TE Connectivity AMP Connectors 3-643828-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 3-643828-2 is a 2 Position Rectangular Receptacle Connector designed for IDC (Insulation Displacement Contact) termination with 26 AWG wire. This connector is part of the MTA-100 series and features tin contact finish with a closed end design. The product is currently active and in stock with 1106 pieces available.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across connector specifications. Alternative models become necessary when primary part availability changes, supply chain requirements shift, or when design flexibility permits component standardization across multiple connector series.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 3-643828-2 is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Number of positions (2), wire gauge (26 AWG), and pitch (0.100" / 2.54mm) must be identical. These parameters ensure electrical compatibility and proper mating with corresponding connector halves.

Mechanical Parameters: Connector type (Receptacle), contact type (Female Socket), number of rows (1), mounting type (Free Hanging In-Line, Right Angle), and fastening type (Locking Ramp) must match exactly. These parameters ensure physical compatibility and proper installation.

Material & Design Parameters: Cable termination method (IDC), contact finish (Tin), and closed end design must be maintained. These parameters ensure proper wire termination and connector integrity.

Compliance Parameters: RoHS3 compliance and MSL 1 rating must be present in substitute parts to maintain regulatory and environmental standards.

The Adam Tech MTD-A-02-E-2 meets all substitution criteria across these parameter categories.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 3-643828-2 and Adam Tech MTD-A-02-E-2 are active products with full ROHS3 compliance and MSL 1 environmental ratings. Selection between these parts is based on availability and application requirements.

The TE Connectivity 3-643828-2 is the primary specification part with 1106 units in stock. This part maintains the MTA-100 series designation and is suitable for applications requiring TE Connectivity component standardization.

The Adam Tech MTD-A-02-E-2 is a functionally equivalent substitute with 2727 units in stock, providing increased availability. This part is suitable for applications where cross-manufacturer component substitution is permitted and where higher inventory levels are advantageous for supply chain planning.

Both parts maintain identical electrical and mechanical specifications across all critical parameters. The only non-functional difference is connector color (Black versus Blue), which does not affect electrical performance or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Adam Tech MTD-A-02-E-2 be used as a direct replacement for the TE Connectivity 3-643828-2?

A: Yes. Both connectors are 2 Position Rectangular Receptacles with IDC termination, 26 AWG wire gauge, 0.100" pitch, tin contact finish, and locking ramp fastening. All electrical and mechanical parameters are equivalent. The connectors are functionally interchangeable in applications where cross-manufacturer substitution is permitted.

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

A: No compatibility concerns exist for the specified electrical and mechanical parameters. Both connectors use identical IDC termination, wire gauge, pitch, and mounting specifications. The color difference (Black versus Blue) is cosmetic and does not affect connector function or mating characteristics.

Q: What is the significance of the 0.100" pitch specification?

A: The 0.100" (2.54mm) pitch specifies the center-to-center distance between connector positions. This parameter must match exactly between mating connector halves. Both the TE Connectivity and Adam Tech parts maintain this pitch specification, ensuring proper alignment and contact engagement.

Q: Why is the IDC cable termination method important for substitution?

A: IDC (Insulation Displacement Contact) termination is a specific wire connection method where the connector pierces the wire insulation without stripping. Both substitute parts use identical IDC termination, ensuring that existing cable assemblies and termination equipment are compatible with either connector.

Q: Does the wire gauge specification limit substitution options?

A: Yes. The 26 AWG specification defines the wire diameter that the connector contacts are designed to accept. Substitute parts must maintain this specification to ensure proper contact pressure, electrical conductivity, and mechanical retention. Both parts are rated for 26 AWG wire.

Q: What does ROHS3 compliance indicate for these connectors?

A: ROHS3 compliance indicates that the connectors meet Restriction of Hazardous Substances Directive requirements, restricting the use of specific hazardous materials including lead, cadmium, and mercury. Both parts maintain ROHS3 compliance, suitable for applications with environmental and regulatory requirements.

Q: How does Moisture Sensitivity Level 1 affect connector handling and storage?

A: MSL 1 (Unlimited) indicates that the connectors have no moisture sensitivity restrictions. These parts do not require special dry storage conditions, desiccant packaging, or bake-out procedures prior to soldering or assembly. Both parts can be stored and handled under standard environmental conditions.

Q: Are there differences in contact finish thickness between these parts?

A: The TE Connectivity 3-643828-2 specifies contact finish thickness of 80.0µin (2.03µm). The Adam Tech MTD-A-02-E-2 does not provide contact finish thickness specification in available documentation. Both parts use tin contact finish, which provides equivalent corrosion resistance and electrical conductivity for IDC applications.
