Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 794253-1 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Equivalence Criteria:

• 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: Crimp
• Fastening type: Latch Lock
• Color: Natural
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts meet these core electrical and mechanical parameters. Variations exist in series designation (Mini-Universal MATE-N-LOK versus Mini-Universal MATE-N-LOK II), insulation material composition, operating temperature specifications, and RoHS compliance status. These variations do not affect the fundamental substitution relationship for applications requiring a 12-position rectangular connector plug housing with 4.14mm pitch and latch lock fastening.

Parameter Comparison

Engineering Selection Recommendations

All four part numbers (794253-1, 172170-1, 172341-1, and 794200-1) are active products from TE Connectivity AMP Connectors and meet the core mechanical and electrical requirements for 12-position rectangular connector plug housings with 4.14mm pitch and latch lock fastening.

Compliance Considerations:

The 794253-1 carries ROHS3 compliance status. The substitute parts 172170-1, 172341-1, and 794200-1 carry RoHS compliance status. All parts maintain MSL 1 (Unlimited) moisture sensitivity level, indicating no special moisture handling requirements during storage or assembly.

Series Compatibility:

The 794253-1 and 794200-1 belong to the Mini-Universal MATE-N-LOK II series. The 172170-1 and 172341-1 belong to the Mini-Universal MATE-N-LOK series. Both series are compatible for applications requiring 12-position plug housings with identical pitch and row spacing specifications.

Material and Temperature Specifications:

The 794253-1 and 794200-1 specify Polyamide (PA) and Nylon insulation material without defined operating temperature ranges. The 172170-1 and 172341-1 specify Polyamide (PA66) and Nylon 6/6 insulation material with operating temperature range of -20°C to 105°C. Selection between these options depends on application-specific temperature requirements and material compatibility needs.

Inventory Availability:

Part 172170-1 offers the highest inventory availability at 7767 pieces, followed by 172341-1 at 3852 pieces, 794200-1 at 1083 pieces, and 794253-1 at 814 pieces. Inventory levels should be considered when planning component procurement and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can 172170-1 be used as a direct replacement for 794253-1?

A: Yes. Both parts are 12-position rectangular connector plug housings with 0.163" (4.14mm) pitch, 3-row configuration, free-hanging in-line mounting, crimp termination, and latch lock fastening. The primary differences are series designation (MATE-N-LOK versus MATE-N-LOK II), insulation material composition (PA66 Nylon 6/6 versus PA Nylon), and defined operating temperature range (-20°C to 105°C versus unspecified). These differences do not prevent functional substitution in applications where the mechanical and electrical interface requirements are met.

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

A: Both series are Mini-Universal connector families from TE Connectivity. The 794253-1 and 794200-1 are designated as MATE-N-LOK II series, while 172170-1 and 172341-1 are designated as MATE-N-LOK series. All four parts meet identical specifications for 12-position plug housings with 4.14mm pitch and latch lock fastening. Series designation reflects product line organization but does not affect mechanical or electrical compatibility for the specified connector configuration.

Q: Are there operating temperature differences between substitute parts?

A: The 172170-1 and 172341-1 specify an operating temperature range of -20°C to 105°C. The 794253-1 and 794200-1 do not specify operating temperature ranges in the provided data. Applications requiring defined temperature performance specifications should reference the 172170-1 or 172341-1 parts or obtain complete technical documentation for the 794253-1 and 794200-1 from TE Connectivity.

Q: What is the significance of the insulation material differences?

A: The 794253-1 and 794200-1 use Polyamide (PA) and Nylon insulation material. The 172170-1 and 172341-1 use Polyamide (PA66) and Nylon 6/6 insulation material. PA66 (Nylon 6/6) is a specific polyamide formulation with defined material properties. Both material types are suitable for rectangular connector housings. Material selection should be based on application-specific requirements for chemical resistance, mechanical strength, and thermal performance.

Q: Do all substitute parts have the same RoHS compliance status?

A: The 794253-1 is ROHS3 compliant. The 172170-1, 172341-1, and 794200-1 are RoHS compliant. ROHS3 represents a more recent compliance standard than RoHS. Applications requiring ROHS3 compliance should specify the 794253-1 or verify compliance requirements with the end-use application specifications.

Q: Are contacts included with these connector housings?

A: No. All four part numbers (794253-1, 172170-1, 172341-1, and 794200-1) are connector housings only. Contacts are not included and must be sourced separately. Crimp contacts compatible with 4.14mm pitch rectangular connectors must be specified and procured as separate components.

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

A: MSL 1 (Unlimited) indicates that these connector housings have unlimited shelf life and do not require special moisture-controlled storage conditions. This classification applies to plastic connector housings and indicates minimal moisture sensitivity during manufacturing, storage, and assembly processes.
