TE Connectivity 641218-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 641218-2 is a 2-position rectangular receptacle connector from the MTA-156 series, designed for IDC (Insulation Displacement Contact) termination with 20 AWG wire. This connector features gold-plated contacts, a closed-end design, and free-hanging in-line mounting configuration. The part is classified as obsolete, making identification of active equivalent components essential for ongoing procurement and system maintenance. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct interchangeability without circuit redesign or system reconfiguration.

Engineering Selection Recommendations

The part 3-641218-2 is the direct equivalent substitute for the obsolete 641218-2. Selection of the substitute part is based on the following engineering criteria:

Product Status Consideration: The main part 641218-2 carries obsolete status, indicating discontinued manufacturing and limited availability. The substitute 3-641218-2 maintains active product status with confirmed inventory of 1112 pieces, ensuring long-term procurement viability.

Compliance Alignment: Both parts maintain RoHS compliance and identical MSL ratings (1 - Unlimited), confirming suitability for standard industrial and commercial applications without moisture sensitivity constraints. ECCN and HTSUS classifications are identical, supporting equivalent regulatory and trade compliance.

Electrical and Mechanical Equivalence: Complete parameter matching across connector type, position count, pitch, contact configuration, wire gauge, termination method, and contact finish specifications confirms direct interchangeability. No circuit redesign, PCB modification, or connector housing changes are required.

Packaging Availability: The substitute part is available in bulk packaging, supporting both prototype and production-volume procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the 3-641218-2 be used as a direct replacement for the 641218-2 without any modifications?
