TE Connectivity AMP Connectors 641209-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 641209-3 is a rectangular connector header designed for through-hole mounting applications. This shrouded, single-row connector accommodates 3 positions at 0.156" (3.96mm) pitch and is classified as an active product. The connector features male pin contacts with gold-plated mating surfaces and tin-lead plated posts, suitable for general purpose and industrial applications requiring board-to-cable/wire connections with friction lock fastening.

Substitute parts are identified to address inventory availability, packaging preferences, or compliance requirement variations while maintaining functional and electrical equivalence.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector headers is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Contact type (Male Pin)
• Number of positions (3)
• Pitch - mating (0.156" / 3.96mm)
• Voltage rating (600VAC)
• Operating temperature range (-55°C ~ 105°C)

Mechanical Compatibility Parameters:

• Connector type (Header)
• Mounting type (Through Hole)
• Shrouding configuration (Shrouded - 1 Wall)
• Termination method (Solder)
• Fastening type (Friction Lock)

Material & Compliance Parameters:

• Contact material (Copper Alloy)
• Insulation material (Thermoplastic, Glass Filled)
• Flammability rating (UL94 V-0)
• RoHS compliance status

The substitute part 3-641209-3 maintains full equivalence across all critical parameters. Variations in packaging format (Bulk vs. standard) and contact finish on the post (Tin vs. Tin-Lead) do not affect functional substitutability for this connector category.

Parameter Comparison

Engineering Selection Recommendations

Both the 641209-3 and 3-641209-3 are active products manufactured by TE Connectivity AMP Connectors within the MTA-156 series. Selection between these parts is based on the following criteria:

Product Status & Compliance: Both parts maintain active product status and comply with applicable regulatory requirements. The 641209-3 carries RoHS Compliant certification, while the 3-641209-3 carries ROHS3 Compliant certification. Both are classified as RoHS-affected products with REACH status appropriately documented.

Packaging & Inventory Considerations: The 641209-3 is available in standard packaging with 759 pieces in stock. The 3-641209-3 is available in bulk packaging with 2522 pieces in stock. Selection should be based on procurement volume requirements and packaging format compatibility with assembly processes.

Contact Finish Variation: The primary technical difference is the post contact finish: 641209-3 features tin-lead plating, while 3-641209-3 features tin plating. Both finishes are compatible with solder termination processes and do not affect electrical performance or mechanical fit within the specified operating parameters.

Application Suitability: Both parts are designated for general purpose and industrial applications. The identical electrical ratings (600VAC), temperature range (-55°C ~ 105°C), and mechanical specifications ensure functional equivalence in board-to-cable/wire connection scenarios.

Frequently Asked Questions (FAQ)

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

A: Yes. The 3-641209-3 is a direct functional equivalent. Both parts share identical connector type, contact configuration, pitch, mounting method, and electrical ratings. The difference in post contact finish (tin-lead vs. tin) does not affect substitutability for solder termination applications.

Q: What is the significance of the packaging difference between these parts?

A: The 641209-3 is supplied in standard packaging, while the 3-641209-3 is supplied in bulk packaging. This distinction affects order quantities and handling procedures but does not impact the connector's electrical or mechanical performance. Selection should align with your assembly facility's packaging handling capabilities and procurement volume requirements.

Q: Are both parts RoHS compliant?

A: Yes. The 641209-3 is RoHS Compliant, and the 3-641209-3 is ROHS3 Compliant. Both meet current regulatory requirements for restricted substance limitations. The ROHS3 designation on the substitute part reflects the most current compliance standard.

Q: Does the contact finish difference affect solder joint reliability?

A: No. Both tin-lead and tin finishes are established post contact plating materials for solder termination. The 30.0µin (0.76µm) gold plating on mating contacts is identical in both parts, ensuring consistent contact resistance and mating performance.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors can be stored and handled under standard environmental conditions without special moisture control measures.

Q: Are these connectors suitable for high-temperature applications?

A: Yes. Both parts are rated for operating temperatures from -55°C to 105°C, making them suitable for industrial and general purpose applications within this thermal range. The UL94 V-0 flammability rating provides additional assurance for safety-critical applications.

Q: What is the current rating for these connectors?

A: The current rating varies by wire gauge. Consult the wire gauge specifications and associated current tables provided by TE Connectivity for your specific application requirements.
