TE Connectivity 643813-7 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 643813-7 is a 7-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 22 AWG discrete or ribbon cable. This connector features tin-lead contact finish, a closed-end design, and free-hanging or right-angle mounting configuration with locking ramp fastening. The part is currently active in production with 918 pieces in stock inventory.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across connector specifications. Identifying suitable alternatives is necessary for supply chain flexibility, inventory optimization, and design standardization across manufacturing environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 643813-7 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Receptacle)
• Number of positions (7)
• Contact type (Female Socket)
• Pitch spacing (0.100" / 2.54mm)
• Cable termination method (IDC)
• Wire gauge compatibility (22 AWG)
• Contact finish thickness (80.0µin / 2.03µm)

Mechanical Compatibility Parameters:

• Number of rows (1)
• Mounting type (Free Hanging In-Line, Right Angle)
• Fastening type (Locking Ramp)
• Closed-end design
• Series designation (MTA-100)

Environmental Parameters:

• Moisture Sensitivity Level (MSL 1 - Unlimited)
• ECCN classification (EAR99)
• HTSUS code (8536.69.8000)

The substitute part 3-643813-7 maintains full equivalence across all electrical and mechanical parameters. The primary distinction is the contact finish specification (tin versus tin-lead) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Part 643813-7 (Tin-Lead Contact Finish): This part is suitable for applications where tin-lead contact finish is specified or required by design documentation. The part is active in production and maintains full inventory availability. RoHS non-compliance status applies to applications not subject to RoHS restrictions.

Part 3-643813-7 (Tin Contact Finish - Recommended for RoHS Compliance): This substitute part is recommended for applications requiring RoHS compliance. The tin contact finish eliminates lead content while maintaining identical electrical and mechanical performance across all critical parameters. The substitute part demonstrates higher inventory availability (5111 pieces versus 918 pieces) and is packaged in bulk format. Both parts are active in production status and share identical MSL, ECCN, and HTSUS classifications.

Selection between these parts is determined by regulatory compliance requirements and contact finish specifications. All other functional and mechanical characteristics remain equivalent.

Frequently Asked Questions (FAQ)

Q: Are the 643813-7 and 3-643813-7 connectors mechanically interchangeable?

A: Yes. Both connectors maintain identical mechanical specifications including pitch (0.100"), number of positions (7), mounting type (free-hanging in-line and right-angle), fastening type (locking ramp), and closed-end design. Physical dimensions and mounting interfaces are equivalent.

Q: What is the difference between tin-lead and tin contact finishes in these connectors?

A: The 643813-7 features tin-lead contact finish, while the 3-643813-7 features tin contact finish. Both maintain identical contact finish thickness (80.0µin / 2.03µm). The primary distinction is the presence of lead in the tin-lead variant. Contact resistance and electrical performance remain equivalent across both finishes.

Q: Which part should be selected for RoHS-compliant applications?

A: The 3-643813-7 is RoHS compliant and is the appropriate selection for applications subject to RoHS regulations. The 643813-7 is RoHS non-compliant due to its tin-lead contact finish.

Q: Are both parts suitable for IDC termination with 22 AWG cable?

A: Yes. Both the 643813-7 and 3-643813-7 are designed for IDC termination with 22 AWG discrete or ribbon cable. Cable termination specifications are identical across both parts.

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

A: The 643813-7 is supplied with unspecified packaging, while the 3-643813-7 is supplied in bulk packaging. Both parts are available in active production status with full inventory availability.

Q: Can these connectors be used with both discrete and ribbon cable?

A: Yes. Both the 643813-7 and 3-643813-7 support discrete or ribbon cable configurations. Wire type compatibility is identical across both parts.

Q: What is the Moisture Sensitivity Level for these connectors?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are there any electrical performance differences between the substitute parts?

A: No. All electrical parameters including contact type (female socket), pitch spacing (0.100"), number of positions (7), and contact finish thickness (80.0µin) are identical. Electrical performance is equivalent across both parts.
