Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 170123-2 is based on strict electrical and mechanical parameter equivalence within the Faston quick-connect terminal family. The substitute part must satisfy all of the following criteria:

Critical Substitution Parameters:

• Tab width: 0.205" (5.21mm)
• Tab thickness: 0.020" (0.51mm)
• Tab length: 0.250" (6.35mm)
• Wire gauge compatibility: 18-22 AWG
• Termination method: Crimp
• Gender: Female
• Contact material: Brass
• Contact finish: Tin
• Insulation type: Non-Insulated
• Insulation diameter range: 0.085" ~ 0.125" (2.16mm ~ 3.18mm)
• Mounting configuration: Free Hanging (In-Line)

The substitute part 42198-2 meets all specified parameters and is classified as an Active product with current manufacturing support and significantly higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 42198-2 is the direct equivalent substitute for the obsolete 170123-2 connector. Both parts are manufactured by TE Connectivity within the Faston quick-connect terminal series and share identical electrical and mechanical specifications across all critical parameters.

Substitution Basis:

The 42198-2 maintains full dimensional and functional compatibility with the 170123-2. The overall length variance of 0.05mm (0.618" versus 0.616") is within normal manufacturing tolerance and does not affect mechanical fit or electrical performance in quick-connect applications.

Compliance Status:

Both the main part and substitute are RoHS Compliant and carry Moisture Sensitivity Level 1 (Unlimited), indicating no special handling requirements during storage or assembly.

Product Status Advantage:

The 42198-2 carries Active product status with TE Connectivity, ensuring continued manufacturing support, documented supply chain availability, and technical support. The substitute part is available in Cut Tape (CT) packaging, a standard distribution format suitable for production environments.

Inventory Availability:

The 42198-2 demonstrates significantly higher inventory availability (120,783 pieces) compared to the obsolete 170123-2 (1,129 pieces), supporting long-term component sourcing reliability.

Frequently Asked Questions (FAQ)

Q: Can the 42198-2 be used as a direct replacement for the 170123-2 in existing designs?

A: Yes. The 42198-2 is dimensionally and functionally equivalent to the 170123-2 across all critical parameters including tab width, thickness, length, wire gauge compatibility, contact material, and finish. No design modifications are required.

Q: What is the significance of the 0.05mm difference in overall length between the two parts?

A: The overall length variance (0.618" versus 0.616") falls within standard manufacturing tolerances for quick-connect terminals and does not affect mechanical fit, electrical performance, or connector mating characteristics in free-hanging in-line applications.

Q: Why is the 170123-2 listed as Obsolete?

A: The 170123-2 has been discontinued by TE Connectivity. The 42198-2 represents the current active equivalent within the Faston terminal family and is the recommended source for new production and ongoing component requirements.

Q: Are there any compliance or certification differences between the two parts?

A: No. Both parts are RoHS Compliant, carry identical Moisture Sensitivity Level 1 (Unlimited) ratings, and share the same ECCN (EAR99) and HTSUS (8536.90.4000) classifications.

Q: What packaging format is the 42198-2 supplied in?

A: The 42198-2 is available in Cut Tape (CT) packaging, a standard format for production assembly environments. The original 170123-2 packaging format was not specified in available documentation.

Q: Is the 42198-2 suitable for the same wire gauge range as the 170123-2?

A: Yes. Both parts are rated for 18-22 AWG wire gauge and accommodate insulation diameters of 0.085" to 0.125" (2.16mm to 3.18mm).

Q: What is the contact material composition for both parts?

A: Both the 170123-2 and 42198-2 feature brass contacts with tin finish, providing consistent electrical conductivity and corrosion resistance for quick-connect applications.
