Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1-746290-2 is based on electrical and mechanical compatibility within the AMP-Latch series. The substitute part 1-1658620-2 maintains identical specifications across all critical parameters that determine functional interchangeability:

Critical Matching Parameters:

• Connector type (Receptacle)
• Position count (64)
• Pitch and row spacing (0.100" / 2.54mm)
• IDC cable termination method
• Wire gauge rating (26-28 AWG)
• Contact type (Forked)
• Contact finish material (Gold)
• Mounting configuration (Free Hanging, In-Line)
• Series designation (AMP-Latch)

The substitute part differs in product status (Active versus Obsolete), packaging format (Tube versus unspecified), contact finish thickness (15.0µin versus 30.0µin), and RoHS compliance status. These differences do not affect electrical or mechanical compatibility in standard applications.

Parameter Comparison

Engineering Selection Recommendations

The 1-1658620-2 serves as the direct functional equivalent to the obsolete 1-746290-2. Selection of the substitute part is based on the following engineering considerations:

Product Status: The 1-1658620-2 maintains Active product status, ensuring continued availability, manufacturing support, and supply chain reliability. The original 1-746290-2 is classified as Obsolete, creating supply constraints and potential discontinuation risks.

Compliance and Certifications: The 1-1658620-2 is RoHS3 Compliant, meeting current regulatory requirements for restricted substances in electrical and electronic equipment. The original part is RoHS non-compliant, which may present compliance challenges in applications subject to RoHS directives.

Electrical and Mechanical Compatibility: Both parts maintain identical specifications across all functional parameters including connector geometry, contact configuration, termination method, and wire gauge rating. The parts are mechanically and electrically interchangeable in standard applications.

Contact Finish Thickness: The substitute part features a contact finish thickness of 15.0µin (0.38µm) compared to 30.0µin (0.76µm) on the original part. Both thicknesses fall within industry standards for gold-plated contacts and do not affect connector performance in typical operating conditions.

Packaging: The substitute part is supplied in Tube packaging, which is standard for production and field service applications.

Frequently Asked Questions (FAQ)

Q: Are the 1-746290-2 and 1-1658620-2 mechanically interchangeable?

A: Yes. Both connectors maintain identical pitch (0.100" / 2.54mm), row spacing (0.100" / 2.54mm), position count (64), and mounting configuration (Free Hanging, In-Line). The connectors are mechanically interchangeable in all standard applications.

Q: Are the 1-746290-2 and 1-1658620-2 electrically interchangeable?

A: Yes. Both connectors feature identical contact type (Forked), contact finish (Gold), wire gauge rating (26-28 AWG), and termination method (IDC). The connectors are electrically interchangeable for ribbon cable applications.

Q: What is the significance of the contact finish thickness difference?

A: The original part features 30.0µin (0.76µm) gold plating while the substitute features 15.0µin (0.38µm). Both thicknesses meet industry standards for gold-plated contacts. The difference does not affect connector performance, contact resistance, or durability in typical operating environments.

Q: Why is RoHS compliance important for this substitution?

A: The 1-1658620-2 is RoHS3 Compliant, meeting current regulatory requirements for restricted substances. Applications subject to RoHS directives require compliant components. The original 1-746290-2 is RoHS non-compliant and may not be suitable for regulated applications.

Q: What packaging format is supplied with the substitute part?

A: The 1-1658620-2 is supplied in Tube packaging, which is standard for production and field service applications.

Q: Is the substitute part available in higher quantities?
