Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector headers within this product category is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Pitch - Mating: 0.156" (3.96mm)
• Number of Positions: 7
• Voltage Rating: 600VAC
• Contact Type: Male Pin
• Contact Finish - Mating: Gold

Mechanical Compatibility Parameters:

• Connector Type: Header
• Mounting Type: Through Hole
• Shrouding: Shrouded - 1 Wall
• Series: MTA-156
• Contact Shape: Circular
• Overall Contact Length: 0.650" (16.51mm)

Environmental & Compliance Parameters:

• Operating Temperature: -55°C ~ 105°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: RoHS Compliant

The substitute part 3-641209-7 maintains full equivalence across all critical electrical and mechanical parameters. The primary distinction is packaging format (Bulk versus standard packaging) and minor variation in post contact finish specification (Tin versus Tin-Lead).

Parameter Comparison

Engineering Selection Recommendations

Both the 641209-7 and 3-641209-7 are Active product status components manufactured by TE Connectivity and maintain full compliance with RoHS directives and UL94 V-0 flammability standards. The parts are functionally and mechanically interchangeable for all board-to-cable/wire interconnection applications within the specified operating temperature range of -55°C to 105°C and voltage rating of 600VAC.

The substitute part 3-641209-7 differs only in packaging format (Bulk) and post contact finish specification (Tin versus Tin-Lead). Both contact finish specifications are compatible with standard solder termination processes and do not affect electrical performance or mechanical fit within the MTA-156 series connector ecosystem.

Selection between these parts should be based on packaging requirements and inventory availability rather than electrical or mechanical performance considerations.

Frequently Asked Questions (FAQ)

Q: Are the 641209-7 and 3-641209-7 electrically interchangeable?

A: Yes. Both parts maintain identical electrical specifications including 600VAC voltage rating, -55°C to 105°C operating temperature range, and gold-plated mating contacts with 30.0µin (0.76µm) finish thickness.

Q: What is the difference between the two part numbers?

A: The primary differences are packaging format (standard versus Bulk) and post contact finish specification (Tin-Lead versus Tin). Both finishes are compatible with solder termination and do not affect connector performance or mechanical compatibility.

Q: Can I substitute 3-641209-7 for 641209-7 in existing designs?

A: Yes. The substitute part maintains full mechanical and electrical compatibility. The connector type, pitch, number of positions, mounting method, shrouding configuration, and all critical performance parameters are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both 641209-7 and 3-641209-7 are RoHS Compliant and carry UL94 V-0 material flammability ratings.

Q: What is the mating pitch for these connectors?

A: The mating pitch is 0.156" (3.96mm), which is the standard spacing for the MTA-156 series rectangular connector headers.

Q: What mounting method is used for these connectors?

A: Both parts utilize through-hole mounting with solder termination and friction lock fastening for board-to-cable/wire applications.

Q: Are there any temperature or voltage limitations I should consider?

A: Both parts operate within -55°C to 105°C and are rated for 600VAC. These specifications apply to all general purpose and industrial applications within the stated environmental parameters.

Q: What is the contact material composition?

A: Both parts feature copper alloy contacts with gold plating on the mating surface (30.0µin thickness) and tin or tin-lead plating on the post surface for solder termination.
