TE Connectivity 640433-9 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640433-9 is a 9-position rectangular receptacle connector from the MTA-156 series, designed for IDC (Insulation Displacement Contact) termination with 22 AWG discrete or ribbon cable. This connector features tin-lead contact finish and is classified as a free-hanging, in-line mounting component with closed-end design. The part is currently active in production with 897 pieces available in new original inventory stock.

Identification of equivalent and substitute parts is necessary to address supply chain requirements, compliance specifications, and packaging preferences while maintaining electrical and mechanical compatibility within the MTA-156 connector family.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the MTA-156 rectangular connector family is determined by strict equivalence across the following parameters:

• Connector Type & Position Count: Both main and substitute parts are 9-position receptacles
• Pitch & Row Configuration: Both maintain 0.156" (3.96mm) pitch with single-row layout
• Cable Termination & Wire Gauge: Both support IDC termination for 22 AWG discrete or ribbon cable
• Contact Configuration: Both feature female socket contacts with closed-end design
• Mounting Orientation: Both are free-hanging, in-line mounted components
• Contact Finish Thickness: Both maintain 80.0µin (2.03µm) finish thickness

The substitute part 3-640433-9 differs from the main part 640433-9 in contact finish composition (tin versus tin-lead) and RoHS compliance status. These differences do not affect electrical or mechanical compatibility within the MTA-156 series.

Parameter Comparison

Engineering Selection Recommendations

Part 640433-9 is suitable for applications where tin-lead contact finish is specified or required by design documentation. This part maintains active production status and is available in current inventory.

Part 3-640433-9 is the appropriate selection for applications requiring RoHS compliance. This substitute maintains identical electrical and mechanical specifications while offering superior regulatory compliance status. The substitute part is available in bulk packaging and maintains higher inventory levels (1518 pieces versus 897 pieces).

Both parts are manufactured by TE Connectivity AMP Connectors and belong to the active product portfolio. Selection between these parts should be based on regulatory requirements (RoHS compliance) and packaging needs rather than electrical or mechanical performance, as both parts are fully equivalent within the MTA-156 series.

Frequently Asked Questions (FAQ)

Q: Are parts 640433-9 and 3-640433-9 electrically interchangeable?

A: Yes. Both parts are 9-position receptacles with identical pitch (0.156"), contact configuration (female socket), termination method (IDC), and wire gauge (22 AWG). They are fully electrically compatible within the MTA-156 series.

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

A: The main part (640433-9) features tin-lead contact finish, while the substitute (3-640433-9) features tin contact finish. Both maintain the same finish thickness (80.0µin / 2.03µm). The contact finish material does not affect mechanical compatibility or IDC termination performance.

Q: Why does part 3-640433-9 have RoHS compliance while 640433-9 does not?

A: The tin contact finish in part 3-640433-9 eliminates lead content, making it RoHS compliant. The tin-lead finish in part 640433-9 contains lead and is therefore RoHS non-compliant. Both parts are electrically and mechanically equivalent.

Q: Can I use part 3-640433-9 as a direct replacement for 640433-9 in existing designs?

A: Yes, part 3-640433-9 is a direct substitute for 640433-9. Both parts maintain identical position count, pitch, mounting type, and IDC termination specifications. The substitute part is suitable for new designs and retrofit applications.

Q: What does "Closed End" mean for these connectors?

A: Closed end indicates that the connector housing has a sealed design at the rear, preventing access to the contact area from the back side. This design is standard for IDC receptacles in the MTA-156 series.

Q: Are both parts available in the same packaging options?

A: Part 640433-9 packaging is not specified in available documentation. Part 3-640433-9 is available in bulk packaging. Packaging availability should be confirmed with the supplier for specific procurement requirements.

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

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors can be stored and handled without special moisture control measures.
