TE Connectivity 641127-2 Rectangular Connector: Equivalent & Substitute Parts

Part Overview

The TE Connectivity 641127-2 is a shrouded right-angle header connector from the MTA-100 series, designed for through-hole board-to-cable/wire applications. This connector features a 2-position configuration with 0.100" (2.54mm) pitch spacing and gold-plated mating contacts rated for 250VAC operation across an extended temperature range of -55°C to 105°C.

The 641127-2 carries an obsolete product status. Direct substitution with an active equivalent part is necessary to ensure continued availability, supply chain reliability, and access to current manufacturing batches with updated compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 641127-2 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following categories:

Electrical Parameters: Voltage rating (250VAC), contact material composition (copper alloy), contact finish specification (gold mating surface with 15.0µin thickness), and operating temperature range (-55°C to 105°C).

Mechanical Parameters: Connector configuration (2-position header), pitch spacing (0.100"/2.54mm), mounting orientation (through-hole right-angle), shrouding design (shrouded 1-wall), contact geometry (square shape), and termination method (solder).

Compliance Parameters: Material flammability rating (UL94 V-0), RoHS3 compliance, and moisture sensitivity level (MSL 1).

The substitute part 3-641127-2 satisfies all these criteria while offering the advantage of active product status and current manufacturing availability.

Parameter Comparison

Engineering Selection Recommendations

The 3-641127-2 is the direct functional equivalent of the 641127-2 and is suitable for all applications currently using the obsolete part number. Both connectors are manufactured by TE Connectivity within the MTA-100 series and maintain identical electrical, mechanical, and thermal specifications.

Product Status Advantage: The 3-641127-2 carries active product status, ensuring ongoing manufacturing support, consistent supply availability, and compliance with current industry standards. The 641127-2 is obsolete and subject to discontinuation without notice.

Compliance Certification: Both parts maintain ROHS3 compliance and UL94 V-0 flammability rating. The 3-641127-2 provides clarified REACH status (REACH Unaffected) compared to the vendor-undefined status of the obsolete part, offering improved regulatory documentation for supply chain and end-use applications.

Packaging Consideration: The 3-641127-2 is supplied in bulk packaging, whereas the 641127-2 packaging specification is not defined. Bulk packaging is standard for active MTA-100 series connectors and presents no compatibility issues for board-level assembly or field installation.

Frequently Asked Questions (FAQ)

Q: Are the 641127-2 and 3-641127-2 mechanically interchangeable?

A: Yes. Both connectors feature identical through-hole right-angle mounting geometry, 2-position configuration with 0.100" (2.54mm) pitch spacing, and shrouded 1-wall design. They mount identically on printed circuit boards and accept the same mating connectors and cable assemblies.

Q: Do these connectors have the same electrical ratings?

A: Yes. Both parts are rated for 250VAC operation, operate across the identical temperature range of -55°C to 105°C, and feature gold-plated mating contacts with copper alloy base material. Current rating varies by wire gauge for both parts.

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

A: The 641127-2 is obsolete, while the 3-641127-2 is active. The 3-641127-2 is supplied in bulk packaging and carries clarified REACH compliance status. All electrical and mechanical specifications are identical.

Q: Can I use the 3-641127-2 as a direct replacement in existing designs?

A: Yes. The 3-641127-2 is a direct substitute for the 641127-2 with no design modifications required. Existing PCB layouts, mating connector selections, and assembly procedures remain unchanged.

Q: Are there any compliance differences between these parts?

A: Both parts maintain ROHS3 compliance and UL94 V-0 flammability rating. The 3-641127-2 provides explicit REACH Unaffected status, whereas the 641127-2 lists REACH status as vendor undefined. This clarification in the active part simplifies regulatory documentation.

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

A: Both connectors carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These parts do not require special handling, storage, or baking procedures prior to assembly.

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

A: Yes. Both connectors operate across the full temperature range of -55°C to 105°C, supporting applications in industrial, automotive, and general-purpose environments within this thermal envelope.
