Substitute Part Grouping Explanation

Substitution between the TE Connectivity 640443-7 and equivalent parts is determined by strict alignment of electrical and mechanical parameters. The primary substitute identified is the TE Connectivity 3-640443-7, which maintains identical specifications across all critical parameters:

Critical Parameters (Must Match Exactly):

• Connector type: Receptacle
• Number of positions: 7
• Pitch: 0.100" (2.54mm)
• Contact type: Female Socket
• Cable termination: IDC
• Wire gauge: 28 AWG
• Number of rows: 1
• Mounting type: Free Hanging (In-Line), Right Angle
• Fastening type: Locking Ramp
• Closed-end configuration

Important Parameters (Allowable Variation):

• Contact finish: Tin-Lead (640443-7) versus Tin (3-640443-7)
• Contact finish thickness: Both 80.0µin (2.03µm)
• RoHS compliance status: Non-compliant (640443-7) versus Compliant (3-640443-7)
• Packaging: Standard versus Bulk

The 3-640443-7 serves as a direct functional equivalent with the primary distinction being the contact finish composition and resulting RoHS compliance status. Both parts are manufactured by TE Connectivity within the MTA-100 series and share identical mechanical and electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

For RoHS Non-Compliant Applications: The 640443-7 with tin-lead contact finish is suitable for applications where RoHS compliance is not required. This part maintains active production status and has adequate inventory availability (1,046 units in stock).

For RoHS Compliant Applications: The 3-640443-7 with tin contact finish is the appropriate selection for designs requiring RoHS compliance. This substitute maintains all critical electrical and mechanical parameters while meeting environmental regulatory requirements. The 3-640443-7 offers superior inventory availability with 6,014 units in stock and is packaged in bulk format.

Compliance and Regulatory Considerations: Both parts share identical ECCN (EAR99) and HTSUS (8536.69.8000) classifications, indicating equivalent export control and tariff treatment. The moisture sensitivity level (MSL 1 - Unlimited) is identical for both parts, confirming equivalent handling and storage requirements. REACH status is vendor-undefined for both parts.

Selection Basis: Part selection should be determined by the specific regulatory and compliance requirements of the end application. The mechanical and electrical performance characteristics are functionally equivalent between the two parts. The contact finish composition (tin-lead versus tin) is the primary technical differentiator, with the tin finish in the 3-640443-7 providing RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Are the 640443-7 and 3-640443-7 mechanically interchangeable?

A: Yes. Both parts are mechanically interchangeable. They share identical pitch (0.100"), position count (7), mounting type (Free Hanging In-Line/Right Angle), fastening type (Locking Ramp), and closed-end configuration. Physical dimensions and mating interfaces are identical.

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

A: The contact finish composition differs between the two parts. The 640443-7 uses tin-lead, while the 3-640443-7 uses tin. Both finishes maintain the same thickness (80.0µin / 2.03µm) and provide equivalent electrical performance for IDC termination applications. The tin finish in the 3-640443-7 enables RoHS compliance.

Q: Can I use the 3-640443-7 as a direct replacement for the 640443-7 in existing designs?

A: Yes, the 3-640443-7 functions as a direct substitute for the 640443-7 in all electrical and mechanical aspects. The primary consideration is regulatory compliance: if your application requires RoHS compliance, the 3-640443-7 is the appropriate choice. If RoHS compliance is not required, either part is suitable.

Q: What does IDC termination mean, and is it the same for both parts?

A: IDC (Insulation Displacement Contact) termination is a method where the connector contacts pierce the insulation of the wire without requiring stripping. Both the 640443-7 and 3-640443-7 use identical IDC termination for 28 AWG discrete or ribbon cable, ensuring equivalent installation and performance.

Q: Are there any differences in packaging between these two parts?

A: The 640443-7 is supplied in standard packaging, while the 3-640443-7 is supplied in bulk packaging. This is a logistical difference only and does not affect the electrical or mechanical performance of the connector.

Q: What is the moisture sensitivity level, and does it differ between the two parts?

A: Both parts have an MSL (Moisture Sensitivity Level) of 1, which indicates unlimited moisture sensitivity. This means both parts can be stored and handled without special moisture control measures, and there is no difference in handling requirements between the two parts.

Q: Which part should I specify for a new design?

A: For new designs, specify the 3-640443-7 if RoHS compliance is required by your application, regulatory framework, or customer specifications. If RoHS compliance is not a requirement, either part is suitable. The 3-640443-7 also offers higher inventory availability (6,014 units versus 1,046 units).

Q: Are the ECCN and HTSUS classifications the same for both parts?

A: Yes. Both parts share identical ECCN (EAR99) and HTSUS (8536.69.8000) classifications, indicating equivalent export control and tariff treatment. There are no differences in regulatory classification between the two parts.
