Substitute Part Grouping Explanation

Substitution of the 1-172170-2 is determined by strict equivalence across the following critical parameters: connector type (plug), number of positions (12), pitch (0.163" / 4.14mm), number of rows (3), row spacing (0.163" / 4.14mm), mounting type (free hanging in-line), contact termination method (crimp), and fastening type (latch lock). All substitute parts maintain these core electrical and mechanical specifications.

The substitute parts are grouped into two categories based on series designation:

Mini-Universal MATE-N-LOK Series: Parts 172170-1 and 172341-1 maintain the original series classification with identical operating temperature range (-20°C ~ 105°C) and insulation material composition (Polyamide PA66, Nylon 6/6).

Mini-Universal MATE-N-LOK II Series: Parts 794200-1 and 794253-1 represent the next-generation series variant with equivalent dimensional and functional specifications. Operating temperature data is not provided for these parts. Insulation material is specified as Polyamide (PA), Nylon without specific grade designation.

All substitute parts are RoHS compliant and carry MSL rating of 1 (Unlimited).

Engineering Selection Recommendations

Primary Substitutes (Mini-Universal MATE-N-LOK Series):

Part 172170-1 is the direct equivalent to 1-172170-2 within the original series. Both maintain identical electrical and mechanical specifications, operating temperature range, and insulation material composition. The primary distinction is color (natural versus red) and product status (active versus obsolete). Part 172170-1 is recommended for applications requiring continuity with the original series specification and documented operating temperature performance.

Part 172341-1 provides equivalent functionality within the same series with identical specifications and operating temperature range. This part is suitable for applications where series consistency is required.

Secondary Substitutes (Mini-Universal MATE-N-LOK II Series):

Parts 794200-1 and 794253-1 represent the next-generation series variant. These parts maintain all critical dimensional and functional parameters. Operating temperature specifications are not provided for these parts. Part 794253-1 carries ROHS3 compliance designation, indicating compliance with the most current RoHS requirements. These parts are suitable for new designs where next-generation series compatibility is acceptable.

All substitute parts are active products with current availability and RoHS compliance certification.

Frequently Asked Questions (FAQ)

Q: Can 172170-1 directly replace 1-172170-2 in existing applications?

A: Yes. Part 172170-1 maintains identical electrical and mechanical specifications, including connector type, position count, pitch, row configuration, mounting type, contact termination, and fastening method. The only difference is housing color (natural versus red). Both parts operate across the same temperature range (-20°C ~ 105°C) and use equivalent insulation materials.

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

A: Both series maintain identical dimensional and functional specifications for the 12-position, 4.14mm pitch plug housing configuration. The MATE-N-LOK II series (794200-1, 794253-1) represents a next-generation variant. Operating temperature data is not provided for MATE-N-LOK II parts. Insulation material specifications differ slightly in documentation format but both series use polyamide and nylon materials.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts carry RoHS compliance certification. Part 794253-1 specifically carries ROHS3 designation, indicating compliance with the most current RoHS requirements.

Q: Does housing color affect electrical or mechanical compatibility?

A: No. Housing color is a cosmetic specification only. The red housing of 1-172170-2 and natural housing of substitute parts do not affect electrical performance, mechanical fit, or functional compatibility.

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

A: MSL rating 1 (Unlimited) indicates that these connector housings have unlimited shelf life and do not require special moisture-controlled storage conditions. This applies to all listed parts.

Q: Can MATE-N-LOK II series parts be used in applications originally designed for MATE-N-LOK series?

A: The MATE-N-LOK II parts (794200-1, 794253-1) maintain identical dimensional and functional specifications. However, operating temperature specifications are not provided for MATE-N-LOK II parts. For applications with specific temperature requirements, parts 172170-1 or 172341-1 are recommended to ensure documented operating temperature performance (-20°C ~ 105°C).

Q: Are contacts included with these connector housings?

A: No. All listed parts are connector housings only. Contacts are not included and must be sourced separately.

Q: What packaging options are available?

A: The main part 1-172170-2 is supplied in unspecified packaging. All substitute parts are available in bulk packaging.
