TE Connectivity 643816-5 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 643816-5 is a 5-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 28 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 733 pieces available in new original inventory.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across connector specifications. Alternative part numbers may be necessary due to inventory availability, packaging requirements, or compliance status differences while preserving functional compatibility in the application circuit.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 643816-5 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Receptacle)
• Number of positions (5)
• Contact type (Female Socket)
• Pitch spacing (0.100" / 2.54mm)
• Cable termination method (IDC)
• Wire gauge compatibility (28 AWG)
• Wire type acceptance (Discrete or Ribbon Cable)

Mechanical Compatibility Parameters:

• Number of rows (1)
• Mounting configuration (Free Hanging In-Line, Right Angle)
• Fastening mechanism (Locking Ramp)
• Closed-end design
• Contact finish thickness (80.0µin / 2.03µm)

Environmental & Compliance Parameters:

• Moisture Sensitivity Level (MSL 1)
• Series designation (MTA-100)

The substitute part 3-643816-5 maintains full equivalence across all electrical and mechanical parameters. Differences exist only in contact finish material composition (tin versus tin-lead), packaging format (bulk versus standard), and regulatory compliance status (RoHS3 compliant versus non-compliant).

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: TE Connectivity 643816-5

The 643816-5 is the original specification part and remains the first choice for applications where the exact part number is documented in design specifications or where tin-lead contact finish is explicitly required. This part is active in production with adequate inventory availability.

Alternative Selection: TE Connectivity 3-643816-5

The 3-643816-5 substitute part is functionally equivalent across all electrical and mechanical parameters and is suitable for direct substitution in applications where:

1. RoHS3 Compliance is Required: The substitute part meets RoHS3 compliance requirements, whereas the main part is RoHS non-compliant. Applications subject to RoHS3 regulatory requirements must use the 3-643816-5.

2. Tin Contact Finish is Acceptable: The substitute part features tin contact finish instead of tin-lead. Both finishes maintain the specified 80.0µin (2.03µm) thickness and are compatible with IDC termination for 28 AWG cable.

3. Bulk Packaging is Acceptable: The substitute part is supplied in bulk packaging format, which may be advantageous for high-volume production environments.

4. Higher Inventory Availability is Needed: The substitute part has significantly higher inventory (3282 pieces versus 733 pieces), providing greater availability for immediate procurement.

Both parts are active products from the same manufacturer and series, ensuring design continuity and long-term supply stability.

Frequently Asked Questions (FAQ)

Q: Can the 3-643816-5 be used as a direct replacement for the 643816-5 in existing designs?

A: Yes. The 3-643816-5 maintains full electrical and mechanical equivalence with the 643816-5 across all critical parameters including connector type, position count, pitch, contact type, IDC termination method, wire gauge, mounting configuration, and fastening mechanism. The primary differences are contact finish material (tin versus tin-lead) and RoHS compliance status.

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

A: Both finishes are applied at the same thickness (80.0µin / 2.03µm) and are compatible with IDC termination. Tin-lead finish (643816-5) contains lead as an alloying element, while tin finish (3-643816-5) is pure tin. The tin finish is RoHS3 compliant, whereas tin-lead is not. Both finishes provide equivalent electrical conductivity and contact reliability for this connector application.

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

A: No compatibility issues exist. Both parts are from the same MTA-100 series, feature identical pitch spacing (0.100" / 2.54mm), identical mounting types (free-hanging in-line and right-angle), and identical fastening mechanisms (locking ramp). They accept the same cable types (discrete or ribbon) at the same wire gauge (28 AWG).

Q: What does the packaging difference mean?

A: The main part (643816-5) uses standard packaging, while the substitute (3-643816-5) uses bulk packaging. Bulk packaging typically involves larger quantities per container, which is advantageous for high-volume manufacturing operations but may not be suitable for applications requiring smaller quantities or specific packaging formats.

Q: Which part should be selected for new designs?

A: For new designs, the 3-643816-5 is recommended when RoHS3 compliance is a design requirement or when regulatory standards mandate lead-free components. The 643816-5 remains appropriate for applications where RoHS compliance is not required and tin-lead finish is specified.

Q: Is the Moisture Sensitivity Level the same for both parts?

A: Yes. Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or use.

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

A: Yes. Both the 643816-5 and 3-643816-5 accept discrete or ribbon cable at 28 AWG wire gauge, providing flexibility in cable assembly options.
