TE Connectivity Deutsch Connectors 3-2112231-1 Rectangular Connector Housing

Part Overview

The TE Connectivity Deutsch Connectors 3-2112231-1 is a 46-position rectangular connector receptacle housing designed for industrial and commercial applications requiring sealed, high-reliability connections. This component is a receptacle housing with female socket contacts, featuring a 4.00mm pitch configuration across three rows. The part is classified as Active product status and is ROHS3 compliant.

Equivalent and substitute parts are necessary when specific color variants are required for application-specific identification, inventory management, or when primary stock availability is limited. All substitute parts maintain identical electrical and mechanical specifications while differing only in housing color.

Substitute Part Grouping Explanation

Substitute parts for the 3-2112231-1 rectangular connector housing are determined by strict equivalence across all electrical and mechanical parameters. The substitution logic is based on the following criteria:

Substitution-Determining Parameters:

• 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 to 120°C
• Series: MCP 1.5K
• Features: IP67, Right Angle Cable Exit, Sealed, Strain Relief, Terminal Position Lock (TPA)

Variable Parameter (Non-Substitution Determining):

• Housing Color: Black, Gray, or Blue

All substitute parts maintain identical form, fit, and function characteristics. The only difference among the main part and its substitutes is the housing color, which serves as a visual identification marker and does not affect electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

All three parts—3-2112231-1, 3-2112231-2, and 3-2112231-3—are Active product status and ROHS3 compliant, meeting current regulatory requirements for industrial and commercial applications. Selection between these parts should be based on application-specific requirements for housing color identification and current inventory availability.

The 3-2112231-1 (Black) variant maintains the highest inventory level at 1134 pieces, followed by 3-2112231-2 (Gray) at 1102 pieces, and 3-2112231-3 (Blue) at 921 pieces. All parts share identical electrical performance characteristics, mechanical dimensions, and environmental ratings.

For applications requiring color-coded connector identification systems, the appropriate variant should be selected based on the established color scheme. For general applications without color-coding requirements, any of the three variants provides equivalent functionality and performance.

Frequently Asked Questions (FAQ)

Q: Are the 3-2112231-1, 3-2112231-2, and 3-2112231-3 connectors fully interchangeable?

A: Yes. These parts are fully interchangeable from an electrical and mechanical standpoint. All three maintain identical contact configurations, pitch spacing, row arrangement, mounting characteristics, and environmental ratings. The only difference is housing color.

Q: Does housing color affect electrical performance or signal integrity?

A: No. Housing color is a visual identification feature only and does not impact electrical performance, signal integrity, or mechanical function.

Q: Can I use these connectors in applications requiring color-coded identification?

A: Yes. The three color variants—Black, Gray, and Blue—can be used to implement color-coded connector identification systems within applications or installations.

Q: What is the pitch specification for these rectangular connectors?

A: The pitch is 0.157 inches (4.00mm), with row spacing of 0.177 inches (4.50mm) across the three-row configuration.

Q: Are these connectors sealed and suitable for harsh environments?

A: Yes. All three variants feature IP67 rating, sealed construction, strain relief, and Terminal Position Lock (TPA) features, making them suitable for sealed, harsh environment applications.

Q: What is the operating temperature range for these connectors?

A: The operating temperature range is -40°C to 120°C for all three variants.

Q: Do these connector housings include contacts?

A: No. These are housing-only components. Contacts are not included and must be sourced separately.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: The MSL is 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are these parts RoHS compliant?

A: Yes. All three variants are ROHS3 compliant.
