TE Connectivity 1-172341-9 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-172341-9 is a 12-position rectangular connector plug housing from the Mini-Universal MATE-N-LOK series. This component features a 0.163" (4.14mm) pitch configuration with three rows and is designed for crimp contact termination with latch lock fastening. The part is currently classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations. The connector operates across a temperature range of -20°C to 105°C and is constructed from Polyamide (PA66) Nylon 6/6 insulation material.

Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector housings is determined by strict alignment of electrical and mechanical parameters. The following criteria establish compatibility between the main part 1-172341-9 and its substitute options:

Critical Substitution Parameters:

• Number of Positions: 12
• Pitch: 0.163" (4.14mm)
• Number of Rows: 3
• Row Spacing: 0.163" (4.14mm)
• Connector Type: Plug
• Contact Termination: Crimp
• Fastening Type: Latch Lock
• Mounting Type: Free Hanging (In-Line)
• Operating Temperature Range: -20°C ~ 105°C
• Moisture Sensitivity Level: 1 (Unlimited)

All substitute parts listed maintain these core electrical and mechanical parameters. Variations in color, series designation, and product status are noted but do not affect functional interchangeability within the specified parameter set. The insulation material composition may vary between Polyamide (PA66) Nylon 6/6 and Polyamide (PA) Nylon formulations while maintaining equivalent performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity 172170-1

The 172170-1 is the recommended substitute for the obsolete 1-172341-9. This part maintains identical electrical and mechanical specifications, including the same Mini-Universal MATE-N-LOK series designation, 12-position configuration, 0.163" (4.14mm) pitch, and operating temperature range of -20°C to 105°C. The 172170-1 is currently in active product status with 7,767 pieces available in inventory. The primary difference is color (Natural versus Black) and packaging format (Bulk). Both parts are RoHS compliant and feature MSL 1 (Unlimited) moisture sensitivity rating.

Secondary Substitutes: TE Connectivity 794200-1 and 794253-1

The 794200-1 and 794253-1 are parametric equivalents from the Mini-Universal MATE-N-LOK II series. These parts maintain all critical electrical and mechanical parameters including 12 positions, 0.163" (4.14mm) pitch, three-row configuration, and latch lock fastening. Both parts are currently in active product status. The 794200-1 carries RoHS compliance, while the 794253-1 carries ROHS3 compliance. Operating temperature specifications are not provided for these parts. The insulation material is specified as Polyamide (PA) Nylon rather than the PA66 Nylon 6/6 formulation of the original part.

Compliance Considerations

All substitute parts maintain MSL 1 (Unlimited) moisture sensitivity rating and are RoHS compliant. The 1-172341-9 and 794253-1 both carry ROHS3 certification, while 172170-1 and 794200-1 carry standard RoHS compliance. Selection should account for specific regulatory requirements of the application.

Frequently Asked Questions (FAQ)

Q: Can the 172170-1 directly replace the obsolete 1-172341-9?

A: Yes. The 172170-1 maintains identical electrical and mechanical specifications across all critical parameters including position count, pitch, row configuration, operating temperature range, and fastening mechanism. The only functional difference is housing color (Natural versus Black). Both parts are compatible with the same contact sets and mounting configurations.

Q: What is the difference between the Mini-Universal MATE-N-LOK and MATE-N-LOK II series?

A: The series designation indicates product line evolution. Both series maintain the same electrical and mechanical interface parameters for the 12-position, 0.163" (4.14mm) pitch configuration. The MATE-N-LOK II represents a newer product line iteration. Substitution between series is valid when all critical parameters align.

Q: Does the color difference between Black (1-172341-9) and Natural (172170-1, 794200-1, 794253-1) affect compatibility?

A: Color is a cosmetic parameter and does not affect electrical or mechanical compatibility. Selection of color should be based on application requirements and visual identification needs.

Q: Why are operating temperature specifications not provided for 794200-1 and 794253-1?

A: Operating temperature data is not included in the provided specifications for these parts. When operating temperature range is a critical design parameter, the 172170-1 is the preferred substitute as it specifies the same -20°C to 105°C range as the original 1-172341-9.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates that the component has unlimited shelf life and does not require special moisture control during storage or handling. This applies to all listed parts and represents the least restrictive moisture sensitivity classification.

Q: Are contacts included with these connector housings?

A: No. All listed parts are connector housings only. Contacts must be sourced separately and crimped into the housing according to TE Connectivity specifications.

Q: What packaging options are available?

A: The original 1-172341-9 is available in standard packaging. The substitute parts 172170-1, 794200-1, and 794253-1 are available in Bulk packaging format.

Q: Can I use 794200-1 or 794253-1 if operating temperature specification is critical to my application?

A: If the -20°C to 105°C operating temperature range is a mandatory design requirement, use 172170-1, which explicitly specifies this range. The 794200-1 and 794253-1 do not provide operating temperature data in the available specifications.
