Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector housings in the Mini-Universal MATE-N-LOK series is determined by the following critical parameters:

Electrical Compatibility Parameters:

Connector type (Receptacle)
Number of positions (6)
Pitch (0.163" / 4.14mm)
Number of rows (2)
Row spacing (0.163" / 4.14mm)
Contact termination method (Crimp)
Fastening type (Locking Ramp)

Mechanical Compatibility Parameters:

Mounting type (Panel Mount, Snap-In)
Insulation material (Polyamide/Nylon variants)
Operating temperature range (minimum -20°C, maximum 105°C)

Regulatory Compliance Parameters:

RoHS compliance status

Engineering Selection Recommendations

All five substitute parts (1-172160-2, 1-172160-9, 172160-1, 172331-1, and 794940-1) are functionally equivalent to the obsolete 1-172331-2 and maintain full electrical and mechanical compatibility within the Mini-Universal MATE-N-LOK series.

Primary Selection Criteria:

For Active Product Status: Parts 1-172160-2, 1-172160-9, 172160-1, 172331-1, and 794940-1 are all classified as Active, providing long-term availability and supply chain continuity compared to the obsolete main part.

For Extended Temperature Range: Parts 172160-1, 172331-1, and 794940-1 support an operating temperature range of -55°C ~ 105°C, compared to -20°C ~ 105°C for the main part and 1-172160-2. Selection of these parts is appropriate for applications requiring lower temperature operation.

For RoHS3 Compliance: Part 1-172160-9 carries ROHS3 Compliant certification, providing enhanced regulatory alignment for applications with strict RoHS3 requirements.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for 1-172331-2?

A: All five substitute parts are electrically and mechanically equivalent to 1-172331-2. They share identical connector type, position count, pitch, row configuration, mounting type, contact termination, and fastening specifications. Direct substitution is supported within the Mini-Universal MATE-N-LOK series.

Q: What is the difference between the substitute parts?

A: The substitute parts differ in three non-functional aspects: color (Red, Black, or Natural), operating temperature range (-20°C ~ 105°C or -55°C ~ 105°C), and product status (all are Active). All parts maintain identical electrical and mechanical specifications.

Q: Does color affect electrical performance?

A: No. Color is a cosmetic designation and does not affect electrical performance, impedance, or mechanical fit. Color selection is based on application requirements or design specifications only.

Q: Why do some parts support -55°C minimum temperature while others support -20°C?

A: Operating temperature range is a material and design specification. Parts 172160-1, 172331-1, and 794940-1 are rated for -55°C ~ 105°C operation, while 1-172331-2 and 1-172160-2 are rated for -20°C ~ 105°C. Selection depends on the application's minimum operating temperature requirement.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts carry RoHS compliance certification. Part 1-172160-9 specifically carries ROHS3 Compliant certification, providing enhanced regulatory alignment.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 (Unlimited) indicates that the component has no moisture sensitivity restrictions. These parts can be stored and handled without special moisture control measures.

Q: Can I mix substitute parts in the same assembly?

A: Yes. All substitute parts are mechanically and electrically interchangeable within the same assembly. However, color consistency may be a design consideration depending on application requirements.

Q: Which substitute part should I select for new designs?

A: For new designs, select from the Active parts based on specific requirements: 1-172160-2 for Red color, 1-172160-9 for Black color with ROHS3 compliance, or 172160-1, 172331-1, and 794940-1 for Natural color with extended temperature range (-55°C ~ 105°C). Part 794940-1 offers the highest inventory availability.

Q: Are contacts included with these connector housings?

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

Q: What is the difference between base product numbers 172331 and 172160?

A: Base product numbers identify different product lines within the Mini-Universal MATE-N-LOK series. Both 172331 and 172160 series parts are functionally equivalent for this 6-position, 4.14mm pitch configuration and are interchangeable.
