TE Connectivity 1703061-3 Rectangular Connector Plug Housing Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1703061-3 is a 2-position rectangular connector plug housing from the Universal MATE-N-LOK series. This component is designed for free-hanging, in-line applications with crimp contact termination and latch holder fastening. The part is actively manufactured and RoHS compliant. Substitute parts are identified when equivalent electrical and mechanical parameters are required for applications where the original part number is unavailable, inventory constraints exist, or alternative material specifications are acceptable within the defined operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1703061-3 are identified based on strict equivalence across the following critical parameters:

Electrical and Mechanical Equivalence Criteria:

• Connector Type: Plug
• Number of Positions: 2
• Number of Rows: 1
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Latch Holder
• Series: Universal MATE-N-LOK
• Base Product Number: 1703061

Allowable Variations:

• Insulation Material: Polyamide variants (PA6 or PA66)
• Operating Temperature Range: Equal to or exceeding the main part specification
• Color: Different housing colors (Red, Natural)
• REACH Status: Variations permitted

All substitute parts maintain the same connector architecture, contact interface, and mounting characteristics, ensuring mechanical and electrical compatibility within the Universal MATE-N-LOK ecosystem.

Parameter Comparison

Engineering Selection Recommendations

1703061-3 (Red Housing, PA6 Material)

Use the original 1703061-3 when red housing color is a functional or identification requirement. This part maintains PA6 polyamide insulation material with an operating temperature range of -55°C to 105°C. All regulatory certifications are current and active.

1-1703061-2 (Natural Housing, PA66 Material)

The 1-1703061-2 substitute offers an extended operating temperature range of -55°C to 125°C through PA66 polyamide material composition. This part is suitable for applications requiring higher thermal performance. Housing color is natural rather than red. RoHS compliance and MSL rating are equivalent to the main part. Inventory availability is significantly higher (52,033 pieces).

1703061-1 (Natural Housing, PA6 Material)

The 1703061-1 substitute maintains the same PA6 polyamide material and -55°C to 105°C operating temperature range as the main part. Housing color is natural. This part is suitable for direct functional replacement when color differentiation is not required. RoHS compliance is confirmed with REACH Unaffected status. Inventory availability is moderate (1,333 pieces).

All three parts are active products from TE Connectivity AMP Connectors within the Universal MATE-N-LOK series and maintain full mechanical and electrical compatibility for 2-position plug housing applications.

Frequently Asked Questions (FAQ)

Q: Can 1-1703061-2 be used in place of 1703061-3 in all applications?

A: The 1-1703061-2 is mechanically and electrically compatible with 1703061-3. The primary differences are housing color (natural vs. red) and insulation material (PA66 vs. PA6). The extended operating temperature range of 1-1703061-2 (-55°C to 125°C) exceeds the 1703061-3 specification (-55°C to 105°C). Substitution is valid when red housing color is not a functional requirement.

Q: What is the difference between PA6 and PA66 insulation materials?

A: PA6 (Nylon 6) and PA66 (Nylon 6/6) are both polyamide materials used in connector housings. The 1-1703061-2 uses PA66, which provides the extended operating temperature capability to 125°C compared to the PA6 material in 1703061-3 and 1703061-1, which operate to 105°C. Both materials are RoHS compliant and maintain MSL 1 rating.

Q: Are contacts included with these connector housings?

A: No. All three parts (1703061-3, 1-1703061-2, and 1703061-1) are connector housings only. Contacts are not included and must be sourced separately for crimp termination.

Q: What is the significance of the Universal MATE-N-LOK series designation?

A: The Universal MATE-N-LOK series designation indicates that all three parts share the same connector interface architecture, mating geometry, and latch holder fastening system. This ensures mechanical compatibility and interchangeability within the series for 2-position plug housing applications.

Q: Does housing color affect electrical performance?

A: Housing color is a visual identification feature and does not affect electrical performance. The red color of 1703061-3 and natural color of 1-1703061-2 and 1703061-1 are functionally equivalent from an electrical standpoint.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 (Unlimited) indicates that the component has no moisture sensitivity restrictions. These parts can be stored and handled without special moisture control measures, simplifying inventory management and logistics.

Q: Are all three parts RoHS compliant?

A: Yes. All three parts (1703061-3, 1-1703061-2, and 1703061-1) are RoHS compliant, meeting the Restriction of Hazardous Substances directive requirements.
