Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector housings is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type (Receptacle)
• Number of positions (12)
• Pitch specification (0.236" / 6.00mm)
• Number of rows (3)
• Row spacing (0.319" / 8.10mm)
• Mounting type (Panel Mount, Snap-In)
• Contact termination method (Crimp)
• Fastening type (Latch Lock)
• Contact type (Tab)

The substitute part 5-2232356-4 maintains equivalence across all mandatory parameters. Variations in color (Red versus Gray), insulation material composition (PA versus PA6 Glass Filled), and operating temperature range (-55°C to 150°C versus -55°C to 105°C) do not affect mechanical or electrical interchangeability for the connector housing function.

Parameter Comparison

Engineering Selection Recommendations

Both the 6-1971875-4 and 5-2232356-4 are active products manufactured by TE Connectivity AMP Connectors and maintain full compliance with RoHS regulations. The primary part 6-1971875-4 carries RoHS Compliant certification, while the substitute 5-2232356-4 carries ROHS3 Compliant certification, indicating enhanced environmental compliance standards.

Selection between these parts should be based on application-specific requirements:

Select 6-1971875-4 when:

• Operating temperature requirements exceed 105°C and approach the upper limit of 150°C
• Red housing color is specified for circuit board identification or assembly documentation
• Standard polyamide insulation material is required

Select 5-2232356-4 when:

• Operating temperature range of -55°C to 105°C satisfies application requirements
• Gray housing color is acceptable or preferred for assembly purposes
• Glass-filled polyamide material properties are compatible with application demands
• Enhanced ROHS3 compliance certification is required

Both parts share identical mechanical and electrical specifications for the 12-position, 6.00mm pitch rectangular connector housing configuration.

Frequently Asked Questions (FAQ)

Q: Can 5-2232356-4 be used as a direct replacement for 6-1971875-4 in all applications?

A: The 5-2232356-4 functions as a direct mechanical and electrical substitute for the 6-1971875-4 in applications where the operating temperature does not exceed 105°C. Both parts maintain identical pitch, position count, row configuration, mounting type, and contact termination specifications. Applications requiring sustained operation above 105°C must use the 6-1971875-4.

Q: What is the significance of the different insulation materials between these parts?

A: The 6-1971875-4 uses standard polyamide (PA) nylon insulation, while the 5-2232356-4 uses glass-filled polyamide (PA6) nylon 6. Glass-filled material provides enhanced mechanical strength and dimensional stability. Both materials are suitable for the connector housing function and do not affect electrical interchangeability.

Q: Does the color difference between Red (6-1971875-4) and Gray (5-2232356-4) affect functionality?

A: Color is a visual identification feature only and does not affect electrical or mechanical performance. Selection between red and gray housings should be based on assembly documentation requirements, circuit board color coding standards, or visual identification protocols specific to the application.

Q: Are both parts equally available in inventory?

A: The 5-2232356-4 has higher current inventory availability with 1007 units in stock compared to 787 units for the 6-1971875-4. Inventory levels may change based on production and distribution schedules.

Q: What does the difference in RoHS certification levels mean?

A: Both parts are RoHS compliant. The 6-1971875-4 carries standard RoHS Compliant certification, while the 5-2232356-4 carries ROHS3 Compliant certification, indicating compliance with the most recent RoHS directive requirements. Both certifications satisfy current regulatory requirements for hazardous substance restrictions.

Q: Can contacts from one part number be used with housings from the other?

A: Both part numbers specify that contacts are not included with the housing. Contact compatibility is determined by the contact part number and specifications, not by the housing color or insulation material. Verify contact part numbers separately for interchangeability.

Q: What is the significance of Moisture Sensitivity Level 1 (Unlimited)?

A: MSL 1 (Unlimited) indicates that the component has no moisture sensitivity restrictions and does not require special handling, storage, or baking procedures prior to assembly. Both parts share this specification.
