Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 4-1393486-4 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: D-Sub
• Connector Type: Plug, Male Pins
• Number of Positions: 25
• Number of Rows: 2
• Shell Size, Connector Layout: 3 (DB, B)
• Mounting Type: Free Hanging (In-Line)
• Termination Type: IDC
• Shell Material, Finish: Steel, Tin Plated
• Contact Finish: Gold
• Flange Feature: Housing/Shell (Unthreaded)

The substitute part 1-745496-7 meets all mandatory matching parameters. This part is currently active in production status and maintains full compliance with ROHS3 and MSL 1 specifications, providing a direct functional replacement for the obsolete 4-1393486-4.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 1-745496-7 is the appropriate replacement for the obsolete 4-1393486-4 based on the following engineering criteria:

Product Status: The main part 4-1393486-4 is classified as obsolete, while the substitute 1-745496-7 is active in production. This transition ensures continued availability and supply chain stability.

Compliance Alignment: Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring regulatory and environmental compatibility across applications.

Functional Equivalence: The substitute part matches all critical connector parameters including shell size, pin count, termination interface, and contact specifications. The termination difference (ribbon cable versus discrete wire) represents a functional enhancement, as IDC connectors designed for discrete wire termination are compatible with ribbon cable applications through appropriate cable preparation.

Enhanced Specifications: The substitute part provides documented electrical specifications (250V voltage rating, -55°C to 105°C operating temperature range) and material specifications (UL94 V-0 flammability rating, thermoplastic glass-filled dielectric) that were not specified in the original part, offering improved design documentation for system integration.

Frequently Asked Questions (FAQ)

Q: Can 1-745496-7 directly replace 4-1393486-4 in existing assemblies?

A: Yes. Both connectors share identical shell size (3, DB/B), pin count (25), row configuration (2), mounting type (free hanging in-line), and contact specifications (gold-plated signal contacts). The connectors are mechanically and electrically interchangeable.

Q: What is the difference between IDC ribbon cable and IDC discrete wire termination?

A: The main part 4-1393486-4 is specified for IDC ribbon cable termination, while the substitute 1-745496-7 supports IDC discrete wire termination. Both termination methods use insulation displacement contact technology. The discrete wire variant accommodates individual wire connections and is compatible with ribbon cable applications when the ribbon is properly prepared and inserted into the contact positions.

Q: Are there any compliance differences between the two parts?

A: Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) ratings. The substitute part provides additional compliance documentation including UL94 V-0 flammability rating and REACH Unaffected status, whereas the main part does not specify these parameters.

Q: What is the packaging difference?

A: The main part 4-1393486-4 packaging is not specified in available documentation. The substitute part 1-745496-7 is supplied in bulk packaging. Packaging format should be confirmed with the supplier based on specific procurement requirements.

Q: Does the substitute part support the same voltage and temperature ranges?

A: The main part 4-1393486-4 does not specify voltage or operating temperature ratings. The substitute part 1-745496-7 is rated for 250V and operates across -55°C to 105°C. These specifications should be verified against system requirements to ensure compatibility.

Q: What is the AMPLIMITE HDE-20 series designation?

A: AMPLIMITE HDE-20 is the product series designation for the substitute part 1-745496-7. This series designation does not appear in the documentation for the main part 4-1393486-4. The series provides additional product line identification for procurement and technical reference purposes.
