TE Connectivity 640602-5 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640602-5 is a 5-position rectangular receptacle connector from the MTA-156 series, designed for IDC (Insulation Displacement Contact) termination with 24 AWG discrete or ribbon cable. This connector features tin-lead contact finish and free-hanging in-line mounting with locking ramp fastening.

The 640602-5 is classified as obsolete. Locating equivalent substitute parts is necessary to support ongoing maintenance, repair, and production requirements for systems utilizing this connector configuration.

Substitute Part Grouping Explanation

Substitution eligibility for the 640602-5 is determined by strict equivalence across the following critical parameters:

Connector Type & Contact Configuration: Receptacle with female socket contacts
Position Count & Pitch: 5 positions at 0.156" (3.96mm) pitch
Row Configuration: Single row layout
Mounting & Fastening: Free hanging in-line with locking ramp fastening
Termination Method: IDC cable termination
Wire Compatibility: 24 AWG discrete or ribbon cable support
Mechanical Features: Feed through capability
Contact Finish Thickness: 80.0µin (2.03µm)
Physical Appearance: White color housing

The substitute part 3-640602-5 maintains full equivalence across all mechanical and electrical parameters. The primary distinction is the contact finish material and product status classification.

Engineering Selection Recommendations

The 3-640602-5 serves as the direct substitute for the obsolete 640602-5. Both connectors maintain identical mechanical and electrical specifications across all critical parameters including position count, pitch, mounting configuration, termination method, and wire gauge compatibility.

The 3-640602-5 is classified as an active product with current manufacturing support and availability. This part is RoHS compliant, whereas the original 640602-5 is RoHS non-compliant. The contact finish differs between the two parts: the original uses tin-lead while the substitute uses tin. Both finishes maintain the same thickness specification of 80.0µin (2.03µm).

For applications requiring RoHS compliance or where long-term component availability is a requirement, the 3-640602-5 is the appropriate selection. For legacy system repairs where original tin-lead contact finish is mandated by specification, compatibility assessment with the tin finish of the substitute part is necessary.

Frequently Asked Questions (FAQ)

Q: Are the 640602-5 and 3-640602-5 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 5-position configuration, 0.156" pitch, free-hanging in-line mounting, locking ramp fastening, and feed-through capability. Physical dimensions and mating interfaces are equivalent.

Q: Can the 3-640602-5 terminate the same cable types as the 640602-5?

A: Yes. Both connectors support IDC termination for 24 AWG discrete or ribbon cable. The termination method, wire gauge compatibility, and cable interface are identical.

Q: What is the difference in contact finish between these two parts?

A: The 640602-5 features tin-lead contact finish while the 3-640602-5 features tin contact finish. Both maintain 80.0µin (2.03µm) thickness. The tin finish of the substitute part is suitable for standard electronic applications. Applications with specific tin-lead requirements should be evaluated for compatibility with the tin finish alternative.

Q: Why is the 640602-5 classified as obsolete?

A: The 640602-5 is no longer in active production. The 3-640602-5 represents the current active equivalent from TE Connectivity AMP Connectors.

Q: Is the 3-640602-5 RoHS compliant?

A: Yes. The 3-640602-5 is RoHS compliant. The original 640602-5 is RoHS non-compliant. For applications subject to RoHS regulations, the 3-640602-5 is the appropriate selection.

Q: Are there packaging differences between these connectors?

A: The 640602-5 packaging specification is not provided. The 3-640602-5 is supplied in bulk packaging. Packaging configuration should be confirmed based on application requirements and procurement specifications.
