Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2-1703818-1 are identified through parametric matching within the MCP 2.8 series. The substitution logic is based on the following critical parameters that determine functional interchangeability:

Matching Parameters (Required for Substitution):

• Connector Type: Plug
• Number of Positions: 4
• Pitch: 0.236" (6.00mm)
• Number of Rows: 2
• Row Spacing: 0.236" (6.00mm)
• Contact Type: Tab
• Contact Termination: Crimp
• Mounting Type: Panel Mount
• Fastening Type: Slide-On
• Operating Temperature Range: -40°C to 140°C
• Insulation Material: Polybutylene Terephthalate (PBT), Glass Filled
• Features: Sealed
• Series: Heavy Duty Sealed Connector Series, MCP 2.8

Variable Parameters (Non-Critical for Substitution):

• Color (Gray vs. Black)
• Inventory availability

The substitute part 1-1703818-1 maintains identical electrical and mechanical specifications, with the only distinction being housing color and current stock levels.

Parameter Comparison

Engineering Selection Recommendations

Both the 2-1703818-1 and 1-1703818-1 are Active product status components with identical compliance certifications. Selection between these parts is based on the following engineering criteria:

Compliance & Regulatory: Both parts maintain ROHS3 compliance, EAR99 export classification, and unlimited moisture sensitivity rating (MSL 1). No compliance-based restrictions apply to either part.

Functional Equivalence: The parts are functionally equivalent across all electrical and mechanical parameters. The connector housing geometry, contact interface, sealing characteristics, and operating temperature range are identical.

Differentiation Factor: The primary distinction is housing color. The 2-1703818-1 features gray housing, while the 1-1703818-1 features black housing. Color selection should be based on application requirements, PCB assembly standards, or system identification protocols.

Inventory Consideration: The 1-1703818-1 (black) currently maintains higher inventory availability (3107 pcs) compared to the 2-1703818-1 (gray, 1207 pcs). For applications without color-specific requirements, the black variant offers improved lead time assurance.

Frequently Asked Questions (FAQ)

Q: Are the 2-1703818-1 and 1-1703818-1 mechanically interchangeable?

A: Yes. Both parts share identical mechanical specifications including pitch (0.236"/6.00mm), row configuration (2 rows), contact type (Tab), and mounting interface (Panel Mount, Slide-On fastening). They are mechanically interchangeable.

Q: Are the 2-1703818-1 and 1-1703818-1 electrically interchangeable?

A: Yes. Both parts maintain identical electrical specifications including 4-position capacity, crimp contact termination, operating temperature range (-40°C to 140°C), and sealed connector features. They are electrically interchangeable.

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

A: The housing color. The 2-1703818-1 is gray, while the 1-1703818-1 is black. All other specifications are identical.

Q: Can I substitute the gray housing (2-1703818-1) with the black housing (1-1703818-1) in my assembly?

A: Substitution is permissible from an engineering standpoint if color is not a functional or aesthetic requirement. Verify application specifications for any color-dependent requirements before substitution.

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

A: Yes. Both the 2-1703818-1 and 1-1703818-1 are housing-only components. Contacts are not included and must be sourced separately as crimp-type tab contacts compatible with the MCP 2.8 series.

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

A: Both parts operate across -40°C to 140°C, suitable for industrial and automotive applications requiring sealed connector performance across extended temperature ranges.

Q: Are both parts RoHS compliant?

A: Yes. Both the 2-1703818-1 and 1-1703818-1 are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: What is the pitch specification for these connectors?

A: Both parts feature 0.236" (6.00mm) pitch with 2-row configuration and 0.236" (6.00mm) row spacing, maintaining the MCP 2.8 series standard.
