TE Connectivity 170455-2 Quick Connect Female Crimp Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 170455-2 is a 0.250" (6.35mm) Quick Connect Female crimp connector designed for 14-18 AWG wire gauges. This non-insulated terminal belongs to the Mark II series and is classified as obsolete. The part is manufactured from brass with tin contact finish and operates as a free-hanging in-line connector for quick-disconnect applications.

Due to its obsolete product status, locating equivalent or substitute components is necessary for ongoing production, maintenance, and repair applications. Active alternatives within the same series and specification range are available to ensure continuity of supply and design compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 170455-2 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Tab width: 0.250" (6.35mm)
• Tab thickness: 0.032" (0.81mm)
• Wire gauge range: 14-18 AWG
• Gender: Female
• Termination method: Crimp
• Insulation type: Non-Insulated
• Mounting configuration: Free Hanging (In-Line)
• Overall length: 0.898" (22.80mm)
• Insulation diameter range: 0.087" ~ 0.134" (2.21mm ~ 3.40mm)
• Contact material: Brass
• Series designation: Mark II

The substitute part 170454-1 maintains full electrical and mechanical compatibility with the main part across all specified parameters. The primary distinction is product status: 170455-2 is obsolete while 170454-1 is active, with improved inventory availability.

Engineering Selection Recommendations

The TE Connectivity 170454-1 is the direct substitute for the obsolete 170455-2 connector. Selection of 170454-1 is supported by the following engineering factors:

Product Status: The 170454-1 maintains active product status with TE Connectivity, ensuring ongoing availability and manufacturing support. The 170455-2 is classified as obsolete, presenting supply chain risk for new production and long-term maintenance applications.

Regulatory Compliance: Both parts maintain identical ROHS3 compliance and EAR99 export classification, confirming equivalent environmental and trade regulatory standing.

Electrical and Mechanical Specifications: Complete parameter equivalence across tab dimensions, wire gauge capacity, contact material, and termination method ensures direct functional interchangeability without design modification.

Inventory Availability: The 170454-1 demonstrates superior inventory position (2100 pieces) compared to the 170455-2 (1032 pieces), supporting production continuity and reduced lead times.

Packaging Consideration: The 170454-1 is supplied in Cut Tape (CT) packaging, which is standard for component distribution and integration into automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can 170454-1 be used as a direct replacement for 170455-2 in existing designs?

A: Yes. The 170454-1 is electrically and mechanically equivalent to 170455-2 across all specified parameters. No design modification is required for substitution.

Q: What is the primary reason for substituting 170455-2 with 170454-1?

A: The 170455-2 is classified as obsolete, while 170454-1 is an active product. Substitution ensures continued supply availability and manufacturing support from TE Connectivity.

Q: Are the contact materials and finishes identical between these parts?

A: Both parts use brass contact material. The 170455-2 specifies tin contact finish; the 170454-1 contact finish specification is not provided in the available data. Verify contact finish requirements with TE Connectivity if finish specification is critical to your application.

Q: Do these connectors have the same wire gauge capacity?

A: Yes. Both 170455-2 and 170454-1 are rated for 14-18 AWG wire gauges with identical insulation diameter ranges of 0.087" to 0.134" (2.21mm to 3.40mm).

Q: What is the difference in packaging between these parts?

A: The 170455-2 packaging is not specified in available documentation. The 170454-1 is supplied in Cut Tape (CT) packaging, which is standard for component distribution and automated assembly integration.

Q: Are both parts RoHS compliant?

A: Yes. Both 170455-2 and 170454-1 are ROHS3 compliant with MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions.

Q: Can these connectors be used interchangeably in quick-disconnect applications?

A: Yes. Both parts are designed for free-hanging in-line mounting in quick-connect applications with identical 0.250" (6.35mm) tab width and 0.032" (0.81mm) tab thickness specifications.
