Substitute Part Grouping Explanation

Substitution between the main part 644465-7 and the identified substitute 3-644465-7 is valid based on the following criteria:

Matching Critical Parameters:

• Connector type, position count, and pitch remain identical
• Series designation (MTA-156) is preserved
• IDC cable termination method is unchanged
• Wire gauge (18 AWG) is identical
• Contact type (female socket) is identical
• Mounting configuration (free hanging, in-line) is identical
• Fastening mechanism (locking ramp) is identical
• Contact finish thickness (80.0µin / 2.03µm) is identical
• Color (orange) is identical
• Moisture sensitivity level (MSL 1) is identical

Differentiating Parameters:

• Contact finish: 644465-7 uses tin-lead; 3-644465-7 uses tin
• RoHS compliance: 644465-7 is non-compliant; 3-644465-7 is compliant
• Packaging: 644465-7 is unspecified; 3-644465-7 is bulk
• REACH status: 644465-7 is affected; 3-644465-7 is vendor undefined

The substitute part 3-644465-7 provides functional and mechanical equivalence with improved regulatory compliance for applications requiring RoHS-compliant components.

Parameter Comparison

Engineering Selection Recommendations

For RoHS-Compliant Applications: Select 3-644465-7. This substitute part maintains all functional and mechanical specifications of the main part while providing RoHS compliance. The tin contact finish replaces the tin-lead finish, eliminating lead content and meeting regulatory requirements for restricted substance directives.

For Legacy or Non-Regulated Applications: Either part is suitable. The 644465-7 remains available with higher inventory status for immediate deployment in applications without RoHS requirements.

For Inventory Optimization: The substitute part 3-644465-7 offers greater stock availability (1543 pieces versus 868 pieces), supporting supply chain continuity and lead-time reduction.

For Regulatory Documentation: Applications subject to REACH or RoHS compliance mandates require 3-644465-7. The main part 644465-7 carries REACH-affected status and RoHS non-compliance designation, making it unsuitable for regulated markets.

Frequently Asked Questions (FAQ)

Q: Can 3-644465-7 be used as a direct replacement for 644465-7 in existing designs?

A: Yes. The substitute part 3-644465-7 is mechanically and functionally equivalent. All critical parameters including connector type, position count, pitch, IDC termination, wire gauge, mounting configuration, and fastening mechanism are identical. The primary difference is the contact finish material (tin versus tin-lead) and RoHS compliance status.

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

A: Both finishes provide equivalent electrical conductivity and contact performance at the specified contact finish thickness (80.0µin / 2.03µm). The tin finish in 3-644465-7 eliminates lead content, meeting RoHS compliance requirements. Selection between them depends on regulatory requirements and application constraints, not electrical performance.

Q: Are there mechanical compatibility issues when substituting between these parts?

A: No. Both parts share identical mechanical specifications: 7-position configuration, 0.156" pitch, free-hanging in-line mounting, locking ramp fastening, and polarizing key features. They are mechanically interchangeable within the same connector system.

Q: Does the contact finish thickness differ between the two parts?

A: No. Both parts specify 80.0µin (2.03µm) contact finish thickness, ensuring equivalent contact resistance and durability characteristics.

Q: Which part should be selected for new product designs?

A: For new designs, 3-644465-7 is the appropriate selection. It provides RoHS compliance, superior inventory availability, and maintains full functional equivalence with the main part. This ensures regulatory alignment and supply chain resilience.

Q: Is the IDC termination method identical for both parts?

A: Yes. Both parts use IDC (Insulation Displacement Contact) termination for 18 AWG discrete or ribbon cable. The termination process, tooling, and cable compatibility are identical.

Q: What is the significance of the base product number 644465?

A: The base product number 644465 identifies the core connector design family. Both the main part (644465-7) and substitute (3-644465-7) share this base number, indicating they are variants within the same product line with identical mechanical and electrical architecture.

Q: Are there packaging differences that affect component handling?

A: The main part 644465-7 has unspecified packaging, while 3-644465-7 is supplied in bulk packaging. Bulk packaging typically offers cost advantages and is standard for high-volume applications. Packaging selection should align with assembly process requirements and inventory management practices.
