TE Connectivity 1-643813-7 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-643813-7 is a 17-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 a locking ramp fastening mechanism. The part is currently active in production with 1,077 units in stock.

Substitute parts are identified when equivalent connectors maintain identical electrical and mechanical specifications while offering alternative packaging, compliance status, or contact finish materials. Identifying suitable alternatives ensures design flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 1-643813-7 is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must remain identical for a part to qualify as a direct substitute:

Critical Matching Parameters:

• Connector type (Receptacle)
• Number of positions (17)
• Pitch spacing (0.100" / 2.54mm)
• Contact type (Female Socket)
• Cable termination method (IDC)
• Wire gauge (22 AWG)
• Mounting configuration (Free Hanging In-Line, Right Angle)
• Fastening mechanism (Locking Ramp)
• Series designation (MTA-100)

Variable Parameters Permitting Substitution:

• Contact finish material (Tin-Lead vs. Tin)
• Packaging configuration (standard vs. bulk)
• RoHS compliance status

The substitute part 4-643813-7 maintains complete equivalence across all critical parameters while differing in contact finish composition (Tin vs. Tin-Lead) and RoHS compliance status (Compliant vs. Non-Compliant).

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (1-643813-7): The 1-643813-7 is suitable for applications where tin-lead contact finish is specified or required by design documentation. This part is RoHS non-compliant and appropriate for legacy systems or applications without RoHS regulatory requirements. Current inventory of 1,077 units supports immediate availability.

Substitute Part Selection (4-643813-7): The 4-643813-7 provides functional equivalence with RoHS compliance, making it the appropriate choice for new designs, products destined for markets with RoHS mandates, or applications requiring lead-free contact materials. The tin contact finish maintains electrical performance and contact reliability equivalent to the tin-lead variant. Inventory of 610 units is available in bulk packaging.

Compliance Considerations: Selection between these parts should be driven by regulatory requirements and design specifications. The RoHS-compliant variant (4-643813-7) is recommended for new product development and applications subject to EU Directive 2011/65/EU or equivalent regional regulations. The non-compliant variant (1-643813-7) remains valid for applications explicitly exempted from RoHS requirements or where legacy specifications mandate tin-lead finishes.

Frequently Asked Questions (FAQ)

Q: Can the 4-643813-7 be used as a direct replacement for the 1-643813-7 in existing designs?

A: Yes. The 4-643813-7 maintains identical electrical and mechanical specifications across all critical parameters including connector type, position count, pitch, termination method, wire gauge, and mounting configuration. The primary difference is the contact finish material (tin vs. tin-lead) and RoHS compliance status. Substitution is electrically and mechanically valid.

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

A: Both contact finishes provide equivalent electrical conductivity and contact reliability within the MTA-100 series specifications. The tin finish (4-643813-7) is lead-free and RoHS compliant, while the tin-lead finish (1-643813-7) contains lead. Selection depends on regulatory compliance requirements and design specifications rather than electrical performance.

Q: Are there packaging differences between these substitute parts?

A: The 1-643813-7 is supplied in standard packaging, while the 4-643813-7 is supplied in bulk packaging. Both parts are identical in form, fit, and function. Packaging selection should be based on inventory management and procurement requirements.

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

A: The 4-643813-7 is recommended for new designs due to its RoHS compliance status, which aligns with current regulatory standards and manufacturing practices. This part supports compliance with EU Directive 2011/65/EU and equivalent regulations in other regions.

Q: Are both parts currently in active production?

A: Yes. Both the 1-643813-7 and 4-643813-7 maintain active product status with TE Connectivity. Current inventory levels are 1,077 units and 610 units respectively, supporting both immediate availability and ongoing supply.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts carry a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without special moisture control measures. Standard storage conditions are appropriate for both variants.
