TE Connectivity 4-1703843-1 Rectangular Connector Plug Housing Equivalent & Substitute Parts

Part Overview

The TE Connectivity 4-1703843-1 is a 3-position rectangular connector plug housing from the Heavy Duty Sealed Connector Series (MCP 1.5K). This component serves as the housing assembly for sealed connector applications requiring panel mount installation with crimp contact termination. The part is Active in product status with 1484 units currently in stock inventory.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector specification, allowing for direct functional replacement in applications where the primary part becomes unavailable or when alternative configurations are required for specific assembly requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector plug housings is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Connector type (Plug)
• Number of positions (3)
• Contact type (Tab)
• Pitch specification (0.157" / 4.00mm)
• Number of rows (1)

Mechanical Parameters:

• Mounting type (Panel Mount)
• Contact termination method (Crimp)
• Fastening type (Slide-On)
• Insulation material composition (PBT, Glass Filled)
• Operating temperature range (-40°C ~ 140°C)
• Features (Mounting Flange, Sealed)

Compliance Parameters:

• Series designation (Heavy Duty Sealed Connector Series, MCP 1.5K)
• RoHS3 compliance status
• Moisture Sensitivity Level (MSL 1)

Substitute parts maintain identical specifications across all listed parameters. Variations in color designation do not affect functional compatibility or electrical performance.

Parameter Comparison

Engineering Selection Recommendations

Both the 4-1703843-1 and 1-1703843-1 are Active products manufactured by TE Connectivity with full ROHS3 compliance and MSL 1 rating. Selection between these parts is based on the following criteria:

Primary Selection Criteria:

• Color requirement: The 4-1703843-1 features blue housing; the 1-1703843-1 features black housing. Color selection is determined by application-specific assembly or identification requirements.
• Inventory availability: The 4-1703843-1 maintains 1484 units in stock; the 1-1703843-1 maintains 1360 units in stock.

Compliance Status: Both parts maintain identical compliance certifications including ROHS3 compliance and MSL 1 rating, confirming suitability for equivalent applications without additional qualification requirements.

Functional Equivalence: All electrical and mechanical parameters are identical across both parts, including connector type, position count, pitch specification, mounting configuration, termination method, insulation material, and operating temperature range. These parts are direct functional equivalents.

Frequently Asked Questions (FAQ)

Q: Can the 1-1703843-1 (black) be used as a direct replacement for the 4-1703843-1 (blue)?

A: Yes. Both parts are functionally equivalent across all electrical and mechanical parameters. The only difference is the housing color. Selection depends on whether color coding is required for your application.

Q: Are the contact specifications identical between these two parts?

A: Both parts use identical tab-type contacts with crimp termination and 0.157" (4.00mm) pitch spacing. Contacts are not included with either housing and must be sourced separately.

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

A: Both the 4-1703843-1 and 1-1703843-1 operate across the range of -40°C to 140°C.

Q: Are both parts RoHS compliant?

A: Yes. Both parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the mounting configuration for these connectors?

A: Both parts are panel mount connectors with slide-on fastening type and include mounting flange features for sealed applications.

Q: Do these parts include contacts?

A: No. Both the 4-1703843-1 and 1-1703843-1 are housing assemblies only. Contacts must be sourced and crimped separately.

Q: What is the pitch specification for the 3-position configuration?

A: The pitch specification is 0.157 inches (4.00mm) for both parts, defining the center-to-center spacing between the three contact positions.

Q: Are there any differences in the insulation material between these parts?

A: No. Both parts use identical Polybutylene Terephthalate (PBT) glass-filled insulation material.
