TE Connectivity 1-641435-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-641435-2 is a 12-position rectangular plug connector from the MTA-156 series, designed for IDC (Insulation Displacement Contact) termination with 18 AWG discrete or ribbon cable. This connector features tin-lead contact finish and is classified as obsolete product status. Due to its obsolete designation, identification of equivalent substitute parts is necessary to support ongoing maintenance, repair, and production requirements where this connector type remains functionally required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1-641435-2 is determined by strict equivalence across the following critical parameters:

• Series Compatibility: Both parts must belong to the MTA-156 series to ensure mechanical and electrical interchangeability
• Position Count: 12-position configuration must be maintained
• Pitch Specification: 0.156" (3.96mm) pitch is required for proper mating with existing receptacles
• Contact Type: Male pin configuration must be preserved
• Cable Termination Method: IDC termination capability is mandatory
• Wire Gauge: 18 AWG compatibility is required
• Mounting Configuration: Free Hanging (In-Line) and Right Angle mounting options must be supported
• Contact Finish Thickness: 80.0µin (2.03µm) specification must be matched

The substitute part 4-641435-2 meets all these critical parameters and is therefore classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 4-641435-2 serves as the direct functional equivalent to the obsolete 1-641435-2. Both connectors share identical mechanical and electrical specifications across all critical parameters including series designation, position count, pitch, contact configuration, termination method, and wire gauge compatibility.

The primary distinction between these parts is the contact finish specification. The main part 1-641435-2 features tin-lead contact finish, while the substitute 4-641435-2 features tin contact finish. Both finishes maintain the same thickness specification of 80.0µin (2.03µm), ensuring equivalent electrical performance and contact resistance characteristics.

An additional distinction is product status and regulatory compliance. The 1-641435-2 is designated as obsolete and RoHS non-compliant, whereas the 4-641435-2 is active product status and RoHS compliant. For applications requiring RoHS compliance or long-term supply chain continuity, the 4-641435-2 is the appropriate selection. Both parts are classified under ECCN EAR99 and share the same HTSUS code 8536.69.8000.

Frequently Asked Questions (FAQ)

Q: Can the 4-641435-2 be used as a direct replacement for the 1-641435-2 in existing assemblies?

A: Yes. The 4-641435-2 is mechanically and electrically equivalent to the 1-641435-2 across all critical parameters. Both connectors are 12-position MTA-156 series plugs with identical pitch, contact configuration, IDC termination capability, and 18 AWG wire gauge compatibility. The connectors are interchangeable in applications where the existing mating receptacles are designed for MTA-156 series plugs.

Q: What is the difference between the tin-lead finish on the 1-641435-2 and the tin finish on the 4-641435-2?

A: Both contact finishes maintain the same thickness specification of 80.0µin (2.03µm). The primary difference is the alloy composition. The 1-641435-2 uses tin-lead, while the 4-641435-2 uses tin. Both finishes provide equivalent electrical performance and contact resistance. The tin finish on the 4-641435-2 aligns with RoHS compliance requirements.

Q: Why is the 1-641435-2 listed as obsolete?

A: The 1-641435-2 is designated as obsolete product status by TE Connectivity. The 4-641435-2 is the active equivalent part that replaces it in the product line. For new designs and ongoing production, the 4-641435-2 should be specified.

Q: Are there packaging differences between these two parts?

A: The 1-641435-2 packaging is not specified in the available data. The 4-641435-2 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: What is the Moisture Sensitivity Level (MSL) for these connectors?

A: Both the 1-641435-2 and 4-641435-2 are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are both parts subject to REACH regulations?

A: The 1-641435-2 is listed as REACH Affected. The 4-641435-2 is listed as Vendor Undefined for REACH status. Consult with your supplier or TE Connectivity for specific REACH compliance documentation applicable to your application and region.
