TE Connectivity 166294-1 D-Sub Contact Equivalent & Substitute Parts

Part Overview

The TE Connectivity 166294-1 is a D-Sub contact male pin designed for 24-28 AWG wire termination using crimp attachment. This component is classified as an AMPLIMITE HDP-20 series signal contact with gold-plated brass construction and stamped contact form. The part is currently listed as obsolete, necessitating identification of active equivalent components for ongoing applications and new designs. Substitute parts maintain functional compatibility through matching electrical and mechanical specifications while offering improved availability and active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 166294-1 is based on strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Wire gauge range: 24-28 AWG
• Contact type: Male pin
• Contact termination method: Crimp
• Contact material and finish: Brass with gold plating at 30.0µin thickness
• Series designation: AMPLIMITE HDP-20

Mechanical Compatibility Parameters:

• Contact size: 20
• Contact form: Stamped
• Insulation support feature presence

Regulatory and Environmental Parameters:

• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)

The substitute part 166054-1 maintains full equivalence across all critical parameters. Differences in packaging format (bulk versus cut tape) and product status (obsolete versus active) do not affect functional compatibility in the application circuit.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 166054-1 is the direct functional equivalent for the obsolete 166294-1 part number. Both components are manufactured by TE Connectivity within the AMPLIMITE HDP-20 series and maintain identical electrical and mechanical specifications for D-Sub male pin contact applications.

Selection Basis:

The 166054-1 substitute provides active product status with current manufacturing support, ensuring long-term availability and supply chain continuity. Both parts carry ROHS3 compliance certification and unlimited moisture sensitivity rating, meeting regulatory requirements for industrial and commercial applications.

The packaging difference between bulk (166294-1) and cut tape format (166054-1) reflects distribution channel optimization and does not impact functional performance. Selection between these formats depends on procurement volume requirements and assembly process specifications.

Frequently Asked Questions (FAQ)

Q: Can 166054-1 be used as a direct replacement for 166294-1 in existing designs?

A: Yes. The 166054-1 maintains identical electrical and mechanical specifications across all critical parameters including wire gauge, contact termination method, material composition, and finish specifications. Direct substitution is functionally compatible.

Q: What is the significance of the "DF" designation in the 166054-1 contact size specification?

A: The contact size designation "20 DF" in the substitute part represents an equivalent contact size within the AMPLIMITE HDP-20 series. This designation does not affect functional compatibility with the original 166294-1 specification.

Q: Does the packaging format difference affect component performance?

A: No. The packaging format difference (bulk versus cut tape) is a distribution and handling specification only. It does not alter the electrical or mechanical properties of the contact itself.

Q: Why is 166294-1 listed as obsolete?

A: Product obsolescence reflects TE Connectivity's manufacturing and distribution decisions. The 166054-1 represents the current active equivalent within the same series, providing equivalent functionality with ongoing manufacturer support.

Q: Are both parts RoHS compliant?

A: Yes. Both 166294-1 and 166054-1 carry ROHS3 compliance certification, meeting environmental and regulatory requirements for electronic component manufacturing and use.

Q: What wire gauges are compatible with these contacts?

A: Both parts are designed for 24-28 AWG wire termination using the crimp attachment method. Wire gauge selection must remain within this specified range for proper contact engagement and electrical performance.
