TE Connectivity 1658618-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1658618-1 is a 40 position rectangular receptacle connector with IDC (Insulation Displacement Contact) termination and gold plating. This connector is designed for ribbon cable applications with a 0.100" (2.54mm) pitch configuration in a 2-row layout. The part is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are necessary when the primary part experiences extended lead times, inventory constraints, or when design flexibility permits the use of equivalent connectors from alternative manufacturers that maintain electrical and mechanical compatibility within the specified parameter range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 1658618-1 is determined by strict adherence to the following core parameters:

Critical Matching Parameters:

• Connector Type: Receptacle
• Number of Positions: 40
• Pitch: 0.100" (2.54mm)
• Number of Rows: 2
• Row Spacing: 0.100" (2.54mm)
• Cable Termination: IDC
• Wire Type: Ribbon Cable
• Contact Finish: Gold
• Mounting Type: Free Hanging (In-Line)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts meet these critical parameters. Variations in contact type (Forked versus Female Socket), features (Feed Through, Strain Relief, Polarizing Key, Closed End), contact finish thickness, and color do not preclude substitution when the core electrical and mechanical parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full compliance with ROHS3 regulations and REACH unaffected status, ensuring regulatory compatibility with the primary TE Connectivity 1658618-1 part. All parts carry Active product status, confirming ongoing manufacturer support and availability.

3M 89140-0001 provides the highest inventory availability at 15,389 pieces with Feed Through features and is suitable for general-purpose ribbon cable applications requiring 40-position IDC connectivity.

3M 89140-0101 offers 11,058 pieces in stock with integrated Polarizing Key features, providing mechanical keying for applications requiring connector orientation control.

3M 89140-0003 supplies 1,867 pieces with both Feed Through and Strain Relief features, addressing applications with cable stress management requirements.

3M 3417-6040 provides 809 pieces with Strain Relief and Feed Through features in the 3000 series configuration.

3M 3417-7040 supplies 748 pieces with Closed End and Strain Relief features, suitable for sealed connector applications.

HARTING 09185406803 offers 1,074 pieces with Polarizing Key and Feed Through features, providing cross-manufacturer compatibility.

Selection between substitute parts depends on specific application requirements for strain relief, polarizing key functionality, and connector end configuration, all of which are available across the substitute options while maintaining core electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the HARTING 09185406803 directly replace the TE Connectivity 1658618-1?

A: Yes. Both connectors share identical critical parameters: 40 positions, 0.100" pitch, 2-row configuration, IDC ribbon cable termination, gold contact finish, and ROHS3 compliance. The HARTING part includes a Polarizing Key feature not present in the TE Connectivity part, which does not prevent substitution but adds mechanical keying capability.

Q: What is the difference between the 3M 3417-6040 and 3417-7040 models?

A: Both parts are 40-position IDC receptacles with identical electrical specifications. The primary difference is the connector end configuration: 3417-6040 features Feed Through design, while 3417-7040 features Closed End design. Selection depends on whether the application requires signal pass-through capability or sealed connector termination.

Q: Are all substitute parts suitable for ribbon cable applications?

A: Yes. All substitute parts are specified for ribbon cable termination with IDC contact technology and support 26-28 AWG wire gauge specifications.

Q: Do the substitute parts maintain the same contact finish specifications?

A: All substitute parts feature gold contact finish. Contact finish thickness varies: TE Connectivity 1658618-1 specifies 15.0µin (0.38µm), while 3M parts specify 30.0µin (0.76µm). Both thicknesses provide gold plating for corrosion resistance and electrical conductivity in IDC applications.

Q: Which substitute part offers the best inventory availability?

A: The 3M 89140-0001 provides the highest inventory level at 15,389 pieces in stock, followed by 3M 89140-0101 at 11,058 pieces.

Q: Are all parts ROHS3 compliant?

A: Yes. All listed parts, including the primary TE Connectivity 1658618-1 and all substitute options, are ROHS3 compliant and REACH unaffected.

Q: What connector features differ between substitute options?

A: Feature variations include Feed Through (standard signal pass-through), Strain Relief (cable stress management), Polarizing Key (mechanical orientation control), and Closed End (sealed termination). These features do not affect core electrical compatibility but address specific application requirements.

Q: Can I use a substitute part with Polarizing Key in an application designed for the non-keyed TE Connectivity part?

A: Polarizing key features add mechanical keying without affecting electrical performance. However, physical connector mating may be restricted if the mating connector lacks corresponding key slots. Verify mating connector compatibility before substitution.
