Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 640434-6 is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Rectangular receptacle with 6 positions in single-row arrangement
• Pitch Specification: 0.156" (3.96mm) contact spacing
• Termination Technology: IDC cable termination compatibility
• Wire Gauge Compatibility: 24 AWG discrete or ribbon cable
• Contact Geometry: Female socket contacts with closed-end housing
• Series Designation: MTA-156 series membership
• Mounting Profile: Free hanging in-line orientation

The substitute part 3-640434-6 satisfies all these parameters identically, with the primary distinction being contact finish composition and product status classification.

Engineering Selection Recommendations

Primary Substitute: 3-640434-6

The 3-640434-6 is the direct functional equivalent of the 640434-6 and is the recommended selection for new designs and component replacement applications.

Justification Based on Provided Parameters:

1. Functional Compatibility: All electrical and mechanical parameters are identical, including connector geometry, pitch, termination method, wire gauge, and contact configuration.

2. Product Status: The 640434-6 is classified as obsolete, whereas 3-640434-6 maintains active product status with current manufacturing support and availability (1066 pcs in stock versus 722 pcs for the obsolete part).

3. Regulatory Compliance: The 3-640434-6 is ROHS3 compliant, whereas the 640434-6 is RoHS non-compliant. This distinction is material for applications subject to RoHS directives and environmental regulations.

4. Contact Finish Specification: The 3-640434-6 uses tin contact finish versus tin-lead in the original part. Both maintain identical contact finish thickness (80.0µin / 2.03µm) and are functionally equivalent for IDC termination applications.

5. Moisture Sensitivity: Both parts share MSL 1 (Unlimited) classification, indicating no moisture sensitivity constraints during storage or handling.

6. Export Classification: Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.8000) designations.

Frequently Asked Questions (FAQ)

Q: Can the 3-640434-6 be used as a direct replacement for the 640434-6 in existing assemblies?

A: Yes. The 3-640434-6 is functionally equivalent across all electrical and mechanical parameters. The connector geometry, pitch, contact configuration, termination method, and wire gauge compatibility are identical. The primary differences are product status (active versus obsolete) and regulatory compliance (ROHS3 compliant versus non-compliant).

Q: What is the difference between tin-lead and tin contact finishes in this application?

A: Both contact finishes are applied at identical thickness (80.0µin / 2.03µm) and provide equivalent performance for IDC termination. The tin finish in the 3-640434-6 reflects current manufacturing standards and RoHS3 compliance requirements.

Q: Are there any compatibility issues with ribbon cable or discrete wire termination?

A: No. Both the 640434-6 and 3-640434-6 support identical cable termination specifications: discrete or ribbon cable at 24 AWG wire gauge using IDC termination technology.

Q: Does the obsolete status of the 640434-6 affect its electrical performance?

A: No. Obsolete classification indicates end-of-life manufacturing status and supply availability, not electrical or mechanical performance degradation. However, the active status of the 3-640434-6 ensures continued availability and manufacturing support.

Q: What is the significance of the RoHS compliance difference?

A: The 3-640434-6 is ROHS3 compliant, meeting current environmental and hazardous substance restrictions. The 640434-6 is RoHS non-compliant. For applications subject to RoHS directives or customer requirements, the 3-640434-6 is the appropriate selection.

Q: Are the moisture sensitivity levels identical?

A: Yes. Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage, handling, or assembly processes.

Q: Can these connectors be used interchangeably in new product designs?

A: Yes. The 3-640434-6 is the recommended selection for new designs due to its active product status, ROHS3 compliance, and current market availability. All functional parameters remain equivalent to the 640434-6.
