TE Connectivity 174516-1 Rectangular Connector Plug Housing - Equivalent & Substitute Parts

Part Overview

The TE Connectivity 174516-1 is a 26-position rectangular connector plug housing from the Multi-Lock series. This component serves as the housing assembly for female socket contacts in applications requiring free-hanging, in-line connector configurations. The part is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified to provide alternative housing options when the primary part is unavailable or when specific color or material variants are required for system integration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 174516-1 is determined by strict equivalence across the following critical parameters:

• Connector Type: Plug housing configuration
• Contact Type: Female socket accommodation
• Number of Positions: 26-position capacity
• Number of Rows: 2-row arrangement
• Row Spacing: 0.205" (5.20mm) center-to-center distance
• Mounting Type: Free hanging, in-line orientation
• Contact Termination: Crimp-style termination
• Fastening Type: Latch holder mechanism
• Insulation Material: Polybutylene Terephthalate (PBT)
• Operating Temperature Range: -30°C ~ 105°C
• Base Product Number: 174516 series designation

The substitute part 174516-6 maintains identical electrical and mechanical specifications across all critical parameters. The primary distinction is the housing color variant (Gray versus White), which does not affect functional compatibility or electrical performance. Both parts are sourced from the same manufacturer and series, ensuring mechanical interchangeability within the Multi-Lock connector system.

Parameter Comparison

Engineering Selection Recommendations

Both the 174516-1 and 174516-6 are Active product status components with full regulatory compliance. The 174516-1 carries RoHS3 certification, while the 174516-6 carries RoHS compliance designation. Both parts maintain identical electrical and mechanical specifications, including operating temperature range, contact configuration, and termination methodology.

Selection between these parts is determined by application-specific requirements:

• 174516-1 (White housing): Select when system design or assembly documentation specifies white connector housings or when color coding is used for circuit identification.
• 174516-6 (Gray housing): Select when system design specifies gray connector housings or when gray color coding is required for circuit identification.

Both parts are suitable for applications operating within the -30°C to 105°C temperature range and are compatible with crimp-terminated female socket contacts. The choice between these substitutes does not affect electrical performance, mechanical fit, or functional reliability within the Multi-Lock connector system.

Frequently Asked Questions (FAQ)

Q: Can 174516-6 be used as a direct replacement for 174516-1?

A: Yes. The 174516-6 is a direct functional equivalent to the 174516-1. Both parts share identical specifications for connector type, position count, row configuration, row spacing, mounting type, contact termination, fastening mechanism, insulation material, and operating temperature range. The only difference is the housing color (Gray versus White).

Q: Does the color difference affect electrical performance?

A: No. Housing color is a cosmetic and identification feature only. It does not affect electrical conductivity, signal integrity, or mechanical performance. Both white and gray housings are manufactured from the same PBT insulation material with identical electrical properties.

Q: Are these parts mechanically interchangeable?

A: Yes. Both parts maintain identical mechanical specifications including row spacing (0.205" / 5.20mm), mounting configuration (free hanging, in-line), and fastening type (latch holder). They are fully interchangeable within the Multi-Lock connector system.

Q: What is the significance of the different RoHS designations?

A: The 174516-1 carries RoHS3 certification, while the 174516-6 carries RoHS compliance designation. Both meet regulatory requirements for hazardous substance restrictions. Selection should be based on specific regulatory requirements of the end application or region.

Q: Do these housings include contacts?

A: No. Both the 174516-1 and 174516-6 are housing assemblies only. Contacts are not included and must be sourced separately. The housings are designed to accommodate crimp-terminated female socket contacts.

Q: What is the significance of MSL Level 1?

A: Moisture Sensitivity Level 1 (Unlimited) indicates that these connector housings have no moisture sensitivity restrictions. They can be stored and handled under standard environmental conditions without special moisture control measures or shelf-life limitations.

Q: Can I mix white and gray housings in the same assembly?

A: Yes, from a functional standpoint. Both parts are electrically and mechanically identical. However, mixing colors may conflict with system design specifications or color-coding conventions used for circuit identification. Verify application documentation before mixing housing colors.
