Mandatory Matching Parameters:

• Connector Type: Plug
• Number of Positions: 2
• Pitch: 0.156" (3.96mm)
• Number of Rows: 1
• Cable Termination: IDC
• Wire Gauge: 22 AWG
• Wire Type: Discrete or Ribbon Cable
• Contact Type: Male Pin
• Mounting Type: Free Hanging (In-Line), Right Angle
• Features: Feed Through
• Series: MTA-156

The substitute part 3-641524-2 maintains complete alignment with all mandatory parameters. The primary distinction between the main part and its substitute relates to product status, contact finish composition, and regulatory compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 3-641524-2

The 3-641524-2 is the direct substitute for the obsolete 641524-2. Both connectors share identical mechanical and electrical specifications across all critical parameters including connector type, position count, pitch, termination method, wire gauge, and mounting configuration.

Regulatory and Compliance Advantages:

The 3-641524-2 offers significant compliance improvements over the main part:

• RoHS3 Compliance: The substitute meets ROHS3 requirements, whereas the 641524-2 is RoHS non-compliant. This distinction is critical for applications subject to RoHS directives.
• REACH Status: The 3-641524-2 is REACH Unaffected, eliminating regulatory exposure associated with the REACH Affected status of the 641524-2.
• Contact Finish: The substitute employs pure tin contact finish instead of tin-lead, aligning with modern environmental and health standards while maintaining the same contact finish thickness of 80.0µin (2.03µm).

Product Status:

The 3-641524-2 maintains Active product status, ensuring ongoing availability, technical support, and supply chain continuity. The obsolete status of the 641524-2 presents supply constraints and limits access to manufacturer support.

Functional Equivalence:

Both parts operate identically within the MTA-156 series for 2-position, 22 AWG IDC applications. Mechanical fit, electrical performance, and cable compatibility are fully preserved in the substitution.

Frequently Asked Questions (FAQ)

Q: Are the 641524-2 and 3-641524-2 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications: 2 positions, 0.156" (3.96mm) pitch, 1 row configuration, and free hanging in-line/right angle mounting. Physical fit and mating with corresponding receptacles is identical.

Q: What is the functional difference between these two parts?

A: There is no functional difference in electrical or mechanical performance. Both connectors support 22 AWG discrete or ribbon cable termination via IDC, feature feed-through capability, and operate within the MTA-156 series. The primary differences are product status (obsolete vs. active), contact finish composition (tin-lead vs. tin), and regulatory compliance certifications.

Q: Why should I select the 3-641524-2 over the 641524-2?

A: The 3-641524-2 is the recommended selection because it is an active product with ROHS3 compliance and REACH Unaffected status. The 641524-2 is obsolete, creating supply availability risks. The tin contact finish of the substitute aligns with current environmental standards while maintaining equivalent electrical performance.

Q: Are there any compatibility concerns when substituting the 3-641524-2 for the 641524-2?

A: No compatibility concerns exist. The substitute maintains full mechanical and electrical equivalence. Existing mating connectors, cable assemblies, and system designs require no modification.

Q: What is the significance of the contact finish difference (tin-lead vs. tin)?

A: Both contact finishes provide equivalent electrical conductivity and contact resistance at the specified thickness of 80.0µin (2.03µm). The tin finish of the 3-641524-2 eliminates lead content, supporting RoHS3 compliance and modern environmental requirements.

Q: Does the MSL rating differ between these parts?

A: No. Both connectors carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints for storage or handling.

Q: Are the ECCN and HTSUS classifications identical?

A: Yes. Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4051) classifications, simplifying export documentation and customs procedures.

Q: What packaging options are available for the 3-641524-2?

A: The 3-641524-2 is supplied in Bulk packaging, whereas the 641524-2 packaging specification is not provided. Confirm packaging requirements with your procurement department.
