Equivalent & Substitute Parts: TE Connectivity 3-1418448-2

Part Overview

The TE Connectivity 3-1418448-2 is a 2-position rectangular connector receptacle housing from the Heavy Duty Sealed Connector Series (MCP 1.5K). This component serves as the female socket housing in sealed connector applications requiring 0.315" (8.00mm) pitch spacing. The part is actively manufactured and maintained in production inventory. Substitute parts are identified when equivalent electrical and mechanical parameters are required but alternative configurations—such as different housing colors—are acceptable within application constraints.

Substitute Part Grouping Explanation

Substitution of rectangular connector housings within the TE Connectivity Heavy Duty Sealed Connector Series (MCP 1.5K) is determined by strict equivalence across the following critical parameters:

Electrical and Mechanical Equivalence Criteria:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (2)
• Pitch spacing (0.315" / 8.00mm)
• Number of rows (1)
• Mounting type (Free Hanging / In-Line)
• Contact termination method (Crimp)
• Fastening type (Slide-On)
• Insulation material (PBT, Glass Filled)
• Operating temperature range (-40°C to 140°C)
• Sealed feature requirement

Variable Parameters Permitting Substitution:

• Housing color (Green or Black)

The substitute part 1-1418448-2 maintains identical electrical and mechanical specifications to the main part 3-1418448-2. The only difference is the housing color, which changes from Green to Black. Both parts share the same base product number (1418448) and series designation, confirming their functional interchangeability within the MCP 1.5K connector family.

Parameter Comparison

Engineering Selection Recommendations

Both the main part (3-1418448-2) and substitute part (1-1418448-2) are active products manufactured by TE Connectivity and maintain full ROHS3 compliance. Selection between these parts is based on application-specific requirements:

Select 3-1418448-2 (Green Housing) when:

• Application design specifications or color-coding standards require green housing identification
• Existing inventory or assembly documentation specifies green connector housings

Select 1-1418448-2 (Black Housing) when:

• Application design specifications or color-coding standards require black housing identification
• Green housing availability is constrained
• Existing inventory or assembly documentation specifies black connector housings

Both parts carry identical electrical performance, mechanical compatibility, and regulatory compliance certifications. The choice between them is determined solely by application color requirements and inventory availability. No performance degradation or functional limitation occurs when substituting between these two part numbers within the MCP 1.5K series.

Frequently Asked Questions (FAQ)

Q: Are the 3-1418448-2 and 1-1418448-2 electrically interchangeable?

A: Yes. Both parts are female socket receptacle housings with identical electrical specifications, including 2-position configuration, 0.315" (8.00mm) pitch, crimp termination, and sealed design. They operate across the same temperature range (-40°C to 140°C) and carry identical RoHS3 compliance.

Q: What is the only difference between these two parts?

A: The housing color. The 3-1418448-2 features a green housing, while the 1-1418448-2 features a black housing. All other mechanical, electrical, and performance parameters are identical.

Q: Can I use the black housing (1-1418448-2) in place of the green housing (3-1418448-2) in my assembly?

A: Substitution is permissible only if application design specifications, color-coding requirements, or assembly documentation do not mandate green housing. If color identification is functionally required for the application, substitution is not appropriate.

Q: Do these parts require contacts to be purchased separately?

A: Yes. Both the 3-1418448-2 and 1-1418448-2 are housings only. Contacts are not included and must be ordered separately as specified in the product documentation.

Q: Are both parts currently in production?

A: Yes. Both parts maintain Active product status with TE Connectivity and are available in production inventory.

Q: What is the base product number for these connectors?

A: The base product number is 1418448. Both the 3-1418448-2 and 1-1418448-2 derive from this base number, indicating they belong to the same connector family within the Heavy Duty Sealed Connector Series (MCP 1.5K).

Q: What mounting configuration do these housings support?

A: Both parts support Free Hanging (In-Line) mounting with slide-on fastening. They are designed for crimp-terminated contacts and are suitable for applications requiring sealed connector performance.
