TE Connectivity 4-1418448-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 4-1418448-1 is a 3-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 4.00mm pitch spacing. The part is actively manufactured and maintained in production inventory.

Substitute parts become necessary when specific color requirements, regional supplier preferences, or inventory availability constraints affect procurement. All equivalent parts listed maintain identical electrical and mechanical specifications while differing only in housing color or manufacturer designation within the TE Connectivity product family.

Key Parameters

Substitute Part Grouping Explanation

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

Critical Substitution Parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (3)
• Pitch specification (0.157" / 4.00mm)
• 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
• Series designation (Heavy Duty Sealed Connector Series, MCP 1.5K)

Non-Critical Substitution Parameters:

• Housing color (Blue, Gray, Black)
• Manufacturer designation within TE Connectivity product family

All substitute parts listed maintain 100% equivalence across critical parameters. Variations in housing color do not affect electrical performance, mechanical fit, or thermal characteristics. The base product number 1418448 remains constant across all equivalent variants.

Parameter Comparison

Engineering Selection Recommendations

All three parts listed—4-1418448-1, 2-1418448-1, and 1-1418448-1—are active production components from TE Connectivity with full regulatory compliance. Selection between these equivalents should be based on the following factors:

Compliance Status: The main part (4-1418448-1) and substitute 1-1418448-1 carry ROHS3 Compliant certification. Substitute 2-1418448-1 carries RoHS Compliant certification. Both certifications satisfy current regulatory requirements for the 8536.69.8000 HTSUS classification.

Inventory Availability: Current stock levels are 1426 units (4-1418448-1), 1900 units (2-1418448-1), and 1032 units (1-1418448-1). Selection may be influenced by procurement lead time requirements and supply chain constraints.

Manufacturer Designation: Parts 4-1418448-1 and 2-1418448-1 are designated under TE Connectivity AMP Connectors. Part 1-1418448-1 is designated under TE Connectivity Deutsch Connectors. Both divisions operate under the unified TE Connectivity organization with equivalent quality standards.

Housing Color: The only functional difference among these parts is housing color (Blue, Gray, or Black). Color selection does not affect electrical performance, mechanical compatibility, or thermal characteristics. Color choice should be based on application-specific requirements, such as visual identification, environmental conditions, or assembly documentation standards.

Frequently Asked Questions (FAQ)

Q: Can 2-1418448-1 (Gray) be used as a direct replacement for 4-1418448-1 (Blue)?

A: Yes. Both parts are parametric equivalents with identical electrical and mechanical specifications. The only difference is housing color. Direct substitution is valid from an engineering standpoint.

Q: Are there any compatibility issues between the AMP Connectors and Deutsch Connectors variants?

A: No. Both 4-1418448-1 and 1-1418448-1 are manufactured by TE Connectivity divisions and maintain identical specifications for connector type, contact configuration, pitch, mounting, and termination. They are fully compatible within the same application.

Q: Does the housing color affect the connector's sealing performance?

A: No. The sealed feature is a material and design characteristic of the PBT glass-filled insulation material and connector geometry. Housing color does not impact sealing performance across any of the three variants.

Q: What is the significance of the base product number 1418448?

A: The base product number 1418448 identifies the core connector housing design. The prefix digits (1-, 2-, or 4-) indicate color variants and manufacturer designation within the TE Connectivity product family. All variants share the same base design and specifications.

Q: Are all three parts RoHS compliant?

A: Yes. The main part (4-1418448-1) and 1-1418448-1 carry ROHS3 Compliant certification. Part 2-1418448-1 carries RoHS Compliant certification. Both compliance levels satisfy current regulatory requirements for this product category.

Q: Can these connectors be used in applications requiring temperatures below -40°C or above 140°C?

A: No. The operating temperature range for all three variants is -40°C to 140°C. Applications requiring operation outside this range require alternative connector designs.

Q: Are contacts included with these housing parts?

A: No. All three variants are housings only. Contacts must be procured separately and installed via the crimp termination method specified for this series.

Q: What is the pitch specification and why is it important?

A: The pitch is 0.157" (4.00mm), which specifies the center-to-center distance between contact positions. This dimension is critical for mechanical compatibility with mating connectors and contact insertion. All three variants maintain identical pitch specifications.
