TE Connectivity 640600-6 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640600-6 is a 6-position rectangular receptacle connector from the MTA-156 series, designed for IDC (Insulation Displacement Contact) termination with 20 AWG discrete or ribbon cable. This connector features tin-lead contact finish, free-hanging in-line mounting, and locking ramp fastening. The part is currently active in production with 1020 pieces available in inventory.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across connector specifications. Alternative part numbers may be necessary due to packaging requirements, compliance status changes, or inventory availability.

Number of positions (6)
Pitch specification (0.156" / 3.96mm)
Row configuration (1 row)
Cable termination method (IDC)
Wire gauge compatibility (20 AWG)
Contact finish thickness (80.0µin / 2.03µm)
Moisture sensitivity level (MSL 1)

Maintained Mechanical Parameters:

Mounting type (Free Hanging In-Line)
Fastening type (Locking Ramp)
Wire type compatibility (Discrete or Ribbon Cable)
Series designation (MTA-156)
Base product number (640600)

Differentiating Factors:

Contact finish composition (Tin-Lead vs. Tin)
Packaging format (standard vs. Bulk)
RoHS compliance status
Inventory availability

Engineering Selection Recommendations

Part 640600-6 Selection Criteria:

Applications where tin-lead contact finish is specified or required
Systems not subject to RoHS compliance requirements
Standard packaging requirements
Current inventory availability of 1020 pieces

Part 3-640600-6 Selection Criteria:

Applications requiring RoHS compliance
Systems designed for lead-free contact materials
Bulk packaging requirements
Higher inventory availability (1440 pieces)

Both parts maintain identical electrical and mechanical specifications within the MTA-156 series. The primary distinction is the contact finish composition and resulting RoHS compliance status. Selection between these parts is determined by regulatory requirements and packaging specifications rather than functional performance.

Frequently Asked Questions (FAQ)

Q: Are 640600-6 and 3-640600-6 electrically interchangeable?

A: Yes. Both connectors maintain identical electrical specifications including 6-position configuration, 0.156" pitch, 20 AWG wire gauge compatibility, and IDC termination method. The contact finish composition difference (tin-lead vs. tin) does not affect electrical performance within the specified parameters.

Q: What is the functional difference between tin-lead and tin contact finishes?

A: Contact finish composition affects material compliance and environmental performance characteristics. Tin-lead finish is used in non-RoHS applications, while tin finish is used in RoHS-compliant applications. Both finishes maintain the specified 80.0µin (2.03µm) thickness and electrical conductivity for this connector series.

Q: Can I use 3-640600-6 as a direct replacement for 640600-6?

A: Direct replacement is valid when the application permits RoHS-compliant components and bulk packaging. Verify that system specifications do not explicitly require tin-lead contact finish or standard packaging formats.

Q: Does packaging format affect connector performance?

A: Packaging format (standard vs. bulk) does not affect connector electrical or mechanical performance. Packaging selection is determined by procurement, inventory management, and supply chain requirements.

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

A: Yes. Both 640600-6 and 3-640600-6 support IDC termination for discrete or ribbon cable at 20 AWG wire gauge.

Q: What is the significance of MSL 1 rating for these connectors?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture control requirements. Both parts carry this rating and do not require special storage or handling conditions.
