TE Connectivity 640442-9 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640442-9 is a 9-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 26 AWG discrete or ribbon cable. This connector features tin-lead contact finish, a closed-end design, and free-hanging or right-angle mounting configuration with locking ramp fastening. The part is currently active in production with 981 pieces in stock 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 updates, or inventory availability considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 640442-9 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Receptacle)
• Number of positions (9)
• Contact type (Female Socket)
• Pitch (0.100" / 2.54mm)
• Cable termination method (IDC)
• Wire gauge (26 AWG)
• Contact finish thickness (80.0µin / 2.03µm)

Mechanical Compatibility Parameters:

• Number of rows (1)
• Mounting type (Free Hanging / Right Angle)
• Fastening type (Locking Ramp)
• Wire type (Discrete or Ribbon Cable)
• Features (Closed End)

Environmental Parameters:

• Moisture Sensitivity Level (1 / Unlimited)
• Series designation (MTA-100)

The identified substitute part maintains all electrical and mechanical parameters while differing in contact finish composition and RoHS compliance status. Packaging configuration also differs between the main part and substitute.

Parameter Comparison

Engineering Selection Recommendations

640442-9 (Tin-Lead Contact Finish): This part is suitable for applications where RoHS non-compliance is acceptable or where legacy system compatibility with tin-lead plating is required. The tin-lead contact finish provides established performance characteristics in existing designs. Product status is active with standard packaging availability.

3-640442-9 (Tin Contact Finish): This substitute part is the appropriate selection for applications requiring ROHS3 compliance. The tin contact finish maintains the same contact finish thickness specification (80.0µin / 2.03µm) and all electrical and mechanical parameters as the main part. This part carries higher inventory availability (2126 pieces) and is supplied in bulk packaging. Product status is active.

Both parts are functionally equivalent for IDC termination applications with 26 AWG discrete or ribbon cable in 9-position MTA-100 series configurations. Selection between these parts is determined by regulatory compliance requirements and packaging specifications rather than electrical or mechanical performance differences.

Frequently Asked Questions (FAQ)

Q: Are the 640442-9 and 3-640442-9 connectors mechanically interchangeable?

A: Yes. Both connectors maintain identical mechanical specifications including 9-position configuration, 0.100" pitch, free-hanging or right-angle mounting, locking ramp fastening, and closed-end design. They are mechanically interchangeable in all applications.

Q: What is the difference between tin-lead and tin contact finishes in these connectors?

A: The 640442-9 features tin-lead contact finish while the 3-640442-9 features tin contact finish. Both maintain the same contact finish thickness of 80.0µin (2.03µm). The primary difference is RoHS compliance status: tin-lead is RoHS non-compliant, while tin is ROHS3 compliant.

Q: Can I use the 3-640442-9 as a direct replacement for the 640442-9 in existing designs?

A: The 3-640442-9 is electrically and mechanically equivalent to the 640442-9 for all IDC termination applications with 26 AWG discrete or ribbon cable. Selection depends on whether your application or regulatory environment requires ROHS3 compliance. If RoHS compliance is not a requirement, either part functions identically.

Q: What does IDC termination mean for these connectors?

A: IDC (Insulation Displacement Contact) termination allows direct connection of discrete wires or ribbon cables without stripping insulation. The connector contacts pierce through the wire insulation to establish electrical connection. Both the 640442-9 and 3-640442-9 support this termination method for 26 AWG wire.

Q: Are these connectors suitable for ribbon cable applications?

A: Yes. Both connectors support discrete or ribbon cable termination via IDC method. The 26 AWG wire gauge specification applies to both individual wires and ribbon cable conductors.

Q: What is the Moisture Sensitivity Level (MSL) rating for these connectors?

A: Both connectors carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

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

A: The 640442-9 is supplied in standard packaging, while the 3-640442-9 is supplied in bulk packaging. Bulk packaging typically accommodates higher-volume procurement requirements.
