TE Connectivity AMP Connectors 4-1971875-4 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 4-1971875-4 is a 12-position rectangular connector receptacle housing designed for panel mount and snap-in applications. This connector operates across a temperature range of -55°C to 105°C and features a 6.00mm pitch configuration with three rows of contacts. The part is manufactured from polybutylene terephthalate (PBT) glass-filled insulation material and utilizes crimp termination with latch lock fastening. The product maintains active status and is RoHS compliant. Equivalent substitute parts may be required due to inventory availability, supply chain considerations, or specific application requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 4-1971875-4 is based on strict equivalence of the following critical parameters:

• Connector Type: Receptacle housing only
• Position Count: 12 positions
• Pitch Specification: 0.236" (6.00mm)
• Row Configuration: 3 rows with 0.319" (8.10mm) row spacing
• Mounting Interface: Panel mount with snap-in capability
• Contact Interface: Tab contact type with crimp termination
• Fastening Mechanism: Latch lock system
• Operating Temperature: -55°C to 105°C range
• Moisture Sensitivity: MSL 1 (Unlimited)

The substitute part 5-2232356-4 maintains all critical electrical and mechanical parameters required for direct substitution. Variations in insulation material composition and color do not affect functional compatibility when these core parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

Both the 4-1971875-4 and 5-2232356-4 maintain active product status with full regulatory compliance. The 4-1971875-4 is RoHS compliant, while the 5-2232356-4 carries ROHS3 compliance, indicating adherence to current regulatory standards. Both parts are manufactured by TE Connectivity AMP Connectors and share identical electrical and mechanical specifications across all critical parameters.

Selection between these parts should be based on:

• Inventory Availability: The 5-2232356-4 currently maintains higher stock levels (1007 pcs) compared to the 4-1971875-4 (856 pcs)
• Regulatory Requirements: Applications requiring ROHS3 compliance should specify the 5-2232356-4
• Material Specification: Applications with specific insulation material requirements should reference the material composition differences
• Visual Identification: Color differentiation (yellow versus gray) may be relevant for assembly or maintenance procedures

Frequently Asked Questions (FAQ)

Q: Can the 5-2232356-4 directly replace the 4-1971875-4 in existing applications?

A: Yes. Both parts maintain identical specifications for connector type, position count, pitch, row configuration, mounting interface, contact type, termination method, fastening mechanism, and operating temperature range. The parts are mechanically and electrically interchangeable.

Q: What is the significance of the different insulation materials?

A: The 4-1971875-4 uses polybutylene terephthalate (PBT) glass-filled material, while the 5-2232356-4 uses polyamide (PA6) nylon 6 glass-filled material. Both materials are glass-filled and operate across the same temperature range. Material selection may depend on specific application requirements for chemical resistance, mechanical properties, or environmental exposure.

Q: Are there compliance differences between these parts?

A: The 4-1971875-4 is RoHS compliant, and the 5-2232356-4 is ROHS3 compliant. Both meet current regulatory standards. ROHS3 represents the current regulatory designation. Applications requiring specific compliance certifications should reference the appropriate part number.

Q: Does the color difference affect functionality?

A: No. Color is a visual identifier only and does not affect electrical or mechanical performance. Color selection may be relevant for assembly documentation, maintenance procedures, or internal identification systems.

Q: What does MSL 1 (Unlimited) mean for these connectors?

A: Moisture Sensitivity Level 1 indicates the lowest moisture sensitivity classification. These parts have unlimited shelf life under normal storage conditions and do not require special moisture-controlled storage or handling procedures.

Q: Are contacts included with these housing parts?

A: No. Both the 4-1971875-4 and 5-2232356-4 are receptacle housings only. Contacts must be sourced separately and are not included with these parts.

Q: Can these parts be used interchangeably in the same assembly?

A: Yes. Both parts share identical mechanical interfaces, mounting specifications, and electrical characteristics. They can be used interchangeably within the same assembly without modification to mating components or installation procedures.
