Equivalent & Substitute Parts for 4282-3-18-D Rectangular Connector Plug Housing

Part Overview

The CNC Tech 4282-3-18-D is an 18-position rectangular connector plug housing with 4.20mm pitch, designed for free-hanging in-line applications. This connector housing accommodates male pin contacts through crimp termination and features a locking ramp fastening mechanism. The part is currently active in production with 901 units in stock.

Substitute parts are necessary when the original manufacturer discontinues production, when alternative sourcing improves lead times or cost efficiency, or when design requirements allow for compatible connector families from different manufacturers. All substitute parts listed maintain electrical and mechanical compatibility through identical or equivalent parameter specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the 4282-3-18-D is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

Connector Type: Plug
Contact Type: Male Pin
Number of Positions: 18
Pitch: 0.165" (4.20mm)
Number of Rows: 2
Row Spacing: 0.165" (4.20mm)
Mounting Type: Free Hanging (In-Line)
Contact Termination: Crimp
Fastening Type: Locking Ramp
Moisture Sensitivity Level: 1 (Unlimited)

All five substitute parts meet these mandatory parameters. Variations in color (White vs. Natural), insulation material composition (PA66 vs. PA), and product status do not affect functional interchangeability in applications where the connector housing performs its specified role.

Engineering Selection Recommendations

Active Status Parts (Recommended for New Designs):

The following substitute parts carry Active product status and are suitable for new design implementations:

0039013183 (Molex Mini-Fit Jr 5559): Active status with highest inventory availability (17213 units). ROHS3 compliant. Suitable for applications where connector color is not a design constraint.
1-1586000-8 (TE Connectivity VAL-U-LOK): Active status with specified operating temperature range (-40°C ~ 105°C). RoHS compliant. Inventory of 1211 units supports production requirements.
1-1969604-8 (TE Connectivity VAL-U-LOK): Active status with ROHS3 compliance and full operating temperature specification. Inventory of 889 units available.
1-1969612-8 (TE Connectivity VAL-U-LOK): Active status with ROHS3 compliance and full operating temperature specification. Highest TE Connectivity inventory at 1629 units.

Obsolete Status Part (Not Recommended for New Designs):

1-1969598-8 (TE Connectivity VAL-U-LOK): Marked as Obsolete. While functionally equivalent and currently in stock (1257 units), this part should not be selected for new product designs due to discontinued production status.

Compliance Considerations:

All active substitute parts maintain ROHS3 compliance or equivalent RoHS compliance. The 4282-3-18-D and all substitute parts are classified as REACH Unaffected or Vendor Undefined, indicating no additional regulatory restrictions on component selection.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 4282-3-18-D with any of the listed parts in existing assemblies?

A: Yes. All listed substitute parts maintain identical electrical and mechanical parameters including connector type, position count, pitch, row configuration, mounting type, termination method, and fastening mechanism. Physical interchangeability is confirmed across all active and obsolete parts listed.

Q: What is the difference between the CNC Tech 4282-3-18-D and the Molex 0039013183?

A: The primary differences are manufacturer and connector color. The CNC Tech part is white; the Molex part is natural. Both are 18-position plug housings with 4.20mm pitch, crimp termination, and locking ramp fastening. The Molex part belongs to the Mini-Fit Jr 5559 series and has significantly higher inventory availability.

Q: Why is the 1-1969598-8 marked as Obsolete?

A: The 1-1969598-8 is classified as Obsolete by TE Connectivity, indicating discontinued production. While functionally equivalent and currently available in inventory, this part should not be selected for new designs. Active alternatives from TE Connectivity include 1-1969604-8 and 1-1969612-8.
