TE Connectivity AMP Connectors 170289-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 170289-2 is a socket contact connector designed for rectangular connector applications within the MIC (Multi-Interlock) series. This component is rated for 14-20 AWG wire gauges and features gold plating on the contact surface with crimp termination. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional compatibility while meeting current supply chain requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 170289-2 is determined by the following critical parameters: series designation (MIC Multi-Interlock), connector type (socket), termination method (crimp), and wire gauge compatibility (14-20 AWG). Contact finish material and product status are secondary considerations that influence application suitability.

Substitute parts are grouped into two categories:

Direct Substitutes: Parts maintaining identical wire gauge range (14-20 AWG) and socket configuration within the MIC series. These parts differ only in contact finish material (tin versus gold) and packaging format, with no impact on electrical or mechanical interface compatibility.

Similar Substitutes: Parts within the MIC series maintaining socket configuration and crimp termination but operating within an adjacent wire gauge range (18-22 AWG). These parts accommodate overlapping wire gauges but are not interchangeable for all applications requiring the full 14-20 AWG range.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (170286-1 or 170289-1):

Parts 170286-1 and 170289-1 are functionally equivalent to 170289-2 for applications requiring 14-20 AWG socket contacts with crimp termination within the MIC series. Both substitute parts are active products with ROHS3 compliance, providing superior regulatory status compared to the obsolete main part. The primary distinction between these direct substitutes is packaging format: 170286-1 is supplied in Cut Tape (CT) format with 1,411 units in stock, while 170289-1 is supplied in Bulk format with 20,745 units in stock.

Contact finish material differs between the main part (gold) and direct substitutes (tin). This material difference does not affect mechanical interface compatibility or electrical performance in standard applications. Selection between 170286-1 and 170289-1 should be based on packaging requirements and inventory availability rather than electrical characteristics.

For Wire Gauge Overlap Applications (170307-1):

Part 170307-1 operates within the 18-22 AWG wire gauge range, which overlaps with the upper portion of the 170289-2 specification (18-20 AWG). This part is suitable only for applications where wire gauges do not extend below 18 AWG. Part 170307-1 is active with ROHS3 compliance and available in Cut Tape (CT) packaging with 1,048 units in stock.

Frequently Asked Questions (FAQ)

Q: Can 170286-1 or 170289-1 be used as direct replacements for 170289-2?

A: Yes. Both 170286-1 and 170289-1 maintain identical wire gauge range (14-20 AWG), socket configuration, crimp termination, and MIC series designation. The contact finish material differs (tin versus gold), but this does not affect mechanical or electrical interface compatibility in standard rectangular connector applications.

Q: What is the difference between 170286-1 and 170289-1?

A: These parts are electrically and mechanically identical. The primary difference is packaging: 170286-1 is supplied in Cut Tape (CT) format, while 170289-1 is supplied in Bulk format. Inventory availability also differs, with 170289-1 offering significantly higher stock levels (20,745 units versus 1,411 units).

Q: When should 170307-1 be selected instead of 170286-1 or 170289-1?

A: Part 170307-1 should be selected only when the application wire gauge requirement is 18-22 AWG and does not require accommodation of 14-17 AWG conductors. The 170307-1 contact is not suitable for the full 14-20 AWG range specified for the main part.

Q: Does the tin contact finish of substitute parts affect performance compared to the gold finish of 170289-2?

A: Contact finish material does not affect mechanical interface compatibility or electrical performance in standard rectangular connector applications. Both tin and gold finishes provide adequate conductivity and corrosion resistance for MIC series socket contacts.

Q: Are all substitute parts RoHS compliant?

A: Yes. The main part 170289-2 is RoHS Compliant. All substitute parts (170286-1, 170289-1, and 170307-1) are ROHS3 Compliant, meeting current regulatory requirements.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All parts, including the main part and all substitutes, have MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
