TE Connectivity 166052-1 D-Sub Socket Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 166052-1 is an AMPLIMITE HDP-20 series D-Sub female socket contact designed for signal applications in D-shaped connector assemblies. This component features a stamped phosphor bronze contact with gold plating and crimp termination for wire gauges 24-28 AWG. The part maintains Active product status and is ROHS3 compliant, making it suitable for current production and replacement applications. Substitute parts are identified when equivalent electrical and mechanical parameters are required but alternative contact form specifications or inventory considerations necessitate component alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for D-Sub socket contacts is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Series designation (AMPLIMITE HDP-20)
• Contact type (Female Socket)
• Wire gauge range (24-28 AWG)
• Contact termination method (Crimp)
• Contact material (Phosphor Bronze)
• Contact finish specification (Gold plating at 30.0µin)
• Contact size (20 DF)
• Signal type classification
• RoHS compliance level (ROHS3)

Allowable Variation:

• Contact form (Stamped vs. Machined) represents a manufacturing process difference that does not affect electrical or mechanical compatibility when all other parameters remain equivalent.

The substitute part 5-166052-1 maintains full equivalence across all mandatory parameters while utilizing a machined contact form instead of stamped construction. Both parts are manufactured by TE Connectivity within the same AMPLIMITE HDP-20 series and deliver identical electrical performance and mechanical fit characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the 166052-1 and 5-166052-1 are Active status products manufactured by TE Connectivity and maintain full ROHS3 compliance. Selection between these parts is based on availability and contact form preference:

166052-1 (Stamped Contact Form): Primary selection when stamped contact construction is specified or preferred. Current inventory of 6516 pieces supports high-volume applications.

5-166052-1 (Machined Contact Form): Direct substitute when stamped form availability is limited or when machined contact construction is required. Current inventory of 1492 pieces supports standard production requirements.

Both parts deliver equivalent electrical performance, mechanical fit, and environmental compliance. The contact form difference (stamped vs. machined) represents a manufacturing process variation that does not affect functional compatibility within AMPLIMITE HDP-20 series D-Sub connector assemblies.

Frequently Asked Questions (FAQ)

Q: Can 5-166052-1 be used as a direct replacement for 166052-1 in existing designs?

A: Yes. The 5-166052-1 maintains identical electrical and mechanical specifications across all critical parameters including wire gauge, contact material, gold plating thickness, contact size, and termination method. The machined contact form is functionally equivalent to the stamped form within the AMPLIMITE HDP-20 series.

Q: What is the difference between stamped and machined contact forms?

A: Stamped contacts are formed through stamping processes, while machined contacts are produced through machining operations. Both manufacturing methods produce contacts that meet identical electrical and mechanical performance specifications for this product category. The selection between forms is typically driven by cost, lead time, or design preference rather than functional requirements.

Q: Are both parts suitable for 24-28 AWG wire applications?

A: Yes. Both 166052-1 and 5-166052-1 are specified for 24-28 AWG wire gauge range with crimp termination. The wire gauge compatibility is identical between both parts.

Q: Do both parts have the same gold plating specification?

A: Yes. Both parts feature gold contact finish at 30.0µin (0.76µm) thickness with tin termination finish. The plating specifications are identical.

Q: What is the MSL rating for these parts?

A: Both parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity limitations for storage or handling.

Q: Are both parts ROHS3 compliant?

A: Yes. Both 166052-1 and 5-166052-1 are ROHS3 compliant and suitable for applications requiring RoHS compliance.

Q: Can these parts be used interchangeably in the same connector assembly?

A: Yes. Both parts are designed for the AMPLIMITE HDP-20 series and maintain identical contact size (20 DF), contact type (Female Socket), and mechanical fit specifications. They are mechanically and electrically interchangeable within this series.
