TE Connectivity 1-1718492-1 Rectangular Connector Plug Housing Equivalents & Substitutes

Part Overview

The TE Connectivity 1-1718492-1 is a 36-position rectangular connector plug housing from the MCP series, designed for panel mount applications with crimp contact termination. This component is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters are required for applications where the original part number is unavailable, inventory constraints exist, or alternative color specifications are acceptable within the same functional specification.

Substitute Part Grouping Explanation

Substitution of rectangular connector plug housings is determined by strict equivalence across electrical and mechanical parameters. The primary substitution criteria for the 1-1718492-1 are:

Critical Matching Parameters:

• Connector type (Plug)
• Number of positions (36)
• Pitch specification (0.157" / 4.00mm)
• Number of rows (4)
• Row spacing (0.165" / 4.20mm)
• Contact type (Tab)
• Mounting type (Panel Mount)
• Contact termination method (Crimp)
• Insulation material (PBT, Glass Filled)
• Operating temperature range (-40°C ~ 120°C)
• Series designation (MCP)
• Compliance certifications (RoHS3, MSL 1)

The substitute part 1-1718492-2 maintains identical electrical and mechanical specifications across all critical parameters. The only variation is the housing color (Purple versus Brown), which does not affect functional compatibility or electrical performance.

Parameter Comparison

Engineering Selection Recommendations

Both the 1-1718492-1 and 1-1718492-2 are Active product status components manufactured by TE Connectivity divisions and maintain full RoHS3 compliance with MSL 1 rating. Selection between these parts is based on the following criteria:

1-1718492-1 (Brown Housing): Select this part number when brown color specification is required for application identification, circuit board assembly color coding standards, or existing system documentation specifies this color variant.

1-1718492-2 (Purple Housing): Select this part number when purple color specification is required for application identification, circuit board assembly color coding standards, or when the brown variant is unavailable. This substitute provides identical electrical and mechanical performance.

Both parts are suitable for applications requiring 36-position rectangular connectors with 4.00mm pitch, panel mount configuration, and crimp termination within the -40°C to 120°C operating range. The choice between variants is determined solely by color requirement and availability, with no functional or performance differentiation.

Frequently Asked Questions (FAQ)

Q: Can 1-1718492-2 be used as a direct replacement for 1-1718492-1?

A: Yes. The 1-1718492-2 is a direct functional equivalent with identical electrical and mechanical specifications. The only difference is housing color (Purple versus Brown). Both parts are MCP series, 36-position, 4.00mm pitch connectors with identical row spacing, contact type, termination method, and operating temperature range.

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

A: No compatibility issues exist from an electrical or mechanical standpoint. Both parts use identical insulation material (PBT, Glass Filled), contact termination (Crimp), and mounting configuration (Panel Mount). The color difference does not affect connector function, mating characteristics, or electrical performance.

Q: What is the significance of the color difference between these parts?

A: The color difference (Brown versus Purple) is a visual identification feature only and does not impact electrical performance, mechanical fit, or thermal characteristics. Color selection is typically driven by application-specific requirements, assembly standards, or inventory availability.

Q: Do both parts require the same contact specifications?

A: Yes. Both 1-1718492-1 and 1-1718492-2 are plug housings designed for tab-type contacts with crimp termination. The note "Contacts Not Included" applies to both parts, indicating that contacts must be sourced separately and are identical for both housing variants.

Q: Are both parts RoHS3 compliant?

A: Yes. Both 1-1718492-1 and 1-1718492-2 are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, suitable for standard storage and handling conditions without special precautions.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the identical temperature range of -40°C to 120°C, suitable for industrial and commercial applications requiring extended thermal performance.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the application does not have specific color requirements or color-coded identification standards. From a functional and performance perspective, the parts are fully interchangeable.
