Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 641209-4 are identified based on strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Contact type (Male Pin)
• Number of positions (4)
• Pitch spacing (0.156" / 3.96mm)
• Voltage rating (600VAC)
• Operating temperature range (-55°C ~ 105°C)
• Contact finish on mating surface (Gold)

Mechanical Compatibility Parameters:

• Connector type (Header)
• Mounting type (Through Hole)
• Termination method (Solder)
• Shrouding configuration (Shrouded - 1 Wall)
• Fastening type (Friction Lock)
• Insulation material (Thermoplastic, Glass Filled)
• Material flammability rating (UL94 V-0)

Regulatory Compliance Parameters:

• RoHS compliance status
• Moisture Sensitivity Level (MSL 1 - Unlimited)
• ECCN classification (EAR99)

The substitute part 3-641209-4 maintains full equivalence across all electrical and mechanical parameters. The primary distinction is packaging configuration (Bulk versus standard packaging) and minor contact finish specification on the post (Tin versus Tin-Lead).

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 641209-4 and 3-641209-4 are Active product status components manufactured by TE Connectivity AMP Connectors within the MTA-156 series. Selection between these parts is determined by packaging and compliance requirements rather than electrical or mechanical performance differences.

641209-4 is suitable for applications requiring standard packaging configurations with Tin-Lead contact finish on the post. This part maintains RoHS Compliant status and is appropriate for general purpose and industrial applications.

3-641209-4 is suitable for applications requiring bulk packaging with Tin contact finish on the post. This part maintains ROHS3 Compliant status, representing updated RoHS compliance documentation. The bulk packaging configuration provides cost efficiency for high-volume production requirements.

Both parts satisfy UL94 V-0 flammability requirements, operate across the -55°C to 105°C temperature range, and maintain 600VAC voltage rating specifications. The contact finish difference on the post (Tin-Lead versus Tin) does not affect mating surface performance, as both parts feature identical Gold plating on the mating contact surface at 30.0µin thickness.

Frequently Asked Questions (FAQ)

Q: Are the 641209-4 and 3-641209-4 interchangeable in circuit board applications?

A: Yes. Both parts are electrically and mechanically equivalent within the MTA-156 series. They feature identical contact configurations, pitch spacing (0.156"), mounting type (Through Hole), and termination method (Solder). The parts are directly interchangeable in board-to-cable/wire applications.

Q: What is the difference between the contact finish specifications on these parts?

A: The primary difference is the post contact finish: 641209-4 features Tin-Lead finish while 3-641209-4 features Tin finish.
