TE Connectivity 640468-3 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640468-3 is a 3-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, a closed-end design, and a locking ramp fastening mechanism. The part is currently active in production with 1114 pieces in stock. Substitute parts are identified to address specific application requirements, including RoHS compliance status and packaging format variations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 640468-3 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type (Receptacle)
• Number of positions (3)
• Pitch (0.100" / 2.54mm)
• Number of rows (1)
• Contact type (Female Socket)
• Cable termination method (IDC)
• Wire gauge (22 AWG)
• Wire type compatibility (Discrete or Ribbon Cable)
• Mounting type (Free Hanging, In-Line, Right Angle)
• Fastening type (Locking Ramp)
• Features (Closed End)
• Contact finish thickness (80.0µin / 2.03µm)
• Series designation (MTA-100)
• Moisture Sensitivity Level (1)

The substitute part 3-640468-3 maintains full electrical and mechanical compatibility with the main part across all critical parameters. The primary differences are contact finish composition (tin versus tin-lead) and packaging format (Cut Tape versus standard packaging), along with RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

640468-3 Selection Criteria: The 640468-3 is appropriate for applications where tin-lead contact finish is specified or required. This part is RoHS non-compliant and suitable for legacy systems or applications without RoHS restrictions. Standard packaging format is suitable for bulk procurement and automated assembly processes.

3-640468-3 Selection Criteria: The 3-640468-3 substitute is appropriate for applications requiring ROHS3 compliance. The tin contact finish provides equivalent electrical performance to the tin-lead variant while meeting modern regulatory requirements. Cut Tape packaging is suitable for high-volume automated pick-and-place assembly operations. Significantly higher inventory availability (46405 pieces) supports extended production runs and reduced lead times.

Both parts maintain identical electrical and mechanical specifications across all critical parameters. Selection between these parts is determined by regulatory compliance requirements and packaging format needs rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Are the 640468-3 and 3-640468-3 electrically interchangeable?

A: Yes. Both parts maintain identical electrical specifications including contact type, pitch, wire gauge, termination method, and contact finish thickness. The difference in contact finish material (tin-lead versus tin) does not affect electrical performance for standard IDC applications.

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

A: Both finishes provide equivalent electrical conductivity and contact resistance. The primary difference is regulatory compliance: tin-lead finish is RoHS non-compliant, while tin finish is ROHS3 compliant. Contact finish thickness is identical at 80.0µin (2.03µm) for both variants.

Q: Can I use the 3-640468-3 in place of the 640468-3?

A: Yes, provided your application does not specifically require tin-lead contact finish or non-compliant RoHS status. The 3-640468-3 is mechanically and electrically equivalent and offers the additional benefit of ROHS3 compliance.

Q: What does Cut Tape (CT) packaging mean?

A: Cut Tape packaging indicates the connector is supplied on a continuous tape that is cut to length, typically used for automated assembly equipment. Standard packaging may use alternative formats such as bulk or reel configurations.

Q: Are there any compatibility issues with ribbon cable versus discrete wire?

A: No. Both parts support IDC termination for discrete or ribbon cable at 22 AWG. The IDC termination method accommodates both cable types without modification.

Q: What is the significance of Moisture Sensitivity Level 1?

A: MSL 1 indicates unlimited shelf life without moisture control requirements. Both parts can be stored and handled under standard environmental conditions without special desiccant packaging or humidity controls.

Q: Does the locking ramp fastening type affect substitution?

A: No. Both parts use identical locking ramp fastening mechanisms. This ensures mechanical compatibility with mating connectors and assembly fixtures designed for the MTA-100 series.
