical parameters:

• Connector Type & Position Count: Receptacle configuration with 5 positions
• Pitch & Row Configuration: 0.156" (3.96mm) pitch, single row layout
• Contact Type & Gender: Female socket contacts
• Cable Termination Method: IDC termination technology
• Wire Gauge Compatibility: 22 AWG rated capacity
• Wire Type Support: Discrete or ribbon cable accommodation
• Mounting Configuration: Free hanging in-line mounting
• Feed Through Feature: Maintained across substitutes

The substitute part 3-640606-5 maintains identical electrical and mechanical specifications across all these parameters, ensuring direct functional equivalence within the MTA-156 series.

Parameter Comparison

Engineering Selection Recommendations

The 3-640606-5 serves as the direct substitute for the obsolete 640606-5 based on the following engineering criteria:

Product Status Alignment: The 3-640606-5 maintains active product status, ensuring ongoing availability and manufacturing support. The 640606-5 is classified as obsolete, creating supply continuity risk.

Compliance Posture: The 3-640606-5 is RoHS compliant, whereas the 640606-5 is RoHS non-compliant. For applications subject to RoHS directives or customer compliance requirements, the 3-640606-5 is the appropriate selection.

Contact Finish Specification: The primary difference between the parts is the contact finish composition. The 640606-5 features tin-lead finish, while the 3-640606-5 features tin finish. Both maintain identical contact finish thickness of 80.0µin (2.03µm), ensuring equivalent electrical performance and contact resistance characteristics.

Electrical and Mechanical Equivalence: All functional parameters—connector type, position count, pitch, row configuration, contact type, termination method, wire gauge, mounting configuration, and feed-through feature—are identical between the two parts.

For new designs or component refresh cycles, the 3-640606-5 is the recommended selection. For legacy system maintenance requiring exact tin-lead finish specification, the 640606-5 remains functionally equivalent where supply is available.

Frequently Asked Questions (FAQ)

Q: Can the 3-640606-5 directly replace the 640606-5 in existing assemblies?

A: Yes. The 3-640606-5 is electrically and mechanically equivalent to the 640606-5 across all functional parameters. Both connectors accommodate 5-position IDC termination with 22 AWG discrete or ribbon cable, maintain identical pitch and row configuration, and feature equivalent contact finish thickness. The primary difference is the contact finish material (tin versus tin-lead) and RoHS compliance status.

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

A: Both tin-lead and tin finishes provide equivalent electrical performance and contact resistance at the specified contact finish thickness of 80.0µin (2.03µm). The tin finish in the 3-640606-5 eliminates lead content, supporting RoHS compliance requirements. Selection between the two depends on regulatory requirements and legacy system specifications.

Q: Why is the 640606-5 classified as obsolete?

A: The 640606-5 is designated obsolete by TE Connectivity. The 3-640606-5 represents the current active product offering within the MTA-156 series for this connector configuration. For new procurement, the 3-640606-5 is the appropriate selection.

Q: Are there packaging differences between the 640606-5 and 3-640606-5?

A: The 640606-5 packaging information is not specified in available documentation. The 3-640606-5 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Does the RoHS compliance status affect electrical performance?

A: No. RoHS compliance status reflects regulatory and material composition requirements, not electrical performance. Both the 640606-5 and 3-640606-5 deliver identical electrical characteristics for IDC termination, contact resistance, and signal integrity.

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

A: Yes. Both the 640606-5 and 3-640606-5 support discrete or ribbon cable termination via IDC technology at 22 AWG wire gauge.

Q: What is the feed-through feature?

A: The feed-through feature indicates that the connector supports pass-through signal routing, allowing signals to be transmitted through the connector while maintaining connection points for additional circuit branches or monitoring.
