TE Connectivity Deutsch Connectors 3-2112231-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity Deutsch Connectors 3-2112231-3 is a 46-position rectangular connector receptacle housing designed for applications requiring sealed, high-reliability connections. This component is classified as a receptacle housing with female socket contacts, featuring a 4.00mm pitch and three-row configuration. The part is currently Active in product status and is manufactured with IP67-rated sealing for environmental protection.

Substitute parts are identified when equivalent rectangular connector housings share identical electrical and mechanical specifications, allowing direct replacement in applications where connector color or specific inventory availability differs. The substitute relationship is strictly limited to housings with matching position count, pitch, row configuration, and performance ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3-2112231-3 rectangular connector receptacle housing are identified based on strict parametric equivalence. The following parameters must remain identical for a part to qualify as a direct substitute:

• Number of Positions: 46
• Pitch: 0.157" (4.00mm)
• Number of Rows: 3
• Row Spacing: 0.177" (4.50mm)
• Connector Type: Receptacle
• Contact Type: Female Socket
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Insulation Material: Polybutylene Terephthalate (PBT), Glass Filled
• Operating Temperature Range: -40°C ~ 120°C
• Features: IP67, Right Angle Cable Exit, Sealed, Strain Relief, Terminal Position Lock (TPA)
• Series: MCP 1.5K
• RoHS Status: ROHS3 Compliant

The only parameter that may differ between the main part and its substitute is the housing color. The 3-2112231-3 features a blue housing, while substitute parts may be available in alternative colors such as gray. This color variation does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 3-2112231-3 and 3-2112231-2 are Active products manufactured by TE Connectivity Deutsch Connectors within the MCP 1.5K series. Both parts maintain ROHS3 compliance and carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

The parts are electrically and mechanically equivalent, with identical specifications for position count, pitch, row configuration, mounting type, contact termination, operating temperature range, and feature set. The sole distinction is the housing color: the 3-2112231-3 features a blue housing, while the 3-2112231-2 features a gray housing.

Selection between these parts should be based on application-specific requirements regarding connector color identification or visual marking standards. Both parts are suitable for sealed, high-reliability applications requiring IP67 environmental protection and terminal position locking.

Frequently Asked Questions (FAQ)

Q: Can the 3-2112231-2 be used as a direct replacement for the 3-2112231-3?

A: Yes. The 3-2112231-2 is a parametric equivalent with identical electrical and mechanical specifications. The only difference is the housing color (gray versus blue). Both parts share the same position count (46), pitch (4.00mm), row configuration (3 rows), mounting type, contact termination method, and performance ratings.

Q: Are there any compatibility issues when substituting between these parts?

A: No compatibility issues exist from an electrical or mechanical standpoint. Both parts are receptacle housings with female socket contacts, identical row spacing, and matching feature sets including IP67 sealing, right angle cable exit, strain relief, and terminal position locking.

Q: Does the color difference affect performance or reliability?

A: No. The color difference is a cosmetic variation only. Both parts use the same insulation material (PBT, glass filled) and maintain identical operating temperature ranges (-40°C ~ 120°C) and environmental protection ratings (IP67).

Q: Are contacts included with these connector housings?

A: No. Both the 3-2112231-3 and 3-2112231-2 are housings only. Contacts are not included and must be sourced separately. The crimp termination type requires compatible female socket contacts for assembly.

Q: What is the significance of the MCP 1.5K series designation?

A: The MCP 1.5K series is the product line designation for these rectangular connectors from TE Connectivity Deutsch Connectors. Both substitute parts belong to this same series, ensuring design and performance consistency.

Q: Are both parts RoHS compliant?

A: Yes. Both the 3-2112231-3 and 3-2112231-2 are ROHS3 compliant, meeting current environmental and hazardous substance restrictions for electronic components.

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

A: MSL 1 (Unlimited) indicates that these parts have no moisture sensitivity restrictions. They can be stored and handled without special moisture control measures, simplifying inventory management and logistics.
