TE Connectivity AMP Connectors 2-1746741-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 2-1746741-3 is a 3 Position Rectangular Socket Connector with IDC (Insulation Displacement Contact) termination, gold plating, and support for 20-26 AWG discrete wire. This connector is part of the RITS series and maintains Active product status. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory requirements necessitate alternative component selection from qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 2-1746741-3 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 3
• Pitch: 0.079" (2.00mm)
• Number of Rows: 1
• Cable Termination: IDC
• Contact Finish: Gold
• Contact Finish Thickness: 8.00µin (0.203µm)
• Mounting Type: Free Hanging (In-Line)
• Color: Black
• MSL Rating: 1 (Unlimited)

Allowable Variation Parameters:

• Wire Gauge: 20-26 AWG (substitute may support subset within this range)
• Connector Type: Socket or Receptacle (both provide female contact configuration)
• RoHS Status: ROHS3 Compliant or RoHS Compliant (both meet environmental compliance)

The 3M part 37303-3122-000 FL 100 qualifies as a substitute because it maintains all mandatory parameters while supporting wire gauge 24-26 AWG, which falls within the allowable range of the primary part.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 2-1746741-3 (Primary Part)

Selection is appropriate when ROHS3 Compliant certification is explicitly required by design specifications or regulatory requirements. This part supports the full wire gauge range of 20-26 AWG, providing maximum flexibility for discrete wire applications. Current inventory of 711 pieces supports immediate availability for production requirements.

3M 37303-3122-000 FL 100 (Substitute Part)

Selection is appropriate when RoHS Compliant certification satisfies design requirements and wire gauge application is limited to 24-26 AWG. The Mini-Clamp I, 373 series designation indicates this part incorporates a closed-end feature. Higher inventory availability of 1334 pieces supports extended production runs. REACH Unaffected status provides additional environmental compliance documentation.

Both parts maintain identical pitch, position count, contact finish specifications, and MSL ratings, ensuring mechanical and electrical compatibility within the specified wire gauge parameters.

Frequently Asked Questions (FAQ)

Q: Can the 3M 37303-3122-000 FL 100 substitute for the TE Connectivity 2-1746741-3 in all applications?

A: Substitution is valid when the application wire gauge requirement is 24-26 AWG. If the design requires support for 20-22 AWG wire, the TE Connectivity part is required. Both parts maintain identical pitch (0.079"), position count (3), and contact finish specifications.

Q: What is the difference between Socket and Receptacle connector types in this comparison?

A: Both designations indicate female contact configuration in this product category. The Socket designation (TE Connectivity) and Receptacle designation (3M) are manufacturer-specific terminology for functionally equivalent female contact connectors with IDC termination.

Q: Are there compliance differences between ROHS3 Compliant and RoHS Compliant status?

A: ROHS3 Compliant represents the current regulatory standard (Directive 2011/65/EU as amended). RoHS Compliant indicates compliance with the directive but does not specify the version. Both statuses confirm absence of restricted substances. Design specifications should clarify if ROHS3 certification is mandatory.

Q: What does the closed-end feature on the 3M part indicate?

A: The closed-end feature on the 3M 37303-3122-000 FL 100 indicates the connector housing has sealed ends, providing additional protection against contamination and mechanical damage compared to open-end designs.

Q: Are the contact finish thicknesses identical between both parts?

A: Yes. Both the TE Connectivity 2-1746741-3 and 3M 37303-3122-000 FL 100 specify 8.00µin (0.203µm) gold contact finish thickness, ensuring equivalent electrical performance and durability characteristics.

Q: What packaging format is used for both parts?

A: Both parts are supplied in Bulk packaging format, suitable for automated assembly and high-volume production environments.
