Key Parameters

Substitute Part Grouping Explanation

Substitution of the 745495-3 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must match the following critical parameters:

• Connector style: D-Sub
• Connector type: Receptacle, Female Sockets
• Number of positions: 25
• Number of rows: 2
• Shell size and layout: 3 (DB, B)
• Mounting type: Free Hanging (In-Line)
• Termination method: IDC, Discrete Wire
• Shell material and finish: Steel, Tin Plated
• Contact finish: Gold at 30.0µin (0.76µm) thickness
• Voltage rating: 250V
• Operating temperature range: -55°C ~ 105°C
• Wire gauge compatibility: 20-22 AWG
• Contact material: Phosphor Bronze
• Dielectric material: Thermoplastic, Glass Filled
• Flammability rating: UL94 V-0
• Color: Black
• MSL rating: 1 (Unlimited)

The substitute part 1-745495-9 meets all these criteria and is therefore a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 1-745495-9 is a direct substitute for the 745495-3 based on complete electrical and mechanical parameter equivalence. Both connectors share identical specifications across all functional criteria including connector geometry, termination method, contact materials, voltage rating, and operating temperature range.

The primary distinction between these parts is product status and regulatory compliance. The 745495-3 is obsolete and carries RoHS non-compliant status with vendor-undefined REACH compliance. The 1-745495-9 is an active product with ROHS3 compliance and REACH Unaffected status, making it the preferred selection for new designs and ongoing system support where regulatory compliance is required.

Both parts are manufactured by TE Connectivity AMP Connectors within the same AMPLIMITE HDE-20 series, ensuring design continuity and interchangeability in applications currently using the 745495-3.

Frequently Asked Questions (FAQ)

Q: Can the 1-745495-9 be used as a direct replacement for the 745495-3 in existing applications?
