TE Connectivity 640600-4 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640600-4 is a 4-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 852 pieces in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector specification. 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 640600-4 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Contact type (Female Socket)
• Number of positions (4)
• Pitch spacing (0.156" / 3.96mm)
• Wire gauge compatibility (20 AWG)
• Cable termination method (IDC)

Mechanical Parameters:

• Connector type (Rectangular Receptacle)
• Mounting configuration (Free Hanging In-Line)
• Fastening mechanism (Locking Ramp)
• Number of rows (1)
• Feed-through feature

Environmental & Compliance Parameters:

• Moisture Sensitivity Level (MSL 1)
• Series designation (MTA-156)
• Product status (Active)

The substitute part 3-640600-4 maintains full equivalence across all electrical and mechanical parameters. Differences in contact finish composition (tin versus tin-lead) and RoHS compliance status do not affect functional interchangeability within the MTA-156 series specification.

Parameter Comparison

Engineering Selection Recommendations

640600-4 Selection Criteria: The original part number 640600-4 is appropriate for applications where tin-lead contact finish is specified or required by design documentation. This part maintains RoHS non-compliant status and is suitable for legacy systems or applications without RoHS restrictions. Current inventory of 852 pieces supports standard procurement volumes.

3-640600-4 Selection Criteria: The substitute part 3-640600-4 is functionally equivalent and provides ROHS3 compliance, making it suitable for applications subject to RoHS regulations or environmental compliance requirements. The tin contact finish (without lead) maintains the same contact finish thickness specification. Higher inventory availability (2849 pieces) in bulk packaging supports larger production runs and extended supply chain requirements.

Both parts are active products from TE Connectivity and maintain full electrical and mechanical compatibility within the MTA-156 series specification. Selection between these parts depends on compliance requirements and packaging needs rather than functional performance.

Frequently Asked Questions (FAQ)

Q: Are 640600-4 and 3-640600-4 electrically interchangeable?

A: Yes. Both connectors maintain identical electrical specifications including 4-position configuration, 0.156" pitch, 20 AWG wire gauge compatibility, and IDC termination method. Contact finish composition differences (tin-lead versus tin) do not affect electrical performance within the MTA-156 series specification.

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

A: The 640600-4 features tin-lead contact finish while the 3-640600-4 features tin contact finish. Both maintain 80.0µin (2.03µm) finish thickness. The primary distinction is RoHS compliance status: tin-lead is RoHS non-compliant, while tin is ROHS3 compliant.

Q: Can I use 3-640600-4 as a direct replacement for 640600-4?

A: Yes, for applications without RoHS restrictions. The 3-640600-4 is mechanically and electrically equivalent. For applications requiring RoHS non-compliant components, the original 640600-4 specification must be maintained.

Q: What does MSL 1 (Unlimited) mean for these connectors?

A: Moisture Sensitivity Level 1 indicates the connector has unlimited shelf life and requires no special moisture control during storage or handling. Both parts share this specification.

Q: Are there packaging differences between these parts?

A: Yes. The 640600-4 uses standard packaging while the 3-640600-4 is supplied in bulk packaging. Bulk packaging is typically used for high-volume production orders.

Q: Which part should I specify for new designs?

A: For new designs subject to RoHS regulations, specify 3-640600-4. For legacy systems or applications without RoHS requirements, either part is acceptable based on design documentation requirements.

Q: Do both parts support the same wire types?

A: Yes. Both connectors support discrete or ribbon cable with 20 AWG wire gauge using IDC termination method.
