TE Connectivity 641435-9 Rectangular Connector: Equivalent & Substitute Parts

Part Overview

The TE Connectivity 641435-9 is a 9-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 a free-hanging, in-line or right-angle mounted component with closed-end design. The part is currently active in production with 1,013 units in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across connector specifications. Alternative part numbers may be necessary due to inventory availability, packaging requirements, or compliance status changes.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 641435-9 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Plug)
• Number of positions (9)
• Contact type (Male Pin)
• Pitch (0.156" / 3.96mm)
• Cable termination method (IDC)
• Wire gauge (18 AWG)
• Wire type compatibility (Discrete or Ribbon Cable)

Mechanical Compatibility Parameters:

• Number of rows (1)
• Mounting type (Free Hanging, In-Line, Right Angle)
• Features (Closed End)
• Series designation (MTA-156)
• Contact finish thickness (80.0µin / 2.03µm)

Environmental & Compliance Parameters:

• Moisture Sensitivity Level (MSL 1)

The substitute part 3-641435-9 maintains full equivalence across all electrical and mechanical parameters. Variations in contact finish material (tin versus tin-lead), packaging format, RoHS compliance status, and REACH classification do not affect functional interchangeability in applications where the core electrical and mechanical specifications are the controlling factors.

Parameter Comparison

Engineering Selection Recommendations

Both the 641435-9 and 3-641435-9 are active production parts from TE Connectivity AMP Connectors and maintain full functional equivalence for applications requiring 9-position IDC rectangular connectors with 18 AWG wire termination.

Selection Criteria Based on Compliance Requirements:

The primary distinction between these parts is regulatory compliance status. The 641435-9 carries tin-lead contact finish and is RoHS non-compliant, suitable for applications without RoHS restrictions. The 3-641435-9 features tin contact finish and is ROHS3 compliant, meeting current European Union Restriction of Hazardous Substances directives.

Applications subject to RoHS3 compliance mandates or customer specifications requiring lead-free components should specify the 3-641435-9. Applications without such restrictions may utilize either part based on inventory availability and packaging requirements.

Packaging Considerations:

The 641435-9 is supplied in standard packaging, while the 3-641435-9 is supplied in bulk packaging. Procurement decisions should account for assembly line integration requirements and component handling procedures.

Both parts maintain identical electrical performance, mechanical fit, and environmental ratings (MSL 1). Contact finish material differences (tin-lead versus tin) do not affect connector mating, unmating, or signal integrity characteristics within the specified electrical parameters.

Frequently Asked Questions (FAQ)

Q: Are the 641435-9 and 3-641435-9 mechanically interchangeable?

A: Yes. Both connectors maintain identical pitch (0.156"), position count (9), row configuration (1), mounting type (free hanging, in-line, right angle), and closed-end design. Physical mating and mechanical fit are equivalent.

Q: What is the functional difference between tin-lead and tin contact finishes in these connectors?

A: Both contact finishes provide equivalent electrical conductivity and contact resistance performance at the specified contact finish thickness of 80.0µin (2.03µm). The distinction is regulatory: tin-lead finish is associated with RoHS non-compliance, while tin finish supports ROHS3 compliance.

Q: Can I substitute the 641435-9 with the 3-641435-9 in an existing design?

A: Substitution is permissible when the application does not impose RoHS compliance restrictions. Both parts are electrically and mechanically equivalent. Verify that your application or customer specifications do not mandate lead-free components before selecting the tin-lead version.

Q: Does packaging format affect connector performance?

A: No. Standard and bulk packaging formats do not affect electrical or mechanical performance. Packaging selection is determined by assembly process requirements, component handling procedures, and inventory management practices.

Q: Are both parts suitable for IDC termination with 18 AWG ribbon cable?

A: Yes. Both the 641435-9 and 3-641435-9 are designed for IDC termination with 18 AWG discrete or ribbon cable. Termination compatibility is identical.

Q: What is the significance of MSL 1 (Unlimited) rating for these connectors?

A: MSL 1 indicates unlimited shelf life without moisture sensitivity concerns. These connectors do not require special moisture-controlled storage or handling procedures prior to assembly.

Q: Are there any electrical performance differences between these substitute parts?

A: No. Both connectors maintain identical electrical specifications including contact type (male pin), pitch (0.156"), and contact finish thickness (80.0µin). Signal integrity and electrical performance are equivalent.
