TE Connectivity 641209-6 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 641209-6 is a shrouded vertical connector header designed for through-hole mounting in board-to-cable/wire applications. This rectangular connector features 6 positions with 0.156" (3.96mm) pitch spacing and is part of the MTA-156 series. The connector is actively manufactured and widely used in general purpose and industrial applications requiring reliable solder termination with friction lock fastening. Substitute parts are identified when inventory constraints, packaging requirements, or specific application needs necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 641209-6 are identified based on strict electrical and mechanical parameter matching within the MTA-156 connector series. The substitution criteria are defined by the following parameters:

Critical Matching Parameters:

• Connector series designation (MTA-156)
• Number of positions (6)
• Pitch spacing (0.156" / 3.96mm)
• Contact type (Male Pin)
• Mounting method (Through Hole)
• Shrouding configuration (Shrouded - 1 Wall)
• Termination method (Solder)
• Fastening mechanism (Friction Lock)
• Operating temperature range (-55°C ~ 105°C)
• Voltage rating (600VAC)
• Flammability rating (UL94 V-0)

The substitute part 3-641209-6 maintains identical electrical and mechanical specifications to the main part number 641209-6. Both parts are manufactured by TE Connectivity AMP Connectors and are actively produced. The primary distinction between these parts is packaging configuration and minor contact finish specifications on the post termination.

Parameter Comparison

Engineering Selection Recommendations

Both the main part number 641209-6 and the substitute part number 3-641209-6 are actively manufactured by TE Connectivity AMP Connectors and maintain full ROHS3 compliance. Both parts carry identical electrical ratings, mechanical specifications, and environmental certifications including UL94 V-0 flammability rating.

The substitute part 3-641209-6 differs from the main part only in packaging configuration (bulk versus standard) and post contact finish specification (tin versus tin-lead). The post contact finish difference does not affect electrical or mechanical compatibility, as both finishes provide equivalent solder joint reliability and conductivity for through-hole termination applications.

Selection between these parts should be based on:

1. Packaging Requirements: The main part 641209-6 is supplied in standard packaging, while the substitute 3-641209-6 is supplied in bulk packaging. Bulk packaging is appropriate for high-volume manufacturing operations.

2. Inventory Availability: The substitute part 3-641209-6 currently has 874 pieces in stock compared to 738 pieces for the main part 641209-6.

3. Application Compliance: Both parts satisfy general purpose and industrial applications within the specified operating temperature range of -55°C to 105°C and voltage rating of 600VAC.

Both parts are suitable for direct substitution in applications where the MTA-156 series 6-position header connector is specified.

Frequently Asked Questions (FAQ)

Q: Can part number 3-641209-6 be used as a direct replacement for 641209-6?
