Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1-640433-1 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector Type: Receptacle
• Contact Type: Female Socket
• Number of Positions: 11
• Pitch: 0.156" (3.96mm)
• Cable Termination: IDC
• Wire Gauge: 22 AWG
• Wire Type: Discrete or Ribbon Cable

Mechanical Compatibility Parameters:

• Series: MTA-156
• Number of Rows: 1
• Mounting Type: Free Hanging (In-Line)
• Features: Closed End
• Color: Red

Physical Parameters:

• Contact Finish Thickness: 80.0µin (2.03µm)

The substitute part 4-640433-1 maintains identical electrical and mechanical specifications while differing in contact finish material (tin versus tin-lead) and product status (active versus obsolete). This substitution is valid for applications where the contact finish material change does not impose regulatory or performance constraints.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 4-640433-1

The 4-640433-1 is the direct active equivalent of the obsolete 1-640433-1. Both parts share identical electrical and mechanical specifications within the MTA-156 series, including connector type, contact configuration, pitch, termination method, and wire gauge compatibility.

Compliance Considerations:

The 1-640433-1 carries RoHS non-compliant status with tin-lead contact finish. The 4-640433-1 is RoHS Compliant with tin contact finish. Selection between these parts depends on regulatory requirements applicable to the end application. For new designs or systems subject to RoHS directives, the 4-640433-1 is the appropriate selection. For legacy systems or applications with no RoHS constraints, either part functions identically from an electrical and mechanical standpoint.

Product Status:

The 1-640433-1 is classified as obsolete. The 4-640433-1 maintains active product status with documented inventory availability, ensuring long-term procurement viability and supply chain continuity.

Contact Finish Material:

The transition from tin-lead to tin contact finish in the 4-640433-1 does not alter the connector's functional performance within the specified 22 AWG IDC termination application. Both finishes provide equivalent contact resistance and durability characteristics at the specified contact finish thickness of 80.0µin (2.03µm).

Frequently Asked Questions (FAQ)

Q: Can the 4-640433-1 directly replace the 1-640433-1 in existing assemblies?

A: Yes. The 4-640433-1 maintains identical electrical and mechanical specifications. Both connectors are 11-position receptacles in the MTA-156 series with 0.156" pitch, IDC termination for 22 AWG wire, and closed-end design. Physical form factor and mating interface are equivalent.

Q: What is the difference between tin-lead and tin contact finish?

A: The 1-640433-1 uses tin-lead finish while the 4-640433-1 uses tin finish. Both are applied at 80.0µin (2.03µm) thickness. The primary distinction is regulatory compliance: tin-lead is RoHS non-compliant, while tin is RoHS Compliant. Functionally, both provide suitable contact resistance and durability for IDC applications.

Q: Why is the 1-640433-1 listed as obsolete?

A: The 1-640433-1 has been discontinued by TE Connectivity AMP Connectors. The 4-640433-1 serves as the active replacement, offering the same functionality with updated compliance status.

Q: Are there packaging differences between these parts?

A: The 1-640433-1 packaging is not specified in available documentation. The 4-640433-1 is supplied in bulk packaging. Packaging format does not affect connector performance or compatibility.

Q: What applications are these connectors suitable for?

A: These 11-position IDC receptacles are designed for discrete or ribbon cable termination at 22 AWG wire gauge. The free-hanging in-line mounting type and closed-end design support applications requiring reliable insulation displacement contact connections in the MTA-156 series standard.

Q: Is the 4-640433-1 available in inventory?

A: The 4-640433-1 is listed as active product status with 868 pieces documented as new original in stock.

Q: Can these connectors be used interchangeably with other MTA-156 series components?

A: These receptacles are compatible with MTA-156 series plug connectors and mating components that conform to the 0.156" (3.96mm) pitch standard and 11-position configuration. Compatibility is determined by matching pitch, position count, and connector type specifications.
